The amount of activity around the small oasis of the yellow chestnut tree is not much different from that of the barren zone. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

However, the surrounding vegetation is still lush, and the activity level is low, which does not affect the growth of plants, but it cannot breed new plants except for iron fruits.

Tinder fragments can release special fire energy, catalyze metal corrosion into activity, and can also catalyze the ability of ordinary golden fruits to reproduce.

Very peculiar.

It's just that for the time being, the laboratory in the Eastern Theater of Operations can't control this energy, and it hasn't even figured out the skin.

From the bottom up, the first dammed lake.

Walking to the lake, Shen Cong slowly put his hand into the lake water, the eye of the sky opened, and the active wave began to oscillate at a special frequency, quickly spreading in the lake water.

Waves travel at a fast speed.

In an instant, the entire lake, in Shen Cong's mind, became a vivid black and white effect, a three-dimensional picture. Clear and vivid, although you can't see the color yet, as long as you see the appearance of those fish and shrimp, it seems to be able to feel what color they should be.

It's a vision with a mystical tinge.

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

"It's a little strange, this big black fish seems to be mentally wrong, and it feels weak...... Is it because the lake has too few small fish and a lack of food? Chances are, the shards of the fire were taken by me, and it's decaying, the number of creatures slowing down, and the food chain is no longer sustainable. ”

A big black fish that is half starved to death, for Shen Cong, it can't even reach the threat.

Immediately, he carried the big knife of the crab and slowly walked into the lake, ready to lure the big black fish over and kill it, and then familiarize himself with the water here.

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

The old drivers who drive belong to the land creatures, who would like to swim in the water with nothing to do.

Seeing Shen Cong entering the water, the four-legged dragon who was curiously watching the trembling reflection on the water surface on the shore suddenly let out a "chirp" sound, which meant to let Shen Cong come back.

"You play on the shore and remember to watch Donkey Kong." Shen Cong commanded the four-legged dragon and continued to enter the water.

"Bobo......" the four-legged dragon called out with an active wave.

Seeing that Shen Cong ignored himself, he was a little angry, flicked his tail, and hit the water with a snap, splashing the water as high as it was. Then he squirmed and jumped again, not knowing what to ponder on the shore. He stretched out his claws and wanted to enter the water, but when he got in, he quickly took them out.

The water is dark and dangerous.

When Shen Cong had completely entered the lake and could not see the top of his head, the four-legged dragon suddenly let out a sharp cry of "chirp", wanting Shen Cong to come out, but there was no response.

The four-legged dragon looked at the lake that was gradually subsiding, green and deep.

Instinctively afraid, he jumped around on the shore, and finally he was brave enough to stick his head into the lake at once. The next moment, the four-legged dragon found Xintiandi, the lake below the water surface, not dim, on the contrary, the light was shining, it could clearly see that Shen Cong was walking towards the center of the lake.

Shen Cong held his breath for at least five minutes.

"Bobo......" the four-legged dragon shouted again with an active wave.

Shen Cong turned his head.

The four-legged dragon opened its mouth happily and was about to scream, but it choked on a mouthful of water, threw its head out of the lake with a bang, and coughed non-stop on the shore.

By the time it had recovered and didn't know whether to continue in the water, Shen Cong had already surfaced for a breath.

At the same time, the big black fish, which was half hungry to death, was as excited as he saw the new continent, and he rushed over directly, opening his mouth to bite Shen Cong.

Shen Cong watched the big black fish closely, his hell plant had extended to a web-like structure, although he was not very skilled in using it, at least it was not a problem to turn.

Facing the big black fish is a knife, the big black fish is very flexible, dodging away, opening its mouth to bite Shen Cong's waist and abdomen, wanting to swallow Shen Cong in one bite.

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

On land, with the head, speed and impact of the big black fish, Shen Cong can trample to death with one foot, but when he is in the water, he can't even control the balance, let alone kill the big black fish.

However, the strength of the hell plant, the big black fish can't bite even if it collapses with a full mouthful of teeth.

In addition, Shen Cong's size after putting on the Hell Plant Suit is not small, it can't swallow it in one bite, so it can only drag Shen Cong and want to drown Shen Cong, which shows that this black fish still has some IQ.

Shen Cong didn't give it a chance.

Both hands suddenly grabbed the root of the big black fish's mouth, and then tore it hard, hissing.

The jaw of the big black fish was directly torn off by Shen Cong, the blood stained the lake red, and some small fish and shrimp frantically rushed to eat. The poor big black fish was already half starved to death, and coupled with Sicong's heavy injury, he was killed on the spot. The overlord of the dammed lake has been reduced to the food of small fish and shrimp that he disdains to eat

……

After removing the big black fish, there was no longer the slightest threat to this dammed lake, and after Shen Cong let go of the coercion, all the fish and shrimp hid on the other side of the dammed lake, and even jumped to the shore frantically.

Then, Shen Cong slowly familiarized himself with the water here, and experimented with how to change the form of the Hell Plant, which was more suitable for swimming and underwater combat.

A practice is a day and a night.

This doesn't feel anything for Shen Cong, he can modify the chariot for six years for an apocalyptic post, patience and perseverance are definitely undoubtedly powerful.

The four-legged dragon was not so patient, and after choking on a few mouthfuls of water, he resolutely stopped going into the water, and spread his feet and ran all over the mountain, catching insects and digging pits to find fruit to eat.

Without Shen Cong's constraints, it was very happy.

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

After a long time.

With a bang, Shen Cong floated up from the water and took a deep breath.

I looked at my watch, and it was ten and five o'clock.

He has been practicing underwater for four hours.

Swim to the shore and start sitting down to eat some food and replenish your energy. At the same time, he thought about the many problems that arose during the exercises, the biggest of which was that he could not hold on to it underwater for a long time, and he could only hold on for five minutes at the moment, and he had to breathe. When consumption is high, you have to change your breath in three minutes.

"It would be nice to be able to breathe directly in the water."

Shen Cong frowned, very dissatisfied with not being able to stay underwater for a long time.

There are two solutions he can think of, one is to bring his own oxygen cylinder, or even seal the Hell plant completely, then fill it with air, and when it is gone, go out for ventilation.

The other is to study a respirator that resembles the gills of a fish and is guaranteed to breathe underwater.

"The oxygen content of a volume of water is one-fifth of the oxygen content of a volume of air, and it still can't keep up with the consumption by relying on the gills of fish to breathe."

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

Shen Cong remembered a news report he had seen when he was learning about survival equipment.

The Korean designer designed an artificial fish gills called Triton, which is very small, about the size of two bicycle handlebars glued together, filters oxygen through the filter membrane on the handlebar, and then supplies oxygen through a micro compressor in the middle. Theoretically, it is possible to breathe underwater for 45 minutes in water at a depth of 4.5 meters.

So the designer launched a crowdfunding campaign to raise funds to start a company for production.

But in the end, the body was beaten by the anti-counterfeiters, and Triton was simply a nonsense design, water molecules are smaller than oxygen molecules, and what filter membrane can be screened out of oxygen. Even when screened, the oxygen content in the water is very low, and a hundred times the volume of water is required to produce a breath.

Completely unfeasible,

Shen Cong thought of this design, mainly because he felt that this concept could be transplanted to his Hell Plant. Adding an oxygen separation machine to the Hell plant can completely make the Triton larger, leaving behind the unreliable filter membrane, and instead separating enough air by depressurizing it for it to breathe.

"Give it a try!"

Immediately, Shen Cong gave up continuing training and returned directly to Donkey Kong.

I started to design my own artificial gills. (To be continued.) )
