Time passes and history rolls forward. No matter how much knowledge Shigure has learned, he cannot change the history in his memory. A drop of rain in the era moistens things silently and is ruthless. It can crush a generation, but it can also bring hope to a generation. The regrets on those old papers finally turned into a wisp of smoke and floated into the river and sea, drifting away with the current without making a sound.
Intention: History cannot be changed, and the rights and wrongs of the past will disappear the moment it ends.
