He locked onto Elvis with his first foot, but was counterattacked by the opponent with his second foot.

It’s not that I’m too weak, but the strength hidden behind the other party is too terrifying.

An hour later, Zeng Qi, who was far away in China, received a call from Kate.

Considering that there was a bug in the house, Kate hid in the basement to make the call.

Zeng Qi asked anxiously, "Kate, is there any news about my father?"

Kate: "I'm sorry, I can't help you trace it any further."

Zeng Qi said in a deep voice: "Why?"

Kate: "There was a terrible power around Elvis. I received a warning from them. They threatened my son and my mother and also planted a bug in my house."

On the other end of the phone, Zeng Qi's brows were getting tighter and tighter.

He said slowly, "Kath, tell me all the speculations you know. I don't need the deposit, and you don't have to investigate further."

After Zeng Qi finished speaking, Kate on the other end of the phone was obviously stunned for a moment.

After a while, Kate began to reason, "I guess Elvis knew about your father's disappearance."

Zeng Qi was puzzled: "Tell me your guess."

Kate: "The cloned car your father disappeared in disappeared silently. There must be a very powerful force behind it. It is very likely the force that threatened me today."

His eyes lit up, and Zeng Qi agreed with Kate's inference. This was the keen sense of a professional policeman.

Zeng Qi: "Kate, it's been a week and I haven't received any ransom calls. I'm curious why they arrested my father."

Kate: "Recall carefully whether your father has any connection with this group of people, and whether your father has what they need."

His eyes lit up again, and Zeng Qi knew what he should do. Kate had enlightened him.

"Thank you, Kate. If nothing unexpected happens, we will meet soon." Zeng Qi said and hung up the phone.

His last sentence surprised Kate on the other end of the phone. What did this young man mean by his last sentence?

Could it be that he still refuses to give up and doesn't believe me? Kate was a little confused.

…

Zeng Mishan's laboratory requires a password to open.

Zeng Qi opened the door with just a few clicks, even though his wife didn't know the password.

Zeng Qi entered the laboratory, turned on Zeng Mishan's computer, and began to read all of his father's recent research.

Soon he was stunned by a video.

The video replays an outdoor scene. Zeng Mishan is holding a slingshot in his hand, and the ammunition is a white crystal that looks like rock candy.

Lao Zeng put the rock sugar into the leather bag of the slingshot and began to aim at the experimental dummy twenty meters away.

With a snap, the slingshot shot out the rock candy, and with a deafening explosion, the dummy was blown into pieces.

In the video, Zeng Mishan cheered and began to explain himself: This is the fifteenth experiment on the new type of mercury fulminate. When the impact force is greater than 1 MPa, it will trigger an explosion.

"Oh my god... Lao Zeng, Lao Zeng, after thirty years of research, you finally figured out mercury fulminate."

His eyes were full of admiration. Anyone who knows chemistry knows the dangers of mercury fulminate. Zeng Qi knew it very well. If it were him, he would never be able to reach Lao Zeng's level.

Zeng Qi recalled the production process of mercury fulminate.

Mercury nitrate is produced by the reaction of mercury and nitric acid.

Mercury nitrate can then react with ethanol to produce gray fulminate of mercury.

If a small amount of hydrochloric acid and copper is added to the reaction, the fulminate of mercury produced is white fulminate of mercury.

Mercury fulminate prepared by the old method is highly sensitive to flame, needle prick and impact.

If you are not careful, you can get yourself into heaven.

"I need to know how Lao Zeng stabilized mercury fulminate."

Zeng Qi continued to watch the video, as if he was possessed.

Little did he know that a door to a new world was slowly opening towards him.

"Old Zeng is no ordinary man. To make mercury fulminate even more unstable, he even tried adding silver fulminate."

This continued for a whole day, and Zeng Qi even found a note left by Zeng Mishan.

The operability of each step is described in detail above.

At this moment, Zeng Qi was like watching a host teaching a game.

In order to verify the technology, Zeng Qi put on Zeng Mishan's work clothes and started the experiment for some unknown reason.

He began to work step by step according to the notebook.

In the first step, he poured the weighed ethanol into the flask, placed the flask in a plastic basin, and filled the basin with an appropriate amount of warm water.

The second step is to put the weighed nitric acid into a small triangular flask, directly add the weighed mercury, and shake it by hand.

It takes 30 minutes for the mercury to dissolve. No heating is allowed during the process to ensure that the mercury is completely dissolved.

Because mercury ions are highly toxic, you need to pay attention to safety.

The third step is to quickly pour the nitric acid solution into the ethanol prepared in the first step. No other operations are required. Stand far away, observe the reaction phenomenon, and record the reaction time.

The fourth step is to prepare a synthetic solution. This solution was created by Lao Zeng after 30 years of hard work. It can stabilize mercury fulminate very well.

This step is the most difficult. There are dozens of synthetic materials alone, and it also requires the use of several expensive equipment to operate simultaneously.

It was no less than a thrilling operation...
