As for what exactly the preparations took half an hour, perhaps only His Majesty the Pluto, who was smiling as if he had succeeded in stealing something, would know.
At this time, the Nalan Mansion was in the midst of a lively dinner, and Nalan Zhengze was of course entertaining the guests in the front hall.
However, Nalan Zhengze did not relax at all in guarding the study.
In fact, there seemed to be twice as many guards patrolling around the study as usual.
However, the guards of the Nalan Mansion were of course a piece of cake for He Xi and Nangong Yu.
But after a while, all the guards fell to the ground and slept like dead pigs.
He Xi took out a silver needle and pricked the heads of these guards several times, then asked Nangong Yu to help them up and keep them standing.
"After an incense stick of time, they will wake up, but they will have no memory of what happened."
He Xi took back the silver needle and chuckled, "So even if someone came to this study during this time, they wouldn't notice anything unusual."
This method of controlling a person's memory and perception in such a short period of time does exist in the world of immortal cultivation, but none of them can do it as easily as He Xi.
The girl in front of him seemed to have reached the pinnacle in the field of medicine, and there was nothing that could really stump her.
Nangong Yu lowered his eyebrows to hide the doting and burning desire in his eyes, and a gentle smile appeared at the corner of his mouth.
If a Xier like this could shine brightly one day, she would surely become the one coveted and desired by many people, right
However, no matter how much those people covet, it is useless because he will definitely keep He Xi firmly by his side.
After dealing with the guards, the two quickly entered the study.
As soon as he entered the room, Nangong Yu's eyes fell on one corner of the study without any guidance from He Xi.
Seeing Nangong Yu walking in that direction, He Xi immediately grabbed his hand and said, "This formation is very strange. As long as you get a little closer, it seems that Nalan Zhengze will be able to sense it, even if it is something without spiritual power fluctuations."
Nangong Yu smiled slightly, took He Xi's soft little hand in his backhand, and pulled her forward a step.
Just as he was about to approach the sensing range of the formation, Nangong Yu paused and formed a unique seal with his hands.
Then, a pure black spiritual power spread from his fingertips and diffused to every corner of the room.
As the pure black spiritual energy spread, the vague feeling of being watched over their every move disappeared instantly.
It was the same strange and powerful formation in front of them, but He Xi had a feeling that no matter what they did next, Nalan Zhengze would no longer be able to sense it.
She looked at the black spiritual power that had dissipated into the air, and couldn't help but open her mouth wide and exclaimed: "Dark spiritual power?"
Nangong Yu scratched the tip of her nose and said with a boastful smile: "Now you realize how powerful your man is?"
He Xi opened his mouth for a long time and didn't even react to refute Nangong Yu's teasing.
Because, the dark spiritual power... is really too powerful!
Hexi remembered that it was recorded in the Record of All Things by Old Man Xumi that there were many powerful forces in nature, such as wind, rain, thunder, lightning, ice and frost, but these forces, in the final analysis, were the variations of the five elements: gold, wood, water, fire and earth.
Therefore, the most powerful thing in the world is the power of the five elements. The purer the basic five elements spiritual power, the stronger it is. (To be continued)
