In this empty underground palace, a cold breath was emitted. The entire underground palace was gloomy, as if in the darkness around, there were countless beasts staring at the visitor, and they could be snatched out at any time!

Mu Yi's spiritual sense instantly enveloped the underground palace and found that there were many formations in the underground palace, and the area of ​​the entire underground palace was hundreds of miles wide.

In Ang Lee's spiritual consciousness, Mu Yi also had some understanding of the general situation of this underground palace. The layout of this underground palace is extremely complicated, unlike the Nine Palaces and Eight Trigrams in Mu Yi's mansion, but refers to the special formations of alien races.

"Don't worry, there is no danger here. Now it is the underground palace of this general, no one will kill you!" Along the way, Yuwen Hu glanced at Mu Yi's tense expression and couldn't help but sneer.

He also has his own principles in doing things, and he will not do some things, just like using the lives of those under Mu Yi to threaten Mu Yi. He thinks such things are shameful and stupid, and he is not worthy of his current status as Otsukaku. Perhaps if Mu Yi was among the twelve generals, he would have changed a little.

But not killing Mu Yi now does not mean that Mu Yi can leave safely.

"I really don't like Otsukasaki's credit! When I first came to the precious land, I'd better be more careful to avoid having another conflict with Otsukasaki!" Mu Yi sneered.

Although it would be impossible for him to enter this underground palace, if the two of them solved the black robe, it would probably not be so easy for Mu Yi to leave this underground palace safely.

Under the leadership of Yuwen Hu, Mu Yi crossed the formations and finally arrived at the place where the black robe was located.

That place was a square secret room, and there was a formation gate with colorful spiritual light in front of it. This formation gate completely isolated the exploration of external spiritual consciousness.

"This is the sealed place of the black robe. Three years ago, I defeated Yuwen Jue and handed Yuwen Jue to the black robe. After that, the black robe absorbed Yuwen Jue's purple luck and went into seclusion and refinement here. The formations inside were all set up by him, and there should be three layers." Yuwen Hu explained quickly.

"Mu Yi, I tried to crack this formation many times, but I couldn't break it. Even if I use the power of the sky stone, the same is true. In my opinion, these are all your secret techniques! Next, it depends on your ability!" Yuwen Hu reminded again.

Mu Yi walked forward. When he approached the formation barrier, a black mist suddenly overflowed from the formation, and the black mist was extremely cold.

"Is this the breath of the black robe?" Mu Yi said in surprise. The fog was so cold. No wonder this underground palace was so cold. It was here.

"That's right, this is the breath of the black robe. Now this formation has been a little sparse, and the black robe should be out of seclusion soon!" Yuwen Hu said again.

Yuwen Hu would be so anxious to want this secret technique because the black robe is about to come out of seclusion.

"So that's it. No wonder Venerable Poison Dragon cannot break the first layer of formation barrier at all, because this formation is completely condensed by the power of the soul, and even the strongest spiritual power cannot be broken. But then again, what kind of person is that black robe?" Mu Yi said in his heart.

"You retreat, I will break this formation first. If you don't want to make any mistakes, don't disturb me!" Mu Yi said immediately, and Yuwen Hu also took a few steps back after hearing this.

He really wanted to see how Mu Yi's secret technique was activated, but since Mu Yi was so damned, he had to give up this idea.

However, as long as the black robe is killed, the secret technique has nothing to do with him. The most important thing at the moment is to remove the hidden danger of the black robe.

Mu Yi waved his right hand and a formation separated from them. Then, Mu Yi pinched his hands with his hands and quickly stimulated the secret technique of the Heavenly Spirit. Mu Yi pressed his right hand on the formation barrier.

Immediately, the formation was slowly melted away, and the secret technique of the heavenly spirit was introduced into the formation, as if it was like a fire storm, quickly eroding the breath of the black robe.

This first barrier was easily untied by Mu Yi.

"Unlocked... This is the secret technique to kill the spirit body? It really has miraculous effect!" Yuwen Hu exclaimed, and saw that the first barrier faded away quickly, and another seal suddenly appeared in front of him.

"There is the second seal formation ahead. The first seal can be broken without a breath. Then the second seal formation may take a little more time, but it should be able to be unlocked in just one moment." Yuwen Hu said in his heart.

Mu Yi stepped closer to the second barrier, and Yuwen Hu hurriedly followed Mu Yi, and he was looking forward to it in his heart.

At this moment, Mu Yi pressed his palm on this barrier, and the second barrier was quickly cracked, and it was also effortless.

"It was untied so quickly again... This is really a barrier set under the black robe?" Yuwen Hu was a little suspicious. Why did this barrier that left him helpless actually turned into a piece of tissue paper in Mu Yi's hand and easily cut it.

The power of this Tianling Secret Technique had exceeded his expectations. It seemed that the difficulty of killing the black robe was not as difficult as he expected.

In front of me, there was only the third layer of barrier formation left, and Yuwen Hu felt even more nervous. He didn't know how powerful this black robe had been in seclusion for many years. Can Mu Yi join forces with him really kill him?

The black robe is a spiritual body, and its role is not very important. Killing the black robe requires Mu Yi's secret technique of heavenly spirit.

But at this time, Mu Yi stopped and did not continue to break through the third formation.

"Well? Why don't you continue to break through the third formation?" Yuwen Hu asked in surprise. Did Mu Yi regret it? He was very worried about this in his heart.

The first and second layers of formations have been broken. If Black Robe comes out of seclusion, he will definitely know his motive. If they don’t kill Black Robe now, then they will never let him go when Black Robe comes out of seclusion.

"Yuwen Hu, where is the Nanming relics?" Mu Yi asked firmly at this time.

"I will definitely give it to you after the matter is done!" Yuwen Hu said quickly. He immediately understood what Mu Yi meant, and he couldn't help but feel angry.

"No, you have to hand it over to me now. Do you think I can escape from here? There are your formations everywhere in this underground palace!" Mu Yi said immediately.

"Mu Yi, are you going back on your word?" Yuwen Hu said furiously. Before he started killing the black robe, he actually wanted the Nanming relics first.

"If you go back on your word, are you still qualified to say this? You can't give it to me, but you should know the consequences! Do you want to kill me? If I have a pyramid formation, you can't hurt me at all. Do you want to trap me? Once the black robe comes out of seclusion, do you still have a way out?" Mu Yi said one by one.

Yuwen Hu suddenly became nervous, and Mu Yi's words penetrated his heart, which was also his current situation. But when he thought about it carefully, although Mu Yi's secret technique of heavenly spirit is effective for spiritual power, it is just an ordinary secret technique for these monks.

This is his underground palace, which not only contains many top-level formations, but also has a large number of cultivators on the mansion. With Mu Yi's cultivation level, he could not escape at all.

Yuwen Hu stared at Mu Yi coldly with his eyes. After hesitating for a long time, he also made a decision.

"Mu Yi, I hope you can trust your words. If you dare to fool me, then anyone in your mansion will die!" Yuwen Hu shouted coldly.

His right hand swept through the air, and a black cavity appeared in front of him. Yuwen Hu reached into the black cavity with his right hand and handed a huge and glittering relic to Mu Yi. This relic was the fifth relic, the Nanming relic.

Mu Yi took the relic at this moment and felt the strong relic aura coming into his body from his hands. This power was indeed more powerful than Chongming relic and Jialou relic.

This Nanming relics slowly sank into Mu Yi's palm and merged into his body. Now there are five relics in Mu Yi's body.

The boneless relics with no sequence number, the fifth Nanming relics, the ninth Jialou relics, the tenth Chongming relics and the 49th Lingxi relics.

In Mu Yi's body, the power of his three families became even more unbalanced, and the power of Buddhism was far stronger than that of Confucianism and Taoism.

"You can start!" Yuwen Hu reminded in a cold voice.

Mu Yi came back to his senses from his thoughts. He had something even more dangerous to wait for him! The third formation showed a burst of cold black aura, which was attached to a huge stone gate like thousands of years of black ice.

Mu Yi condensed his spiritual power with his right palm and silently recited the mantra of the secret technique of the Heavenly Spirit in his mouth. He pressed his palm on the third formation, and an extremely cold aura came from the palm of his hand.

Inside the stone gate, a force began to move tide, and the black mist overflowed from the formation even more violently.

"Come...who...who..." The stone gate came, and a heavy and angry voice came from the black robe.

Yuwen Hu held his hands tightly, and the black robe inside the stone gate had been awakened.

Suddenly, a crisp "bang" sounded, and the third formation fell down like an ice sculpture shattered, and a majestic black spiritual energy surged out from the gate.

A strong wind rushed out of the gate and the gate opened instantly. The fierce and cold black wind blew towards Mu Yi and the others. Mu Yi looked at it intently and found that there was a piece of ice and snow inside the stone gate.

"Yuwen Hu, I'm so brave, I actually disturbed my practice!" An angry voice from the black robe came from inside. Mu Yi and Yuwen Hu quickly entered the stone gate, and they came to this ice and snow.

"Mu Yi, where is he?" Yuwen Hu asked in a voice transmission. It was dark and he could not even notice the breath of the black robe when he opened his spiritual sense.

"The secret technique of heavenly spirit, all things are radiant!" Mu Yi quickly stimulated the secret technique.

A soul power came from Mu Yi's body, spreading across the ice and snow like a prairie flame. This world was swallowed by Mu Yi's secret technique like an illusion.

"Well? Who are you?" Black Rou asked in surprise, and the illusion he set up was easily unlocked. In the darkness, Black Rou's figure slowly condensed in front of Mu Yi and Yuwen Hu.

His eyes gathered inspiration and glanced at Mu Yi. He found that Mu Yi was only the cultivation level of the six-star master, and he was forced to improve.

But a person with such cultivation can easily break his illusion.

"Black Robe?" Mu Yi whispered.

Yuwen Hu found that the aura on the black robe had indeed become even more fierce. Standing in front of the black robe, he always felt suppressed. That power was obviously different from the power of the mysterious spirit, and it was another indescribable force.

But Yuwen Hu found that Mu Yi's expression was extremely calm and natural. Under the suppression of this inexplicable force, Mu Yi seemed extremely relaxed.

"Little kid, who are you? Are you Yuwen Hu's subordinate?" Hei Rou asked with a sneer, and he looked at Yuwen Hu in a blink of an eye. "I already knew that you had the intention to rebel. Now I have found a celestial master to come over, and I think you are sure to win? Hahaha..."

"A Tianshi Master is enough to kill you!" Mu Yi sneered, and a dazzling white light emitted from his body, and the breath of the secret technique of the heavenly spirit was transmitted from the white light.
