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

Lin Feng walked to the hydraulic timer. The device had stopped, the pointer fixed on a single mark. He calculated the time; from the first year of Tianyou to now, it had been exactly…

The suppressive power of the "Silver Array" is almost exhausted.

Or rather, some underground force is about to break free from its constraints.

"We need to get this silver out of here," Lin Feng decided immediately. "That's exactly what Ironwall City needs right now."

"How are we going to transport it?" Di Ting asked, looking at the mountain of silver ingots. "With so much silver, it would take hundreds of carts to move it. And how are we going to get it out of that sealed-off mine?"

Lin Feng looked towards the top of the cave. There, he could faintly hear the sound of flowing water.

"Moonlight Spring," he said in a deep voice. "Since it's called Moonlight Spring, there must be an underground river below. We don't need to go back the way we came. We can put the silver into leather bags and let it float down the underground river. Di Ting, you go find the entrance to the underground river. Suo Hun, you come with me and put these silver ingots into bags."

"Miss Su, you stay here and check the accounts. See if there are any other clues. Especially... about how to 'restart' or 'safely transfer' this silver array. If this silver array is really maintaining something, we have to be prepared to face the consequences if we empty it out."

The group immediately divided up the tasks. Inside the cave, only the heavy footsteps of carrying silver ingots and heavy breathing could be heard.

"Guards, the entrance to the underground river has been found!" The voice of the Earth Listener came from the deepest part of the cave.

Lin Feng put down the silver ingot and strode away. In the shadow of the cave wall, a half-submerged cave entrance was revealed, with water flowing silently into it, its depths unfathomable.

"The water is calm and flows outwards," Di Ting added, "but the situation inside is unclear; there may be hidden reefs, or it may lead to a dead end."

"Let's take a gamble." Lin Feng didn't hesitate. "Soul Locker, you and Earth Listener are in charge of building the raft. Put the silver ingots into the leather bag and secure it to the raft. Miss Su, you continue to check the accounts and look for any records about the exit of the underground river."

Everyone immediately sprang into action. Soul Locker and Earth Listener used their ropes, dismantled wooden frames, and scattered dry wood from the cave to quickly tie together several makeshift rafts. Lin Feng and Su Xuanji, meanwhile, focused on reviewing the remaining account books.

"The ledger records that the Moon Spring Silver Vault, besides suppressing the earth's veins, was also the secret treasury of the previous dynasty's royal family." Su Xuanji read quickly, her tone calm. "The underground river is a pre-designed transportation route, and the exit should be at the 'Blackwater Ravine,' over a hundred miles away. But..."

"But what?" Lin Feng stuffed a silver ingot into the leather bag and tied it tightly.

"But the records say that the underground river has a 'sluice gate,' which can only be opened with a royal token. Without the token, forcing your way in will result in being swept away by the raging current." Su Xuanji raised her head, her brows furrowed. "We don't have the token."

Lin Feng walked to the entrance of the underground river, looking at the dark, murky water. "The token isn't important. The previous dynasty is gone, and the sluice gate's mechanism is probably rusted shut. If it can't be opened, we'll forge our own way."

He checked the rafts' bindings and ordered, "Di Ting, you take two rafts to scout ahead, slowly lowering the ropes. If there's any danger, come back immediately. Suo Hun and I will cover the rear, and Miss Su will stay in the middle."

"yes!"

The first raft was pushed into the dark river. Di Ting and a personal guard, holding torches, carefully propelled the raft into the darkness. The rope slowly stretched until it was fully taut, a process that took about the time it takes to brew a cup of tea.

"Defend! There's a sluice gate ahead! The water flow is blocked!" The voice from the ground echoed through the darkness.

"Gate status?" Lin Feng asked.

"It's rusted to death! Not moving an inch! But... there seems to be a spillway above the gate, only big enough for one person at a time!"

"Can we cross on the raft?"

"No, it's too narrow, and the edges are covered in sharp iron spikes!"

Lin Feng's heart sank. If the silver ingots couldn't be transported out, all his hard work would be in vain.

"Me and Soul Lock will figure out a way to open the gate."

"Guards, this is too dangerous!" Su Xuanji exclaimed urgently. "The underground river has a complex structure; forcibly disrupting it could trigger a landslide and bury us all here!"

"Let's take a gamble." Lin Feng had already drawn his Broken Mountain Blade. "Soul Lock, come with me. We'll pry it open with our blades!"

The two jumped onto the raft and approached the massive, rusty iron gate. The water seeping from the cracks where the gate met the rock wall had a reddish-brown hue.

"Locking Soul, you hold the raft, I'll pry open the gap!" Lin Feng inserted the Broken Mountain Blade into the joint between the gate and the rock wall, and pulled the handle with all his might.

"Crack—" A metallic sound rang out. The sharpness and hardness of the Broken Mountain Blade were beyond imagination; it actually managed to pry open a crack in the heavy gate!

"It works!" Soul Lock was overjoyed and drew his sword to help.

Together, the two men pried it open inch by inch. Water began to gush out of the gap at an accelerated rate, forming a whirlpool. The raft rocked violently.

"Give it your all!" Lin Feng roared, veins bulging on his forehead.

With a muffled thud, the sluice gate was pried open, creating a gap large enough for the raft to pass through! But the immense water pressure also rushed in, instantly capsizing the raft!

"Hold on tight!" Lin Feng grabbed Suo Hun's wrist in the rushing water, and the two clung tightly to the protrusions on the rock wall, letting the icy water hit their bodies.

Once the current slowed down a bit, they scrambled ashore in a disheveled state and returned to the cave.

"Guards! Are you alright?" Su Xuanji and Di Ting waited anxiously.

"It's alright." Lin Feng wiped the water off his face and pointed towards the sluice gate. "The gap is big enough for the raft to pass. But the silver ingots... can't get through. The edge of the sluice gate gap is too sharp; a leather bag would tear with just a graze."

The crowd looked at the heavy pile of silver ingots, then at the narrow and dangerous underground river, and fell silent for a moment.

"We'll ship them in batches," Lin Feng decided. "Each person will ship as much as they can each time. The rest..."

He glanced at the mountain of silver, a flicker of reluctance crossing his eyes, but it quickly turned into resolve: "The rest, seal it up on the spot. We can't leave it for future generations, nor can we let it continue to be piled up here. Miss Su, remember the exact location, and come back to retrieve it when you have the chance."

This was the most realistic choice. Between survival and greed, Lin Feng chose the former.

The group immediately took action, breaking the silver ingots into smaller pieces, wrapping them in their clothes, carrying them on their backs, and beginning to pass through the narrow, sharp flood discharge channel and the gap in the sluice gate that had been forcibly pried open.
