With a Health-Lock Cheat, I Can't Die, So I Have No Choice but to Become Invincible

[Invincible Power Fantasy] [Pick a Fight and See What Happens] [Driven to Grow Stronger] [Lighthearted Comedy] Gu Beichen accidentally transmigrated to a fantasy world. With such poor aptitude, he was utterly insignificant in his sect. He thought he'd spend his whole life stuck at the Qi Refining stage, but one day, he got a System that made him stronger every time he courted death. Complete the corresponding death-seeking missions, and he'd receive all kinds of rewards, including cultivation, supreme techniques, and top-tier magical treasures! Best of all, the System came with a health-lock cheat that let him ignore all attacks while it was active. From then on, Gu Beichen began courting death like crazy, picking fights with the heavens, the earth, and everything in between. As long as he didn't die, he'd keep pushing his luck! Star Lodge Immortal Venerable: "Gu Beichen, you bastard! Why was my wife calling your name in the middle of the night?!" Blood Clan Progenitor: "Damn it, which one of us is supposed to be immortal? Why can't this guy be killed?! He's driving me insane!" Empress Yaoguang: "No one in the entire cultivation world can match Gu Beichen when it comes to courting death!" Years later, Gu Beichen, whose cultivation surpassed that of the Immortal Emperor, looked down upon all living beings and sighed. "I really did become invincible by courting death like crazy."
