After sending Lin Xin and Lin Xuan off, Lin Huang sat alone in the courtyard and checked on the status of his Monster Cards.
It had been close to five months since he had released his imperial monsters to obtain their own cultivation resources. Since then, he had practically never reviewed Bai and the others' cultivation progress.
Now that he finally had time, he began to check through the cards one by one.
The first Monster Card he saw was Kylie's. She was already at Pure Spirit rank-6 and was, without a doubt, the strongest powerhouse among all the imperial monsters.
Four months ago or so, Kylie had already elevated to heavenly god-level. Now, in just these four short months, her combat strength had gone up to sixth-rank heavenly god-level.
This sort of advancement speed could practically be considered terrifying.
