Pull oxygen tank, this is an underwater breathing apparatus designed by Shen Cong after thinking for a long time. Pen % fun % Pavilion www.biquge.info

The working principle is very simple, using the tension generated by the swing of the arms and legs during swimming, transmitted through the tension rope and concentric gear set, driving the piston, and doing piston movement in the two cylinders on the back to reduce the pressure in the cylinder and supply the separated air into the inside of the hell plant.

Shen Cong's physical fitness is now difficult to calculate, and the vague standard of Niu Zhili is becoming more and more difficult to generalize, and if you have to define, it is about the quality of forty Niu Zhi.

Gestures can send out tons of force.

Even if the underwater resistance is very large, it is still difficult to limit Shen Cong's play, so it is completely possible to use artificial power to separate the air in the water and obtain oxygen.

There are two tension oxygen tanks, one on the left and one on the left and one on the left.

It belongs to the equipment that can be disassembled, and when it is not in use, take down the tension oxygen tank, and the tension rope of the arms and legs does not need to be disassembled, and it is not in the way.

It's very convenient to use.

"The final effect of the launch test is not good." In the evening, Shen Cong installed the tensile oxygen tank, the mask of the helmet was fully sealed, and jumped into the dammed lake.

When you get underwater, you swim immediately.

A little more paddling force than before can drive the piston in the tensile oxygen tank like a fly, and effectively start to depressurize and separate the air.

The separated gas, when pressed down by the piston movement, is pressed out of the separator and pressed into the inside of the hell plant.

After breathing, the exhaust gases are discharged from the snorkel on the other side.

After a whole set of processes, there is flowing water and moist air in the Hell Plant, the oxygen content is not high but not low, with the oxidation efficiency of Shen Cong's current blood gold state, it can fully provide what Shen Cong needs to consume.

It is important to know that the blood of ordinary people can only use breathing to enter a quarter of the oxygen into the lungs, and the remaining three-quarters is excreted with the carbon dioxide produced.

Shen Cong's body can use at least two-thirds of the oxygen.

He takes a breath several times more efficiently than others.

"It worked well, five minutes passed, I didn't feel the slightest lack of oxygen, and I could continue to train underwater." Shen Cong brandished the Asahi Crab Broadsword.

Swing your flippers with your legs to keep your body moving back and forth at the angle of the current.

The Asahi crab knife is constantly dancing, chopping, stabbing, blocking, picking, and various moves are used in turn. Shen Cong didn't know anything about martial arts routines, he had only practiced sanda and fighting before the end of the world, but now these routines are completely useless, evolution beasts are often tens of meters long, and no matter how exquisite the moves are, they are in vain.

Therefore, Shen Cong, who has a heart, is ready to sum up his experience in hunting evolution beasts and optimize his combat methods.

Create another fighting style.

What kind of way is lethal to the evolved beast, let's focus on practicing. Where you are weak, you will focus on training. It's the same underwater, how to twist your body, how to turn around, how to wield a big knife, how to slash better, you need to constantly explore and remember.

"Bobo ......"

As night fell, the four-legged dragon returned to the shore and slapped the water with its big tail to remind Shen Cong that it was time to go home.

Home is Donkey Kong.

A moment later, Shen Cong surfaced from the bottom of the lake, and then swam to the shore at a speed like a jet ski. Shook the water off his armor, opened the sealed mask, and exhaled a breath of turbidity. Then jump on top of the four-legged dragon's head, ride the dragon saddle, and touch the dragon spear hanging beside it.

Patting the four-legged dragon on the head: "Go back, little four." ”

"Gollum." The four-legged dragon immediately galloped between the mountains and rocks, as if walking on the ground.

After a while, he arrived at Fuxing Township, where Donkey Kong stopped, and the four-legged dragon hid in the big hole he dug to sleep, and Shen Cong took advantage of the fact that it was still early to continue his work at night.

The tensile oxygen tank was improved first.

"The depth of the dammed lake is 11 meters, the water pressure is not too large, I continued to train underwater for 1 hour and 21 minutes, and then I felt stuffy, the confined environment of hell planting, accumulated too much exhaust gas, and reached the limit of diving."

Opening the notebook, Shen Cong recorded the data of the tension oxygen tank.

At a depth of 15 meters, the tensile oxygen tank can work for at least one hour and twenty minutes with the Hell Plant.

"If I increase the capacity of the tensile oxygen tank, I can increase the dive time by at least another 30 minutes, but it doesn't make much sense, I don't need to cross the Bohai Bay or the Qiongzhou Strait, and I don't need to extend the working time. Once the capacity of the rally oxygen tank is increased, it will increase in volume, thus destroying the current warframe line. ”

"The work efficiency can be improved, but there is something wrong with the pulling system on the left, which is more laborious than the right one, which will affect my body balance and need to be modified."

……

The next day, February 14th.

There is no affection. Human affection. On People's Day, Shen Cong gave his dolls a big purge early in the morning, which was clean and new.

Dried in the sun and put away: "The clothes are not as good as new, and the people are not as good as the old, which is good." ”

The sun was shining in the sky and the dive continued.

The improved tensile oxygen tank makes Shen Cong's underwater movement smoother.

Today, I didn't continue my underwater training and started exploring the dammed lake. At present, there are still five dammed lakes waiting to be explored, Shen Cong is mainly looking for pearl mussels, the first mouth is not, the second mouth is still not, in the third mouth, finally found the pearl mussels, not many, like a small community.

The largest one is the size of a water tank.

After noticing Shen Cong, the pearl mussel immediately closed the shell tightly. However, in front of it, it was actually a humanoid beast, grabbing a crack in the shell of a mussel with both hands, and with explosive strength, it directly broke the shell of the pearl mussel.

Cut off a few live pearls inside.

Let go.

The pearl mussel immediately closed the shell, in fact, it did not suffer much damage, the live pearl is a burden for the pearl mussel, and taking it away is helping it.

In an hour, all pearl mussels and live pearls that were larger than the size of a basin were removed.

The number of packages packed before shipping is not much.

In the next two dammed lakes, there were no pearl mussels to live, and Shen Cong could only leave the small oasis of yellow chestnut trees with a few live pearls.

"It's better than nothing, and if I can, I should take some pearl mussel seedlings and throw them in other lakes. Without the shards of the tinder, the food chain here is becoming more and more fragile, and species can become extinct at any time. The Dongpu Reservoir and Dafangying Reservoir around Xinhefei are very suitable places for breeding, and Hongze Lake next to Huai'an City can also be put into aquaculture. ”

"I don't have time for this kind of thing, I can notify the war zone to do it, and live pearls don't need to be kept secret. The yogurt banyan tree and the old ginkgo tree do not need to be kept secret. When I leave, I need to let the people in the war zone manage it on my behalf, and maybe when I come back in the future, I can directly harvest resources. ”

When he was in the Eastern Theater of Operations, these materials belonged to Shen Cong's private property, but if he left, he would only cheapen the Evolution Beast.

It is better to leave it to human beings to manage, and even develop breeding and expand the scale.

Live pearls can stimulate the third development of the body, yogurt banyan trees can break the active locks of low-level evolved beasts such as insects, and silver fruits can make evolved beasts dizzy and sleepy after a sufficient amount of silver fruits, which is an upgraded and strengthened version of active peaches.

All have magical effects, but compared to Shen Cong, although these are strategic materials, the effect is actually a bit chicken.

Live pearls and yogurt banyan trees make pearl milk tea, and it is difficult to say whether it will work on his body, and most of it is basically used by him to feed King Kong ants and honey bees. These are his pets, and after Lv1-Pure Gold Era, the work efficiency will be more efficient.

The silver fruit is occasionally taken out to eat, and it is considered to be a pistachio, because the amount carried is not much, and I have never thought of using the silver fruit to hunt the evolution beast.

"If I collect a large amount of silver fruit and throw it away to lure the Iron Eater, or the Great Lynx and the Greenskin Frog, can I make these three Ultimate Gold Beasts dizzy and sleepy? With the number of fruits of the old ginkgo tree, it should be able to stun the ultimate golden beast? ”

Once the thought popped up, Shen Cong could no longer suppress his thoughts.

The Black Iron Giant Bear can be hit hard by Li Xunhuan, and then picked up beans by himself, now that he is super four talented, why can't he try to hunt the ultimate golden beast?

Thinking of this, Shen Cong's breathing couldn't help but increase a little.

"Whew, that's a bit exciting......" (To be continued.) )
