In 1943, Chu Weiguo fished out a talking metal monster while fishing at the bottom of Weishan Lake. It calls itself a mecha and says it has been waiting for 400,000 years to find someone who can pilot it. But Chu Weiguo had never even touched an electric light a few times. What's even more terrible is that the head of the Japanese military spy agency, Inoue Hiroshi, is tracking a mysterious signal, which comes from the core of the mecha. His wife and daughter were detained in the gendarmerie, and his brothers were trapped in enemy-occupied areas. Chu Weiguo repaired trucks for the Japanese army during the day, and wore a mecha to blow up arsenals at night. Stardust fuel is used less and less, and the circle around the well is getting tighter and tighter. When the mecha transformed for the last time, Chu Weiguo found that there was someone he knew in the cockpit.
