On the third floor, in the bedroom, Chu He found the water cup on the bedside table.

This is an ordinary glass with a circle at the top and a glass at the bottom, and the water in the cup is the same as ordinary drinking water in terms of color and smell.

Out of nowhere, he found a pair of polypropylene gloves to put on his hand, and then carefully picked up the water glass.

"It's completely dissolved in water. ”

Chu He sniffed lightly and noticed something strange.

"Go get me a glass with a thinner wall. Chu He said to Yang Xiong.

"Good. Yang Xiong nodded.

Yang Xiong left for a while, and then came back with an ordinary glass of water in his hand.

Chu He poured a third of the poison into it, then picked up a lighter and began to burn it.

"Boss, what ...... are you 'high temperature disinfection'??" Li Xingguang wondered.

This disinfection is not the other disinfection.

"It's not. ”

Chu He shook his head: "High temperature can kill bacteria and destroy snake venom, but there is no way to deal with this kind of thing." ”

"Do you know what kind of poison this is?" asked Li Xingguang.

Chu He put the mouth of the cup under his nose and sniffed it, and was even more convinced: "It's not smart, it's arsenic." ”

One of the oldest poisons.

The crane top red often mentioned in TV dramas is actually unprocessed arsenic, called red letter stone.

Chu He handed them the cup: "Arsenic will exude a special question at high temperatures, Lao Yang, a northern man like you should be familiar with it." ”

Yang Xiong took it, smelled it, and a flash of inspiration flashed in his mind: "It's garlic?"

He handed the cup to the others.

"Yes. ”

Chu He nodded: "Arsenic trioxide, that is, arsenic can smell garlic after heating, with a lethal dose of 60-200mg, this glass of water is enough for me to die seven or eight times." ”

"I hate you so much. Li Xingguang was amazed.

"Anyway, I like garlic a lot, why do I feel disgusted when I smell it?" Yang Xiong was a little puzzled.

"Because the gas that heats this thing is also poisonous. Chu He tilted his head.

"Damn. ”

"it. ”

". ”

The six of them picked their throats and blew their breath, eager to squeeze all the air out of their lungs.

Poison is no joke, especially arsenic, which is highly toxic.

"Don't worry, my heating temperature is not high, and you don't suck much, it's not harmful to the human body, at most it's a little disgusting. Chu He waved his hand absently.

"That's good, that's good. The six were stunned.

"Talking about toxicity aside from the dose is called hooliganism. Chu He shook his head.

"These two cups and the water in them can't be wanted, find a suitable identification agency, check the toxicity again, and confirm it. Chu He asked Li Xingguang, who was holding the cup.

"Understood. Li Xingguang nodded.

"Go check all the water and food in the villa. Chu He said to Yang Xiong.

"Understood. Yang Xiong nodded.

There were no clues in the bedroom, and the maid was cautious, not to mention fingerprints, not even footprints.

"Shall we close the villa?" Huang Zhiyang said.

"No, it will startle the snake. ”

Chu He shook his head: "If they can come in once, they can come in a second time." ”

If the maid could come in again, Chu He would be sure to catch the turtle in the urn.

"They?!"

Everyone looked at each other: "Do you know who did it?"

"I guessed a little in my heart, but I couldn't figure out my real identity. Chu He sighed.

The roof leak happened to rain overnight.

The mountain rain is coming, and the wind is full of buildings.
