The skill of giving people cowpox was incredibly magical.
Anyone who encountered an old flower vendor in their dreams, and was unable to resist the temptation to buy the different beautiful fresh flowers in her hands, would come down with smallpox.
The larger the flower, the more severe the illness became.
If one were to exchange the purchased fresh flowers with someone else in a dream, it was tantamount to swapping the pox onto oneself in reality.
There was no doubt that she was a strategic-level bio-weapon!
If left to her own devices, not only the battlefield of Bijia Lake but also the nearby cities would suffer.
However, she was completely eradicated from the root by the "cowpox" vaccine developed by Sage Wu's modern medicine, and smallpox no longer existed in the world...
"Damn it! There's a conspiracy!"
"Another one, how sinister."
"There must be some trickery involved here!"
