In Dadu, Yisima was sawing a piece of wood, and Alaowading was assembling the Hui gun. This time it was the first huge rock cannon they made in the Central Plains far away from their hometown, so they were still a little nervous.

When the last beam penetrated into the wooden tenon, the first huge rock cannon was built like this.

"Shan, this cannon has been built, please check it!" Yi Sima Yin walked forward and said respectfully that his Chinese language was not very good, and he gave people an inexplicable sense of joy.

Another man, Alao Wading, only knows how to build cannons. He can't even speak his own language, let alone Chinese.

"What are you waiting for? Test the cannon!" Borjijin, sitting on the stage, wanted to see how powerful the legendary Hui cannon was.

Yi Sima Yin waved his hand, and saw the two gunners at one end of the giant cannon pull hard, and the wooden board was upside down. The huge rock weighing hundreds of pounds rose into the air and shot out in a parabola.

It landed three hundred steps and made a deafening sound, and the earth seemed to be trembling.

The huge rock reached seven feet into the ground!

At this time, the Mongolian nobles and Han officials present were all quiet and shocked to speak.

"Khan, please forgive me for your sins!" Yi Sima said this on purpose. He clearly saw Kublai Khan's stunned expression. This was definitely an appreciation. He apologized for nothing but to increase his impression.

"You two have made great contributions, so why are you guilty?" Kublai Khan seemed to see his Mongolian army using this cannon to capture all the rich cities in the world, and he wished he could transport this cannon to the front line immediately.

"If I perform this cannon well, I can have a range of 400 steps. This time I only complete 300 steps, which is really worthy of the Khan's entrusted!" Yi Simayin was certainly not bragging. He gave him a hundred courage, and he would not dare to brag in front of the most powerful person in the world.

This time, Mongolia was very anxious and asked them to build the cannons earlier for Dahan to see, so the time was rushed. If it was not so fast, the effective range could really reach 400 steps.

"The terminator of the Song people is really powerful, but compared with this cannon, it is still a lot worse!" The Mongolian Han Prime Minister Shi Tianze took the opportunity to boast a few words.

"This cannon can deal with the threat of ending the capital and is also a powerful weapon to siege the city. There are only fifty cannons, and Xiangyang can get off!" The left prime minister Boyan saw the strategic significance of this weapon.

"Okay, four hundred steps, then I'll give you another ten days to build a huge rock cannon that can shoot four hundred steps!" Kublai Khan was in high spirits.

"It may take half a month to sweat!" Arauvadin, who had not spoken, walked up to him and said. Yisimainla couldn't even hold him back, which scared him to sweat heavily.

This stubborn guy was very dissatisfied with Dahan asking them to leave their family and go straight to a place called Xiangyang, but he just didn't have the chance to say it.

Unexpectedly, he dared to stand up and question the Khan's decision.

"Oh," Kublai Khan held up his cheek and thought for a while, "Okay, if you can reach four hundred steps with you in half a month, I will reward you!"

The two of them received the order in unison.

This place is the Xinghong Coal Farm in Hunan now. The coal seam is shallow. Even though Li Fu did not know how to mine, he saw Song Chen punching more than 50 "probe sticks" at the mining sites on various hills. Most of the probe sticks had coal. As Song Chen said, the deepest part was only ten feet, not only was it shallow, but the coal seam thickness reached more than two feet.

In short, if he picks up the treasure, these coals will bring a lot of "cash flow" to Tanzhou.

Song Chen talked a lot, and Li Fu brought a mining supervisor who was very knowledgeable. This person was not interested in Song Chen at first, thinking that the "slim bamboo pole" could not be more proficient than him who has been in the coal business all his life, but he was wrong.

The young man talked a lot. He simply designed a mine location map, how to dig a mining channel to save the most effort, whether it is a horizontal shaft or a solid well, how to drain water, separate the tunnel from the coal mining tunnel, all of which refreshed the mine supervisor.

In the end, Song Chen took out a mine lamp. Of course, it was not the mine lamp itself that conquered the mine lamp, but because he insisted on using the open lamp.

He said that a flammable and explosive gas will be produced in the coal seam. If there is an open flame underneath, once it is ignited, it will explode, affecting the safety of miners.

Logically speaking, this statement is a bit ridiculous, but this mining supervisor has been managing the coal yard all his life, and vaguely feels that what Song Chen is saying is true.

Speaking of this, the mining supervisor no longer listened to Song Chen's words in a coherent manner, but instead memorized them carefully, fearing that he would miss any one.

"It's a pity that there are very few prisoners everywhere recently. Otherwise, if a hundred people were transferred to dig, the effect would definitely be good!" Li Fu felt that there was a disadvantage.

"Uncle Li, I don't want to use prisoners for crimes, just use innocent people!" Li Fu was shocked by the plan proposed by Song Chen.

During this cooperation, the relationship between the two people quickly became involved. Song Chen called him Uncle Li, Li Fu called Song Chen Xiaochen, and Xiaochen seemed to be petty.

As soon as the three thousand stakes of "member money" was handed over, Song Chen asked him to write a "shareholding agreement" and had to stamp it with an official seal so that the kid could feel at ease.

As soon as the money was in place, he spent 1,000 guan to buy cement, 500 guan to buy anchors and other tools, and he also spent 1,000 guan to hire an engineering team to dig. Needless to say, this is the kid's property, he replied directly to Li Fu and felt like he was cheated.

Such a person doesn't want to use free labor opportunities.

"Really, Xiaochen?" Li Fu thought so. If you don't need it, I still use it with more ruthless places.

"Of course, locals can be hired to mine, and now it is the slack season, which can increase their income!" Song Chen was of course serious, because he felt that the efficiency of using criminal prisoners was low and it would not cost much more, so he could create wealth for the local area. Of course, he was also considering establishing good relations with local villagers.

"Digging coal, Song Chen, do you think you can recruit locals?" Li Fu knew that in the eyes of locals, he was a hard, tiring and dirty job, and his wages were not high, and he was very dangerous. He had basically no good family willing to do it.

"The salary at the end of a month is three stakes!" Song Chen reported this number.

"Sanguan is indeed very high in the countryside, but the coal mining job is very dangerous. Even if Sanguan is required to recruit all personnel here, it is still difficult!" Li Fu still has a good understanding of the local people. How could he let go of this opportunity to improve people's lives? What he said is indeed the truth.
