Fortunately, the second-in-command was a coward who feared death, and unexpectedly, the map of Black Wind Stronghold he described was actually accurate. Relying on the sentry posts mentioned by the second-in-command, Jiang Wanwan and Qi Zhao avoided many patrolling bandits and sentries.

After circling most of the mountain stronghold, Jiang Wanwan and Qi Zhao finally arrived at the place where Black Wind Stronghold imprisoned the young and strong.

This is a large prison built by Black Wind Stronghold. The prison gate is a heavy iron gate, and there are guards on both sides of the gate, about six people guarding it.

The prison walls were very high, making the entire prison completely airtight.

Moreover, as the second-in-command just mentioned, a patrol team would patrol the area around the prison every fifteen minutes. The defenses were extremely tight.

After discussing it, Jiang Wanwan and Qi Zhao decided to deal with the guards on both sides first. Qi Zhao would sneak into the prison to find Deputy General Liu, while Jiang Wanwan would meet them at the gate to prevent them from being wiped out by the bandits when the patrol team arrived.

After waiting for about fifteen minutes, a patrol team indeed passed by the prison.

After the patrol team had gone a little further away, Jiang Wanwan and Qi Zhao hid in the shadows and slowly approached the prison.

Jiang Wanwan followed suit, sneaking close to the guards from the base of the wall, and then, when they weren't looking, sprinkled a handful of powder on them.

Before the six bandits could react, they had already fallen to the ground.

Qi Zhao and Jiang Wanwan quickly stepped forward and nimbly searched the six guards for the prison key. A short while later, they found a key on one of the bandits.

Qi Zhao took the key and successfully opened the prison door.

Jiang Wanwan said to Qi Zhao, "Qi Zhao, move quickly, we only have fifteen minutes. If you hear the whistle, you need to come out as soon as possible."

She pointed to the whistle hanging around her neck.

"Okay, I understand. Be careful in everything you do out there. If things don't go well, don't worry about us. You can go now," Qi Zhao instructed.

After saying that, Qi Zhao dared not waste any more time, turned around and rushed into the dungeon.

Jiang Wanwan squatted at the doorway, holding the dagger that could cut through iron like mud in her hand, watching her surroundings warily, ready to send a signal to Qi Zhao immediately if anything seemed amiss.

Time ticked by, and Jiang Wanwan grew increasingly anxious, peeking into the dungeon every now and then. She muttered to herself, "Oh dear, almost a quarter of an hour has passed, why hasn't Qi Zhao come out yet? Could it be that he can't find Deputy General Liu? Or perhaps there are bandits in the dungeon too?"

She was so anxious she was pacing around in circles.

Jiang Wanwan paced anxiously in front of the prison gate, grabbing the binoculars hanging around her neck to check the surroundings.

She sewed a cloth cover for the binoculars so that even if others saw it, they wouldn't know what was hanging around her neck.

Because some braziers were lit around the stronghold for illumination, Jiang Wanwan was able to use a telescope to observe the situation of the stronghold.

Through the binoculars, a patrol team could be seen heading towards the prison.

Jiang Wanwan picked up the whistle, just about to give Qi Zhao a signal, when suddenly a lot of people ran out of the prison.

These were all young and middle-aged men, their faces filthy and covered in dust. Moreover, their clothes were so covered in yellow mud that their original colors were unrecognizable, making them all look extremely disheveled.
