With this doubt, I found a way to visit the only music teacher on the island, who was Keiji Aso's initiation teacher on the piano. As the only music teacher on the island, since Keiji Aso and Kameyama are childhood friends, it is clear that their music lessons are taught by the same teacher. And from that music teacher, I learned one thing—"

Taking care of himself, Gao Yuan continued:

That is, due to the lack of teaching resources on the island, the teacher did not teach music staves. If it weren't for Keiji Aso, who showed good musical attainments at that time and was recommended by this teacher to go to a school in Tokyo, otherwise people born on this island would basically only be able to read simple notation-

Therefore, I couldn't help but think of a possibility, that is, when Keiji Aso secretly communicated with Kameyama and others, the code used was actually written in Jane, so that the score that Keiji Aso left behind in the end with the stave, in fact, the four of them couldn't understand it at all, so there was a chance that the score could be preserved.

However, although there is some truth to this result, after careful consideration, I still vetoed this possibility-

"If Kameyama and others already knew that music scores could be a code for conveying information, then whether they were composed in simple or five-line composition, Kameyama and others would notice something unusual. Moreover, it is not difficult to understand the staff, as long as you find someone who understands music theory and convert the staff into simple notation.

Therefore, after this conjecture was denied by me, since I already knew that Kameyama and the others might not understand music staves at all, it was inferred from this that it was possible that they did not need to understand it at all?

"After all, taking advantage of overseas performances to smuggle illegal drugs and then ship them back to China through the hidden openings of the piano...... Now that the entire smuggling route and process have been clearly regulated, is it really necessary for Keiji Aso and the four of them to have room for communication with codes? ”
