Du Feng called up the monitoring screen in the emergency channel, and with the help of the emergency lights, he could barely see the figure of the black shadow clearly.

The black shadow is wearing a set of night clothes, with a black hood on his head, he is short and thin, he can be judged to be a man, his movements are very smooth, and he can also avoid so many surveillance, his skills are excellent, his strength must be strong, and he must have received professional infiltration training!

Du Feng was interested, in fact, even if Du Feng came at seven o'clock in the morning, he could still find this person through the concealed monitor, but at that time, Du Feng had only one choice, that is, to kill this invading enemy directly. However, now, Du Feng wants to see what the purpose of this man in black is.

It stands to reason that the Scorpion Organization has already arranged Liu Rong's killer weapon, and if an assassin is still allowed to infiltrate the assassination, it will be somewhat unnecessary. Du Feng suspected that this black shadow might be someone sent by the poison emperor in Europe. Du Feng has dealt with the European Poison Emperor, and the Poison Emperor's caution is notoriously known, even if Du Feng has exhausted all his methods in Europe, for most of the year, he still hasn't found out the Poison Emperor, and even only knows that the Poison Emperor is a woman! Therefore, it is very likely that the Poison Emperor will make preparations with both hands, and before the Scorpion Organization has succeeded, he will appoint another group of people to kill him.

Du Feng took out the special mobile phone, pressed it a few times, and the screen of the mobile phone appeared in the monitoring, and then Du Feng turned off the computer and left the investment promotion office.

Du Feng still walked up the stairs while looking at the surveillance screen on his mobile phone. No matter how agile the black shadow is, after all, it is in the elevator shaft, hanging a Range Rover to climb up, the speed is not as fast as Du Feng, Du Feng came to Lu Yun's floor first.

The Poison Emperor has only one goal, that is, Lu Yun, Lu Yun has mastered the development plan of methamphenylacetone, and as the most important element of hallucination, the rise of Jumei Biotech, this successful development plan is only owned by Lu Yun. Lu Chenglin, who has long been out of the world, has not asked, and Lu Yun will not be stupid enough to tell others about this plan. After the Poison Emperor knew that metholphenylacetone had been developed, he deliberately sent manpower to understand all this, so as long as Lu Yun was killed, the Poison Emperor's goal had been achieved!

Du Feng first came to the security office of Lu Yun's office floor, where he found some spare hidden monitors, and saw that the black shadow would take a while before he could come to the floor of Lu Yun's office, Du Feng quickly installed monitors in the corridor, kitchen, and Lu Yun's office. After that, Du Feng hid at the top of the stairs, quietly waiting for the black shadow to appear.

In less than five minutes, there was a soft sound from the elevator, and through the surveillance screen, a black shadow was seen opening the elevator door with a small shovel.

There were two monitor cameras in the corridor with shaking heads, and the black shadow that opened the elevator door, clinging to the entrance of the elevator, stretched out a small mirror and looked at the situation in the corridor. After figuring out the monitoring range of the two monitors, when the lens of the monitors left the elevator, it quickly rushed out, beating like a dancer without musical accompaniment in the corridor, and came to the door of Lu Yun's office.

The door was closed, and the man in black wasn't ready to open it and break in. A long strip of metal was pulled out of his body, and he took it and peeked through the crack in the door below.

Du Feng saw through the monitor installed in Lu Yun's office that after the metal 'stick' penetrated into the room, it was bent and extended to the doorknob before it stopped bending, and then the metal stick turned slightly and stuck to the wall next to it, and then retracted again.

After doing all this, the black shadow looked behind him, and then returned to the elevator entrance, and when the elevator door was closed, Du Feng came out of the staircase and ran to Lu Yun's office, after opening the door, he poked his head out, and glanced at the place where the metal stick stayed before, and sure enough, he found a small black spot on the wall.

This metal stick is a commonly used tool for special forces to detect enemy movements in rooms where they are defending, and can also be used to place small monitors and listeners in unoccupied rooms!

Seeing the monitor attached to the wall, Du Feng smiled. This proves that this person is not another team of people appointed by the Poison Emperor, but a cautious scorpion three factions to monitor whether Liu Rong has made a move and whether there is a guarantee of success!

Looking down at the phone, in the surveillance screen, the man in black went down very quickly, and he was about to reach the location on the second floor.

Du Feng immediately closed the door, sped up, went down the stairs, and when he was approaching the second floor, he saw that in the surveillance screen, the man in black appeared at the staircase on the second floor. Du Feng immediately slowed down, controlled the footsteps, and slowly walked down. At the same time, the hidden monitor screen on the second and first floors has been adjusted.

After a while, the figure of the man in black appeared in the surveillance screen, his footsteps were basically absent, and Du Feng did not hear footsteps in the stairwell on the third floor.

Du Feng saw the man in black walking downstairs from the surveillance screen, and immediately followed. The man in black would never have thought that he would be followed by a person.

Du Feng's tracking methods are very superb, and he will not keep an eye on the man in black, glance at it from time to time to confirm the actions of the man in black, and then find a favorable position and continue to track.

The man in black went directly to the underground parking lot, stopped in front of a fire hydrant without any monitoring equipment, skillfully opened the fire hydrant, took out clothes and pants from it, and a schoolbag, after changing into clothes and pants, he stuffed the black clothes and the hood into the schoolbag, and then passed through the monitoring blind corner and came to the iron fence door at the entrance of the parking lot. There are two ways to open this iron fence gate, one is remote control, and the other is in case of emergency, when the remote control cannot play a role, the iron fence gate is raised through the switch next to the iron fence gate. The man in black used a manual switch to gently raise the iron fence door by about half a meter, and then pressed the close button, and when the iron fence gate was slowly descending, he rolled on the spot and rolled out from under the iron fence door.

After that, the man in black who had changed his costume glanced behind him uncomfortably, and only after making sure that no one noticed it before quietly leaving.

Du Feng was not in a hurry to keep up, and there was a hidden camera he had installed outside, and he saw the man in black leaving from the right side of the entrance after changing clothes. Only then did he come out, and he directly pressed the button that made the iron fence door rise, and he didn't close it, but rushed out directly, and followed the black-clothed man from a distance.

After changing clothes, the man in black has been walking on small roads and alleys, but he has not left Jumei Biotechnology Company for much distance, and about half an hour later, he came to an urban village area. This urban village is called Zijun Village, which used to be a small township, and then the city planned to this side, and the new city appeared, Zijun Village did not negotiate with the local residents because of the compensation for the demolition, and finally a large part of the town remained here and became an urban village.

Because it is close to a large office building such as Jumei Biotech, this urban village has become a rental place for some office workers who do not have money.

In the urban villages, several of the breakfast shops have opened their doors and are tidying up their storefronts. The time was half past four. After changing clothes, the man in black came to a steamed bun shop, and the boss greeted him very warmly, and his name was loud, as if he wanted to tell his competitors that his business was booming.

"Xiao Wang, it's the night shift again? I remember you just worked the night shift yesterday?"

The black one, who is called Xiao Wang, said with a smile: "Yes, we can only listen to the boss in this work, and the boss said that if you work the night shift, you can only work the night shift." Okay, Boss Sun, I'm very tired, hurry up and prepare two meat buns for me, a cup of soy milk, I'll go back and rest!"

Boss Sun said: "Okay, the soy milk is also freshly squeezed, but it's sweet!"

As he spoke, he kept moving his hands, sandwiched two hot meat buns for Xiao Wang, filled a cup of soy milk and handed it to Xiao Wang. As a result, he shouted for four yuan: "Go slowly, go slowly!"

In order not to let this Boss Sun see him, Du Feng could only walk quietly in the street opposite that had not yet opened, still following behind 'Xiao Wang'.
