Chapter 510

In terms of chemical industry, calcium carbide is an important basic chemical raw material, which is mainly used to produce acetylene, organic synthesis, oxyacetylene welding, etc.

Calcium carbide is mainly composed of calcium carbide, the rest is free calcium oxide, carbon, silicon, magnesium, iron, aluminum compounds and a small amount of phosphide and sulfide. It is a kind of toxic substance and can not be in direct contact with human skin, otherwise it will itch and become red and swollen.

Xiao Li said, "is it used by the killer to heat the water?"

He frowned, "no, it's too dangerous to do that!"

"Dangerous? Doesn't it release heat? "

"It can really release heat, and it will not burn when it is dry. Once it meets water or moisture, it can quickly produce highly flammable acetylene gas. If it reaches a certain concentration in the air, it can also cause explosive disasters. How can the murderer know the harm and use it? What should he do if it explodes? This is contrary to his original intention of avoiding fire."

The killer must have used some clever way to heat the water, but it's not such a dangerous thing.

"I haven't finished yet..." Lin Mo interjected, "this is calcium carbide, but the assurance found a very strange thing in the test."

"Strange?"

Lin Mo nodded, "there is a little oily substance left in the stone, which is not found in ordinary calcium carbide. This oily substance will not mix with water, and it will volatilize when encountering phosphate powder, leaving no trace. If there is not a little oily substance left in the stone, they will not find it."

It's also thanks to Hu Hu. If she hadn't offered to test the stone, they always thought it was an ordinary stone and had nothing to do with the case.

"Stone? "Oil?"

It's time to screw up your eyebrows. There must be a connection between them.

When she went back to the hotel to have a rest, she also kept thinking about this problem. Her head was full of oil and stones, and she didn't even eat much dinner. Xiao Li cleverly packed one for her and asked her to take it back to the hotel, but she sat on the sofa and looked at the lunch box in a daze.

Ding, the mobile phone rings. This is the wechat message notification tone she set.

She opened the dialog box, Kangxi sent a picture of a meal, oil pan filled with vegetables and unknown meat.

Then the phone rang and she picked it up.

Kangxi asked with a smile: "do you see the delicious food?"

She was speechless. "You called just to let me see you eat?"

"No, didn't I mention to you last time that there was a hot spring hotel where I was filming?"

Of course, she remembered, and suddenly understood that he was starting to use delicious food to stimulate her to go on a visit.

There's nothing you can do without it.

"This dish is called rolling stone kidney flower. It's Liaoning cuisine. It looks very common, but what's interesting is that it's not the fire that heats the oil, but the scalded stone. Throw the scalded stone into the oil, and the oil will roll, and then scald all the ingredients with boiling oil. It's very delicious..."

He said a lot, but he only heard a few words - hot stone, boiling oil!

With a flash in her head, she jumped up from the sofa.

"I see!"

"What?" Kangxi asked at that end.

She smiles and kisses her cell phone, "Kangxi, I love you so much, really, I love you so much!"

Then she hung up.

At the other end, Kangxi was stunned at first, and then his face turned red slowly. He covered his face, and a burst of smoke came from his head

Geng Bu Mei was sitting opposite him. They were having dinner. It was a private room with a pavilion in the middle of a lake. It was elegant and tasteful. Looking at him, he not only blushed like a ripe tomato, but also grinned.

This is crazy!?

"What are you blushing for?" Isn't it to say a dish name to the empress? How can she blush?

Kangxi pointed to the mobile phone, giggling more vigorously, like eating a pot of Honey Bear like, "Hu Hu said she loved me!" He blushed, as if worried that Geng insomnia did not hear clearly, and repeated word by word, "yes, love, death, I, I have!"

His face was red and he turned around.

Geng Bumei casually replied, "every time I buy you Jia a luxury bag, she says the same thing!"

This is absolutely true. If a woman says that she loves you, it must be a man who has met her certain requirements, such as famous bags, jewelry, high-grade dresses, etc. He has calmed down.

Kangxi's face changed and he stretched out his feet and kicked him away.

With a puff, Geng Bumei was kicked into the river, and he didn't even have a chance to call for help.

In his heart, Xiao Chen lamented, "if you can't speak, don't say it. Look at the end, you need someone to jump down to save him.".

Kangxi continued to indulge in the beautiful words of love, unable to extricate himself.

Love, death, you and me

Love, death, you and me

In infinite loop
