im still referring to the escaping possibility btw,not the win win scenarioIt's not a contradiction.
We dk how the fight has ended up.
Tao could have just sacrificed himself to save Chao(give him time to escape)
But the author confirmed that Caihong is definitely way stronger than any PX in existence since she's way stronger than Chao.
The fact that Chao fled DQ isn't an indication of his power level since the fight happened offscreen so it'd be just speculation.
