"Why are you here? Miaomiao?" Nie Lan was a little surprised when she saw him coming.

"It's at home," Luo Yan smiled. Seeing that there was no one in the room, he took out the small bottle that Xie Xiaoyuan brought.

"You can help me see what this is useful."

The bottle is very simple and you can get it casually at first glance.

Nie Lan glanced at Luo Yan and saw that he had a serious expression, she knew that this matter must be very serious for him.

She took it directly to the laboratory next to her.

Luo Yan followed him to the door and was stopped by Nie Lan.

Luo Yan smiled and turned to the corridor to have tea.

After about an hour, Nie Lan came out of the laboratory with some fatigue.

"Where did you get this?"

"A friend gave it to you," Luo Yan said.

"What are you going to do?"

Nie Lan asked seriously.

"What's wrong?"

Luo Yan asked her.

"This is a chemical that eliminates toxic gases, but when it is eliminated, a large amount of toxins will be produced."

“It can be fatal if you don’t pay attention.”

Luo Yan was a little moved.

Seeing that he was like this, Nie Lan knew that he didn't know.

"But if ventilation is good, the odor and toxins will disappear after two days."

“Will it not remain?”

Luo Yan asked.
