In the life-and-death chess game, calculating the advance steps is not about how far you have walked, but how many steps you are away from the center point. At the same time, there are many paths that directly correspond to the center point area.
If Jiang Wang is now three hundred steps away from the center point, then his advance steps would be seven hundred. If he moves one step to the right and happens to be on another path that leads straight to the center point area, then his advance steps would remain unchanged,
However, if the path one step to the right does not lead straight to the center point area, then his advance steps would actually be a retreat, leaving only six hundred and ninety-nine steps.
Due to the complexity of the life-and-death chess game, there are often times when detours are necessary, thus it's common to waste time and strength in vain without making much progress.
