In the dry river valley, the sound of hammering echoed for a while. Gao Jin was actually very dissatisfied with the hammer he got from Wei Lianhai. As a former geological team member, the compass magnifying glass geological hammer is the three treasures he carries, especially the geological hammer, which is even more a person who eats.

Gao Jin's hammer is used by the caravan to set up tents and connect vans. There is no need to mention the workmanship. The key is that the material of the hammer is not very good, and he dare not use too much force, for fear of breaking the hammer.

Seeing Gao Jin knocking on the rocks east and west, Old Chen's mouth was already open. He had seen mining people, but he had never seen Gao Jin like this. Even though he had never talked much, he couldn't help but want to make a few words of teasing and let Gao Jin go back, saving his energy here.

"Uncle Chen, Uncle Chen..."

Just as Old Chen was thinking about how to say nothing so that he would not hurt Gao Jin's ambition, he suddenly heard Gao Jin's cry of joy. When he raised his head in a daze, he saw a touch of blackness coming from Gao Jin on the back of a rock, smashing it with the broken hammer.

"I really saw coal? How could this happen..."

Old Chen was stunned for a moment. Gao Jin said he wanted to come out to find a mine. He really thought he was a teenager. He thought he had read a book or two or didn't know who had compiled allusions and fooled it, so he wanted to show it. Why did he really find this? It's really coal? He didn't know how he got through it. He stood beside Gao Jin, wiped it with his hand, and smiled foolishly at the cracks in the broken rock formation. It was really coal.

Coal is really worth a lot of money, but it is only one ounce of silver per hundred kilograms, but even so it is not affordable for ordinary people.

What's more, if it is really like Gao Jin said that the valley is covered with coal fields, even if coal is not valuable, it will be a great fortune if it is large. It's just that everything is inconvenient outside the wall. How can I dig it out and toss it back? It's really troublesome.

Gao Jin didn't know that Old Chen had thought so far. He was lucky. The huge rock under his feet was obviously washed down from the hills on the side of the valley. The sun and wind erosion and the water from the Kuye River were washed down. The rock layer outside was already very thin. Even if he was not discovered, he would probably disintegrate in another year or two, and the coal inside would be washed downstream by the flood of Kuye River.

Thanks to this area full of coal, it is not a miracle that it can be found so easily. It is just that I have mastered advanced methods that are not available in this era.

"Erlang, go back and report the message, I'll watch here."

Old Chen seemed to have suddenly come back to his senses, and then said to Gao Jin that the coal in this huge rock would not make Old Chen feel confused, but a coal field could not help but think about it. He is from Fugu County. There is a powerful man in his hometown who opened a coal mine, with nearly a hundred horse teams and thousands of people working in the mine.

"Uncle Chen, don't be so nervous, let's go back together."

Gao Jin did not feel much emotion. In later generations, Shenmu County, the area along the banks of the Kuye River can be said to be everywhere. When he joined the geological team, he heard his predecessors say that Shenmu County was begging for food with a golden rice bowl. Now he can be sure that there is a coal field near the valley, but it is not easy to mine in these days, not to mention that it is a hundred miles away from the side wall.

Old Chen didn't expect that after finding the mine, Gao Jin, who should have been happiest, was so calm. His head, which was originally a little hot, couldn't help but calm down. He never talked much and rarely praised others, looked at Gao Jin's face and couldn't help but sigh, "It's amazing, it's amazing!"

...

The sun shone brightly, Gao Chong in the caravan looked at Lao Chen and Gao Jin who were riding back. He calculated the time. It was only less than an hour since they went out. When they came back so soon, I guess this kid should have been slapped. Is this mine so easy to find?

The two of them rode their horses closer, but found that Old Chen, who had always been serious, looked a little strange. Gao Jin immediately greeted Gao Chong, and Lao Chen came to Gao Chong and whispered a few words. Gao Chong couldn't help but be surprised and looked at Gao Jin in shock.

He really didn't expect Gao Jin to go out to find a mine, but he found it. Although coal is not as valuable as charcoal, it is better because it is large and cheap. If it is really a large piece of coal field that can be mined on a large scale, it is indeed a way to make a fortune. However, this coal field is too far away from the wall, and it is extremely troublesome for mining and transportation. For Gao Chong, it is really like a chicken rib, which is tasteless to eat, and it is a pity to abandon it.

"Don't make a statement for now." Gao Chong could only give in the last instructions, but he couldn't speak any more when he wanted to teach his son a lesson. Now he really didn't know whether this son really learned the ability to steer the geometry from an idle book, or was it just that he had good luck that the blind cat met a dead mouse.

"Dad, don't worry, my child knows the importance." Gao Jin nodded. Mining is not a simple matter. He didn't care about the coal fields in the river valley. At present, the fuel is still mainly charcoal and firewood, and not many people use coal. The coal fields in Shenmu County are all undeveloped virgin land. When the caravan goes out to the bush, they can be found everywhere.

The coalfield matter was hidden, but Gao Chong found that the rock strata containing coal was not wasted. It was bitter and cold outside the frontier. They used camel manure to make fire at night, and they also had to collect nearby firewood as fire leads. With coal, although they still had to use mixed soil, it was still more troublesome than using it. Camel manure with extremely large smoke was much more convenient.

So when the caravan continued to move forward, he went to the valley that Gaojin had surveyed. It was only three or five miles away from the banks of the Kuye River, and it could not delay too much trip.

When they found the huge rock of three or four people, the guys in the convoy took some shovels and other tools and knocked down the rock outside under Gao Jin's leadership, and soon exposed the black coal inside.

"It seems that you have to bring some family items when you go out in the future." Wei Lianhai looked at Gao Jin, who was mixed with a group of friends, whose face was dyed black with coal ash, and said to Gao Chong.

They went out to the fortress to do business with the Mongolians. Cotton salt goods and ironware were the most popular goods. It was easy to say that these cotton salt goods were strictly prohibited from smuggling by the imperial court. Of course, this ban was a joke for the big merchants who were connected to the General's Mansion. But for the Gao family caravan, ironware such as contraband could only be a small fuss. Bringing some iron pots and iron tools was the limit. Moreover, this was the familiar Mongolian tribe who ordered the order with them.

"This trip brought small people in and out, I made a profit."

Gao Chong murmured to himself that this time he took his son out of the frontier. First, he took his son to gain knowledge and let the old brothers see if Xiao Jin could run the caravan in the future. Second, the father and son have neglected communication over the years. Although Xiao Jin practices martial arts and studies, he is a little taciturn. Those who don’t know think he is stupid at home.

"I made money, I made money. I broke so many large pieces of coal and loaded them on the truck. I could load thousands of pounds and exchange them for a lot of fur goods. And Erlang has the ability to prospect..." Wei Lianhai said with a sensation. Coal is not valuable, and it will cost transportation capacity to transport it back. However, the Mongolians also know how to use coal. The caravan continued to move forward and a tribe that was familiar with them, which happened to be given to them.

"Old Wei, Erlang is good at prospecting, don't make any public statements, and he just told the public that he happened to meet him." Gao Chong felt it was hard to say whether his son had the ability to prospect, but this mine was real!

The surface of the rock layer with coal had been eroded by the sun and wind. The eight guys and Gao Jin took turns to clean up the coal they could dig and loaded them with several large vans. This kind of van was the main force of the car camp invented by Grandpa Qi when he was stationed in Jiliao. It was usually used to load goods, but when encountering enemies, it could form a formation, and the cargo capacity was not small.

After loading several trucks of coal, the caravans put on some loose soil and covered them. The caravans slowly set off again. One day or so, they were a Mongolian tribe that they were still familiar with. They had done several business operations there, and the caravans could repair and rest, and also inquire about the news about the Mongolian tribes in the Hetao region.

Along the way, the caravan guys looked at Gao Jin with envy. The young master was very lucky. He could pick up several trucks of coal after going out for a casual walk. He could only earn more than a dozen taels of silver. It was enough to marry a eldest daughter as a wife.

The guys' eyes were fine, Gao Jin didn't care at all, but the curious look that Mulan looked at him when she circled around him made him feel uncomfortable, "Mulan, why do you think of me like this? Isn't there any blur on my face?"

Mulan didn't answer, but she was still confused. She grew up with Gao Jin since she was a child. In the past year, her adoptive father Wei Lianhai asked her to go out with the caravan and teach her some experience in the world step by step. She had not been with Gao Jin for several months.

But even so, Mulan believes that the person who knows Gao Jin best in the world must be herself. From the preparations before going out to the frontier, until yesterday when Gao Jin was chasing a horse thief, Gao Jin was still the cold-hearted and unspeakable young master who was familiar to Mulan. However, after falling off the horse once, the young master seemed to have become a different person, much cheerful, and then he could dig coal...

Shortly after leaving the valley, the sun was setting westward. The caravan did not continue to move forward, but chose to camp on the bank of the river. Gao Jin naturally led the caravan's men to camp. His father used military methods to manage the caravan. Although these men did not have to fight with horse thieves, there was no point mistake in other logistics matters.

After setting up the tent, connecting the vans together, and setting up a camp sentry, everyone had just relaxed and made a fire to cook. Because there were several trucks of coal, at Gao Jin's suggestion, the guys burned water from the Kuye River and boiled all the water.
