Okay... Someone get the writer off the booze or something. He's been fighting 4th realm rebirth cultivators for a loooong time now. Why did they act as if that was some huge reveal? They even said the old demon had the strength of a 7th realm rebirth cultivator and he won BEFORE he advanced.
Yeeah I'm slightly lost on that two, he could defend against one with strength alone previously, maybe it has something with seals he had one him? lloll or simply put the wrong layer
