Compared with fans, the biggest advantage is that they can concentrate the wind.

If Wang Wei is given the right place and enough time, he will be able to make a blast furnace and a hydraulically driven windmill.

A blower like this that is powered by humans is really tiring after rubbing it for a long time.

The two hands were raised in the air and rubbed them all the time. Even if Wang Wei and Wang Siwu were taking turns to rub them, their hands were so sore.

Thinking that he might have to rub the branches like this for six or seven hours, Wang Wei almost gave up on this firing.

I don’t know who said that laziness is the driving force for the development of human science and technology, and this sentence is not false at all.

When Wang Wei was so sore that he couldn't lift his hands, he suddenly remembered the scene of playing with bottle caps when he was a child.

The iron beer bottle cap is flattened with a hammer, two eyes are stamped in the middle, and threaded with a rope to tie it.

Then, by rotating, the rope will be entangled together, and then pull it hard. The rope will return to force, and the bottle cap will be rotated, and the rope will be entangled in the opposite direction.

Pulling the rope back and forth in this way, the bottle cap will rotate back and forth, bringing a lot of joy to Wang Wei's childhood.

Thinking of this, Wang Wei, whose hands were sore, had an idea, took a piece of straw rope over, and fixed the middle part of the straw rope on the top of the wooden stick.

Then rotate the stick several times to wrap the straw rope around the stick.

Then he pulled the straw rope with both hands, and the wooden stick really started to rotate.

And when the rope is pulled straight, the wooden stick continues to rotate according to inertia, wrapping the rope around the stick in the opposite direction.

After the rotation of the wooden stick stopped, Wang Wei pulled the straw rope again, and the wooden stick turned back.

After pulling this way, the wooden stick always rotates back and forth, which also drives the wind leaves to suffocate the wind.

"Shock points from Wang Siwu +99"

Wang Siwu, who was rubbing his arms aside, looked at the solution Wang Wei thought of, and was shocked, his eyes full of admiration.

Is this possible?

If you rub a wooden stick with your hands, let alone the blood blisters that are ground from your hands.

Over time, the feeling of soreness in your arms is unbearable.

Now, using Wang Wei's method makes the work of rubbing wooden sticks countless times easier.

Just sit by the stove and pull the rope back and forth with both hands.

After taking the straw rope from Wang Wei's hand, Wang Siwu tried to pull the straw rope for a while, and a happy and satisfied expression appeared on his face.

Compared to rubbing wooden sticks with your hands just now, this method is really too simple and easy!

Wang Siwu felt that if he did this kind of work, he would not have any problems even if he persisted for a whole day.

Wang Wei stood up and handed over the care of the stove completely to Wang Siwu.

He felt that it would be no problem to award himself a Nobel Prize for invention based on his invention.

In fact, what Wang Wei didn't know was that his method was just the rest of it.

In many areas, primitive people drilled wood and used straw ropes to turn the wood.

After all, if you rub the wood directly with your palms, it is difficult for ordinary people to increase the speed to the point where you can ignite the flame.

Only those who are amazingly physically strong and can call a human-soft stick machine can rub wooden sticks with bare hands to drill wood to make fire.

Time passed slowly as Wang Wei waited.

During dinner, Wang Wei and Wang Siwu replaced them and took turns to eat meat, but the fire did not stop for a moment.

Wang Wei also endured the high temperature in the middle and asked his tribe members to hold him up and take a high look at the situation in the furnace.

The mud bowl and clay pot in the stove were burned red by the fire, and it looked like boiling magma. I don’t know if it has been burned.

However, when Wang Wei was on Earth, he heard others say that it would take at least four or five hours to burn ceramics, and it would normally take seven or eight hours to burn them.

Some ceramics even require special processes, and it is normal to fire for dozens of hours.

So Wang Wei resisted the urge to take out the mud bowl and clay pot in the stove, and waited until after dinner.

If the time is not estimated incorrectly, the pottery pot should have been burned for seven hours.

After extinguishing the fire, when the temperature dropped slightly, Wang Wei couldn't wait to use wood to pick up a bowl from the stove.

The original mud bowl was burned red and emitted a red light in the darkness.

Fan the mud bowl with your hands, waiting anxiously for the mud bowl to cool down.

Although there was snow not far away, putting the mud bowl in would not take long to cool down, this sample bowl that was made into shape and was not broken for the first time was too important for Wang Wei. He was really worried that the sudden expansion and contraction of the heat would crack the bowl, so he could only wait patiently.

As the mud bowl cooled down, its color gradually changed from red to black.

When these bowls and jars were fired, the glaze on Wang Wei was actually some mud made of the same material as the mud bowl.

So it has little impact on color.

When firing pottery, the more iron the soil contains, the darker the color of the finished pottery jar.

The pottery bowl burned this time turned completely black after cooling.

Enduring the hot heat, I couldn't wait to pick up the pottery bowl.

I don’t know if it’s because of the insufficient temperature or the material, the surface of the pottery bowl after firing is very rough.

Even at the bottom of the bowl, there are some fine particles.

Although it is not beautiful, there are no cracks on the surface of the bowl.

Wang Siwu participated in the firing of the pottery bowl throughout the process. Now that he saw the finished product, he immediately came up.

"Wang Wei, what is this? What's the use?" Wang Siwu asked at Tao Wan.

"This is a treasure!" Wang Wei smiled mysteriously.

Then, in a confused look, Wang Siwu scooped a handful of water from the pond and poured it into a bowl.

After waiting quietly for a few minutes, the outer wall of the pottery bowl was as dry as before, and the water in the bowl was not leached.

Seeing this, Wang Wei waved his fist excitedly.

It's done!

To be honest, Wang Wei did not expect that he successfully burned the pottery bowl just for the second attempt.

You should know that firing pottery is very troublesome and requires many processes.

If any process is wrong, all previous efforts may be wasted.

Wang Wei was able to succeed twice, which was considered a great fortune.

Although the pottery bowls made this time look ugly, this does not affect the overall situation.

Since you know the approximate time of firing, adjust the time next time and then slowly explore it, Wang Wei is confident that he will be able to burn the exquisite pottery on the earth in no time.

Soon, the rest of the pottery in the stove was taken out.

Seven pottery, five, two of them cracked for some unknown reason.

In the end, Wang Wei harvested two pots and three pottery bowls.

Unfortunately, both the clay pots and the clay bowls are stained with some ugly small particles at the bottom, which makes it uncomfortable to touch and feel uncomfortable to look at.

The excitement of successfully harvesting pottery made Wang Wei ignore these things and turn to find meat.

After being in this world for so long, Wang Wei's throat was smoking after barbecue every day.

Now he really wants to have a sip of the broth.

Even if there is no salt, even if there is no oil or water, Wang Wei wants to drink a sip of hot broth in this cold weather.
