(Ten chapters are difficult.,I think there's only seven chapters.,The remaining three chapters.,Make it up tomorrow.,I'm sorry)

Saltpeter mine, that is, the raw material for making potassium nitrate, as far as Fang Hao knows, saltpeter ore is very rare on the original earth, but he didn't expect this coal mine to be accompanied by saltpeter mine.

Coal and potassium nitrate were the raw materials for making gunpowder, and these two raw materials happened to appear in the same mine, which was simply specially prepared by God for Fang Hao.

"Dig!" Fang Hao picked up the hoe and began to work.

Coal mines are not as good as gold and iron mines, because coal mines are relatively loose, a careless will cause a landslide, so Fang Hao is very careful when mining.

He slowly dug along the coal seam, and with each swing of his hoe, he could dig out an entire cube, nearly a ton of coal.

Saltpeter ore was relatively small, less than one-tenth of coal, but Fang Hao's mining speed was very fast, and the numbers of coal and saltpeter in Fang Hao's inventory were increasing rapidly.

For the sake of safety, Fang Hao dug forward while using the frame to make a support to prevent the coal seam above from collapsing.

He didn't stop digging until it was almost dark, he took a look at the harvest, and dug more than 3,000 tons of coal and more than 200 tons of saltpeter mines.

If used to make ammunition, these are enough for a long time.

After the two of them ate something in the mine, they didn't get out of the mine, Fang Hao built a hut in the dug mine, then made a furnace and a workbench, and began to make gunpowder and cannonball bullets.

Saltpeter ore is refined into potassium nitrate, which requires water, and there is no water in the mine, so Fang Hao can only put it aside for the time being, and wait until he goes out.

He also has a large amount of potassium nitrate in his inventory, which is enough ammo to craft right now.

Since he didn't stay here for long, Fang Hao only took a nap for a while, and then continued mining until dawn.

When mining, materials are still being crafted in the furnace, and gunpowder and ammunition are constantly being crafted in the system.

For two whole days, Fang Hao spent two whole days in mining and manufacturing ammunition, eating something when he was hungry, and taking a nap at night, his current strength, even if he didn't rest for a few days and nights, he didn't feel sleepy at all, he took a nap, it was just a habit that he had developed for a long time.

Two days later, Fang Hao packed the bullets and shells he had made and put them on the side of a road ten kilometers away from Yecheng, and let Zitong guard the side, and he returned to Yecheng alone.

Seeing Fang Hao come back, Liu Yishou was very surprised, and grabbed Fang Hao's hand when he came over, as if he was afraid that he would run away.

In the past two days, Fang Hao has not shown up, and Liu Hao has been so anxious that he thought Fang Hao had thrown his hands and left.

Although the giant cannon and turret were transported back to Yecheng and were being prepared to be installed on the city wall at this time, it was useless to have a turret without ammunition.

Because Fang Hao had asked Liu Yishou about the coal mine and silver mine before, Liu Yishou also sent people to the silver mine and the coal mine to find the two of them, but Fang Hao was mining in the depths of the mine at that time, and Liu Yishou's subordinates sent out to find Fang Hao did not find Fang Hao.

couldn't find Fang Hao, but he was in a hurry, he called Kang Jianmin, but Kang Jianmin didn't know where Fang Hao was, when Liu Yishou learned that Kang Jianmin was just a friend who met Fang Hao on the road, Liu Yishou fainted all of a sudden.

What should he do if Fang Hao doesn't say goodbye?

Just when he was so anxious that he scratched his heart, Fang Hao came back.

"City Lord Fang, you can be regarded as back, where have you been in the past two days? Let me find it so hard! ”

Fang Hao said: "Didn't I send you ammunition?" ”

"Ammunition? Where is it? Liu Yishou hurriedly asked.

"It's not far, just outside the city."

"City Lord Fang, take me to take a look."

Fang Hao smiled and said, "I have to go to your warehouse first." ”

Liu Yishou nodded again and again: "Okay, yes, I'll take you there." ”

After re-entering the warehouse, Fang Hao began to pick it up in the warehouse.

Ye Cheng had looted the treasures for decades, and although most of them were not worth much now, they still had some value to Fang Hao.

Not to mention anything else, just those ancient paintings, antiques and ancient porcelain that look very high-end and high-grade, all of them are pretending to be artifacts, if you take it back to the earth and put it in your villa, you can instantly make your residence rise several grades.

"This box, and that pile, I want all of them on this shelf, there, the row against the wall, and the ...... over there"

Fang Hao looked at these large boxes and small boxes of gold and diamonds, all kinds of treasures, one by one, and almost picked out two-thirds of the things in the warehouse.

Actually, Fang Hao is also for Ye Cheng's good, Ye Cheng wants these treasures to be completely useless, they just take up space here, they are put for a long time, they are rotten, they are broken, and they are thrown away in the end, it is better to cheapen him Fang Hao.

In these last days, these treasures are really useless.

Liu Yishou thought that just relying on Fang Hao and these people, let them take it casually, and even if they went to the sky, they couldn't take a few pieces or boxes, but now it seems that this is not the case, and Fang Hao is too ruthless.

These treasures in the warehouse, Liu Yishou knows their value, these treasures are all registered, what is the origin of this treasure, how precious it is, how rare the treasure is, how high the manufacturing cost is, he has some understanding.

Although there are a lot of treasures in the warehouse, it is like a small supermarket, no matter how many goods there are, the shopkeeper also knows how much various goods are purchased and how much they are sold at.

Seeing that most of these treasures were picked up by Fang Hao, Liu Yishou was distressed.

However, what he was even more distressed about was that seeing Fang Hao so young, did he know the true value of these treasures? If it falls into the hands of someone who doesn't know how to do it at all, it will be wasted.

However, no matter how distressed Liu Yishou was, he didn't dare to say more, and he didn't dare to show the slightest displeasure on his face.

If there were no Fang Hao's turrets and ammunition, Ye Cheng would be captured by zombies in the future, and the fate of these treasures would be even more bleak.

After Fang Hao picked out the treasures that he thought were quite good, he said unsatisfied: "That's all, you send someone to pack these up and follow me out of the city." ”

Liu Yishou didn't dare to delay at all, and hurriedly gathered people to pack all these gold diamonds and all kinds of treasures selected by Fang Hao, filling more than a dozen board cars.

With Liu Yishou and these carts, Fang Hao came to the outside of the city and found Zitong guarding the ammunition box.

As soon as Liu Yishou saw these boxes of ammunition, his eyes immediately lit up, and he had already left behind the treasures on more than a dozen board cars.

He opened several boxes, which were full of yellow bullets and huge cannonballs.

"City Lord Fang, thank you City Lord Fang!" Liu Yishou thanked Fang Hao repeatedly.
