The so-called flame mountain, to put it bluntly, is actually the underground coal seam was ignited by accident, so that the burning for many years, the surface has been greatly affected, and some places can not pass through at all, such as Xinjiang, Inner Mongolia, Shaanxi and other places in later generations have this kind of coal seam burning formation of the flame mountain, Ma Ye said that the flame mountain is this kind.

Thinking of this, Li Xiu began to explain the principle of the formation of the Flame Mountain, but Ma Ye was also very surprised after hearing it: "You said that the so-called Flame Mountain is actually formed by the burning of underground coal?" ”

"The coal is originally produced underground, and some of the coal is buried relatively shallow, which is easy to ignite in case of mountain fires and lightning strikes, and the underground coal reserves are very large, and it can even burn for a hundred years without extinguishing." Li Xiu smiled again and explained that he had also seen it from the news in later generations, as if Xinjiang had always wanted to extinguish the underground fire in the Flame Mountain, so there was some introduction to the Flame Mountain.

"I see, if you don't say it, I'm afraid I'll never think of Shi Tan." Ma Ye also said with great emotion at this time, he now has the feeling of "listening to your words is better than reading a book for ten years".

"Speaking of coal, Uncle Ma, have you ever seen a coal mine anywhere?" Li Xiu's eyes suddenly lit up at this time, just now Ma Ye asked him to think of a way to make money regardless of the four seasons, and now this charcoal is a very good thing.

"Carboniferous, what are you asking for?" Ma Ye asked again with some surprise.

"Coal is a good thing, if there is a carboniferous mine, it is simply a steady stream of gold!" Li Xiu said with a smile, China is one of the countries with the richest coal reserves in the world, and the deep coal mines are not easy to mine, but there are still many open-pit coal mines, which are all wealth given to them by God, and it would be a pity not to.

"No, this thing is of no great use, although it can be burned, and even some people used it to smelt iron in the Han Dynasty, but the iron that is smelted is scorched and brittle, and it can't be used as a weapon at all, as for the usual fire cooking, it is even more troublesome, because it is difficult to ignite, and it is poisonous, it is said that some poor people can't afford to buy firewood in winter, so they pick up some charcoal and go back to light it for heating, but in the end the whole family is poisoned to death." Ma Ye listed several Achilles heels of Shi Tan in a row.

"Haha~, it is definitely not possible to make iron directly from coal, but to process it into another fuel, as for the ignition of charcoal is very troublesome, there is a solution, and in the end the charcoal is poisonous and a little wronged, in fact, charcoal is the same as charcoal, if they are burned in a relatively closed environment, they will die in the end." After listening to Ma Ye's words, Li Xiu laughed and said, coal was discovered very early, but it was really used on a large scale until the Song Dynasty.

"Listen to you say that, Charcoal is really a treasure?" Ma Ye was surprised again at this time, he also knew that Li Xiu would not lie to himself in this kind of thing.

"Of course, but we have to find an easy mine of carboniferous before we can do it, otherwise it's all empty talk!" Li Xiu nodded affirmatively again, and then mentioned the carboniferous mine again, which is the root of everything.

"No need to look for it, I know that there is a black stone mountain in Ningzhou, which is actually an open-pit coal mine, I have also stationed troops there before, and I know the terrain over there very well, judging from the area of that black stone mountain, there should be a lot of coal in it!" Ma Ye is worthy of being well-informed when he travels south and north, and he can say a place without thinking.

"Ningzhou? Isn't it a bit far, are there any coal mines near Chang'an? Li Xiu was a little worried when he heard this, Ningzhou is next to Gyeongju, and it takes a day to get to Chang'an on horseback, if the transportation will definitely be slower, so the freight of the charcoal will go up, and the cost will definitely not go down.

"Ningzhou is not far away, it is next to the Jing River, and if you want to mine it, you can put the coal on the boat and go down the river, and you can reach Chang'an very quickly." Ma Ye is worthy of being a general who leads the troops to fight, and immediately thought of the best transportation route, but then he said with some doubts, "Boy, can you really turn coal into treasure?" ”

"Seeing is believing and hearing is false, why don't you ask Uncle Ma to let someone get some charcoal back, and I'll show you!" Li Xiu said with a smile, sometimes it is difficult to convince others with words, or it is easier to prove it with reality.

"No problem, I'll let someone go find the coal!" Ma Ye nodded immediately when he heard this, and he was also very much looking forward to Li Xiu really being able to turn charcoal into treasure, so he stood up and left after speaking.

"Wait a minute, I need a tool in addition to the coal, Uncle Ma, you can also help me build it!" Li Xiu said and asked Yuechan to take the pen and ink, and then he began to draw a drawing of a tool on the paper, and also drew an exploded diagram of the tool, the structure inside is not complicated, and there should be no problem in manufacturing it with Datang's technology.

"What is this thing for?" Ma Ye took the drawings and looked at them for a long time but didn't understand the purpose of this thing, so he couldn't help but ask.

"Hehe, keep it secret for the time being, you'll know when you make it!" Li Xiu smiled mysteriously. Seeing that Li Xiu deliberately closed the child, Ma Ye couldn't help laughing and scolding, and then stuffed the drawings into his arms and went out, he has always been a fiery character, and if he has a decision, he must do it, even if the sun is blazing outside, he can't stop him.

At that moment, Li Xiu returned to the bedroom of the inner house, but found that Princess Pingyang was humming a little song to coax Qi Niang to sleep, and Li Chengdao was playing cards with a few maids such as helmets outside, he came to Li Xiu to learn a lot of things, solitaire is one of them, and Li Xiu does not prohibit him from playing like other teachers, as long as he does not delay his study.

Li Xiu came to the bed side of the bedroom lightly, looked at Qi Niang on the bed, but found that she was already asleep, Princess Pingyang smiled a little shyly when she saw him come in, and then made a silent hand gesture to him, and then stood up gently, and the two went out of the bedroom together.

"Bothered the princess!" Out of the bedroom, Li Xiu thanked Princess Pingyang and said, Qi Niang has no mother since she was a child, although she has Li Xiu, the eldest brother, but she can't make up for the maternal love in her life, but since she came here, Princess Pingyang has been playing the role of a mother in her life.

"It's nothing, in fact, I also wish I could have a cute and sensible daughter like Qi Niang." When Princess Pingyang said this, she suddenly found that her words were a little inappropriate, and she lowered her head shyly at the moment.

"Definitely!" Li Xiu saw Princess Pingyang's shy appearance, and impulsively showed a categorical expression and said, no matter how big the gap between him and Princess Pingyang is, he can't stop him! I just don't know how the bearded guest is preparing?

At the same time, in a bustling port at the southern end of Chikushi Island, the bearded guest looked at the countless sea ships scattered on the sea, and he couldn't help but feel a little arrogant in his chest, even if he couldn't determine the Central Plains, he was a well-deserved king on this sea that was wider than the land!

"Father, the ships and supplies are almost ready, when are we going to set sail?" At this moment, I saw a young man behind the bearded guest speak, and I saw that this man was extremely handsome, even more gorgeous than a woman, and this person was Zhang Shiyi, who had been to Li Xiu at the beginning.

"Don't worry, it's the windy season at sea, and it's too risky to go to sea, and it's not too late to go to sea after the sea is calm in autumn and winter." The bearded man said very calmly, many years of sea life have already made him more familiar with the climate at sea than anyone else, and when going to sea, he must have the right time, place, and people, otherwise something will definitely happen.

"Father, the Americas are far away, and you are still needed at home, so why don't you let me go on your behalf?" At this time, Zhang Shiyi suddenly said, in fact, he was still worried that his father was getting older, although his body was still very strong, but after all, he was not as good as a young man, but he didn't dare to say this, because he knew that his father hated others saying that he was old.

"No need, as long as I don't die, there won't be any chaos at home!" The bearded guest was very stubborn, this time he went to the Americas to find high-yield crops such as sweet potatoes, but for him, it was to find a new target for himself to conquer, and only in this way could he feel that he had the meaning to live.

Seeing that his father disagreed, Zhang Shiyi also sighed helplessly, and then had to speak: "Okay, since my father is going, then I will also go with me, so that I can take care of my father's daily life, and secondly, I also want to increase my knowledge!" ”

"You're going too?" Hearing this, the bearded guest turned his head to look at Zhang Shiyi in some surprise, but quickly nodded and said, "It's okay, you should also go out and see the world, but I don't know how many dangers you will encounter when you go to the Americas this time, you have to be mentally prepared!" ”

"Hehe, father, haven't you already found the ocean current that Li Xiu said, theoretically, as long as we enter that ocean current, and then prepare enough food and water, even a raft can cross the ocean to reach the Americas, not to mention that we have the best sea ships in the world, I believe it will never be a problem to reach the Americas!" Zhang Shiyi was very confident.

"Hehe, yes, with that ocean current, it does make us more confident to reach the Americas!" The bearded guest couldn't help but smile easily when he heard this.

Don't underestimate the role of ocean currents, especially in the period of sailing ships, ocean currents are actually equivalent to super-large automatic conveyor belts at sea, as long as you find the right current, then it can quickly transport the ship to the corresponding destination, even without considering the wind direction.

However, after laughing, the bearded man looked at the sea in the east and fell into deep thought, even if he had prepared for it in advance, he still had no certainty about this trip to the Americas, and he didn't know when he would be back, but the more this happened, the more excited he felt, because he was a restless person in his bones!
