After a brief moment of contemplation, Yu Liang overcame his inner resistance and retrieved the Sentinel Beast Matron from the universe.
A corpse is just a corpse, a resource to be utilized.
Moreover, these were the corpses of Ghost Men, no longer ordinary people.
Next, the Sentinel Beast Matron began to build a nest on site to lay eggs. Since the whistle beasts she produced needed to parasitize corpses to complete their growth, and each whistle beast had a short lifespan but required a significant amount of the matron's energy, Yu Liang decided to consider producing and utilizing whistle beasts only after entering the instance.
After all, the juvenile and growth periods of the whistle beasts were very brief, and given sufficient energy, they could fully mature in just a few hours.
Once the ordinary whistle beasts were raised, the matron would lay eggs again, and the new scorpion-shaped parasitic creatures would infest the ordinary whistle beasts, thus obtaining advanced guards.
