Yan Sihai nodded, and the two walked forward into the woods.

The woods were dark and secluded.

The eyes of the two of them were always looking straight ahead, Wan Chaoyang was quite calm, but sweat was already on Yan Sihai's forehead.

It's so quiet, so quiet that there is no sound of birds, beasts and insects, it's like a dead forest.

And Yan Sihai felt that every step he stepped on the ground, there was a soft feeling, the land in this forest was much softer than ordinary ground, an indescribable feeling, which made Yan Sihai extremely uneasy.

It's like stepping on farmland.

And as Wan Chaoyang said, as soon as he walked into this forest, he felt that there were countless pairs of eyes staring at him.

It was about a long time, and a glimmer of dawn appeared in front of Yan Sihai's eyes, and in front of the forest, light began to shine in.

This shows that they have come to an end.

However, as Yan Sihai walked forward, a strong wind howled, and as he got closer to the exit of the woods, the wind became more and more violent.

Until they walked out of the forest, Yan Sihai was shocked to find that at the end of the forest, there was actually a cliff!

The wind whistled towards his face, and Yan Sihai's eyes were full of shock.

Wan Chaoyang looked at Yan Sihai's expression and smiled

"The first time I came, I was as surprised as you did."

Yan Sihai smiled bitterly

"If I'm not mistaken, this part of the Central Plains is all plains, and there shouldn't be such cliffs."

"Unless, it's a man-made digging!"

He licked his tongue and laughed

"Now, the old man is becoming more and more interested in this white area."

His head poked down

"This cliff doesn't look deep, and even then, it will take several months for the manpower to dig it, and it looks like someone has already started planning here."

At this time, Wan Chaoyang grabbed Yan Sihai's hand, and the two jumped down, Yan Sihai looked at Wan Chaoyang with a desperate face, but saw that the two did not fall after jumping down, Wan Chaoyang's other hand was stuck into a rock on the cliff, and the five finger holes were clearly visible on the cliff.

Yan Sihai gasped

"Your finger is a little scary."

Wan Chaoyang said with a smile

"This hole was reserved here when I came last time, except for Brother Chang An's pen and flower, who can deduct such a deep finger hole with one finger."

Saying that, the two of them swung back and forth on the cliff by inertia, and Wan Chaoyang took off again, and the two fell straight down.

But what they didn't expect was that they didn't fall off the cliff, but for a moment, Yan Sihai felt that he was standing on the flat ground, and when he looked up, there was a raised platform a few feet below the cliff, as long as people found the location of the fall, they could land firmly on this raised platform.

A sense of busyness came to his face, and a hole appeared in front of Yan Sihai, and inside the cave, people came and went, and baskets of stones were constantly being carried back and forth.

"You two! What the hell! ”

A strong man saw them, and he seemed to be the steward of the place.

Wan Chaoyang restrained his expression and said with a smile

"Lord Li, I, Xiao Lu, who was sent by Steward Ping a few days ago to inquire about the progress."

This strong man is Li Er, who is also the person in charge of the white area, a few days ago, Wan Chaoyang mixed into the white area under the pretense of Pingchuan's name.

"It's you, what, what are you doing here?"

Li Er glanced at Yan Sihai on the side, his face full of vigilance.

"I want to find an errand for my grandfather here, I think this white area is much easier than outside, isn't this here to ask Lord Li."

As he spoke, Wan Chaoyang took out a broken money bag from his waist and handed it to Li Er tremblingly.

Li Er took the money bag, weighed it a few times, and nodded

"Okay, but ......"

He suddenly came to Yan Sihai's eyes and said viciously

"Don't run around, don't look around, just take care of your own work."

Yan Sihai nodded hurriedly

"Okay, okay, thank you, Lord Li."

"Come with me."

Li Er took Yan Sihai into the underground mine, but Yan Sihai felt more and more strange.

It stands to reason that they are now walking back, under the forest above, and Yan Sihai finally understands why the forest above is so soft to step on, the forest is obviously hollowed out from the top to the bottom, and then spread a thick layer of soil, and then plant a forest on top of the soil, so that he can be unaware.

However, in such a place, will there really be a mine?

Soon, his doubts were dispelled, and he followed Li Er all the way, and found that this place was completely different from the quarries in the outside world, surrounded by rock walls and mud walls, not to mention that no one was mining at all.

He took a closer look, and in addition to the people in it constantly carrying baskets of ore from nowhere, in every other area, he would see several people in groups, and there was a large boiler next to it, and someone put white stones together with baskets and put them into the pot to steam.

Yan Sihai frowned, he didn't understand ores, so naturally he couldn't understand what they were doing.

"Keep up!"

Li Er's urging voice came from the front.

Soon after, they came to the depths of the cave, but saw a huge mountain of white crystals leaping in front of Yan Sihai's eyes.

The white stone mountain was almost touching the top of the cave, Yan Sihai almost exclaimed, but fortunately he still held back.

Is this the White Zone, he thought to himself.

And those white stones were piled up in a mountain, one after another, exuding an indescribable smell.

It was the smell of fireworks, Yan Sihai's eyes lit up, and it was very similar to the usual smell of fireworks.

Saltpeter, these white stones are saltpeter.

Even if Yan Sihaidang figured it out, this so-called white area turned out to be a huge saltpeter processing area!

No, Yan Sihai thought about it, they just had a saltpeter mining area outside the quarry, and there was also a special processing area, why was there a secret processing site here?

"You're right here."

Li Er pointed to the group of people sitting in front of the saltpeter mountain, Yan Sihai found that the people here were all older, but he saw that those people were holding a brush in their hands, applying paint to those white saltpeters.

"Learn from them."

"You!"

Li Er casually pointed to an old man who looked to be in his sixties

"Teach him how to do it."

Immediately, Li Er patted Yan Sihai's shoulder meaningfully, perhaps reaping the benefits, and he was much kinder at this moment than when he was outside the cave.

"Do a good job, and I won't treat you badly in terms of wages."

With that, he left.

The old man waved his hand and motioned for Yan Sihai to sit down next to him.

The corners of Yan Sihai's mouth bent, and he leaned up, but the old man didn't speak, pointed to the saltpeter in his hand, and motioned him to watch his demonstration.

I saw that the old man casually grabbed a piece of saltpeter from the saltpeter mountain, which scared Yan Sihai into a cold sweat

"Be careful, don't blow up."

This is all processed saltpeter, and if you are not careful, it is really possible to blow up.

The old man didn't care, and picked up the brush in his hand, and there was a bucket beside him, which was full of earth-colored viscous liquid, and dipped the brush in the liquid, and easily brushed the whole saltpeter into an earthy color.

The old man showed the stone to Yan Sihai, and then put it into the basket on the side, only to see that the basket was already filled with half a frame of stones.

Yan Sihai understood that their job was to disguise these saltpeters as ordinary stones.

He sneered to himself, this quarry was really weird everywhere.

"Bang Bang!"

But at this moment, a burst of clapping came from outside the cave, and Li Er's voice sounded

"The old rules!"

"Boom!"

Then, the whole cave shook violently, Yan Sihai was shocked, and there was a sound of a boulder rubbing the ground behind him, and then "Bang!" There was a terrifying loud noise, the dust was filled, Yan Sihai looked back, but saw that the entrance of the cave was directly sealed by a broken dragon stone!

It's a trap! Yan Sihai secretly said that it was not good, he looked around, but saw that in addition to these laborers, Li and other officers and soldiers had all left here.

He patted his head and secretly scolded himself for being careless, no wonder Li Er was so easy to deceive, like a lie made up casually by Chaoyang, he believed it without asking for verification.

It's just that he doesn't care whether it's true or not, and he will always be sealed in this cave and won't see the light of day.

But the development of things continued to exceed Yan Sihai's expectations, not long after the Broken Dragon Stone fell, it was pitch black in the cave, but many torches slowly appeared.

Those laborers actually stopped their work at this moment and raised the torches that seemed to have been prepared a long time ago, and then Yan Sihai was surprised to find that the old men beside him also stood up and raised the torches.

What's even more sensational is that those laborers actually walked slowly towards him in unison!

Yan Sihai's expression was ugly

"What are you doing!"

No one answered him, and everyone surrounded him until they surrounded him in a corner, and countless torches reflected on his face, shining Yan Sihai's face with red.

Suddenly, an old man opened his mouth towards him, and then everyone slowly opened their mouths, Yan Sihai's face was shocked, he found that these people had their tongues cut off!

No wonder since he entered the cave, except for those officers and soldiers, he has not found a single person making a sound, no wonder the old man has not spoken!

Yan Sihai quickly calmed down, as a ghost doctor, he naturally saw a lot more than this terrifying scene.

The sleeves were agitated, and the two pairs of cold green light were like night pearls in the dark night.

In an instant, two snakes burst out of his sleeves, and the laborers showed fear when they saw this, and they withdrew one after another.

Yan Sihai completely understood at this moment that Li Er's so-called old rule meant that the laborers who came here had to become mute like these people.

"Humph!"

He snorted coldly and forced his eyes on everyone, but for a while, no one dared to take a step forward.

Don't look at his majesty at the moment, but there is no bottom in his heart, just now he looked at those people's mouths, everyone's wounds are extremely smooth, obviously caused by a master's blow, that is to say, there are definitely more than these laborers here now.

Before he could figure it out, two cold rays struck and stabbed the two poisonous snakes in front of him, nailing them to the ground and unable to move.
