Chapter 716

As for what to prepare for half an hour, I am afraid that only His Royal Highness Hades, who laughed like a sneaky success, would know.

At this time, Nalan Mansion was the time when the banquets were intertwined and lively, and Nalan Zhengze was of course banqueting the guests in the front hall.

However, Nalan Zhengze's guarding the study was not at all slack.

Even, compared to usual, the number of guards patrolling around the study seemed to be doubled at this time.

However, for Hexi and Nangong Yu, the guards of the mere Nalan Mansion were of course just a piece of cake.

But after a while, the guards fell to the ground, sleeping like dead pigs.

Hexi took out the silver needle and stabbed the guards' heads a few times, and asked Nangong Yu to help them up and maintain a standing posture.

"After another stick of incense, they will wake up, but they don't remember what happened."

Hexi took back the silver needle and said with a chuckle, "So even if someone came to the study in the middle of this, they wouldn't notice anything unusual."

Such a short-term method of controlling people's memory and perception is not without the immortal world, but it is absolutely impossible to do it as easily as Hexi.

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

Nangong Yu lowered his brows and eyes, hiding the doting and burning desire in his eyes, and a gentle smile appeared on the corner of his mouth.

If a stream like this blooms one day, it will surely become an existence that many people covet and long for, right?

However, no matter how much those people coveted it, it was useless, because he would definitely guard Hexi by his side.

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

As soon as he entered the room, there was almost no need for Hexi's guidance, and Nangong Yu's gaze fell on one of the corners of the study.

Seeing Nangong Yu walking in that direction, Hexi immediately grabbed his hand, "This formation is very strange, as long as you get close to a little, it seems that Nalan Zhengze will feel it, even if there is no spiritual power fluctuation, No exception."

Nangong Yu smiled slightly, took Hexi's soft little hand back, and took her a step forward.

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

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

With the permeation of pure black spiritual power, the feeling that seemed to be watching their every move disappeared instantly.

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

Looking at the black spiritual power that had dissipated in the air, she couldn't help opening her mouth and exclaimed, "Darkness spiritual power?"

Nangong Yu scratched the tip of her nose and said with a condescending smile, "Now you've found out that your man is amazing?"

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

Because, the dark-type spiritual power... is really amazing!

Hexi remembered that it was recorded in Elder Xumi's record of all things that there are many powerful forces in nature, such as wind, rain, thunder, lightning, frost, and frost, but in the final analysis, these forces are derived from the mutation of the five elements, gold, wood, water, fire, and soil.

Therefore, the most powerful thing in the world is the power of the five elements. The purer the basic five elements, the more powerful it is.
