The seventh episode Qiu Dekao disguised as a doctor of February Red.

February Red wanted to help Zhang Qishan, but she didn't want to come forward, so she wrote down her ancestors' information about the mine in a letter, and then sent four dried tangerines to secretly deliver the letter to Zhang Qishan's home. After receiving the letter, Chenpi did not send it to Zhang Qishan immediately, but made a copy in advance and took it to Yoshiko Tanaka. Chenpi did not immediately give a copy of this letter to Ryoko Tanaka, but asked to meet the real buyer. Ryoko Tanaka promised to take Chenpi to Changsha Chamber of Commerce in the United States and let him wait in the lobby. I didn't expect an assassin to ambush in this class, intending to plot against dried tangerine peel and take the letter directly. The magical power of Chenpi made the enemy into a bitter battle. At this time, Qiu Dekao appeared and ended the fight. Qiu Dekao seems to be the person who wants information. He said that if Chenpi gave him the letter, he would help the girl heal.

After Chenpi and Qiu Dekao reached an agreement, they took the original letter to Zhang Qishan House. Zhang Qishan and Qi Tiezui read the letter, and the font in the letter showed signs of deliberate change, but it was hard to hide the fact that the letter was written in February Red. After receiving the information written in the letter, Zhang Qishan decided to go again, but before going, he asked Qi Tiezui to know some local conditions near the mining area.

Lu Jianxun, the agent, was recently transferred to Changsha to assist Zhang Qishan. Zhang Qishan is wary of Lu Jianxun. He thinks this man is anything but simple. He may be different this time.

Qiu Dekao pretended to be a doctor and followed Chenpi to the Red Chamber in February to treat the girl. Jude Kao used morphine to temporarily relieve the girl's pain and gained the trust of the girl and Chenpi.

Qi Tiezui, disguised as a fortune teller, came to a town near the mine to get information from the local people. He found a crazy beggar acting strangely from the villagers' mouth, thinking that the beggar might know something, and found the crazy beggar according to the direction guided by the villagers. The crazy beggar kept pulling out his hair, still mumbling that it would eat him. Qi Tiezui learned from a beggar that ten months ago, when he went to the back hill, he met something terrible like hair, which made him very scared. Qi Tiezui shaved the beggar's head, and after comforting him, the beggar was finally less afraid. Qi Tiezui also learned from other villagers that recently several Japanese people came to the village and sneaked around the mine. Qi Tiezui gradually saw what was in the mine.
