Heavy Armoured Truck In Post-apocalyptic World
Chapter 378: Artificial Fish Gills
The amount of activity around the small oasis of yellow chestnut trees is not much different from that in the barren zone.
However, the surrounding vegetation is still lush, and the activity is low, which does not affect the growth of plants, but it cannot breed new plants other than iron fruits.
The tinder fragments can release special tinder energy, catalyze the corrosion of metals 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 haven't been able to control this energy, and haven't even figured out the fur.
From bottom to top, the first barrier lake.
Walking to the edge of the lake, Shen Cong slowly stretched his hand into the lake water, the sky eyes opened, and the active wave began to oscillate at a special frequency, quickly spreading in the lake water.
Waves travel very fast.
In an instant, the entire lake became a vivid black and white, three-dimensional picture scroll in Shen Cong's mind. It is clear and vivid, although the color cannot be seen yet, but as long as you see the appearance of those fish and shrimp, you can feel what color they should be.
It is a vision tinged with mystery.
There are no pearl oysters, but there is a big fish, like a mutated black fish, probably the overlord of this lake, and it's not too big, with at most 1h talent, it can't bite through my hell plant outfit.
It's a little strange, this big black fish seems to be out of spirits, feeling weak... Is it because the number of small fish in this lake is too small, and the food is scarce? It is possible that I took the fire fragments. This place has decayed, and the number of creatures Slow down, unable to maintain the food chain.
For Shen Cong, a big black fish that was half-starved was not even a threat.
Immediately, he carried the Asahi Crab Broadsword and slowly walked into the lake, preparing to lure the big black fish over, kill them, and then feel at ease here to familiarize himself with the water.
He can swim, a necessary survival skill, but not proficiently.
The old driver who drives is a land creature, who would like to swim in the water without doing anything.
Seeing Shen Cong go into the water, the four-legged dragon curiously looking at the trembling reflection on the water surface on the bank, immediately let out a chee-chee-coo-coo sound, which meant to let Shen Cong come back.
You are playing on the shore, remember to watch the King Kong. Shen Cong gave instructions to the four-legged dragon, and continued to enter the water.
*... The four-legged dragon screamed with an active wave.
Seeing that Shen Cong ignored him, he got a little angry, flicked his tail, and hit the water with a slap, splashing the water so high. Then he twisted and jumped again, wondering what to do on the shore. He stretched out his claws, wanting to get into the water, but after reaching in, he quickly took them out again.
The lake 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 chirp chirp, trying to get Shen Cong out, but there was no response.
The four-legged dragon looked at the calming lake, green and deep.
Instinctively afraid, he jumped up and down on the shore, and finally bravely stuck his head into the lake. The next moment, the four-legged dragon discovered Xintiandi. The lake below the water surface was not dim. On the contrary, it was shining brightly. 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.
*... The four-legged dragon shouted again with an active wave.
Shen Cong turned his head.
The four-legged dragon immediately opened its mouth happily and was about to shout, but choked on a mouthful of water, threw its head out of the lake with a loud splash, and coughed non-stop on the bank.
When it regained its breath and wondered whether it should continue to enter the water, Shen Cong had already surfaced to take a breath.
At the same time, the big black fish, which was half-starved, was as excited to see the New World, and rushed over, opening its mouth wide to bite Shen Cong.
Shen Cong watched the big black fish closely. His hell plant suit had already extended into a flipper-like structure. Although he was not very proficient in using it, at least turning was not a problem.
Facing the big black fish is a knife,
The big black fish was very nimble, dodging away, opened its mouth and bit Shen Cong's waist and abdomen, trying to swallow Shen Cong in one gulp.
That's amazing, my brother. Shen Cong was a little embarrassed to be bitten by the big black fish.
On land, with the size, speed and impact of the big black fish, Shen Cong could trample to death with one foot, but in the water, he couldn't even control his balance, let alone kill the big black fish.
However, with the strength of the hell plant, the big black fish would not be able to gnaw even if its mouth was full of teeth.
In addition, Shen Cong's size after wearing the hell plant costume was not small, it couldn't swallow it in one gulp, so it could only drag Shen Cong, trying to drown Shen Cong, which showed that this black fish still had some IQ.
Shen Cong didn't give it a chance.
Both hands suddenly grabbed the base of the big black fish's mouth, then tore it hard, hissing.
The big black fish's jaw was torn off by Shen Cong. The lake was stained red with blood, and some small fish and shrimp frantically came to eat it. The poor big black fish was already half starved to death, and with Sicong's serious injury, he died on the spot. The overlord of the barrier lake has become a food for the small fish and shrimps that he disdains to eat
...
After clearing the big black fish, there was no threat in this barrier lake. After Shen Cong let go of the pressure, all the fish and shrimp hid on the other side of the barrier lake, and even jumped wildly to the shore.
Then, here, Shen Cong gradually became familiar with the nature of the water, and experimented with how to change the shape of the hell plant suit, making it more suitable for swimming and underwater combat.
One practice is one day and one night.
To Shen Cong, this didn't make much sense. For a post about the end of the world, he could modify the tank for six years. His patience and perseverance were undoubtedly powerful.
The four-legged dragon was not so patient anymore. After choking on a few sips of water, he resolutely stopped going into the water, let go of his feet and ran all over the mountain, catching insects and digging pits to find fruit to eat.
Without Shen Cong's restraint, it was very happy.
Early the next morning, Shen Cong came to the barrier lake again to continue adapting to underwater combat.
after a long time.
Wow, Shen Cong floated up from the water, took a deep breath in exchange.
I looked at my watch, it was ten past five.
He has been practicing underwater for four hours.
Swim to the shore and start to sit down and eat some food to replenish my strength. At the same time, he was thinking about the many problems that arose during the practice. The biggest problem was that he could not persist underwater for a long time. He could only persist for five minutes at present and had to take a breath. When the consumption is high, you have to take a breath every three minutes.
It would be nice to be able to breathe directly in the water.
Shen Cong frowned, dissatisfied with not being able to stay underwater for a long time.
He thought of two solutions, one is to bring your own oxygen cylinder, or even seal the hell plant completely, and then fill it with air, and then go out to take a breath when it is exhausted.
The other is to study a respirator similar to fish gills to ensure that it 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 the consumption.
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 and supplement your own consumption. But what device should you use to separate oxygen?
Shen Cong remembered a news report he had seen when he learned about survival equipment.
It’s about South Korea’s design photo. They designed an artificial fish gills, which are very small, about the size of two bicycle handlebars glued together. Oxygen is filtered through the filter membrane on the handlebars, and then supplied by a micro compressor in the middle. oxygen. In theory, it can breathe underwater for 45 minutes in waters as deep as 4.5 meters.
So the designer initiated crowdfunding to raise funds to start a company for production.
But in the end, it was a nonsense design that was beaten to pieces by the anti-counterfeiters. Water molecules are smaller than oxygen molecules. What kind of filter membrane can filter out oxygen. Even if filtered out, the oxygen content in the water is very low, and it takes a hundred times the volume of water to produce a breath.
totally unfeasible,
When Shen Cong thought of this design, he mainly thought that this concept could be transplanted to his hell plant. Adding an oxygen separation machine to the hell plant can completely enlarge the size, put aside the unreliable filter membrane, and separate a sufficient amount of air by reducing the pressure for self-breathing.
Try it!
Immediately, Shen Cong gave up training and went straight back to the King Kong.
Start to design your own artificial fish gills.
