Spy Under Sky Chapter 156

Gavin Lin took the materials from Liu Mancang and started looking through them.

According to Zhang Shifeng's confession, he went to Japan's Third High School to study in the preparatory course in the 19th year of the Republic of China, that is, in 1930.

In 1931, with the occurrence of the September 18th Incident, the Japanese Ministry of Foreign Affairs began to become nervous about the movements of Chinese students studying in Japan, and monitored them through various means, including their convening of conferences, petitions to the embassy,   the organization of the Chinese Students Association in Japan and its charter, the return movement of students studying in Japan, etc., in order to fully grasp the movements of Chinese students studying in Japan after the September 18th Incident, and to look for suitable targets among them to act as moles for the Ministry of Foreign Affairs' intelligence organization.

At this time, Zhang Shifeng, out of jealousy, accidentally killed Tan Zushun, the son of Tan Qingguang, the leader of the Green Gang of Hangzhou, who was also studying at the Third High School.

The Ministry of Foreign Affairs spies approached Zhang Shifeng and forced him to act as a mole in the Ministry of Foreign Affairs intelligence organization to monitor Chinese students studying in the Kansai region of Japan. Otherwise, they would tell Tan Qingguang about his killing of Tan Zushun and send him back to China. Zhang Shifeng, who was afraid of death, became a mole in the Ministry of Foreign Affairs intelligence organization.
