Bang Bang Bang! Ye Feng's fingers tapped on the tabletop, and his brows furrowed deeply.

This is indeed a problem.

And the problem is too big to ignore.

"Is there anything you can do, Chief?" He said to Taba.

Taba showed a very helpless smile: "I only found the problem, but I didn't find a solution to the problem." ”

Ye Feng once again set his eyes on everyone.

Everyone looked away, and it was clear that they didn't have any good ideas.

Ye Feng sighed softly and said, "This topic will not be discussed for the time being, let's talk about other issues!" ”

Then they began to discuss other matters of the tribe, and after more than an hour of discussion, the meeting ended in a hurry.

……

Six days passed quickly, and on this day the brick kiln was about to open, and Ye Feng hurriedly came here early in the morning.

Common bricks in life include red bricks and green bricks, and Ye Feng burned red bricks this time.

But in fact, Ye Feng prefers green bricks, because in his opinion, green bricks have a simple, elegant, calm, simple, and quiet beauty, which is nothing more than the white wall and tile spring, and the fragrance of green bricks and flowers is still in such an artistic conception.

But in the end, he still chose to burn red bricks, because there was one more step in firing green bricks, which made him too lazy to get it.

Clay contains iron, and when it is completely oxidized during firing, it produces ferric oxide, which is the red color we commonly use.

And if water is added to cool during the firing process, the iron in the clay is not completely oxidized, and it will show a cyan color, that is, green bricks.

It was this step of adding water to cool that made him choose to fire red bricks, which are all bricks anyway, and it is just a difference in color.

The tribesmen all heard that Ye Feng was making a new thing, and they all gathered around the brick kiln, wanting to see what Ye Feng had built such a big kiln and what it came out of in the end.

"Hey, did you think there's new pottery?"

"I don't know, don't ask me, ask someone else to go."

"It's a fool to ask this question, if it's really a new pottery, Ye Feng will do it himself?"

"Yes, if it's pottery, Ye Feng will only draw a drawing and let the people in the pottery team burn it."

“……”

The crowd stood in twos and threes, pointing at the brick kiln in the middle, and discussing.

Ye Feng directly ignored those people, anyway, when he was making something, he would always be watched like this.

He found a copper rod, poked a small hole in the entrance of the brick sealing kiln, and then tested the temperature with the palm of his hand against the small hole.

The feeling in the palm of my hand was warm, warm and not hot.

Ye Feng nodded and said, "Open the kiln!" ”

Barr hurriedly said, "Okay! ”

As he spoke, he hurriedly picked up the shovel excitedly and smashed the sealing mud that was drumming at the mouth of the kiln.

After the mud seal kicked up a large cloud of dust and dispersed, the black hole appeared in front of the clansmen like a monster with a big mouth open.

Ye Feng hurriedly walked in.

But then he choked on the dust inside and ran out.

It turns out that the air temperature in the kiln is high, and the air temperature outside is low, and when the mud is dug up, the two air contacts produce a large flow, which makes the dust in the kiln float up.

After Ye Feng ran out, he hurriedly blew his nose.

It's black, sticky, and exceptionally disgusting.

Fortunately, I have a little cold in the past two days, and I am running a runny nose, otherwise it would be irritating to inhale the ashes into my lungs.

When the dust fell, Ye Feng walked in again.

Since the light was too dark to see clearly, he groped his way to the stack of bricks, and felt it carefully with his right hand.

It's not hot, just a little bit of residual warmth.

So, Ye Feng walked out of the brick kiln with a brick, to see if one of the bricks was qualified.

Ye Feng looked at the reddish-brown brick in his hand and couldn't help but nod with satisfaction.

Not to mention the quality, Guan is that this appearance is already very similar to later generations.

The roots of the tree came out of nowhere, looking at the square red thing above Ye Feng's hand, and hurriedly asked, "Ye Feng, this is the brick you are talking about?" ”

Ye Feng was startled by his sudden appearance, and the brick in his hand couldn't help but slip, and hit the ground with a snap, almost hitting his feet.

Ye Feng was immediately shocked.

nnd, if this is sturdy and smashed on the foot, at least a week will not be able to get out of bed!

Thinking of this, he glared at him with a pair of bull's eyes and shouted, "When did you come here?" Also, how did you know this thing was called a brick? ”

The root of the tree couldn't help but blush, and hurriedly said: "I rushed over when I heard that Ye Feng was making something new again, I just learned from Team Leader Barr, this is all called bricks." ”

"Yikes! This brick ......" The root of the tree suddenly screamed, and quickly bent down to pick it up.

"It's okay, it's okay, it's not bad, it's not bad!" The root of the tree seemed to be holding a child, and hurriedly stroked the brick gently.

Ye Feng was speechless for a while.

These bricks, after all, are building materials, and their quality is related to the safety of the building, so it is important to inspect whether it is qualified or not, and its hardness.

"You, bring me a hammer." Ye Feng pointed to a clansman beside him.

The man nodded quickly, and turned to look for the hammer.

"Boom!" A large copper hammer weighing more than ten catties smashed in front of Ye Feng's eyes.

This is the hammer used by the engineering team to repair the house.

Ye Feng was slightly distracted for a few seconds, and then he broke down and shouted: "I don't want this hammer, you take a hammer!" ”

He looked at the face of the clansman, and it turned out to be the same thing that had brought him lard before.

When the clansman heard this roar, he couldn't help but be stunned and said, "I'll take a hammer?" I'm supposed to be a hammer, huh? ”

"You took the wrong thing, and you dare to talk back? Tell you to take a hammer, take the wrong hammer, and say 'you take a hammer' What is it, a hammer! There is a hammer in the brain! ”

The clansman was instantly petrified on the spot.

The crowd of onlookers stiffened.

"What do you mean?"

"It seems to say something about a hammer, and then a hammer, and then a hammer......"

"What kind of hammer are you talking about?"

"I don't know what hammer I'm talking about."

"You don't understand hammers, let's talk about a hammer!"

"Stop, don't say hammer again, who is talking about giving him a hammer!"

"You hammer! You yourself say the hammer! ”

……

Ye Feng, a heartless and lungless person, didn't know that his casual words had triggered the philosophical thoughts of the clansmen about hammers.
