It's so tightly hidden, it's no wonder you can't see it if you don't crouch down, or if you see it, you just think it's a firefly.

Zuo An'an looked at it for a long time, his eyes became brighter and brighter, and he suppressed his excitement, and asked Ah Quan to stand a little behind and take out the dagger from his body.

After fighting again and again, this dagger has worn out badly, and there are collapses one by one, and it is time to retire.

Zuo An'an stretched out the dagger.

The beetle shrank in the corner, its head and six legs curled up tightly, eager to shrink into its stomach, but Zuo An'an stretched out the dagger, it shook slightly, turned its head, turned a pair of mung bean-like eyes on its head, timidly and quietly, stretched out its head, as if sniffing, clicked and bit off a part of the dagger's blade, and then quickly retracted, as if it was not the guy who made the dagger out of a gap.

"Oh my God!" Zuo Anan exclaimed.

Ah Quan tilted his head slightly, he could hear Zuo An'an's voice was not shock, but surprise.

She knew what this bug was.

Then I saw Zuo An'an wrapping his hand with a handkerchief and reaching into his hand, he frowned slightly, the insect could even bite off the knife, her hand ......

The next moment, it was Zuo An'an who successfully caught the strange insect the size of an egg.

"Gold Eater! I'm not so lucky! Zuo An'an squinted with a rare smile.

Ah Quan asked, "What is a gold devouring worm?" ”

"A gold eater is a type of insect that devours metal, they feed on metal, the metal breaks down in their stomachs, and then the elements in it are repurposed to transform into a specific metal. Well, it's the thick shell on its body. ”

Ah Quan touched the shell on the back of the gold worm: "It's quite thick." "Even if it's metal. Nor is it any of the original known metals on Earth.

He saw that Zuo An'an was overjoyed as if he had received a treasure: "Can you use it?" ”

"Hmm." Zuo An'an picked up the gold-devouring worm with a handkerchief to make sure it wouldn't get out and run away. He held it in his hand and replied: "This kind of insect is like a snake or a crab in the sea, when it grows up, it will shed a thick shell to a certain extent, and that shell is the special metal they make, and it is an extremely rare material, whether it is to make weapons, or to make shields, protective clothing and other things, it is a first-class good material." ”

In the previous life, since the scavenger was reinvented again. With a meek, controllable new generation of scavengers, scientists have a deeper understanding of the genes that devour the bugs. They confirmed that the scavengers were only sensitive to organic matter and could not do anything about the others, so they diverged their thinking, is there a phagocytosis gene for other materials?

So devouring cement, steel, rock, rubber, all kinds of insects, fungi, endlessly.

Gold eaters are among the most advanced, first of all, they are genetically stable, once formed. They don't change for a lifetime, and secondly, they have a very docile personality, although they can bite even harder metal, but they don't know how to grow their teeth. But you can't talk about other things at all, so you don't have to worry about it betraying or hurting you if you keep it around.

The most important thing is, of course, its ability to produce unique and precious metals.

There are people in the market who specialize in selling gold-eating insects. Gold devouring insects are also divided into levels and talents, and Zuo Anan doesn't know much about this. Anyway, the more high-quality the gold-eating insects, the better the quality of the metal produced, and the high-quality and inferior gold-eating insects. In addition to their own genetic determination, it is also related to the metal they devour.

Generally, the gold-eating insects with excellent genes are wild, and there are not as many artificial as nature, there are always such and such defects, and the life span is not long.

But one of the most inferior gold devouring insects, that is not something ordinary people can afford, Zuo An'an only has those strong people, the sons and ladies of the base leader's family can afford to play this kind of thing, Tong Jiakun also has a good gold devouring insect in his previous life, and he spent almost all his belongings to get it, the treasure has to be the same as something, Zuo Anan has only seen it once or twice from afar.

As the name suggests, it can devour lime, that is, houses, cement, and then grow a thick layer of lime shell, this shell needs people to take the initiative to cut, cut it and add a certain solvent, they will dissolve, and then dry, into lime powder for any use. If you don't cut it, the lime worm will eat too much, grow too fast, be overwhelmed by the big stones on its body, and then die alive by itself.

The price of lime insects is much cheaper, and if you have your own laboratory, you can produce a large number of them a day, so generally the base will use the method of letting them die naturally, dissolving the whole insect body, and as long as you process one more step, you can get pure lime powder.

So starting in the second half of the third year of the end of the world, those ruins are no longer a problem, as long as you put in a batch of lime worms, wait a few days, the ruins will become worms that are only supported to death, recycle the worms, and then get new building materials, build a new city, think about it is wonderful.

Devouring insects are basically used in this way, waste utilization, by the way, to improve the quality of the material, generally speaking, only high-grade wild gold-eating insects will be carefully raised as pets, low-grade gold-eating insects are just recycling scrap iron treatment plants.

Ah Quan listened to Zuo An'an's words and was slightly puzzled: "How could it be there?" ”

Zuo An'an thought for a while: "Probably the genes in the pus spilled by those scavengers invaded this beetle and caused it to mutate." ”

Anyway, her luck is so good that it explodes, natural wild gold-eating insects, her usual weapon is a dagger, but she has been worried that there is no suitable dagger to use, with a gold-eating insect are still afraid of no materials? It's just one thing, before scientists have developed the relevant dissolving agents and forging methods, even if she gets the gold shell of the gold devouring insect, she will not be able to use it, and the gold shell is invulnerable.

It seems that scientific research or something, or can't relax, Zuo Anan decided that in order for himself to use the metal produced by this gold-eating insect as soon as possible, he also wants to promote the scientific research cause in W City.

But now it can't be used or hindered Zuo An'an's high spirits, and after going back, she studied the gold devouring insects for a long time, and finally Ah Quan shouted that she was hungry, so she reluctantly took a glass jar filled with canned fruit and put it up.

The little one is still very small, and it hasn't been peeled yet.

But she has one more thing to do in the future, find metal for it to eat, and it has to be good quality metal.

As for tonight, the gold-eater's dinner is the retired dagger.

The next day it cleared, and after the second rain, the wetland began to be fully constructed again. At the same time, Lu Zheng also returned. (To be continued......)
