Le Yu felt that he had discovered the Dark Qin Leyin Principle.
Known facts:
① Nieruo and Ming Shuangli were currently the sword-scabbard trainer duo with the greatest advantage;
② Youth Mietangya lived in the student dormitory, had roommates, did not live alone, and held a relatively low position in the academy (a first-year student);
③ Teacher Qin Leyin lived in the teachers' dormitory, lived alone, held a relatively high position in the academy (a teacher), and was not weak.
Once Le Yu stepped outside the situation, he could see that among the three exposed sword scabbards, Qin Leyin was indeed the best partner: Nieruo was too strong, while Mietangya was too weak. By partnering with Qin Leyin, who ranked second, they could advance and defecate on Nieruo's head, or retreat and defecate on everyone else's head except Nieruo's.
The sword scabbards weren't idiots. Le Yu reckoned that someone like Mietangya, who actually claimed that Honey Five-Flower Tea tasted bad, probably represented the lower limit of intelligence among the sword scabbards. Yet even Mietangya could draw three conclusions from the information above:
① Partnering with Qin Leyin was the decision that maximized their benefits, and it was also a necessary condition for their side to become the biggest winner in the All-Knowing Eye examination;
② If they didn't partner with Qin Leyin, they would inevitably be suppressed, bullied, and victimized by Qin Leyin's team.
③ Partnering with Nieruo was like bargaining with a tiger for its hide, while partnering with Mietangya would be futile, because Mietangya's team most likely wouldn't be able to defeat Qin Leyin's team.
Thus, every sword scabbard reached the same conclusion: find Qin Leyin and cooperate!
This was the Dark Qin Leyin Principle. If you didn't want to lose, you could only become Qin Leyin's accomplice!
