Ghost Project Angie's identity was discovered in episode 20.

Angie saw this brand-new Wu Siyuan at first sight when she woke up from her injury, and she felt very close to this person who used to be a student of Xie Zhiyuan and An Feiyong. ? Daba, a China native who Secretary Zheng and his organization have been looking for for a long time, witnessed the evidence of destruction when 73 1 troops were defeated. His face was disfigured at that time.

Episode 20:

Zhang Hanyu told Zhu Keran that she was a "bamboo". Zhu Keran verbally obeyed Nuo Nuo's promise and all orders, but she had doubts. When Zhang Hanyu let Zhou Xue go, Zhu Keran tied Zhou Xue back immediately. ? Old "K" asked Xie Zhiyuan to exchange the experimental report of cracking "SS3" with the living An Feiyong, and at the same time, he had to personally meet the "Red Heart Emperor" from Taiwan Province.

Fujita finished SS3 alone, while Xie Zhiyuan and his wife An Feiyong were determined to decode SS3. One made "Mao" and the other made "Shield". At that time, in order to stop Xie Zhiyuan's research, Fujita forced An Feiyong to commit suicide by jumping into the river, but he did not get the key experimental data from An Feiyong.

This is also the reason why Xie Zhiyuan had to identify Kang Xiuying. He thinks that Kang Xiuying now is Hirono Fujita before Ann Fei Yong. Xie Zhiyuan's face is full of vicissitudes, and there is no shadow of Fei Yong. ? If one plan fails, try another; Kill two birds with one stone.
