Late at night before departing for Xingli City, a sneaky figure slipped out of Yun's house and headed straight for the school.

His steps were light and steady, and at the same time he was able to maintain a rapid pace, so that in the distance of night, only a black shadow could be seen "whizzing" by.

The view near the school field is wide, and the moon and the accompanying moon reflect each other in the night sky, and the luster sprinkled illuminates the rushing black shadows.

The sixteen-year-old Feng Huan's face was childish, but there was still a depth in his eyes as always.

He walked through the schoolyard, stood still about halfway to the sea, took out a drawing from the jade letter he had with him, and looked at it in the moonlight. Xu is has been mixed with Ning Hezhi for a long time, and his demeanor has a little more elegant temperament.

"It should be nearby, and the entrance can only be ......"

Feng Huan touched his chin and muttered to himself, and then looked around left and right.

About a month ago, he was promoted to the Shouzhong realm, and this kind of promotion speed, if in the eyes of outsiders, he is one in a hundred.

But Feng Huaijin was already at this level three years ago, and now he doesn't know how much he has surpassed him, seeing that there are only two years left in the five-year covenant, it is impossible to say that he is not in a hurry at all.

The titular master, Yun Xuan, has been away from home for three years, and he never cares how much he has grown. That is to say, Yunyan is indeed outstanding, and he has given him a lot of help in cultivation, otherwise he would have stepped on a huge pit.

Thinking of this, the pace of the wind and bustle became more determined. You can't just expect others, you have to explore yourself.

Now, for example, he is looking for a "treasure".

Since three years ago, he accidentally touched that hidden realm in the school field, and Feng Huan has tried in the same place countless times, but he has never been able to do it.

However, he and Ning Hezhi talked a lot about the topic of the ancient beast taming field, and he was sure that no matter whether the strayed into the hidden machine realm was related to the school field, the school field, an abandoned ancient beast training field, must have a secret buried.

And just a few days ago, Feng Huan felt that he was close to the truth.

At the beginning, Yunyan told him that in order to suppress the violent nature of the aquatic demon beasts, the beast taming farm group in Gurong City used six dragon soul stones to set up an array. The painting of Ning He is more intuitive, and you can see that these dragon soul stones are scattered in six directions, enclosing all the beast training fields in them.

There are many people who don't know the Long Soul Stone, so in the eyes of others, this is indeed just a simple suppression array.

The problem is that the array is not made of ordinary jade.

The power contained in the Dragon Soul Stone was so powerful that it changed the original function of the circle.

In the same way of arranging the formation, the Dragon Soul Stone Tepe actually has extremely strong defensive power, and it can't suppress the demon beasts at all, so it makes sense to say that it protects the beast taming field from being destroyed.

Then the contradiction comes, there are only a few animal training fields, why do you need to use defensive circles? and even disguise them as ordinary suppression circles to arrange?

According to Ning Hezhi's description, most of the literature about the ancient beast taming ground in Rongcheng is incomplete, but many of the authors said that they had referred to a book called "The Wrong Map of the Northern Stygian Sea".

And the name of the author of "The Wrong Map of the Northern Stygian Sea" is still engraved on the stele outside the school yard - he is the person who funded the construction of the Rongcheng Ancient Animal Breeding Farm Group.

All of this adds up to a bold hypothesis in Fenghuan's mind.

Could it be that this author deliberately wrote the wrong name of the circle?

Based on this, it can be deduced that perhaps the construction of the animal training farm itself is a cover-up.

After flipping through a large number of books related to the circle, Feng Huan found an ancient circle called "Seven Lives Dao".

Compared to the defensive magic circle of the Seven Lives Dao, one more Long Soul Primordial Stone was needed when arranging the array.

This array was only used in the Wuzhou Purgatory, where the most vicious criminals were imprisoned, and it really had the effect of suppressing the violent nature of living beings.

That is to say, if the assumption is true, according to the other six known Long Soul Stones, there should be a Long Soul Stone used to arrange the formation somewhere at the bottom of the school grounds.

It's more likely that, for some reason, something that was supposed to be suppressed here escaped, and the animal taming farm was abandoned. And the later people didn't know the truth, so they only took away the six dragon soul stones on the surface, and the remaining one is still in the ground.

In this way, it makes more sense that there is still a residual force field of the Long Soul Stone in the school field, and the reason why the wind can touch the realm of hidden machines seems to have been found.

But all of the above can only be regarded as a reasonable speculation, and Feng Huan hopes to find evidence before leaving Rongcheng.

The Seven Lives Dao Circle of Purgatory is said to be laid by the disappeared ancient gods, and Wuzhou Purgatory is located in the center of the continent, far from Rongcheng at the northeast end of the continent, what connection can there be between the two?

Feng Huan's eyes were full of energy, and he might be able to get clues from the ancient gods on this trip. No matter how bad it is, maybe you can take a piece of Longsoul Rough Stone for nothing.

Wind Hustle has done a lot of things in the past three years, and he actually has a guess about where the underground entrance is.

He carefully explored the topography of the coastal waters of Rongcheng, where the coastline was smooth and shallow beaches. Only to the north of the school field, at the mouth of the Xia Ze River, the underwater slope increases sharply.

After diving less than ten feet, you can see an underwater valley on the continental shelf, and in the valley, a huge cave is hidden behind the current.

However, if the ancients really dug a tunnel in the sea and built a beast taming field in order to suppress something, and used the Long Soul Stone to set up a suspicious array, the cost would be too great. With this kind of kung fu, it might be easier to take that thing directly to Wuzhou Purgatory.

Before, the wind hustle realm was too low, and he estimated that he couldn't explore the entire cave, and he had doubts about whether this cave was an underground entrance, so he gave up for the time being.

Since he had just improved his realm before going out to study, and there was nowhere else after the possible entrance was checked, Feng Huan wanted to explore it again.

The process of diving to the cave is very familiar, and it basically does not take much physical effort.

The length of time a martial artist holds his breath is related to the amount of vitality in his qi sea, and a martial artist who guards the middle realm can generally dive in the water for up to half an hour, but the perception distance will be reduced to half.

The wind drove a small light shark to swim ahead and followed the cave without hesitation.

The light shark has light-emitting organs on both sides of its abdomen, which can be used for lighting, and the light shark is born in the ocean, and it can also give timely warnings if there is danger ahead.

The cave extends at a slightly downward angle, but the water flows strangely towards the outside of the cave, but fortunately, the flow is gentle, so I don't feel a big obstacle when I pass through.

There is a small amount of coral seaweed growing on the walls of the cave, and after a long dive, the creatures slowly decrease and the cave becomes narrower.

When the diameter of the cave shrank to about half of the entrance, the light shark in front of it suddenly stopped moving forward, but turned in place several times. It's not a reaction to danger, it's a bit overwhelming.

Wind Storm went up to check the situation, but was surprised to find that the cave had come to an end.

There seemed to be a light source overhead, and the wind roared towards the light source, and it came directly to the surface of the water - the end of the cave was originally connected to a pool of water.

Beyond the pool is a huge space, surrounded by fluorite stones embedded in the stone walls, emitting a faint pale green light.

Near the edge of the pool, you can see an obvious artificially hewn staircase, and it is a wide platform that goes ashore along the stairs.

At the end of the platform, a heavy stone door was shut.

The whole space was unusually quiet, not even the sound of running water could be heard, only the sound of water droplets dripping on the stone floor on Feng Huan's body echoed leisurely.

Extrapolating the distance based on the time traveled, this place should be very deep underground, very close to the previously assumed location of the existence of the Long Soul Stone!

It turns out that there is really an underground entrance, and it is so easy to find it!

The wind couldn't hide the excitement in his heart, and he completely forgot to think about the reason why the lamp shark was hovering, and walked directly to the stone gate.

However, the moment he touched the door, in the quiet space, someone's singing suddenly exploded in his ears!

Feng Huan was startled, and thought that someone had quietly attached to his ear, and when he saw that there was no one behind him, he instantly became vigilant, and listened carefully with his vitality, trying to identify the source of the sound.

The sound was a humming of repeated chapters, so high that it was impossible to tell whether the speaker was male or female.

At first, the humming sound sounded inexplicably pleasant, but after listening to it for a while, Feng Huan felt that his brain was about to explode.

In order to relieve the headache, Feng Huan plunged back into the pool.

After soaking in the water, the sound really became much quieter.

I wanted to wait for the humming sound to die down and then go out to find out, but when I retracted into the cave, I realized that the lamp shark was gone!

The danger awareness of a guy like the lamp shark is notoriously high in the sea beast circle. When the tamed lamp shark detects danger, it will change the glowing color of its abdomen to alert its owner.

If it weren't for the fact that he couldn't speak underwater, he would have scolded on the spot.

didn't even give a reminder, and ran away without a trace?

Not thinking about how to open the stone gate, Feng Huan hurriedly swam back, and the threat lurking here seemed to be greater than he imagined.

I don't know if I was in a hurry because of my panic, but the way back was obviously downstream, but I was several times more tired than when I came.

When I finally swam to the exit, most of my vitality had been consumed, and at this moment, strings of bubbles suddenly surged under my feet.

Wind Hustle had a bad premonition and swam towards the exit at an accelerated pace, only to hear a buzzing sound from the depths of the cave, and then the direction of the water suddenly reversed!

Feng Huan was dizzy by this and choked on a mouthful of water.

If you don't swim out of this cave now, you will only be carried deeper and deeper by the current, and your vitality will not be able to support the time to swim back and forth again!

Feng Huan riveted his strength, and first struggled to stick to the cave wall, and the coral seaweed or rocks that he could catch at hand became a help for him to climb forward. The current was fast, but he managed to keep it from being washed away.

Luckily, after this wave, the flow of water in the cave slowed down. Feeling that he had reached his limit, he took advantage of this gap and rushed out of the cave.

The underwater valley is still some distance from the sea, and the wind hustle and bustle, exhausted with all his strength, knows that he has to go upstream, but his limbs can't make a matching reaction, and the whole person sinks straight down.

In a trance, Feng Huan seemed to see someone stretching out his hand to him.

Is it a dream?

He had had countless dreams of falling into the water before, in which a woman reached out to him.

Wind Hustle struggled to open his eyes, but he still couldn't see clearly.

The water in the dream was too dark, as it is now.

No, it seems to be brighter now.

Is that...... Lamp shark?

The wind woke up suddenly.

The lamp shark that slipped away before him had been waiting at the entrance of the cave, and the lamp shark was there, indicating that there was no danger nearby.

And in the waters illuminated by the lamp shark, someone really stretched out his hand.

Not one person, it's two people.
