Lin Shuhang carried the mushrooms to the top of the mountain and pulled out a huge moss-covered skull from the cave.
The skull was the size of a truck and weighed almost a ton.
It looked like it should be the head of a Tyrannosaurus Rex, which had been kept as a trophy by the female giant in the cave for many years. Today, Lin Shuhang decided to use it as an iron pot to cook food.
"I'm afraid I, Lin Shuhang, am the only one in the world who uses dinosaur skulls as iron pots, right?"
Lin Shuhang supported the huge skull with stones, found some dead old trees, squatted on the top of the mountain, and prepared his first delicious meal on the Titan Continent.
But when he got water from the stream and made a fire, he ran into trouble.
Before becoming a bloodline giant, Lin Shuhang had always lived in a civilized society and used lighters to make fire. Now that he has returned to the primitive world, making fire has become an unavoidable problem.
Fortunately, Lin Shuhang had read many programs and books about survival in the wild before his death, and he still knew some methods of making artificial fire.
The first thing that came to Lin Shuhang's mind was definitely drilling wood to make fire.
This is the oldest method of making fire for mankind. It was born in the ancient caveman period and has a history of almost 20,000 years.
Its principle is very simple, it uses the principle of frictional heat to ignite fire-making objects.
In the Stone Age, which relied on thunder and lightning and volcanic lava to make fire, drilling wood to make fire was undoubtedly a great revolution for mankind to get rid of natural forces. It can be said to be a crystallization of wisdom with epoch-making significance.
People who have never eaten pork may not have never seen pigs running. Lin Shuhang is quite confident in his abilities.
He found some dry moss on the cliff and used it as tinder to start the fire. He picked up a large tree as thick as a water tank, squatted on the ground and clumsily started a fire.
Although drilling wood to make fire seems simple, it is actually one of the most time-consuming and energy-consuming methods of making fire, and it places high demands on human skills.
As expected, Lin Shuhang failed. After drilling for a long time, his hands were sore and he could not get out the smoke.
Lin Shuhang was not angry about this. In order to eat delicious food on the Titan continent, he considered other ways to make fire.
In the long history of human civilization, the method of making fire that is comparable to making fire by drilling wood is the method of making fire with rocks.
This is the least technical method of making fire. It only requires two stones to collide with each other to create sparks and ignite the fire. Compared with the time-consuming and energy-consuming method of drilling wood to make fire, this method seems to be more suitable.
A clumsy person like Lin Shuhang.
The most indispensable thing on the Titan Continent was stones. Lin Shuhang grabbed two stones from the mountain with a big hand and effortlessly.
But he ignored the most important point, not just any kind of stone can create sparks.
After knocking for a long time, several rocks were broken into pieces, but no sparks were produced, which made Lin Shuhang completely lose his patience.
"Damn it, it's so hard to make a fire!" Lin Shuhang threw the stone in his hand angrily and lay on the ground sulking.
The sun gradually rose into the sky, and the dazzling sunlight made Lin Shuhang feel upset.
Suddenly, as if he thought of something, Lin Shuhang suddenly slapped his head, "Yes! I can use sunlight to make a fire?"
Lin Shuhang recalled the scene when he used a magnifying glass to burn ants when he was a child. The focused sunlight burned the ants to char almost instantly.
During that naughty childhood, he used a magnifying glass to burn big holes in the door and wooden bed at home.
Lin Shuhang couldn't help but be excited about his idea, and sat up from the ground like a carp.
But then Lin Shuhang ran into a problem. In this primitive and mysterious continent that looked like a prehistoric world, how could there be any magnifying glass?
Although he thought of using ice cubes to grind concave and convex mirrors, there is only one season like spring on Titan.
The idea of grinding concave and convex mirrors with ice was obviously not feasible. For a while, Lin Shuhang was upset by this.
"Forget it, forget it, I won't eat anymore!" Lin Shuhang held back his anger and went back to his cave in depression.
As the saying goes, there is no way to reach the mountain, but there is another village with dark willows and bright flowers.
Just when Lin Shuhang completely gave up the idea of making fire, he unexpectedly discovered an ancient crystal mine in the cave!
Spar is a rare mineral that usually exists in the form of crystal clusters and geodes.
The number of crystal minerals Lin Shuhang discovered was not very large. They were scattered and inlaid on the stone walls of the cave, covered with a thick layer of mud and moss over time.
When the mud and moss on it were peeled away, the exquisite crystal stones were immediately exposed. The dark cave looked like stars in the sky, bursting with dazzling colors.
This discovery made Lin Shuhang very excited. He immediately picked out a few crystal stones from the stone wall, held them in his hands and studied them carefully.
These crystals have different shapes. Although they are not very large, they are still enough for grinding convex mirrors.
Lin Shuhang immediately took the spar out of the cave and polished the spar on a huge stone wall.
Crystal is a natural mineral with very high hardness, its hardness is about 7 degrees on the Mohs scale.
Mohs hardness is a set of standards for identifying the hardness of minerals formulated by the German mineralogist Mohs. That is, those that can draw marks on paper are 1 degree, those with the same hardness as human fingernails are 2.5 degrees on the Mohs scale, and glass is 5.5 on the Mohs scale.
Steel is 6 degrees on the Mohs scale, and the hardest is diamond, which has the highest hardness of 10 degrees on the Mohs scale.
In other words, grinding crystal is at least equivalent to grinding the same volume of steel!
Without the help of modern tools, this is a lot of work.
And because crystal is very brittle, it is much more difficult than grinding steel.
But Lin Shuhang has plenty of time.
In this primitive and mysterious Titan continent, which is like a prehistoric world, time seems to be a superfluous thing to him, which can be used to kill loneliness.
In order to grind out a convex mirror for focusing sunlight, Lin Shuhang spent three days. Almost the entire mountain wall was worn away by him, and finally an oblate chip appeared in his hand.
I looked at it under the sun and found that the light transmittance of the chip was not very high and it could not be used to focus light and make fire. It must be further polished and polished.
Fortunately, the cave where the bloodline giant lives has gone through the baptism of time, and its surface has been severely weathered. There is a lot of fine gravel accumulated in the cave, which is perfect for polishing chips.
Lin Shuhang finished processing his own chip in the sand.
After Lin Shuhang successfully ground a crystal piece with high translucency in the gravel, on a whim, he pointed the crystal piece at the noon sun.
Lin Shuhang took the chip and took a photo of his giant pan-like hands. The sunlight focused by the chip almost instantly scorched his skin. Lin Shuhang hugged his palms and screamed in pain.
"You are so smart!"
Lin Shuhang excitedly shook off the flames in his hands and ran back to the huge bone pot.
The moment the blazing flame burned at the bottom of the pot, Lin Shuhang felt that his life was full of hope.
"One day I will turn this prehistoric continent into my paradise!"
Lin Shuhang said this as he looked at the vast virgin forest at the foot of the mountain.
