The mysterious dragon figure in Jiangnan speculates that Mr. KFC and the headmaster, the only people who came back after the mission failed 0/0 years ago, have not seen Lu for a long time.

First of all, the analysis of the survivors of the mission ten years ago: I personally think that the principal should be excluded first, because according to his behavior when he visited the ice room, we can know that he did not participate in the fight, but the survivors took part in the fight with KFC bags (from the comparison between Eva's reminder and the person holding KFC bags), and the rest were the vice principal and fingers. It is doubtful that the fingers were buckled due to work-related injuries. However, Finger only studied in Kassel for nine years, and the principal said that he was once an excellent A-level. This shows that Finger was insane in an accident within 9 years, so Finger was excluded. Only the vice principal is left. The vice principal doesn't often come forward, and his age can be reasonably explained, but he may have accidentally used KFC's bag in the ice room. Moreover, from the part after the auction, Mr. KFC only occasionally uses KFC paper bags, which is not a status symbol. Next, the owner of the icehouse came forward to prove that the owner and the survivor were not the same person.

Secondly, Mr. KFC, from the above analysis, we can see that except for the finger, the principal and KFC should be antagonistic. From Lu's mental description of returning home, we can know that Finger was at school at that time. But it is possible that the vice principal is a spy.

Then there is the boss. We know that Lu has no entity, and it has left almost no trace in reality after devouring Ricardo Milu's life, so we ruled out the possibility of Lu. From all aspects, it can be seen that the principal and the principal are antagonistic, so the principal is excluded. Caesar regarded Ricardo Milu as his brother, so he ruled out Caesar. Chu Zihang was set up by the boss and others, so Chu Zihang was excluded. The vice principal has little to do with Ricardo Milu, so the vice principal is excluded. So the boss is a person who has no clear positioning. He may be on the same side as Lou Ming Ze, or he may just want to help Ricardo Milu. The identity of the boss is temporarily unknown.

Why did the headmaster say it had been a long time? According to the previous entrance examination, he was not talking about Ricardo Milu. Then there is Lu. According to Ricardo Milu's memory, Lu may be a dragon, so the headmaster who buried the dragon is opposite to Lu. According to the prequel, the headmaster once met a dead dragon, so it may be it. Because the headmaster is a dragon mourner, he wants to kill the dragon he didn't kill. He slaughtered the principal's partner, so the principal wanted to see him early and kill him. Because the number of dragons encountered by the headmaster in his life is unknown, he can only make such a tentative guess.
