Lying on the ground, Tang Chen greedily breathed air.

He can't remember how many times he walked back and forth between the Dark River and the Cave, and he couldn't see the light of day for a long time in the cave, and he lacked an accurate idea of the passage of time. In addition to the necessary rest, he spent almost all his time in the dark river, and the sectional construction of the dark river channel has been carried out step by step.

These days, Tang Chen is like a diligent ant.

With the ventilation point as the point and the rattan rope as the line, the operation is segmented, and the ventilation points are connected one by one, and the scope of Tang Chen's control is gradually expanding. Up to now, he had advanced nearly three hundred meters downstream along the Dark River, and the previously refined rattan ropes in the Qiankun bag had long been exhausted, so that he had to leave the cave and recover all the rattan ropes of the Heavenly Ladder Road.

The segmented encroachment on the Dark River is progressing well.

It's hard work, but he's motivated, and everything he does is for his own safety, which takes a lot of time and energy, but minimizes the risk.

There are still a lot of rattan ropes recovered, but the encroachment on the dark river has come to an end.

At the very front of the area he can control now, the dark river trend suddenly went downward, and the entire section of the river was occupied by the river, Tang Chen connected the rattan rope to 60 meters and still couldn't find a new ventilation point. He didn't continue to lengthen the rope, 60 meters is his limit, beyond this distance, he may not have enough stamina to return in the countercurrent. In a closed environment, if he fails to return in time before his physical strength is exhausted, even if there is a gourd to provide him with oxygen to continue his life, it will still be difficult to escape the doom of drowning.

Tang Chen sighed: "It seems that the time for gambling has come......"

Little Tom stepped on an elegant catwalk, and Shi Shiran came to Tang Chen.

Seeing the kitten, a trace of warmth flashed in Tang Chen's eyes, and he said in a deep voice: "We can leave soon, but there may be danger, if you change your mind and don't want to leave, it's too late to regret it." ”

"Meow!"

"But you're afraid of water. ”

Tang Chen pointed at the kitten's death hole very inhumanely, it is the nature of cats to be afraid of water.

The kitten was visibly flustered.

But soon, it straightened its body and raised its tail in a majestic manner, telling Tang Chen that it could overcome difficulties.

"Looks like you really don't want to stay here. ”

Tang Chen smiled dumbly, and raised his thick eyebrows lightly: "Then it's decided, whether it's dead or alive, let's break together!"

"Meow!"

"We need to do a little bit more preparation, the water is very fast, we have to find a way to strengthen the protection, and there is also the problem of ventilation under water for a long time, I will figure out how to do this. You go catch worms, catch more, we have a good meal today, and from now on, we have to stock up on food. ”

"Meow!"

The problem of ventilation is very easy to solve, Tang Chen used to refine rattan ropes, a large number of gourds were thrown aside, waiting to be dried and burned as firewood, only a little processing, it was a natural underwater gas cylinder. If the number is not enough, just go to the cliff and walk around.

The issue of underwater protection made Tang Chen think a lot.

The dark river is turbulent, there are many curves, and the three hundred meters in front of the exploration are also tied with rattan ropes as insurance, and the road behind can only follow the waves, and the collision with the stone walls and reefs in the river will be very frequent. Exploring the dark river for 300 meters, Tang Chen was injured many times while wearing a safety rope, and there was no slowing down measure at all, and the impact of being pushed by the river would obviously be more frequent and more violent.

Tang Chen will refine some low-level magic weapons, but the premise is to have the right materials, now trapped in the desperate valley, it is difficult for the Qiao woman to cook without rice, he can only use the existing resources in the valley to find a way.

The valley has the most vine ropes and gourds.

Tang Chen tried to wrap a rattan rope all over his body, jumped over, and let the dark river take him away. After a while, he returned from the dark river with a disgraced face, and an extra bag on his forehead...... Facts have proved that the "rattan coat" can reduce the probability of skin trauma due to impact, but due to the lack of sufficient cushioning, the force of the impact is equivalent to directly transmitting to the body, and Tang Chen was quickly knocked to pieces.

Lack of buffering ......

Tang Chen returned to the valley and cut off a few fresh mountain vines full of gourds, and removed the leaves and vines, leaving only the vines and gourds. Carefully wrapped the new rattan around his body, a new-style rattan robe full of gourds was announced, and Tang Chen called it the "second generation of rattan clothes".

The performance of the second generation of rattan clothing is much better than that of the first generation, and the most obvious improvement is the buffer.

In the event of a collision, the outer gourd first comes into contact with the rock, and the impact of the gourd is transmitted to the rattan rope, and a part of the energy is taken away by the water current, thereby reducing the impact on the body. The role of the gourd is not just shock absorption, Tang Chen plans to deal with them all, and when necessary, directly unscrew the bottle mouth for ventilation.

Kill two birds with one stone!

However, after the test in the dark river, the protective power of the second generation of Fuji still could not satisfy Tang Chen.

Wearing the second generation of rattan clothes, he floated 200 meters in the dark river, and he was hit and dizzy and painful. Tang Chen didn't know where the dark river would take him, and it was difficult to predict how far he would need to drift in the dark river in the end, and half his life would be lost after two hundred meters of drifting, and hitting the dark river was tantamount to killing himself.

Tang Chen felt that he was very bitter.

In order to get something delicious, he didn't recruit anyone and didn't break the law, but he was unlucky to fall off the cliff and was almost overtaken by countless black beetles. I finally saw some hope of getting out of trouble, but I encountered a series of difficult problems, is my brother destined to be accompanied by insects in this valley? If one day the big cat of Little Tom's family comes back and takes Little Tom away, how can my brother live in this valley? Those black beetle shells are so hard that it is difficult to get something to eat......

Seems to have overlooked something.

Black Beetle Shell!

Tang Chen jumped up and ran all the way back to the camp at the bottom of the valley.

For more than a month, Tang Chen and the kitten fed on black beetles every day. A black beetle can provide about two pieces of meat the size of a fingernail, and one person and one cat initially have to catch at least a hundred or more per day, but as Tang Chen consciously increases the amount of food, the daily consumption of black beetles is more. The shells, legs, and other inedible torso parts of the black beetles, Tang Chen had intended to throw the remains of those black beetles into the fire to burn them, so as not to be an eyesore there, but those remains were extremely fire-resistant. The small fireballs could slowly burn the remains of the black beetles, but Tang Chen didn't have that much spare time, so he had to pile them up in a corner of the camp.

The black beetle's shell was extremely hard, and when Tang Chen first confronted it on the tree, the barbecue fork knocked on the black beetle's body, clanging like a golden stone, and its hardness could be seen. When processing the black beetle meat, Tang Chen found that the quality of the black beetle shell was not large. Lightweight and stiff, isn't it the best protective material?

Although each black beetle shell is not large, it is better to have more than enough.

If there are not enough insect shells, there is plenty of supply in the valley, and it is a big deal to let Little Tom do more killing. Anyway, the little guy is very good at doing these things, and they are already full of blood, and they need to stock up on food......

With the clothes as the inside, the black beetle shell is strung on it in order, which is an inner armor.

Wearing insect beetles inside and rattan clothes on the outside, this protection should be enough, right?
