Doomsday: I Build a Space Fleet

Chapter 72 Modified Mechanical Dog

Do you have any more questions?

The group exchanged glances and shook their heads.

"If there are no problems, then the meeting is adjourned."

Lorraine turned to leave, but in order to help them work better and eliminate instability more quickly, she decided to give them some hope.

"Once the situation in the camp returns to normal, some things can still be discussed."

"Mission accomplished!"

"Anyone can shout slogans, but give me some real results."

Lorraine waved to them with her back turned and returned to the ship.

"Ouyang Nian, let's get to work. How's your research on the design blueprints for Di Ting and Tian Gou coming along?"

Ouyang Nian patted his chest and said with a proud look.

"Don't worry, I've already figured it out."

"That's good. The patrol robot dog we're making this time is similar in size to the Listening Beast, but its aiming and firing system will use the same firing system that the Tengu uses on its back."

Ouyang Nian opened the 3D models of Di Ting and Tian Gou, stroking his chin as he pondered.

"Transplanting the aiming and firing system from the back of the Tengu to the Di Ting shouldn't be a problem, but how do we solve the issues of feeding ammunition and changing air cylinders for the air gun?"

After all, ordinary mechanical dogs are relatively small and have limited load-bearing capacity. Furthermore, the structure of an air gun prevents it from using a bolt-action mechanism like gunpowder weapons.

Lorraine and the others are currently unaware of how many rounds of ammunition the air cylinders mounted on the air guns can fire.

"Platinum, did we bring back the gas cylinder filling device?"

"Don't worry, we definitely took it. It should be in the maintenance room with the air gun now."

Lorraine greeted Ouyang Nian and said.

"Before it gets dark, let's test how many rounds a single gas cylinder can fire."

Led by Platinum, the two arrived at the maintenance room, selected two air guns, and then used the inflation device to fill the air cylinders with high-pressure gas.

While waiting for the air to inflate, Platinum took out two steel targets and placed them 25 meters away.

Lorraine and Ouyang Nian took out a gas cylinder filled with high-pressure gas, installed it on the air rifle, and then inserted a magazine loaded with 15 .22 ammunition rounds.

The two men stood in position as instructed by Bai Jin, raised their air rifles, and aimed at the steel target 25 meters away.

"Free fire".

A faint gunshot rang out, and Lorraine was the first to pull the trigger. The .22 caliber bullet struck the steel target 25 meters away, making a crisp sound.

Lorraine then emptied all the ammunition in the magazine at a rate of one shot per second.

After removing the magazine and inspecting the gun to confirm that there was no ammunition in the chamber, Lorraine released the safety, put the air rifle aside, and waited for Ouyang Nian to finish shooting.

"Slap...slap...slap..."

Ouyang Nian fired the last three rounds from the magazine and completed the gun inspection using the same procedure.

"Let's go and see how deadly this gun is."

Lorraine and the others walked together toward the steel target not far away.

Platinum frowned as he looked at the dents left by .22 ammunition on the steel plate.

"Is its lethality very low?"

Ouyang Nian frowned as she looked at Bai Jin, somewhat puzzled. In her memory, .22 caliber ammunition from an air rifle could still effectively kill small to medium-sized carbon-based organisms at a distance of 20 meters.

"The lethality is barely sufficient."

Bai Jin frowned, trying to find the right words to explain to Ouyang Nian.

"For small to medium-sized carbon-based organisms, .22 caliber ammunition from an air rifle can indeed inflict effective damage at a distance of 20 meters, but due to its specially designed bullet, it does not have sufficient stopping power, although its penetration power is sufficient."

Lorraine added a sentence to Platinum's explanation.

"That is to say, this type of ammunition can penetrate small to medium-sized carbon-based organisms, but its lethality is relatively poor."

After explaining to Ouyang Nian, Lorraine looked at Bai Jin and offered his thoughts.

"If we replaced the ammunition we're currently using with solid lead or steel bullets, would the lethality be improved?"

Platinum pondered for a moment and then shook his head.

"It improves when shooting at close range, but if the bullet flies more than 20 meters away, its accuracy and lethality are almost zero."

Lorraine nodded and fell into thought.

"Wait a moment, I'll be right back."

Ouyang Nian picked up an air rifle and ran towards the processing center.

Upon arriving at the processing center, Ouyang Nian placed the air rifle into its scanning equipment for scanning.

Before long, Ouyang Nian saw the scan results.

Air rifles are primarily made of metal (steel, aluminum alloy) and plastic. The barrel is machined from round steel, the receiver is mostly made of aluminum alloy, and the stock is made of plastic.

To ensure shooting accuracy and stability, the barrel has extremely high wear resistance.

The gas cylinder for storing high-pressure gas is made of aluminum alloy and can store 100 ml of high-pressure gas.

Ouyang Nian had Cleveland send the scan results to Lorraine and Platinum, and then she returned to the maintenance room with her air rifle.

Back with Lorraine and Platinum, Ouyang Nian presented her idea.

"Instead of trying every possible way to improve the capabilities of this racing air rifle, why not use it as an accessory and build our own PCP air rifle?"

Faced with the problem at hand, Ouyang Nian chose to solve it through his professional skills.

"First of all, the caliber of the air gun remains unchanged, still using the barrel of a racing air rifle; the firing mode is semi-automatic, referencing the firing structure of an air pistol."

"The gas cylinders can be made of carbon fiber, which is lightweight, has a large gas storage capacity, and can be used for a long time."

"The ammunition is designed separately, but that's outside my area of ​​expertise."

Upon hearing Ouyang Nian's solution, Lorraine and Bai Jin exchanged a glance and laughed.

"It seems we've been too focused on the guns themselves."

Platinum shrugged and started to act like a cheater.

"I'm just a user of the weapon, so naturally I only care about the performance of the gun itself. What does it have to do with me if you don't use your brain?"

While making excuses, Bai Jin pretended to be innocent.

Lorraine was speechless and could only roll her eyes at her before pulling her along to study the ammunition.

"The magazine was changed to a 30-round long magazine, and solid lead bullets were used as ammunition."

Lorraine took an armor-piercing slug from the ammunition depot in the maintenance room.

"The ammunition's construction can be modeled after the bullet of an armor-piercing slug, but the armor-piercing design at the bullet tip can be eliminated, and it can be replaced with a round-nosed bullet like a pistol bullet. A conical groove can be added to the tail to facilitate the high-pressure gas to propel the bullet."

After listening to Lorraine's design, Platinum added a crucial point.

"The ammunition must be designed in a way that allows people to easily distinguish the front from the back; otherwise, the time required to reload will increase significantly, and it will also affect the failure rate of the firearm."

Platinum was able to bring this up because she suffered greatly from using hunting air rifles during her recovery phase, often spending a lot of time distinguishing the front and back of the ammunition.
