Manager Wang retrieved the surveillance very quickly. In less than ten minutes, he called Jiang He and asked him to take Tang Huanxi and others to the surveillance room.

The monitor room displays the activities of the deceased in the hotel at different times.

According to Manager Wang, the deceased was the side dish chef in the kitchen. Because he received a call from Jianghe at noon, he arrived at the hotel at around 2 o'clock.

During this period, he almost always worked in the kitchen, and the videos were recorded. He went out several times in the middle, all going to the toilet.

During the toilet, I did not contact anyone.

In addition to the chefs in the kitchen, these chefs have been controlled by Jiang He and are under interrogation.

So it is extremely difficult to get some information from the surveillance video.

"Uncle Ma, can you infer the approximate time of poisoning from the time of the deceased's death?"

Tang Huanxi frowned and stared at the surveillance camera, and suddenly turned around and asked.

Ma Wenqing pondered for a moment, then looked at his watch: "It's 8:30 p.m. Now, judging from the vomit I found in the mouth of the deceased, the time of the onset of this medicine should be about three hours."

"That is, around 5 pm, it is the time for the deceased to be poisoned."

"Change the video to 4:30, and see six o'clock ten times the speed, fast."

Tang Huanxi's tone was quick. She now knew very well that time was life. She found the source of poisoning one second earlier and found the poisoned person. The lives of thousands of employees in the venue had a little more hope.

Soon, the staff quickly played back the video, and the starting time was fixed at 4:30, and the video was played at ten times the speed.

"stop!"

At 4:58, Tang Huanxi suddenly stopped.

At this time, the deceased in the picture had just walked out of the bathroom, walked quickly through the passage, and walked into the kitchen.

"Return back and freeze when he first came out."

Tang Huanxi opened his mouth.

"good."

When the staff called back one by one, freezing the picture in the male bathroom, Tang Huanxi suddenly pointed his finger at his face:

"If I remember correctly, after he left the bathroom this time, no one had used the bathroom in the back, and no one had entered or exited."

"But you see his face when he came out, he looked back when he went out, and his expression was unstable. There must be other people in the bathroom at that time, but this person never went out through the main entrance."

Amid everyone's shocked eyes, Tang Huanxi spoke in a deep voice: "It's just three and a half hours, the bathroom, the invisible stranger, and the sudden death of this person..."

"I suspect he was the one who drugged the kitchen, but for some reason, he accidentally came into contact with the poison, which led to his early death."

"Change the surveillance video until the morning, at twenty times the speed, and put it from morning until before he enters the bathroom."

"During this period, someone must have gone in and never came out again."

As she said that, she looked at Zhang Zihao: "Now in Nandu, Bai Qiming and others need to be responsible for the guards of the research room, and you can only rely on this place."

Zhang Zihao understood it, nodded, stopped talking, turned around and rushed out.

At the same time, a figure slowly appeared in the surveillance video, attracting everyone's attention.

A middle-aged man.

"It's him, it's him!"

"Ma Wenfeng, the master of the Ma family's Poison Hall!"

After seeing this person, Ma Wenqing and his wife shouted out in shock.
