Chapter 286 Single dog.

Qin Hongfei originally thought that the machine was not made successfully, but it turned out that Qin Yun was lying. She was speechless for a moment.

Qin Yun was also embarrassed in the face of everyone's gaze, and he forced himself to explain, "I just tested it for you to see if it works well." Yes, that's it, "But it works well, but it's not stable."

Qin Hongfei also had concerns in this regard, so she naturally focused her attention on Xiaobai, oh, no, Tang Jinnan and Shou.

Shou said speechlessly, "Don't joke."

How could they try such an unknown thing with their identities? However, before he finished speaking, he saw his friend had already walked up. He swallowed his words and frowned, showing his disapproval.

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

Qin Hongfei put the bracelet on him, so fast that it seemed as if she was afraid that he would regret it the next second.

After everything was ready,

Qin Yun and Qin Fei quickly gathered around and asked casually, "Name, answer the truth."

"Tang Jinnan."

"Age, answer a lie."

"Thirty."

The data value jumped when answering the truth and lies.

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

Tang Jinnan's eyes suddenly turned to her.

Beside him, Shou suddenly frowned.

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

Qin Yun and Qin Fei immediately looked over with gossipy eyes.

Tang Jinnan originally suspected that Qin Hongfei was gossiping for personal gain, but seeing her expression, he knew that he had guessed too much, she was just testing, put away the thought, and he also calmed down, "No."

Shou walked around to the machine, the value was within the normal range, indicating that Tang Xiaojin was not lying.

He looked at Qin Hongfei, then at his friend, and remained silent.

Qin Hongfei didn't notice Shou's little move, and even if she did, she wouldn't care. After seeing that the value was flat, she sighed, "Single dog."

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

The following tests went smoothly.

Shou also tested it, and the three people proved that the machine was reliable.

Qin Hongfei was very satisfied, and her money was not wasted. She looked at Tang Jinnan with clear eyes and said, "Give me your opinion from your professional perspective. If this machine is to be sold, how about it?"

Tang Jinnan's cold eyes showed a look of as expected.

Shou said puzzledly, "What do you mean?"

Tang Jinnan buttoned up his sleeves politely, "Do you think she is testing the function for you to see?"

Didn't Shou swallow his words back under the gaze of the two? He always felt that he would be treated as a fool if he said it out loud.

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

Reading the error-free version! 6=9+Shu_bar first published this novel.

He was stunned for a moment, and quickly answered without thinking, "Hot!"

There are many men, women and children with heart problems in the world! However, such tests often require going to the hospital and having professional equipment to do the test, which is very troublesome.

But if such a device appears on the market in Yangcheng City! For those patients with such diseases at home, it is a great blessing.

Let's not talk about ordinary people! But those who have some money will rush to buy it and are willing to buy it.

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

The function of this thing is not just as simple as being used for family use!

If some special professions need to go out, they can also carry one, and then use it on the spot and conduct tests.
