After resting in the canyon for an hour, the team continued its journey until sunset, when it finally reached a valley.

This valley is very large, there are hundreds of soldiers guarding the entrance, many platforms have been dug out of the surrounding mountains, there are crossbowmen watching on it, and even Yang Yifei saw the bed crossbow used to defend the city.

The captain of the group handed over to the Taniguchi guard, and the slaves were led into the valley by some other soldiers.

The soldiers, who were in charge of escorting the slaves, went to a camp on the left side of the valley, apparently returning.

According to Yang Yifei's observation, from the scale of the camp and the number of tents inside, it can be roughly estimated that the defenders of this mine are no less than five or six thousand.

In addition to the defenders, there were many military laborers who traveled back and forth through the valley, hauling cartloads of ore to a large tent on the right.

Although these laborers were also sold as coolies, their status and situation were obviously much better than those of slaves, and they had the opportunity to retire and return home after a certain number of years of servitude.

Yang Yifei was secretly curious in his heart, with so many troops guarding, what kind of mine is this? Is it a gold and silver mine?

Because it was too far away, Yang Yifei couldn't see what the ore in the cart looked like, but he had a feeling that from the moment he entered this valley, he was inexplicably refreshed and felt comfortable.

After thinking about it, Yang Yifei and the other slaves were taken to a position hundreds of zhang away from the valley mouth, where there was a huge mine.

It turned out that this was not a cavern-type mine with a hole in the mountain wall, but a pit dug into the ground.

Among the thirty slaves, except for Yang Yifei and Ma Yan, the remaining twenty-eight people looked at the bottomless pit in horror, their eyes full of despair.

Yang Yifei, the traverser, and young Ma Yan didn't know the horror of this mine, but most of them knew something.

Ma Yan was not energetic due to the injuries on his body, and was supported by Yang Yifei and hung on Yang Yifei's body like a cloth bag, but Yang Yifei was looking at the mine.

The pit is nearly three zhang in diameter, like a toothless mouth open to the sky, and around the pit, there are four slings distributed at 90 degrees.

One of these slings would occasionally move, turning the handle from some servant to lift up the ore dug up by the men below.

It was only at this moment that Yang Yifei finally saw the appearance of those ores, which were an ore that he had never seen before.

The surface of those ores is some light-colored rocks, and the color of moon white is faintly revealed inside, and the so-called moon white is the white color of the moon.

In fact, the white of the moon has some light blue, so the color of white with blue is called moon white.

For the time being, he couldn't figure out what kind of ore these ores were, so Yang Yifei didn't pay much attention to it, and he would naturally know in the future, and he continued to observe the situation around the pit.

Glanced around, but couldn't find anything like a lift for people to get on and off, at first Yang Yifei didn't understand why, and after thinking for a while, it suddenly dawned on him.

For these armies, after they go down to the mines, they are no different from the dead, and after they go down, they don't have to think about coming up anymore, and the only end of these slaves is to die below.

And these sergeants and laborers will never go down into this pit, so naturally there is no need for any lifting equipment.

Seeing this, a wave of anger rose from the bottom of Yang Yifei's heart, although he already knew that this world was still in a slave society, but he didn't take human life seriously, Yang Yifei's heart still couldn't suppress boundless anger.

At this moment, he already understood what he had to do when he crossed into this world.

Quite simply, just like the revolutionary ancestors on the earth did, overthrow the barbaric rule of this world, not to mention the establishment of a modern society of democracy and freedom, at least let the slave society transition to a feudal society.

Yang Yifei is not a virgin, but after all, he has been a soldier of the people for seven years, and his sense of social responsibility is much stronger than that of ordinary people.

However, that is the general direction in the future, for now, it is better to wait until the heavens are shuttled, and the strength is enough to escape from here.

But it wasn't easy, the mine was located in a valley surrounded by mountains, with only one entrance and exit.

And on the mountains on all sides, there are soldiers guarding them, and the strong bows and crossbows in their hands are no less threatening than the devil's 38 big covers.

The crossbow is even more terrifying, the elephant can give you a penetration, and there are thousands of soldiers on the ground, who want to rush out completely, unless you drive a tank or wear a steel suit, you can fly.

Just as Yang Yifei was thinking, the soldiers began to untie the handcuffs and chains for them.

In order to prevent anyone from making trouble, a platoon of soldiers pointed their spears at them, and anyone dared to make a move, and the sharp spear would not hesitate to poke out.

Yang Yifei found that as soon as the slave in front of him untied the handcuffs, he was carried by two soldiers and thrown into the pit.

"Ahhh......h

"Puff"

The slave who was thrown into the pit let out a series of terrible screams, which made Yang Yifei's heart tighten, and only when he heard the sound of heavy objects falling into the water sounded, he secretly breathed a sigh of relief, it turned out that there was a waterhole below.

After Yang Yifei and Ma Yan's handcuffs were untied, the soldiers were about to come and throw them, so they heard Yang Yifei say: "Don't dare to have Master Lao, let's go down by ourselves." ”

There is a big difference between being thrown down and jumping off by yourself, one is psychologically prepared and can adjust the posture of falling into the water by himself, and if he is thrown down, it is inevitable that his body shape will be uncontrollable and easy to choke.

The soldier nodded with satisfaction, Yang Yifei was tall and big, and it took a lot of effort for them to throw people, "Count your kid acquaintance, go!" ”

Yang Yifei helped Ma Yan to the edge of the mine, smiled at Ma Yan who was full of fear, and said softly: "Don't be afraid, close your mouth and nose and hold your breath, in the future, our brothers will depend on each other." ”

Ma Yan looked at Yang Yifei weakly, nodded emphatically, and then held his breath.

Yang Yifei helped Ma Yan and jumped down the pit.

The bodies of the two fell rapidly, the surrounding environment became darker and darker, and they fell about three or four feet, and a flickering light appeared under their feet.

"Puff"

The two of them fell into the water smoothly, the pool was not very deep, but it was enough to cushion the impact of the fall.

After Yang Yifei's body was buffered by the water, his feet reached the bottom of the pool, and his body squatted slightly, which completely buffered the inertia of falling.

This is also the advantage of jumping by yourself, if you are thrown down, not to mention the damage of slapping on the water, the back of the buttocks will inevitably have a close contact with the bottom of the pool, even if it is not injured, it will hurt for a while.

Yang Yifei quickly stood up from the water, the depth of the waterhole was only up to his chest, and Ma Yan was a cut shorter than him, but he was only submerged by his neck.

They were the last to come down, and there was no one behind, but the people who had been thrown down had been dragged to shore, and they didn't hit anyone.

With the faint light coming from the hole above, Yang Yifei could see clearly that at this time, there were many people on the banks on the left and right sides of the waterhole who were silently watching them.
