Under Xu Xin's ability to identify these two banyan trees both emit blue light.

It's blue grade!

These two banyan trees grow in blue-grade soil, and are the only two blue-grade soils in this lakeside scene. The rest of the soil is green and not white.

The size of these two banyan trees is basically the same as the size of the second-level blue-grade tree house before the number of layers is increased. The tree canopy is dense and about seven meters away from the ground, and has many roots.

It's so much like a tree house.

Xu Xin immediately walked to a banyan tree and reached out to touch its trunk.

[Banyan (blue): A special type of tree, which can be obtained by cutting down. Although it looks like a very ordinary banyan tree, as long as there is a tree house within a 100-meter range, it can coexist with the tree house!]

It's not a tree house, but the introduction of this banyan tree is not ordinary at all!

Special types of trees coexist with tree houses within a 100-meter range!

Xu Xin's eyes widened.

The last time I saw the word symbiosis, it was the heart of the plant!

Symbiosis is not parasitic! To the heart of the plant, it can provide the tree house with very strong self-defense capabilities, and both sides are mutually beneficial!

Unexpectedly, these two banyan trees they suddenly discovered could also coexist with the tree house.

Moreover, Xu Xin is more sensitive to the words "special types of trees".

The first time he saw these words was in the introduction of the Blue-level Iron Axe, saying that the Blue-level Iron Axe can cut down some special types of trees.

Later he discovered that the tree house was a type of this special type of tree.

Now, this banyan tree is also. Although it is not a tree house, it belongs to the same species as the tree house, and it also belongs to a special type of trees. It can only be cut down with an iron axe above the blue level!

It's exactly the same as the nature of a tree house!

Xu Xin really couldn't help but guess, if it was planted next to the tree house, what would be the miraculous effect of this kind of banyan tree that looked like a tree house? Did they find another accessory for the tree house?

Will it bring a powerful ability to the treehouse like a plant heart?

Ji Chaoyang also touched the trunk of the banyan tree. After seeing the introduction, his solemn expression slightly relaxed: "It seems that it is just an ordinary banyan tree, not a tree house."

Ji Chaoyang looked up at the dense banyan tree: "However, I always feel that this banyan tree has a certain relationship with the tree house. Maybe we should dig out its seeds."

He was not as surprised as Xu Xin. He had no ability to identify. His introduction should not prompt the relationship between the banyan tree and the tree house.

However, he still noticed that this kind of banyan tree might have a connection with the tree house.

"It's indeed related to the tree house." Xu Xin looked at the banyan tree.

"...Oh, you can see your identification ability and a detailed introduction. What is the relationship between it?" Ji Chaoyang was slightly stunned by Xu Xin's affirmative tone, and then immediately understood.

"I can get a more detailed introduction. The introduction tells me that if this kind of tree grows within a range of 100 meters next to the tree house, it can coexist with the tree house." Xu Xin replied.

The canopy of this banyan tree is very dense, but he can still see the inside through the small gap in the canopy.

The canopy does not exist in the room of the tree house, but the branches of trees growing, and it looks like an ordinary lush banyan tree.

"Symosis? A range of 100 meters?" Ji Chaoyang turned to look at him. He also thought of the plant hearts. "How to symbiosis and let the tree house obtain new functions, can you know this?"

"I don't know." Xu Xin shook her head, "I just said that she could live in symbiosis with the tree house. However, I can speculate."

A scene of planting such banyan trees beside the tree house appeared in Xu Xin's mind.

If two banyan trees with dense crowns are connected...

Ji Chaoyang was silent for a few seconds and said, "Expand the area inside the tree house?"

Xu Xin nodded slowly: "...it's really possible."

Both of them felt it was very likely.

Their banyan tree canopy has never grown horizontally. Never once.

Under normal circumstances, banyan trees can grow to a large area.

But since they planted the tree house, the projection area of ​​the canopy of the tree house has never changed, but it has only increased the number of layers once.

The green-level tree house has always been about 25 square meters and the blue-level tree house is 50 square meters. The purple-level tree house of him and Ji Chaoyang is 100 square meters. Even if the tree house is upgraded, it only enhances the protection area, that is, strengthens the roots, but the size of the tree canopy and the area inside the tree house have never changed.

Therefore, for most people, the space inside the tree house is completely insufficient, especially the planting house. If you want to plant it in the tree house, the area is too small, and the single-story tree house is too short to let go of its hands and feet to plant, so you can only plant part of it outside the tree house.

Now that the weather is getting colder, there is only a small area outside the tree house to plant. Moreover, winter is about to begin. After the ice and snow come, it may not even be able to plant outside the tree house. In this way, indoor planting is particularly important.

If this kind of banyan tree can really expand the indoor area of ​​the tree house, it would be better.

"One person, one tree, how about it?" Xu Xin pointed to the two banyan trees.

Naturally, they cannot transplant such a big banyan tree. Even if it can be put into a backpack, it is only one-tenth of its weight, and it is not something they can hold.

They could only cut down and dig seeds. Two banyan trees were two seeds, just one person.

"I have no objection." Ji Chaoyang nodded, "Look at other resources first. If you do this kind of thing in the end, it is very strange here. If the action is too big, there may be special situations."

Ji Chaoyang was right, and Xu Xin thought so too.

He looked at the piece of orb placed in the crack of the stone wall. Everything here may be thanks to that thing.

That thing seems to be able to be taken away, but let's talk about it later. If you move that thing, it is the most likely situation.

Xu Xin looked down at the colorful flowers on the ground, squatted down, and gently picked one.

[Colorful Flower (Green): A beautiful flower. Planting in a tree house can improve the decoration of the tree house. The flowering period is seven days and withered after seven days. When the flowers are grown, the decoration degree increases by half, but it can permanently maintain the posture when it blooms.]

"Wow, this is a good thing!" Xu Xin's eyes lit up.

For him, a big demand for decoration, anything that can be added to decoration is a good thing, and his art room and alchemy room are still hungry.

He glanced at the entire colorful flowers by the lake.

"Well, pick them all and then dig them away." Xu Xin touched her chin and said to herself.

Although the upper limit of decoration for each tree house may be limited, and he can also create decorations by himself, it is a little more.

The more you get better!

Moreover, this kind of flower gives them the possibility of providing decoration to other survivors.

Their art room requires carving and creation by itself. Although it can greatly increase the upper limit of decoration, the current speed is simply impossible to mass-produce, and even the others in the explorers are not lucky enough to enjoy it, let alone other survivors.

But there is no problem with this kind of flower that relies on planting. After all, it will not consume their energy. Just plant it in the planting house to let it grow.

"I reminded me that this kind of flower can also be used to make pigments to make each oil painting more decorative." Ji Chaoyang also squatted down to pick a flower, and said in surprise.

Ji Chaoyang's ability to paint one of the [artists] requires paint. He has told Xu Xin before.

"Then this thing is also a good thing, and you should take it away when you leave."

Xu Xin has decided to dig the ground, take away all the flowers and trees here!

They are really good things.

He even reached out to pull out a few grasses, but unfortunately these grasses are not resources.

However, the best thing is the piece of the bead!

Xu Xin looked at the piece of orb that emitted soft white light and squinted her eyes.

"Yeah." Coco stood beside Xu Xin's legs, with his two little paws slashed his legs, and then pointed to the direction of the waterfall.

"What's wrong with Coco?" Xu Xin came to his senses, looked in the direction that Coco pointed, and asked in confusion, "Is there anything wrong with that small waterfall?"

The waterfall poured out from an almost horizontal crack on the wall, forming a not-so-large white water curtain.

Accompanied by the rustling sound of entering the water, coupled with the continuous swimming fish in the lake, and the soft white light reflected by the slightly tumbling water surface, the entire lake is like a fairy lake in the Taoyuan Fairyland, making people feel extremely comfortable.

Xu Xin even had the idea of ​​"How great it would be if I could live here."

"Yeah!" Keke waved his claws and gestured to Xu Xin.

Xu Xin understood the meaning of Coco, and his expression calmed down. He turned his head and looked at the small waterfall carefully.

"...You mean, there is still space hidden behind the waterfall?"

"Yeah!" Coco pointed his little head.

Because of the irregular water flow, the waterfall is white overall, completely blocking the view, and cannot see the scene behind the water curtain. In addition, this small waterfall is not big, so Xu Xin did not think about it in this regard.

Unexpectedly, this is actually a water curtain cave?

Could it be that there is some treasure in the cave?

However, the area ahead was completely occupied by this lake. If you want to go there, you can only go into the water and swim.

"The space behind the waterfall? Water Curtain Cave?" Ji Chaoyang also looked at the waterfall. His eyes opened, and he was a little surprised, "This is behind the giant's head, right?"

"That's right." Xu Xin nodded.

There is probably a secret about this giant's head hidden in the space behind that waterfall.

The two looked at each other and nodded.

Let's go and have a look. Both of them mean this.

They both jumped into the lake and swam over there.
