Others Have Superpowers, but I Cultivate Immortality, Laying Low Until the Great Ascension

【High martial arts + cultivation + System + keeping a low profile + invincible】 Secret realms descend, demons invade, and humanity awakens supernatural powers to fend off powerful enemies from beyond the world! Lu Xuan transmigrates to Planet Earth and becomes a lowly undercover agent embedded in an evil organization. At this critical moment, he awakens a Survival System. As long as he meets the requirements, he can earn survival points and open treasure chests. There’s just one thing: the System’s style is a tiny bit off. 【You were bitten by a corpse ghoul and survived. Survival points +10!】 【You escaped unharmed after being surrounded by more than ten demonic cultivators. Survival points +20!】 【You…】 Lu Xuan: This is supposed to be a high-martial Apocalypse, so why did I awaken a cultivation-world survival System? System, you’ve got the wrong guy, haven’t you? 【Opening treasure chest…】 【Congratulations! You obtained a Bone Spear!】 【Congratulations! You obtained a Five Poisons Pouch!】 【Congratulations! You obtained the Human Emperor’s Banner!】 Lu Xuan: …The System is working perfectly. From now on, I am the only immortal in the world!
