Every line segment was about one millimeter wide.
"As long as I thrust with my sword from different distances and angles, and each strike accurately hits the pre-set mark, I will be reaching my third target: the millimeter-level accuracy."
With the help of a first door panel, he came to the playground. Relying on the basketball fram, he stood it upright, then fetched two tables to secure it, preventing the door panel from sliding.
Preparation was done.
Li Shi held his sword about a meter away, staring at the door panel, selected a stroke mark and struck it with his sword.
Thud!
The blade was as swift as an arrow, precisely striking on the mark.
"It's indeed simple, as long as you have a hand."
Li Shi took out his sword and stood still, looking at the sword indentation in the middle of the stroke mark and smiling with satisfaction.
