Starting Off Survival With A Small Treehouse Chapter 39

"This is...?" Xu Xin picked up the bottle of gray potion.

【Special tree house root medicine (purple): pouring it under the tree house can promote the development of the tree house roots, and each medicine can expand the protection range of the tree house by three kilometers. 】

A purple-grade potion! Or a potion that expands the protection of the tree house!

Xu Xin's tree house's protection range is now three kilometers in radius. After using this potion, it will expand to six kilometers in radius! This is not only doubled, the protection radius has doubled, and the area has been quadrupled!

In other words, Xu Xin, who has used this potion for her tree house, will have four times the range she can explore! In this expanded scope, there may be another resource area.

Good things, really good things, worthy of being a treasure chest.

Xu Xin picked up the thin card again.

[Metal Products Automatic Unlock Contract (Purple): Recipe that unlocks all metal products. After using this contract, all metal-related crafting recipes can be automatically unlocked after obtaining all kinds of raw materials. 】

After the tree house renovation contract, he has obtained another contract, a contract related to the formula of metal products!

With this contract, Xu Xin is finally no longer limited to making stone tools!

[Congratulations, you have opened three kinds of treasure chests, gold, silver and bronze, and become the first person in this batch of survivors to find all three kinds of treasure chests and open them all. The rewards will be distributed after the jungle exploration event ends. 】

[Survivors please make persistent efforts, strengthen themselves, and strive to survive in this world. 】

The mysterious voice sounded again.

He was the first to get all the treasure chests.

The event is not over yet, and I don't know if anyone else will find the treasure chest.

To be honest, if it wasn't for Coco who said there was a treasure chest underneath, he would have to pull him down. With his cautious personality, it would be impossible to drill into this hole and dig an underground passage.

The conditions for obtaining this treasure chest are too harsh.

Xu Xin shook her head, without thinking about it, she looked at the contract in her hand and chose to use it.

Like last time, the card representing the contract shattered in his hand and merged into Xu Xin's body. Xu Xin felt a force pouring into all parts of her body.

This time, he not only felt stronger, but even his mind became clearer. Everything he had just experienced was quickly sorted out in his mind.

First of all, that huge piranha flower should be the monster guarding the entrance to this underground world.

This abrupt iron room underground, like the people in the room, has been buried underground for many years, but the incomparably foul-smelling red mist in the room does not know where it came from.

The person in the room is not from this world, but he came here with the tools and food of his original world, which shows that the way he came to this world is different from those of the survivors like Xu Xin, but how did he come? Xu Xin can't understand now.

The treasure chest of this quest is bound to the secret of the underground space. The treasure chest should have been placed in this location on purpose. Anyone who finds the treasure chest will definitely see the underground world before finding the treasure chest. secret.

And those who can't find the location of the treasure chest can't find the secret either.

Who is that mysterious voice? What brought them into this world? Could it be that after they grow up, they will fight against those monsters deep in the ground?

How did those monsters come about? The size gap between them and the creatures on the surface is too great.

He thought of the giant boa at the heart of the lake and the giant crocodile at the bottom of the stream. These two unreasonable giant creatures must have come out of the ground, and the connection below the lake is likely to be a kilometer deep underground.

And there is this potion in the treasure chest.

Xu Xin looked at the bottle of grey medicine in his hand. The whole bottle was only about 300ml, and the weight was about the same as the filled beverage.

The role of the drug is to promote the development of the roots of the tree house and expand the protection scope of the tree house. Does this mean that the root of the tree house is what protects Xu Xin and the other survivors from underground creatures?

A picture appeared in Xu Xin's mind.

During the two hours that the tree house was growing, while the tree house on the ground was growing, the roots of the tree house also differentiated underground, extending in all directions, extending to three kilometers away.

The roots of the tree house are intricately covered underground, blocking monsters that want to come out of the ground. Once a monster appears, it will be sucked by the roots of the tree house and quickly turn into dry and crisp specimens.

Therefore, when the roots of the tree house grow longer, the protection range of the tree house becomes correspondingly larger.

Xu Xin felt that this explanation made sense.

This also explains the reason why the mysterious voice emphasized over and over again that the small tree house must not be abandoned, because the tree house is the most powerful weapon and the greatest guarantee against underground monsters.

After thinking about all this, Xu Xin's mood relaxed a little. According to what the mysterious voice said before, the monsters underground will not attack them at least in the near future, they only need to concentrate on dealing with the beasts on the ground.

The tree house will protect them.

Xu Xin put the treasure chest into her backpack. Although the treasure chest is made of gold, it is very heavy, but Xu Xin's strength is no longer the same after several times of increase. With the backpack that reduces the weight to 20%, this treasure chest has nothing on his back. question.

He was actually looking forward to what would happen after assembling the three treasure chests and piecing the pattern together.

Before leaving, he decided to take another look at the underground world. After all, after he went out this time, he probably wouldn't come back here for a long time.

But Coco didn't walk to the edge of the cliff like he did, but lay on the back, a little scared away from the cliff.

It's still the same scene of a group of demons dancing wildly.

Huge monsters covered in seaweed, giant piranhas several times larger than the piranhas on the ground, blood-red vines everywhere, and firefly-like creatures the size of carts, and some others that are completely on land. Impossible giant plants and animals.

These are all things he will face in the future.

He has to improve himself quickly, so that he has the ability to fight against these things!

Xu Xin looked forward and suddenly her eyes narrowed.

At the top of the entire underground world, he saw many downward protrusions.

Now Xu Xin's position is equivalent to the lights on the ceiling in the room, and those bumps are other lights.

"These bumps should be the treehouses of other survivors, or the roots of the treehouses." Xu Xin thought thoughtfully.

According to his inference, the inside of these protrusions should be the intricate roots of the tree house, which are used to protect these survivors from these underground creatures.

"Although I don't know who brought us here~www.mtlnovel.com~, he must be playing a big game."

Xu Xin took one last look at the underground world, then turned her head and walked back to the iron room.

The skeleton was still scattered on the ground, Xu Xin grabbed Coco, who wanted to play ball, and pressed it on his shoulder.

"Hey!" Coco cried out in dissatisfaction, but still lay on his shoulders obediently.

The next task seems simple but not easy.

Climb up!

Looking at this deep passage, Xu Xin felt that her legs were shaking.

He just climbed down before, which made his arm extremely sore. Now he has to climb up!

He even carried a treasure chest!

Tired him to death!

Xu Xin glanced at the little guy on his shoulder: "Can you crawl by yourself?"

"Hey!" Coco shook his head violently.

"You're lazy, you got it!"

"Hey!" Coco wanted to refute, the distance between each step was almost as long as its body, how could it climb!

With a sigh, Xu Xin decided to eat something before climbing. After all, he threw up all the food he ate last night. Although the contract just now made his body recover a lot, he stayed below for so long. I'm afraid it's already dawn above, and it's time to eat.

Just when he took out an apple and wanted to nibble, there was a sudden hissing sound of exhalation.

"what sound?"

Xu Xin turned her head back vigilantly.

In his terrified eyes, the half-opened iron door suddenly closed automatically, making a loud noise, and then a familiar red gas spewed out from the gap between the wall and the floor of the iron room, gradually spreading.

"Fuck!!!"
