Each of these modified weapons has its own merits, and it is at this level that each of the major weapons begins to show its unique advantages.

Ye Yuxuan made a careful comparison, and finally chose to spend 1200 points to purchase two modified MP7A1 submachine guns. Suddenly, these two demon transformation killers appeared in Ye Yuxuan's hands.

The body of the gun is dark, and the muzzle is equipped with a standard flame suppressor, which is slightly lighter than the standard MP7, which shows that the whole gun is made of a large number of alloys based on titanium. Near the butt there is a dark blue spear-shaped collegiate insignia.

Ye Yuxuan unloaded the magazine, and immediately found that this magazine was stuffed with a full 50 rounds of 4.6mm caliber bullets in a double-row manner, and this ammunition load had reached the level of the vertical magazine of P90.

"How does it feel?" Su Mu asked Ye Yuxuan's thoughts with a curious expression.

"It's not light, but it's not heavy, just right." Ye Yuxuan checked the body of the gun in his hand and replied satisfied. With that, he put away the two new guns and continued to browse through the assault rifles.

Ye Yuxuan used a standard M4A1 before, and he was already used to this kind of feel, if he replaced it with an AK rifle with great power and recoil, it would naturally be inappropriate, so the AK series was directly excluded. "Huh?" It seems that there is a weapon that has successfully attracted Ye Yuxuan's attention.

After spending 850 points, a modified HK416 assault rifle slowly appeared in Ye Yuxuan's hand. Then another 350 points were used up, and a brand new M320 grenade launcher was installed on the gun.

Even though titanium alloy is used as a raw material throughout, the total weight of this gun still exceeds the 4 kg mark after being loaded with a grenade launcher and a bunch of tactical equipment.

Ye Yuxuan looked at this legendary weapon in amazement, and it was this type of rifle used by the American Navy SEALs to shoot bin Laden. And the luxury of the accessories carried by this magic modified weapon is also staggering.

The 4x to 8x adjustable night vision sight, the M320 replaces the original front-mounted ergonomic grip position after installation, the muzzle is equipped with a standard flame suppressor, and an IR invisible laser collimator is also installed above the handguard, which happens not to block the main sight and can be used for auxiliary aiming.

Removing the magazine, it lives up to expectations, and there are 45 rounds of 5.56mm rifle cartridges neatly arranged inside, in order to increase the ammunition load, the magazine has been slightly lengthened, although the mounted M320 grenade launcher still only has a 1 round ammunition load, but it is indeed not wise to reduce the portability of the weapon in order to load grenades.

The barrel of the gun has been so modified, but what about the bullets? The Academy's modified weapons don't always use normal ammo, right? So Ye Yuxuan began to look for alternative ammunition for these two magic weapons.

Soon, Ye Yuxuan understood what it meant to be mad.......

All kinds of inhumane-looking ammunition appeared in front of Ye Yuxuan's eyes, if it weren't for the fact that the main target of these things was to summon beasts, these things would simply be anti-human benchmarks.....

In the end, Ye Yuxuan chose the most expensive depleted uranium alloy armor-piercing bullet to replace the traditional ordinary ammunition, and the magazine of this bullet has been specially treated to resist the radioactivity of depleted uranium.

The bullet head of the bullet is replaced by a steel core with a depleted uranium alloy, which is 2.4 times denser than the former, and the projectile penetration is proportional to the square root of the mass, making the penetration of this ammunition much better than that of a steel core bullet.

What made Ye Yuxuan even more rude was that the charge at the back of the bullet had also been improved, and the propellant originally used to launch the bullet was replaced with octanitrocubeane, which is currently the most powerful conventional explosive in the world, and its functional power is 2.7 times that of TNT, which means that under the same charge mass, the muzzle kinetic energy of the bullet is much higher than that of ordinary ammunition!

Damn, it is estimated that only the crazy people like Longinus, who have deep pockets, black science and technology, and high level of material science, dare to play like this, if they use the body of a gun made of stainless steel to launch this kind of ammunition, it is estimated that they will have to explode, Ye Yuxuan put away these crazy weapons, and his expression was crying and laughing.

Counting the 20 rounds of air-burst grenades with octanitrocubeane as the charge, a total of 4860 points were spent, and after repurchasing the weapons and ammunition purchased before, Ye Yuxuan only had 1681.7 points left in his account, and it was really like making money like running water, spending money like a waterfall, Ye Zi shook his head helplessly.

Looking to the other side, Su Mu also chose his two "new toys", and Ye Yuxuan recognized one of them at a glance: AA12 automatic shotgun! The theoretical rate of fire of this shotgun is up to 300 rounds per minute, and no one would want to try out for themselves what it's like to be blown away by 5 or 6 shotguns in a second.... It can even be equipped with high-explosive shells, and armor-piercing ammunition can pierce through half an inch of steel plates!

The other weapon looked a little familiar, but there was no way to name it, Ye Yuxuan compared the information, and was surprised to find that it was actually an XM25 individual airburst weapon.

Ye Zi snatched the XM25 from Su Mu's hand, removed the magazine and took a look, good guy! It is fully equipped with 6 rounds of 25mm fuel air bombs, a proper magic modification!

"What? Suddenly interested in the howitzer department? Su Mu quipped.

Ye Yuxuan didn't pay attention to his ridicule, but just concentrated on playing with this gun: "What is the ultimate range of your gun?" ”

"Hmm..... The information said that this weapon has increased the muzzle specific kinetic energy, the ultimate range of point target is 1000 meters, and the surface target is 1500 meters, because it is a blasting weapon, kinetic energy attenuation will not affect the lethality. ”

Ye Yuxuan handed the XM25 back to Su Mu with some reluctance, and said excitedly: "Practice it, I feel that this thing can be of great use." ”

"Of course." Su Mu put away the two guns, both weighing more than 6 kilograms, with a smile.

Next, Ye Yuxuan and Su Mu conducted a comprehensive test of the performance of the new weapon on the training ground, and the results were very satisfactory. At a distance of 50 meters, the depleted uranium bullet of the modified MP7 is enough to penetrate a 12.7mm thick steel plate, while the modified HK416 can do this at a distance of 100 meters, Ye Yuxuan is sure that this is absolutely unimaginable for the outside arms company.

As for those improved airburst shells..... If the airburst mode is removed and the contact detonation mode is replaced, a single shot is enough to destroy a lightly armored target, and you can imagine the power of fragments in the event of an air explosion of this ammunition.

After a short rest, the duo were back in front of the portal of the Sim Camp training ground, and they had to defeat the guy who had repeatedly given them a blow to the head, or else the lock would be an obstacle to their future development.
