According to the law of the change of the exit at this time, the ghost butterfly has escaped to the fourth layer at this moment.

Mu Yu carefully calculated, if he wanted to chase him to the fourth layer, he would have to wait two hours at the fastest to enter the seventy-first layer, and wait another three hours before he could transfer to the fourth layer.

It is impossible for the ghost butterfly to stay on the fourth floor all the time, and the fourth floor will be connected to three places in the next five hours.

Mu Yu could be sure that Oni Butterfly would definitely leave through the other exit after entering the fourth floor, but it was difficult to say where she would appear in the next five hours, as Mu Yu couldn't know exactly how long Oni Butterfly would stay on a certain floor. If she stayed for an uncertain amount of time, she wouldn't be able to push out of the exact level of the tower she was going to.

He couldn't catch the ghost butterfly anymore.

"Mu Yu Xiaoyou, thank you for saving us, otherwise we would definitely not be the opponent of the ghost sect. ”

The deer boss was very grateful, although he didn't know what Mu Yu was worried about, but he also saw the appearance of the fleshy wings and horns of Zi Yan just now, and understood that the creature could not be touched, if it wasn't for Mu Yu's intervention, they would definitely be more and less lucky today.

"yes! I thought you would covet the Siren King's Thousand Feet of Dinghai!" the dragon turtle interjected.

Boss Deer immediately glared at the dragon turtle: "Don't talk nonsense, how can Mu Yu Xiaoyou be that kind of person! He is a friend of Lord Zhenlong, a friend of our demon clan." ”

Mu Yu shrugged his shoulders indifferently, to be honest, he was just amazed by Dinghai Qianqi, but he didn't have much covetousness, after all, this thing still belonged to the Siren King in the end, and since the Siren King was going to be born, then Mu Yu didn't need to fight for anything.

"Where did you get Dinghai Qianqi?" asked Mu Yu.

After entering the Demon Town Tower, everyone was randomly teleported to any floor, and Mu Yu didn't know how the deer boss was targeted by the ghost gate.

"I found it on the eighth floor, and then I was discovered by two ghost sect people, who wanted to take away a thousand feet of Dinghai. The ghost gate people have twins, which are very difficult, so I can only escape, and finally get rid of them, come to the layer of the snow mountain just now, meet the little dragon turtle, and then be chased by the ghost gate. Boss Deer said briefly.

As for how Dinghai Qianqi was found, Boss Lu didn't say it clearly, and Mu Yu didn't ask in detail. He was sure that Boss Deer had used some kind of secret magic to break the seal, after all, Dinghai Qianqi was a real person who would not throw it around.

"What are you going to do next?" Mu Yu continued.

Boss Deer hesitated for a long time, and said firmly: "Find the layer where Lord Siren King was sealed, and unlock the seal of the Siren King." ”

Mu Yu knew that the demon people came in to save the Kraken King, to be honest, if he didn't know that "the demon king must be born", Mu Yu would definitely not approve of the demon clan to rescue the Kraken King Yujiang.

In the rumors of the cultivation world, the Terrans recorded that the reason why the Demon Clan was suppressed was because in the struggle with the Yumeng Demon Clan, the Demon Clan helped the Terran to deal with the Yumeng Demon Clan, but put forward very harsh requirements, so the Terran finally wiped out the Demon Clan. But now that Mu Yu has learned a little truth about the past, he understands that things are far from being as simple as he imagined.

"Do you know what layer the Siren King Yujiang is sealed on?" Mu Yu asked.

Now that the Siren King Yujiang must be rescued, then Mu Yu can help. The place where the Kraken King was sealed must have the strictest guardian formation, and it was impossible to rescue the Kraken King.

The deer boss and the dragon turtle glanced at each other, and the deer boss replied: "According to the speculation of the demon souls on the island that have been sealed for five thousand years, the Siren King is sealed on the top floor, but we don't know how to get to the ninety-ninth floor, the exits here are all random, we can only try our luck." ”

"Don't leave it to chance, I know how to get to the ninety-ninth floor. Mu Yu said.

"Really?isn't Mu Yu kidding?" Boss Lu was a little suspicious, he didn't have Mu Yu's ability to deduce, and he didn't know which level these passages would lead to, so he could only wander around like a blind cat touching a dead mouse.

To be honest, it's not just him, I'm afraid that none of the people who come in can know the secret of the Demon Suppression Tower, and the magic weapon of Xuanjizi Zhenren is not so easy to be known.

"Believe it or not, we're not interested in finding the Siren. Long Teng snorted on the side, very dissatisfied with the question of the deer boss.

Boss Lu hurriedly lowered his head respectfully, and said seriously: "Lord True Dragon's forgiveness, I am not questioning Mu Yu Xiaoyou, if Mu Yu Xiaoyou can help us find Lord Siren King, we will definitely be grateful to Mu Yu Xiaoyou!"

"Okay, now you go back to the first floor, which is the first floor of the Snow Mountain, wait for half an hour, and then the entrance will lead to the twenty-sixth floor, you will wait for two hours on the twenty-sixth floor, and then you will enter the thirty-first floor when you come out of the entrance, and wait for half an hour on the thirty-first floor, and then go through the entrance and exit for half an hour, and enter the ......."

Ki Yu pointed him out the easiest route, which required a total of twelve transfers and took at least sixteen hours!

The deer boss on the side heard it for the first time, and he hurriedly used his demonic power to engrave all the words Mu Yu said into a piece of animal skin, otherwise he wouldn't be able to remember it.

The deer boss looked at the demon text on the animal skin, and he was still suspicious in his heart, but he was afraid of annoying the dragon vine again, so he didn't show it. Besides, now they are also headless flies in the Demon Suppression Tower, so they simply give it a try.

"Where are you going?" asked Boss Deer hesitantly.

"We're going to settle accounts with the ghost people, you guys hurry up, the exit will change in another quarter of an hour, and then the route I give you will all be invalid, remember that you must act according to what I say, not too early or too late, otherwise you will miss the time and turn us to other places like chasing the ghost butterfly just now." Mu Yu said.

The deer boss nodded solemnly, and then returned the same way with the dragon turtle. Mu Yu, on the other hand, had once again planned a route to the eighty-first floor, where he had to wait for an hour before he could act.

Mu Yu has been thinking about the black and white spiritual power in his body next, it can be said that he was able to kill Purple Resentment completely by luck, if it wasn't for the fact that he recently found that he was able to gradually control and separate the black and white spiritual power, he would not have been able to kill Purple Resentment by dead air.

"Mu Yu, I still don't understand, when we met Akatsuki before, you were also sucked away by its Yellow Spring Corpse Water, why was it okay at that time?"

"Because of the balance. Mu Yu said.

At that time, when he was sucked away from his spiritual power, black and white spiritual power was mixed together, and one black and one white were maintained in a wonderful state of balance, so when he was sucked away, it was equivalent to normal spiritual power, and nothing would happen.

And Mu Yu is now more and more familiar with black and white spiritual power, he already knows how to separate black and white spiritual power, when Purple Resentment sucks away the dead air, he strips the dead qi from Mu Yu's body, the dead air is too terrifying, it can devour everything, and it can also devour Purple Resentment.

The most serious thing is that a small trace of dead qi is constantly surging and devouring, and if it is not dealt with in time, it will cause incalculable consequences, and eventually even destroy the entire triple heaven! At that time, Mu Yu was not sure if he could still control the surging dead qi.

"Then why is it useless for the Wood Spirit to deal with the Flesh-Winged Horn Monster, it's also dead!"

"Oh, big earthworm, are you a hundred thousand why? Why are you so stupid! The wood spirit was originally a vigorous thing, even if it was infected by the death qi, its death qi was still not pure enough compared to the death qi in Mu Yu's body. Xiao Shuai replied for Mu Yu.

"That's right, in short, in the future, except for dealing with the flesh-winged horn monster, there is really no way to separate the angry and dead at other times. Mu Yu shook his head.

Mu Yu Pan sat down to breathe for an hour, and no one came to this level at this hour, which also saved Mu Yu from dealing with unnecessary troubles.

After an hour, he finally got to work, following the route he had just re-deduced to the next level.

——

Outside the Demon Tower.

The souls of the human race and the soul of the demon race were anxiously waiting near the Demon Suppression Tower, and now both sides have temporarily put aside their prejudices and entered the Demon Suppression Tower for their own purposes. But letting go of prejudices does not mean that you can get along amicably, and the souls on both sides are still on guard against each other in case either side makes some out-of-the-ordinary moves.

Helian Kong looked at the Demon Tower, and he also sighed in his heart, he was trapped on this demon island for five thousand years, unable to get out, he didn't know what was happening outside, and he only faced endless bone battles every day, for the so-called dignity of the human race.

He was really tired.

Sometimes it is better to live in monotony than to die happily.

He wanted to leave the island, even if it was to die.

"I hope Mu Yu can help me fulfill this wish!" Helian sighed inwardly.

He pinned all his hopes on Mu Yu, as long as Mu Yu controlled the Demon Suppression Tower to release the confinement of the entire Demon Island, then he would be able to liberate himself and become a free soul and enter reincarnation.

Oniyuko and Oni Yeming were talking to each other sneakily away from the crowd, their expressions mysterious.

"I don't know if I have reached the eighty-first layer now, the Tianyan Reincarnation Seal is now the only hope for us to find the soul to return to the heart, if we can't find the soul to return to the heart......" Ghost Yeming frowned and didn't continue.

Ghost Yuzi pondered for a moment, and said: "The people of the Soul Crossing and the Moon God Clan must be done, when the Xuanjizi real person was still alive, I overheard some secrets of the Demon Suppression Tower, the ghost is a good seedling, he will not let us down." ”

"When are we going to do with these souls on the island?" Ghost Yeming glanced at the souls of the demon people who had been guarding not far away.

"Don't worry, these souls on the island are quite strong, much stronger than the souls of the outside world, if we can refine them into our magic weapons, it will be a huge fortune, but this matter must wait until the kid instructed by Heliankong breaks the realm of the Ten Thousand Laws of the Xuanji Zi Zhenren, otherwise the souls here are uncontrollable." Ghost Yuzi said lightly.

There are many reasons for the ghost gate people to come to the demon island, and taking away the thousands of souls on the demon island is also one of them.

Ghost Yeming stared at Heliankong in the distance viciously, and said fiercely: "That Heliankong who protects Mu Yu, I must control him! He wants to be free? Hmph! It's not that easy! I want to keep his consciousness and let him kneel in front of me, I want him to live in humiliation forever!"

Ghost Yeming is a person who must be revenged, and at that time, Helian Kong protected Mu Yu and attacked him, and he is still haunted by it!

Ghost Yuzi said lightly: "Don't worry! He can't get rid of it! None of the souls here can escape, once the Demon Suppression Tower dissolves the formation realm, all the souls, including the demon souls, will become our Yin soldiers and ghost servants, and Heliankong is no exception!"

The people of the Ghost Gate are ruthless, and it is unreasonable for so many souls on the island to free them.

Where would Helian Kong think that he just wanted to stop being trapped on the Demon Island and let Mu Yu contact the formation realm of the Demon Suppression Tower, but he didn't expect that the Ghost Domain would be against him for a long time!

The hands of Ghost Yeming and Ghost Yuzi were filled with a ghostly aura, silently spreading all around, blending into the void and disappearing.

A soul round-up is about to cover the entire demon island!
