When it was separated from civilization, all tools and materials had to be obtained from nature by all means, and now everything in human beings is taken from nature, and clothing, food, shelter, transportation, and daily necessities are completely inseparable from natural supplies.

"Rubbing the rope?" Han Xuening just joined yesterday, and I don't know how to rub the rope, but Lin Qingxue will.

Rubbing the rope is very simple, first cut the tree, then peel the bark, try to tear the bark slender and slender, and then the two strands are woven together, and the effect is better when soaking in water.

The two girls squatted on the ground full of mosquitoes, rubbing ropes while driving away mosquitoes with their little hands.

"Ah~~!these hateful mosquitoes!" Han Xue Ning was about to collapse, she changed clothes with Lin Qingxue, she was wearing a girl's skirt, and her legs and arms were full of big bags that had been bitten.

"Hurry up and find a way to repel mosquitoes, I really can't stand it!" Lin Qingxue has not fully recovered because of her foot injury, Teacher Han took the initiative to wear clothes with her patients, although the girl is wearing jeans and a white shirt, but the mouthparts of mosquitoes can still penetrate the clothes.

"Bear with me, make a boat and get out of here." "Qin Fengyi is skillfully making reed rafts, and it is said that someone has used reeds to make boats a long time ago, and they have sailed on the sea.

Qin Fengyi's survival system has a sub-profession of carpenter building, and there are many ships in it, including reed rafts, and more complex ones are reeds to build big ships, but the current carpenter building is primary, and the production process of reed ships cannot be obtained.

Lin Qingxue and Han Xuening quickly cut the bark with a meat knife, and then rolled it into a rope, while the stripped white sticks served as the general framework of the raft.

The triangle has a high stability, and the small shed in the shelter is built according to the triangle, and the small raft made into a triangle can not only reasonably accommodate more people, but also has a strong stability, and it is not easy to capsize.

The reeds were skillfully tied, the hull was filled, and a very solid reed raft was completed in ten minutes.

[Host crafts a sturdy reed raft with +45 proficiency...... The Carpenter building has been upgraded to the intermediate level, and the intermediate carpenter building blueprint has been opened. 】

Promoted to the Middle Pole Carpenter Building?

I'm rubbing, this carpenter's proficiency in building is better than expected, and he just made some traps and boats, and he was promoted to the intermediate level.

The mid-level carpenter building has a lot more things, such as an attack-type ballista, a wooden wall with super defense, and a loom that is essential for life......

Oh my God, if I build a ballista...... No, it should be said that a lot of ballistas were built, even if they encountered the demolition team, they were not afraid, and they could just start it!

Ballista requires something full of elasticity, such as springs and rubber bands, but unfortunately there is no such thing on an isolated desert island, but it can be replaced by the tendons of beasts, although the elasticity and contraction are lacking, but the lethality should not be underestimated.

"Wow, this boat looks very sharp!" Lin Qingxue sat on the reed raft, feeling very strong and reliable, Xiao Nizi patted Qin Fengyi's shoulder, "Not bad, young man, you are very talented!"

"Heh, give me a chance to show my talents, and I'll let you know the pain of moving!" Qin Fengyi grinned, looking at this posture, he knew that this cargo was driving.

Lin Qingxue could roughly guess the little secret, and immediately blushed and said angrily, "Shameless old driver!"

"What's wrong with Maidong?" Han Xuening looked at Lin Qingxue suspiciously, why did Xiao Nizi blush as soon as she said it?

"Nothing ......"

The raft has been completed, Qin Fengyi and others slowly pushed the raft into the water, the stability of the triangle made the raft float on the water surface in a balanced manner, several people were a wolf, and Yayale put on a rope to pull the boat in the water.

On one of the main streams of the swamp, a raft moves slowly, the swamp river flows gently, covered with a layer of duckweed, and on the bank not far away there are a few crocodiles, all of them are toothless and grown, and they are leisurely basking in the sun at the moment.

The raft was made very small, just enough to accommodate three people, Qin Fengyi sat at the front, always vigilant, in case there was a crocodile raid, and the two girls sat in the back row with Wangcai, the gray wolf looked at Lin Qingxue and Han Xuening with a curious expression.

The owner of the livestock is so blessed to have two opposite-sex partners, and the wolf is still a lonely wolf, so I want to have a lovely she-wolf to accompany him.

"Woo woo ......" Wangcai is being ravaged by Lin Qingxue, Xiao Nizi's ability to accept it is indeed very strong, knowing that it is a wolf and rubbing its head vigorously.

"Look at that ancient city!" Han Xuening pointed to the ancient city on one side, there is a section of the road without a wall, but you can clearly see that inside, the group of giant apes who have been demolished are still demolishing the house in an orderly manner, and the buildings that have not yet been demolished have a strange shape, at least 20 meters high.

I have to say that the giant ape's sensing ability is quite strong, and they saw a few people drifting on the water from a long distance, and several extreme giant apes were rushing over, standing on the shore and roaring.

"This ancient city is basically occupied by giant apes, there is nothing to explore, the only thing that has the meaning of exploration is the stone door in the tomb!" Qin Fengyi got the inheritance of the ancient druids in the hall outside the stone gate, there may be something behind the stone gate, but the stone door is locked, and a key is needed to open it.

"If we want to go there again, it means that we will have to be chased by the giant apes of the demolition team again...... Lin Qingxue said that it is too painful to be chased by those guys.

"Actually, if the swamp is smooth, we can come here by water in the future!" Qin Fengyi wanted to find the source of the swamp, according to the terrain, the source of the swamp should be on the mountain behind him, as long as he walked back around the ancient city, he could find it.

"There are really a lot of crocodiles here!" Han Xuening looked at the crocodiles around her with some fear, the further she went, the more crocodiles appeared on the swamp shore, and they seemed to be very curious about the fact that this raft floating on the water was diving into the water from the shore.

"It's basically saltwater crocodiles......" Qin Fengyi frowned, "Saltwater crocodiles don't usually attack ships, because these guys can't jump, and in my impression, it seems that only caimans can jump from the water." ”

Yes, saltwater crocodiles really can't jump, they are curious about rafts, but are quickly scared away by toothy music!

The big crocodile gave a warning signal and shook its body hard, and the water around it was splashed up, and the crocodiles around it who were about to approach received the signal and moved away.

"Look at that, that!!" Lin Qingxue pointed to the swampy land.
