Su Ruifeng appeared on the top floor of an office building.

The top floor looks like the office of a decoration design company, but it is actually a secret office of Guoan.

There are many more places like Guoan.

At night, many offices in this office building are brightly lit, and people are busy working in front of computers. The work pressure in big cities is really too great.

However, in this case, the seemingly busy "decoration design company" on the top floor is not so eye-catching.

This company really looks very real, and even has the front desk.

"I'm looking for Wang Zelong." Su Rui said directly to the front desk.

The receptionist took a deep look at Su Rui: "President Wang is here, please follow me."

Following the receptionist, Su Rui entered a conference room, where Wang Zelong was tapping into a notebook. Seeing Su Rui coming in, he immediately said, "brother Rui, sit down first, Yu Lingling, pour a glass of water for brother Rui, and then give brother Rui a detailed description of our main investigation."

It seems that this receptionist is also a national security agent.

"OK."

Yu Lingling brought Su Rui a glass of water and turned on the projection.

At this time, a very detailed choroidal network appears on the projection.

Every node on this network is a person's name. After the person's name, there are small parentheses, in which a brief introduction to the person is added.

"Very detailed." Su Rui said, "everyone, it's hard."

"In fact, it is also done incidentally. If the murderer can be found out, it is to eliminate the harm for the people." Wang Zelong said modestly.

He said that the clouds are light and the wind is light. However, after less than a year of investigation, such a detailed network of veins has been sorted out. The hard work behind it must be beyond imagination.

If nothing happens, Wang Zelong's future in Guoan must be extremely bright.

Yu Lingling began to give Su Rui a brief introduction to this venation network.

"Through investigation, we found that the messenger behind is very cautious and constantly changing the direction of the clues. It is reasonable that normal people have no reason to do so. This is not a major murder, and there is no need to cover up the truth with many false clues." Said Yu Lingling.

What she said was also a problem that had plagued Su Rui before.

According to common sense, Ke Ning's case is very simple. As long as you follow the trail, you can find the main culprit behind it.

Over the years, Ke Ning has been subjected to countless difficulties. Whenever she works in an enterprise, that enterprise will certainly be maliciously destroyed. In this case, Ke Ning has no place to stand in Yizhou. For the safety of her family, she had to hide her name and go far away from Yuanjiang City.

That can make many people amazing appearance, but brought her unspeakable nightmare. If Su Rui didn't get the information provided by Su infinite and appear in time, he might not wake up from the nightmare, but fall deeper and deeper.

Those thugs who beat, smash and rob are easy to find, and those who bully Ke Ning's family can also be easily caught. However, as soon as they are pressed to ask who ordered them, these people don't know anything.

Clues are always so easy to break.

Whenever Su Rui focuses on those clues that seem very obvious, he is almost faced with a situation that cannot be traced.

"Ke Ning was constantly harassed, but those thugs didn't know the situation." Yu Lingling said, "they all collect money to do things, but the person who gave them the money couldn't be found in the end. It's been too long, and the contact information and so on don't exist."

Su Rui squinted: "go on."

In his view, there are three reasons for those behind the scenes to do so.

Su Rui nodded, and then his eyes released a fine light: "don't worry, he can't run."

At this time, a flash of light flashed through Su Rui's mind. He suddenly thought of something and hurriedly said, "I'll take a look at the surveillance picture just now!"
