Zheng Tianhe was certainly not pleased! He had long known about the Wood Element Superpower Users' ability to heal wounds, but what he cared more about was Fang Yuxin's Wood Element Superpower! He suspected that she was different from other Wood Element Superpower Users, possibly possessing a Mutated Wood Element Superpower. Thus, he particularly hoped that Fang Yuxin would cooperate with his investigation, ideally by voluntarily "sacrificing" herself to help him complete various experiments, rather than focusing on her ability to heal wounds!
However, he couldn't say that out loud. Qiu Yiming and Zhou Yan had significant reputations in the military, and even if he wasn't afraid of these two men, he had to consider the negative implications their discontent could bring. He knew very well that the military needed people right now and offending the superpower users could lead to an unfavorable outcome.
