Unbounded Killer

Ye Jun, the king of killers, has encountered the biggest challenge since his debut. How can a mortal kill the immortal monster? If a killer embarks on the road of cultivating immortality, can he really become a peerless killer who can "kill one person in ten steps and leave no trace in a thousand miles"? Monsters and demons appear one after another, and a conspiracy to destroy the world is brewing. Can Ye Jun turn the tide on his own? When the end of the world comes, will it be technology or gods that will save hundreds of millions of lives? Is the killer passionate or the killer ruthless? Love and hate, love and love, are all emotions the killer's fatal weakness? Heaven is ruthless. When a killer joins forces with Heaven, can he cut off love with his sword and become a desperate killer? Let's see how Ye Jun climbs to the top step by step from thousands of worlds, killings and being killed that never change across time! This is a fairy tale of a killer. From the King of Killers to the God-King Killer, I am a killer, who should I be afraid of? When I encounter demons, I will kill demons, when I encounter gods, I will kill gods. In a billion world, who else would I be afraid of?
