178 Life Fire, Mystic Brilliance, Illuminating the Heavenly Palace

That night, Xu Qing gained a lot.

He had grabbed a total of about 700 ammonites.

As he looked at the ammonites sealed in ice in his storage bag, six to seven poison recipes that matched this item appeared in Xu Qing's mind. The might of each of them was extraordinary.

"There are also my Ghost Desires. If I combine them with the ammonites, and add some medicinal herbs transformed from the two extremes of yin and yang… Perhaps I can make poison powder that will cause even Foundation Building cultivators to die?"

Xu Qing pondered for a moment and felt that his thoughts were still a little optimistic. He recalled the battle with the Diamond Sect's ancestor. The other party's resistance to poison was extremely strong. Presumably, the latter wasn't an exception.
