Heather sighed slightly, she knew Middleton was right. After all, she hasn't graduated yet, and occasionally eating a defeat or two won't affect her evaluation. It's just that it's still a little difficult to make her, who has always been arrogant, accept defeat.

She digressed the topic and asked, "How do you think our equipment should be configured next?"

Middleton had already thought about this problem, and immediately said: "I think that instead of using existing weapons, it is better to use the biomass series of weapons that they have developed." Their mechanical keyboard design ideas are very weird, but in addition, they are also good weapons with both power and stability. The most important thing is that the ammunition can be completely sourced from local materials, regardless of the fact that the supply will be cut off. ”

"Since you think so too, then I'll talk to them and provide us with a batch of biomass weapons. Before that, we're going to use our original weapons. In addition, you organize the information of the survivors, see what special talents they have, find them, form a separate team, and then see what kind of work can be assigned to them. ”

"Miss, are you going to work with them without reservation?"

"Why not? Have you noticed, what are the characteristics of their base?"

Middleton was also very observant, saying: "There are a lot of signs of battle. Most of these traces are consistent with the intelligence account of the beast tide. ”

"That's it. I'm afraid it won't be long before we have to face the attack of the beast tide. Let's not forget how high the casualty rate of the Lancers has been over the past few months. ”

"Understood. Miss, don't worry, we people, plus those two agents, should be able to resist a C-class beast tide. ”

"Alright, you go to work, I'll walk around the base. ”

Middleton was taken aback and said, "Miss, it's very dangerous here. ”

"I'm not going to get within 50 meters of the base. With that, Middleton could not object, and Heather walked straight out of the base.

Middleton was a little worried, but he also knew Heatherway's strength, and he was no match for Heather in one-on-one combat.

In the base, Chu Jun was guarding beside the workbench, picking up an alloy pipe that had just been made mixed with biomass, and was carefully inspecting it.

"What is this?" Hathaway's soft voice sounded behind him.

Chu Jun didn't raise his head and said, "Gun barrel." ”

Looking at the thick pipe that could be stuffed into a fist and was one meter five long, the little princess was surprised: "What kind of gun should use such a barrel?"

"Fifth generation mechanical keyboard. ”

The little princess suddenly remembered Middleton's evaluation, and suddenly became curious, so she simply sat down next to her and asked, "Can you show me the design drawing?"

"Of course. Chu Jungui didn't think much about it, and directly sent the design drawings over.

Now the design of the mechanical keyboard has changed from the initial new design to the current local improvement, the design workload is much less, Chu Jungui can rely on his own computing power to support, no longer need to use chips, so it does not affect the research and development of large-scale refining furnaces.

What appeared in front of Heather was a murder weapon of more than two meters, equipped with a huge drum as a ammunition feeder, but because the caliber was too large, it could only hold fifteen rounds.

"Why 72mm caliber?"

"According to the current properties of gunpowder and materials, this is the best caliber. ”

"Well, when the performance of biomass powder is improved in the future, and there is a better material formula, the caliber can be reduced while maintaining the existing accuracy and power." ”

"No, you can continue to increase the caliber while maintaining the current accuracy. ”

The little princess looked stunned, and then she came back to her senses and said, "This ...... The charge of one bullet of the gun is already more than 2 kilograms, and it is also a high-pressure stacked charge, so the yield of one shot is not more than 30 kilograms? Do you need a larger caliber?"

"Absolutely. The equivalent is always the better. Chu Jungui looked like he took it for granted.

"But who can use such a gun?"

"Me. ”

After blurting out, Chu Jungui realized that something was wrong with his words, and hurriedly added: "As long as it is placed on a specially designed gun mount, anyone can use it." ”

The little princess who was almost choked felt relieved.

She tried to keep a calm mind and continued to look at the blueprints.

At this time, the newly made bolt parts were spit out from the workbench, and Chu Jungui skillfully assembled the bolt and installed it on the barrel.

This mechanical keyboard does not have a high rate of fire, only three rounds per second. Even some semi-automatic rifles have a faster rate of fire than this. But don't forget, this guy is a 72mm caliber, and the range is more than 8,000 meters, even with the design of the rocket to extend the range, the recoil is still unimaginable.

Even a 100-kilogram muscular hunk will be swept away by recoil without using the auxiliary power of the armor.

The little princess thought that she could barely use it, but that was based on the fact that the micro-power of her warframe was three times higher than that of a normal warframe. With Chu Jungui's tattered survival armor, the little princess felt that he was even choking with a 30mm caliber, let alone directly up to 72mm.

Looking at it, Heather couldn't help but ask, "Can you really use this gun?"

"Reluctantly. ”

"If it's reluctant, why design it like this?" the little princess had a very inquiring spirit.

Chu Jun replied casually, but since she asked, she also said: "It's very simple, the only reliable thing in the face of the beast tide is firepower." Last time, the beast tide was very difficult to resist, and two people died. That's why I'm working on a more powerful mechanical keyboard to deal with the next beast tide. ”

"How big was the last beast tide?" asked Heather with a slight curiosity.

"By your standards, it should be two C-grades. ”

"Two C-grades?" the little princess struggled to keep her voice steady.

"That's right. Subject's attention was still on the gun in his hand.

"Are you sure you know what we mean by class?"

"The total number of beast tides is more than 1,500, and there are a mix of multiple beast species, including at least one black-winged empty beast, and multiple messengers to command. "Subject is backwards.

"Oh, by the way, I forgot you already have lancers under your command. However, just a few dozen of you can resist two C-class beast tides, and that would require at least two battalions of troops, right?"

Chu Jungui also sighed and said, "Indeed, so we also had casualties, and two people died. ”

“...... Two people. Heather tried to keep her expression from fluctuating, and too frequent surprise was a sign of unculture. And she also knows that showing respect to the deceased is a common practice anywhere. You can't say that you should have been wiped out, right?

After calming down, Heather smiled slightly and said, "Now that I'm on board, we should be able to deal with more war beasts." ”

"That's right, you can add another half of the C-level beast tide. Chu Jungui said seriously.

The smile on the little princess's face froze again.
