Du Jiangbo's plan was undoubtedly well-thought-out. This way, he could leverage Gu Sheng's hand to eliminate the Black Sand Gang's martial artist, and then conveniently kill this unknown nighttime assailant himself.
However, there was one thing he miscalculated.
That was Gu Sheng's strength.
The reason Gu Sheng used knockout smoke wasn't that he couldn't handle the three men himself, but rather to ensure greater reliability and minimize commotion. With his current level as an Iron-Skin Martial Artist and his Perfect Realm mastery of the Iron Stone Fist, dealing with two opponents on the same level was as easy as child's play.
Moreover.
Given Gu Sheng's personality, even with the use of knockout smoke, he would never leave himself recklessly exposed to any flaw. While the smoke was useful, it wasn't without countermeasures.
Gu Sheng never places all his eggs in one basket.
