When the arrow passed through the left chest, I heard the sound of bones breaking.
The sound was very crisp, like a beaker accidentally broken in the laboratory. I looked down and saw arrows coming out of my back, with my blood and minced flesh on them. There were shouts of killing all around, the water of the Muddy River had been dyed dark red, and the horse I was riding had long ago fallen into the mud, foaming at the mouth.
I am Gu Beichen, a professor in the chemistry department of a university in 2024. Three minutes ago I was processing a batch of cesium elements in the laboratory, and now I was wearing tattered Ming army armor and being chased by a group of cavalry.
