A week later, the valley of the Endless Mountains.

Since the nitroglycerin test, this place has become a new weapon testing ground—it's closer to the North Slope Laboratory, and it's hard to attract public attention no matter how much noise it makes. With the increasing development of the Misty Forest, the flow of people inside and outside the Northwest City Wall is far from what it used to be. The previous method of drawing an isolation zone in the suburban grasslands for testing is obviously not very suitable.

Considering that the power of weapons will further increase in the future, moving the testing ground has become a natural thing.

And what Roland wants to test this time is the single-soldier anti-devil grenade that was previously decided to study.

Due to the progress of the overall industrial level and the sufficient preparation of information in advance, the weapon took only five days from trial production to actual shooting, which can be regarded as creating the fastest record in the history of Neverwinter weapon research and development.

Of course, this is also inseparable from the particularly simple structure of the single-soldier grenade itself.

In another world, even extremists with five fighting ability can make giant RPGs out of gas tanks and drain pipes, and install pickup trucks to become multi-barreled self-propelled artillery, not to mention Neverwinter City with a complete industrial system support.

"Just aim the warhead at the target and pull the trigger, right?" Elhia asked with interest, rolling up the launch tube with her tentacles. Obviously, as a former high-ranking Holy Guard Warrior, she is full of interest in the new firearms, especially since this weapon was specially developed for devils.

It's just that this scene seemed a bit strange in Roland's eyes.

A sarcoma monster with a huge body and covered in tentacles is almost a regular in horror stories. Some of them shoot light from their eyes, some rely on knives, guns, iron shields, and some rely on powerful suction cups and secreted special liquids to fight the heroes... but holding an RPG? Uh... something doesn't feel right.

However, letting the Primal Vessel serve as a tester is also for safety reasons. Once a single-soldier grenade misfires and explodes, the soldiers operating at close range basically have only one ending, and even a God's Punishment Witch will not be much better. Only the Primal Vessel can extend its tentacles to a safe enough place to avoid tragedy.

"Don't point the tail at yourself or others," Roland coughed twice, "Start."

Elhia nodded her main tentacle and pressed the trigger.

A flash of fire instantly shot out of the chamber, flying straight towards the target a hundred meters away.

After drawing a shallow arc, the warhead accurately hit the bottom of the target... With a bang, the iron box used as a target rolled back two times, looking unscathed.

Compared to the earth-shattering fortress artillery bombardment or the sky-covering napalm flames, this can be said to be the smallest test. In fact, not to mention the explosive flames, even the dust and gravel that were stirred up were very few, and were blown away by the mountain wind in less than a few breaths.

"Uh..." The scene was a bit awkward for a while.

Only Roland smiled, "Go and get it and take a look."

Soon two God's Punishment Witches carried the iron box back.

"This is..."

Only when everyone observed up close did they notice that the bottom of the box was mottled white, as if it had been burned by something. And in the center of the white spot was an inconspicuous dent, about the thickness of three fingers.

"Did it penetrate?" Pasha asked curiously, "Although the speed at which it flies is not slow, it is not that fast. At least the bullet is much more noticeable... A revolver rifle can't penetrate this box, right?"

"Even a Mark One heavy machine gun may not be able to do it," Elhia leaned over, "This iron coffin is completely modeled after the stone pillars projected by the Spider Demons. Each direction is covered with a finger-thick steel plate, and it is not so easy to penetrate. By the way, isn't there a test product inside? Let's open it and take a look."

She stretched out two tentacles, lifted the heavy box lid, and everyone present let out a low exclamation.

In order to simulate the devils of the stone pillars, several live chickens were stuffed into the box in advance and hung on the box wall with iron wires. But now, only a few pieces of broken meat and a layer of burnt chicken feathers remain inside.

"It seems to work well," Roland nodded with satisfaction. He was not surprised by this result. Instead, it was even more rare that Elhia could achieve a hit in the first test shot—according to his idea, at least five or six shots would be required.

The lack of dazzling flames and deafening roar were all expected. How much equivalent, how much light it brings, this is an unbreakable principle. But if you want to fill in more equivalent, it will cost you, and the first thing that will be affected is the rate of fire.

On the basis of a fixed amount of propellant, the larger the warhead, the greater the resistance; the heavier the warhead, the slower the rate of fire. In order to improve the hit rate of high-level devils as much as possible, Roland gave up the over-caliber charge advantage. The grenade is almost the same size as the forty-millimeter barrel. The front section is conical to reduce friction with the air.

From the shooting results, the warhead performed very well in terms of flying speed and stability. Although the size has shrunk a lot compared to Iron Fist, the shaped charge warhead is more than enough to deal with ten-millimeter armor plate—and the equivalent thickness of the former is already comparable to the projected stone pillars of the devil.

"Do you think this weapon can hit high-level devils?" Roland looked at Pasha and the others.

"Um..." The first to speak was Elhia, "There are strong and weak among the high-level devils, such as extraordinary and extraordinary beings. It is not good to generalize. If it is speed-type, or a Devil Slayer, to be honest... the probability of a frontal hit is not high. Even if they see the grenade has been fired, they will have enough time to dodge. But—"

She paused slightly, raising her tone several notches, "This is definitely an epoch-making weapon, Your Majesty, because it levels the gap between devils and mortals, making it possible for quantity to win, and no words are enough to praise it!"

"That's right," Pasha followed with a smile, "It's almost unimaginable that mortals can hurt high-level devils. If we had such weapons in the Taquila era, Nataya would probably wake up laughing in her dreams."

"And I have another way to greatly improve its hit rate." Elhia waved her main tentacle.

"Oh?" Roland looked at her, "What is it?"

"Let the God's Punishment Witches use it." Elhia's voice was full of excitement, "The only ones who can compete with high-level devils are transcendents—if you shoot close to the face, even the most powerful enemy will not be able to dodge this blow!"

"Don't worry, since it's a single-soldier weapon, we will naturally strive to have one for everyone," Roland smiled, "God's Punishment Witches are no exception."

The next test is to further increase the power on the basis of ensuring the rate of fire and manufacturing cost, he secretly calculated. In addition, the characteristics of over-caliber should not be wasted. High-level devils run fast, but those deformed parasites are not so fast. Considering that they will eventually have to attack the cities of the devils, there is a possibility of encountering Spider Demons in street fighting, so it is also necessary to pre-research new ammunition.

While Roland was thinking, the guard suddenly brought a message.

"Your Majesty, the team you sent to Wolfheart has arrived at the inner river wharf, and Lord Shawn is back."
