This made everyone's eyes fall on the machine. Tang Jinnan found that the door was open and many people gathered here, so he also walked over. As soon as he came in, he heard the machine calling.

He paused and understood at a glance, "Polygraph?"

Qin Hongfei looked at him deeply. It was not surprising that he understood it. If a medical student could not understand it, then he would be a waste. Tang Jinnan was obviously not on the waste list.

But she corrected him, "Heart rate tester."

Tang Jinnan's beautiful eyebrows were frivolous, "What's the difference?"

In essence, the principle is the same thing.

Qin Hongfei did not say anything. There is still a difference, the function is different.

The long sound of the equipment continued, but after Qin Yun's heartbeat turned into shock, it slowly stabilized.

Qin Yun was shocked, "Is it broken?"

Qin Hongfei explained, "It's not broken, your adrenaline is soaring, causing your heartbeat to increase, beyond the normal range, so the machine is issuing a warning. It's normal, you are not going to die, don't worry."

Qin Yun: "..."

What do you mean I'm going to die, can't you talk properly?

Qin Hongfei asked directly, "You like that Bai Duo very much."

Several pairs of eyes looked at her at the same time. Even Qin Yun, who was thick-skinned, couldn't stand it. He said depressedly, "Of course, you thought I was joking with you last time. Do I look like that kind of person?"

Qin Hongfei held her cheek, her bright face expressionless, and said in a positive tone, "You haven't confessed yet."

Qin Yun shook his head, "Well, I wanted to confess last time, but a teacher passed by, and I didn't tell her because I was afraid that she would be punished. How did you know? It was also presented by a machine?" Is it so awesome?

Qin Hongfei said, "I guess so."

She said silently in her heart, if you confess, you will die in the light, can adrenaline soar so high? It's too late to be sad.

Don't ask her why she is so sure that Qin Yun will fail in his confession. From the big data, the probability of first love dying in the light is as high as 90% of the total data. In other words, out of ten couples, at least nine pairs of first love will basically break up. Even if there is one pair left, if the scope is expanded, out of a hundred pairs of first love, not necessarily two pairs can make it to the end.

The reason is that most people's first love happens in school, which is when people's minds, personalities, and world outlook are formed. It is only when they enter the society that their personalities are truly stable. Before that, it is adolescence. Adolescent feelings usually come and go quickly. Only one in a thousand can complete the long-distance race on campus!

But she didn't plan to tell Qin Yun this.

How can people who don't die in the light be considered to have had youth.

"Will it always call like this?" Qin Fei asked curiously.

"No, it will be fine once the heartbeat calms down." Qin Hongfei answered. Sure enough, after a while, the machine slowly calmed down. The main reason was that with so many people watching the excitement, Qin Yun couldn't think about his white moonlight.

Qin Hongfei continued to ask questions, which were basically in line with the rules. When it came to the last question, Qin Hongfei asked, "Have you been punished by the teacher at school during the day?" Qin

Yun answered calmly and quickly, "No, I was even praised by the teacher for my progress."

Qin Hongfei saw that the data jumped suddenly and looked puzzled.

Something went wrong?

However, she soon realized that something was wrong and looked at Qin Yun. This guy lied!

Qin Fei now understood how the machine worked, and said directly, "Qin Yun, you are lying, why are the values ​​suddenly wrong?"

Qin Yun felt guilty.

Qin Fei shouted, "Ah, the values ​​have changed again! But Qin Yun answered the truth." She was confused.

Qin Hongfei also frowned, huh? Something went wrong?

Didn't work? I

was just thinking about it.
