Early in the morning.
After a night of experimentation, Xu Qing looked at the three small bottles in front of him with satisfaction.
This was the ninth batch of little black bugs he had nurtured after a large number of experiments.
In reality, the word 'black' could no longer be used for this ninth batch. Their color was already translucent and their size was smaller than before. The difference was like the difference between an egg and a peanut.
Even in the past, the little black bugs were already invisible to the naked eye. Even with his perception, it was difficult for Xu Qing to sense them thoroughly. Now, they had become even more terrifying.
Even Xu Qing himself had to rely on the blood resonance to sense them, let alone others.
