As soon as he reached the bottom of the sea, Yang Li seemed to have made a discovery, he squatted down, looked at a place under the water, turned his back, and couldn't see the changes on his face.

Where he looked, there was something in the lake that obscured him, and it was impossible to see what he was looking at.

Mo Tian and Yu Fu also discovered Yang Li's abnormality and walked towards him, what they saw in their eyes, they looked at each other, and their faces showed surprise.

Lin Shan also stepped forward, and when he saw the scene in front of him, he was also quite surprised.

At the bottom of the lake, there is a rather large water hole, in which the stars are shining, and there is a large glittering place inside, and when you look closely, these glowing things are still trembling slightly in the water, and they seem to be living things.

"Yang Daoyou, what is this?" Mo Tian spoke, his face was a little happy, looking at Yang Li's serious expression, could it be that this is a precious thing?

Many years ago, after he went back, he also found some books to read and understand the things under the sea, but the situation in the sea, the people on the shore knew very little.

In addition, he has a lot of things to do, and the cultivation time is also urgent, so in the end, he still knows a little less, and he has no understanding of these shining things in front of him.

Looking at this scale, there are at least more than 300 or so shining points, if it is really a precious elixir under the sea, this trip to Tongtian Lake, even if the excavation of the cave is not successful, it is worth the trip.

"If I'm not mistaken, these are Haitian Xing, a small spirit insect under the sea, as far as I know, Haitian Xing mainly lives in the depths of the seabed, and it must be in a place where the water aura is more abundant, everyone see!" Yang Li walked into the hole, stretched out his hand to the bright spot, picked up a small bright spot with two fingers, and handed it to the three of them.

Sure enough, this is indeed a fat little worm, and it is still trembling slightly in Yang Li's hand, it is only the size of a soybean, and there is a blue fluorescent dot on its back, and the highlight seen is the hair on its back.

"Haitian Star, what is the purpose of this spirit worm?" Yu Fu asked, his expression was also a little urgent, since he survived in a place where water spiritual energy was abundant, it could be a precious thing.

"Haitian Star, its body does contain aura, but unfortunately, it does not contain much, which is equivalent to the Gathering Spirit Pill taken by a monk in the long-term cultivation period. Yang Li said lightly.

Hearing that it was just like the effect of the Gathering Spirit Pill, Mo Tian and Yu Fu showed disappointment on their faces, now that they were in the late stage of foundation building, such an elixir was almost insignificant to them.

"Under my sect, there are just two long-term cultivators, collect them back, but it also saves a lot of spirit stone fees, three Daoists, can you take some?" Yang Li took out a dim vial and began to pick up the Haitian Star Spirit Worm.

More than 300 Haitian Star Little Spirit Worms, if it is really like the effect of Gathering Spirit Pill, it is also a sum of thousands of spirit stones, and it is indeed a small fortune.

"Under the younger brother, there is also a disciple of the Yuan Cultivation Period, so it's not bad to take some back. Lin Shan's eyes flashed, and he also took out a small bottle from his arms, stepped forward, and also picked up some spirit insects.

Seeing that Lin Shan also made a move, Yang Li's face did not change in the slightest, and he still had a smile on his face, not caring at all.

Mo Tian and Yu Fu finally picked up more than a dozen sea and sky stars, and the things in the sea are relatively rare, and it is not bad to take them back for study.

He and Yang Li's movements were not slow, and the small flashes of light in the cave quickly disappeared.

Yang Li was the fastest, picking up at least two hundred small insects, and Lin Shan also had about a hundred.

After picking up the sea and sky star, Mo Tian took the lead, he took out a water-blue bead from his arms and held it high above his head.

The beads glow with a deep blue light in the water, and the range in the water within three zhang is clearly visible above the ground.

The wonderful thing is that as soon as he appeared, there was no need to open the aura cover, and the sea water on both sides of Mo Tian automatically separated, just enough space for him to walk.

"Avoid water droplets?" Yu Fu saw and exclaimed first.

This thing is definitely a precious thing, with this thing, you can open the aura cover without spending aura, and it is as flexible as flat ground in the water, but this bead is not big to avoid water, and only allows one person.

"I'm ashamed, this bead is too small, and there is not much space to avoid water, so it can't shelter the three Taoist friends. Mo Tian said ashamed, but with a smile on his face, he was quite complacent.

After a while, he sighed in his heart, this water-repellent bead was actually obtained in this Tongtian Lake more than 20 years ago, and it still existed in that cave, but he couldn't take it out, and when the four of them found it, it couldn't be his alone.

Although I don't like it in my heart, I think that I can't open this cave by myself, even if I can't get my hands on a good treasure, it's a dream.

He packed up his mood and took the lead to rush to the seabed, the current at the bottom of the sea was very strong, and many scenes had changed in the past twenty years, he covered his head for a long time, and from time to time he searched in the raised mountains and concave valleys in the lake, but still could not find the location of the cave in his impression.

Ahead was a towering raised mountain, blocking Mo Tian's way.

"Worried!" Mo Tian, who was traveling, was about to bypass the mountain in the lake, when his expression suddenly changed, and he let out an exclamation, and his figure flashed backwards at the same time.

As soon as his words fell, the hill in front of him suddenly shook violently, the water flow accelerated, and the hill collapsed in an instant, and the mud in the sea suddenly filled the surroundings of the four people, and the vision began to blur.

"Shhh...... Woo ......" A sharp roar sounded at the same time, very close, Lin Shan's eardrums were a little painful, his heart sank, his body did not stop, and he quickly retreated.

In his senses, the hill shook and was moving towards them step by step.

This hill is nearly twenty zhang high, this movement, in the water stirred up a strong air current, towards them, although the air flow is strong, but the four of them are not slow, quickly avoid.

The vision became blurred in the muddy water, but the people present were all foundation building monks, so they were close, and after a lot of mud fell on the hill, they could still vaguely see what was in front of them.

Lin Shan gasped, this was actually a huge sea beast, compared to the four of them, they were like ants against elephants.

The fur was pitch black, and four giant feet lay together at the bottom of the sea, their backs bulging high, and a long, huge head sticking out in front of them, and its open mouth was full of sharp, small teeth.

It looks like an enlarged version of a giant tortoise, but it is very slow due to its heavy body.

"It's slow, it doesn't seem terrible!" someone said, this giant beast is indeed very slow, it can only be described as a no, from this point of view, it seems that the four of them are not very dangerous.

"Sea Xuan Turtle!" Mo Tian is face changed greatly, he blurted out, and then the speed accelerated, quickly retreating, it seems that in the past twenty years, some of the books he has checked have still played a role, and he finally knows some things in the sea, this giant beast, he will recognize.

As soon as his words fell, the giant beast opened its mouth, and the water around it increased, and whirlpools of shimmering blue light appeared one after another, rolling towards them.

These whirlpools spewed out by the giant beasts, making a hissing underwater sound, with the blue faint brilliance, the momentum is huge, and the power must not be small, even if they are in the foundation building period, they have to toss a lot.

As soon as Mo Tian spoke, he retreated, and of course the others were not slow, and followed him back quickly.

The bottom of the lake was soon overturned by the whirlpool of this giant beast.

Even though Lin Shan was not slow, he still felt a stronger suction force coming towards him, and he propped up the aura shield to the maximum, so that he could support his body and not suck it back.

The four of them ran for a pillar of incense at the bottom of the lake for about a long time, and only then did they get out of the attack of this giant beast, maybe they couldn't find their target, and the water gradually quieted down, and finally calmed down.

"This giant beast, the sea turtle?" Seeing that there was calm in the rear, the four of them had already run a long distance, Xu Fu asked.

"Sea Xuan Turtle, a giant beast in the sea, slow speed, strong defense, also belongs to sea cultivation, look at the appearance of this sea turtle, it should still be in its infancy, that is, the second-order sea cultivation, the third-order sea turtle, there are hundreds of zhang in height, it seems that because there are many sea cultivators in the sea, there are many crises, this sea turtle ran to Tongtian Lake. Mo Tian also stopped, turned around and looked back, there was a trace of sadness on his face, if this giant beast was guarding here, and the cave was not far from it, then things would be tricky.

"Second-Order Sea Cultivator, why don't you kill it?" Xu Fu also considered such a question, his eyebrows raised, and his murderous aura suddenly rose.

"It's difficult, even if it's a second-order Sea Xuan Turtle, its defensive ability is at least the Jindan level, and it's too much movement in the lake, if it attracts other sea cultivators in the degree, or if there are signs to spread to the shore, things will become more and more troublesome. Mo Tian immediately shook his head and stopped the thought.

"What about Lin Daoyou?" Yang Li looked around, and Lin Shan's figure disappeared.

"Fellow Daoists, there is a situation here. Xu heard Yang Li's voice, and Lin Shan's surprised voice came not far behind.
