Since ancient times, every hero who managed to achieve something great has possessed an exceptional "persona."
A good persona can rapidly establish a personal image, gain others' recognition and affection, showcase a unique flair and charm—the benefits are endless. The most classic example is Liu Bei, Liu Xuande.
Lord Xuande was magnanimous, treated people with tolerance, was good at listening to others' opinions, deeply respected talented individuals. Although his martial skills weren't remarkable, nor was he especially clever, his abilities were pretty average compared to the other heroes of his era. But he won at being "sincere." As a lord, he was incredibly successful. Just by grabbing someone's hand, eyes red with tears, sighing, "What can I possibly do?" he could instantly arouse a powerful urge in his subordinates to protect him. Thus, his advisors would devise strategies, his warriors would sacrifice themselves, and his enemies would end up keeling over dead on the spot.
