Chen Zhe quickly made several clay bricks with the materials on his hand, and then marked them with serial numbers, carefully recorded which materials they were made of and what proportions they were made of, and then placed them in a ventilated place to dry naturally.

After the bricks were dried, Chen Zhe began the firing work.

Place these bricks neatly in the brick kiln, place enough fire, light a handful of fire, and then seal the kiln opening of the brick kiln, leaving only a ventilated flue for a long time to fire.

During the firing process, Chen Zhe waited nervously because he was completely trying his luck in the preparation of clay brick auxiliary materials.

Except for the clay content in clay bricks is about 35%, he has no idea about the reasonable ratio of clay bricks. Because the clay on the islands is different from the clay on the mainland, some of the ratios recorded before may not be used on the clay on the islands.

The time for firing clay bricks is shorter than that for firing pottery, and it is finished this time before dark.

Chen Zhe couldn't wait to dig the earth kiln, wait for the inside to cool completely before taking out the clay bricks.

But in fact, it is not necessary to completely remove the bricks inside. Chen Zhe has seen some results - among these clay bricks with different proportions, at least half of them have broken during the firing process, and a small part of them has not cracked, but the surface is covered with cracks.

This shows that the ratio of this part of the clay bricks is definitely wrong, and the bricks burned with this ratio cannot be used at all.

Seeing this scene, Chen Zhe felt frustrated.

Yan'er thoughtfully patted Chen Zhe on the shoulder and whispered: "It doesn't matter Brother Chen, this is just the first time I tried it."

Chen Zhe nodded slightly, but his heart was not as calm as he did.

It is fake to not burn high-quality clay bricks, so it is not a hurry. After all, Chen Zhe lives in the wilderness, and many wild animals on the island are eyeing the food on his camp. If he builds brick walls one day later, the camp will be more dangerous one day.

In addition, the rainy season is coming. When the rainy rainy season comes, burning bricks will become an impossible task. If Chen Zhe cannot burn a batch of qualified wall bricks before the rainy season comes, then his plan to build the wall will be completely ruined...

After thinking about it, Chen Zhe felt stressed.

After a while, the temperature in the brick kiln finally dropped. Chen Zhe took out the clay bricks that were not broken or cracked yet and looked carefully.

There are only three surviving clay bricks, and two of them are very complete, but because of the too much clay ratio, it actually has the texture of pottery when burned. When you knock it, it will break if you touch it.

This certainly doesn't work.

The last piece was too little clay, which made the whole brick too crisp, like a piece of scattered cake. When it touched the surface, it would fall all over the floor.

So the last three bricks failed to meet Chen Zhe's requirements, and this batch of clay bricks was "annihilated".

Chen Zhe sighed helplessly and put down the waste in his hand.

Netizens in the live broadcast room also saw this scene, and everyone couldn't help but regret Chen Zhe.

"It looks like it's really hard to burn bricks..."

"Didn't Teacher Zhao just say that the debugging ratio is very complicated and it won't work for a week."

"Chen Zhe didn't cry, stood up and stroking!"

“Failure is the mother of success.”

"If you don't have it today, try again tomorrow!"

“…”

Host Zhu Ranran also said with great regret: "It seems that Teacher Zhao is right. Chen Zhe's batch of bricks have all failed."

Zhao Mingliang nodded without surprise and said, "It is expected and reasonable. Chen Zhe still has a long way to go to burn successful clay bricks."

Zhu Ranran sighed and took the initiative to say to the director: "I think we can take a look at the survival of other players in the group first. It seems that Chen Zhe will not burn the clay bricks that have succeeded today."

On the director's team, the director thought so. He immediately switched the camera and transferred the picture to other survival contestants.

...

And here on the brick kiln.

Although the first batch of firing ended completely in failure, Chen Zhe was not discouraged.

He did not give up on burning clay bricks.

However, the first failure also taught him a lesson and made him understand one thing - trying the ratio of clay bricks without any clues is like a blind man crossing a river. Using this method to burn bricks is not that he doesn't have the chance to burn high-quality clay bricks, but the chance is too slim.

In this case, even if a qualified wall brick is burned, it will definitely be a big fortune. He has no time to hit the big fortune again and again. He has to build the wall before the rainy season.

Since the traditional method is not good, Chen Zhe thought of a non-traditional method - the item upgrade system.

If you can't burn high-quality clay bricks, then use the item upgrade system to upgrade a high-quality clay brick.

Thinking of this, Chen Zhe first made an excuse to send Yan'er, Qiao's sisters and others away.

"I think it's getting dark. You don't have to accompany me here. Go back and prepare dinner. I'll burn another batch of clay bricks and go back."

Yan'er and the others didn't know that this was Chen Zhe's "scheming to lure the tiger away from the mountain", so they obediently returned to the camp to prepare supper.

The photographer thought that Chen Zhe would not be able to burn qualified clay bricks for a while, and might not want to stand outside the brick kiln to eat dust, so he carried the machine and Yan'er and the others back to the camp.

After all these people left, Chen Zhe picked up a burnt clay brick and used the item upgrade system.

【Article detected: a clay brick of poor quality.】

【The current durability of the item: 17/50.】

【Item value: 0.7 yuan.】

[Does it cost 20 points to upgrade the item?]

Chen Zhe thought about it and did not directly upgrade.

Although the 20 points of popularity is not much, if you want to build a wall with hundreds or thousands of bricks in total, how much popularity is it?

Besides, when the bricks are burned, Chen Zhe can't burn out a kiln of broken bricks first, and then use the system to wave his hand to directly turn these broken bricks into high-quality good bricks, right?

At that time, Yan'er and the others will definitely see it and become suspicious.

So after thinking about it, the trick of upgrading clay bricks with the item upgrade system is too dangerous and easy to get rid of. Chen Zhe will definitely not be able to use it.

But this trick cannot be used, how can you obtain high-quality clay bricks?

Chen Zhe frowned, and then his eyes suddenly lit up.

A bold idea popped up in his mind.

He picked up a piece of brick that had not been burned, had just been pinched, and had moisture from the side, and then stopped his eyes.

[Item detected: a clay brick with incorrect proportions.]
