Xia Xin, who transmigrated into the cultivation world, mistakenly entered ancient ruins for trials and chanced upon an exquisite woman. Day and night together, affection quietly blossomed, and the two shared intimate relations, secretly binding as husband and wife. Who would have thought that stepping out of the ruins, the woman's demonic identity would be exposed, having spent years traveling alongside demonic fiends. Implicated, Xia Xin was severely punished by his sect and imprisoned at the Cliff of Repentance to reflect. At his lowest ebb, the check-in system suddenly awakened! Checking in daily, he harvested the supreme primordial sword body and heaven-defying realm charts, breaking through cultivation tier by tier, reaching the world's supreme realm. Achieving success and emerging from seclusion, Xia Xin fears no barriers between righteousness and evil, resolutely seeking back his wife, grandly making up for their wedding, and the husband and wife cherishing and guarding each other, soon giving birth to a son.
