After taking Bei Xueqing and the other two into the Spirit Gathering Cave, Yi Ming used the "Indifferent Escape" to fly silently towards the place where the magic light had just burst out.

As for why I didn't use another technique called "Spectral Invisibility Technique", it's because we are in the water now and "Spectral Invisibility Technique" is useless.

"Fortunately, the seabed is pitch black, and there are countless seaweed plants. Without spiritual awareness, it is basically difficult to see beyond three meters. This situation is not much different from using the Spectral Invisibility Technique."

While talking to himself, Yi Ming had already swam over ten miles and arrived at the place where the magic light had just burst out.

"Huh?"

Yi Ming looked around. The sea water here was extremely turbid, with scattered vegetation flying around. His spiritual sense was spreading, and he could feel that there was still some residual spiritual energy nearby. There were some ordinary fish and shrimp corpses nearby, but there was no residual aura of high-grade ferocious beasts. Instead, there was a rather regular spiritual energy of heaven and earth that was slowly stirring and dissipating.

"There are no ferocious beasts at the entrance to the underwater world. They just attacked together to break a formation." Yi Ming looked around and said, "It is a natural formation, at least of the upper grade of the Xuan level. As expected, there is no simple formation in the underwater world."

The big crack was only three feet wide, but as Yi Ming went deeper, the width of the crack not only did not narrow, but became wider and wider. However, the amplitude was not large. Yi Ming descended more than a hundred feet, and the width only increased by ten feet.

The correct content is in %六九% book'bar!

Compared to the big crack just now where there was no vegetation at all and it was all bare cliff walls, there was vegetation growing in this space.

"Logically speaking, even if there is a concealed formation, with such a long crack, there should be some cultivators or ferocious beasts who accidentally enter the crack, right?" Yi Ming raised his eyebrows, then floated closer to the crack.

Within Yi Ming's spiritual awareness, clumps of seaweed grew on the top of the space, swaying along with the water flow in the sea.

Yi Ming had just swam less than ten feet when the magic light behind him dissipated. It was obvious that the action just now was just a test or warning. In short, the two parties must have reached a compromise.

"Amazing! With this two-pronged approach, ordinary cultivators in the middle stage of Condensation cannot withstand it and can only go in." Yi Ming was a little surprised. "Once you go in, the pressure and suction will only get stronger and stronger. By then, you won't be able to get out even if you want to."

"The underwater world is so big, is it necessary to take action so quickly?"

The figure of a mid-grade Xuan-level spiritual plant was discovered in his spiritual consciousness. Yi Ming explored the surroundings but did not find any trace of the ferocious beast.

As soon as he approached the big crack, Yi Ming's body couldn't stop sinking. He felt that the pressure around him instantly tripled, making him feel like he was sinking faster.

“No wonder no one has discovered this underwater world and natural formation before. Only cultivators in the late Condensation stage can get out after entering. Others would probably die in here.”

The deeper Yi Ming dived, the greater the pressure from the sea water around him and the suction from below. Even with Yi Ming's cultivation in the late stage of Condensation Yuan, he gradually felt the strain.

The suction suddenly disappeared!

However, after he pulled out the spiritual plant and put it into the storage ring, he saw that some seaweed growing next to the spiritual plant seemed to tremble unconsciously.

At this moment, a mysterious light suddenly burst out in the distance, and then the raging spiritual energy and magical energy came over along with the sea water.

Therefore, after Yi Ming dived three thousand feet, the width of the big crack became more than thirty feet. It was no longer a crack, but could be said to be a valley.

That's it, it's not the bottom yet! "In fact, more than three thousand feet is only twenty miles, which is far from the theoretical seabed." Yi Ming thought to himself, "But this is an endless mountain range that almost sticks out of the sea. Twenty miles deep is already very deep."

Just when he dived five thousand feet below the crack...

But this has nothing to do with Yi Ming. He just came here to take advantage of the situation, so when he found a mid-grade Xuan-level spiritual plant on the cliff, he felt that he had made the right decision this time.

"Again? So soon?" Yi Ming raised his eyebrows, then swam away in the opposite direction.

Yes, water flows. In this space, the sea water is still flowing. It is not a pool of stagnant water like in a deep water cave, but is constantly moving.

But Yi Ming thought about it and decided not to give it a try. "Forget it. Curiosity kills the cat. There's no need to look for trouble."

Because Yi Ming came down along one side of the big crack, the top of this space was right next to him.

It was as if he was squeezed out of a passage and suddenly entered a new world. It was still the dark seabed, and the pressure was still ten times greater than the normal water pressure. After Yi Ming came out of the passage, he was quiet and motionless, then spread his spiritual consciousness and began to explore the surrounding environment.

"Strange, there are no ferocious beasts here?"

"Um?"

At the same time, Yi Ming also discovered a large crack in a valley.

However, Yi Ming was not in a hurry. It was not known whether this place could be considered a secret realm or an underwater world. Its scope was obviously much larger than the several underwater worlds they had explored before. In addition, this was the first exploration and there were only a dozen or so Nascent Soul cultivators. They could not finish the exploration in a short time, so there was no situation of too many people and too little porridge. This was also the reason why although some people had taken action before, they quickly stopped.

This huge crack is three meters wide and connects two cliffs at the end. It is also hundreds of meters long. No one knows how it was hidden by the natural formation before.

"This is just the spiritual plant growing on top of the underwater world, and it's close to the entrance. As we all know, the deeper you go, the more good things you will get!"

At the same time, due to the terrain of the large crack in the ground, a swirling suction force came out of the crack, sucking him downwards.

Yi Ming kept moving, leaning against the edge of the big crack, resisting the tremendous pressure and suction, controlling his descent speed, going deeper and deeper seemingly slowly but actually quickly.

Then Yi Ming left here lightly and continued to move slowly along the mountain wall at the top of the space, trying to explore the edge of this space.

…

Along the way, Yi Ming collected more than a dozen Xuan-grade spiritual plants, including a top-grade Xuan-grade one. The spiritual plant had more than a dozen fruits that looked like blueberries, and each of them exuded the aura of a top-grade Xuan-grade. Around this spiritual plant, there grew many seaweeds that were dozens of feet long, looked extremely soft, but sparkled with bright silver luster.

Yi Ming walked along the mountain wall for dozens of miles. After he harvested another Xuan-level spiritual plant, he suddenly felt a breath of energy. Then, not far from him, a turquoise light flashed by, and then countless bright silver lights burst out. It turned out that a cultivator was fighting with the seaweed growing on the mountain wall.
