Check-In to Become a God,清算 the Divine Ancestors

After Lu Xuantong is framed by his beloved Xiao Zixi and her lover Cui Hao, he loses his supreme bone and is cast into the Demon-Suppressing Tower. On the brink of death, he binds the Universal Check-In System, obtaining divine pills and techniques to slay demons and cultivate for twenty years inside the tower. Upon breaking out, he has already reached the realm of a land immortal, returning with the ancient phoenix Xia Ling'er to seek revenge and execute his enemies. Later ascending to the Heavenly Realm to find his family, he becomes entangled in inter-racial conflicts, unlocks a divine bloodline and inheritance, merges the dragon and phoenix primordial energies, and ultimately becomes the supreme ruler of the heavens to protect the safety of the three realms.
