I, God! Going Down to Earth to Find Mahjong?

I, Li Huanren! In the first three thousand years, he realized enlightenment in the mortal world and ascended to immortality in the daytime; in the next three thousand years, he guarded the treasure in the heavenly palace and was ranked as Shaojian! I originally had a great path to immortality, but my immediate boss Yubao Zhenjun and his friends stole the Nine Heavens Treasure tiles refined by the Emperor of Heaven to play mahjong. The magic weapon went wild and fell into the mortal world. I was the one who was punished on my behalf to recover 144 mahjong tiles!
