In the Bamo darkroom, the Japanese second lieutenant pressed the red-hot iron to Lin Chongxiao's chest. He didn't hide. The soldering iron smashed the shirt pocket, revealing half a yellowed drawing - "Bulletproof Protective Equipment Structural Drawing". The second lieutenant's pupils shrank suddenly and he let go of his hand. The next day, the British intelligence officer delivered whiskey, the US military adviser handed over the checkbook, and the puppet envoy Wang carried the gold bars. Everyone wants to buy this paper. Lin Chongxiao knelt down to receive the gold, then turned around and changed three key parameters on the drawing: one for the Japanese army, the steel plate would crack; one for the British army, the size was two inches off; and the real one was sewn into the belt buckle of a brother who died in battle. The Japanese female spy used her body to test, and he smiled and chewed up the poison capsule before spitting it out; the military lurking team put a gun to the back of his head, and he handed over a distribution map of Japanese firepower points with his backhand - drawn with a pencil on the back of a bulletproof test record sheet that had been burnt three times by cigarette butts. Until that night, special envoys from the four countries gathered in the Bhamo warehouse, each holding an "exclusive formula" to detonate explosives. The fire licked the night sky, and the cement pillars exploded into pieces. A man walked out of the smoke, and bulletproof steel pieces jingled out of his flesh. Lin Chongxiao tore off the burnt fake face, put on his seventh disguise, and reached out to touch the real drawings in his arms. The next second, he knocked on the door of the chieftain's armed village - "I'll sell you a kind of bamboo armor that bullets can't penetrate. Just tell me where the secret barracks of the Japs are in Savage Mountain."
