Ye Weiming told his teammates to make Xiong Ba so easy to kill that he's practically worthless, and he wasn't simply talking nonsense out of blind confidence.
It's because...
...he's dealt with the System so many times that he understands its mechanics inside out!
Firstly, though the System is deceitful, it also follows certain principles. The task difficulty ratings it provides are generally accurate. If a straightforward task becomes difficult, it usually means you're not approaching it the right way.
This time, since the System defined "blocking Xiong Ba" as a seven-star mission, it means that for current players, it shouldn't be too challenging.
Moreover, this mission has no special tricks; you just have to charge forward.
This implies that Xiong Ba's strength is likely nerfed.
Then there's the equivalency between effort and reward, which has been validated multiple times. It's proven to be real and effective.
