Let's set aside the Flower God for the moment. Inside the Adisa, Jia Yan was continuously devouring and breaking through, yet found himself unable to digest the Stellar-level Ghost's Blood.
One must understand that this was unprecedented; the body of an Evolutionary Creature had always given Jia Yan the confidence to devour any substance.
But now, he encountered some obstruction while devouring this Stellar-level Ghost's Blood.
"This is normal. After all, even though Stellar-level Space Ghosts are somewhat weaker than typical Stellar-level strong ones, they are still genuinely Stellar in rank. It's only natural that their Essence Blood is difficult to absorb."
