There are not only beaches but also reefs on the coast.

This stretch of coast is full of reefs, covered with many shells, but this kind of place is not popular.

Because these shells are sharp and most of them have no flesh, even if they have flesh, you have to be very careful when prying them off. If you get cut, it would be dangerous.

"It's indeed here, and it seems to be underground." Long Aotian was not too sure and could only give a rough range.

"Underground, that's the seabed?" Lu Yunxi looked at the reefs, glanced at the sea surface, and fell into deep thought.

Even if he is really a big shot in the world of immortal cultivation who has survived to this day...but he lives at the bottom of the sea, so he can't be a human, right?

The man and the beast discussed it and finally decided that Lu Yunxi would go to the sea to look for it, while Long Aotian would stay above to look for it.

Luckily, this is a small island. If I were on another continent, I would be swept away if I jumped in. The small island only has a few protruding corners that can be teleported, and I won't be sent away if I go to the sea from other coasts.

She put a protective shield on herself and went into the sea.

There are many reefs in the sea, beautiful corals growing freely, and occasionally fish swim by.

Following Long Aotian's advice, Lu Yunxi tried to find creatures with special appearances, or eggs or something like that.

However, there were so many things in the sea that she found them all strange and rare. Furthermore, they couldn't be put into her space and had to be carried around with her. Long Aotian had said that her space couldn't hold living things. It was fine for a short time, but over a long period of time, they wouldn't be able to survive.

It wasn't long before she had scooped up a whole bunch of stuff.

However, Long Aotian shook his head. The sounds made by these creatures were completely different from what he heard.

In this way, time passed as they salvaged the items.

At the end of the day, they only harvested a large amount of food.

Lu Yunxi lit the fire and looked at the pile of seafood. She was too lazy to cook anything else, so she just added water and boiled it in a pot. Then she cut it into pieces and ate it with soy sauce.

The man and the beast finished their food without tasting it, and began to reflect.

"Could there be some mechanism on the reef?" Lu Yunxi suspected. "Maybe someone really has dug a tunnel there?"

After all, in the world of cultivating immortals, there are all kinds of methods. She doesn't believe that there is no very powerful method of digging tunnels!

Long Aotian also tried to recall: "What on earth was that sound coming from?"

When the man and the beast were each in deep thought.

"Here it comes! That voice is coming again!" Long Aotian suddenly stood up and walked back and forth anxiously.

Its ears moved, and it suddenly stopped at a certain position: "It's right below."

Lu Yunxi looked at that location and immediately understood.

She took out tools such as shovels and spades she had made herself from her backpack and started to act.

Long Aotian had no way to dig the soil, so he could only occasionally spray a little fire downwards, but he didn't dare to use too much force, for fear of accidentally killing the owner of the voice.

The man and the beast were somewhat restrained.

Fortunately, Lu Yunxi didn't dig for long before he suddenly dug out a hole.

She dug away the mud and sand on top, revealing a big hole in the middle.

"This is?"?
