The Scum Is Awesome 

Everyone fell silent. They already expected to hear this, but still, it is different hearing it from You Rou herself. They didn't expect though that You Rou would tell them the story behind her training in martial arts like this, as she had seen their shock from her showing her skills to them. Not that they were disappointed of her. On the contrary, they were awed by her instead. And Cheng Sheng behind her is even more awesome. For he created two beneficial talismans just to find a solution for You Rou to learn martial arts. 

Cheng Sheng truly is a genius. No doubt about that. No wonder he can lead everyone in this battle against the foreign enemies, and no one complained of him on his back, much less outrightly objecting to his plans. Though, another reason why he became the one in lead for this battle is due to his reflexive thinking and novel ideas, as well as his knowledge of the foreign enemies, which also stemmed from his mysterious acquaintance.
