Origin Story
话说三国时期，关羽在曹操帐下效力时，因兄长关羽被曹操所杀，所以怀恨在心，曾暗中与刘备约定，一旦有机会便脱离曹操，投奔刘备。但是，关羽当时受到曹操的重用，曹操待他十分优厚，关羽既不好直接背叛，又担心曹操对他不信任。因此，关羽每天都更加努力地为曹操效力，希望以功劳来抵消他的背叛之心，最终，关羽凭借自己的功劳，离开曹操，回到了刘备身边。
During the Three Kingdoms period, Guan Yu served under Cao Cao. Because his brother was killed by Cao Cao, he harbored resentment and secretly made an agreement with Liu Bei to leave Cao Cao and join him when the opportunity arose. However, Guan Yu was highly valued by Cao Cao and treated very well. It was difficult for him to betray Cao Cao directly, and he also worried that Cao Cao would lose trust in him. Therefore, Guan Yu worked even harder for Cao Cao every day, hoping to compensate for his disloyalty with merit. Eventually, thanks to his achievements, Guan Yu left Cao Cao and returned to Liu Bei's side.
