After Qi-Yi had grouped all the Sacred Sects’ disciples and started their journey, it took them about half an hour to reach the secret land gate. Along the way, they did not encounter disciples from Devil Sects and Demon Sects ambushing them at all because all of them had become corpses. Qi-Yi's group could guess who did it because the wounds on those bodies were the same as those of previous Devil Sect disciples.
“Senior Disciple Yi-Lin, this must be the action of Comrade Zheng-Fu!”
"Yes! It must be his work. He definitely wants to clear a path for us!”
“He's such a nice guy. Sigh! How many men will be like him?”
A female disciple, one of Yi-Lin's group, spoke up. They knew for sure that those wounds were caused by Zheng-Fu's flying daggers. And from what they observed, the disciples of both these Devil Sects and Demon Sects were all dead without even realizing it. It was therefore highly possible that Zheng-Fu did all of this.
