Hakai Me no Yuuri - Chapter 30: Tidying up

A letter to break off the engagement leads Ling Family in Tangyang to endless doom. And he, Ling Zhang, is tortured to death after his legs are cruelly broken.

A modern-day antihero, who was infamous for his devious acts, dies in an explosion meant to take down a powerful criminal syndicate.
