The villain also has spring

The area of ​​the swamp was so large that Wu Chen didn't remember that there was a lake nearby.After comparing the TT40 with the old map, it is also confirmed that there is no one nearby.Such a large area of ​​water...

Even if the water pipe breaks, it won't flow out of such a large swamp.

Subway plumbing.

Perhaps a subway tunnel somewhere was damaged, causing a plumbing.The ground full of ruins and scabbed by the fire dragon has no place to drain, and over time, this swamp has been formed.Of course, it doesn't rule out that the water lizard blocked the drain and created this rare habitat for itself.

In any case, Wu Chen has to finish the task.

Jiaochangkou is the starting point of Line 2, most of which have been soaked in water, and the shells of the surrounding landmark buildings have also been burned to charcoal ash. After comparison, TT40 gives the approximate orientation of the subway entrance .

Cybertronians are waterproof.Dog meat is no exception.Whether it's diving into the sea to rescue Megatron or the slow rise of Imprisonment from the water, it's shown that Cybertronians are waterproof.

The ruins of various buildings were piled up under the water surface, in different shades. After the dog meat scanned, the underwater topographic map was quickly obtained.

Stepping on the solid ruins as much as possible, wading to the target point.Many times, Wu Chen's cockpit wiped the water surface, and when the dog's head plunged into the water, the cockpit became a veritable submarine.As expected of a pod made according to the submarine level, it is not only waterproof, but the built-in air filter even begins to release the oxygen stored in the air tank to replace the carbon dioxide exhaled by Wu Chen.

In fact, Wu Chen's reproductive equipment has a perfect filtering function.Even if it is not supplemented, the high-pressure oxygen stored in the metal cells is enough to support Wu Chen's breathing for several hours.

Soon, Wu Chen saw the abandoned Line 2 train submerged underwater.Dog meat did not find the proper entrance of the subway, but went directly into the subway tunnel from a section of collapsed road.

The direction of the water flow also confirmed the judgment of the subway piping.

Gathering the maps of Shiba Ladder, TT40 quickly determined the approximate position of the exhaust vent.

Has anyone ever seen a radar glow like a searchlight?of course not.Therefore, with the help of dog meat's high-tech radar, without turning on the headlights of the pod, the internal structure of the entire subway tunnel is clearly displayed on the LCD screen in front of the cockpit.

Cybertronians breathe to cool down.When you enter the water, you don't need to breathe.Because the air cooling has become a more powerful water cooling!

Dog meat is never a choking hazard.

Stepping on the roof of the scrapped subway, Gou Rou quietly raised his head out of the water.

Just like an empty glass standing upside down in water will not be filled with water, because of the air pressure, this section of the subway tunnel is still partially not soaked by water.And as the dog meat gradually approached the smoke vent, the water level began to drop.The temperature also began to rise, and TT40 tried to detect the air.The concentration of carbon dioxide was found to be very high.The solubility of carbon dioxide in water is very small, but it is soluble in water.Like cola soda that you usually drink, when you open the bottle, gas comes out, which is carbon dioxide.

"Master, I seem to know the reason." TT40 said suddenly.

"What?" Wu Chen, who was engrossed in staring at the eggs that appeared on the screen, didn't react.

"Air pressure and water pressure." TT40 explained: "Because of the sealing of this long subway tunnel, the exhaust gas from the exhaust pipe of the power plant needs to push out a large amount of accumulated water to escape into the air. Maybe there was not so much water accumulated before. Or there are some openings in the roof of the tunnel where the exhaust fumes can escape..."

Wu Chen understood.This is the same as blowing bubbles with a straw.If it is an open water surface, such as a cup or a water basin, if you blow it with a straw, the bubbles will easily pop out.If it is a closed container, such as covering the mouth of the cup with your hand, it will be difficult to blow it again.Because the air in the cup cannot be discharged, a large air pressure is formed.

When the dog meat walked up the dry ground along the steps, Wu Chen finally saw the huge exhaust pipe and a nest of huge lizard eggs.

The lizard eggs are covered with thick mud, like huge preserved eggs.The mud that has been baked into hard scabs by the high-temperature exhaust gas is like a natural cotton coat and armor, protecting the hatching lizards inside.

Wu Chen couldn't help but lament the greatness of maternal love.Previous females would gobble up steel to protect their hatchling eggs.And this water lizard mother used thick mud to build a thick layer of armor for her cubs.However, just like the surface of the eggshell of an egg, there are many small holes that can pass through air and will not hinder the breathing of the embryo inside the egg.This thick layer of mud also has a lot of cracks.

This is a wonderful principle of nature.Just like the bottom of a dry pond and dry farmland, there will be many cracks.

40% of the soil is water, and water can "glue" the soil together very well.When a large amount of soil moisture evaporates, there is no water bonding and the surface expands with heat and contracts with cold, so cracks will appear.When it is dry, the surface soil loses more water, and the tension is lower than that of the bottom soil layer, which is cracked under the combined action of gravity and bottom tension.

The 'bottom' here is replaced by the surface of the lizard eggshell.

In this way, it is reasonable for the water lizard to choose this place to hatch its eggs.The high-temperature exhaust gas produced by the combustion of natural gas not only provides the temperature required for hatching, but also provides a sufficient heat source for baking this thick layer of clay armor.

Of course, the function of the mud shell is not only protection, but also heat preservation.

However, the female lizard made a fatal mistake.Little did she know that the exhaust was not the air she breathed every day, but deadly carbon dioxide.This is the difference between intelligent creatures and advanced intelligent life.The result was fatal.Fortunately, after scanning the dog meat, it was found that the embryo still had signs of life.In addition to the stronger vitality after the mutation, the fact that the female lizard has only recently nested here is also an important reason.

And the 'skylight' blocked by the female lizard is on the top of the mud nest.

No wonder, if the skylight above is not blocked, the waste will be discharged directly to the ground from here, and will not be deposited in the subway tunnel to compete with the stagnant water.

"Open?" TT40 asked.

"It definitely won't work." There must be a reason for the female lizard to block it.The skylight is open, and the heat passes quickly. If the temperature is not enough, it is likely to affect the hatching.This is pulling hatred.

"Master, the dog meat scanned the temperature at the core of the lizard egg, and it is not as high as the outside world. The temperature of the space we are in is already as high as 56°C, and the temperature at the core of the lizard egg is less than 30°C."

Looking at the ventilation ducts of the subway hanging high on the top of the tunnel, Wu Chen immediately said, "See if we can change the route."

"What does the master mean?"

"Connect the exhaust port into the ventilation pipe, then put a section of the ventilation pipe close to the eggs, and then connect it to the ground..." Wu Chen talked a lot, but was summed up by TT40 in one sentence.

"Put a radiator on the egg?"

"That's right!" The function of the radiator is to collect the heat diffused into the entire underground space. Although the heat is discharged, the temperature around the lizard's nest will not drop because the heat circulates continuously in the pipes.A more important function is to retain only heat energy and remove toxicity.

In this way, not only the temperature required for hatching lizard eggs is guaranteed, but also the waste is ensured to be discharged in time.Kill two birds with one stone.

Just do it. TT40 has calculated the air flow of the exhaust port and the temperature loss of the pipeline in detail, and a simple and accurate design method will be released soon.Let the robot dog release sound waves, and after confirming that the ventilation pipes above the head are still unblocked, the transformation will start soon.

Using laser eyes, the robot dog intercepted the abandoned iron pipes piece by piece from the original direction, and then transported them back to the high platform where the lizards nested.Then surround the lizard nest, form a pipe wall in circles, and finally bend upwards along the wall to connect to the still unobstructed ventilation pipe.

When it was connected to the exhaust pipe of the Eighteenth Ladder, the high-temperature exhaust gas immediately passed through the pipeline, circled around the lizard nest, spiraled upward, entered the old ventilation pipe of the subway, and was successfully discharged.

After testing, it was found that TT40 fully meets the hatching requirements of lizard eggs.

The cutting and welding of the pipeline depends entirely on the dog's cyclops.Otherwise, Wu Chen wouldn't be able to achieve the platinum evaluation of task completion.

The reason is very simple. To solve the problem of smoke exhaust, in fact, you only need to blow up the skylight blocked by the female lizard again.However, the heat is lost quickly, and the lizard eggs will likely stop developing.Not only would the little lizards be unable to hatch, but it would also arouse the hatred of the female lizard, making it almost impossible to recruit her.

As a technical geek who pursues perfect memory synchronization with the collection of all elements and zero death, an S-level evaluation is the minimum requirement.Generally, homeboys do tasks, pick up beans when they pick up beans, kill someone when they kill someone, do whatever the task is, and only pursue the speed of customs clearance, so in the eyes of technical geeks, this is not called playing games, but being led by the game nose play.

Opening up the world and MOD is a must for tech nerds.

Referring to the motivation of friar lizards to close the underground parking lot, it seems that the female lizards rarely return after they have built their nests.This may be in line with their natural habits.As the air pressure dropped, the water surface echoed slightly.However, it is still far away from the high platform where the lizard nests. Judging from the previous water level, there are still 4 or 5 steps away from the high platform, and there will be no problem with the lizard eggs.

After finishing all this, Gou Rou returned the same way with Wu Chen on his back.Before rushing out of the tunnel's fracture, the unexplained vibration started without warning. TT40 determined the approximate location of the source by collecting shock waves.It is at the original position of the big disc at the entrance of Jiaochang.There is also the central area of ​​the entire swamp.

The dead dog halo opened silently.Wu Chen thought for a while and said, "Go and have a look."

Dog Meat dived into the swamp, stepped on the ruins of buildings submerged under the water, and rushed towards the source of the earthquake.

From a distance, Wu Chen saw a huge upright green lizard. After TT40 scanning, it is judged that it is a variant of Chinese water dragon.However, the Chinese water dragon in Wu Chen's impression should be very docile.But now, this behemoth that ran wild was holding pieces of reinforced concrete that had been dismantled from the nearby buildings, and smashed it hard into the water not far away.Arouse monstrous waves!

The huge concrete blocks thrown by the female lizard like cannonballs were completely killed by the siege trebuchet!

Even a strong castle can fall apart!

The ruins of a nearby building were unfortunately hit by a boulder, and it collapsed as a whole with a bang!

Wu Chen also finally saw the giant that was previously covered by the building.That was clearly a gigantic crocodile!

No wonder the wife of the leader of the museum survivors said that the underwater city of the Three Gorges was destroyed by a group of huge crocodiles.Now, Wu Chen finally understood what a huge crocodile it was!
