As for what exactly is going to be done for half an hour, I'm afraid this can only be known by His Highness the Hades King, who is smiling like a successful steal.

At this time, Nalan Mansion was the time when the dinner was staggered and lively, and Nalan Zhengze was of course feasting in the front hall.

However, Nalan Zhengze did not relax the guards of the study.

Even, compared to normal days, there seemed to be twice as many guards patrolling around the study at this time.

However, the guards of Nalan Mansion are of course just a piece of cake for Suxi and Nangong Yu.

Moments later, however, the guards were all on the ground, sleeping like dead pigs.

Su Xi took out the silver needle, pricked the heads of these guards a few times, and asked Nangong Yu to help them up and maintain a standing posture.

"After a little more incense, they will wake up, but they don't remember anything that happened."

Su Xi took back the silver needle and chuckled: "So even if someone comes to this study halfway, they won't find anything unusual." ”

Such a technique of controlling people's memory and perception in a short period of time is not uncommon in the immortal cultivation world, but it is absolutely impossible to achieve it as easily as Suxi.

The girl in front of her, in the field of medical skills, seems to have reached the pinnacle, and she has never seen anything that can really stump her.

Nangong Yu lowered his eyebrows, covering the pampering and burning desire in his eyes, and the corners of his mouth hooked up a gentle smile.

If such a stream blooms one day, it will definitely become an existence that many people covet and desire, right?

However, no matter how much those people covet it, it is useless, because he will definitely keep Suxi firmly by his side.

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

As soon as he entered the room, he almost didn't need Suxi's guidance, and Nangong Yu's gaze fell on one of the corners of the study.

Seeing Nangong Yu walking in that direction, Su Xi immediately grabbed his hand, "This formation is very weird, as long as you get a little closer, it seems that Nalan Zhengze will feel something, even if it is something that does not have spiritual power fluctuations, it is no exception." ”

Nangong Yu smiled slightly, grabbed Suxi's soft little hand with his backhand, and pulled her to take a step forward.

Just as he was about to approach the array sensing range, Nangong Yu paused, and a unique magic seal formed in his hand.

Then, a pure black spiritual power spread from his fingertips, spreading to every corner of the room.

With the pervasiveness of pure black spiritual power, the feeling of being as if watching their every move disappeared in an instant.

It is also a strange and powerful formation in front of him, but Su Xi just has a feeling that no matter what they do next, Nalan Zhengze will not sense it again.

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

Nangong Yu scratched the tip of her nose and smiled ostentatiously: "Now you find out how powerful your man is?" ”

Su Xi's mouth was open for a long time, and he didn't even react to refute Nangong Yu's teasing.

Because, the dark is the spiritual power...... It's amazing!

Suxi remembered that there was a record in the old man Sumeru's record of all things that there were many powerful forces in nature, wind, rain, thunder, lightning, frost, but these powers, in the final analysis, were mutated from the five elements of the origin of gold, wood, water, fire, and earth.

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