In the monitoring room, Tang Zhihang had just gotten permission from Yang Zilang, and now he was checking the surveillance alone inside.

The time began when Tang Zhihang left the laboratory - he had checked the blood in the safe when he left the laboratory before, which means that the blood was stolen only from the night before yesterday to today.

Tang Zhihang used double speed to check the surveillance, and then saw someone approaching the laboratory at eleven o'clock last night.

The figure...... Who is it? I don't know, a stranger. Tang Zhihang enlarged the picture, but he still couldn't see the other party's face clearly - not because the picture quality of the monitor was not good, but because the other party's face was hidden under the hat, and Tang Zhihang couldn't see it at all.

"Tsk......" Tang Zhihang reached out and clasped his ears, since there is no way to see the other party's appearance, he can't investigate, right?

On the surveillance screen, the man in the hat pressed his hand on the door of the laboratory - the door that only Tang Zhihang and Yang Zilang's fingerprints could open was opened like this!

What's going on! The door that only he and Yang Zilang could open was opened by someone else like this...... Who is this person? It definitely won't be Yang Zilang, after all, Yang Zilang's body shape is far from this person, and no matter how you think about it, it can't be Yang Zilang.

Tang Zhihang couldn't help biting his fingernails, this was not his habit, he just suddenly wanted to bite it.

"Since it's not Uncle Yang...... Who could that be?" Tang Zhihang felt that there should not be a problem with the system, but he still decided to go back and check it just in case. But until then, he had to continue to watch what the other party did.

Not long after, the man came out of the laboratory, and there were two test tubes in his hands—naturally Tang Yihan's blood.

Tang Zhihang watched the man walk into the elevator, adjusted the surveillance screen to the elevator, and then the man pressed the button on the top floor.

Why is it the top floor? Shouldn't you go to the first floor at this time? Escape from the top floor after stealing something...... Is this guy a monster thief with a glider?

Seeing the elevator go straight to the top floor, the man stepped out of the elevator and came to the door that led to the rooftop, and then ...... The door is opened!

Tang Zhihang's eyes lit up, there were only a few people who could open the rooftop door, and among those people, the body shape was like this...... Except for Bao Yuyun, no other person in this company who can open the rooftop will be of this shape!

Watching the other party walk out of the rooftop and close the door, there is no way to see the inside because there is no surveillance installed outside.

Tang Zhihang gritted his teeth and rushed out of the monitoring room, and now the only prisoner he could think of was Bao Yuyun, Tang Zhihang wanted to catch Bao Yuyun.

But if you think about it carefully, you don't have any evidence, and you can't completely determine that the prisoner is Bao Yuyun.

Besides, why did Bao Yuyun steal Tang Yihan's blood? Or did it be Xu Yiqing's scheme? What special means did Xu Yiqing use to make Bao Yuyun steal Tang Yihan's blood......

Speaking of which, the house was also stolen, and the stolen drawings were added to Tang Yihan's blood...... Although I don't know who did it, Tang Zhihang probably knows what the other party's purpose is - to make hoffnung.

Tang Zhihang was even more anxious, it would be bad if the other party made Hoffnung, and what was even worse was that the drawings and Tang Yuhan's blood were sent to the queen and sent to destroy.
