Thanks for the upload, hm... not the flashback I was expecting but I like this he was fascinated by humanity's fights and inspired to an extent where he could no longer be satisfied to just sit and watch and then cart the loser away. He wanted to break the pattern or routine and experience it for himself. Good for him, and I see he embraced the Capaldi method of training. Though I was partially expecting an easter egg type of gag where he was the grim reaper tasked with retrieving Lu Bu's opponents.
