A strong individual personally cultivated by Zhou Tian wanted to betray him. In such a situation, when outsiders faced Zhou Tian's church, they would naturally think at that time: A church that couldn't even retain the talents trained by Zhou Tian, no matter how great the opportunity within it, wasn't worth their allegiance.
Therefore, Zhou Tian absolutely could not let that situation occur. It was under these circumstances that Zhou Tian decided to carefully select the successor for a portion of his energy.
There were certainly many suitable candidates, but wanting Zhou Tian to be completely at ease was no easy task. At least, after Zhou Tian sensed many living beings within the castles, he still couldn't find someone he could truly trust 100%. So, when Zhou Tian didn't want to stay long in that world under those circumstances, since he didn't sense a suitable successor, he could only employ some tactics at that time.
