I the King of bandits of the East Sea

I transmigrated into the Mountain Bandit King, Sig, and just smashed a bottle over the head of Red-Haired Shanks, one of the Four Emperors. Now I’m panicking like crazy.
What should I do? Help! Waiting online!
How do I act like someone who regularly smashes bottles over the heads of the Four Emperors?
At that moment, a goofy role-playing system was activated. The better I play the role, the more I can gain the original character's power.
And the first character card I drew just had to be King, the S-Class Hero with zero combat ability from One Punch Man!
