My Realm Rises One Level Every Second, and the Myriad Worlds Are in Shambles

[Transmigration + Cultivation + Multiple Female Leads + System + Invincible + Old Fox] Qin Changqing transmigrated into the Leiyun Cultivation World and became the Qin family's good-for-nothing. His cultivation talent was poor, and after his legs were broken, he was thrown out of the family to fend for himself. Luckily, his keep-a-low-profile System showed up. “Congratulations, Host, on successfully transmigrating. You have obtained the Automatic AFK Level-Up System, which increases your cultivation by one level every second.” “Hey, Keep-a-Low-Profile System, how did I end up with a thousand levels of body refinement?” “It's over, I'm cooked! The System's default setting was one hundred million. I forgot to change it to ten!” “Holy crap!” Three years later... “Ding! Body refinement has reached the one-hundred-millionth level. Congratulations, Host, you have advanced to the first level of Qi Refining.” Haha! With millions of levels in Qi Refining, I can wipe out the heavens, the earth, and the air with one punch. A Foundation Establishment cultivator... all it takes is one slap to kill them. “Ding! Congratulations, Host, on defeating an enemy above your level. Reward: God-Slaying Sword Intent, capable of destroying immortals and gods.” “Ding! Congratulations, Host, on getting married. Reward: Chaos Body, plus the Chaos Yin-Yang Art.” “Ding! Moon Yao, the goddess, has been detected. You have received the goddess's blessing. Reward: one world-space.” “Damn, this System is so friendly. It keeps giving me invincible techniques. There's no way I can't be invincible! The Myriad Worlds are going to lose it.” Qin Changqing just leaves himself AFK and gains a level of cultivation every second. Who needs to cultivate? You've got to be kidding! Actually, fairies and goddesses are what I love most! Take note! My cultivation may be lower than yours, but you'd better not provoke me, or I'll blow you up with one punch. And so, a peerless prodigy appeared out of nowhere, traveling carefree through cultivation with beauties by his side. Becoming an immortal or a god was no dream. Immortality is the goal of me, Qin Changqing.
