^^This.

Issei and the others are Devils, Angels, Fallen Angels, etc. For a human like Cao Cao who can't even use magic, demonic power or some mythical abilities, what do you suppose he should do, just attack blindly with a spear, he wouldn't last a second. In the end, for Humans like Cao Cao all they can do is to use the opponents weakness to fight back. Plus, you think Cao Cao's powers can be so easily used, Cao Cao polished his techniques to the fullest, what's the point of his training with all that technique if he can't use it.

In the end, it's Cao Cao that is skilled in using his spear and the ORC + Vali Team's error of underestimating Cao Cao.
