In 2077 AD, a great cataclysm came. The ancient gods and beasts in the Classic of Mountains and Seas broke through the void, and the world became purgatory. The nine infants hold poison, the strong wind flaps their wings, the flesh and blood body trembles before the ancient tyranny, and the steel mecha becomes the last remaining flame of mankind. In this collapsed order, Lu Yuan, a defective experimental subject who was abandoned by the plutocrats, accidentally awakened the serial 001 mecha - Yinglong, which was covered with red rust in the ruins that had been abandoned for thousands of years. His pupils opened, electric current leaped among the galaxies, and the mechanical gears rubbed out a world-destroying war song. Lu Yuan wielded the miraculous blade and broke through the bones of all monsters, letting the ancient gods of the heavens hear clearly: Even if a mortal transforms into steel, he can still wield the authority to judge the gods. This is the last charge of civilization, and it is also a bloody elegy for mechas and gods.
