Yuzhou was originally a peaceful place, but since that day, a shadow has fallen over Yuzhou. The water in the well cannot be drunk! The reason is very simple, it has been poisoned. But there is no basis for the poison. It can only be seen from the blue color. It was done by Lian Qinggong, the peerless poison sect in the martial arts world, and it was just a test of poison. The only thing, everyone knew, Lian Qing's poison was never spread to the outside world! So, why did Yu become a test drug? Is Lian Qing's original intention just like this?
Zhu Ling, who also bore the hatred of her parents, embarked on the path of no return in drug investigation.
It is clear that Lian Qing is difficult to deal with, but is Lian Qing really their enemy to them? Or, they should not have embarked on this path at all and should not know more about it? Because this path can make them fall like butterflies, and make Bingruo, an eighteen-year-old girl, endure everything that is simply unbearable!
Sometimes, you shouldn't know more and let everything be buried in a piece of yellow sand...
