During the War of Resistance Against Japan, son Gu Yi Nong arrived in Shanghai. He accidentally picked up the wrong suitcase and was intercepted and killed. It turned out that he was accidentally involved in the torrent of various forces fighting for the national treasure "Beijing Apeman Skull". They all tried their best to threaten and set up numerous traps on Gu Yi Nong, with the intention of using Gu Yinong and others to break the hiding place of the national treasure so they can win the national treasure and ask the Emperor of Japan for credit. At the critical moment, Gu Yi Nong stepped forward under the active guidance of progressive patriotic youth and the Shanghai underground party organization of the Chinese Communist Party, cracked the code, eradicated the national scum, and protected the national treasure from falling into the hands of the Japanese. Gu Yi Nong also transformed from a stunned dude into a warrior. (Source: Baidu)
