In fact, Wu Chengyue and Meng Yue had just arrived. Once they got here, they saw the familiar female zombie dip her claws into the snake blood and then put into her mouth. It wasn't a beautiful scene, but was definitely a little weird.
Both of them were quietly observing the zombie, which soon discovered them even though they had restrained their vibes as much as they could. Wu Chengyue was powerful, so once he restrained his vibe, almost no zombies and superpowered human beings who were weaker than him could sense his presence. Unlike him, Meng Yue used a special way to hide her vibe. She merged it with the vibes of the surrounding plants, as if she was hiding her own vibes among that of plants. Therefore, it was pretty difficult for anyone to sense her vibe now.
At that point, not even a level-six zombie or superpowered human being could sense Meng Yue's vibe easily.
