Hans always believed that he would wait for the Revenge Shadow Rider, waiting for the once every four years world-class Ancient Martial Arts festival for the Revenge Shadow Rider to reappear on earth.

Of course, this doesn't mean First-Order warriors are weak; quite the opposite, these individuals are already very strong. However, circumstances forge heroes, and compared to the stellar array of the Drifting Epoch, today's experts are indeed not worth mentioning in people's eyes.
