Xu Qing ignored Yanyan. His research into the black beetles had still not yielded the results he sought. The way they ate the target from the outside in was definitely not what he wanted.

I think I need to pick between two possible directions of research. One is big beetles, and the other is small ones....

After some thought, he picked the latter.

That would be the key to killing silently. After making some adjustments to his methods, he continued with his work. He felt good about the decision. It was like he was a scholar doing research, constantly adjusting his methods as he sought the answer to the question.

In addition to zombie poison, he added other types of poisons he had created over the past two years. Although those poisons seemed ordinary in nature, when the beetles ate them, they gave them a powerful ability to resist poisons.

If this works, then I’m going to have created a truly unique new kind of poison. A living poison.

Compared with all the other poisons he had invented already, this one definitely stacked up on top.

Of course, as time passed, Xu Qing went through spirit stones...
