Looking at the willow branch that was rooted by himself, Li Meng's little face was full of surprise, and he obviously felt that he still had some strength left, you know, if you used it casually before, you would be weak.

Subsequently, Li Meng planted the rooted willow branches on the ground at will, and then buried them in the soil, maybe it won't be long before they will grow into a new willow tree.

Lao Bi looked at Li Meng and said, "This time the promotion is a bit fierce, but it shouldn't be so fast after that." ”

Ren Hai nodded, happy for her sister, but she didn't seem to be able to have too strong lethality and self-protection ability.

Li Meng's ability is very strange, it is said to be a healing system, but it is actually very general, and in general, it can restore the life state of a life.

In short, it is a normal person, the life state is 100, when it falls to 80 when it is injured, and it is 10 when it is dying, Li Meng can add life status to them, theoretically speaking, as long as it is not completely dead, Li Meng can save it.

It's just that the consumption of this is different, and the ability to consume near death is much higher than that of injury.

After sorting out his emotions a little, Li Meng bowed to Lao Bi gratefully, and then said, "Thank you." ”

Li Meng's thanks come from the bottom of her heart, now she can finally help her brother a little, when her brother is in crisis, or when she is injured, she has herself by her side, even if it is very weak, but now she can do something.

Lao Bi waved his hand, indicating that he didn't care.

"Why are you talking about this, after all, I grew up watching." After finishing speaking, Lao Bi turned around, and the corners of his eyes were also moistened.

This kid, what are you doing with such sensational words, I am definitely not moved.

After a brief tidying up, the three of them set off again, because the water upstream was relatively turbulent, the lake Li Meng could not pass, and walked to the east for a while, until the river was no longer turbulent, and then continued to go south,

After Ren Hai and the others left, a figure appeared where they were standing

A few days later, on July 9th.

Specks of light shine through the dense foliage on the ground, forming round spots one after another.

In fact, no matter what the shape of the transmitted light is, as long as it exceeds a certain distance, the light spot projected must be circular.

Ren Hai followed Lao Bi and walked in this hundred-tree forest for several days, looking at the dense leaves overhead, Ren Hai felt a little stuffy, noon, and almost into the middle of July, some heat is inevitable, if it is not in the forest, but the Gobi, I am afraid it will not be able to withstand it.

Along the way, I encountered many clones, constructs, and a few wilderness outcasts, but due to the existence of Lao Bi, there was no danger in the end.

Every time he encounters a small danger, he will solve it by himself, and if he can't solve it, Lao Bi will take action.

In fact, Ren Hai didn't do anything, but they would still be besieged and killed by the clones, not because Ren Hai offended them, but because of the hatred between species.

And Ren Hai's evolution value has reached the point of 97, and the evolution value has grown very slowly these days, far less rapid than before, for Ren Hai, I don't know if it's good or bad, after all, this is the first time Ren Hai has experienced this kind of thing.

At this time, they have traveled to a place dominated by shrubs, mostly sand dates, which is very difficult to see, after all, in this forest dominated by trees, it is difficult for shrubs to reproduce and survive.

However, judging from the location of these date shrubs, they should also be artificially planted.

"Don't look at it, you take a closer look at the soil on the ground and dig down." Lao Bi observed Ren Hai's movements and spoke.

Afterwards, Ren Hai took out the dagger placed on his calf, and then used the dagger to dig up the fallen leaves and weeds covering the ground.

After watching it for a long time, Ren Hai didn't see what kind of doorway there was underground, could it be that what Lao Bi told him was not a problem?

It should be like this, I wonder why it is all shrubs, all sand dates, and arbors, but they are not particularly vigorous.

If it's just a small problem, then it's understandable, after all, it may be because of water quality and so on.

"Don't you see it yet? This forest is mainly sandy, and in the beginning, it was a large sandy land, and not only that, but it was also saline-alkali land, so only the vegetation that is very resistant to stress and has good windbreak and sand fixation can only be planted. ”

"Tall trees such as poplars, although they have a strong ability to retain water, do not have much sand fixation, and it is difficult to grow into a big tree in saline-alkali land, and their growth will be limited after a certain number of years, and finally die."

After Lao Bi finished speaking, he looked at Ren Hai, as if a teacher was teaching a student.

"I see." Ren Hai nodded thoughtfully.

It's no wonder that when I was digging, except for some rotten leaves, the soil was basically sand, and at first glance it felt like it had very few nutrients.

It seems that planting should also be divided into soil quality, I knew before, but only vaguely know, and for tall vegetation like trees, I know even less, in the illustrated book, there is also the vegetation of S. samphibe, saying that S. spp. has many advantages and basic information such as stress resistance.

But this doesn't make Ren Hai know everything, if that's the case, then those people in the city don't have to go to school, just send a set of books, and they will all be there.

What is missing is the way of thinking, the ability to understand.

"It's much better now, there used to be no trees here, and only the highly resilient vegetation can barely survive."

"After so many years, all kinds of fallen leaves and natural self-regulation, the soil quality has become much better, not so barren, after all, the final direction of these fallen leaves is humus, and then fermentation to produce humic acid, and the role of humic acid is to change the soil structure and improve soil quality." Lao Bi seems to have more words today, and there are more wrinkles on his brows.

The tightly knit brows are always conveying some information to Ren Hai, and Lao Bi must have hidden many things in his heart.

Although Ren Hai didn't understand what Lao Bi said, he still remembered it firmly, and these came from a very experienced person.

Lao Bi looked up at the sky, then found a position and stopped, looked at Ren Hai and said slowly, "You stay here first, I'll do something first." ”

After finishing speaking, Lao Bi slowly left towards the west, leaving only Ren Hai and Li Meng.

Ren Hai disposed of a vacant lot, set up a shelf, and prepared to bake the brown dough cake a little before eating, after all, if you often eat cold things, your stomach will not be able to bear it.

When the two finished eating, Lao Bi still didn't come back, and Ren Hai began to be a little anxious.
