In the plot, everyone knows that Sun was lynched because he pretended to be lynched. From this, we can infer that since Sun can pretend to be the changer, he must know the existence of the changer, and his memory cannot be erased, otherwise the Mingde General Administration will not drag him to cut his brain. As a person, why can't the memory be erased? This is a doubtful point of view.
When Hao Yun was in the General Administration of Mingde, Li Zhengzheng, Wu Aiai and others introduced the golden monkey, an endangered species in China, to discuss what kind of project to allocate to Hao Yun. There are only three golden monkeys. Two of them are lovers. The third one is missing. And Guo Jingfei happens to play this monkey, so is he the missing golden monkey? This is also a doubt. If Sun is really a golden monkey, it is normal for the passive management department to mistake him for an adult because of his rarity and unknown whereabouts.
Before entering the third mystery, let's infer Hao Yun's real identity from the events in the last two episodes. It seems that Hao Yun has been recognized as a human since he came to the General Logistics Department of Mingde, so is he really a human being? The answer is definitely no, you know, when Hao Yun first entered the Mingde General Administration, he was only detected by ordinary camera equipment and found to be a person. Later, after the mid-term adjustment in Li Zhengzheng, Mingde General Administration decided to use the latest international instruments to test Hao Yun's identity again.
When accepting the latest instrument testing, Mingde General Administration said a word to the agent: If it weren't for the order of President Wang, an agent like this would not be qualified to use such high-end instruments. Some converters can't be detected by ordinary camera equipment, and they need high-end camera equipment to be detected. After Hao Yun entered the machine, I only heard that Hao Yun was transformed. As for the program, the instrument did not detect it and exploded directly.
Attention! Judging from their expressions, they don't know what happened at the end of the explosion. So why did the instrument explode when testing Haoyun compendium of materia medica? Hao Yun's program is probably not a normal animal, but an ancient mythical animal, so the current instrument can't carry so much energy and can only explode. If Haoyun is a beast in ancient mythology, this further confirms the fact that he is the son of Suzaku.
According to the suspicion in Mingde General Administration, Sun's appearance is a very obvious third doubt. The reason why Sun Qinling was regarded as an impostor by the General Administration of Mingde was because he only accepted the photo test of the General Administration of Mingde and did not accept the high-end instrument test of the General Administration of Mingde. If Sun Qinling, like Hao Yun, belongs to the ancient god beast program and can't find it, that's normal. Therefore, whether Sun is a translator is also a big problem.
From the above three doubts, we can infer that Guo Jingfei's appearance is definitely not as simple as making fun of. What happened in his three doubts can also be said to be three tables, which proves that his identity is not simple. I believe that in the next plot, Guo Jingfei will also appear on the scene.
