Although they cannot be recycled, burning crossbow bolts only require wood and vine sap, which saves a lot of materials.

Gu Yan

Xu Xin immediately made forty rounds as a backup.

Continuing to flip through the pages, Xu Xin finally saw what he had been looking for.

Small Explosives: Small explosives that explode on impact. They are quite powerful and can be used to craft explosive arrows and crossbow bolts. 20 Small Explosives requires 1kg of Vine Sap, 2kg of Saltpeter, and 20 pieces of Charcoal.

Small explosives?

It seems to be different from what he imagined, but...

Small explosives can actually be used to make explosive crossbow arrows!

He did have saltpeter, as Li Wenxi had given him some green-grade saltpeter before, but he didn't have charcoal.

The furnace was right next to him, and Xu Xin immediately threw dozens of pieces of wood into it. Charcoal burned very quickly, after all, it was the primary material for making torches. In just two minutes, twenty pieces of charcoal were burned.

After preparing all the materials, Xu Xin immediately made a small explosive.

Twenty small explosives the size of firecrackers appeared on the weapons production table.

After the small explosives are crafted, the explosive arrows and explosive crossbow bolts are also unlocked in the crafting list.

[Explosive Crossbow Bolts: Simple and practical explosive crossbow bolts with weak penetration. They explode upon impact. They cannot be retrieved. Explosion is art! 20 explosive crossbow bolts require 4 wood, 2 feathers, and 20 small explosives.]

Immediately made, Xu Xin had 20 more explosive crossbow arrows in his hands.

Taking out his crossbow and carefully loading it with an explosive bolt, Xu Xin looked out the window, found a poplar tree that was relatively far away from the other trees, took aim, and pulled the trigger.

"Swoosh--" the crossbow arrow shot out. With the help of the advanced crossbow, the exploding arrow shot towards the tree at an incredibly fast speed like a bullet.

"boom!"

The moment the crossbow arrow hit the trunk of the tree, a flash of fire lit up, illuminating the surroundings. Accompanied by a loud explosion, the whole tree was blown in half, wood chips flew everywhere, and the broken edge of the poplar tree gradually burned after the explosion, and the burning tended to get more and more intense.

“Ying!” “Ah?” “Meow?!”

Coco, who was curled up on the sofa and about to fall asleep, and Silver King and Mimi, who were resting in the corner, were so scared that they jumped up.

The bat hanging under the tree house let out a shrill scream, flapped its wings and flew to the window, warning Xu Xin in the tree house that there was an emergency under the tree house.

"It's okay, it's me. Don't panic!" Xu Xin explained quickly.

Hearing Xu Xin's words, Silver King calmly crouched down in the corner. Mimi seemed to give Xu Xin a blank look before also crouching down. The bat stopped by the window, tilted its head, and after confirming that there was no danger, flew back to the tree house and hung there again.

Coco perked up, and seeing that Xu Xin seemed to be going out, she immediately climbed onto his shoulders.

Xu Xin brought Coco down from the tree house and came to the poplar tree that was blown down. He poured a bucket of water on it and put out the fire.

The poplar tree was not only broken but also shattered into pieces, with wood chips flying everywhere, some of which were sparks. Fortunately, Xu Xin had specially chosen a tree that was far away from other vegetation.

But he didn't dare to be careless. He looked around for sparks and poured a few buckets of water before he felt relieved.

This is really powerful, and the damage range is much stronger than ordinary crossbow arrows that can only penetrate and poisonous crossbow arrows that are basically useless nowadays.

"However, explosive arrows are just like incendiary arrows. Don't use them if you can. The explosion will also cause a fire."

Xu Xin was a little troubled. He had finally obtained two powerful weapons, but they were not convenient to use in the jungle.

He looked at his watch and it was already two o'clock in the middle of the night. The jungle at night was still eerily quiet even after he shot an explosive arrow.

Back in the tree house, Xu Xin habitually used saltpeter to cool down and then lay down on the bed.

I really experienced a lot on this day.

…

Xu Xin was awakened by the mysterious voice again.

[From today on, all survivors officially enter the second stage of survival. 】

[The following will introduce the content of the event, please listen carefully, survivors.]

The rainy season is over, the jungle is reborn, and the tree house is also nourished by rain and lightning.

[For all those who survived the rainy season, your tree houses will grow and evolve again over a period of one day and one night.]

[I'm sure you've all noticed that the tree house's protective capabilities are weakening.]

This event is: Treehouse Defense. As the treehouse grows, its protective abilities weaken and it becomes more fragile than before. This time, it's up to the survivors to protect their own treehouse!

[Your mission is to protect your tree house and survive in the next day and night! ]

[Friendly reminder: Even if the treehouse's protection ability is weakened, do not explore areas outside the treehouse's protection range, otherwise very scary things will happen.]

[The time for this reward activity is from 6:00 today to 6:00 tomorrow]

[After this mission, the tree house will have new upgrades and features.]

【The battle to defend the tree house begins now! 】

Listening to the content of the event, Xu Xin instantly came to his senses.

Treehouse Defense?!

This event actually started at six o'clock, without even any advance warning!
