1, there was no quarrel on the train.
Because Mr. Liu bravely helped everyone when he first met the bat, because of his age, Chen Li made a decision to let everyone elect him as the custodian of the train key, but Chen Li and others did not abide by the existing agreement and wanted to leave early. Although Mr. Liu refused, he didn't try so hard as when he grabbed cookies in the supermarket. I wonder if anyone noticed Mr. Liu's eyes when he handed over the key. It's not like the timidity and worry after being threatened, but the joy of being recruited.
2. Take the initiative to find food and compressed biscuits with Chen Li.
At the railway station, Mr. Liu should know that Chen Li is a typical egoist, completely violating the principle of the supremacy of the collective that he agrees with, and just threatened him on the train. He also offered to look for cookies with Chen Li. I don't know what kind of mentality this move is out of.
After that, four of them went into the supermarket, and the other three were still looking through the goods on the shelves in front of the supermarket. He went into the innermost part of the supermarket alone and found compressed biscuits. It is precisely because of this compressed biscuit that Chen Li and Luo Ran really formed an antagonistic situation, which led to the later story.
3. Give up Luo Ran and choose David Li Chen.
Whether Chen Li and others returned to the hotel with guns or Luo Ran returned to the hotel after recovery, Teacher Luo, who had been bullied by Chen Li, always chose to stay in the hotel, stay with Chen Li and choose Chen Li as the boss. This move is very strange. Now that I think about it, the first reason why Mr. Liu did this is because Luo Ran could be detected by the police, and he was worried about exposure, so he didn't have much contact with Luo Ran. The second possibility is that he is the boss behind the scenes, so it is natural to observe and collect data from more people, most of whom are on Chen Li's side.
4. Career problems
Mr. Liu used to be a math teacher and has a lot to do with this game. Although he has retired, it can be seen from his ability to accurately remember the rest of the staff and accurately calculate the number of cookies that everyone can get. His computing ability has not regressed at all, which proves that he has been using it.
During Luo Ran's absence, Mr. Liu and Jiang Xue, a computer major, studied the sound waves that attract bats. It is because of the help of Mr. Liu that everyone was able to eradicate bats smoothly.
I didn't explain that I used to work here.
The suspicion of Miss Liu started from this point. Miss Liu never took the initiative to explain, nor did she show her familiarity with this place. Although Jiang Xue only talked to Luo Ran, from the beginning, she took everyone from the hotel to the hospital now, which revealed her familiarity with this place. When everyone was desperate, Mr. Liu was always ready to help others, but he didn't use his experience of living here to help everyone. It was not until Jiang Xue and Luo Ran found Mr. Liu's file that he admitted that he had been here.
Although a number of data show that Nana's background is called? Ai, but the person who started this Ai is probably Mr. Liu, so I think Mr. Liu is probably the big boss.
