I Was a Famous Teacher in the Three Kingdoms

Lin Chuan traveled to the Three Kingdoms with the character attribute panel. When giving Lu Bu some martial arts advice, one point was deducted from his intelligence and added to his bravery. In an instant, I had an epiphany, and my strength was beyond the limit. When he taught Zhou Yu the art of war, he deducted a point from his bravery value and added it to the military aspect, directly beating Zhuge Liang. When explaining domestic affairs to Cao Cao, he deducted a little from his diplomacy and added it to government affairs. After that, Cao Cao wanted to reform. I just talked casually and added a little bit to them. What happened to these people? How could I dominate when they called me teacher?
