After listening to Shao Yitian's story, Brother Bin nodded as if he didn't understand, and asked, "Xiao Shao, you mean that everyone's fingerprints are different, how do you know this?"

Shao Yitian said: "Brother Bing, this is no longer any secret on our earth, and the farmer uncle who farms at home knows it, so this is not a major knowledge at all. ”

When Brother Bin heard this, he looked suddenly enlightened, and said, "It seems that there is still a certain gap between the technology of the heavenly court and the mortal world. ”

At this time, Yang Jian also finished comparing the fingerprints of the two, and Yang Jian said: "Indeed, the fingerprints of me and Lu Zhenren are not the same!"

"Xiao Shao, now you go to the mortal world and find the way to extract fingerprints. Yang Jian said, because Yang Jian also wanted to solve the case quickly.

Although Yang Jian is a relative of the number one in the Heavenly Court, but after this file, there is also pressure, if he can't solve the case as soon as possible, he will definitely be gossiped outside!

As soon as Lu Dongbin heard what to extract the fingerprints on the teacup, he immediately came to his senses and asked, "What is the situation, tell me quickly." ”

Yang Jian explained to Lu Dongbin, and Lu Dongbin was surprised that there was such a way.

As soon as Yang Jian and Lu Dongbin heard that Tai Baixing was coming, they didn't dare to sit here and hold it up, so they immediately stood up and went out to greet them.

Shao Yitian knew that the reason why Tai Baixing came here must have been brought over by Li Qingyu.

Sure enough, when Shao Yitian followed Yang Jian and them outside, he saw Li Qingyu following behind Tai Baixing.

"Lord Taibai, please come in quickly!" Yang Jian immediately invited Tai Bai Xing into his office.

Tai Bai Xing didn't talk nonsense, and directly said his intentions: "I came here today to tell Director Yang that although this Xiao Shao is suspicious and can be investigated, he can't be bent into a trick." ”

Yang Jian hurriedly shook his head and said, "Lord Taibai, you can rest assured about this, even if you don't say it, with my relationship with Xiao Shao, I won't let him be hurt at all!"

"Yitian, are you okay?" Li Qingyu walked up to Shao Yitian's side and asked, for fear that Shao Yitian would be treated unfairly in the Public Security Bureau.

Shao Yitian smiled and said, "Do you think I look like someone who has something to do? Don't worry, I'm fine." ”

After Tai Baixing and Li Qingyu left, Shao Yitian immediately returned to the mortal world and found out the method of extracting the fingerprints on the teacup.

Shao Yitian checked it on the Internet, and it was probably divided into several categories, namely powder manifestation method, fumigation method, silver nitrate method, etc., Shao Yitian wrote down the above methods.

For the sake of insurance, Shao Yitian found Fu Shengming, the boss of the Dongshan District Public Security Bureau, and asked for his help. Fu Shengming agreed to Shao Yitian's request without any hesitation.

Fu Shengming immediately called a criminal policeman who specialized in this business, told Shao Yitian the method of fingerprinting on the teacup, and also demonstrated it himself.

After the demonstration, in order to deepen Shao Yitian's impression, he also asked Shao Yitian to do it himself.

Shao Yitian found that this fingerprint extraction is not a very complicated thing, what you have to do is to be patient, not to be in a hurry, take your time!

After learning such a skill, Shao Yitian thanked Fu Shengming and asked him for some silver powder to extract fingerprints.

Regarding Shao Yitian's request, Fu Shengming generously agreed. Because if it weren't for Shao Yitian's help, he would have lost his position as the number one player Fu Shengming would have lost a long time ago. So for Fu Shengming, Shao Yitian is his benefactor!

After learning the method of fingerprint extraction, Shao Yitian rushed to the heavenly court non-stop and went straight to the headquarters of the Public Security Bureau.

Seeing Shao Yitian coming, Binge was even more anxious than Yang Jian, and immediately stood up from the chair and asked happily, "Xiao Shao, have you found a way?"

Shao Yitian nodded and said, "I will naturally be able to catch it!"

Binge said: "Don't talk nonsense, let's go and extract the fingerprints on the teacup!"

So, the three of them came to Marshal Xuanbo's office, and after this incident, the people of the Public Security Bureau had already put Marshal Xuanbo's office on guard and did not let anyone approach.

The staff of Tianhe also have no intention of going to work at the moment, because such a thing has happened to their heads, and whoever still has the heart to go to work is talking about who the murderer is.

After arriving at Marshal Xuanbo's office, Marshal Xuanbo's body had been removed, but fortunately, nothing else in the office had been moved.

Shao Yitian found that there was no trace of a fight in Marshal Xuanbo's office at all, you must know that these immortals are all supernatural characters, and once there is a fight, it is the most normal thing for the house to be destroyed.

But now the scene of the crime is as if nothing had happened, which can only prove one problem, that is, the murderer must have taken advantage of Marshal Xuanbo to attack Marshal Xuanbo when he was defenseless.

And the only thing that can make Marshal Xuanbo defenseless can only be acquaintances, and the relationship should still be very familiar, otherwise Marshal Xuanbo can't be defenseless.

If Shao Yitian can find this, presumably the people in the Public Security Bureau will also think of it.

However, the priority now is not to investigate the situation at the scene, but to extract fingerprints.

Shao Yitian sprinkled the silver powder evenly on the teacup according to the method he learned, and after a while, human fingerprints appeared on the teacup. This is because people have sweat on their hands, and when the silver powder is sprinkled on it, there is a reaction, and the fingerprints can be clearly displayed.

Seeing this magical scene, Bing Ge and Yang Jian were stunned, although they had already learned from Shao Yitian's mouth that this method was feasible, but seeing it with their own eyes was another shock.

Of course, Shao Yitian was also very excited, after all, this was the first time he had achieved such success in his own operation.

Shao Yitian carefully collected the fingerprints on the teacup, of course, the fingerprints of the two teacups could not be let go, because no one knew which teacup was drunk by Marshal Xuanbo.

After the fingerprint collection was completed, Brother Bin walked to Shao Yitian's side and said with a smile: "Xiao Shao, this method sometimes tells me that I also want to learn." ”

Yang Jian immediately stepped forward and said, "Lu Zhenren, don't make trouble, you're not from the Public Security Bureau, why are you learning this?" Xiao Shao, this method of yours should tell me that if our Public Security Bureau has this method, the rate of solving cases will definitely increase in the future. ”

Shao Yitian saw that Yang Jian and Lu Dongbin were fighting over a toy like children, and hurriedly said with a smile: "This is very easy to learn, I'll teach you two when I have time!"

Hearing Shao Yitian's words, Yang Jian and Lu Dongbin nodded with a smile at the same time, saying that Shao Yitian was really interesting.
