At eight o'clock in the evening, Hua Qing came to the Supreme Cafe alone.

Compared with the last time, the atmosphere in the café seems to be much more solemn, and there are waiters with serious faces standing in all corners of the hall on the first floor, and waiters standing in other parts of the hall in an orderly manner.

Their clothes are uniform, their hairstyles are uniform, their tallness, shortness, fat and thinness are uniform, their standing postures are uniform, and even the expressions on their faces seem to be carved out of a mold.

These waiters, apparently well-trained, did not look and look like a waiter's style, but more like a bodyguard or thug, and from where each of them stood, they could see the entire hall.

But instead of scanning the hall, they each stayed where they ought to be, staring intently at a certain place, as if they had been assigned in advance.

These waiters are not like normal waiters serving tea and water, their only mission is to stand in one place and watch.

Shuttling around the hall were several female waitresses, all of them seemed to be very nervous, and when they saw Hua Qing come in, the waiter closest to the door even showed a trace of horror in his eyes.

There weren't many people drinking coffee in the hall, Hua Qing roughly counted, that is, twelve or thirteen people, and there were not as many waiters standing in the hall.

Seeing Hua Qing, a waiter nodded at him, and then guided Hua Qing to sit down in an empty seat, the waiter's moves and styles were not as polite and thoughtful as ordinary waiters, although they also smiled, but that kind of laughter was stiff, and there was even a murderous aura in it.

Hua Qing walked slowly to the position of the waiter's guidance, as if looking around absentmindedly, the waiter looked at him vigilantly, until Hua Qing sat down, and the tense expression on his face was somewhat soothed.

But he didn't go far, but returned to the position where he was standing just now very mechanically, without any difference, and then half-hooked his head, looking at Hua Qing without blinking.

Hua Qing looked around, and the waiters in other places were the same, standing in their fixed positions, staring at the guests next to them like torches.

Hua Qing thought to herself, no wonder this place is deserted, drinking coffee here is simply a sin, who likes to be stared at in their leisure time.

The guests, drinking coffee as if they were drinking cold water when they were thirsty, hurriedly drank the coffee that was served, and then left in a hurry, and when they walked out of the café, they all looked behind them with a confused expression, as if they were afraid of being targeted by the waiters.

After a while, the entire hall was empty, and in the empty hall, except for those waiters with bright eyes, only Hua Qing was left.

Hua Qing took the coffee brought by the waiter, leisurely savoring it, but his eyes kept touching around, and inadvertently, Hua Qing found that at the staircase leading to the second floor, there was a kind of fire like an electric arc, flickering regularly and intermittently.

Hua Qing pretended to be curious, approached the staircase step by step, and when he approached him, he found that it was not an arc light, but a light that seemed to emerge from the ground.

Hua Qing was about to step up the stairs, but was stopped by a waiter, the waiter stretched out his hand and lightly blocked, Hua Qing suddenly felt a very powerful force hit his chest, Hua Qing involuntarily retreated.

"It's being overhauled up there, and no one can go up there." The waiter's voice was hoarse and heavy, and a little fierce, Hua Qing had to turn around and return to the position just now.

Hua Qing sat down again, slowly swallowing his coffee, rolling his eyes and peeping, he found a very interesting phenomenon, although the guests were gone, the waiters were still staring at their original positions motionless, like puppets.

Hua Qing also found a little strange situation, the line on the first floor has obviously been reinstalled, and it is likely that one or several new lines have been added, because it is a temporary installation, and the line is only covered by a wooden wire box.

Hua Qing found that those wooden wire boxes were very rough installed, obviously not the work of professionals, as for the degree of roughness, Hua Qing couldn't see clearly, he sat in the middle of the hall, far away from the walls on both sides.

Whether there are wires in those wooden wire boxes or not, and what they are for, Hua Qing doesn't know.

After sitting for about an hour, Hua Qing had no choice but to stand up, the guests who entered the café had already come and gone several times, all of them came and went in a hurry, Hua Qing would definitely be suspicious of those waiters if he delayed here.

Walking out of the café, Hua Qing raised his hand and looked at his watch, at nine seventeen, the time he entered the café was eight and seven, Hua Qing calculated, he stayed in the café for exactly seventy minutes.

Hua Qing strode forward, without looking back at the back, until he reached the darkness, Hua Qing turned around and looked in the direction of the café, and found a pair of vigilant eyes under each window looking in the direction of his walk.

Two waiters also walked out of the café and stood motionless at the door, looking in the direction where Hua Qing was standing.

Hua Qing had no choice but to continue walking, until he was completely out of their field of vision, Hua Qing stopped, stood there and thought for a long time, and then quietly dived back.

Hua Qing lurked more than three hundred meters away from the café, where there was a bush, just enough to cover Hua Qing's body, and the field of vision was also very wide, and he could see every move at the door of the café clearly.

After Hua Qing lurked, he never saw anyone enter or leave the café again, and the two waiters were gone, and they must have returned to the café.

At ten o'clock, the waiters in the café began to change their guards, and their way of changing their guards was very peculiar, not like a normal change of guards, but a change of guards one by one.

First of all, a waiter comes out of the café, and when he walks to a fixed position at the door, he greets one from the outside, and they seem to exchange something, any two people talk a few words, and the person who leaves work can only leave after watching the person who goes to work walk into the café.

The whole process of changing the guard was meticulous, and it took 23 minutes for all personnel to complete the change of guard.

During this period, Hua Qing has been counting carefully, a total of forty-six waiters have walked out of the café one after another, and forty-six waiters have walked in, corresponding one by one, tightly.

In addition to counting the number of people, Hua Qing also did one thing, that is, the entire process of changing the guard of these waiters was filmed with a high-definition camera, Hua Qing turned it out and looked at it, the clarity was okay, and he could basically see the faces of the laid-off people clearly.

Before coming to the café, Hua Qing had already prepared all the equipment, in addition to the camera, Hua Qing also prepared a bugging device, all of which were placed in the bag he carried with him.

Today, those waiters were staring very closely, Hua Qing had never done such a thing, and he was a little scared in his heart, so he didn't put the eavesdropping device in.

Now that the changing of the guard is over, the door of the café is suddenly quiet, and not a single customer enters or leaves the café.

Hua Qing thought to herself, what were the waiters who had just changed their guard doing at this time? Will you be staring intently at where you should be staring as you were just now?

Hua Qing's curiosity came up, he tiptoed forward, and just walked out about two meters, when he suddenly felt as if there was movement behind him.

Hua Qing was about to turn back, when a big hand like an iron tong suddenly lifted his arm, and the other hand suddenly locked his throat, Hua Qing had a feeling that he was about to suffocate.
