Just for fun;

In LOCH, it is said that: No matter how high Huang Yaoshi's martial arts, he cannot possibly withstand the combined attack of Ouyang Feng + 4 Masters of Quanzhen.

Before that, it was said that: No matter how high Huang Yaoshi's martial arts, he cannot possibly match the power of 2 Zhou Botong's.

So it seems, there are at least 2 opponents that even if Huang Yaoshi were 10,000,000,000 times stronger, he cannot possibly hope to overcome. What if these 2 infinitely strong opponents were pitted against each other? You decide.
