Zhu Yingjia used his final authority before retiring to approve Lin Kanshan's return to the mainland.Chen Yuanyuan was very angry after taking over the job. He classified Lin Kanshan as a highly sensitive person and ordered that he be arrested immediately as soon as he returned to Taipei.

When the hotel door opened, Jin Lina saw Jinlan, whom she hadn't seen for a long time, and thought she was only coming back to stay for a few days.Jinlan told her that she would not leave again this time and that the two of them could get along as before.After Jin Lina heard this, the grievances she had accumulated for a long time suddenly came up and she couldn't help crying.

After Lin Kanshan returned to the mainland, he received guests attending the cultural and trade forum.Li Qing in the delegation had another mission. He ventured to Mazu Park to meet with retired Wu Shenglai and handed over the list of four potential personnel, and also brought news about the possible leakage of Huanyu No. 10“ combustion accelerator technology.

At the venue, Lin Kanshan, Ma Qi and He Chunxiao met, joking on the surface but leaving room behind their words.Lin Kanshan excused himself to go to the bathroom, and Ma Qi followed him in, sending a message to the Taiwanese side: He had to go back as soon as the forum was over. If he didn't return within the time limit, someone would come looking for him.He Chunxiao then came in and the conversation was interrupted.

Lin Kanshan left the meeting and called Zhu Yingjia for confirmation.He suspected that Ma Qi had already contacted Chen Leyuan, and he would be locked up as soon as he returned.After Zhu Yingjia hung up the phone, he reminded Zheng Guiping that he could meet in person next time Ma Qiuchi came to Taipei.

At night, Lin Kanshan returned to his empty room, looked out the window and called his father.He had a vague premonition of his own ending and wanted to say one more precious word, but Lin Zude had already hung up.Lin Kanshan sat on the sofa and cried. He Chunxiao and Jinlan who were monitoring the scene also felt mixed emotions.Jin Lina took the initiative to come to him at this time, and the two rarely talked about their innermost feelings on the balcony.Jin Lina said that if she had not met him, she might have died long ago; Lin Kanshan replied that the really difficult thing is to continue to live.

At the morning meeting of the Second Division the next day, He Chunxiao linked Lin Kanshan's land acquisition to the expansion of the military airport and proposed arresting people immediately if any abnormalities were discovered.Wu Jiali also brought back a tip-off that the Military Intelligence Bureau was making every effort to obtain the Huanyu No. 10 burner technology, and the leakage channel must be discovered as soon as possible.

Ma Qi went to see Yang Shiwen alone and flew to Taipei through his arrangement.Zheng Guiping asked him about ”Huanyu No. 10% and proposed a high reward, but Ma Qi did not agree easily.On the other side, He Chunxiao led people into Yang Shiwen's room and confirmed that Ma Qi had left the mainland.

During morning tea the next day, Chen Leyuan appeared in front of Ma Qi and bluntly expressed his hope for cooperation and requested intelligence from multiple countries and regions.Ma Qi looked at his domineering look and still did not express his position on the spot.After returning to the mainland, he noticed someone was following him as soon as he got into the taxi, so he borrowed the help of the driver to call the hotel and inquire about Yang Shiwen's whereabouts.
