As for what is going to be prepared for half an hour, this is probably only known to His Royal Highness, the Hades who smiled like a successful stealth.

At this time, Nalan Mansion was a time when the dinner was co-planned and lively. Nalan Zhengze was of course feasting in the lobby.

However, Nalan Zhengze did not relax at all in guarding the study.

Even more, the guards patrolling around the study room at this time seem to have doubled compared to normal days.

However, the escort in the district of Nalan, for Suxi and Nangong Yu, is of course a piece of cake.

But after a while, these guards fell to the ground and slept like dead pigs.

Suxi took out the silver needle and pierced the heads of these guards a few times, and asked Nangong Yu to support them and maintain a standing posture.

"Another incense time, they will wake up, but do not remember what happened."

Suxi withdrew the silver needle and chuckled: "So even if someone came to this study halfway, he wouldn't find anything unusual."

Such a short time to control people's memory and perception, Xiuxianjie is not without, but it can never be as easy as Suxi.

The girl in front of me seemed to have reached the pinnacle in the field of medicine, and I never saw anything that could really upset her.

Nangong Yu lowered her eyebrows to hide the spoiled and burning desire in her eyes, and a soft smile was raised at the corner of her mouth.

Such a stream, if one day shines with tremendous light, it will surely become the coveted and longing existence of many people, right?

However, no matter how coveted those people are, it is useless, because he will surely guard Suxi by his side.

After dealing with the guards, the two quickly entered the study.

As soon as he entered the room, he didn't need Suxi's guidance. Nang Gongyu's eyes fell on one of the study's corners.

Seeing Nangong Yu walking in that direction, Suxi immediately grabbed his hand, "This formation is very strange, as long as it is a little closer, it seems that Nalan Zhengze will feel it, even if there is no spiritual fluctuations, No exception."

Nangong Yu smiled slightly, holding back the soft little hand of Suxi, and took her a step forward.

Immediately as he approached the range sensing range, Nangong Yu stepped in and formed a unique seal.

Then, a pure black spirit spread from his fingertips and spread to every corner of the room.

As the pure black spiritual power diffused, the sensation of seemingly monitoring their every move disappeared instantly.

It is also a strange and powerful formation in front of him, but Suxi has a feeling that no matter what they do next, Nalan Zhengze will no longer feel it.

She looked at the black spiritual power that had dissipated in the air and couldn't help but open her mouth and exclaimed, "Dark spiritual power?"

Nangong Yu scraped the tip of her nose and laughed like a show: "Now find you a good man?"

Suxi's mouth opened for a long time, and he didn't even react to refute Nangong Yu's play.

Because, the spiritual power of the dark... is really amazing!

Puxi remembered that there were records in the records of the old man Xu Mi. There are many powerful forces in nature, wind, rain, thunder, lightning, frost, but these forces, in the final analysis, are derived from the variation of the five elements.

Therefore, the most powerful thing between heaven and earth is the power of the five elements. The more pure the basic spiritual power of the five elements, the more powerful.
