After I lost my job, I started to get rich from plane trading.

It seemed that nutrition was in place, so the tree, which had some changes in its leaves after absorbing pollutants, started a new movement.

Through the transparent isolation box, Su Nianwei watched the root system under the soil continue to move, densely intertwined with each other, and the well-developed root system quickly filled the entire box.

Su Nianwei felt from the bottom of her heart that the box was filled with soil just now, but now the box was filled with the root system of the tree.

Above the ground, the originally dark tree trunks gradually began to fade, revealing dots of brown. These brown dots were scattered throughout the trunk, then expanded little by little, gradually swallowing up the black areas.

The leaves that had absorbed pollutants began to change, and the unknown objects produced after decay began to change.

It was still sticky and sticky just now, but it became dry and hard when the trunk changed. Then, like pieces of wall covering that was about to fall off, half of them were attached to the trunk. It seemed that as long as someone poked them, they would fall off. It will break open and fall.

The black color on the leaves has completely faded, and the old leaves that have grown up remain dark green, while the new leaves that have sprouted are a clear early summer green.

Su Nianwei waited for a while, until the tree growing in the box showed no obvious changes, and then went up to measure the data of each part of it.

She took some samples from various parts of the tree and collected them together with the samples she had taken before, so they could be tested together when she returned.

However, what is puzzling is that the girth of the tree trunk has not changed at all.

Isn’t this long?

Or does it focus on purifying itself?

In order to figure out this problem, Su Nianwei repeated the actions just now, changing three isolation boxes in a row and adding soil several times. She didn't stop until there was no larger transparent isolation box in her hand.

After all, this kind of transparent material that can isolate pollution is not easy to find. Except that they didn’t know the collection and compression technology at the beginning, so they needed large isolation boxes. Nowadays, ordinary isolation boxes are not big.

When people at the base go on missions, they will collect them and compress them into a small thing, so it doesn't need to be very big, and sometimes it can even fit in a box.

But having said that, it was quite useful for her to spend so much energy.

At least she found that after the tree suppressed the pollutants in its roots, the added soil became the driving force for its growth.

The trunk of the current tree has successfully grown from the thickness of a baby's arm to the width of the mouth of a bowl.

Perhaps due to the variety, under the dense canopy of the banyan tree, strips of aerial roots hang down between the branches. They are thin and look extremely soft. If there is wind, they will sway with the wind.

However, Su Nianwei, who had seen the ferocious appearance of its roots under the soil, would not underestimate these banyan whiskers. She had seen it. She had not paid attention when pouring the soil and dropped a stone. She was stunned by these aerial roots that had grown to touch the ground. Broken.

Regarding the greatly changed tree in front of her, Su Nian was slightly surprised by its growth rate. She just looked at her inventory. Well, she had to pour at least two trucks of nutrient soil.

She will use this soil to grow grain, and the nutrients contained in it can feed three or four crops of grain.

It’s just...why does it grow horizontally?

Su Nianwei compared the distance between himself and the tree crown and found that there was not much change.

The tree was almost as tall as her when she was brought here, and it is still the same now.

The key is that when she added the soil for the last time, the system said that the tree's absorption had reached the limit. Before it had digested the nutrients just now, it was useless for Su Nianwei to ask you to add more.

So there was no lack of nutrition, but Su Nianwei remembered that Mo Qinglan said that the seedlings he planted were always growing taller, so why did they only grow "wide" when they reached her hand?

It can't be that she has the talent to make trees "fat", right?

Looking at this tree dedicated to horizontal development, Su Nianwei fell silent.

The system doesn't care about her complicated heart. After all, it takes energy and has to do things for people. Now that it has collected the data, it has started to make comparison charts.

Of course, it did not forget the group of unlucky ones who were tortured to the point of crying in the Universe Mirror. When they were about to lose control or succeeded, it reminded Su Nianwei to release them.
