Chapter 273 The Collapse of the Three-Story Tree House

Xu Xin went through the pile of things on the third floor again, but found nothing novel.

There were a bunch of tools on the ground, some were used for cutting and some were used for polishing. Xu Xin didn't understand these things either, but since they were tools, he put them in his backpack together with the semi-finished heavy crossbow .

This heavy crossbow seems to be close to the finished product, after contracting Ma Hongwei, let him continue to complete it, maybe he can get another good weapon.

After removing all these things, there is only a pile of wood and debris left on the entire third floor, and they are all green-level, and they are all worthless waste resources.

When Xu Xin came to the second floor, Lou Feier had already put all the decorations in the tree house into her backpack.

"Are there any special decorations?" Xu Xin asked.

"No, they are all very common. Green-grade crystals and mahogany in various colors are picked up during the rainy season." Lou Feier also took out a few gadgets and showed Xu Xin, "Other They are all trinkets bought from the points mall."

The decorations sold in everyone's points mall are the same, so even if you snatch the decorations bought by others from the mall, it is useless and can only be put in the parasitic tree house.

"Give it to him and put it in his tree house." Xu Xin nodded.

Since he has the special functional area of ​​[external weapon research room], he needs decoration to increase it. Although I don't know what the use of adding boost points to this research room is.

Increase research success rate?

It should be like this, Qi Xuefei also said that her drug research may fail.

Xu Xin came to the first floor.

Ke Ke had been waiting for him on the first floor, and when he saw him coming, she let out a "beep" and scratched the floor of the tree house.

Its current position is the center point of the tree house, which is the position of the trunk of the tree house.

This is to let Xu Xin chisel open the floor of the tree house so that it can go in and take out the core of the tree house.

but……

The first floor of this tree house is also seven or eight meters high. After taking out the core and causing the death of the tree house, how will they get out?

Collapsed with the treehouse?

Or, jump out of a window. But this height is not low...

It shouldn't be a big problem. Seven or eight meters is about the height of a three-story building. As long as you jump down and roll to buffer, you won't be hurt. With his current physical fitness, it is not too simple to roll and roll on the ground.

But the comatose guy on the second floor...

Xu Xin went back to the second floor and told Yin Wang and Mimi that when the tree house collapsed, remember to protect Ma Hongwei and don't let him die.

After hearing this, Mimi lifted the unconscious Ma Hongwei up with her paws, and put him on Yin Wang's back.

"Ah?" Yin Wang was stunned for a second, then shook his body, making Ma Hongwei lie on his stomach more upright so that he would not fall off easily.

Hmm... that's fine too.

Xu Xin returned to the first floor of the tree house.

"Are you going to get the core of the tree house?" Lou Fei'er had been waiting on the first floor, staring at Ke Ke. Seeing that Xu Xin was back, she was a little excited. She hadn't seen the scene of getting the core of the tree house.

To be honest, Xu Xin was a little bit looking forward to it.

Because this tree house is not the green-level tree house he obtained before, but a blue-level tree house!

A higher-level tree house, he has not obtained the core of the blue-level tree house yet!

I don't know what is the effect of the core of this blue-level tree house. Could it be that it can obtain higher-level materials than purple-level?

No, it shouldn't be, even if it is, Xu Xin and the others can't use it for the time being. After all, using higher-level materials than purple-level materials to make weapons and armor, etc., basic materials need purple-level materials. How can they have so many purple-level materials!

It's useless to guess, so let's dig it open and have a look.

Xu Xin took out his blue-level iron axe, and Ke Ke also jumped behind him.

He swung the ax in his hand and chopped it on the floor in the center of the tree house with a "click".

The floor immediately cracked, but the degree of cracking was much smaller than when Xu Xin dug the floor of the green-level tree house. Compared with the green-level tree house, the blue-level tree house is stronger in all aspects.

Xu Xin continued to cut down. It took him more than a dozen axes to cut the ground that could have been chopped up with only two axes, exposing the hollow in the tree trunk below.

The trunk of the blue-level tree house is also much thicker than the green-level tree house, and the hollow hole in the trunk is also much larger.

Xu Xin looked inside, and in the soil at the bottom, buried a pearl emitting a bright white light, half of which was exposed from the ground.

The bright white light is much brighter than the core of the green-level tree house.

This light is really similar to the light emitted by the giant energy core fragment in his hand...

Are the two really related?

But the tree house seed was given to him by the mysterious voice. According to his speculation, the mysterious voice should be the Bloodstripe family that now controls the world, that is, outsiders of this world, not the lineage of giant beasts.

What's the secret?

Forget it, don't want to.

I can't even think about it now.

"Coco, go down and get that core up."

"Oh!"

Ke Ke had been eager to try at the entrance of the cave for a long time. Hearing what Xu Xin said, he rushed in immediately.

"Hmm...? So that's how the core was obtained..." Lou Fei'er rolled her eyes slightly, wondering what she was thinking.

"After the core is taken out, the tree house will be destroyed immediately, remember to jump out so as not to be buried." Xu Xin warned.

"Yeah, I see." Lou Fei'er also looked down.

Coco has reached the bottom of the trunk by this time.

The core is seven or eight meters away from the first floor of the tree house, so before Ke Ke went down, Xu Xin hadn't noticed its size. When Ke Ke went down, he had a reference. He was surprised to find that the core of the blue-level tree house was actually bigger than Green-level treehouses have a much larger core.

The core of the green-level tree house is only the size of a fist, while the core of the blue-level tree house is a circle larger, and it feels like Coco's small mouth is about to be unable to hold it.

Ke Ke first patted the core of the tree with his small paws, and then pushed it twice, but the core did not move at all.

It used both hands and feet, and even used its mouth, but it failed to get the core out of the soil.

"Hey! Hey!" Ke Ke scratched at the core twice, and yelled angrily.

"Ke Ke, stop digging, you won't be able to bring it up if you dig it out, come up quickly." Xu Xin stopped Ke Ke.

"Hey..." Hearing this, Ke Ke's ears immediately collapsed, and her big tail drooped to the ground.

But it also knew that the orb was too big for it to pick up, so it couldn't help much, so it could only jump up from left to right, and then threw itself into Xu Xin's arms: "Hey..."

"Let me go down." Lou Fei'er volunteered, sat on the edge of the hollow tree hole, looked at the core below and said, "I can bring it up."

The hollow tree hole in the green-level tree house is wider than the width of a person’s shoulders, and people can enter it. The hollow tree hole in the trunk of the blue-level tree house is wider, almost as wide as a well. It is no problem for Lou Feier to jump down. Even easy movement is possible.

"Okay." Xu Xin touched Ke Ke's head, nodded and agreed.

He originally wanted to go down by himself, but since someone wanted to do it, he didn't have to do it himself: "Remember to get up immediately after getting the core, the tree house will collapse immediately."

"Understood!" Lou Fei'er gave a very non-standard salute, and then jumped down.

Her feet and back rubbed against the hollow, and she slid down, landing on the soil below.

"The core of the blue tree house, the core of my tree house, is this right?"

Lou Fei'er stretched out her hand and touched the core, and suddenly, a feeling of warmth flowed through her body.

Does this core still have this function?

In the parasitic tree house that Xu Xin gave her, there was always a tree house core inlaid in the center of the floor, where it was always filled with energy and constantly emitting a white light.

She has studied that core for a long time, but she has not researched anything.

Touching that core doesn't feel like it does now.

"What's wrong?" Seeing Lou Fei'er touching the core, Xu Xin started to be in a daze, and asked, "What's the matter?"

"Ah, I'll bring the core up right away!" Lou Fei'er came back to her senses, and quickly grabbed the core with her hands.

The result is the same as cocoa, which cannot be moved.

She showed that she dug the surrounding soil with her hands, took out a dagger, inserted it under the core, and then pried it hard.

The core was immediately pried off.

"Come up!" Xu Xin could already feel the floor shaking slightly.

Through the window, he saw that the leaves of the banyan tree outside were rapidly turning yellow.

This blue tree house is about to collapse!

Lou Feier didn't talk nonsense, kicked her legs on both sides of the tree hole, jumped up quickly with her agile figure, and then handed the core of the tree house to Xu Xin: "Here."

Xu Xin didn't have time to read the introduction, so she put the core of the tree house, which couldn't be wrapped in one hand, into her backpack: "Let's go!"

Ke Ke was already standing by the window looking at them. Seeing Xu Xin approaching, she immediately jumped out of the window ahead of them.

Coco was very light, and landed very easily. After landing, he turned around and yelled at them, telling them to come down quickly.

Xu Xin also jumped out of the window immediately.

The moment he landed, he rolled over, removed most of the impact force, and landed perfectly.

Standing up, he patted the dust off his body.

Lou Fei'er also rolled beside him, and stood up deftly.

Mimi and Yin Wang were even more relaxed. Although they had such huge bodies, they landed easily after jumping out. Ah Fu didn't have to worry anymore, he flapped his wings and flew out slowly, looking back at the withering tree house in mid-air.

Ma Hongwei, who was unconscious on Yin Wang's back, was not so lucky. After the Silver King landed, he rolled off the wolf's back because of the bumps, and fell face-to-face on the ground.

... As long as he is not dead, give him a mutated pill, activate the mutated power, and heal even the most serious injuries.

The banyan leaves of the tree house in front of me have completely withered and fallen off, revealing the square tree house inside.

Dozens of heavy crossbows were also revealed on the outer wall of the tree house.

Only then did Xu Xin discover that half of the heavy crossbows hidden in the canopy of the tree house were new crossbows developed by Ma Hongwei.

The tree house made a sound like a broken branch, and then, cracks appeared on the wooden outer wall of the tree house, and the cracks became more and more dense, and the cracks became bigger and bigger.

And on those heavy crossbows, cracks appeared along with the tree house, and they became loose.

"boom!"

Under their watchful eyes, the entire three-story tree house collapsed, and together with all the heavy crossbows, it turned into ruins all over the place!

Only a single tree trunk remained standing in the middle of the ruins.

The collapse scene of the blue-level tree house is much more spectacular than the green-level tree house.

"It turned into ruins..." Lou Feier opened his eyes wide and looked at the scene in front of him, then turned to look at Ma Hongwei who was lying on the ground, "This guy, I'm afraid he will go crazy when he wakes up. , the home is gone."

Xu Xin walked into the ruins, flipped it a few times, and sighed after confirming that the heavy crossbows were also broken along with the tree house.

It's a pity that those are all blue-level new heavy crossbows.

Fortunately, he got a core of a blue-level tree house!

He took the core out of his backpack.

[The core of the small tree house: the core that provides the growth energy for the tree house, and the tree house dies immediately after being taken out. The energy in the core of the small tree house can upgrade blue-level materials to purple-level materials. When the energy is full, it can be upgraded three times in a row. The white light emitted by the core of the small tree house will cause the beast to feel fear and make it afraid to approach, and at the same time, it can dispel the heat and cold around the holder. 】

"oh?"

This core, something!

What Xu Xin obtained from the green-level tree house before was [the core of the low tree house]. The core of the low tree house can only upgrade a blue-level resource to purple-level, and this [small tree house] Core], full energy can be upgraded three times in a row.

Not bad, as he expected.

However, the ability introduced later made him feel very familiar.

To disperse the beasts and maintain the temperature?
