Liu Bei was originally a college student who enjoyed watching and critiquing the new Three Kingdoms. He unexpectedly traveled into the world of the new Three Kingdoms and became the expressionless Liu Bei.
Unexpectedly, this world has been corrupted by strange and bizarre rules, becoming incredibly bizarre.
In order to survive, Liu Bei had to abide by the following rules:
Rule 1: Don't let others know you are not Liu Bei.
[Rule 2: Please maintain Liu Bei's persona and keep a poker face, even if Guan Yu and Zhang Fei are eating people in front of you, you must still keep a poker face.]
[Rule 3: Each character has their own triggers. Please do not touch them, otherwise they will enter a bizarre state.]
[Rule 4: The Unstable is not invincible. After killing or eating someone, the Unstable will enter a state of arrogance, becoming agitated and thus exposing its weaknesses. At this point, the arrogance will inevitably lead to defeat.]
If the enemy hasn't been defeated yet, it means you haven't killed enough. Please stack the Pride buff on them again.
