When Qin Xiaoxi said this, her face turned pale.

"When I went down to change my clothes yesterday..."

"Did you see a rat?"Jiang Yun suddenly interrupted. In the next second, he was hit by Qin Xiaoxi.

"What rat? Don't interrupt me. At that time, I heard something knocking on the outside of the cabin. The sound lasted for a while. Later, I thought we might have bumped into a fish, so I didn't take it seriously," Qin Xiaoxi said with a serious expression.

"Did you hear wrong?"Jiang Yun looked at Qin Xiaoxi strangely.

"That's impossible. I even went closer to hear it. But when I got closer, the sound disappeared without a trace." Qin Xiaoxi seemed to believe that she had heard something.

Because now when she thought about it unless it was a very big fish, it would not be able to keep making that sound even if it hit their bed very hard.

"Were you dazed at that time?" Jiang Yun seemed to become serious when he heard this.

Qin Xiaoxi just shook her head.

"No... I'm sure."

The two of them were silent for a while. Although it sounded like they had just hit a big fish. But this was the Sea of the Northern Region after all. It would be terrible if something special really happened. Jiang Yun thought to himself. Hence, he hurriedly walked towards the cabin.

"Wait for me on the deck. I'll go down and see what's going on."

Qin Xiaoxi nodded.

At this moment, a gust of cold wind blew past. Qin Xiaoxi could not help but shiver. It was so cold. She felt that she should put on those coats as well.

Jiang Yun hurriedly went to the secret door leading to the cabin below. He found a suitable spot and slowly climbed down the straight ladder.

As Jiang Yun went down.

The knocking sound also rang out.

At first, Jiang Yun didn't think much of it. But in the next second, he felt that something was wrong. His feet stepped on the wooden ladder, and no matter how he stepped on it, that was a creaking sound. How could there be a sound like knocking on the door?

Knock, knock, knock...'

The strange sound came again, and it seemed to be around him.

Was this the strange sound that Qin Xiaoxi had heard?

What on Earth was this? How could it make such a sound?

Jiang Yun felt very strange. He quickly flicked two fingers, and weak spiritual energy shot into the air, illuminating every corner of the lower cabin.

And with Jiang Yun's arrival.

The original knocking sound seemed to become weaker and weaker. They seemed to know Jiang Yun's arrival, and the strange sound gradually disappeared.

It was really strange.

Could it be that the sound was not in the sea, but in this cabin?

Thinking of this, Jiang Yun hurriedly let the light formed by the gathering of spiritual power become even brighter.

Jiang Yun looked around. Actually, he rarely came to the cabin below, except for this morning and the first day on the ship. He had almost never gone down to the bottom cabin because most of this floor was below the sea surface, and it was very humid. Therefore, most of the time, he and Qin Xiaoxi stayed on the upper floor.

The lower cabin was a little bigger than the upper floor. There was nothing here. Except a few wooden pillars with a little mold and a few piles of hay, there was nothing else.

Could it really be a rat?

Jiang Yun quickly began to turn the hay.

But there was no rat. There wasn't even a hole in the cabin, let alone the existence of rats.

This was strange. Jiang Yun couldn't figure it out.

Could it be that while he was still in the cabin, countless waves of fish had crashed into the outside of the ship?

Jiang Yun felt that this was very strange, but he still wasn't convinced. Therefore, Jiang Yun slowed down his pace and came to the wooden wall of the cabin. Although there were two layers of wooden walls on the outside of a ship like this, they were all put together without leaving any gaps in the middle.

Therefore, Jiang Yun had already eliminated the rats and the like between the layers.

Jiang Yun gently placed his palm on the wooden wall.

However, he did not sense anything wrong.

Then, he quickly stretched out his finger and made a hand gesture to knock on the door. He gently knocked twice on the wooden wall.

Knock, knock...

When he heard the sound, he was shocked.

Wasn't this exactly the same as the sound he heard just now? At this moment, he thought of a very uncomfortable scene. Could it be that, in the deep sea beyond the wall, there was also someone knocking on the wall?

F * CK, that was too strange. Jiang Yun couldn't help but feel shocked. In his mind, he had already started to imagine a person in the water knocking on their boat. That imagination gave him goose bumps.

However, after a while, he dispelled this thought. Even if it was an extremely powerful cultivator, it was impossible for them to stay underwater for such a long time to breathe.

Jiang Yun hurriedly moved his ears closer to the wall.

Knock, Knock, knock...

Rumble. Just as he moved his ears closer to hear what the sound was, the knocking sound suddenly came again, and this time, it seemed to be even more intense than before.

Knock, knock, knock...

"What is it?"Jiang Yun immediately frowned. He hated this kind of thing the most. In the meantime, he hurriedly pressed his palm on the wall, and a surge of spirit energy instantly surged on his wrist, the spiritual power condensed in Jiang Yun's hand for a while, and then instantly flowed out of his palm.

After the white spiritual power hit the wall, it quickly spread out like lightning, and finally covered to every corner of the cabin.

At the same time, the sound of the mysterious knocking on the wooden boat also disappeared.

Although it disappeared, Jiang Yun still didn't understand what the sound was coming from.

"Jiang Yun! Jiang Yun!"

While he was thinking hard, Qin Xiaoxi's call came from the deck. It seemed that Qin Xiaoxi had found something new.
