Kill the BOSS! You Let Me Travel Through Time

I actually wore it, but luckily I have a system Have you ever seen a god-level bloodline emerge from killing a chicken? Have you ever seen Killer Bastard explode with god-level martial arts? Have you ever seen a world go crazy because of one person? Have you ever seen someone fight across the world just to meet you again? Have you ever seen ten thousand dragons rise into the sky to fight for just one person? He has a dragon-slaying sword in his left hand, a sky-destroying sword in his right hand, and wears mixed gold armor. I just asked "**, who else?" Long Chen holds the system in his hand, comes through time, kills monsters and upgrades, kills people with upgrades, crushes everything, and destroys all those who disobey!
