On the train, the important staff of the Japanese military aircraft were heavily protected. Song Zhuowu and his comrades disguised themselves and cooperated, and finally obtained the meeting minutes and took photos.At night, at Lao Qian's residence, the film secretly taken from the train was developed, and the meeting records were shocking.
During the meeting, the Kwantung Army Chief of Staff asked all departments to step up preparations for the Tonghua Defense Plan to deal with a sudden Soviet attack. At the same time, he said that it would be okay even if the Kwantung Army did not have reinforcements from the Pacific, because the secret weapon developed was a ceramic bomb.It can be put into use in a few days.“Tonghua Defense Plan” and “Ceramic Bomb”, these are two unheard of but significant pieces of information.
This may be the last desperate struggle of the Japanese army.The Harbin underground party must find out the truth about “Tonghua Defense Plan” and “Ceramic Bomb”.Lao Qian attracted the attention of the Japanese by deliberately releasing the news of “ceramic bomb” in the underground intelligence trading market.
Pan Yue inspected the train and realized that the document may have been leaked.Guan Xue began to plan how to deal with Song Zhuowen and Song Zhuowu before going to Japan.
