While at this moment, Li Hongyun was able to personally experience the power of the Divine Arm Bow in this slice of history.
The so-called Divine Arm Bow was actually a type of crossbow.
Because the pull strength and weight of a bow are limited, the more powerful the bow, the greater the force required to draw it, which meant its power was greatly restricted. No matter how strong a person was, the weight and frequency they could draw a bow were very limited.
But crossbows were different. Through the use of foot pedals to span them, crossbows could far exceed the power of bows. Plus, crossbows were simpler to use and had lower training costs.
The Divine Arm Bow was called a bow because it was a type of crossbow that, like a bow, was used upright.
