Ao Yanran looked at Su Mengxi with a serious expression, "Xi, no matter how strong you are, don't use this sealing technique!" He was nervous, worried that Su Mengxi would use this sealing technique out of curiosity.

Su Mengxi tilted her head, "Why?" "Even though I'm wearing a human skin mask, it's still cute.

"Someone once used this sealing technique, and after using it, his strength has increased greatly." When Ao Yanran said this, his expression was even more solemn, so that Su Mengxi had to face up to what he said.

"But in less than ten days, the person who uses it will die a tragic death!" Ao Yanran stared at Su Mengxi with straight eyes, afraid that she would do something.

Su Mengxi bit her fingers, thinking about something, she whispered silently: "I, want, to, know, your, secret. What、 else、 is、 there 、behind 、you?”

(Translation: I want to know your secrets, what else is behind your back, what else is there that you can't see?) ）

She habitually bites her fingers, and she likes to bite her fingers every time she encounters something that confuses her.

Until now, she hadn't figured out why the Dream Phoenix Sword appeared.

Everything about the sealing technique came into Su Mengxi's mind.

Ao Yanran was still talking to Su Mengxi about this formation, "It must not be used easily, this formation is called ......" Without waiting for Ao Yanran to finish speaking, Su Mengxi smiled slightly.

"It's called silicon."

The smile on the corner of Su Mengxi's mouth was not because she was happy, she couldn't hold back her laughter.

What the? What are you laughing at?

As a genius girl from the modern age, uh no, a genius girl.

As a genius girl from modern times, she deeply understands what silica dust is.

Silica dust is an inorganic dust with a crystalline free silica content of more than 10%, silica dust is mainly inhaled into the lungs through the respiratory tract, causing harm to the human body, and the occupational disease that can be caused is called silicosis.

Long-term inhalation of high concentrations of dust can cause diseases mainly caused by fibrosis of lung tissue. Shortness of breath, chest tightness, chest pain, cough, hypoventilation, etc.

Now, this thing has become a formation name...... Sometimes you don't have to endure so hard if you know less. Alas ┑ ( ̄Д ̄) ┍.

Ao Yanran looked at Su Mengxi with a little surprise in his eyes, "How do you know?" "He didn't know until he had a lot of energy.

I remember that he had found it from the highest level of the Sealer's Branch.

Each branch has its own library, but the highest level is a forbidden area, no one dares to go to it, and no one can go there.

Ao Yanran also found it secretly, but how did Xi know? He didn't understand.

Su Mengxi shrugged, "How do you know, I know." "Perfectly kicked the ball to him.

Ao Yanran didn't think much about it, Su Mengxi's mystery was really not something they could see through.

As a sealer, he can also be regarded as a modern psychiatrist. He had tried to see something in Su Mengxi's eyes, but as a result, it was clear. The black cunning that Su Mengxi showed before could never be clear, but he didn't understand anything.

If he really looked at Su Mengxi's eyes, he felt that he would be lost in them.

The amber eyes are bottomless, as if you will never get out if you fall into them. But as long as she wanted, those deep eyes would be clear in an instant.
