Cultivator Leveling Up In Apocalypse

Xian sebastian was a 18 year old boy from blue planet. One night, he was just sleeping. When suddenly, he was transmigrated into the cultivation world! Panic quickly strikes xian under the unfamiliar world he was "thrown" into. A few hours passed, he calmed himself down and surveyed his surroundings.

...

12 years passed and xian was far from the boy he was, when he was first transmigrated into this world. Xian came from a boy who was panick-stricken, to a man, who had established a somehow stable firm hold in the cultivation world after experiencing so many despairs. Xian who was now an outer disciple of the mount hua sect, was on a mission issued by the sect, when he was assasinated by four assasins, who was far stronger than he was. Having not accepted that he was killed just like that, he swears, "If i would just have one more chance... I would be far stronger and not be someone so low! I would be someone the world revered!! I would not be bullied and be the stronge--" just as he finished his last words... [Ding!!] [Congratulations host for triggering the supreme cultivation system!] [Error! Host seemed to be on the verge of death] [Activating ***********]. Xian who was on the verge of dying had no idea what just happened. "what the...?" Xian said, as he draw his last breath.

...

Xian was jolted awake, as he saw himself in a familiar room. [Ding!] [Host had been successfully transferred to blue planet!] [Warning! Blue planet will face the apocalypse in three days. Advice host to be ready.] Xian is confused from the information that had flooded his mind. Xian finds himself back on the Blue Planet, but with a newfound sense of purpose and determination after his experiences in the cultivation world. With the impending apocalypse looming, he knows he must use his second chance wisely.
