Mecha Girl Chronicles: The School Beauty's Modification Request

Li Qiankun is reborn into the world of mecha girls, but with only F-rank combat aptitude, he is betrayed by mecha girls and his parents' inheritance is about to be seized by relatives. Just then, the "God-Tier Modification System" unexpectedly activates. It grants him the ability to modify any mecha girl into SSS-rank or even greater combat power. Li Qiankun rescues Xia Jin, a dying E-rank scrap-iron mecha girl, and modifies her into an SSS-rank force. He then enters the Mecha Girl Grand Prix to reclaim the inheritance that was nearly taken from him. But along the way, he discovers the conspiracy of the Machine God Cult operating in the shadows. Li Qiankun joins forces with Xia Jin, Xing Lan, and others to expose the truth that the cult has infiltrated the upper echelons and to stop their evil plan. With the power of the God-Tier Modification System, Li Qiankun modifies mecha girls one after another, building a mecha girl army. In the end, he annihilates the Machine God Cult's headquarters in a decisive desert battle and saves the world.
