The amount of activity around the small yellow chestnut oasis is no longer much different from that in the barren zone.
However, the surrounding vegetation is still lush and the activity level is low, which does not affect the growth of plants, but it is unable to breed new plants except iron fruits.
Fire fragments can release special fire energy, catalyze metal corrosion to become active, and can also catalyze ordinary golden fruits to have the ability to reproduce.
Very peculiar.
It's just that for the time being, the laboratories in the eastern theater are not yet able to control this energy, and they haven't even scratched the surface of it yet.
From bottom to top, the first barrier lake.
Walking to the lake, Shen Cong slowly stretched his hand into the lake water, opened his eyes, and the active wave began to oscillate at a special frequency, quickly spreading in the lake water.
Waves propagate very fast.
In an instant, the entire lake became a vivid black and white effect in Shen Cong's mind, a three-dimensional picture. It was clear and vivid. Although the color could not be seen yet, as long as he saw the appearance of the fish and shrimp, he could feel it. , what color they should be.
This is a mysterious vision.
"There is no pearl clam, but there is a big fish, like a mutated black fish. It is probably the overlord of this lake. It's not that big. It only has 1 hour of talent. It can't bite through my hell plant equipment."
"It's a bit strange. This big black fish seems to be mentally disturbed and has a feeling of weakness... Is it because there are too few small fish in this lake and there is a lack of food? It is possible that the fire fragments were taken away by me. This place has declined and the number of organisms has declined. Slowed down, unable to maintain the food chain."
A half-starved black fish is not even a threat to Shen Cong.
Immediately, he carried the crab knife and slowly walked into the lake, preparing to lure the big black fish over, kill it, and then get familiar with the water in peace.
He can swim, a necessary survival skill, but he is not skilled in it.
The veteran driver is a terrestrial creature. Who would like to swim in the water without doing anything?
Seeing Shen Cong entering the water, the four-legged dragon on the shore curiously looked at the trembling reflection in the water, and immediately let out a "chi-chi-coo-coo" cry, meaning to ask Shen Cong to come back.
"When you play on the shore, remember to watch Donkey Kong." Shen Cong ordered the four-legged dragon and continued to enter the water.
"Bobo..." The four-legged dragon called out with active waves.
Seeing that Shen Cong ignored him, he was a little angry. He swung his tail and hit the water with a splash, making the water splash high. Then he jumped around again, wondering what he was thinking about on the shore. He stretched out his paws and wanted to He went into the water, but after putting it in, he quickly took it out.
The lake water is dark in color and looks dangerous.
When Shen Cong had completely entered the lake and could no longer see the top of his head, the four-legged dragon suddenly let out a sharp "chichichi" cry, trying to get Shen Cong to come out, but there was no response.
The four-legged dragon looked at the gradually calming lake surface, which was green and deep.
Instinctively afraid, he jumped around on the shore, and finally got the courage to put his head into the lake. The next moment, the four-legged dragon discovered a new world. The lake below the water surface was not dim, but on the contrary, it was shining brightly. It can be clearly seen that Shen Cong is walking towards the center of the lake.
Shen Cong could hold his breath for at least five minutes.
"Bobo..." The four-legged dragon shouted again with active waves.
Shen Cong turned his head.
The four-legged dragon suddenly opened its mouth happily and was about to scream, but choked on a mouthful of water, threw its head out of the lake with a sudden splash, and kept coughing on the shore.
By the time it regained its breath and wondered whether it should continue to enter the water, Shen Cong had already surfaced for air.
At the same time, the half-starved big black fish was as excited as seeing the new world and rushed over, opening its big mouth to bite Shen Cong.
Shen Cong watched the big black fish closely. His hell plant equipment had extended a flipper-like structure. Although he was not very proficient in using it, at least steering would not be a problem.
The big black fish was facing the big black fish with a knife. The big black fish was very flexible and dodged. It opened its mouth and bit Shen Cong's waist and abdomen, trying to swallow Shen Cong in one bite.
"That's awesome, my brother." Shen Cong was a little embarrassed when he was bitten by the big black fish.
On land, Shen Cong could crush the big black fish to death with his head, speed and impact, but in the water, he couldn't even control his balance, let alone kill the big black fish.
However, the strength of the hell plant equipment is such that the big black fish can't bite it even if its teeth are broken.
In addition, the size of Shen Cong after wearing the hell plant suit was not small, and it could not swallow it in one bite, so it could only drag Shen Cong in an attempt to drown him, which shows that this black fish still has some intelligence.
Shen Cong didn't give it a chance.
He suddenly grabbed the base of the big black fish's mouth with both hands, and then tore it apart hard, making it hiss.
The big black fish's jaw was torn off by Shen Cong, and the blood stained the lake water red. Some small fish and shrimps rushed in to eat. The poor big black fish was half starved to death, and due to Sicong's severe injuries, he died on the spot. The mighty overlord of the barrier lake has become the food of the small fish and shrimps that he disdains to eat.
…
After clearing out the big black fish, there was no longer any threat to this barrier lake. After Shen Cong released the pressure, all the fish and shrimps hid on the other side of the barrier lake, and even jumped to the shore crazily.
Then, Shen Cong slowly became familiar with the properties of water here, and experimented with how to change the form of the hell plant to be more suitable for swimming and underwater combat.
One practice lasts a day and a night.
This is nothing to Shen Cong. He can modify his tank for six years just for a post about the end of the world. His patience and perseverance are definitely powerful.
The four-legged dragon was not so patient. After choking on a few mouthfuls of water, he decided not to go into the water anymore and ran all over the mountain with his legs, catching insects and digging holes to find fruits to eat.
Without Shen Cong's restraint, it was very happy.
Early the next morning, Shen Cong came to the barrier lake again and continued to adapt to underwater fighting.
After a long time.
Suddenly, Shen Cong came up from the water and took a deep breath.
I looked at my watch, it was ten minutes past five.
He has been practicing underwater for four hours.
Swim to the shore, sit down and eat some food to replenish his strength. At the same time, he thinks about the many problems that arise during the practice. The biggest problem is that he cannot persist underwater for a long time. Currently, he can only persist for five minutes before he needs to ventilate. .When consumption is high, you need to take a breath every three minutes.
"It would be nice if I could breathe directly in the water."
Shen Cong frowned, dissatisfied that he couldn't stay underwater for a long time.
There are two solutions he came up with. One is to bring his own oxygen bottle, or even completely seal the hell plant, and then fill it with air. When it is used up, he can go out for air.
The other is to research a respirator similar to fish gills to ensure that you can breathe underwater.
"The oxygen content of a volume of water is one-fifth of the oxygen content of a volume of air. Simply relying on fish gills to breathe still cannot keep up with consumption."
"If you can invent a device that can quickly separate oxygen from water, and then add it to the sealed hell plant, you can make full use of the oxygen in the water to supplement your own consumption. But what equipment should be used to separate the oxygen?"
Shen Cong remembered a news report he had seen when he was learning about survival equipment.
It’s a Korean design photoshoot. They designed an artificial fish gill called T-riton. It is very small, about the size of two bicycle handles glued together. It filters oxygen through the filter membrane on the handle, and then through the micron in the middle. The compressor supplies oxygen. Theoretically, it can breathe underwater in 4.5 meters of water for 45 minutes.
So the designer launched a crowdfunding campaign to raise funds to start a production company.
But in the end, they were beaten to pieces by anti-counterfeiters. T-Dayton is simply a nonsense design. Water molecules are smaller than oxygen molecules. What kind of filter membrane can filter out oxygen? Even if it is filtered out, the oxygen content in the water is very low. It takes a while. It takes a hundred times the volume of water to produce one breath.
Totally 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 enlarge the t-dayton, without the unreliable filter membrane. Instead, it separates enough air for yourself to breathe by reducing the blood pressure.
“Give it a try!”
Immediately, Shen Cong gave up continuing training and returned directly to Donkey Kong.
Start designing your own artificial fish gills. (To be continued.)
