Qin Huai naturally learned the secret of the demon cave here from Meng Ji's mouth.

It turned out that thousands of years ago, this Meng Ji infiltrated the heavenly realm to investigate an extremely secret matter, and after many twists and turns, he finally found clues, but his whereabouts were revealed and he was besieged and killed by the army of the Heavenly Palace.

In desperation, Meng Ji had no choice but to resort to the forbidden art of the underworld, and at the cost of burning his life, he forcibly broke through the space and fell into the human world, but he was also seriously injured because of this, and the holy relics of the Three Realms Stone he carried with him were also missing.

Meng Ji knew that his life was short, so he built this demon cave and buried himself and the secrets he knew deep underground.

But after Meng Ji's death, there is still a wisp of residual consciousness that has not been resolved, and he has been stuck here. It wasn't until Qin Huai's arrival that he spied a trace of secret from that special true qi and concluded that Qin Huai was the one who could be trusted, so there was the deal with Qin Huai.

This Meng Ji is a Nine Shadows Troll, which was not tolerated by this side of the world, and after death, his body could not return to the underworld, and turned into rolling demonic energy, and was sealed in the demon pool deep underground by the peerless array that he had arranged in advance.

However, the real seal was in another space underground, and the outer spirit sealing array was not set by Meng Ji himself, so there was probably another hidden story in this matter, but the purpose of the person behind it was unknown.

In this way, the leakage of Luoyang demonic qi should be due to the problem of the demon pool, not the loosening of the outer seal. Therefore, what Qin Huai had to do at this moment was to go to the depths of the earth to explore the magic pool, and by the way, take out what Meng Ji said and restore his previous memory.

In front of the magic pool, several black-clothed people gathered in a circle, each pinched out a magic trick, and injected a stream of pure black qi into the pool.

The aura emitted by these black qi was no different from that in the pool, and it was obviously extremely pure demonic qi.

These people are actually rare demon cultivators in the world!

With the injection of these black qis, the demonic qi in the pool suddenly surged, and the demonic qi entered by the man in black gradually showed a convergence trend.

And with the stirring of the demonic qi emitted by these black-clothed people, deep at the bottom of the pool, it seemed that something had been pulled and was about to come out.

Above the surface of the pool, black thunder faintly appeared, causing a pool of black water to crackle.

However, at this moment, a golden rune suddenly appeared in the depths of the bottom of the pool, surging up quickly, and then a golden light burst out, which immediately bounced these black-clothed people away.

Several black-clothed people were caught off guard, and immediately spurted out a mouthful of blood.

Without the maintenance of the man in black, the pool noodles returned to calm.

"There's really a backhand!"

The man in black snorted coldly, and then took out a few black beads from his arms.

A palpitating energy fluctuation emanated from the bead, and it was the real magic bead!

"Fortunately, the master foresaw it and broke it for me!"

The man in black sneered, and then several drops of blood dripped on the magic bead, completely activating the magic bead. Inside the True Demon Bead, a violent energy fluctuation quickly spread, and then, with another pinch, the True Demon Bead came out of his hand and flew straight towards the Demon Pool.

Obviously, the man in black wanted to use the True Demon Bead to blow up the golden seal.

However, just when the True Demon Bead was about to fall into the Demon Pool, a cold current suddenly hit, and the air and the demonic qi seeping out along the way quickly condensed, and the several True Demon Beads were also frozen on the surface of the Demon Pool in an instant.

"Not good!"

The faces of these black-clothed people suddenly changed greatly, and these few true magic beads exploded in an instant, followed by an extremely violent energy fluctuation spreading, and before they could react, these black-clothed people were immediately submerged in endless demonic energy.

When this energy dissipated, a few figures finally appeared not far from the magic pool, and it was Qin Huai and the others who came at the critical moment.

Qin Huai stepped forward, and when the black-clothed people had fallen to the ground, Qin Huai took a look at the mask, and saw that these people were tattooed with a blood-red pattern between their eyebrows, which looked like a ghost, but it was plausible.

"It's from Vientiane Gate!"

At this time, I saw Shi Shouyi take a step forward and recognize the identities of these people at a glance.

"Vientiane Gate?"

Qin Huai frowned, he had also heard of this Vientiane Gate, a hundred years ago, it was also a great sect of the Demon Dao, and later in the battle of the Righteous Demons, it was broken by the Righteous Dao Alliance, and the Vientiane Gate was destroyed, and after that, there was no trace of the Vientiane Gate in the cultivation world.

This Vientiane Sect disciple has reappeared in the rivers and lakes, could it be that the Demon Dao has revived again?

Shi Shouyi pondered for a while: "Vientiane Gate, where did they learn about the secret here? It seems that they all came prepared, and I am afraid that there are more than a few of them in this demon cave. ”

"They...... Could it have something to do with the Demon Venerable?" a bold idea suddenly appeared in Qin Huai's heart.

"If that's the case, then I'm afraid it's not that simple!"

"It's not good, quickly seal the magic pool!"

Qin Huai suddenly thought of something, and his face changed greatly, and he immediately pinched out a magic trick, and injected a seal into the magic pool.

As this seal entered, a golden rune once again appeared in the depths of the bottom of the pool, but it echoed Qin Huai's seal.

The rune quickly flew out of the bottom of the pool, hovering in mid-air on the surface of the pool.

Then, Qin Huai once again pinched out a magic trick, and a pale golden true qi merged into the rune, and the rune suddenly emitted a mysterious golden light.

The golden light sprinkled down, like a layer of golden veil, slowly gathered the black qi in the pool, and finally all merged into the bottom of the pool.

At the same time, under the repair of that golden light, the crack on the surface of the pool that was broken by the black-clothed men also slowly healed, forming a thin curtain of light shrouded above the magic pool.

This method is the technique of rearranging the seal of the magic pool according to Meng Ji's description. As long as the demon source can be isolated here, the true demon qi at the bottom of the pool will be locked in the depths of the earth forever, and will be purified by this realm bit by bit as the years go by.

However, this method can only be used to block the leakage of demonic qi for a short time, and in order to completely seal the demon pool, you have to take out a strange treasure left by Meng Ji, the Divine Demon Ding.

Only with the help of the purest and purest spiritual power in the Gods and Demons can we resist this supreme yin and fierce true demon qi.

The next moment, Qin Huai was reciting a mantra, and a stream of mana entered the void above the demon pool.

Above the magic pool, a sudden gust of wind and clouds surged, and a small whirlpool appeared.

In the middle of the whirlpool, lightning flashed and thundered, and the sound of purple electricity was endless, and in the center of purple electricity, the entrance of a passage appeared.

"Let's go!"

Qin Huai immediately made a decision and took the lead in entering the passage, while the rest of the people followed closely and followed one after another.

This is a hidden space arranged by Meng Ji with a wonderful formation, hidden somewhere in the depths of the grotto, extremely secret. If Qin Huai hadn't known the way to enter, he wouldn't have been able to discover that there was such a passage hidden above the demon pool.

Not long after, Qin Huai and the others appeared in a stone hall. Although it is not as wide as the place where Meng Ji is buried, it is more magnificent.

On all sides of the main hall, there are unusually flat stone walls. On the stone wall, all kinds of patterns were painted, some were demons in the underworld, some were races in the heavenly realm, and there were also many races that Qin Huai had never known. These patterns are connected one by one to form a whole, probably recording Meng Ji's magnificent life.

When I first saw Meng Ji's crippled understanding, the other party was like an unruly prodigal son, and he didn't bring Qin Huai the slightest oppression, but after looking at these portraits, he realized what a terrifying existence this Nine Shadows troll used to be.

In the middle of the main hall, there are three stone statues, all of which have three heads and six arms, making a posture of lifting, but there is nothing in their hands.

Qin Huai didn't stop for long, after looking at it, he immediately recited a mantra lightly, and then pinched out four magic seals and punched them into the four walls.

On the wall, there was a burst of dark light, and then Qin Huai's eyes moved, only to see the patterns on the wall as if they had come to life.

These patterns were aligned with the scattered stone statue, and with a finger of his hand, a series of dark points of light suddenly flew towards the stone statue.

These points of light converge and gradually form a cluster of light.

The light continued to grow, as if enveloping something, and slowly rose from the hands of the three stone statues.

When the light mass rose to its maximum, no more light spots flew out of the surrounding stone walls. Then, the point of light contracted sharply, quickly converging towards the black shadow wrapped in the center.

Not long after, a small black tripod appeared in front of Qin Huai's eyes, and a desolate aura spread out, and the Xuanguang floated on the tripod body, and the word "gods and demons" was engraved impressively!

Qin Huai's face was overjoyed, this tripod was not only the key to sealing the magic pool, but also an opportunity for him to unlock his memory.

But at this moment, suddenly several golden rays appeared, and it was a few golden feathers, which suddenly attacked everyone.

Everyone was shocked in their hearts, and they used their means to resist.

Taking advantage of this opportunity, Xiao Qianyu crossed everyone in one fell swoop, appeared in front of the God and Demon Ding in the blink of an eye, and reached out and grabbed the God and Demon Ding in his hand.

It turned out that after escaping from Kaimengji's coercion, Xiao Qianyu did not go far, but secretly monitored the movements of Ye Qing'er and others on the side.

Xiao Qianyu hid his breath, followed all the way, and followed him to the main hall here, until Qin Huai used a secret method to unlock the seal of this god and demon tripod, and then he suddenly became troubled and caught the god and demon tripod in one fell swoop.

Speaking of which, the concealment method of this Thousand Peerless Sects is indeed unique, and several outstanding disciples of the three major sects of Rao are here, but they have not even been able to detect half of it.

However, before Xiao Qianyu could grasp it, he suddenly saw a mysterious light shoot out, hitting the gods and demons directly. The gods and demons were suddenly shocked, and the artifact that had just arrived in his hand suddenly flew away again.

Xiao Qianyu's face froze, and he looked at the Xuanguang, only to see Qianqian standing not far away, a pair of watery eyes looking at him with a slight smile.

Xiao Qianyu was surprised, a chill appeared on her face, she didn't expect this seemingly inconspicuous little girl to find herself first, and it was in such a moment that her plan fell short.

"I want to think about the gun boy's things, Qianqian doesn't agree!"

Qianqian sacrificed the bell on her chest, and a crisp bell sounded when it hit, Xiao Qianyu's eardrums suddenly shook, and there was thunder rolling in her brain.

"It's ...... Hong Huang Ling!"

Xiao Qianyu's face changed greatly, and he ran several exercises to stabilize his mind in a row, which was able to resist the ringtone, and he had put away his contempt in his heart.

At this time, Qin Huai and the others had already reacted, and they all turned to Xiao Qianyu, and the long sword in their hands was unsheathed.

"Xiao Qianyu!"

Everyone's faces turned cold, and several sword lights slashed straight down.
