The two rat demons burrowed out of the ground, but the sight in front of them shocked them suddenly.

"Huh.......? What's going on!" The rat demon was completely stunned, they only saw all the guards lying on the ground, and Mu Yi's body exuded a thick black mist.

Each of these guards was killed, but they were hit hard, and they looked at Mu Yi with panicked expressions, and they didn't dare to speak. The rat demon looked at Mu Yi, and they felt a terrifying aura.

Mu Yi looked at the black mist on his hands, he also didn't understand, he was obviously suppressed just now, but his body was becoming more and more flexible, and he could even act independently.

In the battle just now, the speed of the leader was very fast, and his body couldn't keep up at all at first, but after a few moves, his movements were extremely fast under this black fog, and the guards at the moment were not enemies of one move.

In his previous life, he was really a strong monk?

Mu Yi suddenly changed his opinion of himself, how strong would it be? What kind of cultivation is the Heavenly Master? What kind of cultivation is the Emperor Master, what is the strength of Hu Luguang who killed him?

Mu Yi turned around and found that the two rat demons had come back again. It seems that they can't rest assured themselves, and he said with a warm smile in his heart, "You guys get out of here and wait for me outside!"

"You...... Do you really want to go inside?" the mouse demon immediately asked.

"That's right, I have to go in, there should be my acquaintances inside!" Mu Yi patiently replied, that familiar breath should be someone he knew, but he could feel that the person was also asleep.

Maybe when he saw that person, he should have regained some of his memories.

"Get out of here, thank you for taking care of you during this time, thank you very much!" Mu Yi bowed down and said to the two rat demons, who were stunned and didn't know what to say.

The rat demon hurriedly pulled the mouse demon who was still in a daze, and hurriedly left here.

They already understood that they were completely different from Mu Yi, they were not suitable for their peers, so it was better to leave it at that. Mu Yi watched the two rat demons leave here, and sighed a little in his heart, in this world, the rat demons would take care of him like this, and he felt warm in his heart.

Mu Yi turned around and flew quickly towards the ancient city.

"Wait...... You can't go in!" the leader of the guard struggled to his feet, and shouted with a very bitter expression, "the general will not see you, he has given an order, not to see anyone!

"He was like this before?" Mu Yi immediately asked.

"No, this order was given only the day before yesterday!" said the chief, suffocatingly.

"Hmph, it seems that this city is indeed a bit strange, and he gave the order, I am afraid it is also related to my friend. Mu Yi smiled in his heart, and he continued to walk forward.

The leader immediately rushed over, still stopping Mu Yi. But Mu Yi's palm wind slapped from his side, and the leader was instantly knocked out by Mu Yi, and he had already passed out.

Mu Yi jumped quickly, passing through this towering wall, and he suddenly found that his body was extremely strange, barely making any sound during his movements, and even the fluctuations in the air were minimal.

"Was I once a top-level killer?How high is my ability?" Mu Yi was surprised in his heart, although he couldn't control the power of the Xuan Ling, this inexplicable black qi was like the power of the Xuan Ling, and he could control it as he wanted.

Mu Yi's steps were brisk, and he quietly sneaked into this ancient city. The ancient city in front of me is extremely spacious, with countless large and small ancient cities in the city, and there is one of the tallest castles in the middle.

"This aura is getting stronger and stronger, who the hell is this? Who is mine?" Mu Yi pondered in his heart as he dived in.

"I was killed by Hu Luguang to save my lover, so my lover is also dead? So it's likely to be my lover in front?"

"Why is it a lover? instead of a wife? In my previous life, was I a person who was in the twilight?" Mu Yi's thoughts couldn't help but mess up.

"But no matter who it is, I should know some news after I see her!" Mu Yi's figure flashed, and he had already come to the periphery of this highest ancient city.

At this moment, his speed had unconsciously recovered to the speed of a one-star celestial master. Along the way, he found that there were more and more guards around him, and they were getting higher and higher.

Around this city, there are already many guards wearing gold armor or even another identity, and their strength is much stronger than the guard leaders outside the city.

But Mu Yi was a little different, and at this time, he almost effortlessly infiltrated the heart of this ancient city, which was too easy.

This general is a famous general under the king of Hades, and it stands to reason that he should be guarded by heavy troops.

"This underworld seems to be a little different, but after entering it, you should know everything. Mu Yi flew up and flew straight to the height of this ancient city.

The ancient city is hundreds of zhang high, like an attic, and each floor is patrolled by a large number of guards. However, Mu Yi flew in the air, rushed out of the field of vision of these guards, and flew down to the inside of the attic on the highest floor.

In this attic, there are more than a dozen guards. Mu Yi's figure flashed, and he flew directly through the blind spot of these guards' vision and came to the interior of the attic.

In this attic, there were no formations, runes, etc. at all.

In the center of this pavilion, a huge tiger demon was sleeping on a long bed, and suddenly he opened his eyes suddenly, as if sensing a strange aura.

"What people!" the tiger demon immediately woke up and picked up a long knife from the stand next to him, and the servants around him were suddenly terrified.

"General, what do you command?" shouted in an instant, a dozen guards immediately flew over.

"Rubbish, the attic has been burglarized, you don't know yet! search for me!" the general shouted immediately.

"A thief?" More than a dozen guards looked at each other with surprise, they hurriedly retreated, and all the guards began to search for each other with all their might! For a while, the entire city suddenly became agitated, and almost all the guards reacted quickly.

"I've been discovered?" Mu Yi immediately noticed the unusual movement outside, he sped up and flew quickly in the direction where the feeling came from.

After passing through the wooden doors and flying past the heavy guards, Mu Yi finally came to a dimly lit secret room. In this secret room, Mu Yi felt that the aura was extremely strong. The other party seemed to be asleep, but the aura he exuded was indeed calling him constantly.

"Who could it be?" Mu Yi suddenly felt another nervous feeling in his heart, he walked quickly, it was already pitch black in front of him, and it was extremely cold, but Mu Yi's body automatically condensed a black aura, and he could see everything around him clearly in the dark.

Not far ahead, there was a huge crystal stone standing, Mu Yi walked in quickly, and this crystal stone was covered by black mist.

His right palm was gently pressed on this crystal stone, and suddenly, all the black mist on the crystal stone instantly poured into his body, and the figure in the crystal stone suddenly appeared in his eyes.

Inside was an ape, more precisely, an ape monster, covered in fiery hair.

"Ape ........ Fire........ Fire Ape?" Mu Yi suddenly shouted, a chaotic stream of information frantically poured into his mind, and in front of him was a five or six feet tall Fire Ape, with hair floating like flames, and his eyes were still slightly closed.

"Fire Ape, that's right, this is my spirit beast Fire Ape!How could it be here, is it already dead?" Mu Yi exclaimed in his heart.

But at this moment, Mu Yi's back instantly sensed a cold murderous aura, he flashed rapidly, and a knife light slashed past him.

"Who are you, you dare to break into this place!" The person who came was the Tiger Demon, who was holding a long knife in both hands, and his eyes were glaring at Mu Yi.

"You caught it?" Mu Yi's eyes were full of anger, and he also exuded a fierce murderous aura on his body.

"Hmm, you're just a geist, no way, how could a geist wake up, what the hell are you?" the tiger demon asked in surprise.

"Let it go, you will definitely know what you should know!" Mu Yi snorted coldly, and it finally understood that the reason why this tiger demon blocked the ancient city should be to capture the Dao Fire Ape.

And the fire ape also entered this world with him.

"It, do you recognize it?" the tiger demon asked in surprise, seeing Mu Yi's anger, it frowned, thinking in the bottom of its heart, Mu Yi's reaction made him hesitate a little.

"He's my friend, of course I know!He's not here, I'm going to take him!" Mu Yi said again.

"Of course he doesn't belong here, but why should General Ben believe you!" exclaimed the Tiger Demon.

"I can't help you not believe it, it's my people, I must take it away!"

"You're a geist, if I'm not mistaken, he entered the underworld because you were killed, right? You can't even protect him, and you still want to take him?" said the tiger demon angrily.

Mu Yi was a little surprised when he heard this, this tiger demon seemed to be a little concerned about the fire ape, could it be that he knew the fire ape?

"The fire ape doesn't know you, why did you seal him here!" Mu Yi immediately asked.

"General Ben is indeed ignorant of him, but the Fire Ape Clan, an ancient divine beast, used to be the leader of my Tiger Demon Clan! Since he is a Fire Ape Clan, General Ben will protect him!"

"Protection, sealing him inside the crystal stone is protection!" Mu Yi laughed coldly.

"He is different from you, although I don't know why you woke up, but he is a spirit beast, and the dark qi here is harmful to him, and General Ben has to seal him!"

"Hmph, I see, I really have evil intentions!" Mu Yi's eyes burst out with a murderous aura, and he rushed out instantly, condensing the black qi sword with his two fingers, and immediately slashed out from behind the tiger demon.

"It's ....... Is this the aura of the Xuan Netherworld?" the tiger demon flashed quickly, but he was completely stunned when he saw the black mist bursting out of Mu Yi's fingers.

"Xuan Ming Qi, this black Qi turned out to be Xuan Ming Qi!" Mu Yi said secretly in his heart.

"Who the hell are you, how can you have the aura of the underworld?" the tiger demon exclaimed, but Mu Yi didn't reply, and still rushed to kill.
