Xu Mu frowned slightly, his mind working rapidly, and in a moment, he understood what had happened.

If nothing unexpected happens, this formation is the same as the sword technique he just performed, which is a mental attack.

Generally speaking, this kind of formation is difficult to resist. After all, the body's defense can be enhanced through exercise.

Mental defense is not so easy.

But with Xu Mu's powerful mental power of more than a thousand, this formation had no effect on him at all.

The guards over there were already enjoying themselves and were being teased by these women.

The women each pulled one person and headed towards a distant room.

"My dear, why are you ignoring me?"

The woman next to Xu Mu continued to speak.

"Hey, I have a secret that I've been hiding in my heart. Don't look at me as strong, I'm actually not ugly."

Xu Mu sighed deeply.

As he spoke, he used his senses to check his surroundings.

Although the interior of the formation is winding and affects the range of perception, the building is not large and can still be covered by his perception.

In the room far away, more than a dozen guards were already bewitched and had taken off all their clothes.

And these women also lay on top of them.

Just as they were enjoying themselves, the women's fingers, transformed into sharp blades, instantly pierced their heads.

Their movements were so uniform that it could be said that they all died almost at the same time.

After their death, the bodies of these women turned into patterns of the magic array and slowly dissipated.

At this moment, Xu Mu discovered that Zi Wangyou walked out from another door, and with her was a middle-aged man with half-shaved hair.

They took out bottles of medicine and poured them on the corpses.

In the blink of an eye, all the corpses were devoured and disappeared.

Seeing this, Xu Mu was certain that this Zi Wangyou must have something going on, secretly planning something without telling the Institute of Eternal Life.

Otherwise, how could she possibly kill all of her own people?

"Miss, those two men seemed to still have some consciousness. I didn't expect them to be able to withstand the mental attack of the eighth-level formation."

Liu Ge's voice reached Xu Mu's ears.

"These two people are indeed extraordinary. They must be geniuses trained by the Institute of Eternal Life."

Zi Wangyou said in a deep voice, "It seems that I have really been exposed."

"No, we've got quite a few treasures in these fish anyway."

Liu Ge waved his hand indifferently.

"I just don't understand where I went wrong. I've never neglected any of the tasks assigned to me by the Institute of Eternal Life."

Zi Wangyou frowned, "When they robbed the treasure from the Eternal Life Research Institute, we wiped them out completely, leaving no trace. How did they find out it was us?"

Xu Mu was entangled with the woman beside him at this time, sighing.

What I said really came true. I didn't expect that Zi Wangyou would kill all the members of the Eternal Life Research Institute and steal their treasures.

If that's the case, this woman is still one of the same kind.

Liu Ge shook his head. He was able to enter the Institute of Eternal Life with the help of Zi Wangyou.

Zi Wangyou's status was much higher than his, and she didn't know it, so how could he know it?

"Miss, let's talk about these two people first. How should we deal with them?"

Liu Ge asked.

"What else can we do? They must have been killed. Although the mental attack of the formation couldn't completely trap them, they must have been affected. It must have had an impact."

After Zi Wangyou finished speaking, he re-entered the room over there.

The next moment, she appeared from the door behind Xu Mu and approached Xu Mu step by step.

At this moment, Xu Mu suddenly pushed the woman beside him away, and he stood up and said, "I'm sorry! I'm really not feeling well!"

After finishing speaking, Xu Mu looked at Zi Wangyou behind him.

Zi Wangyou frowned, then smiled broadly, "My dear, this is my sister. Am I not entertaining you well enough?"

She sneered in her heart, thinking that the mental attack of this formation would make people reveal their hypocrisy.
