"There are more and more bugs floating up. ”

Han Xuening was slightly stunned, Qin Fengyi used a clip made of bamboo chips to collect silkworm cocoons, this child knew from the beginning that there were a large number of insects hidden inside, and after bringing it back to the shelter, the plastic bag was sealed and never opened at all.

"It's impossible, you've picked it all up, how can there be any bugs?" Lin Qingxue looked at the insects surging in the golden pot, these things were very disgusting.

"You have to know that there are many more creatures on the ground than there are in the trees, and the cocoons make a good habitat for these creatures. Qin Fengyi tried his best to get out the scalded insects, and a worm was broken into two pieces in the process of taking it out, and in the process of cooking at high temperatures, the body of the insect was basically broken.

"Suddenly I felt ...... The cocoons are not clean. Lin Qingxue was a little stunned, at first she thought that it was quite good for her aunt's towel to be filled with silkworm cocoon silk, but now these scalded silk threads are also mixed with the shells of many insects, you must know that this thing is padded there.

"After boiling at high temperature a few times, the sediment will be drained, and the shells of insects will be picked out as much as possible, even if there are insect legs in them, it doesn't matter, these things are all disinfected, and there is no effect on the human body. Qin Fengyi continued to stir the golden pot with a bamboo pole, trying to turn the cocoons into broken filaments.

"Qin Fengyi reminds me of the most common phenomenon in modern times. Han Xuening combed her loose hair with her hands, and her beautiful eyes raised to look at Qin Fengyi, "All the things we eat now have never been clean when they were processed from raw materials. ”

Indeed, an uncle next door to Qin Fengyi observed the flour processing of the flour mill, and after returning home, he asked his daughter-in-law to plant wheat and eat the grain he grew in the future, and he didn't eat the flour he sold.

Of course, there are many other foods like this, such as those various meatballs, ham sausages and other non-staple foods, but anyone who has seen processed them will have a shadow.

"Out of sight is pure...... I think that's the reason, most foods nowadays, after seeing the processing process, will feel nauseous. Lin Qingxue sat on the leaves, looking directly at the steaming golden pot with her eyes.

Ten minutes later, the first cooking of the cocoon is completed, the silk thread of the cocoon is fished out, placed on a bamboo basket, drained, and waiting for the next boiling water to boil, the first pot of water is as black as ink, which is full of sediment and insect limbs.

In this way, after boiling 3 times, the water was finally boiled, and the silkworm cocoon silk completely turned into silkworm cocoon velvet, which only needed to be dried, but Lin Qingxue was staring at filling the aunt's towel with silkworm cocoon silk.

"Do you think that the silkworm cocoon silk dried with fire like this is not easy to use?" Lin Qingxue was wringing out the cocoon silk and laying it flat on a bamboo board, and then it was 20 centimeters high from the flame, and dried like this.

"In my opinion, as long as it is dry cocoon silk, it is easy to use, and the texture of this thing should be similar to silk, and the soft star is very strong, but the water absorption is not as good as cotton. Qin Fengyi touched the silk cocoon, and these things were rubbed hard, and they could be kneaded into threads.

It seems that after that, we will have to start making a loom, and with a loom we can make silk, the only pity is that there are a little few cocoons, and we have to wait for those pupa to bite through the new cocoons and then increase the number of them.

"It's very annoying to make silk from cocoons, so I can try knitting sweaters. Han Xuening looked at the silkworm cocoon silk and had a headache, processing these most primitive materials often requires very advanced technology.

The loom is researched by the ancients, in modern times, few people will do it, modern people are manufacturers to buy high-tech looms, basically the kind that is fully automatic.

"I can try to make a loom...... Qin Fengyi looked at the parts of the loom, and it was not too difficult overall.

"You also make a loom?" Lin Qingxue was stunned, and then looked at Qin Fengyi's..."Your old grandfather is so powerful, he can do anything." ”

"What are you thinking, there is no old man!!" Qin Fengyi is going crazy, how can this Nizi be so simple, where is the old man, the old man doesn't live in Ding Ding, he is usually in the ring!

"What are you talking about, what old man?" Han Xuening was also mixing with the old man, frowning and looking at Qin Fengyi and Lin Qingxue, there were quite a lot of secrets between the two.

"Nothing...... I'll take a shower and I'll go to bed later!" Qin Fengyi stared at Lin Qingxue, tonight's aunt came suddenly, which caught him off guard.

In the bathroom, Qin Fengyi experienced the feeling of the city, although it was dark inside, but the temperature of the water was okay, about 33 degrees, and it was just right to take a bath.

The water heater made of float needs to be improved, in fact, you can make two floats, one for hot water, one for cold water to mix, two floats with a pipe, and the part of the pipe connection uses a valve to control the size of the water flow, so as to adjust the temperature.

After taking a bath, he was refreshed in the fresh water bath, and Qin Fengyi saw Lin Qingxue and Han Xuening discussing something from a distance.

"Teacher Han, what do you say is the treasure on this treasure map?" Lin Qingxue was holding a small piece of treasure map and was observing.

"I don't know, it could be gold, it could be gems or something. Han Xuening was holding half of the metal plate, this shape was the mark on the stone door of the secret room, but unfortunately it was only half, if he found the other half, he would probably be able to open the mysterious stone door.

"Then who buried the treasure?" Lin Qingxue looked at the intricate lines and patterns on the map, and her mind was in a mess.

"I have a delusion...... Treasure maps don't seem to have been made by humans. Han Xuening groped for the lines on half of the metal plate, this texture was very rough, and the material of the metal plate was not known what it was made of.

Indeed, there are many doubts in the ancient city, the group of giant apes alone is incredible, the creatures that can drive and eat the giant apes must be very large, the height of the internal building of the house is about 8 meters, if it is a human building, there is no need to make it so high.

"Isn't it a human?" Lin Qingxue blinked, "Isn't it a human?"

"Probably......"

After Qin Fengyi took a bath, he also participated in the discussion of the treasure map, and the result of everyone's discussion was that he went to sleep!

Before going to bed, Han Xuening and Lin Qingxue poured the boiled shark oil into a plastic bottle, used leaves as a funnel, poured all the mild shark oil into it, and harvested about 300 ml of shark oil, which are important materials in the future, which can treat burns and wounds.
