The entire process ran through Zheng Yi's mind, and he quickly thought of a possibility.
The Flesh Nest had been set up using a large amount of zombie flesh and blood, which was entirely different from the flesh and blood used in the Da Yi Immortal Domain.
And during the incubation process, perhaps it was because the zombie flesh and blood had infected the blood bats' bloodline that this situation had arisen.
"The Blood Bat Cubs have acquired zombie bloodlines and directly become half-zombies, which is why they attack and devour one another?!"
Perhaps that was the most correct answer.
"These Blood Bat Cubs have also inherited the zombies' rapid growth trait. They can grow simply by devouring flesh and blood. I really want to see what happens next!"
Zheng Yi's interest had been piqued, and he very much wanted to continue his scientific research.
One had to know that in the Da Yi Immortal Domain, the spread of the Blood Bat Palace Cultivation Secret Method had once sparked several waves of fervor.
Blood bats had always relied on sheer numbers, using an overwhelming swarm to slaughter their enemies and seize the final victory.
Yet this incubation seemed to have produced some sort of change. It was like raising venomous insects in a jar—an entire batch of more than a hundred Blood Bat Cubs devoured one another, until only three to five blood bats remained.
Zheng Yi was also very curious about what they would ultimately become.
"Right. After blood bats hatch, they need to devour Spirit Stones to strengthen their bloodlines. That is recorded in the secret technique."
Zheng Yi hesitated. To be honest, he did not want to use Spirit Stones to raise blood bats.
It was not because he begrudged the Spirit Stones in his possession. He
