Read Nuclear Slash Technique꞉ One Hit, One Kill

Special forces soldier Jin Quan is betrayed during a mission and becomes a living target to guide missiles.
When he wakes again, he finds himself in the body of a destitute man who collapsed on the streets of the Lower City—a place where the lowest class of humanity is forced into life as expendable miner-slaves.
At the brink of life and death, Jin Quan awakens the Demonic Swordsman profession, and the radiation from the dirty bomb that exploded in his past life has become his unique talent.
In this world, Jin Quan will battle against the so-called Chosen Ones.
