Li Jin was stunned, why were his eyes so bright, as if the stars were hidden in his eyes, she glanced over and didn't want to look at it anymore.

"That's how you found out? Chen Rufan's is reasonable, but Qin Xiaoyu's is too unrealistic. Li Jin said.

"Don't question me." He snorted lightly, "You haven't finished yet, what are you anxious about?" ”

"You're too slow, and you've been off topic." Li Jin blurted out.

Gu Qingyu, "......"

"In the end, it was determined that the two of them were murderers, and in terms of behavioral analysis, it was because of an inconspicuous sentence, Chen Rufan said, the smell of blood in this room is so big."

Completely unnoticed this sentence.

"Then, Qin Xiaoyu said that she went to Chen Wanyi's room at half past eleven and didn't smell blood, and he was reminding Qin Xiaoyu."

"It turns out she's lying." Li Jin sighed.

"Oh, at half past eleven, she is probably happily slashing with a knife." Gu Qingyu said lightly.

Li Jin......

Can you not say that it is so breezy and bland?

"I'm good at solving cases from mental profiling and behavioral analysis, if from a criminal point of view, this case has more loopholes, fingerprints, footprints, bloodstains, etc., this case will be solved soon, so my vacation was ruined by this immature murder, and I really feel very unhappy."

Li Jin suddenly laughed, he was really naïve. "If we hadn't called the police, we would have been in danger tonight."

"If I don't call the police, I can find out the murderer immediately, bring him to justice, and tie him up, you see how he continues to kill."

"......" Li Jin smiled, knowing that what he said was a joke, she asked, "You always knew how the electric switch was broken, right?"

Gu Qingyu raised his eyebrows, "No, I realized it because you said the introduction." ”

Li Jin was dumbfounded, "I thought you knew all along." ”

"So you know the process of the installation, why don't you tell it?"

Li Jin said: "It's just a guess, wrapping black powder in cotton, layering on top of each other, and stacking a large number of them makes the air permeability inside poor, and the heat increases the temperature, plus the flammable gas produced by microbial decomposition, so it is easy to catch fire, it should be like this, even if the person is not there, it can burn, she is really smart."

"You're good at chemistry, and thank you for your cooperation today." Gu Qingyu looked at her and said.

"So, Miss Li Jin, you seem to be in a better mood now, can you follow me back to the provincial hall to make a record?"

Li Jin's smile suddenly froze, and he asked a little coldly: "You told me so much just so that I could go back with you to make a record?"

"Do you think I have that time in outer space?" Gu Qingyu stared at her lightly, "Whether you want to go or not, you have to make a record, but that's their business, I'm not responsible, I'm urging you because, you promised Jiang Beiyan to have dinner with us in the evening, and the time is running out, so Miss Li Jin, who is having a temper, can you hurry up." ”

Li Jin turned her face away and said lightly, "I didn't lose my temper. ”

Gu Qingyu stared at her with heavy black eyes, and sighed lightly, "I have never seen a woman more troublesome than you." ”

“……”

"Captain Gu, it's time to go back to the provincial hall, it's all packed up." A young man in a police uniform walked over and said respectfully to Gu Qingyu.

The police turned their heads again. "Miss Li, please go back to the police station with us to make a record."

Li Jin nodded indifferently.
