Yan Fei, upon acting, constructed a real Nuclear Fusion Power Plant, achieving a significant breakthrough in the History of Human Technology. However, this breakthrough was limited within the Dreamland Cave World. Once outside of the Dreamland Cave World, the critical components of the Nuclear Fusion Power Plant would collapse due to a loss of Energy support. Even so, the achievement Yan Fei had obtained was still a rare breakthrough in the History of Human Technology.
With the physical Nuclear Fusion Power Plant created by Yan Fei, Yang Qi immediately conducted close observations of the plant's operational process and collected operating data in real time, mastering all the top-secret Intelligence related to the Nuclear Fusion Power Plant. With this top-secret Intelligence, even if Yang Qi could not replicate the same Nuclear Fusion Power Plant in the outside World, he could still make some modifications to produce a weakened version of the Nuclear Fusion Power Plant.
