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

A sudden power outage plunged the workshop into darkness. She took the opportunity to wind the silk into a ring. The silk modified with the fluorescent protein gene glowed a faint lake blue in the dark.

There was a knocking sound outside the window. The two men lifted the rainproof cloth and found abandoned components of Jiangnan residential buildings piled up in the backyard.

Hannah's trekking pole poked the carved door panel, and a glass bead suddenly rolled out of the wormhole, embedded inside it was the missing part of the Luban lock.

Lu Yong turned the pearl towards the setting sun, and a complete map of the park's secret passages was projected on the ground, with a red dot marked three meters below the silkworm room.

The cast iron spout of the teahouse was bubbling with bubbles, and Hannah was worried while fiddling with the tea: "Is this Longjing tea better than the alkali sedge tea from Red Beach?"

The tea artist suddenly held her wrist and said, "Miss, there is luminous silk from the silkworm room on the back of your hand. You need to use 80-degree water to dissolve it."

When the purple clay teapot was tilted, the steam condensed into a map in front of Hannah's eyes.

She instinctively reached out to stir it, but it wet the Luban Lock parts drawing. The lines stained by the tea gradually became clear - the entrance to the secret passage was actually on the blue brick floor under the tea table.

Lu Yong tapped the brick surface in the name of adding water. The hollow echo startled the tea artist and he broke the tea pet.

Hannah took the opportunity to turn over the movable bricks, and damp and moldy air wafted out wrapped in Zhang Fa's brittle "1985 Park Reconstruction Plan".

In the flashlight beam, the pen handwriting scribbled: "On July 7, a weather mapping instrument from the Japanese puppet period was found in the underground palace..."

The She inkstone in Bimoxuan is covered with golden star patterns, and Hannah's wolf-hair brush is always dipped in more ink.

When the administrator was demonstrating how to hold a pen, she suddenly discovered that there was a contour map engraved on the base of the inkstone - which completely overlapped with the projection of the silkworm room glass beads!
He pretended to accidentally knock over the inkstone, allowing the thick ink to seep into the gaps between the floor tiles.

When Lu Yong wiped the ink stain, the entire floor tile suddenly sank half an inch, and the wall could be heard making a sound of gears meshing. The Duobao Pavilion slowly moved away, revealing a spiral stone staircase leading downwards. Hannah's silk ring shone like a beacon at this moment.

The damp steps were covered with moss. Hannah felt a bump on the wall with her hand. The flashlight on her cell phone illuminated the wall. The serial number from 1943 and the signature of the maintenance team from 1979 overlapped each other. The latest mark was from three days ago. Lu Yong suddenly turned off the light source: "There is a blue light below!"

Deep in the darkness, the meteorological instrument wrapped in waterproof cloth was rotating, and the fluorescent screen showed completely different air pressure data.

Hannah's silk suddenly stretched and pointed somewhere. She opened the pile of observation logs and saw a map of the migratory routes of migratory birds in Liaodong Bay. The marked observation point was exactly the reed swamp where they were trapped yesterday.

.........

Before the morning dew had dried, Lu Yong's jeep had already rolled over the gravel beach and stopped steadily.

Hannah pushed open the car door and stepped into the soft mud on the tidal flat. The coolness ran up her back along her toes: "This feels different from the silt in the Weihai wetland!" She leaned over and pushed aside the salty grass. The ochre-red saltwort seeds were undulating with the tidal pulse, like capillaries bulging as the earth breathes.

The proprietress of the fishing house came towards them carrying a bamboo basket and said, "Try the freshly blanched sandworms. The dipping sauce can cover up the fishy smell." Hannah stared at the twisted milky white creatures and took a half step back, but Lu Yong picked one up and looked at it in the morning sun: "This is clearly a miniature version of the Yellow River Ancient Road loach."

Just as the tip of his tongue touched the tail end of the sandworm, a whistle suddenly sounded from deep in the mudflat - three motorboats loaded with fishing nets were cutting through the morning mist, and the startled water birds formed silver ribbons at the stern of the boats.

Hannah clutched the life jacket belt in worry: "This slipknot is more complicated than the silk reeling machine in Jiangnan Fengqing Garden!" The captain held a reed in his mouth and laughed: "Girl, stay on the port side. It will be more exciting to pass through the lock than riding a pirate ship!"

As the boat passed the rusty lock gate, Hannah's sun protection sleeve hooked the fishing net buoy. When Lu Yong rescued her, he found that the buoy was hollow inside, hiding a yellowed waterproof paper: "In July 2005, green turtles were released here." The handwriting was mottled by salt erosion, but Hannah exclaimed to the GPS locator: "Our current location is exactly the turning point of the migration route of sea turtles in Liaodong Bay!"

Suddenly, strange ripples appeared on the water surface, and the captain turned the steering wheel sharply. Hannah staggered and caught a glimpse of a blue-gray dorsal fin breaking through the water surface, while Lu Yong's camera only captured half of the tail fin: "It's a finless porpoise! ​​It's much more vivid than the specimens at the observatory!" In the interweaving of light and shadow, the streamlined figure had disappeared in the muddy Yellow River water, leaving only ripples that crushed their reflections.

The wooden fishing platform that stretched out to the center of the river creaked, and Hannah's fishing rod was tangled in algae for the third time. "The parabola of your casting is like a parabola function that you haven't learned well." Lu Yong suppressed his laughter and adjusted the float. Before he finished speaking, Hannah's fishing line suddenly stretched into a sharp angle, and the fishing rod bent into a full moon shape.

What was pulled up from the turbid water was not a fish, but a green-shelled crab. The claws held the hook tightly, and the bright yellow crab eyes reflected Hannah's flushed face. "This is a sub-adult Chinese mitten crab." Lu Yong used buckets of river water to make a home for it. "When the autumn wind blows, they will swim along the Raoyang River to the Bohai Bay."

The crab claws suddenly released the hook, making a harsh sound on the bottom of the plastic bucket. Hannah squatted down to observe: "It has a ring on its claws!" The micro-metal piece was engraved with "Panjin Fisheries Research Institute 2023", and the serial number was mostly covered by algae. The two decided to send it to the inspection station on the way back, but they didn't notice that the fine sand at the bottom of the bucket was quietly forming a miniature migration route map.

The midday sun brought with it the smell of cattails, and Hannah's sun hat became a net for catching insects. Lu Yong broke off a cattail stick and used it as a teaching stick: "Pay attention to the frog eggs in the leaf sheath, which is the birthing room of the black-spotted side-folded frog." Before he finished speaking, the entire cattail bush suddenly moved without wind, and brown waves rushed in from far and near.

"It's a herd of elk!" Hannah's exclamation startled the leading male deer. It raised its coral-like horns, and its wet fur flung out a string of mud spots, which happened to hit Lu Yong's lens cap. A migrating group of more than 30 deer crossed the viewing road. The young deer curiously sniffed Hannah's hiking pole, and the hoof prints of the mother deer left a plum-shaped puddle on the asphalt road.

In the dust of the departing deer, Hannah found a crushed metal can. Lu Yong picked it up with a branch to identify it: "It's a cod liver oil can produced in 1958. The rust color can be used as an archaeological sample." They didn't notice that rainwater was accumulating in the depression of the can, and two sword water fleas were breeding in this miniature lake. The open-air stove of the fishing house was filled with the aroma of bean paste. Hannah was worried about the iron pot stewing miscellaneous fish: "The eyes of this crucian carp are brighter than those in the Berlin Aquarium!" The proprietress picked up the spatula to turn the catfish: "Fresh fish with open eyes are authentic, and those with closed eyes are frozen."

Lu Yong suddenly picked up a small transparent fish with chopsticks: "Silverfish! This should be eaten raw with tofu." Hannah closed her eyes and swallowed, but the tip of her tongue burst with sweetness: "It's like holding a mouthful of Dongding Oolong tea!" She didn't notice that the tabby cat under the eaves was staring at her covetously, and took away half of the fish tail while she was adding more rice.

The dessert after the meal was freshly baked Suaeda mooncakes. Hannah broke open the puff pastry and exclaimed: "The dark red filling looks like a frozen sunset!" The proprietress smiled and sifted out the grass seed powder: "Mixed with Suaeda from the tidal flats, it has three more sea flavors than Suzhou-style mooncakes." Where the cake crumbs fell, an army of ants were carrying their unexpected harvest and carving a winding food path on the table legs.

The setting sun dyed the river bay into honey color. Hannah followed the beach guard to learn how to carve a reed whistle. "You have to choose a reed that has been eaten by insects, so that the resonance cavity is transparent." The old man's cracked fingers flew, and the reed skin was cut into spiral patterns. When the whistle was first tested, the cattails on the other side suddenly stood up with triangular ears - it was a red fox!
Lu Yong's camera followed the fox's trail and found that it was digging for sandworms in the gaps between the plum blossoms on the mudflat. Hannah's reed whistle made a broken sound, and the fiery red figure immediately disappeared into the twilight, with a piece of silver fish scales hooked on the tip of its claws. The old man squinted and looked into the distance: "This kid has a gap in his left ear, which was left when he stole the dried mackerel I hung out to dry last year."

The evening breeze brought the roar of the diesel engines of the fishing boats, and Hannah's reed whistle mixed in. Lu Yong suddenly recognized the melody: "Is it "Love of the Rhine"? " She smiled and threw the reed whistle into the center of the river: "Now it should be called "Love of Raoyang Bay." The whistle floated downstream, and the river bay that startled the night herons began to swallow up the stars and the moon.

The mudflats glowed with silver scales under the moonlight, and Hannah's rubber boots sank into the ripples after the tide receded. Lu Yong held up an ultraviolet flashlight and scanned: "Look! These radial lines are the night dance of fiddler crabs." The beam followed the movement of the crabs, and the claw marks on the ground actually formed the outline of the Liaodong Bay map, and the location of Panjin was shining with the pearly light of shellfish.

Hannah suddenly squatted down and touched the wet sand: "There is temperature here!" Her palm was pressed against the beach kissed by the tide half an hour ago, and the temperature difference between the ground heat and the moonlight intertwined on her skin. Lu Yong had just taken out the infrared thermometer when a fishing fire suddenly lit up on the breakwater in the distance, startling the hermit crabs and causing them to collectively retract into their shells.

Before returning, Hannah found that there was sea water in the tire tracks, so she dipped a reed in the water and wrote.

The tide suddenly came early, and the waves swallowed up the last stroke of "goodbye".

Lu Yong pointed to the newly leveled mudflat and said, "Nature's eraser is sharper than the one in an art museum." They didn't notice that the piece of reed with the words written on it was being pushed towards the river mouth by the tide and would become a navigation buoy for a migratory fish.

.........

The next day, the glass curtain wall of the Science Museum was swallowing up the morning glow. Hannah stopped applying sunscreen halfway through: "The whole building is absorbing the red light!"

Lu Yong raised the polarized lens to observe and found that the titanium dioxide coating on the facade was catalyzing the color development reaction of the alkali pigment. When the morning mist spread over the wetland, the ochre-red outline of the building was connected with the red beach on the horizon to form a lava flow.

The tour guide robot slid in front of them, and the electronic screen lit up with a video of the red-crowned crane's courtship dance. "Do you want a customized tour route?" The robot arm ejected a scent capsule, "This is a fragrance blended according to the flowering period of Suaeda salsa." Hannah chose the July limited edition, and the scent of citrus mixed with sea salt exploded at the moment. A group of sandpipers happened to fly by the floor-to-ceiling window, and their orange-red legs complemented the light beam of the chromatograph in the museum.

The holographic sand table shows the history of tidal creek changes. Hannah's fingertips poked the track of the 1987 typhoon. In the year that was lit up, the virtual Suaeda salsa suddenly grew wildly into a three-meter-high wave. "This is a simulation of the mutation caused by the sudden drop in soil salinity." The researcher started the repair program, and the red vegetation collapsed back to a carpet shape. "In the real world, they use their roots to weave the breakwater."

Lu Yong squatted down to touch the living sample under the glass floor. The Salicornia seedlings in the culture dish were secreting amber mucus. Hannah's camera zoomed in for a close-up: "Is it like injecting moisturizing essence into the soil?" The real-time monitoring screen suddenly sounded an alarm. It turned out that the concentration of carbon dioxide she exhaled affected the micro-ecosystem. The two hurriedly took three steps back and knocked over the salt marsh food chain building block wall.

The seats in the surround screen cinema vibrate with the frequency of migratory birds flapping their wings. Hannah clenched the armrests: "This is more shaking than the black-sailed boats in Jiangnan Fengqing Garden!" When a flock of Siberian cranes flew past the camera, the seats suddenly tilted back 90 degrees, and they seemed to lie in the down feathers on the cranes' backs. The surround sound system blasted the sound effect of the ice breaking, and Hannah's earlobes suddenly felt the warmth - the seat headrest simulated the body temperature of the mother crane incubating eggs.

When the lights came back on, Lu Yong found a simulated feather stuck in Hannah's hair. "This is the summer feather of a demoiselle crane." He compared the texture with the specimen wall, "The electromagnetic device deliberately set up an Easter egg." The two searched through the seats for more feathers, but triggered a hidden program: the dome projected a star map of all the birds in Liaodong Bay, and the tail feathers of the Cygnus were pointing to the place where they parked in the morning.

The interactive experimental table was equipped with a miniature mudflat model. Hannah followed the prompts to inject fresh water. The originally bright red Suaeda colony quickly faded to yellow-green, and the cell vacuoles in the electron microscope screen shrank collectively. "Hurry up and add seawater!" Lu Yong's hands trembled as he sprinkled half a bag of sodium chloride. The revived red algae crawled along the drainpipe to the sink, and coral-like crystal flowers bloomed on the ceramic surface.

The cleaner smiled and closed the ion gate: "Last month, an intern really cultivated a cold-resistant variant, and it grew into a red carpet in the men's restroom." Hannah took the opportunity to collect crystal samples, but saw Lu Yong filling a test tube with sea mud: "Take it back and cross it with the mint you planted. Maybe you can cultivate a perfumed red beach." Their playfulness startled the ventilation system, and a ball of down feathers suddenly fell from the exhaust filter - it was the remnant of the nesting material of the Chinese hwamei, and the aluminum fragments from last year's ringing were still stuck between the fibers.

The tiles in the Prism Corridor change color with each step. Hannah jogs after the blue-purple light spots: "This is more elusive than the tide marks in Raoyang Bay!" Lu Yong stops to stare at the iridescence projected on his sleeves and finds that the spectrum sequence actually corresponds to the changes in the carotene content of Suaeda salsa. When Hannah's shadow overlaps with his, the mixed orange-red color matches the Pantone color number of the real grassland outside the window.

The mirror house at the corner holds a surprise: bird silhouettes float in the infinitely reflected red light.

Hannah reached out and touched the illusion of the mallard duck, and all the mirror images suddenly collapsed into the vermilion crown of a red-crowned crane.

The administrator in the control room tried to hold back his laughter: "You are the seventh pair of tourists to trigger a courtship scene today." The two embarrassed people did not realize that the pressure sensor in the mirror interlayer had recorded their overlapping heartbeat rates.

The setting sun shines through the bone china lampshades in the specimen museum, gilding the tip of the black-faced spoonbill's beak.

Hannah leaned in to observe the bird stomach contents display cabinet: "How many kinds of shells has this heron swallowed?" The holographic label automatically popped up a diet analysis chart, and the rainbow cherry clams unique to Liaodong Bay accounted for the largest proportion. Lu Yong suddenly pulled her to a dark corner, where the seeds of Suaeda salsa were dancing behind the fluorescent screen under the ultraviolet light.

Hannah followed the scent of preservatives mixed with caramel to find the coffee bar. The latte artist used beetroot powder to create a red beach pattern, and a family of swans floated on the surface of her cappuccino.

When Lu Yong's latte vortex engulfed the last piece of "land", the low tide alarm in the real world suddenly sounded. The two rushed to the viewing window and saw the last trace of crimson disappear into the deep blue twilight. (End of this chapter)
