At the beginning, my sloppy master gave me three marriage certificates.

"Me too. Although I have two assistants, the formula this time is very important, so I didn't let them interfere, nor did I let them enter my laboratory, so it is impossible for outsiders to go to my laboratory. Put on a camera!”

Li Jianxun also said.

Jiang Han frowned upon hearing this.

He thought for a while, then called up the surveillance. He looked at all the surveillance in the past month and found that no outsider had entered the research room of these two people in this month.

Just when Jiang Han was thinking, three people walked over from the other end of the corridor.

Jiang Han took a look and saw that these three people were none other than Tang Wan, Zhao Ya and Hou Donglin.

Apparently they were also interested in hearing about the progress of the investigation.

"How is Jiang Han's investigation going?"

Logan asked.

"Some clues have been found..."

So Jiang Han told Tang Wan and others about the situation he just discovered.

When these people heard this, their eyes widened.

They didn't expect that the enemy would be so powerful that they would install cameras in their researchers' laboratories!

"Jiang Han, since you have watched the surveillance videos within a month and have not found anyone entering their research room, how did the other party install the camera in our room?"

Logan was very confused.

"Do they have the ability to penetrate walls? This is simply impossible!"

Zhao Ya said to herself, obviously she couldn't understand how the other party committed the crime.

"I suggest you check out Minister Hou and his research lab. You should have the answer after reading it!"

Jiang Han thought for a while and said.

Everyone was confused and didn't understand what Jiang Han meant.

"The research room is an important part of the company. Jiang Han, you are not a member of our R&D department, so you are not suitable to go there to check!"

Hou Donglin said to Jiang Han.

"Mr. Hou, you think too highly of you. Which cosmetic product you have developed so far can be more effective than my whitening and freckle removal cream? If I can develop that product, will I still care about the things you are researching? "

Jiang Han said unhappily.

Hou Donglin's face turned red and purple when Jiang Han said it, and he was speechless.

"Let's go!"

Jiang Han glared at Hou Donglin and motioned for him to lead the way.

Hou Donglin had no choice but to lead the way.

Soon, several people arrived at the research and development room where Hou Donglin was located.

This R&D room is much larger than the two R&D rooms used by Li Jianxun and Pang Zhengliang, more than dozens of times the area of ​​them.

Moreover, the equipment inside is more complex and high-end, with several test benches. At first glance, it is the largest research room in the entire department. This research room is used by Hou Donglin and a group of his subordinates.

There is an independent research room at the end, which is three times larger than Li Jianxun's research room. It is Hou Donglin's special research room.

Jiang Han checked one by one and found cameras in the large research room outside, but no cameras were found in Hou Donglin's small research room.

Everyone's expressions were a little heavy when they saw that their research center had all been equipped with cameras!

Their secrets are transparent to each other, so how can they compete with each other!

Just when everyone was feeling heavy, Jiang Han was confused about not finding a camera in Hou Donglin's research room.

He didn't understand why Shan Shanhou Donglin didn't have it.

"Jiang Han, how should we find the person who installed the camera next? Should we first retrieve the surveillance video of this research room?"

Logan asked.

"no need!"

Jiang Han waved his hand.

"Why? Have you found the person who committed the crime?"

Logan was confused.

"Not yet, but it should be almost there!"

Jiang Han said.

"Pretending to be a ghost, if you know who it is, tell me immediately!"

Zhao Ya glared at Jiang Han and said impatiently.

"I guess these cameras were installed here when the research rooms were first renovated! Otherwise, ordinary people would not be able to enter the research rooms and would not be able to complete the work of installing the cameras!"

Jiang Han said slowly.

"It's really possible. I know why there are no cameras installed in Director Hou's research room. It's because that small research room was separated later and was not renovated in the same batch as these research rooms, so it wasn't equipped with cameras. !”

Tang Wan suddenly realized.

"It seems like this! The big research room was renovated first. Later, when Minister Hou came to see it, an independent research room was added, and then a smaller one was added. No wonder the innermost research room was not equipped with cameras, Jiang Han. It would be a pity not to be a detective with this brain!”

Li Jianxun is the leader of the R&D department and knows more about the decoration of the research room than anyone else. He immediately agreed upon hearing this.

"Mr. Tang, do you remember who was responsible for decorating our research room?"

Jiang Han asked.

"The man's name is Qi Daheng, his decoration company is called Kaihao Decoration, and its address is on Renmin West Road!"

Logan said.

"Okay, I'll go find him now!"

Jiang Han said as he stood up and left.

"Jiang Han, what should we do next? The market has to grab it back!"

Logan asked.

"You ask the workshop to make the semi-finished product according to the recipe I gave you before. Then I will come back and add a few other ingredients. There will be no delay!"

Jiang Han said and walked away quickly.

Jiang Han got in the car and rushed directly towards Renmin West Road. The research room in this new factory area was renovated more than a month ago. It should not be difficult to find a decorator in such a short time.

He had a strong hunch that this camera incident should be closely related to the masked man before. Maybe if he caught the person who installed the camera, he could follow the clues and catch the masked man!

Jiang Han soon came to Renmin West Road, where he found the decoration company called Kaihao Decoration in the middle section of Renmin West Road.

The decoration company was on the first floor, and Jiang Han opened the door directly and entered.

Several receptionists were talking to customers. When Jiang Han came in, a receptionist immediately came over.

"Sir, are you here to see the decoration?"

the receptionist asked.

"I'm looking for your boss!"

Jiang Han said.

"Do you have an appointment with our boss?"

"I work for a beauty company. You have decorated it for us before. We still have some work that we want to talk to your boss about!"

Jiang Han thought for a while and said.

"Really? Well, just wait a moment. I'll call our boss to see if he's in the company now!"

When Jiang Han heard this, he immediately became nervous. He was afraid that the boss would run away and hide again like what happened before, so that he would have to spend all his energy to find the other person.

Fortunately the receptionist's call was answered soon after.

He simply communicated with his boss on the phone for a while and then hung up.

"Sir, please come with me. Our boss is on the second floor. I will take you to see him right now."

The receptionist said, leading the way, and Jiang Han followed.

He didn't expect to find the other party so smoothly this time, but he felt a little uneasy.
