When I woke up, it was already daybreak.

Xu Xin looked at his calves and arms, wiped off the dried herbs on them, and the scratches had completely disappeared, as if he had never been injured at all.

"This hemostatic grass is really useful." Xu Xin exclaimed.

It turns out that the medicinal herbs in this world don’t have such quick effects.

As soon as the sky brightened, he quickly got up and walked out of the cave.

Even though he was in the novice protection period, he was still subconsciously nervous about the cave and chose to escape as soon as he woke up.

After eating apples and berries for breakfast, Xu Xin returned to the stream and walked downstream again.

As we walked for a day, the stream was no longer the small stream it was at the beginning. It gradually became wider and the water depth reached about one meter.

There were many fish and shrimps in the water, which made Xu Xin very envious.

However, he still did not waste his energy on this. The top priority now was to find fertile soil.

Along the way, apart from seeing five pieces of ordinary soil, the rest were all barren soil, which made him feel very strange.

I have been walking for so long, but I haven't seen fertile soil, let alone other survivors who don't have the ability to create.

It is basically impossible to find fertile soil by feeling, and even ordinary soil is very difficult, unless you have the same ability as him.

After all, green-grade soil is also scattered.

Could it be that this world never intended for them to build high-end tree houses?

Thinking of this, Xu Xin suddenly became interested.

If he could find fertile soil and grow a high-end tree house, wouldn't that mean that his starting point was much higher than that of most people?

It's stable.

Try to find fertile soil today.

He doesn't want to sleep in the open air anymore, he wants to live in a tree house.

As he continued walking, Xu Xin began to think about the patterns of soil and these materials.

So far, he has only seen two colors, white and green, and white supplies are one level lower than green.

The five pieces of ordinary green-level soil he had seen were all discovered after the discovery of green-level plants, because those green-level plants grew in green-level soil.

But not all green-level plants grow in ordinary soil. Some of them also grow in white-level poor soil.

In other words, poor soil (white) is likely to grow white-level plants, but there is also a certain chance of growing green-level plants, while ordinary soil (green) currently only grows green-level plants.

Perhaps, green-level soil also has the potential to grow more advanced plants.

While thinking, suddenly, a wide green appeared in Xu Xin's vision.

His eyes immediately lit up and he felt delighted.

Could it be...

He quickly ran forward and looked towards the place where the green light was coming from.

When he saw the location where the green light was coming from, he was overjoyed.

"It's a lake! I knew there was a lake!" Xu Xin became excited and quickened his pace.

The area around the lake is much flatter than that around the stream, making it more suitable for settling down.

And since there is a lake, the surrounding resources must be abundant, and maybe we can find a fertile soil.

Xu Xin trotted and soon reached the edge of the lake.

Looking at the rippling lake and the finally widening view, he breathed a long sigh of relief, feeling relaxed all over.

This lake is really big!

Of course, it cannot be compared with the big lakes where big rivers converge, but it is about the size of an ordinary small reservoir.

The lake water is very clear. It looks deep in the middle, but the lakeshore is very shallow. Various fish and shrimps are swimming in the lake. There are patches of reeds growing by the lake, and there are lotus leaves and lotus flowers on the lake. If it weren't for the current situation, Xu Xin would even feel like he was in a park.

[Reed (green): A plant that grows near lakes and seems to be a material for making some kind of tool.]

Lotus root (green): A food that can be eaten raw or cooked.

"Good stuff!" One kind of raw material, one kind of food, this place is really the best choice for settlement. But is there any fertile soil around here...

Looking around, suddenly, a blue light appeared in his vision.

"Blue light!"

Xu Xin's eyes lit up and he ran straight towards the blue light.

The blue bushes are only a few dozen meters away from the lake.

Red Berries Large (Blue): A fruit that can be eaten directly, with a sweet and sour taste. It has the effect of improving eyesight. Eating it can increase night vision for 2 hours.

Xu Xin was shocked again: "Blue-quality red berries... can have such effects?"

However, these are not the main points. He slowly looked down...

[Fertile Soil (Blue): A fertile soil, rich in organic matter and other nutrients, rare even in the jungle.]

"Beautiful!" He clenched his fist excitedly. Finally found it!

After calming down, he didn't rush to plant, but walked around the lake.

He wanted to see if there was any other fertile soil.

However, to his disappointment, at least the area around the lake seemed to be the only fertile soil.

There is a lot of ordinary soil, much more than before by the stream. Basically, nearly half of the soil is green-level ordinary soil.

At first glance, the proportion of green is not much less than that of white, and there are also a few scattered blue spots, which are blue-level plants growing in green-level soil.

His guess should be correct. Soil of a certain level can not only grow plants of the same level, but also has a certain probability of growing plants of a higher level.

It seems that places like this lake are the suitable areas that survivors are looking for to plant tree houses.

Although there is only one piece of fertile soil (blue), there is ordinary soil (green) everywhere. As long as you find such an area, you can at least minimize the probability of growing a "low tree house"!

After all, the name "low tree house" gives people a sense of insecurity just by hearing it.

After spending a lot of time trying to find no blue-level soil, Xu Xin stopped wasting time.

He returned to the original blue-red berry plant and picked all the large red berries, 32 in total.

Then he hesitated and tried not to dig up the bush. Instead, he dug a small hole next to it and planted a walnut-sized tree house seed.

After all, this piece of land is about one square meter in size, and half of it has no plants growing on it.

[Tree house seeds planted successfully, 2 hours of growth time remaining]

[Wild plants growing in the soil have been automatically cleared.]

The first hint made Xu Xin's eyes light up, but the second hint immediately made him deflated.

It doesn’t work. It seems that a piece of soil can only grow one kind of plant.

The [Red Berry·Large] bush disappeared without a trace in an instant. At the same time, a small seedling emerged from the soil and began to grow at a speed visible to the naked eye. Within a minute, it grew into a small sapling.

Xu Xin was amazed. This growth rate was truly amazing.
