Limestone, also known as flake stone, is widely distributed and has a wide range of uses. In the present primitive period, the main use of pen & fun & pavilion www.biquge.info is as a bond, so that you can bond stones to build walls and smear walls.

Lime with sand in the addition of water, it becomes lime mortar, which can be used to pave the ground, the advantage is moisture-proof, the disadvantage is that it is not durable, it will produce moss after a long time, and it will be slippery in rainy days.

But as long as there is a lime dam, it will be much more convenient to dry rice in the future, and there is no need to worry about stone seeds mixed into the millet, and there will be no tragedy of mold and germination because there are too many millet that cannot be dried.

In addition, limestone can be calcined if it is more than 800 degrees, and it is best to calcine it at more than 1100 degrees, and the lower the temperature, the longer the calcination time. But if the limestone is small, then it's fine.

The limestone I see now is not too big, it is just too suitable, and if it is big, it will have to be cracked.

Calcined limestone first, as well as dog's head gold or something, is of great help to smelting copper ore, and the accumulation of experience is the most valuable.

Looking at these mountains, he suddenly thought that a fire had been burned, and it would be convenient to cut the limestone at that time, of course, this was just to think about who could extinguish the fire if the entire mountain range was set on fire.

"What's the use of these stones?" Chun, as a confidant, watched Su Yang grow up step by step, and he still caught the goblin he ate at the beginning. So he is very familiar with Su Yang's habits, and he will only be so excited when he finds good things.

"It's so useful that the Great Wall uses lime as a binder." Of course, lime is only the main raw material for bonding.

Haru didn't understand at all, but he didn't ask too much, and he would definitely know when he should know.

While there was still time, the team continued to march forward, and after crossing a large mountain, it was almost dark. At this rate, I'm afraid it won't be able to reach in five days. I don't know if there is a salt family to start or not, at first it was different, but in the end it must be the same way.

Maybe other alliances will send people to learn witchcraft this year, but it's just a possibility. Ten years is too long to be affordable, and not necessarily as ambitious.

At this time they came to a small stream, where eighty men were stationed, ready to spend the night, firewood was necessary, although there were wild beasts crying on the cliffs on both sides, but it felt very far away, neither beasts nor men could run, hunting and being raided were not realistic.

I brought a lot of food out, and it was enough all the way, but I couldn't sit on the mountain and eat empty, but I didn't have time to hunt today.

Zhu Rong quickly used flint to make a fire, and Gonggong had already touched the water, one of these two people liked fire, the other liked water, a little older than him, eleven years old.

But it can be regarded as stepping on the edge of learning witches, he brought high-end materials from the tribe, and may consider letting Zhu Rong also work together to learn witches, because both of them are his good helpers, and they have an advantage in age.

The fire was lit, and firewood was found from nearby. Gonggong actually touched the fish and shrimp from the creek, and it was skillful to catch fish, either choosing the location where the live water flowed in, or under the grass on the side, or in the deep water.

"Sue, there are a lot of fish and shrimp!" Co-workers are very excited, he grew up by the big river and likes to catch things in the water.

"I'll see." Because of the hurry, there is no large-scale fishing on the Xiong's side, and after a day's journey, it is naturally best to eat fresh food from the river.

As far as the eye can see, the bamboo basket of the co-workers contains many scaleless white fish two fingers wide, which are actually scaly, but too thin. There are also black-backed prawns, which are very large, and I saw them for the first time. In addition, there are small fish and shrimp, which are blessed.

Even if more people are allowed to fish, just use bamboo baskets, and if there are big fish using nets, everyone is full of energy.

Su Yang was not idle, he checked on the edge of the stream, and soon found a place with soft soil, this kind of environment is similar to the field mud, maybe there will be yellow eels and loaches or the like, I haven't really caught it before, but it doesn't mean that there is none. In addition, you may be able to touch a soft-shelled turtle or something.

The red wolf that was brought out was also sniffing by the river, and the smell of fish excited him, and the dog also eats fish, and can digest the spines of small fish, and even the spines of large fish can eat their stomachs.

"There really are holes!" He found that there were small holes in the soil, and in modern times, he could drill a finger into them and follow the path of the hole to the bottom, and he would often be able to catch loaches or yellow eels.

Crabs can also burrow, but the hole is very large, the hole of the loach and the eel seems to be similar, and the experienced person can tell the difference, one has a flatter hole, the other is rounder, and smaller.

After moving his fingers, he finally called the co-worker over, in case he touched something that bited, at least it wasn't that he was injured.

"Co-worker, you do this, you do this. Got it? ”

"Got it." Gonggong was really a good boy, and immediately drilled a finger into it, and soon, the whole hand sank into the mud, and suddenly pulled it out, with a golden thing between his fingers.

"Quick, throw it on the shore."

Su Yang was extremely excited, this might have been an eel or something, but after he saw it, how did he think it was a loach?

Yellow eels are very different from loaches, but they tend to be symbiotic, with relatively more loaches and fewer yellow eels. However, the loach is generally blue-yellow or grayish-brown, but the one in front of the eyes is different, the whole body is golden, the mouth is four pairs of whiskers, and the eyes are black.

Although it struggles hard in its hand, it will not bite, and looking at the tail and body shape, it is indeed a loach.

A golden loach, is this a dragon loach?

No matter how I put it into the clay pot first, and then let the co-workers catch it, and when the sky was out of sight, I had already caught more than a dozen, all of which were golden loaches, and I don't know what the taste was.

By the light of the fire, the belly of the dragon loach was quickly cut with a veterinarian knife, which was pressed on the wood, and the masters all handled the internal organs like this, and they were all clean with a knife and a scrape.

Other small fish do not need to be gutted, they can be fried directly in the oil pan, the oil is the fat of the mammoth, which is equivalent to frying fish, and you can fry the fish bones to eat.

The black-backed prawns are also easy to handle, just twist the head off, pull out a hanging thin intestine, and then wash the shrimp belly.

In addition, I boiled a pot of fish soup, boiled the meat as long as the soup, put a little salt is delicious, in fact, it is also a little fishy, but it is this original ecology.

The prawns are also boiled in clear soup, because there is no seasoning, the simplest cooking is steaming, and cooking is faster, and some peppercorns can be put in the soup to suppress the fishy smell, and pepper and other seasonings have not been found for the time being.

Finally, there were more than a dozen dragon loaches, and he used a more primitive method, grabbing a handful of dry river sand, mixing it with pickled wild vegetables, and then putting the dragon loach in and stir-frying, which was similar to the method of frying peanuts and melon seeds.

"Jiang Li, you come and help me fry like this." He found a good helper, but he ate something else first, and he was hungry. (To be continued.) )
