Too many female prisoners, a special forces soldier transmigrates and marries wildly.

Using the last rays of daylight outside the door, they were able to see the interior of the stone fortress.

There is no gold or silver here, no ledgers.

There were only rows of rusted iron cages and scattered bones on the ground.

The iron cage bars were frighteningly thick, covered with deep scratches, like the frantic struggle of some wild beast before its death. Most of the bones were incomplete, some even twisted in a contorted position, as if they had endured immense suffering before dying.

"This is... a beast cage?" Di Ting asked, trembling. "What kind of ferocious beasts are they keeping here?"

"It wasn't a ferocious beast." Su Xuanji's voice trembled slightly as she crouched down and picked up a small piece of tattered cloth from a pile of bones. The cloth was of fine quality, in the style of an official's robe, but the color had faded completely.

She then pointed to a heavy stone block in the corner, chained with indistinct writing.

Lin Feng approached and, in the dim light, made out the line of words:

"In the seventh year of Tianyou, the mining supervisor Li Chong was ordered to guard Yue'er Spring. Anyone who secretly spyes on the mine veins will be executed. Anyone who dares to discuss mining will be executed. Anyone who…"

The writing at the end is blurry and illegible.

But it is enough.

Lin Feng slowly straightened up, surveying the stone fortress filled with death and despair. He understood. This wasn't a silver mine at all, or rather, the silver mine was merely a disguise.

This is an underground prison where the former imperial family secretly imprisoned serious criminals and conducted some kind of forbidden experiments!

The so-called "high-grade silver mine" may just be a pretext for the prisoners to toil day and night. And the so-called "man-made disaster" is probably the riot and destruction instigated by these prisoners, or guards, who were tortured to death, before their deaths.

"We need to get out of here as soon as possible," Lin Feng said in a deep voice, a strong sense of unease gripping his heart.

"What's here is far more dangerous than we imagined. Let's find the real entrance to the vault and leave immediately."

Before he finished speaking, a clear, metallic "click" sound suddenly came from above the mine outside the stone fortress.

That wasn't the sound of the wind.

It was as if... some huge, long-dormant mechanical device had been awakened by their intrusion.

Lin Feng suddenly rushed out of the stone fortress and looked up at the towering rock wall.

"Retreat!" Lin Feng roared, making a decisive decision. "Retreat back to the stone fortress! Quickly!"

With their rich experience, Di Ting and Suo Hun protected Su Xuanji from the left and right, respectively, while Lin Feng brought up the rear. With the Duan Yue Blade held horizontally in front of them, without hesitation, everyone set off at full speed.

"Click...click..." The dense sounds of machinery came from all directions, no longer from a single source. The entire mine pit, like a sleeping behemoth, was awakened and began to stretch its limbs.

They had just rushed into the stone fortress and barely managed to close the heavy iron door. Almost the instant the door closed, a rapid series of whooshing sounds filled the air!

"Thud thud thud!" Countless tiny, barbed short arrows were driven deep into the iron gate and outer wall, penetrating three inches into the stone! If they had been a moment later, they would have been turned into hedgehogs by now.

"It's a repeating crossbow! There's a repeating crossbow hidden in the wall!" Soul Locker leaned against the door, his face pale.

Lin Feng's mind raced. He suddenly looked inside the stone fortress, at the iron cage that locked the heavy stone block.

"Listen to the Earth!" Lin Feng shouted. "Come look at this stone pillar! Soul Locker, you and I will pry open these iron cages together and see if there's a passage underneath!"

"Yes!" The two were startled but remained calm and immediately sprang into action.

Di Ting rushed to the stone pillar, tapped on it carefully, and quickly exclaimed, "Guards! The stone pillar is hollow! There's airflow underneath! There's a passage down there!"

On the other side, Lin Feng and Suo Hun used the Broken Mountain Blade and tools to forcibly pry open the bottom of an iron cage. The rusted iron plate was lifted, revealing a dark hole underneath, and a stronger wind, mixed with the smell of decay and minerals, blew up.

"There's a way!" Soul Locker was overjoyed.

"Jump!" Lin Feng decided immediately. "One by one, I'll cover the rear!"

Without hesitation, Su Xuanji was the first to jump into the cave. Di Ting and Suo Hun followed closely behind.

Lin Feng leaped into the cave like a hawk in the air!

Inside the cave, it was pitch black, and the only sound was the heavy breathing of the group.

"Let's go." Lin Feng's voice rang out in the darkness, chillingly calm. "This is probably where the true entrance to Moon Spring is. Stay close to me, don't fall behind."

After walking for about the time it takes for an incense stick to burn, a faint ray of light appeared ahead.

Lin Feng raised his hand to signal everyone to stop, then held his breath and crept forward. At the end of the tunnel was a half-open, heavy stone door. From the crack in the door, not only light emanated, but also an intense, almost overwhelming, scent of silver.

It wasn't the fishy smell of slag, nor the coldness of metal, but the somber aura emanating from pure, piled-up silver.

Lin Feng used the tip of his Broken Mountain Blade to push open the stone door extremely slowly.

The sight behind the door left even the general, who had crawled out of a mountain of corpses and a sea of ​​blood, speechless for a moment.

This is not some kind of hell, but a huge natural cave. In the center of the cave, there are no jewels, only piles of silver ingots.

The official minting patterns and the standard "Tianyou Tongbao" mark—each ingot was stacked neatly, like soldiers awaiting inspection. A rough estimate suggests that the silver here is enough to cover the expenses of the entire northern army of the Great Yan for ten years!

Lin Feng's gaze passed over Silver Mountain and looked towards the end of the cave. There, there was a small stone platform, on which lay a weathered account book and an exquisitely crafted, water-powered timekeeping device.

He stepped forward and picked up the ledger. The pages were fragile, but the writing was still clear.

"In the first year of Tianyou, the mining supervisor Li Chong received a secret decree: the Yue'erquan silver mine is actually a 'silver vault.' The silver produced will not enter the national treasury, nor will it be used to mint coins. It will be used exclusively for... 'to suppress the dragon vein and secure the state.'"

Lin Feng's mind raced as he read this. Suppress the dragon vein? Secure the nation? With silver?

He suddenly looked around at the rock walls. He then realized that the cave walls were not naturally formed, but rather artificially polished, covered with dense patterns resembling feng shui maps. And the silver mountain happened to be pressing down on several key points of those patterns.

"This isn't a silver mine," Lin Feng said hoarsely. "This is a 'array eye' made of silver. The previous dynasty's royal family used this silver to suppress some kind of underground... geological hazard? Or perhaps they were superstitious and believed it would ensure the eternal stability of their dynasty."

"So, the 'man-made disaster' is neither a riot nor an experiment," Su Xuanji replied, her face pale.

"It was Li Chong, the mine supervisor, who carried out a secret decree. With the previous dynasty on the verge of collapse, he sealed the last batch of silver here, cutting off all contact with the outside world, making himself and all the craftsmen the burial victims of this 'silver array.' He wanted to use this method to complete the final 'strengthening of the state.'"
