This story explains the production method of konjac very well: the konjac powder of konjac stems is soaked and cooked with alkaline water from plant ash, which can remove the toxic substances in it.

After boiling, the resulting solids are put into a drained container and drained, and konjac tofu is obtained.

In later generations, when making konjac tofu, gypsum was added.

The specific reason is not clear to Wang Tian, it is estimated that it is the same as making water tofu, gypsum can more effectively solidify and expand the volume of konjac.

Although he can't eat enough, it is also a kind of food for the future generations, and Wang Tian will certainly not let it go.

He had all the plants on the ground cut down, then the stems from the ground were dug up, and the people carefully wrapped them in broadleaf leaves and brought them back to the tribe.

Although konjac is not enough to eat, it can still be used to deceive the stomach. The fibers in his body can swell 80~100 times after absorbing water.

The root of a konjac tree can make konjac tofu that can definitely surprise people. Although it doesn't care about being full.

"This is a good thing, you can eat it, I'll make konjac tofu for everyone when I go back."

Second Brother King Kong doesn't know why he still digs this plant in the middle of the day? This thing has been itching for a long time when it touches the skin, and when he heard that the Son of Heaven was going to say that it was going to be eaten, the second brother shuddered when he thought about it.

He hurriedly explained to the Son of Heaven: "The Son of Heaven really can't eat this, it will die!" ”

Wang Tian smiled, "I have a way to make it edible, don't worry that I won't make fun of the tribesmen." ”

The second brother will be suspicious, he has a deep understanding of the horror of konjac, but the Son of Heaven is a person who can make delicious salt in the stones, and these experiences tell him that the decision of the Son of Heaven should not be denied.

All the konjac stems in the world were dug out and carefully held in front of their chests, and the action was like holding a bomb. It can be seen how the former konjac made them sour.

Wang Tian is not afraid of digging up the konjac. This thing can sprout with just a little bit of skin.

The group went straight back to the tribal cave, where they had unloaded the limestone in front of the factory.

In the afternoon, the kiln could be fired, and Wang Tian was anxious to ask Wu about the Water Tribe. He was never too relieved about the tribe's proximity to his own tribe.

"Wu, what kind of tribe is the Water Tribe?" Wang Tian hurriedly asked after finding Wu.

Before, he asked the second brother to inform Wu about what happened to the quarrying today.

"When this tribe was in the last snow season, our tribe went to their department, and the number of adults was not as large as that of our tribe, only five full tens."

Wu gestured with his hands as he spoke, "50 adults, then they can be regarded as pouring out of the nest today, is it really because the tribe is flooded?" Wang Tian raised his concerns.

"This should be true, the rain two days ago, I have seen it a long, long time ago."

Wu replied in the affirmative: "The cave of the River tribe is on the cliff by the river, and it is indeed possible to flood their tribe's cave entrance with such heavy rain,"

In Wu's explanation, Wang Tian figured out the cave situation of the River tribe, and like his own tribe, the River tribe lived in danger.

In front of the entrance of their tribe's cave, there is only a small staircase, which is connected to the outside world through a path in the rock wall.

The mouth of the tribe's cave is very wide, but it is only three meters from the river.

It is not surprising that the river is flooded when the water is surging.

After getting a clear answer, Wang Tian was relieved.

"Do they live by the river and fish with nets like we do? They have the same bamboo raft as we did. Wang Tian asked further.

Wu shook his head, "I don't know if I used a net to catch fish, maybe they do, but they don't want me to see it." ”

Wu said uncertainly, in his opinion, the fishing net is an artifact, even if the River Tribe can use it, he will not let himself see it.

It is human nature to protect food, let alone a person like Wu who is wise and always thinks about the tribe.

It's understandable that you want to learn from other people's strengths, but you don't want to share your own achievements.

Just as Wang Tian is unlikely to reveal the secret of pottery at this stage.

"There are a total of 50 adult populations, and the level of civilization is about the same, so it can't pose much of a threat to the ministry itself." Wang Tian was relieved when he thought of this.

After noon, ten adults continued to fight the horses, and the rest of the people began to build the lime kiln first.

The amount of small stones fired at the quarry point cannot meet the needs of building the wall, and it is not possible to burn these large stones without two or three days.

This requires guarding the kiln to add firewood, and it is necessary to spend the night outside the cave, and the safety of the night is near the tribal cave, with the protection of the horse rejection, and the fire, there should be no problem.

First of all, it is necessary to reject the horse to be in place, so this afternoon to build the lime kiln and plate the firewood, wait until tomorrow morning to burn the kiln, according to the horse before tomorrow day, it will be done.

On the side of the factory, they piled up a circular kiln with a diameter of five or six meters with made bricks, leaving only a small square hole at the bottom for ventilation and observation.

In the kiln, a cog-shaped pile of limestone was piled up, as it had done this morning. There is a gap between the stones. It facilitates the flow of flame and heat, so that the overall temperature in the kiln is kept consistent.

The gear notch corresponds to a ventilation and observation strand. While stacking stones, wood is filled as a material for the kiln.

After the stone collected today is used up, the lime kiln of about one meter and a half in a city will be plated.

In fact, the outer layer can be directly used with stone disks, but since there is no coal as fuel, fuel needs to be added continuously during the kiln firing process.

This does not make it possible to add fuel all at once to ignite the lime as in later generations. Moreover, with uneven stones, it is necessary to create a neat wall, which seems unlikely for the inexperienced Wang Tian and others.

If the kiln collapses during firing, it's a big deal.

And the red bricks need to be burned anyway, so that there is no waste of materials.

After the lime kiln is coiled, the next step is the brick kiln.

Brick kilns are similar to lime kilns, but because of the fuel. The brick kiln is coiled 3.5 meters higher, and the interior rotates in a circle.

There are bricks connected between the rings, and the firewood holes between the bottoms will run through the three rings, and the method of filling fuel up and down is adopted.

This is different from lime kilns. The height of the lime kiln allows for easy fuel filling from the top.

For this reason, the height of the ventilation hole and the firewood hole on the side of the brick kiln are 40 cm.

With the experience of loading the lime kiln, the speed of the brick kiln was significantly accelerated, and Wang Tian handed it over to everyone after explaining it clearly.

He began to process the konjac stalks that had been dug up by the crowd today.

Go back to the tribe and bring a stone knife, combine the konjac rhizome with the branch, and use the stone knife to cut two centimeter-thick slices.

Thin slices of plant ash are applied to the wound, then piled up at the base of the cave wall, and the entire area is covered with plant ash.

After the beginning of spring, you can germinate by simply taking it out and planting it.

Put all the konjac into three back baskets, take it to the small waterfall below the pond and let the water wash away the surface of the sediment, and then you can peel it with a bamboo knife.

In order to prevent skin allergies caused by contact with konjac, Wang Tian first had to make a leather glove from the old animal skin that had been dehaired to facilitate the subsequent work.
