In the battle earlier, Hao Ren was not just standing there like an idiot, tanking blast after blast. All right, it may have looked like that, but Hao Ren was no slouch. With the MDT's help, he swiftly collected all sorts of data on the goddess of annihilation, from her attack patterns to her strengths. With every move she made, there was a "rotation" that she would fall back to, and all this information was collected. The reason for this was, he truly believed in one sentence that Raven 12345 once told him; even though the goddess spewed drivel most of the time, this particular sentence was convincing.
This was what she said, "Hao Ren, you know, even for the gods, their actions are bound by a certain rule or pattern just like how I love to chomp on noodles. This is the rule of the gods."
Frankly speaking, if not for that last part, he would have probably forgotten about it.
