Kudou Shinichi's password.

This password is actually quite simple. As long as you analyze it carefully, you will find that this is a very easy code.

1, this code is written on the title page of the diary;

2. This diary is a diary for recording cases;

This is Xinyi's diary.

What do ordinary people write on the title page of their diaries? Most of them are words that people think are very important. This is written in Xinyi's case diary, and obviously there should be some important words about the new case. Think about what he often said-"There is only one truth". So that's probably what this code word means.

Now that we know the general meaning of the code word. Then it is very easy to crack the code, which is also an important reason why I think it is not difficult.

In this code word, ※ appears 7 times, far more than other symbols, while in English, it appears far more times than symbols of other letters, leaving only spaces, so ※ should be spaces.

□ If the second letter appears four times, and at the beginning, it may be a consonant. There are only two words in the secret code, because this sentence means "there is only one truth", so these two letters are probably "is", which is often used with is. The first letter with high frequency should be T, and this word is there. So □ is T, ☆ is H, ≮ is E, △ is R, ★ is I, ▲ is S.

Then □ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ ☆ 97)

And○∝○○○○○○○○○○○○○○○○○○○○○○○○○○○96

This step should be obvious. According to "there is only one truth", only one letter and symbol is similar to the new one, indicating that ○ is O, while i◆ should be in, →or∞〓 should be the world, and onl↑ should be only. At this point, the secret code was solved:

There is only one truth in this world.

Is it simple?
