Sha Chen had already reached an agreement with the Dragon Kings of the Four Seas. They would bring their avatars back to the Dragon Palace to nurture the talented younger generation, and he thereby essentially established a formal mentor-student relationship with the Dragon Clan.
In addition to this, the Dragon Kings of the Four Seas also had to hand over the entire treasury of the Dragon Clan to Sha Chen. Initially, they only needed to contribute 80% of their wealth. However, the Dragon Clan's treasury had already been mostly emptied to provide for the cultivation of their talented younger generation. Thus, this time, Sha Chen wanted to empty the entire Dragon Clan treasury.
