All the equipment is connected to the energy, and Lin Xi is already immersed in work. When she finished building the reactor of the pulp power furnace, as soon as she looked up, she saw Chu Jun standing there in a daze.

"Jungui, what's wrong with you? ”

Chu Jungui woke up like a dream and said, "I just thought of a question. It's okay, I'll go chop some wood first. ”

"Why are you thinking so distracted?" Lin Xi was a little curious.

"I think our firepower is too weak, and if we can be a little stronger, we don't have to leave the first base. ”

"Our firepower is actually not weak, although I am not as accurate as you, but the comprehensive firepower is equivalent to a squad of regular troops. You are at least equivalent to a platoon, so together, we are close to the firepower of a reinforced platoon. ”

Lin Xi: This can't be said to be comforting, but a fact. The firepower of the reinforced platoon with two people is completely at the level of the king of soldiers.

However, Chu Jungui shook his head, "It is far from enough to strengthen the platoon. If we want to gain a foothold on this planet, or take a step back, and find a way to survive, we need at least the firepower of an ordinary infantry division. I think the firepower of the third-level agents is probably more than one division. ”

"They've already built an army, and we only have ourselves. ”

"Even if it's just the two of us, it's not like there's no way to increase the firepower. Chu Jun raised his pistol.

Lin Xi couldn't cry or laugh, and said, "You don't want to throw nuclear bombs around, do you?"

However, as soon as the words came out, she herself was stunned, and said to herself: "Yes, why not?"

This time it was Chu Jungui's turn to be taken aback, and hurriedly said, "Wait, I didn't mean that." It's better to be a little cautious with nuclear bombs, after all, we are not fighting in large corps. ”

The results of both uses of the fission bomb were not very pleasant, and both left a slight shadow on the test subject. This kind of weapon, which is very likely to injure people and self-harm, even the test subjects feel that they need to be treated with caution.

"Then what do you want to do?" Lin Xi asked.

Chu Jungui frowned and said, "Let me think about it...... Well, first of all, you need to be able to kill the beast with one shot. In other words, the power has to be doubled. ”

"Can you stand the recoil?"

"I'm fine. Chu Jungui glanced at Lin Xi and did not continue.

Lin Xi gritted his teeth and said, "I'm fine, as long as I practice more, I can adapt." ”

Chu Jungui looked at her with some concern, and Lin Xi stubbornly glared back. Adapting to recoil is largely based on absolute strength, and both of them have suffered multiple damage to their survival armors, and the accuracy of their auxiliary power has also decreased, so they need to rely on their own strength to counteract recoil.

The test subject can exponentially explode when necessary, but Lin Xi is a girl after all, and her strength and test subject are not at the same level.

"Don't worry about it now, maybe there's another way. ”

"What's the solution?"

"Let me think about it. ”

Chu Jungui established a mission: to increase firepower without increasing recoil.

The chip quickly gave a bunch of solutions this time, the top of which was: rocket extended-range explosive bombs. Chu Jungui looked at this plan, how to look at it and how to feel familiar. This time, the political component finally did not add to the chaos, and found out the historical version of this plan from the historical data, so Chu Jungui suddenly realized.

Isn't this a repeating version of an RPG?

Seeing the RPG in history, Chu Jungui suddenly became enlightened. The so-called firepower, academically speaking, is the energy equivalent delivered to the target per unit of time.

In layman's terms, it is nothing more than fighting fast and blowing up hard.

As long as you have an idea, the solution is not difficult. After gaining insight into the essence of firepower, it didn't take three minutes for Chu Jungui, who got the bonus of chip computing power, to find a phased solution, but it was only a phased one.

The reason why RPGs in ancient times had a big head was nothing more than the need for charges, and there was also a place to place various fuses. With biomass explosives, the charge does not need to be so large, and a diameter of 20mm is sufficient. The killing fragment is easy to solve, and the cut bone fragment is buried inside.

The disadvantage of RPG is that the trajectory is not straight enough, so Chu Jungui reduced the gunpowder propulsion part and added a medicine pack. In this way, it actually turned into a rocket extended-range shell.

Chu Jungui redesigned the bullet chain or the 30-round magazine to feed the ammunition, and the continuity of firepower was guaranteed. According to the design drawings, this thing has a range of more than 3,000 meters, a killing radius of 50 meters, and the power of a single shot is roughly equivalent to seven or eight old-fashioned RPGs bundled together.

In order to fire such ammunition, the barrel and bolt material naturally required extremely high performance, and a biomaterial comparable to a superalloy was obtained.

A powerful killing weapon was thus made.

After the sample gun was made, Chu Jun returned to the flat end of the sample gun, aimed at a big tree a few hundred meters away, and shot out. In the roar, the big tree that hugged the thickness was blown up in the center!

This kind of power made Chu Jungui's brows stretch slightly, but the rate of fire still made him very dissatisfied. In the heat of battle, this thing can only shoot three shots per second, which is a bit unsatisfactory. It's just that the rate of fire has always been a hard wound for bio-made automatic weapons, and there is nothing the test subject can do.

Knowing this, Chu Jungui felt that he would make the bullet one size bigger, and there was nothing wrong with a 30mm caliber.

It's just that the caliber has changed, not only the power has changed, but all kinds of charges, ranges, and even the material of the gun body have to be redesigned. In the spirit of not wasting it, it seemed that this gun could barely be used again, and Chu Jungui had no choice but to forget it.

He handed the gun to Lin Xi and said, "This is my newly designed gun, you can try it." ”

Lin Xi took it silently, his hands sinking slightly. Not to mention the size, just more than 70 kilograms is not something that ordinary people can play with.

Lin Xi flattened, aimed, and a shot broke a double-leaf tree at the edge of the forest. The huge recoil caused her upper body to lean back noticeably, but her feet only slid back a little, and she didn't retreat.

"How do you feel?" Chu Jungui asked expectantly.

Lin Xi replied, "You call this thing a gun?"

"It's not a gun, is it still a cannon?" Chu Jungui looked confused.

Looking at his innocent eyes, Lin Xi was really speechless, sighed, and asked weakly, "Then what do you think is a cannon?"

Chu Jungui quickly flipped through the historical data, found the basis for judgment, and replied: "It's quite a lot, and all of them are cannons above 406mm, right?"

"406......" Lin Xi is also familiar with military history, and at this moment I want to ask what are the heavy patrol tops in the era of the home planet.

Chu Jungui didn't notice Lin Xi's strange appearance, he was staring at the design drawing, thinking about what kind of way to use to increase the rate of fire of this gun to more than 400. In fact, 400 rounds per minute is not enough, and 600 is considered a qualified assault rifle.

For a small caliber like 20mm, the rate of fire should be higher.
