Jian Wushuang had come into contact with poison before.
There were many experts in the Eternal Chaotic World who excelled in using poison. There were many who had also excelled in using poison back in the ancient past.
However, out of all of the poison Jian Wushuang knew, none was as terrifying as what he was experiencing!
This type of poison could have killed any Divine Demons even back in the Absolute Beginning Divine World without the Restrictions of Heaven and Earth easily, much less a mere chaotic realm expert like Jian Wushuang.
However, Jian Wushuang understood why Leng Ruxue was able to use such a terrifying poison.
After all, Leng Ruxue had an unique constitution. Back in the Green Fire World when Leng Rushuang had controlled her own body, she had possessed the Icy Bone Poison which was a nightmare for any expert in the Green Fire World. Now that Leng Ruxue was much more powerful than before, the poison she could use was much more terrifying.
