Xi'an and Bai Shu conducted two transactions in total:
For the first time, the god Xi'an took a fancy to the talents of Shen Qi, a powerful official in the mortal world, and asked Heaven to help Shen Qi plant his spiritual roots. After Shen Qi cultivated, he had to help Heaven to fulfill the "rules" responsibility.
For the second time, the god Bai Shu made a deal with the mortal Ye Hua'an. Ye Hua'an reunited the creatures of the desolate land caused by the war between heaven and demons thousands of years ago. Bai Shu helped Ye Huaan ascend to immortality and transform into a god.
Ps: Ye Hua'an is the reincarnation of Xi'an. Shen Qi became an immortal and changed her name to Bai Shu
Purpose: uphold justice
