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

Xie Wanqing shook her head: "'Qianyuan' operates in secrecy, and its forces are scattered. Last night's attack was already extremely risky. General, you must be extra careful of the hidden people in the city who are working for Feng Kun."

Feng Kun's hidden forces... Lin Feng's heart sank. Although Liu Neng and the other "Listening Wind Guards" had been eliminated, it was hard to guarantee that there weren't any survivors or even deeper pawns.

"I understand. Withdraw most of the guards from the west courtyard, leaving only two at the gate. Take good care of yourself." Lin Feng finished speaking and turned to leave the room.

Back in his study, he immediately summoned Han Tao, handed him the map of the earth's veins, and ordered him to readjust the defensive layout outside the city according to the map, avoiding areas with unstable earth energy and making use of favorable terrain.

After finishing these tasks, he pushed open the door to the inner courtyard. Yun Li was still awake, sewing a small baby garment by lamplight. Seeing him return covered in sweat, she quickly got up.

"Husband, why are you wet? Quickly change your clothes." She brought over a dry robe.

Lin Feng changed out of his wet clothes, took her hand, and looked at her gentle profile under the lamplight. He suddenly said, "Yun Li, if one day, your father... His Highness Prince Jing's affairs require you to make certain choices or face certain dangers, what will you do?"

Yun Li paused in her needlework, looked up at him, a hint of confusion flashing in her eyes before turning into determination: "Husband, my father is Prince Jing, but I am also your wife, the wife of the garrison commander of this Iron Wall City. If that day ever comes, I will listen to my husband. Wherever my husband is, that will be my home, my choice."

A warm feeling welled up in Lin Feng's heart, and he gently pulled her into his arms. "Don't worry, I'm here."

Inside the largest cowhide tent in the Di Rong camp outside the city, Asuda was facing a simple map of the northern border, having a private discussion with Mr. Jia.

On the map, the location of Ironwall City was heavily circled.

"Your Majesty, now that 'Earth Listener' has appeared and intervened, this matter has become even more troublesome," Mr. Jia said, stroking his beard.

"Yesterday's ground collapse is clear proof. With their secret assistance to Lin Feng, his attack on the Iron Wall will surely result in huge losses."

Asda's face darkened: "Are we just going to give up like this? I've mobilized so many troops; if we retreat in disgrace, what face will we have left?"

"No." A sly glint flashed in Mr. Jia's eyes.

"The interior of 'Dark Abyss' is not monolithic. General Feng has secretly contacted a person codenamed 'Mountain Ghost,' who was a former employee of 'Dark Abyss' who was in charge of some of the mine files. Dissatisfied with Prince Jing's treatment, he has already secretly joined the cause. However, this person is very well hidden and can only be awakened with a specific token and code."

"Lin Feng will surely try to seek help from Shuofeng. Why don't we turn the tables and ambush them on their inevitable route? If we can severely damage or even annihilate their reinforcements, then Iron Wall City will truly become an isolated city, and Lin Feng, besieged from both inside and outside, will collapse without a fight!"

A fierce glint flashed in Asuda's eyes: "A good plan! We'll do as you say, sir!"

In the afternoon, the sky remained overcast.

Lin Feng was patrolling the city wall when his personal guards reported that the fast horse sent to Shuofeng to request reinforcements had met with Commander Zhao Polu. The commander replied that the 5,000 reinforcements had been assembled and were led by his deputy, Zhou Ming, and would depart in three days.

"Commander, the reinforcements from Deputy General Zhou won't arrive for at least five or six days. Can we hold out until then?" Han Tao asked worriedly.

"We must hold on." Lin Feng said decisively. "There are ambushes on the way to reinforcements, so we must hold them off and not let them lose everything."

"yes!"

As evening approached, Yan Qing rushed over to report.

"Guards, there's been unusual activity at the Di Rong camp outside the city. About three hundred cavalrymen have left the camp and are galloping southeast. Judging from their attire and banners, they are the elite 'Black Wolf Guard' of the Black Wolf tribe. They... seem to be carrying digging tools."

"The tea stall diagonally opposite 'Liu's Leather Shop' in the city has a new employee these past two days, a completely unfamiliar face. Also, although Hou San of the East Gate Tavern has been arrested, he has a distant nephew who suddenly came from inside the pass to seek refuge the day before yesterday."

Is it another group of people from Feng Kun starting up?

"Keep a close eye on these two. Don't alert them," Lin Feng ordered in a deep voice. "Also, double the manpower to keep a close watch on the warehouse, the well, and several potential danger zones within the city marked on the ley lines."

"yes!"

In the west wing room, Xie Wanqing was not asleep.

She put on her coat, got up, walked to the window, and looked towards the main courtyard of the garrison. The lights there had long been extinguished, with only the night lanterns under the eaves casting a dim yellow glow in the cold wind.

Suddenly, her ears twitched slightly.

A very faint, persistent sound, like the gurgling of water or the rustling of a groundhog digging in the soil, came from underground and from the cracks in the walls.

If it weren't for the fact that it was late at night and she had exceptionally sharp hearing since childhood, she would have hardly noticed it.

What is that sound? She frowned and listened carefully.

The sound seemed to be coming from... the back of the west courtyard, in a corner near the courtyard wall? There were several woodsheds used for storing miscellaneous items and an abandoned old well there.

The sound of water? No, it's deeper, more muffled. Like... digging? Or the echo of water flowing in some kind of cavity?

She could no longer sit still and gently pushed open the door.

The courtyard was empty, with only two guards leaning against the wall by the gate, feigning sleep wrapped in fur coats. She tiptoed quietly toward the woodshed in the backyard.

The woodshed was dilapidated, and the door was ajar. The eerie rustling sound seemed clearer. She held her breath, leaned closer to the crack in the door, and peered inside.

The woodshed was cluttered and dimly lit. The sound seemed to be coming from the innermost part of the woodshed, near the sealed old well. By the pale moonlight filtering through the window, she could vaguely see that the stone slab sealing the old well seemed... to have been moved a crack?

Someone disturbed this abandoned well! She tried to get closer to take a closer look, but her foot stepped on a dry branch, making a soft "crack" sound.

"Who?!" A deep, sharp shout suddenly came from the shadows of the woodshed! A dark figure leaped up from the well like a ghost, a flash of cold light in his hand, and lunged straight at Xie Wanqing's face!
