Back then, Xie Dong had nothing inside his body except the energy provided by the zombie virus. Therefore, his body absorbed the energy of the lake water after being drained, and he woke up soon after.
If the vine plant hadn't removed the zombie virus from his body, and if the lake water hadn't changed his body condition, he surely wouldn't have become what he had—a zombie who looked like a human being.
Except for that bad-tempered vine plant, nobody knew about that; neither Lin Qiao, nor Xie Dong himself. Xie Dong didn't even remember how he became a zombie.
Junjun opened her mouth toward Lin Qiao, yet didn't utter any sound. However, Lin Qiao had already heard what she wanted to say. So, she wrote on the clipboard, 'I need to talk to it about that. But, to restore your bodies and voices, it will require energy. We can use energy nuclei of human beings, zombie nuclei, or those of mutant plants.'
