Outside the hidden stone gate, Yuwen Hu had been watching the movement on the stone gate in alarm, and the changes in his body made him think about it. The spiritual poison left behind by the black robe has been constantly weakened, but it has never subsided.

After a long time, he felt someone fly out of him.

"Could this be Mu Yi?, or the black robe?" Yu Wenhu exclaimed, through this formation, he couldn't detect the other party's spiritual power at all.

Yuwen Hu held the long knife tightly in his right hand, and his expression collapsed. The spiritual poison in his body is very weakened, it should be that the black robe was killed, but the spiritual poison in his body has never completely disappeared, this is that the black robe has not been killed in the end, that is Mu Yi failed?

Yuwen Wu didn't dare to think about it, his whole body was stimulated with the aura of Xuan Ling, and he was ready to kill with one blow. Once the black robe appears, then this is the best time for him to assassinate.

In an instant, there was a fluctuation of spiritual power from the fourth formation, and there was no black mist coming out of that formation, but a burst of rich Xuan Ling Qi rushed out.

"Is it the aura of the Xuan Ling, is it Mu Yi?" Yuwen Go's eyes straightened, only to see Mu Yi rushing through the formation enchantment. Mu Yi's divine sense immediately locked on Yuwen Go's position, and he instantly flew down in front of Yuwen Go.

"Mu Yi, where's the black robe?" Yuwen Hu exclaimed.

"If the black robe is still alive, can I still come out?" Mu Yi said coldly.

He ...... Is he really dead?" Yuwen Hu said with joy in his heart, and the news shook his heart. He was a little unsteady in his heart, and he always felt that he couldn't believe that the black robe was killed without seeing it with his own eyes.

"This formation has been broken by me, you can go in and have a look at it at will!" Mu Yi looked at Yuwen Hu's uneasy expression and immediately said.

Yuwen Hu's divine sense quickly penetrated into that stone gate, and in that space, he only felt the residual breath of black mist, but at this time, he couldn't see the figure of the black robe at all.

"Was the black robe really killed by Mu Yi?" Yu Wenwu exclaimed, he thought about it carefully, Mu Yi's Heavenly Spirit Secret Technique was extremely easy to unravel the previous three formations, and he broke the black robe's move with a flip of his hand.

The spirit puppet created by the black robe, it took him a lot of time to kill it, but Mu Yi was able to kill it in an instant. This is not how high Mu Yi's cultivation and combat power are, but Mu Yi's secret technique, which is really effective.

The effectiveness of this secret technique has far exceeded Yuwen Hu's expectations.

It's not surprising that Mu Yi killed the black robe now. But Yuwen Hu always had some uneasy feelings in his heart, and secretly asked himself in his heart, is it because he still has spiritual poison in his body?

"Mu Yi, how did you kill the black robe?" Yuwen Hu immediately asked, "Quickly pass on your divine thoughts to me!"

"Yuwen Go, I promised you to kill the black robe, but I am not obligated to tell you all the details. You are also a monk, you should know the truth that the Fa is not spread!" Mu Yi shouted.

At this time, Yuwen Wu also knew very well that Mu Yi might have other tricks he didn't want him to know. But at this moment, Yuwen Hu's heart suddenly had a cold meaning.

He looked at Mu Yi with cold and gloomy eyes, and a murderous aura permeated the surroundings, "Mu Yi, don't forget that this is my underground palace, tell me everything, General Ben can let you return to the mansion safe and sound, otherwise, you will be trapped here for the rest of your life!"

Unloading the mill and killing the donkey, crossing the river and demolishing the bridge, that is a common means used by Yuwen Hu.

There are no eternal friends and enemies in this world, only eternal interests! Before coming, in order to join forces against the black robe, Yuwen Hu put down the pursuit of Mu Yi and gave him the Poison Dragon Secret Technique and the valuable Half-Grade Heavenly God Pill.

And now that the black robe has been killed, that Mu Yi is no longer of value to him. The only thing he was worried about was whether Mu Yi had really killed the black robe.

If the black robe is not dead, then killing Mu Yi is cutting himself off. The only one who can deal with Mu Yi is this Heavenly Spirit Secret Technique.

Mu Yi's expression was calm, he didn't threaten with force at the moment, he didn't know that his pyramid formation was no longer usable. Otherwise, now Yuwen Hu is not a threat, but directly kills him.

"I can tell you this, but you always go back on your word and have no credibility at all, so why should I believe your words!" Mu Yi said.

"Hahaha, do you want to get out like this? That's impossible! Now you only have two ways to choose, the first is to sacrifice your soul and submit to me, then you can leave here, and the second is to be trapped here forever, there are formations everywhere in this underground palace, even emperor-level powerhouses can't break through. Yuwen Hu shouted majestically.

"Then your formation can block the black robe?" Mu Yi laughed coldly.

"What are you talking about, the black robe is not dead?" Yuwen Hu was stunned for a moment, secretly surprised in his heart, is this black robe dead, now that the place is calm, if the black robe is still alive, will he let himself and Mu Yi go?

Could it be that the black robe is controlled by Mu Yi? That is even more impossible, Yuwen Hu will never believe that Mu Yi has such an ability. But at this moment, Yuwen Hu hesitated even more in his heart.

"Of course, the black robe is dead, but there is still a possibility of his resurrection. Mu Yi said with a smile.

Yuwen Hu looked at Mu Yi coldly, and regretted it in his heart, even if he succeeded in working with Mu Yi, he didn't have a sense of steadiness. It's not good, this time let Mu Yi enter this place to eliminate the black robe, and his threat was not contacted, but let Mu Yi have one more bargaining chip against him.

"Mu Yi, this is my underground palace, your Heavenly Spirit Secret Technique has no effect on the enchantment condensed by spiritual power, and you can't break these formations at all. Now I can relax the conditions, as long as you can hand over your memory and divine sense to me, you can get out of here without making any trouble, how about it?"

"Hmph, I'm still the same, your credit is too low!"

"This is what you brought on yourself, if the black robe is not dead, then I will face it after all, you have no threat. But now, you can't get out either!" said Yuwen Hu angrily.

When Mu Yi heard this, his body suddenly emitted a golden light, and all the relics in his body emitted golden light. Behind Mu Yi, the image of the deity of the relic, instantly condensed.

The breath of the Chongming relics spread to all sides, and the space around Mu Yi twisted and turned in an instant, and the golden light suddenly showed the appearance of a pyramid, at first glance, the breath of this formation and the original pyramid formation were completely based, reaching the point of being fake.

"It's this formation again!" Yuwen said secretly in his heart.

"Yuwen Hu, do you think I only have the top-level secret technique of the Heavenly Spirit Secret Technique? The black robe is now dead, and it won't trouble you! But if you still want to entangle, the matter of the black robe may not be. What if I fight you!" Mu Yi shouted.

"What about fighting with you!" This voice rippled in Yuwen Hu's ears, and he looked at Mu Yi with an extremely calm expression, and his heart was suspicious.

"Hmph, what an arrogant tone! Although your formation can protect yourself, you don't have the power to attack! Since you are so persistent, then General Ben will see how you break my formation. Yuwen Hu shouted, his figure flashed, and he had already flown away from the underground palace in an instant.

Outside the dungeon, Yuwen Hu's hands quickly pinched and chanted, and the formation of the dungeon fell in an instant, and one phantom array after another trapped Mu Yi in it.

"It's really just trapping me!" Mu Yi laughed between his mouths, "If you kill me directly, it will be very troublesome, but if you want to trap me, you are helping me!"

Mu Yi flew to the outer wall of the nearest formation, this formation was condensed by spiritual power, and his Heavenly Spirit Secret Technique was ineffective against such a formation.

But his methods are more than the Heavenly Spirit Secret Technique!

Mu Yi pinched the secret with one hand, and he chanted a secret mantra in his mouth. At the same time, Mu Yi pressed his palm on the inner wall of this formation, and the golden body of the Buddha in the sky turned into a spiritual light and injected into Mu Yi's body.

In an instant, Mu Yi's body flashed, and he had already appeared in the outer world of that formation, and he passed through this formation without waste.

"Hmm, this breath is ......" Mu Yi suddenly stopped, and he sensed a familiar aura flying rapidly from an extremely distant place.

"Why are they here?" Mu Yi said secretly in his heart, his divine sense had sensed that in the outside world, there were many familiar auras, flying towards this place.

"They are not Yuwen Go's opponents, and once they fight, they will definitely be hit hard, and they must be stopped as soon as possible. Mu Yi's heart suddenly became nervous, and he hurriedly sped up his speed and passed through the formations.

But in this underground palace, there are too many formations. It's no wonder that Yuwen Hu swore that the strong people who cultivated as emperors couldn't escape from here, and ordinary emperors might have exhausted their spiritual power before they could break through all the formations.

At the same time, high in the sky outside the dungeon.

At this moment, Yuwen Hu felt that Mu Yi's aura had been isolated by the formation. He waited for a while, not seeing anything unusual in the formation.

"The black robe didn't come out?" Yuwen Hu said secretly in his heart, and suddenly, Yuwen Hu was overjoyed in his heart, at this moment he had already concluded that Mu Yi was not in control of the black robe, and the black robe was indeed killed. Otherwise, Mu Yi himself would be trapped inside, and he wouldn't let the black robe go out to save him from the dungeon?!

"Hmph, this is what you asked for, your Heavenly Spirit Secret Technique is only useful for the spirit body, you are just a Heavenly Master cultivator, after a day, the effect of the half-grade Heavenly God Pill will disappear, but your mana is lost, so you will be obediently slept here!" Yuwen Hu laughed.

He turned around to fly away from the mansion, and at that moment, he suddenly felt a huge force rushing into the distance, but the power disappeared in a flash.

"Murderous?"

"This is the breath of an emperor-level powerhouse, and it's not just one person, who is that?" Yuwen Hu exclaimed, "Could it be Yuwen Yu's person?"

Yuwen Hu quickly sent out a divine thought, and the hidden masters in his mansion immediately flew out of the sky, these masters were the masters who were ambushed here in order to deal with Yuwen Yu.

Sure enough, not long after, a group of strong people secretly flew in the sky.

These powerhouses were all covered by a secret technique, and if it weren't for the rapid improvement of Yuwen Hu's cultivation now, he wouldn't have been able to detect the other party's aura at all.

"Who are you?" asked Yuwen Go, who quickly asked, finding that there were fifty people in the group, but the only one who cared about him was the one who led him.

That person's aura was very strange, and his cultivation was probably not below him.

"Mu Yi's breath is broken here?" The man at the head secretly said in his heart, he was the patriarch of the Rouran Clan, and behind him were all the masters of the Rouran Clan, as well as the White Dragon, Lianshuang and Fire Ape and others.

"Fire Ape, can you feel the breath of Mu Yi?" asked the white dragon quickly, and they didn't pay any attention to Yuwen Hu's question.

"Mu Yi is trapped in the underground palace below, and the formation in this underground palace is very strong....... ......Huh? Is that the figure of Makuyi?" Fire Ape exclaimed.

Under that dungeon, there were nearly a hundred formations, and each of them was extremely powerful. But at this time, the fire ape found that Mu Yi passed through one by one, and the speed was extremely fast.

"Hahaha, it turned out to be the ability of the Chongming Relic, the power of this Chongming Relic has become so strong, and the penetration of the advanced formation is also so neat!" the fire ape sighed with a smile in his heart.
