Green Plum, Warm Liquor is another Wo Long: Fallen Dynasty stage where you need to defeat a former ally as training. However, unlike Zhao Yun, this fight can be cheesed with the right tactic.
How to Defeat Cao Cao in Wo Long: Fallen Dynasty
Since this is just a boss fight, make sure to have a fast weapon ready.
Defeating Cao Cao
Similar to the first boss, Cao Cao can be stun locked by simply attacking him. While he will break free with critical hits, this is commonly a dash that goes straight, and has a really easy deflect window. I actually had no issue mashing attack, waiting for the glow, and just dodging as soon as I saw it for the deflect.
In the event this doesn’t work, simply go on the defensive and wait for critical hits to deflect.
