Chapter 378

The activity amount around the small oasis of Castanea mollissima is no different from that in the barren zone.

However, the surrounding vegetation is still luxuriant, with low activity, which does not affect the growth of plants, but can not breed new plants except iron fruit.

Fire fragments can release special fire energy, catalyze metal corrosion into activity, and catalyze the reproduction of common golden fruits.

It's very strange.

It's just that for the time being, the laboratory in the eastern theater can't control this energy, and it's not even clear.

From the bottom up, the first barrier lake.

When he reaches the lake, Shen Cong slowly reaches into the lake. The sky eye opens, and the active wave begins to vibrate at a special frequency and quickly diffuses in the lake.

Waves travel very fast.

In a moment, the lake became a vivid black-and-white effect, three-dimensional picture in Shen Cong's mind. Although we can't see the color yet, as long as we see the appearance of the fish and shrimp, we can feel what color they should be.

It's a vision of mystery.

"There is no pearl mussel, there is a big fish, like the black fish mutation, probably the overlord of this lake, not too big, at most 1H talent, can't bite through my hell planting outfit."

"It's a little strange that this big black fish seems to be out of his mind and has a weak feeling Is it because the number of small fish in this lake is too small and food is scarce? It's possible that I've taken the pieces of the fire. It's decaying. The biomass is slowing down. It's impossible to maintain the food chain. "

A starving black fish, Shen Cong, can't even threaten him.

Immediately, he took the crab sword and slowly walked into the lake. He was ready to lead the big black fish to the lake and kill it. Then he was relieved to familiarize himself with the nature of water here.

He can swim, necessary survival skills, but not proficient.

The old drivers who drive are terrestrial creatures. Who would like to swim in the water with nothing to do.

Seeing Shen Cong in the water, the four legged dragon, who was watching the reflection of the water quaking curiously on the bank, immediately uttered a "chirping" cry, meaning to let Shen Cong come back.

"When you play on the shore, remember to watch King Kong." Shen Cong said to the four legged dragon and continued to go into the water.

"Bobo..." The quadruped screamed with the active wave.

Seeing Shen Cong ignore himself, he gets angry. He swings his tail and slaps it on the water to see how high the splash is. And then they twirl and jump, and I don't know what to think about on the shore. Put out the paw, want to go into the water, but after reaching in, quickly take out.

The water was deep and dangerous.

When Shen Cong has completely entered the lake and can't see the top of his head, the four legged dragon suddenly sends out a shrill cry, trying to get Shen Cong out, but there is no response.

The quadruped looked at the lake, green and deep.

Instinctive fear, jumping on the bank, finally emboldened, suddenly put his head into the lake. At the next moment, the four legged dragons discovered the new world. The lake below the surface was not dim. Instead, it glittering and glittering. It could see clearly that Shen Cong was walking towards the center of the lake.

Shen Cong can hold his breath for at least five minutes.

"Bobo..." The quadruped called again with the active wave.

Shen Cong looks back.

The four legged dragon immediately opened his mouth happily and was ready to shout. As a result, he choked down his saliva, threw his head out of the lake with a sudden crash, and coughed continuously on the bank.

By the time it recovered and didn't know if it should continue to go into the water, Shen Cong had already surfaced to breathe.

At the same time, the hungry big black fish, excited to see the new world, rushed directly over and opened its mouth to bite Shen Cong.

Shen Cong keeps a close eye on the big black fish. His hellish plant has extended out of the structure of flippers. Although he is not very proficient in using it, at least it can not be turned into a problem.

Facing the big black fish is a knife. The big black fish is very flexible. He dodges and bites Shen Cong's waist and abdomen. He wants to swallow Shen Cong.

"Great, my brother." Being bitten by a big black fish, Shen Cong is a little embarrassed.

Shen Cong can't even control the speed of the big black fish in the water.

However, because of the strength of the hell planting device, the big black fish can't bite its teeth even if it's broken.

In addition, Shen Cong's size is not small after wearing the hell planting outfit. He can't swallow it at one bite. He can only drag Shen Cong to drown him, which shows that this black fish still has some intelligence quotient.

Shen Cong didn't give it a chance.

Both hands suddenly grasp the big black fish mouth root, and then force a tear, hiss.

Shen Cong tore off the chin of the big black fish, and the blood dyed the lake red. Some small fish and shrimps came to eat crazily. Poor big black fish was starved and half dead, plus Sicong's heavy damage, killed on the spot. The overlord of the dammed lake is reduced to the food of small fish and shrimp that he disdains to eat

After Shen Cong released the pressure, all the fish and shrimp hid on the other side of the barrier lake, and even jumped to the shore crazily.Then, Shen Cong slowly became familiar with the nature of water and experimented with how to change the shape of hell's plant pack to make it more suitable for swimming and underwater combat.

One practice is a day and a night.

For Shen Cong, there is no feeling. For a post about the end of the world, he can refit the chariot for six years. His patience and perseverance are undoubtedly powerful.

The four legged dragon was not so patient. After choking a few saliva, he resolutely stopped going into the water. He ran all over the mountain, catching insects and digging pits to eat fruit.

Without Shen Cong's restraint, he was very happy.

The next morning, Shen Cong came to the dammed lake again and continued to adapt to underwater fighting.

After a long time.

Wow, Shen Cong comes up from the water and takes a deep breath for a change of breath.

Look at your watch. It's five past ten.

He has been practicing underwater for four hours.

Swim to the shore and start to sit down and eat some food to replenish your strength. At the same time, he can think about many problems in practice. The biggest problem is that he can't persist underwater for a long time. At present, he can only persist for five minutes, so he has to breathe. When the consumption is high, it takes three minutes to breathe.

"If only I could breathe directly in the water."

Shen Cong frowned and was not satisfied with being able to stay underwater for a long time.

He thought of two solutions. One was to bring his own oxygen bottle, or even seal the hell plant, and then fill it with air. When it was used up, he would go out to exchange air.

The other is to study a kind of respirator which is similar to the gill of a fish to ensure that it can breathe underwater.

"The oxygen content of a body of water is one fifth of the oxygen content of a volume of air. It can't keep up with the consumption of fish gills alone."

"If you can invent a device that can quickly separate oxygen from water, and then add it into a sealed hell plant, you can make full use of the oxygen in the water and replenish your own consumption. But what equipment should be used to separate oxygen? "

Shen Cong recalled a news report he had seen when he knew about survival equipment.

This is a Korean design photography. It designs an artificial fish gill called Triton. It is very small, about the size of two bicycle handles stuck together. The oxygen is filtered through the membrane on the handlebars, and then supplied with oxygen through the micro compressor in the middle. In theory, you can breathe for 45 minutes at a depth of 4.5 meters.

So the designers launched crowdfunding to raise funds to start production.

But eventually, he was beaten to pieces by the anti-counterfeiters. Triton's design was just bullshit. Water molecules are smaller than oxygen molecules. What kind of filter membrane can filter out oxygen. Even after screening, the oxygen content in the water is very low, and it takes 100 times the volume of water to produce a breath.

It's not feasible.

when Shen Cong thought of this design, he thought that the concept could be transplanted to his hell planting device. Adding an oxygen separation machine to the hell plant can make Triton large-scale. Instead of relying on the unreliable filter membrane, we can separate enough air for ourselves to breathe by reducing the pressure.

"Try it!"

Immediately, Shen Cong gave up training and went back to the King Kong.

Started to design their own artificial gills. (to be continued. )
