"Goo~~~"

In the early morning, Chen Zheng was woken up by the strange sound of water, and hunger drove Chen Zheng to get up.

Outside, the light was abundant, and the snow was blindingly white.

Chen Zheng, who had just gotten up, narrowed his eyes uncomfortably.

If the naked eye is exposed to such an excessively sufficient light environment for a long time, it is easy to cause snow blindness for a long time, and it will be bad if the vision is blurred and you can't see things.

However, at present, there are so many things that have to be prioritized to make eye patches, and in front of one thing, even solving the food problem has to be further back, and that is water.

People can live for 7 days without eating, but if they don't drink water for 3 days, it will be life-threatening, of course, according to each person's differences, this data will fluctuate up and down, generally speaking, women will live longer than men, but generally speaking, this data still has a certain reference value.

Although there is snow and ice everywhere, it looks like good fresh water, but in fact, the temperature is too low, and it is okay to eat small amounts, but if you eat a large amount, it is likely to burn the mouth and esophagus, and if you are injured in these two places, you will not be able to eat even if there is food, but it will become a fatal factor.

In addition, the snow is not as white as it seems, and it is mixed with a lot of dust and even low-temperature resistant bacteria and viruses.

Surviving alone is a hurdle every step of the way, and if you are not careful, you will die in Huangquan.

After a few stretching movements, Chen Zheng picked up the previous bark shovel and went to the forest to dig up the snow with the bark.

Under the snow was a thick layer of dead branches, fallen leaves, and yellowed grass.

Chen Zheng picked up some dead branches that were not stained with snow, and cut some hay. After returning to the open field on the shore, lay the bottom with hay and erect dead branches, and a simple campfire stand is completed.

The campfire rack is there, and the remaining problem is the tinder.

Chen Zheng first picked a dead branch the thickness of an egg and split it, scraped the section flat with a dagger and put it aside.

I picked a straight root from the dead branches all over the ground, cut off the bark and branches, and cut out a dull finger-like tip at the top, and used it as a drill in a moment.

Putting down the drill bit, Chen Zheng dug a finger-sized pit on the freshly scraped dead branches, repaired it to about the same size as the drill bit, and then dug a "V" shaped hole next to the wooden pit.

When the drill bit rotates in the pit, the temperature will gradually increase due to friction, and finally even jump out with spark-bearing debris, which will fall from the "V" shaped gap to the underneath the velvet due to squeezing and rotating, and at this time, as long as you blow gently, the velvet will ignite.

When Chen Zheng tore the hay into extremely fine silk as velvet, the most basic conditions for drilling wood for fire had been achieved. However, let Chen Zheng, a city person, put his hands together and rub the wooden stick hard, thinking that this would make sparks...... It's better to pray and fill up the next lighter.

Lack of physical strength and intelligence supplement.

The reason why man became the spirit of all things was never by physical strength.

"So, ...... next"

Chen Zheng's gaze looked at the towering trees next to him.

With a dagger in his hand and a thick branch, Chen Zheng found a tree and began to "cut wood".

Holding the dagger horizontally on the trunk with his left hand, and then striking the back of the dagger with a branch, the blade gradually sank into the trunk of the tree with one blow after another.

Next, using this method, Chen Zheng first peeled off a large piece of bark about one meter square, and then continued to repeat the previous action, cutting a rectangle on the hard trunk, and finally knocking the dagger into it from the side, using the principle of levers to warp out the pieces of wood, and slowly digging from all sides to the center.

At first, the dug up pieces of wood were only two fingers thick and useless. However, as he dug deeper and deeper, the wood gradually became thicker and larger, until Chen Zheng dug out a lump of wood the size of a volleyball, and then stopped, taking it and the bark back to the campfire.

Spreading the bark on the snow, Chen Zheng sat down and began to carve the "volleyball".

Knock the dagger into it along the texture of the wood, and in the center of the "volleyball" size of wood, take out a piece of wood about two fingers thick, turn it in your hand to find the center of gravity, and then use the dagger to carefully make a small hole in the center of gravity.

Chen Zheng put aside the pieces of log, tore out a few strips of cloth from his clothes and kneaded them into ropes, brought the drill rod he had prepared before, split a groove at the tail, buried the center of the cloth rope in it, and then tied the two sides of the split tightly.

Then, Chen Zheng split a dead branch, took a piece of wood about 20 centimeters long and 5 centimeters wide, and made a larger hole in the center so that it could easily slide along the wooden pole as the handle of the whole device.

In this way, the wooden pole with two "tails", the wooden wheel with a hole in the center and the wooden handle are ready.

First of all, knock the wooden pole into the hole in the center of the wooden wheel and fix it, the distance from the wooden wheel to the drill bit is about one-third of the whole wooden pole, and try to turn it firmly enough. When you do this, the whole installation is like a wooden spinning top.

Next, Chen Zheng threaded two cloth ropes of equal length through the hole in the center of the wooden handle, threaded the wooden handle all the way to the wooden pole, carved grooves on both ends of the wooden handle, and tied the two cloth ropes to each end of the wooden handle.

In this way, the installation is ready.

This device was first invented by the Iroquois people of the Americas, and for the sake of respecting history, let's call it the Iroquois fire diamond.

Chen Zheng found a dead leaf to pad on the bark, took some hay torn and put the velvet on the leaves, put the grooved dead branch at the velvet and stepped on it, picked up the wooden handle of the Iroquois drill and turned it a few times, let the cloth rope wrap around the wooden pole, and then put the drill bit of the wooden pole on the groove.

After holding the fire drill steady, Chen Zheng began to press down on the wooden handle.

The cloth rope wrapped around the wooden pole is gradually tightened as the wooden handle is pressed down, and the wooden pole begins to rotate slowly under force. The kinetic energy of rotation not only generates heat by friction at the head of the drill, but also stores the kinetic energy of rotation on the wooden wheel.

As the wooden handle was pressed to the bottom, although the force on the rope disappeared, the kinetic energy stored by the wooden wheel continued to rotate, and as the wooden pole rotated, the cloth rope was wrapped around the wooden pole again.

When the kinetic energy of the wooden wheel was released, Chen Zheng pressed down on the wooden handle again, and the fire drill spun rapidly again in the opposite direction.

Although the device is simple, it cleverly uses the wooden wheel to store the force, so that the utilization rate of energy is increased several times, which not only reduces power consumption, but also improves efficiency.

Compared to the primitive method of drilling fire that may not be able to rub out the spark after a few hours of hard rubbing, it is only a few minutes before the hot chips in the velvet have begun to smoke.

Chen Zheng carefully blew the velvet, and a small flame suddenly appeared.
