Cataclysm Card Emperor灾变卡皇

His total disregard for his life.
At first, it was cool how he fought without carrying about his life. However, it was all ruined when he kept fighting death battles every other chapter and repeatedly used the Forbidden Healing Technique more than HP Potions, he literally used up all his lifespan once.

I managed to cope till then, but just after he barely managed to aquire the extremely rare world class treasure to recover his lifespan. He restarted using the forbidden technique in a few seconds, his excuse being that spending lifespan doesn’t matter if he can shine in dangerous battles but out of five people fighting same battle, he was the only one wasting his lifespan for every single injury.

Later, he participated in numerous death battles which had nothing to do with him and those enemies were 2-3 ranks above him, spending lost of lifespan in the process. The most ridiculous part is he doesn’t even search for treasures that can increase his lifespan because he doesn’t CARE about his life
