Ba Shen's laughter, who knows what is hidden in his laughter, madness? Proud? Cold? Lonely? There is also helplessness and self-mockery about fate. Ba Shen is such an extreme ego, a truly free man. Ba Shen can only be evil. Similarly, Ba Shen will always be sad. Because he will always fight another self, Ba Shen who is dominated by the blood of the Eight Banners. The god of the new world, the shadow that can never be shaken off. It is precisely because of this that Ba Shen makes me even more awe-inspiring, because he dares to face up to his evil and bear the unbearable loneliness of ordinary people. How simple and ridiculous the so-called justice of Cao Zhijing and Jin was when they burst into laughter!
