There was no word all night, and when the sun had just risen, Big Tooth set off for the valley with more than 10 hunters and more than 50 captives according to Lin Yuan's request, preparing to log wood.

Wood is a must, at least until the invention of bronze metal forging technology to mine stone, wood will be the main material for buildings in cities.

Lin Yuan stood alone on the slope of the Huadu hills, looking out at the direction of the rising sun, and a warm breeze blew by, blowing his dark thick hair.

Behind him, the tribe's camp was in full swing, Ye and a large group of slaves were already preparing to set off for the swamp to farm, Lin Yuan had taught them how to dig holes in the ground with stone axe blades last night.

Because there is no metal, so the pear cultivation can not be talked about, the current situation, can only take this primitive way, fortunately, the number of seeds is not much, this planting method, primarily, there is not much problem.

"King Yan! Come and see!! ”

The shouts of several primitive people pulled Lin Yuan back from his contemplation.

He walked over, and it turned out to be a few primitive people gathered around the campfire from last night, a large pile of burning ashes, and Anna was leading people to rummage through something.

Oh, by the way, Lin Yuan suddenly remembered that he put a few clay pots made of clay in the fire yesterday afternoon, and he didn't know how it burned, he was so busy this morning, he forgot about it.

"Wow!! Look, King Yan! ”

Anna spotted Lin Yuan coming over and smiled and held up the loot she had unearthed.

It was a dark, jar-like object, covered in burned ashes.

Lin Yuan took the jar with a smile, he wiped off the black ash on it with animal skin, the orange-yellow clay pot on the ground was exposed, Lin Yuan tapped it lightly with his hand, the voice was dull, and it seemed to be relatively hard.

It seems to have really been burned into pottery?

Lin Yuan instructed everyone to take out all the pottery in the ashes, wipe off the dust, and put them in the sun.

There were 5 pottery works of different sizes, the largest one was the big-bellied and small-mouthed container made by Lin Yuan using the method of coiling with mud rope, and the other few were containers pinched out by other primitive people, a large plate with a wide mouth, and the other few were some bowl-like things, but they looked crooked and had no beauty. There is also something that I don't know what it looked like, but because of the baking, it was broken into pieces of pottery.

Even these flawed works of art amazed these primitives.

They saw how these things had turned from mud to hard pottery, and one by one they thought it was a miracle.

"King Yan Vulcan is above!! Great miracles!! ”

One of the primitives took the lead and lay on the ground, and the rest of the primitives hurriedly lay down and shouted.

Lin Yuan shook his head helplessly, he looked at Anna, who was smiling shallowly, and she said softly:

"Looks pretty good!"

Lin Yuan scratched his head, walked over, picked up a few pottery, and looked at the sunlight carefully, from the appearance, these pottery seems to have the characteristics of solidification and molding, but it feels rough, it is estimated that the reason is not enough fire, the clay is not completely sintered, Lin Yuan vaguely remembers, it seems that the high school department said that when the temperature of the fire reaches a certain level, there will be less enamel objects, in this way, the surface of the pottery will be much smoother, and it will be more durable.

What is the approximate temperature? Lin Yuan racked his brains and didn't come up with it, maybe it was more than 1,000 degrees, anyway, it needed to be very hot.

It seems that if you want to make perfect pottery, you need to use a special ceramic kiln.

However, at the moment, these experimental products may be able to be used in a flexible manner?

Lin Yuan ordered someone to fill the pottery with water and put it on the fire.

When he saw that the pottery was not leaking, he let go of his hanging heart, and then he ordered the fire to be lit.

The raging fire constantly heats the water inside through the pottery, and the two substances that were originally incompatible with water and fire are perfectly combined through the pottery.

Unconsciously, some primitive people who had no work in their hands for the time being formed a big circle, and they all looked at Lin Yuan's experiment, all the primitive people's eyes were as big as walnuts, they had never seen water and fire put together, as if they were waiting for the moment to witness the miracle.

After a long time, the water in the pottery began to tumble, and then a large amount of white heat came out.

"Wow, wow, wow, wow!!"

A few primitive children who were relatively close to each other screamed, they were amazed at why the water had become like this, and thought that Lin Yuan had applied some kind of magic.

The primitive people who were a little farther away couldn't help but take a step back, if they hadn't known that this was something invented by the chief himself, I'm afraid they would have raised their stone spears and prepared for defense.

Lin Yuan smiled slightly, slowly raised his hand, and signaled everyone not to panic.

Then he raised his hand and threw in a few pieces of wolf meat, only to see the hot water splash everywhere.

"Everyone be careful, don't touch the water, this is boiling water, called boiling water, it will burn if you touch it! It's like hitting fire, you know? Anna said with concern on the side.

The surrounding primitive people nodded their heads, and the water after contact with the fire would become as hot as fire, and these primitive people could still understand this logic.

Lin Yuan looked at the water vapor and began to be in a daze, he seemed to think that for human beings, it was first discovered that water heating would produce steam, and until the power of water vapor was really used to develop the steam engine, how many detours did human beings take to achieve industrialization? With the interference of his Lin Yuan's factor, will it speed up this process?

So, if he speeds up this process, will he affect history again? Affect the timeline? So, can't he do that? In comparison, he was sent to eliminate the interference factor of time and space, if he established the interference factor, wouldn't he be regarded as an enemy by other time-travelers?

This was a dead knot with no results, and Lin Yuan decided to put this idea aside for the time being.

He looked at the tumbling pieces of meat in the pottery, and the roasted meat foam, the color of the meat had changed from blood red to brownish white, and it looked like the meat was cooked.

A strong smell of meat began to fill the air, this aroma was different from the smoky barbecue smell of barbecue, but another taste that had never appeared before, for primitive people.

The surrounding primitive people stuck their noses out and sniffed in the air.

"Lord Yanwang! Good...... It smells so good! What is it? Hou Yi boldly stood in front of everyone and looked at the contents of the pottery curiously.

Lin Yuan smiled slightly and said:

"It's stew, it's my new invention, go ahead, gather everyone, well, yes, and those carved wooden bowls in my tent, yes, the ones I asked you carved, take them all out!"

Hou Yi ran out happily, and after a while, he ran over with a large pile of materials carved out of wood.

Those were all things that Lin Yuan had carved out of old elm wood on a whim, and he had been looking forward to one day making these tableware come in handy, but he didn't expect it to be realized so quickly.

Lin Yuan stood up, asked for a bowl of broth with a soup spoon, blew it with his mouth, and handed it to Anna.

"Come, how about a taste of our green, pollution-free, pure and natural wolf broth?"
