Since the warehouse was too cramped, Robin moved the mountain of discarded parts to the open space outside to make repairs easier. In the process of transporting, he also classified and differentiated these rags, removing some things that had been completely scrapped and unusable from the hill, and some things that could be easily repaired were classified by him as the work that must be completed today. Among them, the largest number is undoubtedly the light infantry standard folding shield.

The Light Infantry folding shield is a small hexagonal box the size of a watch, but when fully unfolded, it transforms into a hexagonal shield that protects 60% of the body. In combat, this light but extremely strong shield can effectively resist small-caliber energy bullets, and also has a certain defensive ability in the face of large-caliber energy bullets. Therefore, in this new era of general improvement of individual comprehensive quality, this kind of light infantry folding shield has been widely used, and its existence has also caused some subtle changes in the form of warfare, so that hand-to-hand combat has once again become a major link in warfare.

However, large areas of firepower coverage are still the main theme of war, and as the main defensive tool, there will be a large number of folding shield losses in each battle. Therefore, this kind of low-cost but efficient equipment has become a recognized consumable in the army, and in the main combat unit, soldiers can even go to the logistics department to receive a large number of folding shields at a time. However, such a good thing does not happen on Charon, at least, not at B-57 post, which is the garrison.

Robin had already checked that there weren't many intact folding shields in stock in the storeroom, and even with the Aubrey they carried with them, they could only sustain two or three skirmishes. This is definitely a dangerous signal in the current stalemate of Charon, even one less folding shield may lose a life because of this, so the work of repairing the folding shield has become a top priority in Robin's eyes.

But in fact, in the eyes of Robin, an expert with the level of a technician, the repair of the folding shield is completely wasteful. He doesn't even need a robotic arm, just a multi-purpose screwdriver, and he's able to fix 60 percent of the folding shields here.

The repair process wasn't actually complicated, Robin just took apart the broken folding shields, picked out the intact pieces of armor, and put them back together. As a result, the first folded shields to be repaired look completely new and have no problems using them.

After the first batch of folding shields were repaired, the second batch of repairs was a bit more complicated. Because although these armor pieces have not been completely blown up, they have more or less one or two bullet holes or deformations.

This part of the damaged armor loses the function of folding, and the folding shield that lacks this part of the function also loses its portable surname, for the infantry who need to travel long distances, the shield that is not conducive to carrying is undoubtedly of no value for reuse.

In the case of the main force, their logistics department will definitely dispose of this part of the armor as scrap. But Robin couldn't do that, because God knows when the next supply will be, so Robin has to use everything he can to use, even scrap.

It took a lot of time for Robin to use the heating function of the robotic arm to soften the nail piece again, and then use a welding torch to repair the missing part of the nail piece. Under this delicate repair, most of the armor pieces have become intact, and although they are a little worse than the new ones in terms of defense after assembly, they should not be a big problem as a backup.

After repairing the entire folding shield, Robin began to repair some of the broken guns. Compared with a simple folding shield, the repair of the gun is undoubtedly much more complicated, and Aubrey may not be able to disassemble the folding shield, but dismantling the gun, they will definitely not be worse than Robin, so these damaged guns are basically impossible to reassemble, and most of them have become scrap because of the damage of a few parts.

However, these scraps have another purpose in Robin's hands, because in the Tiger training camp, as a reservist, he not only learned the management of standard firearms, but also learned to modify firearms and make their own guns. According to their instructors, a qualified soldier must use everything at his disposal and turn them into the sharpest weapons. At this point, Robin is at the top of the pack even in the Tigers' training camp.

He expertly dismantled the pile of broken guns and selected some generic parts. In fact, although the firearms are very different in appearance, structure, and function, in the most basic structure, some parts are basically the same, but they cannot be used because of the mismatch of models.

Robin was able to modify parts with just one file in the Tiger camp, and now that he has a mechanical arm, it is naturally more convenient to change. If he wanted to, he could have made some alternative firearms with good surnames, but considering Aubrey and them, the guns that Robin modified were still relatively close to standard guns, but with some changes in appearance, and they looked relatively rough.

"Yo! What kind of gun is this? Are you homemade? ”

As Robin was concentrating on fiddling with his newly finished firearm, Aubrey, who had returned to the outpost, suddenly appeared behind him and snatched the gun from his hand and toyed with it.

"This is the MX8-change, the function is not much different from the MX8, but the rate of fire is a little slower, but I have tuned the crosshair, and it should be more accurate than the basic MX8." Robin wiped the sweat from his forehead and got up to explain.

"Oh?" A look of surprise flashed in Aubrey's eyes, and he casually threw the gun to Bart and Lee behind him, who also looked surprised: "Take these guns and try them." ”

“ok！ ～”

Lee, who was already eager to try, immediately picked up a few guns and climbed onto the scaffolding, while Bart picked up a few rocks from the ground and used the colors on the map as targets.

Soon, the sound of the rock being shattered, and the excited voices of Lee and Bart were heard on the scaffolding. It seems that Robin's modified gun made them very satisfied.

"Looks like I'm underestimating you."

Aubrey waved a repaired folding shield, and then looked at the small hexagonal boxes lined up on the ground, and his eyes couldn't help but sweep away the initial exhaustion, and his spirit became energetic.

"I'm no ordinary rookie." Receiving Aubrey's compliment, Robin raised his eyebrows proudly, and his heart was suddenly filled with a sense of accomplishment.

On the other side, Yarman saw Robin neatly classify and discharge parts and instruments, and couldn't help but nod appreciatively: "You have this skill, why don't you become a sapper?" ”

"I'm not just good at fixing things! ～”

"Oh?"

Feeling the dissatisfaction in Robin's tone, Yarman laughed happily, he glanced at Aubrey, and after getting Aubrey's approval, he patted Big Bart next to him on the shoulder: "Interested in trying our rookie?" ”

"Delightfully! ~" Big Bart pinched his finger bones with a 'click' and a cruel smile on his face.

"Come on, come! ~" Facing the red-bearded man with a height of more than two meters in front of him, Robin greeted him without fear, raised his head and asked, "What are you playing?" ”

Big Bart glanced at Robin's saber tied to his thigh, suddenly sneered, and took out a large Rambo knife from his back: "Play with knives." ”

"Knives?" Robin hesitated: "Play this ...... that will kill people"

"Are you scared?" Big Bart looked down at Robin with disdain, the large saber spinning nimbly in his hand.

"You're scared! ~"Robin was aroused by Big Bart's aggressive surname, he pulled out the saber neatly, and with a 'buzz', the high-frequency shock wave of the saber made the blade suddenly blurred.

When the high-frequency shock wave is turned on, the saber becomes extremely sharp, and can even cut through the alloy. In close combat, such a saber is even more threatening than a pistol, so the warriors who can play with knives in the army are often the most feared.

"Turn off the high-frequency oscillation, just play, don't really get crippled."

Aubrey knew Robin's level of fighting, so he asked Robin to turn off the high-frequency shock.

And his words sounded a clear hint to Big Barth, and the rough face suddenly lost the smile of contempt and became cautious.
