Zhang Guo was helpless.

Recently, his career seems to have ushered in a long-awaited period of growth, not in terms of income, but in terms of the quality of cases.

Unlike those Europa countries, the vast majority of cases in China are solved by the public security and national security departments, and private investigators in some countries can participate in the investigation of major cases, become long-term advisers to the police, and even have access to the police station.

In China, the main business undertaken by private detectives is to catch rapists and find people, and occasionally find cats, dogs, and laisseiners.

To do this work, as long as the brain is bright and willing to make friends, it is not difficult to make money.

But Zhang Kuang likes to solve crimes, since he was a child, he can't count how many books related to criminal investigation he has read, from suspenseful detectives to obscure professional books, he will buy every book he can find in a bookstore or online store and read it at home with hunger.

In order to become a detective, eighteen-year-old Zhang Kuang did not hesitate to turn his face with his parents, resolutely applied for the police academy, and later entered the criminal police academy for postgraduate studies, and finally graduated from the criminal police academy with the first grade in the school.

The sword that has been sharpened for many years has finally been unsheathed, and the natural edge is exposed, but the complexity of society is far beyond the school, even if it is a prestigious team, it is also sophisticated, the same intrigues, and the temper is violent and arrogant, and Zhang is not suitable for this environment after all, and he can only choose to resign.

After taking off his police uniform, Zhang Guo never solved a criminal case with his own hands, and his dream of being a detective had nowhere to put it, and his former pursuit was deceived by reality, as if he had betrayed the first half of his life.

Although former colleagues were envious of Zhang Kuang's easy work and high income, Zhang Kuang regretted it more than once, thinking that there was no other way but to return to the team and start from the grassroots level, but he didn't expect things to seem to take a turn for the better.

Since the 310 bus arson case, Zhang Guo has become closer and closer to the extraordinarily serious criminal case.

After missing out on the arsonist Qiu Yang, Zhang sighed and was depressed for several days, until the appearance of a mysterious client reinvigorated him.

This mysterious customer never shows his true face, and even the payment is settled in digital currency, making it difficult for Zhang Guo to trace his identity.

Everyone the mystery client asks him to find seems to be a party to a case or an event, whether it is a suspect or a victim.

After discovering this, Zhang Guo immediately approached his peers in Yinjiang and neighboring cities to inquire, and sure enough, they had all received similar business, and the ghostly mysterious customer was obviously related to the "black light" that had been rumored in Yinjiang recently.

Since then, Zhang has pretended not to know, but has privately begun to investigate, and he has paid attention to every unusual incident in Yinjiang City.

For example, a while ago, hundreds of private cars in the Guanshan Tunnel gave way to the passage of life in the sound of two short and one long horns, so that the pregnant women who were blocked in the tunnel rushed to the hospital in time.

This positive energy news was vigorously reported by Yinjiang TV and Handong Satellite TV, and the video of the vehicles giving way in the tunnel was even more popular on Weibo, which moved countless people to tears. With a keen intuition, Zhang realized that the incident was most likely related to the black light, because according to eyewitness accounts, someone riding a balance bike through the tunnel called for and organized private car owners to get out of the way.

After some twists and turns, combined with eyewitness accounts and videos recorded at the scene, Zhang Jing finally determined the identity of the rescuer.

It's not familiar, but it's not unfamiliar, and two of them are Xu Baiyi and Feng Hao, who have dealt with each other before.

Thinking of Xu Baiyi's rescue of An Yi and the underground den where he helped the police crack Bao Chengcheng, and Feng Hao "happened to pass by" the flying ring road and rescued his ex-girlfriend who was in danger, the true identity of "Black Light" is about to come out.

But Zhang Kuang knows that the real world is not always linked to each other like reasoning, and it may be one coincidence after another, strung by subjective speculation into the so-called chain of clues.

Moreover, with Xu Baiyi and Feng Hao's personal abilities and social relationships, how could they predict possible criminal cases in advance? What to pay for the exorbitant survey?

In addition, in addition to Xu Baiyi and Feng Hao, Zhang Kuang has other suspects, such as Han Yi, who has a close relationship with him, such as a young firefighter named Cai Chengying, and Fang Ziyu, an assistant who often releases his own pigeons recently-Fang Ziyu is the protagonist of the 310 bus arson case and the 9.16 case, and he knows Xu Baiyi and Feng Hao, so he also entered Zhang Kuang's suspicious list.

Due to the unknown identity of the mastermind behind the scenes, Zhang Guo did not startle the snake, but collected clues while probing, and continued to wait for opportunities.

But Zhang Kuang didn't expect that he would be suspected by the city bureau because of this, which is no wonder, after all, he has been actively investigating related cases, and he has this ability and motivation, so those colleagues who knew him before will naturally suspect him.

In addition to the ridicule, Zhang Guan faintly felt teased, because he suspected that it was the behind-the-scenes instigator of "Black Light" who set up the situation and let himself take the initiative to bear the black pot.

Although he didn't mind being saddled by this black cauldron, he was also determined to find out the mastermind behind the black light, so he simply put down those bits and pieces of business and concentrated on tracking down the black light.

A day ago, Zhang Kuang received a message from his personal intelligence network, which he had operated in Yinjiang for many years: Two old gangsters who had been in trouble after their release from prison were asking people about drivers who were willing to smuggle cigarettes.

After a little investigation, Zhang Kuang figured out the background of Ma Dayan and Pingtou, and after learning that the two had bought four second-hand vans, Zhang Kuang guessed their robbery plan.

Coincidentally, he happened to know a friend who ran the line from other provinces to Yinjiang. After realizing that this was an opportunity to face the black light, Zhang Kuang immediately contacted Lao He and made up an excuse to catch Lao He's truck.

Things develop as expected, Lao He is robbed by Ma Dayan and Pingtou on the provincial road, and Heiguang makes a strong appearance as a superhero, defeating the gangsters and protecting the safety of the victim Lao He.

When he saw the three men in black, Zhang Guo confirmed the identity of two of them.

Wearing a mask can block the face, and wearing a voice changer can change the voice, but if there is no professional training, it is difficult for a person to change the way he walks, and the stride, gait, and gait are also important means used by the police to confirm the identity of the suspect, so Zhang Guo can see at a glance that it is Xu Baiyi who drives the Santana 2000, and the one who talks a lot is Xu Baiyi's little brother Feng Hao.

As for who the other person was, Zhang was not sure, but he believed that he would find the answer soon, because he secretly put a monitoring and tracking chip in Xu Baiyi's car.
