"You mean, um, improved counterweights!"

"How can it be improved?"

Shen Bing answered without thinking:

"Of course the counterweight should be changed into a one-piece type."

"There are many disadvantages to using baskets of stones as counterweights."

"The basket is easy to break and fall off. It can only hold stones, and it will swing back and forth during launch, which affects the accuracy."

"It's different to make a one-piece wooden box and fix it on the gun tip."

"It can even hold sand as a counterweight."

"Sand and soil can be found everywhere, especially when marching, the sand and soil can be discharged and temporarily loaded again before fighting."

…

"Master, are you okay?"

"Are you tired from working all day long?"

Xun couldn't help but cough, and raised his hand with difficulty to shake it at Shen Bing.

Shen Bing stepped forward and stroked his back and patted his chest. It took him a long time to regain his breath.

"I'm fine, I'm fine!" Xun Shuo said breathlessly, "Oh, my master... is already old!"

At this time, suddenly a cloud-piercing arrow flew into the sky.

Shen Bing couldn't help but frown.

"Is it Zhao Jun?"

"They came so quickly!"
