Seeing that the mountain wall was gradually reddening, and the time was almost up, Fang Ruitao quickly mobilized a clear stream from the chip and quickly sprayed it onto the mountain wall that had been burned. Pen, fun, pavilion www. biquge。 info A miracle happened, and the originally solid and inseparable mountain wall actually broke many small cracks in a crackling cracking sound.

Fang Ruitao looked at the situation in front of him, nodded with satisfaction, and then he picked up the pickaxe and gnawed into the cracks in the mountain wall with the pointed end, with just a little force, the large pieces of mountain rocks began to peel off one after another, and it didn't take much effort at all, Fang Ruitao had already penetrated nearly thirty centimeters.

"You are really creative, you actually use the principle of thermal expansion and cold contraction of objects to instantly cool down the hot rock, so that it shrinks and cracks. Fengyun No. 19 said loudly, he didn't expect that Fang Ruitao would use such a trick to open the mountain, but this approach is indeed much less labor-saving.

"Of course, it is said that in ancient China, miners did not use **, and they used this method to open mines. Even after the founding of the People's Republic of China, there was a period of war preparedness movement. At that time, due to the lack of **, many engineers still used this method when digging stone caves. Under the persuasion of his father, Fang Ruitao still made a certain amount of effort in history, and these things are quite clear.

Fengyun 19 said: "Okay, you just keep digging." If we dig up the deposits like this, we might soon be able to make a lot of good things. ”

As he spoke, Fang Ruitao's pickaxe gnawed down the last broken rock, and a gray-black crystal that was different from the sandstone was exposed. Seeing this crystal, Fang Ruitao happily threw away the pickaxe, stepped forward and stroked it and asked, "Nineteen, is this thing?"

Fengyun 19 replied affirmatively: "That's right, this is sulfur-molybdenum-tin-copper ore, you just need to mine the ore and send it into the chip space, and I will operate the smelter for you and extract them separately." ”

Fang Ruitao nodded, picked up the pickaxe again with both hands, and gnawed it down. The crystals were much more fragile than sandstone, and Fang Ruitao didn't have much effort to fire a large piece at all. Fang Ruitao's hands did not stop, and large pieces of crystals were peeled off from the ore deposit, and then they were included in the chip space.

Fang Ruitao, who has no mining experience, does not reserve any roadway vents, nor does he carry out layered excavation, he is completely unplanned and indiscriminately excavated, and there is no discipline at all.

At this time, Fang Ruitao didn't care about any sustainable development, and he didn't have any concept of a virtuous circle, he just wanted to mine as many minerals as possible in the shortest possible time to provide the necessary raw materials for his micro factory, so that the factory that was basically shut down and waiting for materials could operate.

"Master, you don't want to fill my space with this kind of mine, do you? Seeing Fang Ruitao's crazy mining, Fengyun No. 19 finally couldn't help but remind him.

"This ...... How much ore is there in the chip space now?" Fang Ruitao asked.

Fengyun 19 replied angrily: "You are only asking now, just now I exerted my battle qi with all my strength, and I dug frantically for an hour, and my space already has more than two tons of ore, and now the smelter is rapidly extracting." ”

Fang Ruitao gasped and sneered: "Mistake, mistake." You know the first time I've mined ore with my own hands, and I'm a little excited. After speaking, Fang Ruitao seemed to think of something again, and asked with a little expectation: "After digging so many mines, it should be of great use." ”

"It's basically useless. Fengyun No. 19's words poured a basin of cold water on Fang Ruitao and said: "Sulfur can be made into sulfuric acid, although this kind of thing is known as the mother of industry and has a wide range of uses, but if you want to really make something in a chemical plant, one raw material is not enough." Copper and tin can be made into bronze, but bronze can only be comparable to steel in hardness, and it is worse in toughness, not to mention that this is an alloy, and it is more difficult to return to the furnace once damaged. If you use copper alone, you can mint copper coins, but the copper content in this deposit is not high, and copper coins are basically the cost price, and you can't make money. ”

Fengyun No. 19 analyzed for a while, which made Fang Ruitao's originally excited mood completely cool, and he said indignantly: "Since it's useless, you still let me dig it?

Fengyun 19 said: "I just want you to experience mining, after all, if you want to make the factory run in the future, it is essential to mine yourself." As for digging so much, it seems that I am not responsible for it. ”

Fang Ruitao sighed and said, "Forget it, I'm really happy that I'll close the mine, let's go on the road." Fengyun 19 said: "Actually, even if you don't close it, no one will want these things, with the smelting level of this world, it is impossible to refine this kind of ore." ”

"Alright, let's move on. Fang Ruitao was extremely depressed by the blow of Fengyun 19. It took a few hours to get a bunch of mineral deposits that were not of much use, and the only benefit was that the fusion speed of the battle qi increased a lot.

After thinking about it in his heart, Fang Ruitao felt that steel was still the most useful, and if he wanted this, he naturally had to go to the mine in the village. Identifying the direction, Fang Ruitao walked quickly towards the mining site.

The iron ore mine in Lutan Village is open-pit mining, and the scale is very small, and it used to be intermittently mined, as long as it can provide enough raw materials for the blacksmith to use in the village. However, since a few days ago, all the steel weapons of Blacksmith Zhang were purchased by the caravan, and the village chief decided to send a special person to mine iron ore for a long time, and at the same time found five or six smart and clever people from the young people in the village to enrich the blacksmith shop as apprentices.

The old village chief planned to make the blacksmith shop a profit point for Lutan Village and help the entire village become rich as soon as possible, and the person in charge of mining here was Murong Yanran's elder brother Murong Hai.

From a long distance, Fang Ruitao heard the clanging sound of mining in the distance, and when he got closer, he finally saw more than a dozen mining figures. The mine is on the top of a mountain, but after years of mining, it has long become a large depression, so Fang Ruitao did not see the villagers mining at the bottom of the pit in the distance.

Seeing Fang Ruitao coming, a shirtless man with bronze muscles all over his body wiped his sweat and walked over, and said with a smile as he walked: "What kind of wind blew Little Brother Fang here, there will be times when distinguished guests come to our remote iron mine." ”

This person is the person in charge of the mine, Murong Yanran's brother Murong Hai. As an elder brother, Murong Hai naturally knew his sister's careful thoughts, so he was unusually kind to this young man who might become his brother-in-law.

Seeing Murong Hai's warm greeting, Fang Ruitao also smiled and said: "It's nothing, I just heard Bart say that the village has its own iron mine, and I want to come and see the color of the ore, maybe we can continue to improve the iron smelting process to make the steel quality better." ”
