Zixiao binds to a system. He thinks he's a mortal, but his writing becomes heavenly decrees, and a stone he throws can kill a Grand Celestial Immortal. Aella becomes his servant. Grand Celestial Immortal smashed! Lord Aethel destroyed! Primordial Lord of Heaven kneels, Patriarch Hongjun cries for help. Zixiao says: I'm really just a mortal, can you all please stop kneeling?
