In just a short while, Gu Bei finished his arrangements and sent a few Heavenly Fate Realm experts to the smaller realms to hunt for ordinary demon spirits. It was a small task for them, of course. However, since Nie Li had personally entrusted this task to Gu Bei, everything would have to be very secretive. Therefore, Gu Bei only sent his most trusted aides.
In the span of a single day, Gu Bei’s men managed to gather more than twenty thousand demon spirits from one of the nearest small realms.
Nie Li received the first batch of demon spirits and returned to his room to begin refining them. There were quite a few among these twenty thousand that had Good or even Excellent growth rates.
