Found it.

It’s called “Luffy’s Onslaught”

You can directly search it on Baidu to hear it and you can download it naturally.

Hey, I was trying to find it for my friend just now. I found it ~ I just want to tell you together. He said this music is very exciting.

But if you listen to it alone = = it’s okay. . .

I also found many others along the way. . . It's quite nice to listen to, such as 风をさがして mother なる海

There is also one that many people are looking for: /v_show/id_XMTgxNzMzMzcy.html This is the memoir and the one "... ding... started" is that. . . It sounds good (the second half)
