Huff finally I found the same case of the sound thing when
dumas's armor "heart" stop or his
armor looks like stopped function in
season 3 ch 66 is when yama command to load the
needle and same with the sound
inside the needle too, that sound is creaking thing in english
here and
here.
So there is no doubt that dumas's armor and it "heart" is some machinery thing that "alive" and control by dumas, if that is the real heart I doubt the sound when it stop will be creaking.
Found another same sound again on when prison on nest's game open here
raw and
eng TL.
When warp machine stopped by kraken, the warp machine when stopped sound like that too on
eng TL and
raw.
