“What is this?!”

Su Mo picked up the model laid out on the far left of the bed and asked curiously as he thoroughly examined it.

In terms of appearance, the model looked like a bazooka. It was cylindrical, and the interior was dark. It was hard to identify the ammunition that could be loaded inside.

Below the column was a decent shoulder pad, which looked like a short-range anti-aircraft missile in a civilized era.

However, there was one problem. No foreign races could fly in the wasteland yet, so there were no threats from a higher altitude.

‘Developing missiles?

‘Doesn’t it seem a little impractical?’

“Oh, you mean this? This is an air cannon! The rear of the long barrel is responsible for compressing the air inside. When the air pressure reaches its limit, you can press the trigger to activate it.

“According to a rough calculation of the finished product, the charging time of one shot is about four or five minutes, and the firing range is 120 meters. The power is roughly equivalent to… two detonators?”

Xiao Yu scratched her head and took out a stack of papers that detailed information about her gadgets. She flipped through the pages and handed them over to Su Mo when she found the documents of the air cannon.

The documents recorded her initial research and development process and even details of tackling the obstacles and eventually making a sample model.

The reason for the development of the weapon was very simple. Mountain Moon Territory was extremely poor but desperately needed a fatal weapon to eliminate their enemies.

After brainstorming ideas, Xiao Yu immediately thought of the cheapest option, air.

Unfortunately…

“The shortcomings of the finished products are simply intolerable. Not only do you have to carry a generator as a power source, but the insane noise produced by the engine can be heard clearly within a few hundred meters.

“On top of that, the charging time is about four to five minutes. No enemy would be stupid enough to wait in the same spot when in 100-meter proximity to wait for you to attack them.

“Thus, after testing it a few times, we had to put it on hold for now because I couldn’t think of a better way to improve it yet!”

The papers that she handed over noted the complete data obtained from the several

experiments that she had done in the past

Su Mo’s eyes flashed brightly, and a thought immediately surfaced in his mind after seeing that it could be compressed for up to fifteen minutes and reached the power of a small explosive pack.

The biggest problem encountered by the air cannon was the charging problem.

The shoulder carry design would be rendered useless if they constantly carried around a heavy generator.

The advantage of having free air ammunition was not enough to cover up the biggest flaw of the weapon.

However, if there were a way to solve the problem of the air cannon’s energy input problem and improve the loud noise it produced, this weapon would be very precious.

At least, it could produce a very good effect in an offensive and defensive battle when at a numerical disadvantage!

As for how to improve it…

Su Mo thought about the KF energy stones they used in the climbing car and could not help but smile.

He quickly turned his attention to another weapon.

“What about this one?”

The first weapon was easier to guess the general purpose of it just by looking at its shape.

However, the second one looked very bizarre.

It was like a scope that could be attached to a rifle and a bracket to hold up a gun.

Su Mo examined the model for a while but could not find an entry and exit hole for ammunition.

“This is an auxiliary aiming scope made by Xiao Yu.”

Guan Yuan, who was beside, began to explain before Xiao Yu could say anything.

“Majority of the people we recruited were ordinary civilians on earth and never went through shooting training. Neither did they go through any corresponding long-term tactical training, so even if we obtained a batch of guns, ammunition, and technological weapons, there was no way to improve our combat strength quickly.

“I thought that if we had a simple auxiliary thing to help everyone to get the hand of shooting quickly, we could save a lot of bullets needed for training and at the same time allow everyone to handle a gun without wasting resources.

“I brought up the suggestion, and Xiao Yu began to develop it and eventually came up with this auxiliary aiming scope!”
