Chen Xu glanced at the data in the book and nodded, "Well, not bad. We can put a small batch into production for transitional use. We need to find a way to improve the accuracy as soon as possible."

"yes."

Pei Zhiyuan's face flushed and his heartbeat became disordered. She just held his hand in public and took him running in front of everyone.

After three years of living together day and night, he has already developed feelings for her.

It should be said that he had feelings for her from the beginning, but he had been suppressing his feelings and had not dared to say it out loud.

At the beginning, he was Hua Guoshi's lackey, a rebellious son who killed his father. How could he dare to be touched by the moonlight when he was stuck in the quagmire?

Later, he was a coward. He watched Xue Yan fleeing in panic and did not dare to step forward.

Later, he watched her become depressed and numb, but he was still a coward and did not dare to take that step bravely, for fear of touching her sensitive spots.

“Miss Shen, what are you going to show me?”

She walked over to a cloth-covered rack and lifted the cloth.

I saw a strangely shaped iron weapon with a wooden handle placed on the shelf.

There are also some short weapons next to it, all in the shape of crossbows.

Pei Zhiyuan asked curiously, "What is this?"

"A blast-type rapid-fire device. I call it an air gun for short."

"Is this a gun?"

"It's not a gun in the traditional sense. It's a long-range weapon loaded with steel spindle-shaped projectiles, but its power and range far exceed those of a crossbow. Most importantly, it's easy to carry."

"This kind of thing... requires internal energy to injure someone, right? If the enemy is wearing armor, it won't be effective at all, right?"

Pei Zhiyuan picked up a small bullet in confusion. It looked not even as sharp as a dart.

Shen Xu smiled, "Your Highness, the Regent, times have changed.

Let’s go to the parade ground and see for ourselves.”
