Chapter 72

Thank you to the book friends "Baolt", "MrSariel", and "Zhi Zun Bao" for their positive reviews.

……………………………………………………………………………

After Shen Donghai and the others left, the office became quiet again.

Jin Yunhao leaned back in his chair, sitting in front of the computer, watching the videos that Shen Donghai had brought back.

No lies, no lies, still no lies.

The dozen or so people that Shen Donghai and Yin Guohong investigated mostly held a positive attitude towards whether Jin Taicun had reformed, and none of them showed any signs of lying when they spoke.

"Snap."

Jin Yunhao broke another pen, but he didn't notice it himself.

It seems that Jin Taicun really has reformed.

Jin Yunhao reaffirmed this thought.

Although judging whether someone is lying by watching videos seems far-fetched, it actually has a scientific basis.

Dr. Paul Ekman, a 74-year-old American psychologist, primarily studies facial expression recognition, emotions, and interpersonal deception. In 1991, he received the Distinguished Scientific Contribution Award from the American Psychological Association for his research.

Dr. Ekman's research was named microexpression science, which mainly studies and summarizes how to determine whether someone is lying by observing their facial expressions and actions.

When Jin Yunhao was studying in the United States, he had the opportunity to learn microexpression science from Dr. Ekman and benefited greatly. He also gave lectures to FBI agents with Dr. Ekman and helped the FBI solve complex cases.

At the time, the American side had also invited him to join American citizenship and stay to work in the United States, but Jin Yunhao did not agree. He was eager to return to South Korea to become a Korean prosecutor.

Although he did not stay in the United States, Jin Yunhao has always maintained communication with Dr. Ekman, and his understanding of microexpression science has deepened over time.

Although Jin Yunhao does not have as deep an understanding of microexpression science as Dr. Ekman or his other senior classmates, he is fully capable of using it.

By observing on-site and watching videos afterward, he is very confident in his ability to determine whether someone is lying.

Through his observations at noon and watching the videos in the afternoon, Jin Yunhao found:

Although Jin Taicun is very intelligent and has strong self-control, his subconscious actions and expressions are beyond his control.

Jin Yunhao deliberately had Shen Donghai eat in front of Jin Taicun to show disrespect, to test his self-control and see if he could really control his emotions.

However, the results showed that Jin Taicun still subconsciously displayed feelings of disgust and dissatisfaction at the time.

Although Jin Taicun is intelligent and has a deep mind, he has not reached the level of a psychological master who can control most of his emotions and act for others to see.

Therefore, Jin Yunhao concluded that Jin Taicun really has reformed.

However, Jin Yunhao did not show this method to outsiders or explain it in detail to Shen Donghai.

The things he previously revealed to Shen Donghai were just the basics of microexpression science, and they are very similar to criminal psychology, leading Shen Donghai to mistakenly believe it was criminal psychology.

Apart from his mother and sister, Jin Yunhao has never trusted anyone, including Shen Donghai, who gradually became his friend. Never!

Therefore, outsiders, including Shen Donghai, do not know that Jin Yunhao has this investigative method.

South Korea is still in a state of ignorance regarding microexpression science. Although they know it is a new discipline, most people consider it a branch of criminal psychology and believe it has little practical use.

Therefore, no one values Jin Yunhao's experience or his ability in this area.

This situation aligns with Jin Yunhao's intentions, and he has kept his knowledge of microexpression science as his trump card.

"I hope that when I play this trump card, it will surprise you."

Jin Yunhao held a pen in his right hand, his thumb on the top of the pen. With a force, "snap," another pen was broken.

Jin Yunhao has already broken many pens by playing with them like lighters, but he didn't care.

After making his judgment, he quickly wrote a report and then left for home.

It was already 10 PM.

—

After returning to the apartment, Jin Yunhao stopped at the door.

A beam of light shone through the door crack.

Is there a thief?

What a joke, although this apartment is not the highest level, it is not something just anyone can afford. The security is very tight, and there is no way a thief could get in.

Then who could it be?

There are only two sets of keys for this apartment: one for Jin Yunhao and one for Zheng Daqin.

Is it Mom?

"Snap."

Jin Yunhao stood at the door and carefully pushed it open. Indeed, it was Zheng Daqin.

At that moment, Zheng Daqin was kneeling on the ground, wiping the floor with a cloth.

"Mom, why are you here?" Jin Yunhao took off his shoes and quickly walked into the room, helping Zheng Daqin up and asking with concern.

"Oh, our Yunhao is off work. Hehe, Prosecutor Jin, you've worked hard." Zheng Daqin looked at Jin Yunhao with a smile, playfully teasing him.

"Mom, who taught you to tease your son like that?" Jin Yunhao said, taking the cloth from Zheng Daqin:

"Don't clean anymore. The floor is cold, and it's not good to kneel on it for a long time. Put it here, and I'll clean it later."

"Ah, you big man, why should you clean? Of course, it's the woman's job." Zheng Daqin tried to take the cloth back but failed, and then complained:

"I'm not saying this to criticize you, but you're almost 26 years old. You should consider your marriage. If you live alone, I won't be at ease. Look, just take the housework, if I don't come, no one will help you."

Jin Yunhao shook his head and smiled bitterly. Even old people love to pressure their children into marriage: "Mom, I'm just busy with work. I just started my job and received a new task. How can I have time to date?"

Hearing Jin Yunhao's explanation, Zheng Daqin thought for a moment and agreed: "Ah, that's true. Just starting work, you should work hard. Besides, a prosecutor's work is busy, and I understand. How about I help you find someone and arrange a blind date?"

Seeing that Zheng Daqin was not giving up, Jin Yunhao felt his head was bigger than two heads: "Mom... just rest assured. After this new period, I will definitely find a daughter-in-law for you."

There was no other way; Jin Yunhao had to use the delaying tactic.

"Good... you said it yourself." Zheng Daqin's eyes narrowed with joy.

She really wanted to see what kind of daughter-in-law her excellent son would find.
