After making a bet, the two of them watched Wang Wei's movements more attentively.

However, no matter how they looked at it, they could not find any signs that Wang Wei could use ice to raise a fire.

Soon, the ice plate was ground into the shape of a convex lens.

However, because the polishing place is on the stone, the ice-made convex lens is full of scratches and white wear marks.

The originally crystal clear ice cubes have lost their transparency.

No matter how standard the shape of such a convex lens is, it cannot be used.

After confirming that the shape was fine, Wang Wei took a deep breath, lifted up the clothes on his upper body, stuffed the ice directly into the clothes, and rubbed it on his stomach.

Tongshu and pine cones were stunned when they saw Wang Wei's movements.

In such cold weather, people wanted to wrap themselves in animal skins, but Wang Wei directly stuffed a big ice lump on his belly.

Not to mention trying, just looking at the tung trees and pine cones, I couldn't help but shivering.

What does it feel like to stick a large ice cube directly onto the belly?

One or two can be seen from Wang Wei's hideous face.

In the middle of winter, even if you are a friend who is very close, you will be able to turn your face off by pressing your cold hands on your belly, and the ice cubes are several times lower than the temperature on your hands.

This feeling is indescribable, only whoever tries to know.

Feeling the colicing internal organs, Wang Wei rolled his eyes in pain.

It’s not that Wang Wei has a tendency to be masochistic, but because this was a decision he had no choice but to make.

The wear marks on the surface of the ice cube cannot penetrate the ice convex lens at all. Only by melting the broken ice slag into transparent pure water and making the surface of the convex lens smooth and light-transmissive can it be used as a fire.

Wang Wei spent a lot of time polishing the convex lens. The pine tree's temperament is obviously not the kind of very patient.

During the polishing process just now, my hands were completely frozen. It would take a lot of time to melt the ice slag on the surface of the convex lens. Whether it was a pine tree or the sun hanging obliquely in the air that was about to set, it would not give him so much time.

Therefore, for Wang Wei, the only way is to use the warmest abdomen to polish the ice-made convex lens for the last time.

Tongshu and Pinecone were both stunned.

They really couldn't figure out what kind of nerves Wang Wei was experiencing, and actually stuffed the ice into his stomach.

"Shock points from the tung tree +2+4+1+4+2..."

"Shock from Pinecones..."

In just two minutes, the tung trees and pine cones provided Wang Wei with more than 100 shock points.

Two minutes later, when Wang Wei took out the ice from his arms, the surface was covered with ice slag, and the rough ice cubes like stone became crystal clear and smooth.

From this ice-made convex lens, Wang Wei could clearly see the surprised expressions of the tung trees and pine cones.

The light transmittance is perfect and the smoothness can be scored 70%. Although there are certain flaws, this convex lens is more than enough to use for fire production.

"Two, don't forget the bet we made just now. I'll make a fire for you to show you!" Although my stomach hurts, Wang Wei still said with a smile.

After saying that, he took a small handful of flammable dead leaves and greased animal fur on a clearing without snow.

Then, the angle was found and the sunlight was concentrated on this small troubling of fire-induced objects using a convex lens.

The sunlight in winter is far worse than that in summer, and now the most lit period of the day has passed.

However, Wang Wei had already taken all these situations into consideration. The convex lens he made was as big as an ordinary dish serving plate, the size was several times the size of a magnifying glass that cost a dollar on the street stall. The sunlight that could be gathered was also several times the size of an ordinary magnifying glass.

If the quality is not enough, I will make up the quantity.

Sure enough, within a dozen seconds, the small pile of ignition materials piled on the ground floated white smoke.

"Shock points from the Tung Tree +99"

"Shock Points from Pinecones +99"

The two of them turned their heads in disbelief and stared at the light spot as the size of a little finger condensed by the convex lens.

"Hehe, don't block the sun, how about it? I won. Can ice cubes start to catch fire?" Wang Wei pushed the tung tree blocking the light aside and smiled.

While speaking, the ignition material of white smoke rose up and turned into a cluster of small flames.

"Shock points from the Tung Tree +99"

“From…”

When the two saw the open flame, they added a lot of shock points to Wang Wei.

Wang Wei added some tiny dead branches to lure the small flame into a small fire.

From the fire, Wang Wei felt the long-lost warmth, and even his coliced ​​belly felt much more comfortable.

Tongshu and pine cones looked at Wang Wei with shock. Wang Wei, who was just a spare food in their eyes, had a sense of unfathomable mystery at this moment.

"I'm starving to death. Is the fire arising? If the fire has not been generated yet, there is no need to be born. Take that guy in and eat it!" The voice of the pine tree came from the cave.

His words instantly made Wang Wei feel a little out of the way through systematic translation.

The primitive man did not have the concept of "Laozi". Needless to say, this sentence must be a play added by the system.

Hearing the sound of the pine trees, the tung trees quickly responded: "The fire is born, so everyone can come out to work!"

Shortly after the speech was finished, the pine trees quickly emerged from the cave.

"Huh? It's really aroused the fire. Today I'm so cold that I can't even get the fire. How did you get it?" Songshu asked suspiciously.

Before Wang Wei could speak, the pine cones rushed to answer: "Pine, pine tree, he, he put the ice cubes in his stomach, take it out, and after it comes out, it will shine, and then use the ice cubes to shine to make the fire grow!"

After hearing the words of the pine cone, the pine tree kicked him over and said angrily: "Go your mother's ice cubes shine, how can the ice cubes shine? You dare to lie to me, believe it or not, I will bake you and eat it!"

Songguo climbed up from the snow with a grievance. He couldn't understand why he was telling the truth and was kicked by the pine tree.

When Tongshu saw the pine cone being beaten, he quickly swallowed the words in his mouth. While Wang Wei fiddled the fire to make it burn more vigorously, he smiled and said to the pine tree: "King, I am lucky to have the fire. You are so hard today. Come and roast the fire quickly to warm up your body!"

Wang Wei changed the topic and made the pine tree forget to ask him how the fire came about.

The pine tree next to the fire shouted into the cave: "You group of lazy pigs have fire outside, so why are you still huddled in the cave? Come out and roast the serrated pigs and eat them! I'm about to starve to death!"

After hearing the words of the pine trees, the talents in the cave came out one after another.

Compared with the inside of the cave, the temperature outside is much lower. As soon as it comes out, many people can't help but shiver.

This tribe of Pine Tree seems to be very difficult to live.

Except for the five people from Chun Shu who went out to find Chaihuo today, the remaining people, even a few men who looked stronger, had only a small amount of animal skin wrapped around the vital parts.

Those women were even more miserable, with yellow weeds or thick bark wrapped around their bodies, and their arms and thighs were almost exposed in the air.

Fortunately, the temperature in the cave is relatively high. If it weren't for this cave, these people would probably not be able to survive for a night in such temperatures.

Judging from the system prompts during time travel, Wang Wei traveled through a parallel world of primitive society.

When he was on Earth, Wang Wei also read a lot of historical books. In the early days of primitive society, humans still had many long hairs on their bodies to keep warm.

Moreover, at that time, humans were relatively short and lived in some tropical or subtropical areas.

At least, the place where they live, even in winter, would not encounter such heavy snow and cold weather.

Although it is a parallel world, the evolution of species should be quite different.

But now, the situation in the book is a bit different from what Wang Wei sees now.

The body hair on these primitive people is not thick, at least it is acceptable to put their body hair to modern times.

Moreover, she is not short. In the past, the height of adult men is almost 1.65 meters above 1.65 meters, while the height of female primitive people is also close to 1.6 meters above 1.6 meters.

Of course, what makes Wang Wei most pleased is that these primitive looks are all Asians with yellow skin and dark hair.

If Wang Wei was embarrassed if he came over and found that the people around him were all blonde hair and blue eyes or black as black as coal.

After walking out of the cave, the women in the tribe each carried a pile of dead trees and put them in the fire, then shrank to the edge of the fire to keep warm.

When he came to the primitive world, Wang Wei was actually very curious about how they handled the food.

Next to the cave is a stream. Although the surface is frozen, there is still flowing stream water below. It should be very convenient to clean animal internal organs.

But this serrated pig looks very thick when peeled and has no sharp knives. How should they break it open?

It’s impossible to use stones to slowly grind it, right? That’s what year it takes to grind it.

Just as Wang Wei was paying attention to how they processed the ingredients, the fire gradually grew.

The emitted temperature dispelled the cold around it, and the warm feeling made people feel comfortable and couldn't help but moan.

At this moment, two men in the tribe raised the serrated pig next to them, and then exerted force together, throwing the serrated pig directly into the fire.

The fire waves that were smashed scared Wang Wei to take a few steps back, but when he looked around, the rest of the people were used to it.

"This, won't we peel it and then bake it?" Wang Wei asked after touching the tung tree.

"Why should I peel it? The serrated pig's skin has no hair and cannot be wrapped around it to drive away the cold. Moreover, its skin is still edible. Wouldn't it be easy to burn if peeled off the meat!" If it were at the beginning, the tung tree would definitely not pay attention to Wang Wei, but Wang Wei had just successfully used ice to make a fire, and the tung tree was still shocked. He answered Wang Wei's question for the first time.

After hearing Tong Shu's words, Wang Wei's expression on his face was very vivid.

A group of mentally retarded people sold. Although the skin of the serrated pigs is very rough and cannot be used as clothes to drive away the cold, it is much better to make this tough animal skin with a little bit of nitrogen, sew it with fish bone needles, and seal it with pine oil to make simple boots than to run barefoot in the snow.

And this is just the simplest way to use serrated pig skin that Wang Wei thought of.

If he is given time, he can play with serrated pig skins, and everything is more useful than just putting them in a fire and eating them.

Although it was a pity that this pig skin, which felt even tougher than cowhide, Wang Wei didn't say much.

"By the way, I won't take out the internal organs and intestines of this serrated pig. Will I eat it like this later?" Wang Wei asked.

"Are you stupid? The serrated pig's belly has several layers of fat than ordinary animals. It is very troublesome to break it. Once it is burned, it will explode on its own, which will save a lot of trouble!" Tongshu said naturally.

After hearing this, Wang Wei stopped talking and quietly waited for the serrated pig to be burned.

A few minutes later, the smell of burning animals and the sizzling sound of oil burning came from the fire.
