Back to 90s she made a fortune from scientific research

Chapter 286 Single dog.

Qin Hongfei thought it was because the machine failed, but it turned out that Qin Yun had lied, and she was speechless for a while.

Facing the gazes of everyone, Qin Yun was also embarrassed, and forced himself to explain, "I just tested it for you to see if it works." That's right, that's it, "But it's quite easy to use, just Steady or not?"

Qin Hongfei was also worried, so she naturally focused on Xiaobai, oh no, Tang Jinnan and Shou.

Said speechlessly, "Stop joking."

How could it be possible for the two of them to try something of unknown origin, but before they finished speaking, they saw their friend walking up, and he immediately swallowed the words, frowning to show disapproval.

Tang Jinnan silently stretched out his fair and slender hand towards Qin Hongfei.

Qin Hongfei put on the bracelet for him, as quickly as if she was afraid that he would regret it in the next second.

When ready.

Concubine Qin Yun and Concubine Qin quickly came up to watch, and she casually asked, "Name, answer the truth."

"Tang Jinnan."

"Age, the answer is false."

"thirty."

The data values ​​jumped in both true and false answers.

Qin Hongfei asked another question, she asked, "What's the name of the person you like, answer the truth."

Tang Jinnan's eyes turned to her abruptly.

On the side, the head suddenly frowned.

Qin Hongfei didn't know why, so she subconsciously touched her face, thinking that something was on it, "Why are you looking at me like that? Answer the question!"

Qin Yun and Qin Fei's gossiping eyes immediately cast their gazes over.

Tang Jinnan originally suspected that Qin Hongfei was gossiping about sham public affairs for personal gain, but by looking at her expression, he knew that he guessed too much. She was just testing. Putting his thoughts away, he also calmed down, "No."

After taking the first step to the machine, the value is within the normal range, which shows that Tang Xiaojin is not lying.

He looked at Qin Hongfei, and then at his friend's, but he remained silent.

Qin Hongfei didn't notice the first little trick, and even if she found out, she wouldn't care about it. After seeing the value without fluctuations, she sighed, "Single dog."

Tang Jinnan didn't understand what a single dog meant, but he could tell from Qin Hongfei's expression that it wasn't a good word, so he decided not to ask.

Subsequent tests also went well.

The first also tested it again, and the three people tried it, and they all proved that the machine is very reliable.

Qin Hongfei was very satisfied. Her money was not wasted. She looked at Tang Jinnan with clear eyes and said, "Let me give you an opinion from your professional point of view. If this machine is going to sell, how about it?"

A sure look appeared in Tang Jinnan's cold eyes.

Puzzled, the first asked, "What do you mean?"

Tang Jin Nansiwen buttoned up his sleeves, "Do you think she is showing you the test function?"

Didn't the first sentence be swallowed under the eyes of the two of them, what the hell always felt that if they said it, they would be regarded as fools.

Tang Jinnan looked at the device and said calmly, "Heart rate monitoring has always been a medical device, and it is only suitable for hospitals and research. When it can be transformed into a portable household item, what do you think?"

I was taken aback for a moment, and quickly replied without thinking, "Most popular!"

There are many men, women and children with heart problems all over the world!However, testing in this area often requires going to a hospital, and it is very troublesome to have professional equipment for testing.

But if there is such a device on the surface of the central city!That is a great blessing for those patients with this disease in their families.

Let alone ordinary people!But anyone with a little money will grab it crazy and be willing to buy it.

After all, the cost of treatment in this area is not low, not low.

The function of this thing is not just for family use!

When some special occupations go out, if necessary, one can also be carried, and then used and tested on site.
