According to the plan before creation, there could be four situations after Qingtian's defeat:
Either take advantage of Su Xin's carelessness and bring Qingtian back with the seven-colored light.
Or if Qingtian is killed, they can retrieve his body and resurrect him.
Or if Qingtian is captured, they have the ability to communicate spiritually with Qingtian at any time and the confidence to revive him anytime, without worrying about Qingtian betraying the Divine Realm's secrets.
The worst is the fourth situation—
Qingtian is killed, and the body is hidden.
Originally, Qingtian's mind was always linked with the Mind Master, as long as he was still alive, no matter where Su Xin took him, they could sense Qingtian's exact location in real-time, and seize the opportunity to bring him back during Su Xin's lapse.
