He was talking about bamboo salt, which is obviously the most suitable type of salt for toothpaste.

As for the production method, it is also very simple, that is, the sea salt is raced into the bamboo tube, mixed with the sea salt by relying on the original water in the bamboo, and filtered and purified after crystallization, and the result is bamboo salt.

Just do it, after Li Fei had a brief chat with Li Han, the two of them began to act.

In the end, after failing once, the two of them also succeeded in crystallizing the crystal clear salt from the bamboo tube.

Li Fei pinched a small piece and put it in his mouth and tasted it, his eyes couldn't help but light up, and he nodded excitedly, the taste is exactly like this, there is nothing wrong with it.

This familiar taste suddenly evoked some memories of Li Fei's childhood, and his eyes were a little blurry for a while.

The next step is to wait until the filtered and purified alkaline water has precipitated into a thick solid state, and this process continues until about the next morning.

Li Fei nodded lightly, and after mixing the salt into it, after half an hour of stirring, he finally made a preliminary toothpaste.

After a simple trial, the effect is really good, with the toothpaste made by Zhu Hao, everyone can finally brush their teeth after many days.

"Captain, it's really useful!!" Liu Keying was also very surprised and said to Li Fei.

The latter nodded slightly, after all, this can be regarded as a very great invention.

He made a lot of toothpaste again, after all, these things are not a hassle to get together, and their team is only this little person, and they don't use much.

So most of them were sent by Li Fei to Yixi, who was also puzzled when he saw this thing for the first time, but after trying it himself, he was full of praise for it.

So he naturally accepted a small gift from Li Fei with a smile, and at the same time, the two finally had time to sit and discuss the construction of the houses of the Litang tribe.

"Are you going to build a concrete house on top of the camp, or are you going to find another place to build it?" Li Fei asked seriously.

The latter didn't speak for a long time, and suddenly he was a little embarrassed, and after a long time, he slowly said, "To tell you the truth, we plan to choose another place to build a camp, and it is also in that forest."

"Oh?" Hearing Yixi say this, Li Fei suddenly had some surprises.

It is said that the relationship between the two sides is very good, and it is understandable that Yixi wants the two sides to be closer, but this reason alone is not worth the whole camp to move to the forest.

After repeated questioning, Yixi also told the reason.

"The ecology in the forest is so badly damaged, everywhere is bare, so recently I have been sending people to plant trees in the burned desolate area, but it is really time-consuming to go back and forth, so we thought about moving to the dense forest to live."

Li Fei only came back to his senses at this time, although their lives had been restored to normal, but the destroyed environment was impossible to regenerate.

In the past few days, Li Fei can often see a few natives carrying some small saplings that have migrated from here to plant trees in the forest.

Although it seems a bit like a remedial thing now, I have to say that these saplings will grow back into towering trees in a few years or even decades.

Li Fei can't guarantee that he will survive on this island for the rest of his life, after all, there are still some fantasies in his heart about going home.

However, the natives of Yixi's tribe have to live on this island for generations, so Yixi can have such a vision, and Li Fei is naturally more happy.

The main thing is that the soil in the forest is moist, which is more suitable for growing potatoes, and he has discovered this problem in the past two days.

Not to mention the dryness of this land of the Yixi tribe, the daily sunlight is too sufficient, according to Catherine's idea, it is not suitable for growing potatoes that can be fed by the presence of water

Vegetable.

So after thinking about it briefly, Li Fei nodded lightly and agreed with Yixi's idea.

The next step is the question of location, after all, there are more than 100 people in a tribe, and it is not easy to convince all of them to follow the migration.

It is also important that the new place has an abundant water source and is more convenient than this one.

So after a brief thought, Li Fei took Yixi to the field, and finally the two of them set the initial location around the natural pond where they had sheltered from the fire that day.

The water here is abundant, and in addition to the ponds, there are three or four mountain springs that can be used to connect fresh water.

And the place is big, the light is good, and the soil is suitable for growing vegetables.

The main thing is that this will allow the tribe to continue planting trees, because this is like a watershed for fire.

Since then, to the east, it is facing the half of the forest on Li Fei's side, where the fire has basically been more serious, and a large number of trees have been burned to ashes.

Since then, the west side has not been damaged much because the fire has become smaller, and most of the surviving animals live in the west, so the west direction naturally does not matter.

If they settle here, the communication between the two sides will undoubtedly be closer, and they can also reserve some private space for each other's teams, which is really in line with Li Fei's wishes.

Yixi doesn't know that much, but since Li Fei has already arranged the boards, he naturally won't have any opinions.

So after a simple communication, the two decided to carve out a place in this place as the address of the new camp of the Litang tribe.

Yixi was more generous, and directly agreed to lend Li Fei 50 people for the construction of a new camp.

This is even beyond Li Fei's imagination, after all, building a camp is not so simple, the amount of work is very exaggerated, and the time and manpower consumed are unimaginable.

With these fifty people, the problem of manpower can be solved, and Li Fei can be let go!

The most important thing is that this can also enhance the relationship between himself and the entire tribe, after all, the last time he passed through Rob's incident, there are still many people who are somewhat hostile to him.

This is naturally not Li Fei's purpose, he gives benefits to the Litang tribe every day, so that they are grateful to themselves, not hated themselves!
