"What the hell is this?" Shou frowned and asked, reached out and touched the gun, and then looked at the device, and suddenly something popped into his mind, "A device that tests heart rate?" Heart rate monitor. ”

"No, it's a heartbeat detector, which of you comes first." Qin Hongshou had already assembled the parts, and after plugging in the power supply, the yellow gun with a bit of weight suddenly lit up, and she held the gun and looked around the three of them.

Don't say the first two words, retreat first to respect.

Lao Tzu won't be your experiment!

Qin Yun was a little puzzled, "This is the toy you are talking about?" "He couldn't read what a toy it was."

The first look is weird, toy fart!

Who used the monitor as a toy, glanced at Qin Hongshuang, he shut up! There are really people, and there is one in front of them.

Qin Hongshou said calmly, "It's a toy, I'll show you, stretch out your hand......" She has always been very kind and talkative about the experiment, and after putting on the bracelet for Qin Yun herself, she pressed the switch!

Qin Yun's heart trembled, but he only heard a dripping sound, he was not dead! Fortunately, he looked curiously at the device that the three pairs of eyes were staring at, scratching his heart and lungs, "What." ”

Concubine Qin was also a little magical, "Scarlet, this is the one when I was looking for my cousin last time?" "It's all curves, and there's values.

"That's a life monitor, it's not quite the same, but the principle is similar, these values are the normal values of the body, the human body's heartbeat is 60 to 100 beats, the pulse is the same, this is the blood pressure 90mmHg to 140 value is systolic blood pressure, and the other value is diastolic blood pressure and ......"

As she spoke, she suddenly noticed that except for the first, the other two were all confused, what are you talking about, you understand every word, and you don't understand it when you put it together.

Qin Hongshou felt that she had said a bunch of nonsense, "In short, the current value is the value of the human body in a very good state. But this thing functions more than that, Brother Qin Yun, let me ask you a few questions, and you answer me in a panic. ”

Qin Yun was dumbfounded, "Are you in a panic?" ”

Qin Hongfei nodded, "Let's tell the truth first to make the answer, what did you eat in the morning." ”

Qin Yun replied; "Porridge."

"Have you been punished by the teacher at school during the day?"

"No, the teacher still praised me for my progress."

"The name of the person you like."

"......" Qin Yun hesitated, "Bai Duo." ”

Qin Hongshou and Concubine Qin looked at him with gossip, such a pure name, it is estimated that he is a little cutie, and he always feels that you are not worthy.

Qin Yun's face darkened, "What kind of eyes do you have." ”

Qin Hongshou shook his head, continued to ask a few questions, then wrote it down in his notebook, let it go, and said, "Now I will ask you these questions repeatedly, and you answer in a panic." ”

"What did you have for breakfast?"

"McDonald's!"

Concubine Qin found that the value on the device jumped, and suddenly sighed, "How has it changed?" ”

The first was about to leave, but when he heard the sound, he paused and looked around, and when he saw it, his expression suddenly condensed slightly.

As Qin Hongshou asked a question, Qin Yun answered in a panic, the more outrageous, the more the value deviated from the normal range, which indirectly proved that this kid was panicking.

What a heartbeat tester, a lie detector is about the same.

After asking the panic, the fluctuation of the value was recorded.

Qin Hongfei was quite satisfied, "Next ask normal, who is the person you like?" ”

Qin Yun said without hesitation, "Bai Duo." He remembered the girl down the hallway who handed him the book, and he felt his heart beat faster.

The instrument suddenly emitted a long beep like a honeycomb.
