Yan Yunting and Ouyang Bingyan each used light skills, running and jumping through the mountains and forests, and ran out of the thirty-four miles in about half an hour, the closer they got to the mine, the more obvious the pungent smell of saltpeter and sulfur became.

The two of them sniffed the smell and moved forward, about two more hills, and a knock of "bang bang...... sounded in their ears, and the demonic aura in the air became more and more intense.

"Probably just ahead." Yan Yunting lowered his body, slowed down, and said to Ouyang Bingyan behind him: "You wait for me here, I'll go up and have a look first." ”

"You don't have to take care of me, I'm not as weak as you think." Ouyang Bingyan also lowered his body and climbed up the mountain with Yan Yunting.

The two of them crawled behind a boulder on the top of the hill, and looked out over the valley below—an open white mine, where forty or fifty laborers were constantly wielding pickaxes to open the mine, surrounded by a wooden fence, and two wooden towers three or four feet high at the entrance, and two groups of yaksha with steel forks patrolling the mine around.

There are three mines on the hill at the back of the mine, each connected by a track, and at regular intervals a mine cart loaded with yellow stones will be driven out of the mine, which is supposed to be sulfur.

Once the sulphur is removed from the mine, it is sorted with saltpeter in the center of the mine and loaded into larger mine carts.

"Hurry up! Come on! Yaksha wielded his long whip and spurred the laborers to work like a horse.

Working day and night, most of the laborers are yellow-skinned and thin, and some people die of exhaustion in the mine all the time.

"How can these mortals be so useless? Let's go to the nearby village and catch a batch of sturdy ones! ”

"Boss, almost all the men from the nearby villages are here."

"Then go and catch it from afar! If you really didn't, you will arrest all the old people and women! The old demon has an order, and he must gather 100,000 barrels of gunpowder in half a month! If it's delayed, you and I will have to be caught and fed to the monsters! ”

……

"Yan Shaoxia, have you thought of a good way?" Ouyang Bingyan and Yan Yunting retracted back to the back of the boulder together.

Yan Yunting shook his head: "No, the enemy is outnumbered, and it won't work to force in." ”

"Why don't you try your firecracker? See if you can ignite saltpeter and sulfur? Ouyang Bingyan proposed.

Yan Yunting still shook his head: "It shouldn't work, these saltpeters and sulfur are not pure, even if they explode, it will not be enough to blow up these monsters, but it will sacrifice those laborers." ”

"It doesn't matter if the necessary sacrifices are made, if they really let them mine 100,000 stones of gunpowder, they won't blow Kunlun Mountain to the ground?"

"Don't be in a hurry, let me think about it again."

Yan Yunting looked at the mines, fences, laborers, wooden towers, yakshas, mine caves, and mine carts again......

By this time, the minecart had been filled with more than a dozen boxes of sulfur and saltpeter, and then the laborers worked together to push the minecart out of the mine, and the minecart slowly drove to the bottom of the mountain.

"There it is! Follow me! An idea suddenly burst into Yan Yunting's mind, beckoning Ouyang Bingyan to run down the valley.

"How?"

"Let's go see the trend of the minecart first, and then find a way to steal some ore and go back, doesn't Miss Zhuo know how to configure explosives?"

"You want to blow up the mine with explosives?"

"It doesn't matter if the mine is blown up or not, as long as this track is unloaded, the ore can't be transported, I have a better idea now, but in the end, it depends on whether Miss Zhuo can make a lie. Sex. Explode. Medicine comes. ”

So, the two chased the minecart and ran to the bottom of the mountain.

The mine road is built from top to bottom, the principle is to use potential energy to pull the minecart to transport, this transportation line is not short, at least there is a seventy or eighty miles of road, the speed of the minecart is very fast, until the second half of the terrain is flat before slowly descending.

By the time the minecart had come to a complete stop, it had crossed the entire hill and arrived at the next sorting station. There is also a group of laborers at the sorting station, who are responsible for unloading and loading the ore, and after loading the ore into the truck, it is pulled by a strong orc and transported to Kunyu City.

When the empty minecart is unloaded, a leash is attached, and then the empty minecart is pulled back with a mechanism in the same way as a cable car, until it returns to the mine to load the next batch of goods.

"The wisdom of our ancestors is all cheap for these monsters, it's really hateful!" Ouyang Bingyan scolded secretly.

"It's called, youkai are not scary, but I'm afraid that youkai are educated...... But demons are demons, and although they are strong and strong, their brains will never catch up with humans. ”

Yan Yunting retreated thirty miles back, and after the towed minecart drove by, he secretly jumped down the valley and cut off a section of the track directly, so that at the speed of a fully loaded minecart, he would definitely derail here.

The two lurked in the woods beside the railroad tracks, quietly waiting for the next minecart.

About two hours later, the sound of a speeding train echoed through the valley with the sound of a speeding train .......

"Attention, it's coming." Yan Yunting reminded.

Sure enough, a minecart slid down the mountain at a rapid pace, and when it drove past the broken track, "Bang! "No accident, the minecart derailed, and more than a dozen truckloads of ore were spilled all over the ground.

"Master Ouyang, you hold sulfur, I hold saltpeter, try to install as much as possible!"

Yan Yunting and Ouyang Bingyan quickly drilled out of the woods and grabbed it!

Yan Yunting took off his coat, wrapped a few large lumps of saltpeter on his shoulders, and stuffed two lumps into his sleeves, pockets, and even the crotch of his pants, and after a while, he seemed to have gained a full circle of weight.

Ouyang Bingyan couldn't help laughing: "If you stuff the stone into your pants, aren't you afraid of it?" ”

Yan Yunting smiled: "Harm! I can't care so much, these saltpeters are not pure in the first place, and I can't go wrong if I bring more back. ”

Ouyang Bingyan also followed Yan Yunting's example, and took off her coat to carry sulfur, of course she was much gentler and would not stuff stones into her pants.

Yan Yunting loaded about three hundred catties of saltpeter, and Ouyang Bingyan also loaded nearly a hundred catties of sulfur, and the handling of them with bare hands was really limited, and the two of them did not fight for more, so they left the valley immediately while the Yaksha had not found out.

The two carried hundreds of catties of ore, and it was not easy to walk the mountain road, so they rested three times before returning to the post station.

"Miss Zhuo, we brought back saltpeter and sulfur, do you see enough?" Yan Yunting shook out the back on his back, the one in his arms, the other in his waist, and the one hidden in his crotch.

Ding Jiujiu covered his mouth and smiled, and was a little disgusted: "Anyway, can you not want it in the crotch, it's disgusting......"

"How could you not want to! This is Lao Tzu from seventy or eighty miles away, with hard work! Yan Yunting said: "Don't talk about the wind and cold, why don't you make a bowl of wine for Lao Tzu to quench your thirst!" ”

"Okay, good, seeing that you are working so hard, this girl will serve you this time." Ding Jiujiu smiled, turned around and walked into the post station.
