It was about to get dark, and Xu Xin quickly returned to his tree house.

He also planted the newly brought back [Parasite Tree House Seed] on the outermost periphery of his "back garden", but the previous [Parasite Tree House 01] was in the opposite position and planted on the other side.

No special consideration, he just felt more comfortable with symmetry.

While the parasitic tree house had not yet grown, Xu Xin sent a voice to Ji Chaoyang... He wanted to analyze the information today with Ji Chaoyang, and then consider whether it was time to tell the others in the explorer their inferences.

The opposite side was connected soon.

"I have met people from other districts." Xu Xin said straight to the point.

"...Oh?" Ji Chaoyang's voice across from the other side also became serious, "Which area is from that area."

"It's similar to your speculation, Jungle Zone 187."

“…are the neighborhood? Just the neighborhood.”

Ji Chaoyang was almost the same as him, because he was afraid that they were not just neighboring areas such as District 187 and District 189, but also a bunch of other areas. It was easy to deal with one or two areas. Many areas were melee, so the difficulty would be greatly increased.

Xu Xin told Ji Chaoyang all the information he got from Leyou.

"It seems that our speculation should be almost the same as each other." Ji Chaoyang was silent for a while and spoke.

"What did you find over there?"

"I also walked around the reserve and found two tree houses. Unfortunately, they both lost their owners and were on the verge of death. They did not meet living survivors."

"Have you found a problem?" Xu Xin frowned, "We haven't found people in this area, and there seem to be only survivors from other areas around us. Could it be that we are completely separated from people in the same area?"

He found three tree houses in total. Now, when he recalls, the location is even regular.

The first one is in the east, the second one is in the north, and the third one, that is, the one in the fun, is in the south. Although there are some deviations, they are all very different.

Each direction corresponds to a tree house, but these three tree houses are not the tree houses in their area!

If it weren't for seeing the lightning rod on Li Wenxi's tree house, he would have thought that there was something wrong with his position.

"This should be what I said before, cross-distribution." Ji Chaoyang pondered for a while and said, "All of us are separated."

Xu Xin naturally understood what cross distribution is. It was like black and white floor tiles.

The tree house reserve of every survivor in Jungle Area 188 is equivalent to a white square, while the survivors in other areas are black squares. The white squares are only connected to the black squares, and the black squares are surrounded by white squares.

In other words, producers in the same area can only be found in diagonal directions, such as northwest and southeast.

However, the protection area is not a square, but a circle, and the circle cannot be fully covered like a square. Between the oblique circles, there are dangerous areas that cannot be covered by the protection area.

Therefore, at least until the protection area continues to expand, there is no direct connection between the same area.

Now if you want to find people in the same area, you must go through the protected areas of survivors in other areas.

"I think we can tell them about this matter. We must establish a close group as soon as possible. Otherwise, once some people have bad intentions, some people will suffer." Xu Xin said. They are naturally referring to other people in the explorers.

"Then let's go tomorrow. Since the reserve can be interconnected, functions like the World Channel should be open. Let's verify it again today."

"good."

Xu Xin hung up the call.

At this time, the tree house had completely grown. Silver King and Mimi were both spinning around the tree house. It was the first time they saw a tree that could grow so fast, and they were very curious.

Xu Xin changed the name of this tree house to [Parasite Tree House 02], opened up some of its functions, and then took the four beasts back to his tree house.

He took out the two [Core of the Low Tree House] and prepared to use the core to upgrade the resources.

“What’s the best way to upgrade?”

The carving knife was temporarily put on hold. After all, even if he made a purple-level carving knife, with his artist level, he could not carve a purple-level statue. It doesn't make any sense. Maybe it's just that the carving speed is slightly improved, but his current speed is enough and there is no need to consume a piece of purple-level resource to improve it.

Weapons are actually a good choice. He can now upgrade two pieces of materials and make weapons. He has just obtained the strongest steel in his class. If he upgrades the steel block (blue) to steel block (purple) and uses the steel block to create weapons, he can obtain the strongest weapon in the purple level!

In this way, he is like his whole body is covered with purple-level equipment!

However, in terms of practicality, the one he should actually upgrade is the bone-removing knife, because the purple-level bone-removing knife can decompose purple-level materials, and the possibility of decomposing blue-level materials may increase.

After thinking for a long time, Xu Xin finally chose the weapon.

There are no beasts or mutant creatures around now, and I don’t know when they will appear. They may be left to the for a long time after they are made. Moreover, he hasn’t been to the west yet. After he is ready to assemble himself, he will go to the west to try it. Maybe another tree house core can be found there.

Eventually, he chose a steel spear in all his weapons, rather than a crossbow.

The purple-grade steel spear only requires two kinds of purple-grade materials, wood and steel blocks, while the purple-grade crossbow requires three kinds of wood, animal tendons and steel blocks. He can't make it now. Moreover, he now has powerful explosion arrows, and the firing rate and strength of the crossbow's crossbow itself is not that important, just enough.

[Steel pointed gun (green): A sharp gun made of steel blocks is sharper than an iron pointed gun. It is the hardest and sharp weapon in its class! Durability 1000. Requires wood (green)*5, steel block (green)*2]

The purple-grade steel sharp gun requires four pieces of blue-grade wood, a piece of purple-grade wood, a piece of blue-grade steel block and a piece of purple-grade steel block.

Taking out a piece of blue-grade steel block and a [core of the low tree house], Xu Xin tried to put the two resources together.

[Do you use the core of the low tree house to upgrade the steel block (blue) to the steel block (purple)?]

The prompt sounded, but Xu Xin did not hesitate and immediately chose yes.

The core of the tree house, which originally emitted a bright white light, suddenly shone brightly. Then, under his discernment ability, the blue light on the steel block gradually began to change to purple.

Finally, the light at the core of the tree house dimmed, and from a "night pearl" emitting bright white light, it turned into an ordinary light yellow spherical stone. The steel block also completely turned into purple.

[The core of the low tree house that lost its energy: the core of the tree house that consumed all its energy became an ordinary stone. Perhaps there is a way to make it full of energy again.]

Full of energy again! Sure enough, if you lose the core of energy, you can still recharge it again!

This made Xu Xin overjoyed. If he found this method, he could really produce purple-level resources by himself!

But how to charge it?

"The core of the tree house..." Xu Xin murmured to himself, "Could it be related to the parasitic tree house?"

He has seen all the functions of the parasitic tree house, and there is no option to charge the core of the tree house.

He suddenly thought that while he was operating in the parasitic tree house 01, Coco was scratching the floor with his small paws. When he finally left, it was still scratching the floor and was taken away by him. It was still a little reluctant at that time.

Xu Xin originally thought it was grinding his claws, but now it seems that...

No matter what kind of purple-level weapons, he could do it anytime. He picked up the cocoa from the sofa and rushed to the Parasitic Tree House 01.

"Yeah?" Coco was dozing off on the sofa and was taken to Xu Xin's shoulder, with question marks all over his little head.

"Let me see what's more special in the parasitic tree house."

"Yeah!" Hearing this, Keke was no longer sleepy and waving his claws and screamed, as if saying that it had actually discovered it a long time ago, but it was taken away by Xu Xin last time.

It's indeed similar to his guess?

When he arrived at the first floor of Parasitic Tree House 01, Keke jumped off Xu Xin's shoulder, ran to the middle of the tree house, and scratched the floor with his little paws: "Yeah!"

Xu Xin is very familiar with this location. Isn’t this the location of the trunk of the tree house, and the original location of the core of the tree house?

The parasitic tree house has no core, so it should be empty inside.

Could it be that the floor in the center of the tree house is pried open and the core of the tree house is placed in the original location of the core of the tree house?

Xu Xin touched the floor with her hands, but did not trigger any prompts to control the floor to lift up.

...Then chop with an axe!

Anyway, he just demolished a piece of tree house floor, and then demolished it. Afterwards, he didn't even have to repair it himself. He could recover it by relying on the tree house's own self-repair ability.

He did it as soon as he said it. He took out the iron axe and Xu Xin turned it to the floor.

"Click!"

The same as before, the green-level parasitic tree house faced the blue-level iron axe and was completely irresistible. With just one moment, the floor at the center cracked. After a few strokes, the floor cracked.

Xu Xin cleared the debris on the floor, revealing the situation under the floor.

"really!"

Under the floor is different from a normal tree house. A normal tree house is a hollow trunk, and the core of the tree house is buried in the bottom soil. The trunk of the parasitic tree house is indeed solid, with only a hemispherical groove, which can be placed in it.

【Discover the parasitic tree house charging slot, unlocking the core charging function】

Is this core charging function even discovered by yourself?

Xu Xin put the [Core of the Low Tree House] that had exhausted its energy. With a slight "click", the core of the tree house just got close to the hemispherical hole.

A faint white luster emanated from the already dim core of the tree house again.

Xu Xin touched it with her hands, and the core that became cold after losing its energy was warm at this time, like a hand warmer.

[Remaining charging time: 4 days, 23 hours, 59 minutes]

It can really be recharged!

"Yeah!" Coco also touched it on it, and finally lay on it, revealing a comfortable expression, and his little tongue spit out.

Xu Xin fell into thinking.

Originally, the core of the tree house provided energy to the tree house, but the energy of the parasitic tree house was obtained from the host tree house, so there was no need for special energy for the tree house core, but the energy obtained from the host tree house can be replenished into the tree house core.

This should be the principle of recharge the core.

However...it seems that the host tree house, that is, his tree house, needs to provide more energy and the burden is greater. I don’t know how many parasitic tree houses can withstand at most.

Although the five-day charging time is a bit long, the purple-level resource is worth waiting for such a long time.

If you have more parasitic tree houses in the future, then you can mass-produce purple-level resources!

By the way, what would happen if the core of full energy was placed on it?
