Blue Star

Gu Li listened with bated breath. His perception ability was not as good as Iris's. Under the cover of the sound of water, he could hardly hear the so-called flying insects, but only the regular sound of instruments beating.

With his thumb against the ring, he waited for 10 minutes and didn't hear the flying insects that Iris said, maybe those flying insects can't get in for the time being.

"Let's go."

"Let's go now? I hate bugs the most!" Mimir couldn't help but feel his scalp tingle, and his whole body trembled at the thought of Xijia's ending, "Don't you set up a magnetic field protection? It's scary to just walk away like this."

Daoporing kicked away the garbage piled up at his feet, and said: "The entire river is covered with magnetic fluid. If we use magnetic field protection, we will be surrounded by iron walls, and we will not even be able to see the road."

From the time he went down the river, Gu Li put away all the magnetic fields.His magnetic field will attract ferrofluid, but wherever there is a magnetic field, the ferrofluid will follow the trend.

Although the magnetic field is controlled by him most of the time, as long as it is running, his skin and even his facial features will have magnetic field fluctuations.

He and his brother had run ferrofluid in training, but in such small quantities that even strong magnetic fields would not cause harm.The ferrofluid would swirl with his magnetic field, occasionally brushing his breath or skin.

But using a magnetic field in a river full of ferrofluid is no different from masochistic.

The brightness of the lighting crystal mine has been maximized, and almost everything around them can be seen clearly.Because the controlled magnetic field is too weak, there is only a small amount of ferrofluid wrapped around the wrist that holds the crystal ore, and it will not affect it for the time being.

Flying insects like light, so they should be looking for a light source now.However, after several minutes of their slow progress, no similar sound was heard.

The underground river flow has entered a slow state, and the depth of the water has gradually reached from the waist to the chest.The ferrofluid at the bottom was mixed with a lot of garbage, and part of it wrapped around magnetic things, forming a spherical shape underwater, seriously hindering the speed of progress.

In the deep water area, Iris half-floated on the surface of the water and pulled the climbing rope to lead the team.

This reminded Gu Li of an experimental dog he raised when he was a child. Before he was infected, he was tied to a leash and walked like this.

Fish walking people is really a novel sight.

The sound of mechanical beating became more and more clear after entering the deep water area. In addition, there was a small amount of sound of waterfall hitting the river.

He was almost certain that the regular beating sound was a waterwheel built next to a small waterfall.There used to be a similar one near the port of the former Fifth Town.

It just sounds like the material is different. The current one doesn't look like wood or steel.

"Is there no way ahead?" Mimir who was following behind asked.

Gu Li swam up to Iris who was leading the way, supported the rock wall at the end of the river, and checked the traces of the water level.

The water flow has become static at the moment, and the water level is so high that it is impossible to reach the bottom.Looking back, the height of the water surface is almost the same as the slope down, but there is no upward trend.

This underground river existed long before they were born, and it has been flowing for so many years, which means that there must be a water outlet at the bottom of the river.I just don't know if the water outlet is big enough for them to pass through.

The deep water area is wider than the back road, almost the size of a bedroom.The four of them formed a circle, and they were finally able to stretch their hands and feet freely.

The back is against the rock wall, and the body is vertical with the hand on the wall.He could feel that the magnetic fluid under the waist was flowing slowly, and the fabric of the trouser legs also had obvious suction.

It's just that the magnetic fluid blocked the underwater view, and he couldn't determine where the water outlet was.

Dao Porling twisted his wet beard, and said helplessly, "What can we do? If we go back to open the mountain and make a detour now, it will probably take us several days to waste."

While speaking, there was a sudden sound of insect wings flapping from a wall under the water, followed by the messy sound of insect mouthparts stabbing stainless steel.

He should really be thankful that he has such good hearing as Iris, and there are really flying insects.

Looking for the sound to get closer, I finally touched the top of a curved stainless steel door under the magnetic fluid that blocked the view.

"The exit is here."

This path was chosen out of desperation, but now it seems that their luck is good.

If I guessed right, this should have been a normal drainage channel.It was only later that the mutated experimental subjects became more and more uncontrollable, so they were completely blocked by the people who imprisoned them.

And because the test subjects were afraid of water that was not hot enough, the drain was not destroyed.

Dao Porling felt his head ache, "There's so much ferrofluid, how do we get down? I don't know where the switch is."

Iris let go of the climbing rope he was holding tightly in his hand, turned over and swam into the ferrofluid.

Gu Li didn't have time to stop it.But within 2 minutes, Iris swam up again.

These ferrofluids are insoluble in water, and the fine particles block the light.Even if Iris can stay underwater for a long time without breathing, it is difficult to find the switch by groping.

"I use a magnetic field to lure these ferrofluids away." Gu Li wiped away the water stains on his face, "If I move fast enough, I won't be suffocated to death."

"No." Dauporin was the first to object. "Using a magnetic field will block your airway. Who knows what will happen when these magnetic fluids enter the human body."

Gu Li smiled and pinched his nose, "Someone will help me plug my ears, it should be fine."

"I don't agree." Daoporing, who is also a wizard, knows what will happen to his body after using a magnetic field. "If there is a waterproof thing that can cover your head, it's fine. It's too easy to cause accidents."

After closing the words, Iris felt a plastic bag from the water. Although there were a few holes, it was enough to cover the facial features.

Gu Li took the plastic bag, "Look, isn't this here?"

Put some air in the plastic bag, wrap it around your head, and say to the other two: "Come closer to me, there will be a spherical space around me in a while. If the drainage gate is opened, we will definitely be washed out by the water."

Take a deep breath, squeeze the plastic bag with your left hand, and turn the ring with your right hand to drive the magnetic field to form a protective layer.

Just as Gu Li expected, the magnetic fluid in the water was adsorbed on the outside of the protective layer almost instantly, rotating regularly to form numerous V structures.From the outside to the inside, it looks like a sea urchin without long thorns.

Daoporing and Mimir were protected in it, watching Gu Li's body become a "black magnetic man" from head to toe.

The magnetic field emitted by Gu Li was so strong that it almost absorbed all the magnetic fluid at the bottom of the water, presenting the original scene of the bottom at a speed visible to the naked eye.

Without the propulsion of the magnetic fluid, the water, which is no longer clear enough, is actually full of discarded human garbage.Keys, plastics, and many non-degradable objects that have been unable to identify the prototype.While losing the magnetic fluid, it slowly sank to the bottom of the water and piled up into mountains.

The underwater stainless steel sluice gate reveals the spiral disk and the bottom two rows of small holes that are usually used for drainage.It's just that the hole is blocked by too much garbage now, and the water that can be drained out of the hole has become very little.

Iris bit the lighting crystal mine and swam to the bottom of the water, quickly tore away the garbage at the bottom of the gate, and vigorously rotated the spiral disk on the gate that had not been used for many years.

The ferrofluid covering around Gu Li became thicker and thicker, and the sphere was almost larger than the drainage gate.

He could only withdraw the magnetic field quickly, and use his talent again in a different position within a few breaths.

The mechanical friction sound of the spiral disk being forcibly rotated came from underwater.Ten seconds later, the gate was pushed open from bottom to top, and a brief siphon of water flow sucked several people in the ferrofluid into the gate.

The sphere, which lost its center of gravity, rotated upside down and hit the corridor.

Strong inertia threw Daoporin and Mimir out of the ferrofluid one after another, but fortunately, with climbing ropes tied around their waists, they were lucky enough to stumble in the spherical ferrofluid all the time.

Although the magnetic field defense layer covered with magnetic fluid can isolate the strong impacting water flow, the space of the sphere already contains some water that has not been removed.

Three people were trapped inside, struggling to breathe even without the ferrofluid cover.

Mimir choked several times in a daze, and wanted to curse a few words, but was suppressed while rolling.In the end, it was really uncomfortable to roll, so he tightened one end of the climbing rope, and simply hugged Gu Li, who was already covered in magnetic fluid.

"I'm about to have a concussion~~~"

The violent tumbling and turning made it difficult for Gu Li to hold his breath. These magnetic fluids that follow his magnetic field are like thousands of insects and ants. Even through the fabric of the military uniform, he can feel the dense tingling sensation, just like it will happen when the season comes. of static electricity.

The distance of the corridor is not that long, and the sphere felt weightless after bumping into it four or five times, and immediately sank to the bottom of the water like a shot put into the water.

Iris drilled into Gu Li's defensive layer by inertia, pulled the climbing rope binding the three of them and shuttled underwater.

Gu Li closed his eyes and couldn't see anything, he could only judge the current situation based on his feelings.

After rushing out of the tunnel, apart from the resounding sound of water, there were numerous insect wings flapping.This scalp-numbing sound can be clearly heard even underwater, and there are quite a few of them.

But soon, the voice became softer and gradually faded away until Iris called his name after coming out of the water.

Press the rotating ring with your thumb, and the moment the magnetic field is retracted, the magnetic fluid around you retreats to the ground like water.

The action violently tore off the plastic bag used to cover the facial features, and at the moment of inhaling fresh air, he even felt dizzy for a short time.

Iris hugged him, maybe because he felt that he was short of oxygen, and regardless of the presence of other people, he held his neck with one hand and let him breathe twice.

After recovering, Gu Li pushed the fish away, gasped and said, "I'm fine."

The passage leading them out was indeed an exit, built under a small waterfall.A waterwheel with a height of 20 meters is built on the side of the mountain. It is made of special materials, neither steel nor wood. It looks like the bones of some large animals. Only stainless steel parts are used at the joints.

Fortunately, they didn't come out too late, even though it was almost dusk, it wasn't so dark that they couldn't see anything.

The water in the sluice is still rushing out, rushing violently into the pool full of various mutant aquatic plants.

The water quality here is not as clear as in the cave. The washed out magnetic fluid and garbage are mixed with the underwater mud, making a mess of the water which is not considered clean at all.

In the center of the pool there is a giant plant emitting a faint blue light.It looks like an ancient tree that has grown for a hundred years, but it is weird without any leaves, and it looks like some kind of woody animal.

The trunk part is bulging into a bulb, and the web-like vines are wrapped around the glowing tissue in the center.Like a living thing, it expands and shrinks regularly like human lungs.

The blue light emitted by plants is a great temptation for insects, and it is almost surrounded by large mutant insects.When insects get too close, they will be paralyzed by the smell of this plant, fall into the pool and drown, becoming nutrients that the plant can absorb.

Can't help but sigh secretly, thanks to the presence of this plant, they didn't become the target of insects.

Out of the pool is a jungle full of vegetation and shrubs.Looking back, behind the jungle at dusk, there is actually the town drawn on the mural.Just like the towns they lived in, the high walls of the buildings were built around the Fourth Goddess Pillar in a circular shape.

He couldn't describe how he felt seeing the town at this moment.This place, which is no less than the size of their town, has long been a mess.

There are no living humans, dilapidated towns that have collapsed into wasteland, and only ruins and walls remain, dead silence.

Yu Ling:

Thank you for the fish food that Wu Qiong cutie sent last night!

Thinking about Gu Li's shape wrapped in magnetic fluid, it should be a bit like "Venom" in human form.

Don't worry about emotional interaction, the word count in this chapter is a bit overwhelming, so I put down the chapter and write it! (*/ω＼*) In addition, Gu Li is about to unlock a new skill.
