After some careful searching, Shen Nong barely finished checking this pile of insect corpses, the summer was scorching, even if he stood in the forest with little sunlight, he was still sweating from the heat.

"There are so few things that can be used. Shen Nong couldn't help but wipe the sweat from his forehead and said.

It turned out that not all insects had noteworthy materials in their bodies, at least after Shen Nong's painstaking search, after the insect intestines, he only found three valuable usable materials.

The first is the cockroach-like insect limbs and legs, Shen Nong found that this insect has very sharp hard spines on the limbs and legs, these hard thorns are dense, each with the length of Shen Nong's thumb, which can be used as a substitute for nails.

The second is the white heart in the body of a giant insect, which is the size of a car, and there is a natural crack on the side, which is hollow inside, and there is a certain space that people can climb into.

Shen Nong saw that the surface of this heart was smooth and the whole was light, and if it was placed on the water, it should be able to float, like a small boat floating on the water, so he decided to move it back to the Huangqiu tribe, maybe it could be of some use in the future.

In the pile of insect corpses, Shen Nong found a total of three corpses of this giant insect, that is, three white hearts, all of which were moved back by the tribesmen of the Huangqiu tribe.

The third available material was the most interesting and made Shen Nong feel very important, this material was found from a worm that had died so badly that he couldn't see it at all, it was a light-emitting organ that somewhat resembled the head of a deep-sea anglerfish.

I saw that the shape of this organ was a long stick, and on the end of the long stick grew a gray and transparent round sarcoma, and you could see that there was a yellow-brown paste-like object in this sarcoma, which shook slightly inside the sarcoma, and at the same time emitted a faint yellow light to the outside.

This is the most amazing thing about this material, and it is also what makes Shen Nong feel interesting, because it can actually illuminate!

Picking up this insect organ is a hard stone texture, and people can't help but feel that what they are holding in their hands is not the organ of the insect, but a stone spear.

The yellow-brown paste in the sarcoma can emit a visible yellow light in the daytime, and you can imagine how dazzling it must be in the dark night, and it is completely like a flashlight.

Shen Nong originally thought that if a large number of such materials could be found, then the lighting of the Huangqiu tribe in the future would no longer have to rely entirely on torches, and it could even be plugged around in the Huangqiu tribe to play the effect of a street lamp.

But it's a pity that Shen Nong only found such a worm organ in the end, which can be said to be quite rare, because of the uniqueness of this material, Shen Nong also deliberately gave it a resounding name.

Bachelor.

Since he really couldn't bear the sweltering heat in the forest, Shen Nong took the stick and walked to the wall, planning to rest first, anyway, this pile of insect corpses had been searched by him, and it should be impossible to hide anything valuable.

Green flakes and white insect eggs, as well as the other two materials, Shen Nong had already asked all the people of the Huangqiu tribe to move back to the tribe before, but Shen Nong didn't need to worry about it.

"Wu, drink water. ”

The moment Shen Nong climbed down from the wall, Peck Bone ran over with a clay pot and said very attentively.

The shape of this clay pot is very ugly, the twisted arc and weird shape make it impossible to call it a pot, but Shen Nong doesn't care, anyway, this kind of container is made to hold things, as long as it doesn't leak, then it is a qualified container, as for the beauty and good-looking...... Who cares about this in primitive times.

Looking at the clay pot full of water, Shen Nong couldn't help but ask curiously, "When you went to the ditch to get water, those mosquitoes didn't bite you?"

"I don't know, since it rained before, there are no bugs in our tribe. Bone pecking said.

Shen Nong immediately looked at the location of the ditch, really, now there are not even mosquitoes above the ditch, not to mention the mosquito swarm, it is very clean.

"It's a good opportunity to prevent mosquito swarms from breeding here. Shen Nong hurriedly took the clay pot in the's hand and said, "Peck the bone, you hurry up and find a few clansmen to move the stones we brought back from the Mud Eel Tribe, surround me in a circle next to the ditch, and then take a wooden board to cover it." ”

The life of a mosquito insect will go through four stages of egg-child-pupa - adult, and the female mosquito will discharge her eggs in the water, and then let them hatch and become a child.

The reason why there are so many mosquito swarms in the Huangqiu tribe is because there is a water source in the Huangqiu tribe, and this water source is exposed to the ground in the open air without shelter, which naturally attracts the attention of mosquito swarms and then comes here to breed.

It is important to know that a mosquito grows very fast, they can hatch from the eggs in 2-5 days, and then spend 10-14 days molting into a pupal swimming in the water, and finally fully mature the next day.

Shen Nong didn't know how many eggs, how many children, and how many chrysalis were floating in the ditch, so for the health and safety of everyone's body, he had specially explained before that everyone had to drink boiled boiled water from the bone pot, which was more hygienic.

Hearing Shen Nong's words, the pecking bone immediately agreed, turned around and ran to find a helper.

Shen Nong drank the warm boiled water in the clay pot as he walked towards the big cave, where all the materials he found in the pile of insect corpses had been stored in the cave.

As soon as he walked into the big cave, Shen Nong saw the piles of green flakes, so many green flakes were stacked together, and Shen Nong could directly and clearly see that there was a white gas rising above the flake pile.

Strode towards the pile of green flakes, the closer he was, the more Shen Nong felt a cold air hitting him, and suddenly Shen Nong's body couldn't help but tremble, and the whole person was directly refreshed in an instant.

"Comfortable!" Shen Nong couldn't help but shout happily.

This feeling is the most familiar to him as a modern person, whenever he comes back from a summer outing, and walks into the air-conditioned room after returning home, Shen Nong experiences this feeling, exactly the same.

"When the green flakes of this pile of feelings are put together, it is a 20-degree air conditioner!" Shen Nong said in surprise, it seems that from today onwards, he will no longer feel hot in this dry season.

Shen Nong picked up a green sheet and carefully attached it to the skin on his chest.

"Uh~~~Cool~~~~"
