From a distance, Qin Hongfei glanced casually with her eyes, and reminded Qin Yun without turning her head, "Reagent, that in your hand is mosquito blood, used to research and make something to repel mosquitoes. Don't touch it, some things there are poisonous. I extracted it from poisonous flowers and plants. Be careful not to poison yourself. I haven't even researched the antidote yet." There are fields nearby, and when the weather gets hot, there are many unavoidable mosquitoes. There is no mosquito coil liquid in this era, and the smell of mosquito coils is too strong, which she doesn't like.
Qin Yun, who had already opened the lid and curiously put a little red liquid from the bottle on his index finger, turned green! "Ahhh! Why didn't you say so earlier!"
Oh my god!
Such a small bottle is full of mosquito blood?
You have to kill several mosquitoes to extract it!
This little half tube.
Also, will I be poisoned if I touch it?
Qin Hongfei found the 'toy' and called Qin Fei to help. She looked back at him speechlessly, her bright face expressionless: "I didn't blame you for messing with my things, but you blame me?"
Qin Yun thought so too and said timidly, "I'm sorry."
Qin Hongfei said, "I forgive you. It's not very poisonous. At most it may cause itching or swelling. You don't have to be afraid since you have thick skin. But don't touch it carelessly next time." These are all relatively small things.

She sometimes catches venomous snakes and other things for research.
Some people only study a certain area, but Qin Hongfei knows many teachers. She has read a little bit of this and a little bit of that since she was a child. She is very interested in the ocean of knowledge and knows a little bit of everything. She is not greedy and does not seek to be a master of everything. She just needs to use it to cope with the common sense needs of daily life.
Qin Yun stared at his index finger and suddenly said, "This... it would be good if it was swollen. It would give me a reason not to do my homework, right?"
Qin Hongfei didn't want to pay attention to him anymore, and she and Qin Fei worked together to move the small things to the vacated space on the table. They were all a pile of loose things. However, even such a pile of loose things was quickly assembled into a finished product by Qin Hongfei.
First, there is a lightweight electronic instrument scanning device.
Then there was a screen with messy wires. Qin Hongfei connected all the wires and a simple picture immediately popped up.
The heartbeat monitor is an improved version of the heart rate monitor developed by Qin Hongfei, but it is also quite different because it has a multi-functional mode and is also portable and light enough to carry around.
Spare parts were also hard to find, so Qin Hongfei scraped together some and went to second-hand markets many times. In the end, she got a few parts herself before she could make it. She spent a lot of money, and her 50,000 savings was almost half gone, but fortunately she succeeded.
"Why did you call me over here?" The chief walked in with a cold face.
"Testing the next new toy." Qin Hongfei's tone was surprisingly kind, "Is Tang Xiaojin busy? If not, call him over as well."
well!
It’s hard to find mice these days, and we have to take care of their lives.
If it were in the previous life, whenever she needed it, someone would send her a 'guinea pig' for experiments and she could toy with it as she pleased, without having to worry about anything else.
When the chief heard her say test, he said speechlessly but firmly: "Don't even think about it."
What are you thinking of using Tang Xiaojin as a guinea pig? Believe it or not, Canglao could scold you to death if he knew!
Back in the 1990s, she became rich through scientific research
