How about flat rubber bands in Yuan Bo?

Yuan Bo flat rubber band has light tension and high speed, which is more stable than traditional bows and arrows.

Flat slingshot can kill some smaller animals, such as poultry, but it is not suitable for hunting large animals. It can shoot prey from a long distance, but it is not suitable for car hunting because of the space inside the car. The power of a slingshot depends on its rubber band. Compared with the traditional circular rubber band, the flat rubber band can give the projectile a higher initial velocity because of its quick rebound. So it is more powerful.
