Master Wu Dahai's appraisal ability was quite mysterious as it actually allowed him to understand the components of the materials he was appraising. However, because of this appraisal method, he would also lack some details that Shane and the other Foreign Survivors could see from the system description, such as the full description of their effects.
As soon as he touched the bottle, the Master Alchemist immediately realized that the one in his hands wasn't just some drug that could bestow powers to its consumer, but it also used Zombie Blood, which he had never considered before!
After all, Zombie Blood was extremely toxic. They are contaminated, and there would be a considerable chance of becoming Zombies once consumed if they didn't die.
Such an ingredient was just too risky to use!
