In the twenty-sixth year of the Republic of China, unknown secrets were hidden in the alleys of Beiping City. Shen Yanci was originally a mechanical student at Yenching University, but he accidentally picked up a mysterious chip from the interstellar world. The moment the chip was activated, the cold mecha blueprint spread out in his mind, and the roar of metal gears broke the silence of the old era.
Surrounded by foreign enemies and his country in turmoil, he used his desk as a battlefield and a welding gun as a sharp blade to forge China's first interstellar mecha in a dilapidated warehouse. When the giant steel body stood at the top of the city of Beiping, and when the light of the energy cannon tore through the sky, the sleeping Eastern Lion finally opened his eyes. This is a collision of technology and passion, and a legend about a scholar who uses a mecha to protect his family and country.
