Beasts of affection could be cultivated again, and using these beasts in exchange for rapidly enhancing the strength of his subordinates was not a disadvantage for Su Han.
Moreover, to some extent, it could save time for Gan Xinglei and the others to continue cultivating a second Angel Envoy.
Currently, there were no second-grade monsters imprisoned in the camp, so contracting a second-grade monster would require further searching, or contracting a First Order Upper Grade and then continuing to cultivate it.
Although it might be because of the Book of Blood Spirit, the second Angel Envoy, even if only a First Order Upper Grade, did not absorb Spiritual Energy as slowly as the first one in reaching its racial limits.
They could reach their racial limits faster under sufficient resources, or even directly break through to Second Order if their racial limit was high.
