After transmigrating into a chaotic fantasy world, the young Li Chang'an awakens the Ultimate Immortality System. Whenever he suffers fatal damage, he instantly revives at full health, with all attributes critically boosted and doubled! To ascend to immortality as soon as possible, he embarks on a crazed quest to get himself killed: slaughtering the Black Wind Stronghold and charging straight into executioners' blades, openly teasing the cold and domineering female Demon Venerable Yin Jiuge, and forcibly taking deadly ultimate techniques head-on for powerful figures of both righteous and evil factions. Unexpectedly, the more he seeks death, the more his physical defenses become utterly defiant of heaven, driving his enemies to despair as their attempts to kill him repeatedly fail. Faced with this ultimate monster who simply cannot be killed, the stunning female Demon Venerable's Dao heart completely collapses, and immortals and demons throughout the heavens lose all hope. 'Please, stop deliberately getting in our way! If we hit you again, you'll really ascend to immortality on the spot!'
