Coach: Coaching the Grizzlies at the beginning, playing the bantam

She stepped barefoot onto the creaking floor and found Lu Yong drawing on the recorder by the window - the bird-shaped curve he drew with condensed water just covered the pressure peak that was jumping on the screen.

Garidi in the morning mist looked like an undeveloped film. The two followed Lao Wu to check the remains of the bird net.

The cut nylon rope was still entangled with the heron's down feathers, and Lu Yong suddenly kicked the metal box half buried in the soil.

Hannah used a reed to pry open the rusty lock. In the yellowed duty log was a pipeline inspection map from 1987. The vulnerable section marked with a red line was exactly where the hot spring leaked yesterday.

“Back then, there were so many wild ducks here that they committed suicide by crashing into the oil pipelines,” Old Wu lit a cigarette, and the sparks scared away the gathered damselflies. “Now we have to use drones to drive the birds away.”

Hannah suddenly pointed to the sky. A flock of demoiselle cranes returning north were skillfully passing through the pipe matrix. The friction between their gray and white feathers and steel turned into tiny notes.

When a sudden rainstorm hit, they were trapped in an abandoned metering station.

The raindrops hit the tin roof to the rhythm of Andai dance. Lu Yong's hand wiping the window glass suddenly stopped - a flock of migrating pelicans emerged from the rain curtain, and their huge wings spread as they flew over the pipes, as if they were installing temporary feathers on the rusty industrial skeleton.

Hannah found graffiti in the corner of the leaking wall, revealing the "1991 flood season water level line" under the peeling blue paint.

She stood on tiptoe to indicate the height of the notch, and a sudden gust of wind blew in from the vent above her head, blowing a page of the diary onto Lu Yong's back.

On the damp paper, a ranger from 3 years ago scribbled: "Today, we rescued a white-tailed sea eagle that had crashed into a pipeline. The crease on its left wing is the same shape as the crack on pipe No. ."

A double rainbow appeared after the rain stopped, spanning the entire wetland, but Old Wu stared at the changing face in the southwest.

The oil pipeline warning bell suddenly rang, startling the flock of rails and crashing into the rainbow, as if they had knocked over a paint bucket.

When the three men ran to the embankment, they saw the leaked crude oil spreading along the old river channel, with the end of the rainbow just inserted into the dirty oil film.

"We have to use fire to burn off the floating oil!" Old Wu dragged out the fuel tank from the bottom of the motorboat.

Hannah's hand holding the lighter was shaking. The moment the flame jumped up, Lu Yong pulled her into his arms.

The flames rose into the sky and turned into a second rainbow. The bone-crested chickens that fled in the black smoke made whistles-like cries, as if they were holding a sea burial for their burning reflections.

When the last sightseeing bus left before sunset, Hannah secretly put the rusty lock of the metering station into her pocket. Lu Yong pretended not to see her wet trouser legs. The pipeline numbers printed on the wet cloth were evaporating, turning into a tingling coolness on the skin. When the car passed the bend of the flood control embankment, the startled herons suddenly formed an arrow pointing to the golden reed marsh they found in the morning.

The starry sky of Garidi has three times more stars than the urban area, but it loses to the night lighting of the oil pumping station. Hannah lay on the roof of the observatory and found that the handle of the Big Dipper was hooking the outline of an oil pipeline. The red light of the cigarette butt between Lu Yong's fingers crossed the sky and formed a brief connection with the flare of the refinery 30 kilometers away, like some kind of cosmic calibration ceremony.

The dew in the late night wet the inspection map hung on the windowsill. Hannah added a flying bird with a ballpoint pen. The moment the pen tip pierced the paper, the alarm suddenly screamed, and the monitoring screen showed that a creature touched the infrared light of tube 7. The two followed Lao Wu into the night. At the end of the flashlight beam, the injured Oriental white stork was knocking on the pipeline with its long beak, and the metal echo was mixed with the gurgling sound of flowing oil.

When the morning mist came again, Garidi was like a reset game scene, and Hannah's canvas shoe prints overlapped with yesterday's to create a mystery. Lu Yong drew the intersection of the pipeline and the bird path on the breakfast tablecloth, and the collision area marked with ketchup just covered the oil stains. Old Wu chewed a pickled cabbage bun and muttered, "It's time to paint the pipeline with a warning color," and then glanced out the window, "But how can migratory birds recognize the safety color of humans?"

When the return bus started, Hannah's forehead was pressed against the window.

In the morning light, the dewdrops condensed on the surface of the oil pipeline are being wiped off by the early shift workers. In those falling water droplets, perhaps the last pupils of a night heron reflecting the sky are hidden.

Half a line of lyrics leaked out of Lu Yong's Bluetooth headset, mixed with the roar of the engine, and formed a perfect chord with the explosion sound of burning crude oil yesterday.

Hannah was scraping the asphalt stains on her cuffs with her fingernails when the sound of tires ripped through the silence of the prairie.

The giant billboard of Daqing Racing Town was flashing a hundred meters away. Under the words "Speed ​​Racing" spelled out by neon tubes, three sand larks were pecking at the energy gel particles scattered by the sponsor.

Old Wu took off his wetland ranger badge and replaced it with a safety officer armband with oil stains. "Each lap on the grassland track consumes eight liters of gasoline," he kicked the withered Suaeda salsa by the fence, "enough for these grasses to drink for three years." Lu Yong's camera followed the modified car whizzing by, and the heat waves from the exhaust pipe melted the dandelion seeds into transparent empty shells.

Amid the smell of synthetic motor oil wafting from the maintenance area, Hannah discovered an abandoned bird's nest hidden behind a rusty parts rack. Six pale blue eggs glowed like coolant, and the eggshells were still clinging to fragments of last year's race tickets. "It's a starling's nest," Old Wu knocked on the bracket with a wrench, "they always mistake antifreeze for dew."

Amid the cheers of the champion driver's autograph session, three lawn mowers were crushing the vegetation in the buffer zone. Hannah bent down to pick up a half-cut ring-necked pheasant tail feather. The snow-melting agent crystals on the root of the feather were corroding the iridescence. Lu Yong suddenly pulled her back two steps. The car with a flat tire rushed past the isolation belt, and the flying carbon fiber fragments reflected rainbows in the sunlight.

"The cooling tower leaked and formed a saline lake," Old Wu pointed at the white crystal band outside the track, "and the geese would become dehydrated if they drank it." Before he finished speaking, four shelduck ducks mistook the asphalt road for water and landed in the tire tracks, leaving messy scratches. When the maintenance team came running with the oil-absorbing felt, the ducks had already flown crookedly towards the smoking barbecue stall.

Warm air gushed out of the ventilation vents of the underground oil depot, and Hannah's scarf was blown into a sail. The moment Lu Yong reached out to grab it, wintering swallows suddenly rolled out of the airflow, and the turbulence they cut with their wings caused three side-by-side racing cars to deviate from their tracks at the same time. The engineers in front of the monitoring screen stared at the data fluctuations, and no one noticed the down hanging on the ventilation grille.

When the night race started, Hannah climbed up the observation tower. The moths in the searchlight beam were shattered by the roar of the engine, and the scale powder and gunpowder mixed into a strange coating on the billboard. Old Wu chewed an energy bar and muttered: "Last year, a long-eared owl crashed into the rear wing of a racing car, and its feathers got stuck in the turbine, causing a series of rear-end collisions."

Lu Yong's night vision camera suddenly captured an unusual light spot - in the bushes outside the buffer zone, poachers were using laser pens to lure light-seeking birds. The light path of a swooping kestrel was entangled with the taillights of a racing car. Hannah grabbed the intercom and was about to call, but Old Wu had already swung a fire extinguisher and smashed it at the poacher's electric car. The exploding dry powder was like an artificial avalanche, and the startled flocks of egrets formed a temporary no-travel net above the track.

When the laser show at the post-race party pierced the clouds, Hannah noticed something strange in the bathroom. On the condensed mist on the mirror, the migrating cranes were leaving water marks with their beaks, and the fireworks reflected in the mirror outside the window just happened to explode into the same migratory formation. The moment she stretched out her hand to wipe out the water vapor channel, the fireworks debris fell into the landscape pool, and the koi mistook it for plankton and scrambled for it frantically. The racing town in the morning mist looked like an unassembled Lego. Hannah stepped on the dew and sneaked into the closed test area. The claw marks of the night heron left on the asphalt patch formed mysterious characters. She took out the gear she picked up yesterday for comparison, and the tooth marks matched the arc of the claw marks. Lu Yong's drone suddenly flew over his head, and the shadow cast startled the turtledoves hiding in the drainpipe. The airflow stirred by the flock of birds suddenly made the test car data abnormal.

When the flowers on the podium began to wilt, Old Wu led them into the underground pipe network. The flashlight swept across the water seepage, and the Chinese toad was devouring beetles swollen by gasoline. Hannah's soles were stuck with some kind of glue - it was the amber sealed when the track was laid 20 years ago, and the insect wings and the racing paint were chasing each other forever in the resin.

"Underground oil pipelines and the geomagnetic induction lines of migratory birds overlap," Old Wu knocked on the rusty warning sign, "Last month a speed radar diverted three thousand sand cones." Lu Yong's compass was spinning wildly here, but Hannah's hair was floating upwards against gravity, as if the invisible wings were taking shape.

The sudden downpour turned the muddy track into a swamp. In the mud waves rolled up by the tires of the rescue vehicle, Hannah caught a glimpse of a reflective metal ring. It was the red-legged falcon ring that had been missing for three years. It was now entangled between the gears of the winch and was pulled into the surging mud along with the wire rope. In the slow-motion footage shot by Lu Yong in the rain, the cold light reflected by the ring formed a twin mirror image with the chrome surface of the championship trophy.

During the midnight maintenance period, Hannah felt an abnormal vibration at the edge of the cooling pool. The racing stickers deposited on the bottom of the pool were dissolving, and the bubbles that emerged formed an aerial corridor for migrating birds. Old Wu threw out a thermometer: "The geothermal heat is abnormal, and this pool has become an artificial hot spring." Before he finished speaking, the wood frogs that woke up from hibernation had jumped into the pool, and the synthetic dyes absorbed by their skin turned them into moving warning lights.

When the salute at the closing ceremony rehearsal scared off the skylarks, Hannah found a crack under the VIP seats. After prying open the loose floorboards, the 1989 race map and bird banding records were stacked together. On the yellowed paper, a certain curve was circled in red pen, with a note next to it: "Swifts' cornering speed exceeded 240km/h." Today's speedometer shows that the maximum speed of the latest racing car is also exactly 240.

At the last moment before the lights went out in the racing town, Hannah put the gear into the abandoned starling nest.

The moonlight turned the tooth grooves into piano keys, and the tones produced by the passing night wind unexpectedly matched the resonant frequency of the oil pipeline thirty kilometers away.

Lu Yong took a picture of her looking up at the starry sky. In the light pollution of the billboard behind her, the outline of Cygnus' wings could barely be made out.

.........

The glass dome of the Daqing Museum filtered the September sunlight into a light golden color. As Lu Yong adjusted the camera parameters, Hannah had already jumped in front of the statue of the oil worker.

"Look at the reflection of the oil stains on the helmet!" She pointed at the mottled marks on the forehead of the bronze statue, "Does it look like the asphalt nebula we saw in the racing town yesterday?"

The two followed the arrows on the electronic guide and walked into the paleontology hall, where they ran into a three-story-high mammoth skeleton. Hannah's canvas bag brushed against the AR interactive screen, and the sleeping prehistoric giant suddenly raised its long nose in the holographic projection, startling her so much that she took a half step back and bumped into Lu Yong's arms. "This is a pregnant mammoth mother." The elementary school student tour group squeezed past them, and the childish voices echoed in the exhibition hall.

Lu Yong squatted on the ground to take pictures of the cracks on the fossil base, while Hannah stared at the moss specimens in the glass display case. "These green dots are more vivid than the moss stickers on our car." The hot air she exhaled formed a white mist on the glass, instantly blurring the plant spores from 10,000 BC.

"Let's try fossil rubbing!" Hannah dragged Lu Yong into the parent-child activity area and grabbed a crayon to smear on the imitation rock slab. When the outline of the woolly rhinoceros gradually emerged on the paper, she suddenly nudged Lu Yong with her elbow: "Do you think this texture looks like the tire tracks in the racing town?"

The pumping machine model in the oil and gas exploration hall is simulating oil extraction operations. Hannah put her ear against the iron pipe decorative wall. "There is a real rumbling sound!" Her curly hair trembled slightly with the vibration. Lu Yong flipped through the exhibition hall brochure: "This is a real recording of an oil well in the 1960s."

In the replica cellar exhibition area, Hannah got into the scaled drilling platform and fiddled with the joystick, and the LCD screen suddenly popped up an animation of "Congratulations on drilling the first barrel of oil." Lu Yong captured the moment when she waved the virtual oil pipe, and the flash woke up the orange cat napping in the corner.

The old-fashioned TV in the folk exhibition hall played the movie clip of "Entrepreneurship" in a loop. Hannah sat in a pile of enamel basins set in the supply and marketing cooperative, pinning a red star hairpin on the end of her braid. "Do you look like a female technician in the Iron Man team?" She deliberately read the oath on the display board with a northeastern accent, causing Lu Yong to almost drop the old-fashioned telephone receiver in his hand.

In the wedding customs exhibition area, when Lu Yong's camera was aimed at the earthen kang covered with award certificates, Hannah suddenly emerged from the red wedding quilt with a few grains of simulated sorghum stuck on her head. "This photo is worth two cups of milk tea!" She shook an enamel pot she had found from somewhere, with a production slogan from 1972 printed on the bottom of the pot.

The digital exhibition hall's circular screen theater was showing "Million Years of Oil Reservoir". Hannah pulled Lu Yong to sit in the third row of the revolving stand. When the special effects of the crustal movement shook the seats, she suddenly pointed to the dome and said, "Look! The projection of the oil bubbles is the same shape as my earrings."

When they walked out of the theater, Hannah's canvas shoelaces came undone. When Lu Yong squatted down to tie the knot, the setting sun just passed through the glass curtain wall, pinning their shadows on the core sample display rack. The sedimentary lines of twenty geological ages now became the overlapping rings of light and shadow under their feet.

The resin amber in the souvenir shop was flowing with honey color under the spotlight, and Hannah held up a magnifying glass to observe the insect specimen. "The posture of this click beetle is like the grasshopper that hit the windshield in the racing town." She turned to ask the clerk behind the counter, "Can I customize the amber with a photo embedded in it?"

Lu Yong was studying a bookmark made of old ticket stubs at the cashier counter when Hannah suddenly stuffed a commemorative coin into his hand. The cool touch of the metal stunned him - on the back of the coin, in the panoramic view of the Daqing Oilfield, two sesame-sized figures could be vaguely seen standing on the observation deck.

The museum cafe was filled with the strange smell of crude oil, and Hannah scooped up a spoonful of black sesame ice cream in the shape of oil. "There's a surprise underneath!" She dug out the mango filling hidden at the bottom of the "drilling well", and the black sesame on the corner of her mouth looked like the organic matter spots in the core sample.

Lu Yong was stirring the latte of Iron Man Wang Jinxi, and the foam on the surface of the latte was slowly engulfing the figure wearing an aluminum helmet. Hannah suddenly pushed her phone over, and on the screen was her circle of friends: the nine-square grid of photos was interspersed with old photos from 1960, and the photo of the two people in the same camera position was almost indistinguishable from the real thing.

The setting sun shone obliquely into the dinosaur egg fossil exhibition hall. Hannah counted the cracks and suddenly exclaimed: "The direction of the cracks on the third one from the left in the seventh row is exactly the same as my palm prints!" When Lu Yong pinched her wrist for comparison, the security guard had already started the clearing broadcast.

They fought for the last piece of cardboard at the stamp table, and Hannah's mammoth stamp accidentally covered Lu Yong's oil well stamp. The two red inks blended into a strange purple, like an unknown rock layer suddenly appearing on a geological profile.

As they walked out of the museum, Hannah made a final face at the glass wall.

The shadow of a mammoth from 100,000 years ago suddenly resurrected in the night sky, and its long trunk just happened to wrap around her shadow.

In the photos taken by Lu Yong, the light spots from street lamps and display cabinet spotlights interweave into star clusters, falling on her flying hair like the rebirth of ancient plant spores.

"Are we going to the wetland to see the red-crowned cranes tomorrow?" When Lu Yong put the camera into his backpack, Hannah was drawing the route on the guide map with lipstick.

In the twilight, her lip prints just covered the coordinates of the observation deck on the top floor of the museum, like a fresh time capsule. (End of this chapter)
