Originally, besides Ruan Ruan, Su Yuan indeed had no intention of contracting any other Guardian Beasts.
The reason for deciding to contract Mo Fei as a Guardian Beast now is that Mo Fei's character and potential are quite remarkable, and he already possesses the strength to stand on his own.
In solo combat, if nothing unexpected happens, Ruan Ruan is no match for him.
Secondly, the emergence of the Grey Realm is a great opportunity to plunder Star Cores.
Contracting Mo Fei as a Guardian Beast would allow him, like Ruan Ruan, to hunt Star Dust for Su Yuan.
Mo Fei has a nature that can endure hardships and a passion for combat, making this arrangement most fitting.
After some contemplation in recent days, Su Yuan finally made this decision.
Since there was to be a Guardian Beast Contract, the previous servant contract naturally became obsolete.
Tearing up the servant contract not only gives Mo Fei another chance to choose, but also serves as a small test for him.
