Rubik's Cube Prison

"There is a shortage in the prison, come here." Once when he went back to his hometown to sweep a grave, Lu Fan picked up a dark golden Rubik's Cube in a dilapidated temple. He was forcibly encased and assigned, and became the lowest jailer in the Heavenly Prison. While others collect demons and become gods, he watches the gate of the prison. Until Jiuweihu, Qiongqi, and Yaozhu were escorted in one by one... "Today's custody - a repeat offender from heaven, an ancient ferocious beast, Taotie." "I am the Master of Three and Five Du Gong Sutras, the Selected Scholar of Jiutian Golden Tower, and the Prison Guard of Tianlao——" "Prisoner signs for receipt!" Heaven is broken, the three realms are in chaos, and the three realms are all looking for the person guarding the last door.
