Back to 90s she made a fortune from scientific research

Chapter 283 The old man knows that he can be scolded to death, don't you believe it!

From a distance, Qin Hongfei glanced at it casually from the corner of her eye, and reminded Qin Yun without turning her head, "Reagent, the one in your hand is mosquito blood, used to research and make something against mosquitoes. You Don't touch it, some things there are poisonous, I extracted them from poisonous flowers and plants, be careful to poison yourself, I haven't researched the antidote yet." There are fields all around here, and it's unavoidable when the weather is hot. There are a lot of mosquitoes, and there is no mosquito repellent liquid in this era, and the smell of mosquito repellent incense is too strong, she doesn't like it.

Qin Yun's face turned green after he opened the cap, and curiously dipped a little red on his index finger from the bottle! "Ahhh! Why didn't you say it earlier!"

I go!

Such a small bottle is full of mosquito blood?

You can only extract it by killing a few mosquitoes!

This is a small half pipe.

Also, will I be poisoned if I touch it?

Qin Hongfei found out the 'toy' and called Concubine Qin to help her. She looked back at him speechlessly, her bright little face was expressionless: "I don't blame you for messing with my things, you blame me coming?"

Qin Yun thought about it, and said cowardly, "I'm sorry."

Qin Hongfei said, "Forgive you, it's not very poisonous, at most it may itch or swell up, don't be afraid of your rough skin, but don't touch it next time." These are relatively small stuff.

She sometimes catches poisonous snakes or something for research.

Some people do research in a fixed area, but Qin Hongfei knows many teachers. She has been interested in the ocean world of learning since she was a child.She is not greedy, does not pursue learning, but is just enough to meet the daily knowledge needs of life.

Qin Yun stared at his index finger, and suddenly said, "It... it would be fine if it was swollen, so there is a reason for not doing homework, isn't it?"

Qin Hongfei didn't want to talk to him anymore, and worked together with Concubine Qin to move the small things to the empty space on the table. They were all piles of loose things, but it was this pile of loose things that was in Qin Hongfei's hands. After several assembly, the finished product is quickly formed.

The first is a lightweight electronic instrument scanning device.

Then there was a screen with messy lines, Qin Hongfei connected all the lines, and immediately jumped out of a simple picture.

The heart rate monitor is an improved version of Qin Hongfei's extension from the heart rate monitor, but it is different because it incorporates a multi-function mode, but at the same time it is made into a portable model, which is light and portable.

Parts were also hard to find. Qin Hongfei made a lot of trips to the second-hand market, and finally made a few parts by herself. It cost a lot of money, and the deposit of [-] yuan was reduced by almost one-half. But luckily it worked.

"What did you call me over here?" The first one walked in with a cold face.

"Test the next new toy." Qin Hongfei's tone was surprisingly kind, "Is Tang Xiaojin busy? Call him over if you're not busy."

Ugh!

It's hard to find little white mice these days, and you have to take care of their lives.

If it was in the last life, as long as she needed, someone could send her a 'white mouse' for experimentation at any time, toss it to her heart's content, don't worry about it.

When she first heard her talking about the test, she replied speechlessly but firmly: "Don't think about it."

Take Tang Xiaojin as a guinea pig, what are you thinking, the old man knows that he can scold you to death, believe it or not!
