"Noticed? Ao Yong said he was the first to go to the mall. ”

Li Ang raised two fingers and said slowly: "All players in the killing game have two crucial rules, one is to ensure the safety of their own lives, and the other is to hide their true identity in the real world.

One player cannot tell if another player is friendly or evil;

A player cannot tell whether another player is acting in good faith or bad faith towards him;

One player cannot judge whether another player believes he or she is acting in good faith or in bad faith;

One player is unable to judge another player judging whether he is acting in good faith or malice towards him;

One player can't tell if another player will count themselves after the mission is over;

The above lengthy and cumbersome discourse can be summed up in one concept: the chain of suspicion.

There is no guarantee that the 'teammates' they meet will be friendly, and there is no guarantee that the 'teammates' will no longer calculate themselves after completing the mission, so the player must not reveal their true identity in the real world.

There is no way to establish basic trust between players who meet for the first time, and it is necessary to get to know each other and build trust in order to dispel suspicions.

Suppose that in this mission, all players will only trigger the mission if they have been to the mall during the day.

This means that as long as you check the surveillance footage and find out the abnormal behavior among ordinary customers, it is very likely to find out the true identity of the player in this mission.

Players who are worried about their teammates' calculations, such as me, the epidemic doctor, the lost airship, Wu Xian, and Ao Yong, will pretend that nothing happened after triggering the mission during the day, continue to play the role of ordinary customers, and calmly walk out of the mall.

It is not until you leave the mall and arrive at a safe location that you will use the time between daylight and 12 a.m. at the start of the mission to prepare for the response.

For example, buying information, investigating the background of the mall, and so on. ”

"But," Leon continued, "what if Player A has already shown an abnormality in his expression, expression, or behavior when he triggers the quest and hears the system prompt?" ”

"Even if A just accidentally spills a cup of coffee in excitement after triggering the mission, or almost falls down, or drops a dollar coin while pulling out the money..."

"Player A, who appears unusual under the surveillance camera, knows that something is wrong, and out of suspicion, he quickly conceives in his mind that he has a good chance of meeting an evil player B in a co-op mission"

"Evil player B with malicious intentions can do everything as usual when performing the task, and after the mission is completed, go through the surveillance video to find out all the ordinary customers who have behaved abnormally all day today, screen them one by one, and delineate the scope."

"Compared with the hidden value of a player whose identity is exposed, the time and energy consumption of screening ordinary customers is not worth mentioning,"

"Once the evil player B finds out the true identity of player A, he can threaten the real identity of player A through the private chat of friends on the system page, and coerce player A to transfer all the game currency and game equipment to player B.

Otherwise, Player B will be detrimental to Player A's family, and so on. ”

"Player A isn't sure if the evil player B he conceived exists, and he's not sure if the teammates he and others will meet will be so evil, but he definitely doesn't dare to bet and can't afford to bet."

"Therefore, there are only two paths left in front of Player A."

"One, defect to the Special Affairs Bureau."

"Second, before the mission starts, erase the surveillance video of the day in Longheng Mall in advance, and erase all possibilities of exposing his identity."

"If you don't want to go to the Special Agents Bureau and completely separate your family and friends from society, Player A can only choose the second option."

"So, he has to move faster than the other players."

Li Ang took out his mobile phone and swiped it on the screen, "He probably won't have time to find a broker, buy hacking software, and remotely delete the surveillance video.

The quickest way is to go to the main control room and delete the surveillance video before other players hack into the mall's surveillance system. ”

Li Ang opened a certain 5:40 p.m. mall surveillance screen on the mobile phone screen, which shows a narrow corridor located in the corner of Building C of the mall, with men's and women's toilets in front of the corridor and utility rooms in the rear.

Ordinary people were going in and out of the men's and women's toilets, everything was as usual, and suddenly the surveillance screen went black.

Leon swiped the phone screen to switch to another surveillance camera's monitoring screen. This camera is located on the outside of the hallway, and the time is displayed as 5:42 p.m.

At this time, there were still ordinary customers entering and exiting the men's and women's toilets, and a security guard wearing a uniform and a mask who had not appeared in the previous picture walked out of the utility room deep in the corridor.

"Notice this security guard? The first surveillance camera didn't catch him before it failed, and the second camera only captured him walking out of the hallway.

This is clearly a customer, pretending to walk out of the bathroom, quietly destroying the first surveillance camera, then turning back, walking into the utility room deep in the corridor, taking out the security uniform from it and putting it on, and then passing the second security camera. ”

Leon continued to swipe the screen, switching camera feeds, watching the masked security guard go all the way down to the main control room on the basement floor at 5:47 p.m.

"There was no surveillance inside the main control room, only in the corridor outside, and it wasn't until 8:18 p.m. that the man, disguised as a security guard, walked out of the main control room and out of the mall gate."

Leon smiled and said, "If he is a player, why not delete all surveillance videos immediately to prevent the leakage of his real identity?" On the contrary, until just now, the monitoring system was still functioning?

Unless, he's in the main control room, something unexpected happens..."

At about 8 o'clock in the afternoon, Li Ang found the intelligence broker "Mule", and obtained the software to hack into the surveillance system from him, and spent two hours looking through all the surveillance videos from the morning to 8 o'clock in the afternoon, and found this anomaly.

However, due to the lack of intelligence at that time, Li Ang had not directly linked the man to the ghost, and even tried to open his spiritual sense to detect his teammates when he first entered the hall.

It wasn't until he and Liu Wuxian communicated on WeChat that he found that the number of ghosts was wrong, and he suddenly connected the man's abnormality with the ghosts in this mission.

"It is very likely that the man who came out of the main control room, disguised as a security guard, had already met the ghost and was murdered and killed in the afternoon,"

Li Ang sighed leisurely, "The ghost who has taken away the body naturally does not need to take into account the true identity of the original owner of the body to destroy any surveillance video."

In the killing game, killing a player can get the player's identity.

After exchanging information with Wu Xian and deducing that the number of ghosts was incorrect, I suspected that there was a ghost hiding in the team that had taken the player's body. ”
