Xu Xin was a little excited.

You must know that the core of the tree house can only upgrade basic materials. This kind of material cut from living creatures cannot be obtained through core upgrade. It can only be cut with a boning knife!

A piece of fish scale skin was curled up on the ground, emitting purple light.

There was only one portion, but Xu Xin was already very satisfied. He reached out and picked up the fish scale skin.

[Mutated piranha scale skin (purple): a type of animal skin, very tough and 100% waterproof, it is a very high-end material! 】

The tough skin of the piranha is also a kind of animal skin. Xu Xin has known this for a long time. He has already obtained more than a dozen blue-level fish skins.

Purple level animal skin...

Animal skin has two functions, one is used to make leather armor, and the other is used to make backpacks.

Xu Xin immediately decided to make this animal skin into a purple-level backpack.

He doesn't really need another set of purple-level armor. After all, the skin of the piranha is stronger than the scales of the giant anaconda in the middle of the lake. There is no need to choose.

But the purple-level backpack is different. Now he has to carry two blue-level backpacks with him all the time, and sometimes he even carries one for Silver King. It is really not enough, especially when encountering heavy things. The weight has been reduced to 10

% is meaningless and cannot be used.

He needs a better backpack!

Xu Xin immediately came to the synthesis table and clicked on backpack creation.

The basic success rate of a purple-level backpack is also 80%. With the crafting room and armchair (blue), the success rate can easily reach 100%.

There was a flash of white light, and the purple-level backpack appeared in his hands.

[Exquisite backpack (purple): A backpack with 50 grids. The number of materials that can be placed in each grid is determined by the type of materials. It can reduce the weight of materials to 2% of the original type]

Good guy, 2%!

One-fiftieth! In other words, the fifty piranhas on his back are only equivalent to the weight of one piranha!

The weight of a blue-level backpack is reduced to one-tenth, and replacing it with a purple-level backpack directly increases his weight to five times!

Moreover, there are more grids, so he no longer has to carry multiple backpacks when going out.

Really good!

Purple level backpack, perfect!

Xu Hui immediately transferred all the contents of his original backpack, including his crossbow, steel halberd, spare resources, etc., into the purple-level backpack and carried it on his back.

As for the blue-level backpack that has been with him for a long time, let him keep it in the tree house as a warehouse!

He put away the dozens of blue-level fish skins that he had decomposed, kept two of the fish meats for the next few days, and then put the rest into the ice cellar.

Although it's cold outside now, the fireplace is always burning in the tree house.

The temperature released by this fireplace can affect the entire tree house, keeping the temperature inside the tree house at around 25°C. Even the furthest level is around 20°C.

Therefore, it is still necessary to freeze the meat in an ice cellar.

After taking care of this, Xu Xin came to the alchemy room.

Now that he has the materials, he wants to make the other two coordinates.

All four tree houses will be connected tonight.

Li Wenxi even gave him some more materials, so the materials were very abundant.

Refining iron blocks into iron sand, refining black gold blocks into black gold dust, and then refining universal alchemy materials.

Soon, twenty-five sets of universal alchemy materials were completed.

Only twenty copies of the two coordinates are enough, but it doesn't hurt to make a few more. With his current success rate, he can already start making alchemy potions!

Xu Xin immediately clicked on coordinate creation.

With two loud noises, two coordinates were successfully produced, and two thick metal discs were stacked in the alchemy room. The success rate of the coordinates was still 88%. With the luck bonus of the koi, the possibility of failure

Very small.

Xu Xin initiated a transaction with Ji Chaoyang and Qi Xuefei on the spot, traded the two coordinates, and clicked on [Explorer] at the same time.

Brothers Qin Yunlong and Wen Guixin have almost cleaned up their surroundings.

With Wen Guixin at the top of their combat power, they pushed almost all the way, collecting what should be collected and killing what should be killed. They had already subdued three people, and there were five in the Parasitic Tree House. After all, there were some unsighted people in the outer area.

Everyone was killed by Wen Guixin.

The only drawback is that none of them have mounts, so their efficiency is much lower. After a day of focused work, they only managed to conquer three people.

Wang Lei and Zhao Xiaochuan did not meet with them and could only work on their own.

Xu Xin immediately spoke: "I have connected the coordinates with Li Wenxi and tried teleportation. It is completely feasible. I will be able to connect Ji Chaoyang and Qi Xuefei tonight. However, the other few of you are not able to do it yet and need to wait.

Wait."

Ji Chaoyang: "I have received it and selected the location. You can come directly to debug it."

Qi Xuefei: "Is this disk the coordinates? It's so different from the coordinates I imagined..."

Wang Lei: "Ah? Can the coordinates be traded? Isn't that just right?"

Xu Xin: "I need to activate it on site in person, so there is no use in trading it to you."

Wen Guixin: "Do you actually need to come in person? Then we won't be able to enjoy the convenience of teleportation for the time being. It's too difficult. The distance between Qin Yunlong and his tree house is still quite far."

Zhao Xiaochuan: "I seem to have seen the hills with the crooked-neck trees you mentioned!"

Wen Guixin: "See? Which direction of the hills are you in?"

Zhao Xiaochuan: "Western, right?"

Qin Yunlong: "My tree house is in the west of the hills! Can you see the three-story tree house nearby?"

Zhao Xiaochuan: "There is indeed a treehouse not far away, but it's so late at night that I can't see clearly. I don't know if it's on the third floor... Oh my god, there was an explosion over there in the treehouse!"

Qin Yunlong: "It was me who fired the explosive crossbow! Haha, we are indeed very close!"

Zhao Xiaochuan: "You went back to the tree house?! I'll go there right away. Hahaha, I finally found the organization, Oye!"

Wang Lei: "I'm tired of saying the word envy..."

Zhao Xiaochuan: "Don't panic, you should be not far from my location, maybe we can meet tomorrow!"

It seems that they are almost able to understand each other's positions, which will be much more convenient when he passes by in the future.

Although he still doesn't know how to get there, based on the number of people and distance, it's probably very far there.

Xu Xin: "I'll go out right away, first to Ji Chaoyang's place, and then to Sister Xue Fei's place. We will arrange the coordinates tonight to connect us with each other."

Ji Chaoyang: "Okay."

Qi Xuefei: "I understand."

Although it is already dark now, it is not late, it is not even seven o'clock in the evening.

Xu Xin took Yinwang and Coco, who insisted on following, and immediately went out to Ji Chaoyang's tree house.

The bare jungle at night makes the surroundings look even more desolate than the sunny day.

On such a cold night, there was no sound of birds or insects in the entire jungle, and it was unusually quiet.

Along the way, I could only hear the sound of King Silver stepping on the dead leaves and the whistling of the wind in my ears.

Xu Xin did not take out the energy core fragments.

Holding that thing at night is like a living target with a light source. Although the beasts in the jungle have not returned yet, he feels that it is not good to light up the surroundings like a light bulb.

I always feel like something is attracted to him.

Neither he nor Silver King needed lighting or warmth, so they didn't take it out for the time being.

"Hey..." Keli was lying in Xu Xin's arms, looking up at the sky, and letting out a soft cry from time to time.

It has been looking up all the way.

Xu Xin also looked up.

"Hey... it's Shuo Yue again?"

Tonight is another moonless night.

Xu Xin's brows frowned slightly.

Moonless night...

Those two moonless nights before were not peaceful nights.

The first moonless night was the night of the jungle exploration activity. When night fell, he encountered the monster guarding the gold treasure chest, the giant piranha flower that suddenly emerged from the ground.

The second moonless night was the day when red mist filled the entire hilly resource area. On that day, the surroundings of the hilly resource area became a dangerous area, and the mysterious passage under the altar was also opened.

Xu Xin looked in the direction of the hilly resource area. Fortunately, nothing unusual happened this time.

...it's better to be careful.

"Keke, is there something in the sky?" Seeing that Keke was still looking up at the sky blankly, Xu Xin asked softly.
To be continued...
