If Everyone Calls Me a Devil, Then I Will Kill All the Immortals in the World

[Fantasy] + [No heroine] + [Dark and decisive] Some people, in the name of immortals, are doing things like killing people, and they have a beautiful name: subduing demons and defending the way! Some people were given the name of demons after being massacred by so-called immortals! There are also people who, amidst repeated injustices, turn into demons. Human legend: "The devil doesn't care about human affairs, he only kills the feathered immortal from high heaven!" Is it a demon? Is it a fairy? I can't tell the difference! "From now on! I, Zhou Tong, transform into a demon and vow to kill all the immortals in the world!" "I, Xu Jing, swear to be incompatible with the immortal way!" ... The boy who transformed into a demon gradually became the nightmare of immortals during his crusade across the world! "From now on, there will be no more Han Yu in the world, only me, Han Luxian. If I don't kill the hypocritical immortals in the world, I will never enter reincarnation! I will eventually suffer the pain of hell!" "Han Luxian! He started at a young age and killed all the immortals in the world. Later generations called him the Immortal Killer Demon Lord!" Is it a fairy? Is it a demon? "Since we can't tell the difference, then I will create a world with only demons!" "Hahaha!" Fairies and demons!
