Chapter 244 I feel guilty. I always feel guilty.

Qin Hongfei complained internally, she was the one who revealed that the heartbeat tester was for sale.

The heartbeat tester is slightly different from the heart rate test. The former is more suitable for lie detection. She doesn't know how an ordinary lie detector is, but the one she uses has a detection probability of 90% accuracy.

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

For money's sake, she asked, "Do you want to buy it?"

"It has many functions. It can test heart rate and lies. If you have elderly people at home with cardiovascular and cerebrovascular diseases, you can also prepare one! It has multiple effects. It only costs 18,888. If you miss it, it's gone." She said skillfully knocking out small ads.

81.218.11: "Why do I think you are a liar?"

1.1.2.8: "Be confident and get rid of your feelings. When did heart rate testers become so convenient? People are rushing to get them, especially from major hospitals."

When Qin Hongfei saw it, she immediately reflected on herself and humbly asked for advice, "Brother, how much does this equipment cost in major hospitals?"

1.1.2.8 Seeing that she was asking for advice, he was speechless and replied, "You must pay a minimum price of 100,000 yuan for this kind of large-scale equipment. The better price is hundreds of thousands. Even if I tell you to fake it, you won't fake it." It’s decent, but the price is worth it. ”

Qin Hongfei learned the lesson and replied to the poster, "Sorry, I don't understand the market. Please change the price. Fifty-eight thousand, eight hundred and eighty-eight, you deserve it!"

1.1.2.8: "..."

Have you ever seen people raising prices from the ground up?

Grandma Qin also discovered that the child had been bored in the house for the past two days, but the farmland was busy. She wished that every child could learn more from Qin Hongfei, so as to save worry and trouble. "Has she finished her homework?"

Aunt Qin replied, "Let's finish writing."

Grandma Qin immediately worked without looking back and said, "It's okay if you finish writing. Once you finish writing, love to play and fall in love with God, you can control them so much."
