Chapter 8 Stone Blades and Flames

This black metal tube is not big, just two fingers thick and a palm long. However, this tube, which is estimated to not be able to hold a 250 ml bottle of Coke, can hold 0.25 cubic meters of compressed oxygen!

A person consumes about 550L of oxygen a day, which is about 0.5 cubic meters.

0.25 cubic meters of oxygen is enough to ensure a person's breathing for about 12 hours.

There is also an expansion position in this air chamber, where one more air bomb can be inserted. Two air bombs and 0.5 cubic meters of compressed air are enough to maintain a person's normal breathing for 24 hours.

The right leg is equipped with gas bombs, and the left leg is equipped with batteries.

It is understood that this protective suit uses a solar flow battery, which is a technological product that Fang Yu has never heard of.

Fang Yu checked the encyclopedia. The above records show that this kind of battery has very good charging and discharging characteristics, and the electric energy capacity is extremely considerable. It has extremely high utilization and storage effects for green energy such as wind energy and solar energy.

It is a commonly used energy storage battery in society today.

The white paint film on the surface of the PT normal protective clothing is also a high-tech. This paint film can directly absorb sunlight and convert it into solar energy through the micro wires underneath, charging this set of solar flow batteries all the time.

As long as there is sunlight, with this protective suit, you can basically achieve electrical energy recycling and continue to use it.

And now, it seems that this sunset will never set.

This is a rare piece of good news for him.

After taking out the air bomb, Fang Yu followed the previously searched instructions and pulled out the connecting port of the air bomb, then removed the link nozzle, pushed down the high-density piston in the air nozzle, then put the link nozzle back and pulled it.

Automatic inflation device on the outlet link.

Finally, connect the power supply and the air bomb will start to automatically inhale and oxygenate.

There is a filter device on the link mouth that can filter the gas, absorb only oxygen, and discharge other gases on the other side.

Until the air pressure in the bottle reaches a certain level, push back the high-density piston and the inflation is completed.

The self-inflating air bomb is like a deflating balloon when held in the hand. Air is continuously sucked in and expelled.

This process will last about half an hour. In order to supply power to it, Fang Yu can only move it with a gas bottle.

Moving to the lifeboat, Fang Yu placed the gas bottle on the air cushion and began to knock rocks.

The edge of the long stone had been knocked out by Fang Yu before. This time Fang Yu carefully took the stone blade and sharpened the edge on the rock wall to make it even sharper.

The stone powder fell away, and the stone blade became sharper as Fang Yu carefully added seawater to grind it.

Fang Yu was fully immersed in it, and Fang Yu didn't feel the passage of time at all.

The sound of the filling of the cylinder sounded like a cheering sound to his ears, making him even more focused.

It wasn't until he sharpened the stone blade and stood up with his waist bent that he noticed that the gas bomb had been charged at some point!

Fang Yu excitedly picked up the air bomb, pressed the inflatable device back, then connected the air nozzle, put it back into the air tank on her leg, closed the tube and zipped it up.

Click on the terminal, and sure enough, this time the oxygen content displayed on the display directly reaches 70%!

yeah!

Fang Yu waved her arms happily.

Checked the time again.

16:20.

It's already afternoon.

Looking at the sun still hanging on the sea.

This sunset is a bit annoying.

At this time, Fang Yu's stomach began to growl, and Fang Yu realized that she had been working continuously for more than seven hours without drinking any water or eating a morsel of food.

When he realized this, the physiological reaction that had been suppressed due to his high concentration suddenly surged up.

My throat was so dry that it was almost smoking, and my stomach was growling.

After taking off the helmet, due to the loss of the airtight environment, the "internal air conditioner" with constant temperature and humidity stopped starting, causing Fang Yu to sweat profusely.

Fortunately, at this time, Fang Yu's perseverance skill was still activated.

Perhaps, it was precisely because of this skill that Fang Yu was able to suppress these physiological reactions.

However, after confirming that the outside world did not seem to have much impact on his body, at least, it would not be fatal, Fang Yu simply took off all his protective clothing!

Fang Yu, who was inside the protective suit, was wearing a tight suit that looked a bit like a diving suit.

Fang Yu was barefoot, exposing her body directly to the air.

Although Fang Yu knew that she might get radiation sickness.

But it's obviously impossible for him to wear protective clothing all the time.

He had had enough of the inconvenience of sharpening a stone blade while wearing protective clothing!

After taking off the protective clothing, Fang Yu instantly felt relaxed and no longer as hot as before.

Fang Yu picked up the coconut that she had picked before.

The newly sharpened stone blade came in handy immediately.

Fang Yu used the stone blade as a nail, and gently knocked the stone blade into the inside of the coconut with a stone, then pulled it out, and used the tip of the knife to gently grind the incision to make a slit.

Then, Fang Yu picked up the coconut and started pouring it towards her mouth.

Transparent coconut milk flowed out from the slit and flowed into Fang Yu's mouth with some fine sand.

Fang Yu swallowed the coconut juice in big gulps.

There is not much coconut juice in one coconut, so Fang Yu drank up all the coconut quickly.

The water and sugar content of this coconut successfully brought Fang Yu back to life.

The Iron Stomach skill played its due role at this time.

If an ordinary person drinks coconut water like this when they are extremely thirsty and hungry, it won't take long before their stomach and intestines can't stand the stimulation, and they will either have abdominal pain or diarrhea.

But Fang Yu's Iron Stomach ignored this side effect.

The powerful digestive function digested the energy of coconut water without any waste and supplied it to Fang Yu's whole body, making Fang Yu feel a little happy.

After drinking the coconut juice, Fang Yu placed the coconut on the rock wall again, inserted the stone blade into the incision, and then slowly tapped the stone blade to split the coconut bit by bit.

This stone blade passed Fang Yu's functional test smoothly.

After splitting the coconut, there were no cracks on the stone blade.

This stone blade has met Fang Yu's requirements.

After splitting the coconut, Fang Yu continued to scrape the pulp inside the coconut with a stone blade and put it into his mouth to taste.

This coconut may have been dropped for a long time.

The coconut milk is very sweet, but the pulp tastes like it has been fermented.

However, even if the taste is a bit strange, the pulp has not deteriorated and can still be eaten normally.

After eating a coconut, Fang Yu's physical strength recovered a little.

Now that the protective clothing has been taken off.

It was also confirmed that there was no radiation or poisonous gas in the outside world that could kill people immediately.

Then, it's time for him to light a fire.

Whether it's distilling fresh water or cooking food.

Lighting a bonfire is the most important thing.

Fang Yu came to the fire pit and picked up some dead leaves and branches, as well as some wet raw wood.

Reluctantly use some dead leaves to rub it into tinder, rub it quickly, and use the warmth of your hands to make it dry more.

Fang Yu kept rubbing until Fang Yu felt that her hands were about to catch fire. Fang Yu had already rubbed these dead leaves into strips, with a fine texture and a lot less moisture.

I made a few more strips, then rolled them into a ball, surrounded them with twigs and other dead leaves, and placed them on the ground.

Start using a flint to light the ball of velvet.

The flints cut into each other, sparks flew out, and sparks kept hitting the tinder ball.

After a while, a small fire point fell on the tinder ball, and the tinder began to smoke, and a small spark appeared.

Fang Yu quickly put the flint aside, carefully lifted the tinder ball, and blew gently.

The smoke went from curling at the beginning to thick at the end, and finally, the small spark slowly turned into a small flame, and then ignited the entire tinder mass.

This is the first flame of the new world!

------Digression-----

A copy of the experience, there is no such story in the real world ~ Everyone is considerate, so Fang Yu will not know the story of the wandering earth
