No matter how you look at it, Jiumo Law King is an excellent candidate for a cooperative team. You really couldn't find a better one even if you were searching with a lantern.
In terms of strength, he ranks twenty-first on the Heavenly Ranking. Only a few people could be ahead of him in The Other Shore, making it difficult to gather them. Among them, a few demon race powerhouse needs to be removed.
Considering character, Jiumo Law King and Ye Rong have cooperated several times, and have always been in harmony. No conflicts have ever arisen, and he can be considered trustworthy.
Moreover, as a disciple of the Buddhist Tantra Sect, Jiumo Law King's demand for equipment and Daoist books differs significantly from that of Ye Rong, a Daoist disciple. This means their cooperation would be more complementary.
The only regret is that Jiumo Law King seems uninterested in entering the inland area, preferring to stay on the Tibetan Plateau.
