The virus was developed by Shuyin herself. Although Lucas saved Zishan's life, he couldn't crack it, so Zishan's body had some residual effects.
Lucas had been developing this new and powerful virus for a long time, but he had not succeeded.
So he anxiously asked Shuyin for it.
This virus was too deadly, and Shuyin didn't want to give it to a lunatic like Lucas.
She took a piece of tissue from the bedside table and wiped the blood on the knife unhurriedly. She said coldly,""There's nothing else! If you want to cultivate it yourself, aren't you the best at cultivating viruses? You're asking a little girl like me for it, do you still have any shame?"
Lucas was already used to Shuyin's scolding. Besides, he felt that he was a shameless person to begin with, so he didn't feel embarrassed at all when he asked Shuyin for the virus.
