"What's wrong?" Danqing asked, and Yeyue also looked at her. All the cloths Xi'er asked her to sew have been sewn exactly as required.
Xi'er looked at Yeyue, "Do we have any black cotton?"
Yeyue raised her eyebrows, and Xi'er continued: "We have to prepare one for Shadow. Of course he has to use a black one."
Yeyue remained silent, just looking at Xi'er. Then, she suddenly stood up, reached out and took out a piece of black clothes from a dark cabinet on the top, picked up the arrow knife, made a click, cut off a sleeve and handed it over.
Come to Xi'er.
Xi'er took it and continued to make masks with Yeyue. Xi'er was responsible for filling the activated carbon and Yeyue was responsible for sewing. In less than half an hour, they had made five. "Come on, Uncle Dan, try it."
"
"How to try?" Danqing took the "mask" uneasily and looked at Xi'er with a worried look, fearing that she would ask him to eat it. But he had seen that Xi'er dared to let people eat anything.
Mo... Xi'er reached out and took the mask over, tied it up for him, and tied two knots at the back of his head.
"Are you bored?"
Danqing took a few breaths and said, "It's not boring. But, what's the use of this?" It's not suspicion, it's just curiosity.
Xi'er smiled proudly and took off the mask for Danqing, "This is for passing through Tiger Roaring Valley." Seeing that Danqing was still confused, Yeyue also stared at her closely, so she had to explain: "Here,
The activated carbon I just installed can not only absorb poisons in the intestines, but also absorb poisons in the air."
After a pause, he said what he was confused about, "I suspect that the First Emperor's victory over the opponent's 100,000-strong army was not something magical at all, but that there was poison in the valley, and the poison should have permeated the valley.
It was in the air, so the enemy’s 100,000-strong army was unaware of it and was poisoned without even realizing it..."
"You mean, the air in that valley is poisonous."
Xi'er nodded, "Uncle Dan said that if you want to pass through the valley, you must cover your face with a thick cloth. In fact, it is just to prevent your mouth and nose from inhaling too much poisonous gas... If my guess is correct, if you inhale a small amount of that poison,
It should not lead to death, and if left for a long time, it will not produce more adverse symptoms on the human body... However, if you inhale too much, you will have hallucinations and even death."
