[Real mecha + biological intelligence + devouring upgrades + unifying the universe + no harem] When the Tyrannic Empire was about to fall apart, Li Nuo, who had awakened his memory, resolutely joined the army in exchange for citizenship in order to give his sister a stable life. Unexpectedly, he became cannon fodder on the battlefield and accidentally obtained the biological intelligence Arad from another world. As a biological intelligence, Arad has unlimited possibilities for upgrading by devouring high-energy materials. If he fuses with mechas, he can become an infinitely upgradeable super biological mecha. If he fuses with Li Nuo, he can become the strongest human being. The two become partners. Along the way, they fight hard for survival and ideals, just because they believe that man can defeat nature!
