It was for several reasons that Yan Fei decided to build the Super Nuclear Power Station underground. After hearing Yan Fei's plans, Yang Qi didn't quite understand his approach, since constructing a massive Super Nuclear Power Station below ground was very troublesome. It would not only significantly increase the construction workload but also be incredibly dangerous.
Nevertheless, at Yan Fei's insistence, Yang Qi still modified the previous design drawings of the Super Nuclear Power Station to make it more suitable for underground construction. This modification wasn't substantial, involving only changes to the placement of specific equipment, the routing of the transmission cables, and considerations for adding nuclear fuel. Consequently, the revisions were completed quickly and confirmed through the Technology Analysis System.
