As they approached, everyone's hearts began to get nervous.

If it weren't for the fact that it was too dark for the drone to take a clear picture, Nuan Nuan really wanted to send a drone to the front to reconnoiter the situation.

"Why do I feel uneasy?" After turning a corner, the turtle immortal said nervously.

Nuan Nuan said in a deep voice: "Try not to make a sound." ”

There was a large two-meter-high stone in front of it, and a foot below the stone was full of small holes from which water flowed.

How do you move this stone away in such a small underground passage? If the stones are forcibly removed, will it lead to a landslide?

Nuan Nuan was worried, and she didn't know what to do for a while.

"Cousin, why aren't you leaving?" Cute lowered her voice.

"We're in trouble, there's a big rock blocking our way." Nuan Nuan said helplessly.

Walking to the big stone, Nuan Nuan carefully observed, gently tapping the stone with her hand, the stone came with a dull sound, accompanied by a slight vibration.

In the end, Nuan Nuan was sure that this was not a big rock at all, but a door.

Nuan Nuan said to everyone: "This is a door, and the other end of the door is sure that it is the water prison." ”

"So what do we do? Nuan Nuan quickly figured it out. Prawn lowered his voice and said anxiously.

"Let me try it."

The turtle immortal pulled open the frame, and was about to hit the stone door with his shell, but was held down by Nuan Nuan.

What are you kidding, if you really hit it, don't break the stone door and attract the dark spirit warriors, who knows if there will be guards in this underground dungeon?

Nuan Nuan estimated in her heart that there was a high probability that there were mutant warriors guarding this underground.

The turtle immortal shook his head, his eyes full of questions.

"Don't be impulsive, there are likely to be guards at the other end of the stone gate." Nuan Nuan lowered her voice.

The truth is really as Nuan Nuan guessed, there are several mutant warriors with water attributes at the end of the stone gate, and the sound made by Nuan Nuan when she gently knocked on the stone door just now has already made them hear.

They looked this way, and the warm tapping stopped.

The leader of the mutant warrior is called Xi Yan, it has a pair of horns on its head, and it is three meters tall.

It stared in the direction of the stone gate, its heart was full of doubts, it had been guarding Xue Yan here for a day, and it had never heard a sound from the stone gate.

It knows the importance of this mermaid and can't afford to slip up.

It motioned to a few warriors around it, and then it took a long steel fork and walked towards the stone gate, followed by four warriors behind it.

When he arrived next to the stone gate, Xi Yan pricked up his ears and listened, but he didn't hear a sound.

A soldier behind Xi Yan spoke, "Captain Xi Yan, maybe it's the knock caused by the sound of the water." ”

"No way, my ears are very sensitive, there must be something abnormal." Xiyan said.

Due to the heavy stone gate, the voices of both sides could not reach the ears of both sides.

At the end of the stone gate, Nuan Nuan stretched out her hand again, ready to knock on the stone door, and there was a knock sound from the stone door.

Nuan Nuan was so frightened that she quickly retracted her hand, Silly Meng and the Turtle Immortal were leaning against the stone door, and after hearing the voice, Dumb Meng opened her mouth and was about to shout out.

Nuan Nuan quickly covered Silly Meng's mouth, and Silly Meng also realized it, and swallowed back the shout that came to her mouth.

"That's the same sound just now, is someone really coming?" Xi Yan at the other end of the stone gate was full of questions. The sound of the stone gate just now was the same as the sound of him knocking, which meant that there was someone at the end of the stone gate.

"Captain, this water is as strong as gold, and it is impossible for anyone to come down the underground river." A warrior with a big head and a crooked neck behind him said with a smile.

"The underground river is such a small space, no one will come by mistake." Another warrior followed.

"Could it be that there are fish in this underground river?" Xi Yan thought about it and thought it was very possible.

"Perhaps, this underground river leads to the lake outside the castle, and maybe some fish are swimming against the water." The crooked-necked warrior explained.

It is Xiyan's right-hand man and often helps Xiyan with advice. This time, the errand of guarding Queen Xue Yan was won by it. As long as there are no problems with the Snow Queen, then they are a great achievement.

Nuan Nuan hinted to Silly Meng not to make a sound, and then took her hand away.

Nuan Nuan suddenly thought of an idea in her heart, if I knocked on the stone door again, what would be the reaction of the people over there? Will they open the door and come and check?

Then Nuan Nuan stretched out her hand and knocked the stone door.

Xi Yan thought that no one could come here anyway, and then he was about to turn around and walk back.

There was another sound from the stone gate, the sound was louder than just now, Xi Yan held the steel fork and turned his head violently.

"It seems that this fish wants to come over, listen to the sound, this fish should be very big." Xi Yan said with a smile.

"Why don't we open the door and catch the fish, and we'll be able to pass the time here grilling the fish." The crooked neck warrior said flatteringly.

"Then what are you doing nonsense, hurry up and open the stone gate, and eat grilled fish at noon today." Xi Yan said excitedly.

Nuan Nuan on the side of the stone gate took out the water beads again, and then led everyone into the water, waiting for the movement at the other end of the stone gate.

Queen Xue Yan looked in the direction of the stone gate, she was fifty meters away from the stone gate, she heard those warriors say that there were fish coming, she thought to herself: Could it be that my people have come to save me? That seems unlikely.

Because this place was too far away from the merfolk hometown, it was impossible for someone from the tribe to come to her rescue so soon.

Queen Xue Yan looked curiously in the direction of the stone gate, whether anyone came to save her or not, at least her curiosity was aroused.

The Crooked Neck Warrior took out the key and opened a box next to the stone door, revealing the handle inside.

Then it stretched out its hand and pulled the handle slightly, and the stone door creaked and slowly rose.

In order to prevent Queen Xue Yan from escaping, the Dark Spirit Clan has taken precautions in place, locking people in cages, and sending people to guard them.

The stone gate was opened, and Xi Yan took out the luminous beads and shone on the water outside the stone gate.

This luminous pearl was given to him by Leng Chaoge's subordinates, after breaking through the city of the mermaid clan, Leng Chaoge and Seqing's subordinates seized a lot of these beads, and yesterday they came here to help guard the water prison and sent several luminous beads to the guards here.

"Where's the big fish?" Xi Yan took the luminous bead and said according to the water.

Then it took a steel fork and stabbed it into the water, stabbing the turtle immortal who was hiding under the water.

"Hey, how can there be such a big stone in this water?" Xi Yan let out a sound of surprise.
