I Transmigrated As A Mecha: Unlimited Evolution

Transmigrated into Xingtian, a legendary but decrepit mecha, Yu Xiao faces a terrifying apocalypse. Worse, his fiery pilot, Bai Ying, is recklessly driving him to an early grave – and a scrap heap. As the last line of defense against monstrous Leviathans, Xingtian is on the verge of permanent shutdown. Just as humanity's fate hangs by a thread, and his own existence is threatened by dismantling, a game-changing 'Evolution System' awakens! Every monster slain fuels his path to infinite power, unlocking upgrades, new modules, and even the tantalizing possibility of becoming human again. But can he survive his own destructive pilot and an onslaught of horrors long enough for his first upgrades to arrive?
