Some of them are metallic, some are completely transparent, some are dull brown, and some are very bright bright yellow sky blue.

"What is this?" Qin Xu asked suspiciously. When the alienated termite ant nest was in the first two forms, this situation did not appear, so Qin Xu was a little confused.

Old Master Qin glanced at it and said indifferently: "Some substances that alienated termites don't need very much, on the basis of satisfying its own reproduction and growth, they will dispose of it and expel it from the nest. ”

In Master Qin's opinion, these substances excluded by alienated termites are no different from the things in the garbage heap outside, and he doesn't care.

"In the first two stages, the alienated termites used their main energy for reproduction and nest construction, so there was no excess material discharged, and after this nest change, the alienated termites had the ability to screen the food they ingested. ”

Qin Xu squatted down, picked up a silver-white metallic bead on the ground, looked at it seriously, and flicked it lightly with his fingers.

"It looks a little familiar," Qin Xu scratched his head and muttered to himself, "It's a bit like the aluminum pot that my mother used to boil the bath water before." ”

Decades ago, the supply of steel in China was insufficient, and many pots and pans on the market were made of aluminum.

Later, after the iron pot was replaced at home, Liu Amei heard rumors that the frequent use of aluminum products would lead to Alzheimer's disease, so she naturally did not use the aluminum pot to cook food, but she felt that it was a pity to discard it, so she simply used it to boil hot water.

However, with the popularity of water heaters, the large aluminum pot was left idle.

Occasionally, chickens and ducks are slaughtered at home, and boiling water is plucked, and the big aluminum pot will be moved out to eat.

Qin Xu checked the weight of the silver-white metal ball in his hand, and it really felt like the texture of the aluminum pot, but the color was whiter and brighter.

Although Master Qin had not read the periodic table in chemistry class, he still knew the metals that were commonly seen in daily life.

He nodded and confirmed: "I didn't see the aluminum pot you said, but this substance is indeed very common on the streets, and some of the bicycles, cars, and shop signs you use every day are useful for this kind of thing." ”

After all, Old Master Qin was from the cultivation world, and he didn't understand that for many people, the ability to alienate termites was the most precious and valuable.

Qin Xu picked up all the metallic round beads on the ground and asked Old Master Qin one by one if he knew their composition.

The beads are almost identical in size and shape, but they are light and heavy, and their weights vary greatly. Even if it's the same metallic color, there are differences.

Qin Xu used his common sense, with the help of Old Master Qin, to judge the steel beads, pig iron beads, aluminum beads, and copper beads.

This is the most common metal element in daily life.

Qin Xu knew that when they picked up garbage in Bac Ninh, they all had a simple classification of garbage. He decided to wait and ask them if they had been fed the metalwork.

In addition to the beads of different metals, the number of beads that are transparent on the ground is the largest.

Qin Xu picked up two, held them in his hand and observed, and found that the transparent round beads were slightly elastic, and they felt like natural rubber, colorless and odorless, similar in weight to aluminum beads.

With his own experience, Qin Xu couldn't be prepared to judge what its raw materials were, so he turned to continue consulting Old Master Qin.

Old Master Qin casually pointed to the panda that was happily gnawing on the plastic bag, and said: "That's it, the worker ants of the alienated termites gnaw these things, decompose them with their special digestive juices, and become the raw materials for building ant nests. Now that food is abundant, they are more selective about their ingredients and get some of the impurities they don't need out of their nests. ”

Therefore, Qin Xu feels that the fluff on the outer skin of the alienated ant nest of the national treasure version feels better than the predecessor of cats and dogs, which is not entirely an illusion.

Transparent beads made of plastic products processed from alienated termite digest?

Although it was called an impurity by Old Master Qin, Qin Xu felt that the raw material of this transparent bead would have a greater surprise, and it was not useless garbage as Master Qin said.

Metallic and transparent balls are the most abundant on the ground. The other colors are one or two grains, and Master Qin studied it, and only said that it was something that the alienated termites tossed out by themselves, with plant ingredients and mineral components, which were more complex than metal balls and transparent balls.

Anyway, no matter what color they were, they were really useless in the eyes of Old Master Qin.

Pick up all the round beads, Qin Xu didn't have a bag, he just pocketed it with his coat, and then left this room.

When Qin Xu walked out, the plush round guy lying on the ground raised his head slightly, waved his short hairy tail, and said goodbye to Qin Xu lazily.

Qin Xu couldn't help but smile when he saw that it was rare to stop eating, and said, "Okay, you just stay here, and I'll see you next time." ”

Close the door and lock it, as soon as Qin Xu went out, he ran into Kong Wang and Lu Xiaoping, who had just woken up.

"Uncle Liu!" Kong Wang felt very ashamed, it was rare for Uncle Liu to come over, and he was still asleep on the bed.

In fact, they wake up not late at all.

Six o'clock in the morning, for most people, is still the time to immerse themselves in dreams.

"Uncle Liu, what's in your pocket?" Lu Xiaoping was washing rice in front of the kitchen, and asked curiously when he saw Qin Xu's round beads in his pocket.

Compared with the two Lan You Beining, who knew how to restrain and disguise, Lu Xiaoping, who was still a teenager, spoke more directly.

"Some round beads. Qin Xu didn't know how to describe the "garbage" discarded by these alienated termites, so he had to say vaguely.

"Are there any plastic bags here?" Qin Xu said and immediately asked.

Kong Wang, who was beating eggs, nodded repeatedly, turned around and took out a used clean plastic bag from the kitchen, and handed it to Qin Xu.

"This is the original greens, I washed it, is it okay?"

"No problem. Qin Xu put the beads into the plastic bag in one fell swoop.

"Uncle Liu, have you had breakfast, we are going to cook some porridge, can you stay and eat together?" Kong Wang worked in a small restaurant, so he is now in charge of three meals a day for four people.

Qin Xu's salary for Lanyou and Beining is slightly higher than the average.

Maybe this salary can't support them to buy a house in Chaohai City, but it is more than enough to ensure that three meals a day with meat, eggs and meals are balanced and nutritious.

Therefore, since they came to work here for Qin Xu, the meals for the four of them have been much richer than before.

Qin Xu didn't sleep all night, ran from the city to the old cemetery in the deep forest, then ran to find Pang Shufeng, and finally ran here again, running around, indeed a little hungry.

However, he didn't have time to wait for Kong Wang to cook the meal, he shook his head and said, "I still have something to do, I'm about to leave, you don't have to cook more of my food, eat it yourself, and try your craft next time you have time." ”

Kong Wang was inevitably a little disappointed. He has been working in the kitchen for the past two days, and he really wants to show it in front of Uncle Liu.

Qin Xu turned around and walked out a few steps, then turned his head to Kong Wang and Lu Xiaoping and said, "I will not be able to hire you before you are adults, but I will put an extra 1,500 yuan into your account in Beining every month to give you pocket money." ”

When Kong Wang and Lu Xiaoping first heard Uncle Liu say the first sentence, their faces drooped, but when he spoke, they couldn't help but cheer loudly.

"Also, I will help you connect with nearby schools later, in any case, you must complete the basic study and examination of the nine years of compulsory education, if you are willing to go to high school and university, I will also lend you money in advance, and when you are able, I will repay it. ”

Liu Jinghuai has a lot of funds in his bank account, and Qin Xu draws some money to do some good deeds that are close in front of him, which is just a fraction of the deposit in it.

Kong Wang and Lu Xiaoping's excited expressions suddenly froze, and they wanted to cry without tears and looked at Uncle Liu, who was chubby and smiling lovingly.
