"Where are we going?" Lu Shiqin looked at the grass around her and asked a little nervously.

This was just a hundred meters away from Changzhu Mountain, and Wu Sang said softly: "This time I want to go to the river to collect some clay, and at the same time, I will also bring back the horns we left on the river in the morning." ”

"Horns?" Lu Shiqin thought for a while, and quickly thought of the huge horn that almost pierced Zhang Xiangyang last time, "Use it to make a bow and arrow?" ”

Wu Sang hadn't thought about it yet, and said, "Bring it back first, it should be useful." ”

Zhang Xiangyang looked at the surrounding situation, after the rain, the grass and trees grew rapidly, and many animals began to come out to forage because of the heavy rain before.

Some of the birds fell directly into the surrounding grass, and even if Zhang Xiangyang and the others saw it, they couldn't catch it.

Most of the time you can see birds and mice, but you can't see even larger animals, such as rabbits.

There were no dangerous incidents along the way, and when the three of them came to the water's edge, they saw a herd of wild boars occupying the river's position.

These wild boars are all larger, most of them larger than the giant wolves before them, but slightly smaller than the buffalo.

There were more than a dozen of them, Zhang Xiangyang looked at them, and found no male wild boars, this group of wild boars were all wild boars without fangs, and he couldn't tell which one was the leader.

However, compared with the wild boars I saw on TV, the wild boars in front of me have become much larger in size, and two or three hundred catties are very common.

Led by a few large wild boars of more than 300 catties and a group of smaller wild boars, the wild boar that Zhang Xiangyang saw before was probably bigger than these small wild boars, and it didn't feel like it was inside at this time.

"Don't come closer, let's get the horns and leave!" Wu Sang didn't want to take risks, the animals in this world were extremely aggressive, and when there was enough food, she still chose to coexist peacefully.

Zhang Xiangyang nodded, so far, the gentle animal they have encountered is the wild boar, and the rest are aggressive animals.

And these big wild boars with cubs, as long as they have brains, know the danger.

What's more, the three of them are worried that these wild boars will attract ape monsters!

Quickly walked to the place where the horns had been discarded, and the three of them looked at the ditch after putting away the horns that the beast didn't want.

The water in the ditch had receded, and in just one morning, the water in it had bottomed out, and there was a big fish moving in the muddy water.

Wu Sang looked around, and after making sure that there was no danger approaching around, he quickly jumped down and began to touch the fish.

The strength of this fish was very strong, and although it was only more than half a meter in size, it still made Wu Sang waste a lot of strength to fish it out of the mud pit.

"It's a black fish, this fish has a very tenacious vitality, keep it for the time being, and eat it in a few days."

After Wu Sang put the black fish in the back basket and covered it, the big black fish was still constantly bumping inside, looking very energetic.

Zhang Xiangyang didn't dare to delay, and after taking a look at the big wild boar over there, he quickly left here with the two of them.

There is a lot of clay here, and when Lu Shiqin was on the way, he found a hillside with low grass.

"It should be here, yes!"

Under the puzzled eyes of Wu Sang and Zhang Xiangyang, Lu Shiqin quickly dug the soil on the ground with the bamboo in her hand.

When the soil and grass are lifted, the white clods hidden underneath are revealed!

Lu Shiqin squatted down, picked up a white clod of soil from below, and said to Zhang Xiangyang: "This is kaolin, which is a non-metallic mineral, and is the name of the soil rich in kaolinite, also called Guanyin soil, a very common thing, you can eat it, but if you eat too much, you will die of bloating and indigestion." ”

Zhang Xiangyang had previously learned the difference between pottery and porcelain with Wu Sang, and knew that if he wanted to make porcelain, he had to have kaolin.

I am relatively unfamiliar with kaolin, but I often see it in some books about Guanyin soil.

If it weren't for Lu Shiqin, Zhang Xiangyang would not have been able to dig in this kind of place at all, let alone realize that there is kaolin under this grassland.

The three of them played with two baskets of kaolin, and on the way back, Zhang Xiangyang asked: "Shiqin, you said that this kind of soil can be eaten in small amounts?" ”

Lu Shiqin explained: "If there is flour, we can use a small amount of kaolin to make a long shelf life, but the main raw materials are flour and some digestive aids, preferably sesame oil, animal oil can also be used." ”

Wu Sang said: "In this case, the matter of food storage will be easy to handle, I remember that there should be plants nearby that can be ground into flour, and we will collect more in the next few days, and animal oil will be available at home, which is not a problem." ”

Everyone hadn't thought about this problem before, because of time and because they were very unfamiliar with kaolin, even if they knew, they were only used as raw materials for porcelain, and they didn't realize that this thing was Guanyin soil.

The three of them returned to Changzhu Mountain safely, perhaps because they felt that it was still very early, and after sending their things up, they went to the nearby area to collect some fuel.

Some of the small trees destroyed by the storm were hauled down the hill by the trio and then hoisted up with pulley ropes for processing.

The most important thing is that I was busy with the construction of the bathhouse, and I was busy working overtime from the evening until the middle of the night when the moon was sparse.

After a hard day, when everyone washed their hands and went to sleep in the house one after another, Zhang Xiangyang looked at the bright moon in the sky, and said curiously to Zhang Bin, who was close to him: "Zhang Bin, didn't you say that the moon was smashed before?" How is it okay? ”

Zhang Bin showed a surprised expression, and then explained: "It's really broken, but it's broken in part, not all of it is broken, it's mainly in the dark side." ”

Zhang Xiangyang looked at the moon and said strangely: "I still remember the last time the moon was full, and there seemed to be no cracks on the moon?" Even the dark side should go around in circles. ”

Zhang Bin showed an embarrassed expression and didn't know how to explain.

At this time, Lingling, who had very sharp ears, walked over quickly, and looked at Zhang Xiangyang with his hands on his hips, "Brother Xiangyang, you must have been sleeping when you were in class!" Now I am the moon and you look at me! ”

Ling Ling quickly faced Zhang Xiangyang and walked around Zhang Xiangyang.

Zhang Xiangyang said suspiciously: "Then what? ”

Lingling sighed helplessly, "Stupid, can you see my ass!?" ”

Zhang Bin explained: "The moon's cloudiness is mainly due to its own rotation, but because the moon is a satellite of the earth and has always been captured by the earth, what we see is always the front of the moon, and most meteorites from outside the universe are blocked by the dark side of the moon, and this time is no exception." ”

"When a celestial body revolves around another celestial body, tidal friction occurs that slows down the rotation and eventually creates a state of continuous facing another celestial body on the same side, which is tidal locking."

Zhang Bin looked at Zhang Xiangyang and Lingling, "It's like you and Lingling, because of the relationship between orbit and gravity, there is a gravitational force between them that binds each other and does not detach, so it is not an irregular action, and the earth has always been firmly grasping the moon." ”

"Oh, I see, I see." Zhang Xiangyang nodded, "Go to sleep, I'll go to sleep." ”

Soon, Zhang Xiangyang naturally walked into the mud house.

Lingling looked skeptical, "Does he really understand or does he pretend to understand?" ”

Zhang Bin smiled, "I should understand, go to sleep, and I have to get up early tomorrow to work." ”

Everyone entered the hut to rest, and in this quiet autumn night, the moon in the sky quietly exuded a silvery white cold light.
