"Gu~~~"

In the early morning, strange sounds of water woke Chen Zheng up, and hunger drove Chen Zheng to get up.

There is plenty of light outside, and the snow is dazzlingly white.

Chen Zheng, who had just woken up, narrowed his eyes unadapted.

If the naked eye is exposed to such an environment with too sufficient light for a long time, it is likely to lead to snow blindness over time. At that time, the visual blurredness will make you unable to see things, which will be bad.

However, there are many things at present. The priority of making eye masks must be placed at a very back. In the face of one thing, even solving food problems must be placed at a further back, that is water.

People can live for 7 days without eating, but not drinking water for 3 days will endanger their lives. Of course, depending on each person, this data will fluctuate up and down. Generally speaking, women will live longer than men, but generally speaking, this data still has certain reference value.

Although snow and ice are everywhere, which seem to be the best fresh water, in fact, their temperature is too low and it is OK to eat in small amounts. If you eat in large amounts, it is very likely to burn the mouth and esophagus. If you get injured in these two locations, you can't eat even if you have food, which will become a fatal factor.

In addition, the snow is not as white as it looks, with a lot of dust and even low-temperature resistant bacteria and viruses. If you are alien, you will almost be sentenced to death if you get infected.

Surviving alone is a step-by-step obstacle, and you will die if you are not careful.

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

Under the snow is a thick layer of dead branches, fallen leaves and withered grass.

Chen Zheng picked up some dead branches without snow, and cut some hay. After returning to the open space on the shore, he paved the bottom with hay, set up the dead branches, and a simple bonfire rack was completed.

With the bonfire rack available, the remaining problem is the fire.

Chen Zheng first picked a dead branch as thick as an egg and split it, and used a dagger to scrape the section flat aside.

Pick a relatively straight one from the dead branches all over the ground, peel off the bark and fork, and cut out a finger-like blunt tip at the top, and use it as a drill for a while.

Putting down the drill bit, Chen Zheng dug a finger-sized pit on the dead branches that had just been scraped flat, which was about the same size as the drill bit, and then dig a "V"-shaped gap next to the wooden pit.

When the drill bit rotates in the wooden pit, the friction temperature will gradually increase, and finally even break out of the debris with Mars. These debris will fall from the "V"-shaped gap into the turtle below due to squeezing and rotation. At this time, just blow the air gently, the turtle will ignite.

When Chen Zheng tore the hay into extremely thin silk as turtle, the most basic conditions for drilling wood to make fire have been achieved. However, Chen Zheng, a city man, put his hands together and rubbed the wooden sticks hard, thinking that this would make sparks... It would be better to pray and fill in the lighter.

Inadequate physical strength and intellectual replenishment.

The reason why people become the spirit of all things is never based on physical strength.

"So, next..."

Chen Zheng looked at the towering trees beside him.

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

Holding the dagger with his left hand, he placed it horizontally on the trunk, and then tapping the back of the dagger with a forceful force. The blade gradually fell into the trunk with the repeated knocks.

Next, Chen Zheng first peeled off a large piece of bark about one meter square, then continued to repeat the previous movement, cut out a rectangle on the hard trunk, and finally knocked the dagger in from the side, used the lever principle to lift the pieces of wood out, and then slowly dig from all sides to the center.

At first, the wood pieces dug out were just small pieces of two fingers thick, which was useless at all. However, as the dig became deeper and deeper, the wood dug out gradually became thicker and bigger. It was not until Chen Zheng dug out a lump of wood the size of a volleyball and stopped and took it and the bark back to the bonfire.

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

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

Chen Zheng put the log aside, tore out a few strips of cloth from his clothes and rolled them into a rope, took the drilling rod that had been prepared before, split a groove at the tail, buried the center of the cloth rope, and tied the split sides tightly.

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

In this way, the wooden poles with two "tails", the wooden wheel with holes in the center and the wooden handle are all ready.

First, knock the wooden pole into the hole in the center of the wooden wheel and fix it. The distance between the wooden wheel and the drill bit is about one-third of the entire wooden pole. Try to turn it firmly enough. When doing this, the entire device is like a wooden gyro.

Next, Chen Zheng penetrated two equal-length cloth ropes into 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 the two ends of the wooden handle one by one.

In this way, the device is ready.

This device was first invented by the Iroquois in the Americas. In order to respect history, it is called the Iroquois Fire Diamond.

Chen Zheng found a dead leaf to put it on the bark, took some turtle velvet made of hay and placed it on the leaves, aimed the dead branches with grooves at the turtle velvet, put them down, picked up the wooden handle of the Iroquois fire drill, and rotated it a few times, wrapped the cloth rope around the wooden pole, and then pointed the drill bit of the wooden pole at the groove and placed it on.

After stabilizing the fire drill, Chen Zheng began to press down 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 the force. The rotating kinetic energy not only frictions and generates heat from the drill head, but also stores the rotating kinetic energy on the wooden wheel.

As the wooden handle was overwhelmed at the bottom, although the force on the cloth rope disappeared, the kinetic energy stored by the wooden wheel continued to rotate. 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 completely, Chen Zheng pressed down the wooden handle again, and the fire drill quickly rotated again in the opposite direction.

Although the device is simple, it cleverly uses wooden wheels to store force, which increases the utilization rate of energy several times, not only reducing power consumption, but also improving efficiency.

Compared to the original fire drilling method that can not be able to rub Mars hard for a few hours, it is just a matter of a few minutes that the heat chips in the turtle began to smoke.

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