Why does Zhang Qiling often lose his memory in Tomb Raider Notes?

In the novel Tomb Raider Notes, many people must feel very strange about the amnesia of the mute Zhang. Why come to a critical moment, such as what's behind bronze doors, what's in the meteorite in the tomb of the Queen Mother of the West, and so on. These appetizing questions, he will selectively lose memory, or shut up. Why is this happening? Does dumb Zhang have anything to hide? For the specific situation, let's look at the detailed explanation of the first fake calligrapher in the world.

First of all, what is the purpose of mute Zhang's amnesia?

I have always been curious about this question, that is, what is behind bronze doors and what is hidden in the meteorite of the Queen Mother of the West? For these problems, perhaps the novel author Nan Pai's uncle himself didn't think clearly when he was writing. So avoiding talking about it can only make the dumb Zhang selectively lose his memory. Just like Wu Yuncun, the screenwriter didn't know what to do with the fat man, so he directly asked someone to knock him out. How simple it is!

Secondly, when filling the pit later, I found a very reluctant reason.

In the novel Tomb Raider Notes-Restart, the author also explains his little brother Zhang Qiling's amnesia. That is, as a member of the Zhang family, Xiao Ge is born with many mysterious powers, and his thoughts are often controlled by some kind of power. Once he comes into contact with some mysterious things, such as bronze doors and meteorites, the contents will activate the "formatting" function and he will lose his memory.

Especially in meteorites, my little brother also talked to the ancient "corpse" inside, which may be behind bronze doors, so these alien forces, through some ability, made my little brother selectively lose his memory, thus preventing the ancient secrets from leaking out.

Therefore, for my little brother's amnesia, the author once thought that my little brother might be a deformed premature baby married by close relatives, and he was born with staged amnesia. So it's a coincidence that he lost his memory in bronze doors and the meteorite. But the author's later explanation is not the case, which makes people feel specious. After all, Wu Xie also learned it in his dream, which is not necessarily reliable or clear.
