You couldn't blame Kou Jiao for being surprised. Not only did Wang Teng detoxify his Thousand Spider Poison Powder, but he also took a short time.
He kept urging Wang Teng but it was just a psychological tactic. He never thought that Wang Teng would be able to detoxify the poison in such a short time.
The Thousand Spider Poison Powder was at the grandmaster sixth-level. It was extremely complicated and couldn't be solved easily.
He wasn't the only one. Even the other doctors didn't come and try to cure this grandmaster sixth-level poison.
The reason why they did this was because the medical talents didn't think that this poison could be cured in a short time. Hence, they might as well find other low-rank poisons first.
The criteria for the doctor competition was based on the number of the poisons they treated and the quality of the poisons.
They wanted to get rid of the low-rank poisons before others.
