In the following period, Yue Hao, Jiu Lao Ren, and A Xiu all started complex calculations in the cave.

Yue Hao also ordered Quanteng to take three werewolfs to forbid anyone from entering their cave.

When the old man Jiu and A Xiu joined forces to calculate the complex formation, Yue Hao immediately outlined the magic array on the stone wall.

Now the old man Jiu is in poor health, but he is still continually deducing.

"Actually, the magic circles of the underground black prison are not extremely complicated! The Holy Sect Presbyterians like to suppress everything with powerful power! They like to suppress enemies with pure power rather than exquisite skills." The old man Jiu said while calculating.

After nearly a month of calculation, they finally calculated that there were some loopholes in the magic circle group of the underground black prison.

"The power of the magic array group of the underground black prison will become weaker and weaker, and then the superpowered people of the underground black prison, especially those of the holy realm superpowered people, will quickly restore their strength." After a long time, the old man Jiu suddenly said excitedly.

Yue Hao and A Xiu looked at each other and were very happy.

"Master, I've sent out to monitor the soul masters' confidants for several times!" Half an hour later, Wright suddenly appeared, and he reported to Yue Hao with anger.

"How did they die?" Yue Hao thought for a while and asked sternly.

"I just received the news that those people were killed by the power of darkness!" Wright said quickly.

"Only those who can condense dark power into entities and then kill opponents can only achieve the dark attribute superpowers who have the cultivation level of the holy realm. But now the underground black prison does not have dark attribute strong people in the holy realm." The old man Jiu suddenly murmured.

"Grandpa, what you said is wrong. The king of the underground black prison is the dark superpower in the holy realm." A Xiu quickly retorted.

"Old sir, A Xiu is right! The king of the underground black prison is indeed good at dark power!" Yue Hao immediately echoed.

"I felt very strange when the underground king of black prison died. It turned out to be a charred body. Only a reckless man like Black Tiger would believe that he was really dead!" Old Man Jiu thought about it, and suddenly smiled and said.

"Wright, from now on, we must be careful. You should notify your father in person and tell him to be careful. Also, you should send more little demons and cavemen out immediately and let them walk around. If you find that someone abnormal appears, come back and report immediately." Yue Hao and the old man with the wine discussed it, and then ordered loudly.

Wright quickly agreed and ran out.

"Old sir, I'll go out for a walk. You have to stare at Axiu. Last time she secretly ran to the sea of ​​abyss, and was almost eaten by a demon clan!" Soon Yue Hao suddenly glanced at the old man with wine and said.

"Yue Hao, why did you tell my grandfather this secret?" A Xiu's face suddenly turned red. She waved her fist to Yue Hao with some anger and said loudly.

"Axiu! I must have a good talk with you!" Old Man Jiu's face changed suddenly and he immediately said sternly.

"Boss Heihu, please summon all your brothers immediately. We seem to be in big trouble!" Yue Hao quickly found Heihu and whispered.

Heihu was shocked and nodded quickly to agree.

A few days later, under the leadership of Wright, Yue Hao saw the bodies of the killed demon men.

The faces of these people were full of fear, their bodies were twisted, and black blood flowed out of their wounds from time to time.

Yue Hao used his powerful soul power with all his strength. After a quarter of an hour, he finally found a trace of darkness from the bodies.

Those corpses were once high-level superpowered warriors of the demon race with strong combat power, but their fearful appearance before their deaths shows that the opponent is likely to be a powerful saint realm.

Soon Yue Hao trembled all over. It turned out that when he suddenly discovered that the men of the demon clan were killed, someone forced their souls away.

"That sneak attacker is really cautious!" Yue Hao murmured in anger.

The other party was obviously a very experienced killer, and he left no clues.

With Yue Hao's current soul power, he can extract some of the scenes he saw before his death from the remaining soul aura of the dead, but the other party instantly took away all the souls of the dead, so Yue Hao could not find anything useful from them at all.

However, he still smelled a faint smell of sulfur. It was the smell of sulfur mixed with blood and a smell of dark and frenzied.

Yue Hao thought for a long time and couldn't help but frown. He found that this scent of sulfur may not exist in the underground black prison, and that the murderer came from the outside world.

Suddenly, Yue Hao suddenly felt a slight change in the air behind him. Because his soul power was very strong, he could feel the subtle fluctuations of the air and sensed all things that could not be touched by the senses.

In an instant, he was shocked and found that behind him, a powerful existence was approaching quietly.

The powerful being silent, emitting no smell or making any movement, was even more weird than a ghost.

However, because he shuttled through high speed, he still caused a slight fluctuation of air, which made Yue Hao's soul power feel.

Three seconds later, Yue Hao suddenly turned around and his right hand changed into a flame knife, slashing hard in that direction.

In an instant, he saw that powerful existence, a lizard man.

The lizardman was covered with scales, and even his face had many scales. He had green horns on his head, about 1.7 meters tall, thin, and a crazy bloodthirsty light flashed in his eyes.

His hands were like dragon claws, extremely sharp. With a light wave, ten cold lights shot towards Yue Hao's ten vital points like lightning.

But Yue Hao's flame sword was faster. When the ten cold lights were three feet away from Yue Hao, the flame sword slashed through the lizardman's body and immediately cut him off in half.

But the life force of the lizard man was very terrifying. He was still alive, and he gritted his teeth and let out a scream. He opened his mouth and spewed out a red flame mixed with the smell of strong sulfur.

Rumble!

Yue Hao smiled coldly, and a fireball immediately condensed in his left hand, and then the fireball rushed out like a meteor, and instantly bombarded the red flame.

The red flame was immediately exploded, and then some flame fragments splashed onto the surrounding stone walls.

The power of the red flame is very terrifying. The splashing flame fragments are actually burning on the stone wall, causing the stone fort there to melt a large area.

But no flame fragment could approach Yue Hao's body. A dragon-shaped protective cover had already surged out of his body. Those flame fragments could not break the protective cover at all.
