Back to 90s she made a fortune from scientific research

Chapter 244 Very guilty, old guilty.

Qin Hongfei complained inwardly, and it was she who knocked out the heartbeat tester for sale.

The heartbeat tester is slightly different from the heart rate tester. The former is more inclined to use for lie detection. She doesn't know how the ordinary lie detector is, but she did it, and the detection rate is as high as [-]%.

In another world, the thing she made applied for a patent and was promoted to places with professional needs in various cities. She made a lot of money by relying on this. She didn’t know how much, but it was enough for her to invest in scientific research anyway. It consumes more than a year, and it is very profitable!

For the sake of money, she asked, "Will you buy it?"

"Multiple functions, you can test heart rate, test lies, and you can prepare one if there are elderly people at home with cardiovascular and cerebrovascular diseases! Multiple effects, only 880 eight, if you miss it, it will be gone." She tapped skillfully small ad.

81.218.11: "Why do I think you're a liar."

1.1.2.8: "Be confident and get rid of the feeling. When did the heart rate monitor become so convenient? It's still worth [-], [-] people are rushing to ask for it, especially the ones from major hospitals."

When Qin Hongfei saw it, she immediately reflected on herself, and humbly asked for advice, "Brother, may I ask, how much is the purchase price of this equipment in major hospitals?"

1.1.2.8 Seeing that she was asking me for advice, she was speechless, and replied, "This kind of large equipment must be priced at a price of [-] yuan. If it is better, it will be hundreds of thousands. I said you will not fake it." Be presentable, the price is false at first glance."

Qin Hongfei was educated, and replied to the host, "Sorry, I don't understand the market, change the price to 880, you deserve it!"

1.1.2.8:"……"

Have you ever seen a price that sits on the ground?

He has seen it.

Still crazy!

Just about to complain, that 81.218.11 actually replied and asked, "Fifty-eight thousand, can you really test whether my girlfriend likes me, in case you lie to me?"

Qin Hongfei said, "Then you can only admit defeat."

Listen, do you speak human words?

But very practical.

It is true that you can only admit it, otherwise what can you do.

Qin Hongfei said sincerely, "I can make it first, you come to see the goods, and then make a deal if it is suitable! How about it?"

81.218.11: "OK, how many days?"

Qin Hongfei said quickly, "I will reply to you within three days."

After the provisional agreement was made, Qin Hongfei didn't waste any more time, got off the net, went back to the repair shop to find some things she wanted and put them in the repair box. Then Ling went back to Lao Qin's house and closed the door. Go to school to eat, and retreat unshakably.

This made Third Aunt Qin couldn't help being curious, she asked her mother-in-law and said, "Mom, what is Hong Fei doing in the house all day, don't be silly."

Grandma Qin also found out that the child has been bored in the house for the past two days, but the farmland is busy. She hopes that each child can learn more from Qin Hongfei, so as to save worry and trouble, "Has she finished her homework yet?"

Third Aunt Qin replied, "It's finished."

Grandma Qin immediately went to work without looking back, "It's fine if you don't want to finish writing. After finishing writing, you love to play and love God, you care about them so much." The main reason is that it may not be useful if you want to manage them. Seeing it, he continued to work on his own affairs as he spoke.

Qin Hongfei is busy, Qin Concubine is bored, she can only read the script, read the script... I can't go to Hongfei, because she will stare at her with a look like, how can you waste time like this, very guilty, old guilty up.

It was really boring, and Qin Yun and the others dragged him out to play. It happened that the Bai family was nearby, and the children of the Li family were also playing. There were several hula hoops in their hands. The children of the Bai family looked at each other and wanted to borrow it to play. , but he was rejected on the grounds that he was afraid of playing badly. Just when he saw the Qin family's children coming out, he immediately forgot his disappointment and ran over to play with the Qin family's children.
