Thrilling voices echoed from all around, attacking the souls of everyone. After seeing this scene, Xiao Wuji frowned because he knew that if the will of these human monks were broken, it would be very difficult to defeat the Shadow Demon Lord and the Nether Demon Lord. At this time, the Nether Demon Lord's Nether power turned into a huge black shadow. Under his control, countless demons and monsters attacked the human monks. They were all in and were like shadows, and were very difficult to get rid of them like maggots attached to bones.

Seeing this scene, Xiao Wuji immediately released the divine power in his Niwan Palace. The mysterious power of the sixth level surged out from Xiao Wuji's body like a tide and swept directly away.

In Xiao Wuji's divine mind power, there was a trace of golden power, as if it could illuminate the darkness. Under Xiao Wuji's will, those divine mind power turned into golden swords and slashed towards the ghosts and monsters.

Under Xiao Wuji's crazy attack, the ghosts and monsters disappeared and the darkness was also cut through, revealing a trace of light. At this moment, many human cultivators' confidence increased greatly. On the contrary, the faces of the Shadow Demon Lord and the Nether Demon Lord were very ugly.

"Why is this guy's divine power so powerful?

Damn, this time he really ruined our big deal.”

The Shadow Demon Lord and the Nether Demon Lord wished to cut Xiao Wuji into pieces, but they also realized that it was not easy to defeat Xiao Wuji now.

Then they looked at each other and said, "It seems that only one person has been invited out."

They bit through the tip of their tongues, and their blood soared out, gathered in the void, turning into an ancient mark. Then Xiao Wuji felt an indescribable wave of energy and immediately dissipated. When he saw the ancient mark dissipated, Xiao Wuji's heart skipped a beat.

Because he realized that the next thing would be troublesome. Perhaps there were even more powerful demons guarding this Great Cloud Underground Palace. No matter what, since he had already arrived here, even if there were jackals, tigers and leopards in front of him, he would not retreat at all.

Then the two sides started a fight again, but this time the Shadow Demon Lord and the Nether Demon Lord seemed to have exhausted their strength. They usually ended up with about one stick of incense and then completely defeated. They also had a silver key on their bodies. The key on them was not exactly the same as the one on Xiao Wuji's hand.

These two silver keys were obtained by a man and a woman respectively. The woman's name was Qiao Yixuan, with a beautiful and beautiful face, very fair skin, and a tall figure. As for the man's name, Sheng Tianlei, his body was very burly and tall, but the aura he released was also very strong, at least reaching the peak of the ninth level of the Martial Emperor's Ninth Heaven, and one more step can reach the level of the Martial Emperor's level of the Martial Emperor level.

As for the other monks who did not get the silver key, they also looked regretful, but they also saw that Xiao Wuji, Sheng Tianlei, and Qiao Yixuan were very strong. It was impossible to snatch the silver key from their hands.

"As far as I know, what is truly valuable in this Great Cloud Underground Palace is not those treasures, but a alien energy."

At this time, Sheng Tianlei spoke and said to Xiao Wuji and Qiao Yixuan.

His words were not concealed at all, and all the monks around him heard it. However, Sheng Tianlei has this kind of personality. His strength is strong, so he is not afraid that others will have any covetousness towards him. Moreover, the sect behind him is a powerful force in the land of Zhongzhou. If anyone dares to make up for his ideas, he will be alive.

At this time, Xiao Wuji also raised his eyebrows, and his eyes fell on Sheng Tianlei.

You must know that it was through the golden villain and his own perception that he learned that there was the origin of the nirvana vital energy in the Great Cloud Underground Palace, but this Shengtian Thunder also knew this news. If his own perception ability was excluded, it was probably the force behind him who found out the news.

As for Qiao Yixuan, she didn't seem to know much about the news of the nirvana.

But no matter what, these two people must be Xiao Wuji's competitors. Both of them are not weak. If these two guys join forces, even Xiao Wuji will feel very difficult. But they have reached this point, and even if they are troubled, they will definitely not retreat.

At this time, Qiao Yixuan blinked, looked at Sheng Tianlei, and said, "How precious and rare alien energy is? How could it be so easy for us to meet? I think we should find a way to find all the treasures in the Great Cloud Underground Palace. This is the right way.

Besides, even if we find the alien energy, we can do nothing.

It is said that something is extremely dangerous."

When talking about the treasure, a fiery light appeared in Qiao Yixuan's eyes.

Sheng Tianlei pondered for a moment, then he said, "As far as I know, only these three keys can open the treasure inside."

After saying that, Sheng Tianlei took out an ancient copper plate from his storage ring, and then he dripped a drop of his essence and blood into the copper plate.

Suddenly, a huge light burst out, and then an ancient iron door appeared in front of everyone, and there were three holes on the iron door.

At this time, Sheng Tianlei spoke, "As long as we put these three underground palace keys in, we can open it, but other people can't get in at all."

After hearing this, the monks who were waiting outside and wanted to pick up some cheap things showed disappointment on their faces, but they did not leave. These people came here after a lot of hardships and were about to get the treasure. Who would be willing to leave empty-handed?

Then Xiao Wuji, Sheng Tianlei, Qiao Yixuan looked at each other, inserted the silver key in his hand into the iron gate of the underground palace, and suddenly rays of light burst out, dragging the three of them into it, and then the figures of the three disappeared completely here.

After seeing this scene, the monks outside the door looked at each other, looking very unwilling, because after the light was released, they swept the bodies of Xiao Wuji and the other two into it. Then the ancient iron door closed again, and even if they wanted to go in, they would not have a chance.

At this time, a monk rubbed his palms and said, "I'll give it a try and see if I can use brute force to blow the door open."
