The Reclusive Assassin in the City

Zhang Hua left Star City at eighteen to become an assassin. He gradually became one of the world's deadliest killers, earning the nickname King of Hell.

At twenty-two, tired of the assassin's life, Zhang Hua quietly retired and returned to his hometown of Star City.

When he got back, Zhang Hua found that his hometown was completely different from the one he remembered. Star City had become prosperous, but also more chaotic, turning into a paradise for criminals.
