I am a Primitive Man

Chapter 31: The great impact of simple truth

   The night was quiet, and the small flame at the entrance of the cave swayed weakly for a long time, and it seemed that it had to fall asleep like everyone in the cave.

   The old primitive man kept vigil by the fire, putting a little firewood into it from time to time.

   Keeping the flames from extinguishing is a very important task.

The appearance and use of    fire is a great leap in the history of human evolution!

   The tribe has also mastered the method of drilling wood to make fire, but this wood drilling is too troublesome. It is not as convenient as it is now, and it is convenient to send people to guard day and night.

   Anyway, these two old primitives are getting older, and the rest of the work is basically impossible.

   is covered with leather, and under the leather is a thick layer of withered grass. Han Cheng sleeps in a more comfortable place than ordinary people. If he had fallen asleep at this time before, but tonight, he had no intention of sleeping.

   There are generally only two reasons for insomnia at night, one is sleeping more during the day, and the other is worrying.

   In later generations, the first reason can basically be eliminated.

   As Han Cheng from later generations, the first reason can also be ruled out, because he didn't even close his eyes all day.

   The reason why he stays up at night is because he is full of pottery.

   He kept recalling every step of the pottery made by the old grandma in his memory, and then compared the procedures he performed this time, trying to find out the reason for the large gap between the two.

   He has been thinking about this matter from day to night and then into the night, but still doesn't have much clue.

   Although three suspicious places were found, Han Cheng always felt that these were not the main reasons for the massive damage to the pottery.

   Han Cheng sat up from the'bed', put on a leather coat, put on animal skin socks, and walked out of the cave. He has a habit brought from later generations, that is, if he can't sleep at night, he likes to wake up.

  The old primitive man who watched the night has long been used to someone going out to solve physical problems at night.

   Every time someone got up, he would turn his head and take a look. If he was an adult, he would sit next to the fire without standing up. If he was a child, he would need to get up and help the child open the heavy stone door.

   This is also one of his duties.

   The old primitive man turned his head habitually when he heard the footsteps. After recognizing that the person who came was the son of God, he quickly got up.

   Without waiting for Han Cheng to speak out, he already skillfully opened the stone door.

   The silence outside, only the bright stars embedded in the dark blue sky, looks exceptionally clear and beautiful, far from the later generations that pass through several layers of haze and pass through the neon night sky that is everywhere.

   In the night, from time to time there will be a few distant roars of beasts that seem to blend in with the night. This is the chanting of the ruling big brothers in the night.

The air was cold in the spring in the morning, and at night, even though it hadn’t reached the level of freezing, Han Cheng, who had just emerged from the cave, couldn’t help but shiver a few times, so much so that he was even shining. The water column has become a bit skewed.

   Han Cheng was trying hard. He wanted to quickly drain the water in his body and quickly return to the warm cave.

"Snapped!"

  Han Cheng did not go back, nor did he fall into the pit because of too much force. Instead, he raised his hand and slapped his head heavily.

   He was not crazy, but suddenly realized something, it was this thing that bothered him all day plus midnight!

   mother, such a simple truth was ignored by myself!

   suddenly outgoing Han Cheng can't wait to slap his head again.

   The reason why pottery will break in large numbers is simple, it is because of heat expansion and contraction!

   I warmed up and came out of the cave and was suddenly in contact with the cold air. He couldn't help shivering. The temperature difference was about ten degrees at most.

   When the pottery first came out of the kiln, it went from extremely hot to extremely cold, and the temperature difference in between was more than 100%!

   It would be strange if it didn't split under such a strong stimulus!

   After figuring out the relationship, Han Cheng relaxed in his heart and reached out to touch the frozen little finches, and hurriedly ran into the cave.

   The worries are gone, he lay on the bed and covered it with thick fur and soon fell into his dream...

   The small river is very lively, because I have witnessed the appearance of a miracle and experienced the usefulness of clay-fired pottery. People in the tribe now have a great passion for pottery.

  Especially after hearing that the son of God is preparing to burn pottery again today, everyone is even more positive.

   After eating early in the morning, they all came to the riverside.

   With the experience of the last time, this time I do it again, and everything goes smoothly.

   But compared to the last time, the pottery to be burned this time can be a lot more.

   Surrounded by the solid mud pit that was burnt last time, Han Cheng asked people to dig a lot around. After the excavation, the pit was almost four square meters.

   Then it is to spread hay, put mud embryos, fill hay, paste mud, light, and seal the hole.

   The only thing left is waiting.

The big brothers went hunting. Han Cheng took a group of little primitive people here while making mud embryos while guarding this simple mud kiln. He observed the temperature and small holes on the mud seal to see if the fire inside was extinguished. .

  Because there are already enough mud embryos in the bowl, if they are all fired successfully, one manpower is not a problem.

   Therefore, Han Cheng asked people to reduce the number of bowls and make more clay pots and large cylinders that are lacking.

   Pottery pots must be made.

   There are already a lot of mud embryos, so I don’t have to hurry as before~www.wuxiahere.com~ After noon, Han Cheng led the people to clean up by the river and returned to the cave.

   Because I have been busy with pottery these days, I have put aside the teaching of Mandarin and Chinese characters. Now the pottery is basically on the right track. Naturally, Han Cheng will continue the course that has been interrupted for a few days.

   What is being taught today is very simple, that is, the newly emerged "pottery" includes its pronunciation and writing, as well as the "pottery bowl", "terracotta pot" and "crock" derived from "tao".

Since everyone is very interested in the new "tao", even if the word "tao" is more complicated and difficult to write, everyone learns it quickly, especially the little pottery master Heiwa, who couldn't remember it before. The word "Tao" can silently write the word "Tao" very quickly...

   Around the flaming fire, there are three more rocks placed almost in a triangle shape. On the rocks are the clay pots that were just made, and there is water in the pots.

   Under the continuous lick of the flame, the water in the clay pot has begun to emit white gas.

   This made the old primitive man who was worried that the fire would crack the pottery, and then the water extinguished the fire with a sigh of relief.

   He was the same as the others in the cave. He didn't know what the **** child was doing in such a strange behavior, but now they have some habits. After all, the **** child made too many actions that they could not understand.

   Han Cheng didn't want to do anything, he just wanted to burn his mouth and drink hot water.

   has been here for a few months, except for the hot urine, he has never touched the rest of the hot water, and it is really sad to say it.

The water in the clay pot does not open when it is dry. This makes Han Cheng a little depressed. It seems that he has to make the lid immediately. This will not only prevent dust from falling into the water, but also play a role in heat preservation. .
