The moon project reveals what will happen to Angela in the end of the ruined library. Judging from the current plot, Roland has been enlightening Angela, so the possibility that Roland is a tool person is not ruled out, but it is unlikely. Personally, I think Roland's true identity should not be the nine-level terminator he said, but the dark silence of color level.
brief introduction
Roland is very aware of the big and small events in the city. In Gabra's plot, he has directly doubted his identity, and Angela has more or less doubted it. This kind of experience is something the Nine Terminators can never have. And his wife is a top finisher (if Roland didn't make up her own story), it is probably a color scale. Generally speaking, if Roland is really just a nine-level crane tail, it will be difficult to get a wife even if he pursues it (Roland will hang up with a hammer).
In addition, Roland knows Cang Lan's residual sound, and knows that he has become a mental derangement, and wants to kill people and play musical instruments every day. From his descriptions, we can see that he doesn't appreciate what Dan Lan has done, and the dark silence is the last person to stop the "pianist" from playing crazy music. They have the same attitude towards "playing music".
