The New Legend of the Transcendent, Invincible, Unfettered Honghuang

The protagonist, Lu Heng, transmigrates into the Primordial World and awakens a Carefree System. Killing monsters gives no experience, cultivation has no bottlenecks, karma cannot touch him, and tribulations cannot harm him. He is absolutely invincible in the most literal sense. But the System has a first hidden rule: he must not form a bond with any living being. Otherwise, the person he bonds with will suffer the backlash of Heaven’s will and be utterly destroyed in body and spirit. To be carefree is to be eternally alone.
