"Report to the leader of the gods! There is a colorful mountain in front of it, black and white, red, blue, green, yellow, and purple!"

Gu Yuan asked with both joy and novelty: "What color mountain, is there a variety of colors on one mountain?"

Then I raised my binoculars and looked at it, the mountain was very large, and from a distance I could see the north-south direction, stretching for hundreds of miles, and it was really like a rainbow falling down, occupying half of the sky.

The whole mountain is sparsely vegetated, and there are many bare stones, which makes it look bare. The telescope is naturally more detailed, with huge granite reflecting a variety of colors in the setting sun.

Gu Yuan counted that there are indeed seven colors, but these seven colors are not the seven colors of the rainbow color, there are two colors of black and white, and there are no orange and blue two colors. The colors are distributed in bands.

"Wow! Labor and capital have been paid! This is clearly a ribbon vein where multiple minerals coexist! I just don't know what the main mine is?" Gu Yuan looked at it, excited, and wanted to take a step forward, but was stopped by the peasant leader who came and said that it was getting dark, and if he didn't set up camp, he wouldn't be able to see and pick up dry firewood!

Gu Yuan came back to his senses at this time, and saw that the sky was really darkening a lot, and the clouds after the sun went down were almost gone!

When I woke up, it was already the second half of the night, Gu Yuan looked at the mountain that was still slowly adding firewood to the fire around him, and was about to ask why the mountain hadn't slept yet, when the water and stone around him also woke up, and several people looked at Gu Yuan and wanted to ask what happened, but when they saw that there was nothing wrong, they fell asleep again.

Gu Yuan thought about the mine and ore for a while, and then fell asleep again. As soon as it was dawn the next day, Gu Yuan got up and added a few handfuls of firewood to the smoky fire, and after a while, the fire lit up again, and a large amount of dry firewood was on the shelf, which instantly illuminated the still dim environment around him.

When the people and the dragons and horses have woken up, and the melodious birdsong once again renders the lively atmosphere, breakfast is made. After eating, a large group of people and animals soon came to the colorful mountain, looking at this mountain full of treasures, Gu Yuan was full of emotion, relaxed and happy!

Gu Yuan first paid attention to the many large red mounds on the mountain, which turned out to be termite nests, which were all excellent weathered clays that could be used to fire pottery. If you look at the gold, it's all greasy and greasy yellow wax stone, and if you look at the golden glow mixed in with the stone, you know that this is a chalcopyrite. Gu Yuan roughly judged that it was not bad, and it could barely be regarded as a copper-rich mine.

"Dig the clay away, and the copper ore must be taken away, and you can take as much as you want!" Gu Yuan said fiercely, and he also did it, using his hands, using stone shovels, wood milling, etc., it was really difficult for them to take hard stones. After working for a while, he was sweating profusely, Gu Yuan continued to dig with stone tools, he was reluctant to use a military dagger and a military shovel, and a small gap in that guy would make him feel distressed to death.

Digging to the bottom of less than a meter, suddenly the veins changed, from strips to layers, there were layers of pyrite, are some flake stone flakes, Gu Yuan recalled a little bit of knowledge, the main component of pyrite is iron sulfide, which is different from hematite based on iron oxide.

Digging down again, it is found that there are half catties and eight taels of brass and iron ores, and there is no obvious who is associated with whom, which is a very strange phenomenon! Under normal circumstances, the two ores together are one for the main and the other for the associated ore, and here is a special case.

"This green stone is easy to explain, it is the symbol of copper mines, malachite. The copper-containing stones are all green, including jadeite! If you have too much jadeite, you can also smash the copper smelting! What are the blue and purple stones?" Gu Yuan kept imagining in his heart after digging out some blue stones on the side.

The blue and purple stones are all azurite!

The white color is Guanyin clay, refractory clay, and it is a good product for firing porcelain, mainly because it can make crucibles that melt metal. Lime and gray granite were dug up again. At this time, from the side of the granite, Gu Yuan discovered a tin ore that coexisted with it, which is also a treasure!

Copper and tin alloys, that is, bronze, can be superior to steel in some ways. Iron and tin alloy to enhance hardness and corrosion resistance.

Finally, Gu Yuan found that they had dug a total of fifty baskets of copper ore, fifty baskets of iron ore, thirty tin ores, and thirty baskets of soil on this colorful mountain. Carefully packed and placed on the back of the brute dragon, the young man rode a horse, and he could continue to train the ability of horses and men to fight.

In a good mood, Gu Yuan secretly thanked himself in his heart for the rich knowledge he had learned in the military academy and in the army, otherwise there would be no way to talk about the knowledge of animals and plants, the knowledge of ores, and the pottery and smelting techniques that will be carried out.

The way back is very short, Gu Yuan calculated, the straight-line distance to the Protoss Palace, only more than thirty miles.

"If you want to open up a straight road between Caishi Mountain and the Protoss Palace, people can go back and forth in a day, and use horses and ox carts, it will be faster. ”

Gu Yuan first imagined these prospects, and the most important thing at present was pottery and metallurgy, and first created things that were necessary for life and warfare.

The day after he returned, Gu Yuan began to work in person, and after he arranged all the people who had fallen behind, he went to dig a pit with a military round-headed shovel on the grass next to the playground. Others naturally perform their duties under the leadership of the captains of each team and the leaders of each group. For example, the peasant leader leads people to cut grass and dry grass, for example, the old man takes people to smoke, and the smoked and dried meat is stored in a winter without worrying about rotting, this primitive method has lasted for thousands of years, and it is still used in modern civilization.

Another example is that Shan and Ishi lead young men and women to practice horseback riding and archery, and Shui and Yun teach children about culture. The old man took people to cook the skin, and then handed it over to the night witch to take the woman to make leather robes and mattresses, or cut them into strips of leather.

When Gu Yuan dug the pit, he found that the soil quality here was very good, no wonder the grass on the grassland grew so luxuriantly, if it was reclaimed to grow crops, it must be fertile and fertile land! Therefore, Gu Yuan decided to wait for the copper and iron to be smelted, and he must first make some farm tools, and plant a large number of grains, pumpkins, winter melons, and hemp!

Guyuan dug pits naturally to build kilns, and kilns were built to fire pottery. In half a day, Gu Yuan built a three-story small kiln, in fact, this kiln is no different from the common people building a smokeless stove, but it is larger than the stove!

The kiln was built, but it was too wet to be used, and Gu Yuan was in a hurry to use it, so he called three teenage boys to burn a fire here and dry the kiln skin! He went to find a large stone slab and kneaded clay pots, pots, bowls, pots, amphorae, and so on on the smooth side and clay. They were pinched and put in the sun one by one, attracting a few pregnant women and children who had nothing to do.

So, Gu Yuan was afraid that the mud things he had worked so hard to make would be broken, so he sent two old men to sit here and watch!
