"Not having to draw the bow saves a lot of time, but the speed still needs improvement. Also, if there was a soft pad at the bottom, it wouldn't make my arm sore," Tan Zhenghong shared his thoughts.

Wind Liyang nodded, "I'll tighten the spring a bit more and try using double springs."

"Yeah, and replace this with a bigger spring, so the force during the shot will be much greater..."

Qiao Duo'er and the others exchanged looks and obediently set the Sleeve Arrow aside to have their meal.

It was nearly midnight, and they were really starving.
