The dark path ran in all directions. Xiao Hai was dressed in black and was shuttling back and forth like his own yard.

He must have investigated for a long time. Gu Pingyan was being pulled by the man in black, and his legs were moving fast. He was connected to every corner of the tunnel, but there was only one way out, so he couldn't let anyone find out that they were still investigating.

They made many turns and arrived at the depths of the tunnel. The mud and stone walls that were supposed to be thick were covered in moss now. A damp smell filled their noses, but they could hear a faint human voice.

Xiao Hai lit up a fire piston. Deep in the cave, there was only the tightly shut wall.

Gu Danyan felt for the wall with his hands and said in a low voice, "Is this what you found?"

"Yes, there are people locked in here, but we can't find the entrance." Xiao Hai took off his mask. In such a small space, it was hard to breathe while wearing a mask.

"There's the sound of water and the sound of wind." Gu Danyan pressed his body against the wall and lightly tapped the wall in front of him. It was solid, but it was thick enough.

Xiao Hai nodded seriously as well. At this moment, Duan Chengxuan had already brought along some generals from the water stronghold and left. Their only chance was to find the person who was being held here tonight.

"They must have known something and were imprisoned here. Moreover, if they are still alive, it is either useful or have a large number of people. It is not easy to get rid of them all." Gu Liuyan was also analyzing the situation. After a while, she seemed to have heard the voices coming from inside become clearer.

The man in black next to her tore her off the wall without saying a word. "She's too dirty."

"We're looking for something." Gu Danyan staggered a few steps back to the man in black, but was amused by his words, "There's actually such a cute one among the prince's subordinates?"

The man in black didn't say anything, he just stood on his tiptoes to hold his head down.

"Crack." The sound of the old gears closing together could be heard.

Before Gu Liu Yan could react, the black clothed man and Xiao Hai grabbed one of her shoulders and pulled her to the other side, pressing her back against the wall.

The stone tiles beneath his feet began to move slowly in four different directions, producing a loud and clear sound. The sound of the wind became even louder, and only the sound of voices could be heard, disappearing without a trace.

There was still about a man's height to go down. Teng Ting, who was clinging to the wall, seemed to have been strengthened, and Xiao Hai wanted Gu Daiyan to wait on top of it. However, she had already jumped down long ago, with the black-clothed men following closely behind his.

Gu Daiyan had just climbed to the bottom and pushed open a door from the small room, when he heard the man's exclamation: "Why is there a girl here!"

"Those beasts!"

Unexpectedly, this place was supported by the stone pillars, while on the right was a long path with no windows. Outside was the river bank, and when the river was in high tide, the water would definitely flow into the river bank.

"Miss, don't be afraid. Their evil deeds can't be concealed for long." The man tied to the nearest pillar had his lower body soaked in cold water, but his voice was still low.

At this time, the man in black and Xiao Hai had completely calmed down. Gu Pingyan had already jumped into the puddle, leaned on his chest and listened to his heartbeat for a while, then took out a bottle of medicine from his pocket and poured it into his mouth: "If you continue soaking in it for another day or two, your life will probably be over."

That person was shocked and Xiao Hai, who was behind him, exclaimed, "Tong Zhou!"

"Commander Xiao, why are you here!" In the water prison, the Tong Zhou was shocked as well. However, it pulled at the wound on its back, causing it to turn pale in pain.

"Don't be so excited, let's talk slowly if you have something to say." Gu Liuyan did not hesitate to cut off the clothes on his sleeve, wrapping all the herbs he brought with him in a cloth. He twisted them into a ball and lightly tapped on the wound on his back: "The wound is very new."

"Didn't you die already?!" Xiao Hai also walked forward and wanted to cut the chain, but the black clothed man stopped him. "Your Highness still needs to find other evidence."

The meaning of the man in black was naturally not to destroy the scene.

Gu Liuyan frowned. After simply helping him deal with his wounds, he crawled out of the puddle and came to the side of the stunned man in the corner. He looked at them one by one, and his frown deepened.

As she walked forward, the other men had already called out to her, "Miss, you can't!"

"The poison in their bodies is too strong. Even if they were to get close, they would be infected."

However, Gu Liuyan had already lifted the black cloth. The man in the corner hurriedly buried his face in his knees, while the other men wrapped in black cloth squeezed into the corner.

After checking his pulse, Gu Pingyan slowly stood up. He fed the insignificant antidote and painkilling medicine in his waist pouch to them and also gave them the candied fruits that he had brought with him.

"Those who are heartless will be punished a thousand times more painful than you." Her voice was soft, but the men in front of her still didn't dare to get close to her due to the terrible wounds on their bodies.

"This is?" The Tong Zhou ship looked at Gu Danyan in confusion.

"The principal wife of the prince, Crown Princess Jing of Navy Tide." Xiao Hai gripped his longsword tightly, his jaw clenched. He could even see a few familiar faces here. These were the soldiers he had previously trained with, but now they were trapped in this terrifying prison.

Most of them were poisoned. The generals who knew Xiao Hai were bare-chested and the wounds on their back were almost completely new. Yet, they were trapped in the water prison.

Gu Danyan walked back to Xiao Hai's side and couldn't help asking: "Just now you said he died, what did that mean?"

"The Tong Zhou was the third general of the Sunset Water Army to die." Xiao Hai said word by word.

Gu Danyan's heart sank as he looked at the Tong Zhou in disbelief.

Wait, didn't Duan Cheng Xuan say that he personally sent people to kill the third general? Why was he still here? Could it be that Duan Chengxuan let him live, or the Tong Zhou had thought of a way to escape, and the corpse of the three high-ranking officers sent to Sky Flame, who was the third one?

Looking at Xiao Hai's shocked expression, he obviously didn't know that Duan Chengxuan had personally sent someone to kill the third general to push this matter forward. She could only look at the black-clothed man and make a silent gesture with his eyes, causing all of her questions to be stuck in his throat.

"What about those soldiers?" Xiao Hai also asked Gu Danyan.

Gu Liuyan clenched his fists tightly. With a cold look in his eyes, he said, "They were all used to test the poison."
