The transformation of the light sniper rifle is very smooth, with successful examples, the second modification will of course be much simpler, it only took a week, and a dozen light snipers and a dozen pistols were all added with two runes to complete the transformation and upgrade.

It is still impossible to hit a humanoid target more than a thousand meters away, not because the modified gun is not good, but because the scope is not good, and the quadruple optical zoom is still too small, so it can only attack humanoid targets within a kilometer.

Even Li Yunfei himself can only attack humanoid targets about a kilometer away, and no matter how far he goes, he can only rely on Meng, but the power of rifle bullets has increased a lot, but it has not increased by two times like pistol bullets, but has only increased by about double.

It can probably be concluded that the effect of the energy acceleration array can make the passing bullets superimpose an initial velocity of about 800 meters per second, the pistol bullet is slow so the initial velocity of 800 meters per second is increased by two times, and the rifle bullet has a speed of nearly 800 meters per second, so it is only doubled.

The velocity of the bullet is as high as 1600 m/s, and the power is of course much higher than that of ordinary bullets, although the recoil will of course be increased, just because the use of these girls looks soft and weak, but in fact the physique is much stronger than that of the men in the prime of life, so those recoil are harmless.

In principle, you can actually improve the bullet faster, for example, you can build two or even three formations, but the recoil is too big, it will greatly reduce the shooting accuracy and miss, no matter how powerful it is, it is useless, of course you can design stronger weapons in the future, but now it can only be used like this.

Body armor is really not easy to get, making iron armor too heavy affects the action, but it is more likely to cause casualties, and making leather armor and cloth armor and the like, with the current materials is simply unrealistic, and you can't add a solid formation, that strong formation is only effective for metal, and finally simply gave up super armor.

I got some colorful camouflage helmets and made them colorful, as soon as you enter the grass and woods, it is difficult to find, and in addition, you can strengthen the speed exercise as much as possible.

A dozen people each have a standard light sniper, a pistol, a combat dagger, and usually always carry a tactical backpack with some dry food and drinking water, plus up to 600 rounds of rifle ammunition and 200 rounds of pistol ammunition.

Of course, the range of action of these girls now is not all within the scope of Jiuhua Mountain, Li Yunfei just explained that as long as they go out in the morning and come back in the evening, they can go wherever they go, of course, the three of them must act together as a group, so recently, they often go down the mountain to go around.

Only Xiao Chen can't find the team, can he go down the mountain alone, he always looks at Li Yunfei with resentment, and the file is even more resentful about those eldest sisters, it's too unrighteous, why can't he bring himself to play?

The three-person squad acted together, of course, there was no accident, if the little rascal who didn't open his eyes, he could beat them up without using a gun, if he really encountered some bandits, he would eat black and rob the other party in minutes, and inadvertently let the public order be much better within a range of dozens of kilometers near Jiuhua Mountain.

Of course, the national government can't care about these elusive women, and now all the energy is on the battle of Xuzhou, in fact, Li Yunfei has also been paying attention to the battle of Xuzhou, in fact, he will occasionally go down the mountain to sneak attack some of the devil's strongholds, but it can't change the overall situation, but the city of Nanjing is still Li Yunfei's back garden, and occasionally he will go there when he goes down the mountain, and if he finds some valuable targets, he will sneak attack and eat away at the strength of the Japanese army. Don't look at the sneak attack, it only caused hundreds of losses to the devils, but it was attacked several times, and there were thousands of people in total, and Li Yunfei was specifically looking for those officers, high-ranking officials were the best, and the squad leader didn't dislike anything......

Although the broadcasts I heard were all about how brave the national army was, how the devils were fighting, and so on, the actual situation was quite tragic, and the devils actually used chemical weapons on a large scale, causing quite serious casualties.

After the Japanese use of poison gas bombs was exposed, although there was a lot of criticism of Japan's protests in the international community, it was only a protest, and there was no substantive action at all.

Now there is more movement in Europe for Japan and Germany, but in fact the movement is not so big, but it happened in Europe, and it was Germany, which lost World War I, actually annexed Austria. The once defeated country, now showing its fangs, will of course be very worried.

……

Every morning at eight or nine o'clock, if Li Yunfei is free, he will also give classes to more than a dozen subordinates, teaching some basic knowledge of mathematics, physics and chemistry, as well as some scientific knowledge, although he is only a third-rate university graduate, but a group of primary school students is still more than enough, well, maybe Yumo culture is higher, but your mother writes knowledge, and Li Yunfei is still very rudimentary.

"Brother Li, haven't you always said that energy is conserved? Doesn't this pattern consume energy to accelerate the bullet? After a physics class, Xiao Chen was really a little confused, so he couldn't help but ask questions. In fact, the doubts of the other girls are just that they dare not ask, because they are questioning the authority of the eldest brother.

"Well, the conservation of energy is indeed true, but the energy in this rune array, just like the wind and rain on the earth, can form a cycle of its own! While consuming, it will also be instantly replenished and regenerated! ”

“…… No, Brother Li, didn't you also say before that the climate change on the earth is completely due to the temperature difference caused by solar radiation, and the evaporation of water vapor, could this rune still absorb those solar energy? ”

"Well, that's not it, Mithril is made of dark energy infusion that is different from this world, and after forming a stable cycle, once some is consumed, there will automatically be dark energy from other places to fill it, unless the balance of this cycle is broken, otherwise the rune array will not disappear if it forms a force field!"

"If that's the case, then why when I wipe the gun, the brush has reached into the barrel, and I don't feel the force field, if it accelerates automatically, it stands to reason that when I put something into the barrel to clean up, it will definitely be ejected!"

"That energy array has been running, only needs to be activated to have a special force field born, and the violent vibration impact can instantly activate the energy array, just like the saturated liquid made of starch, your fingers can be gently inserted into it, if the speed is too fast, you will break your fingers, the principle of the force field is somewhat similar!"

"So how did dark energy appear, and why did it have dark energy?"

“…… I don't know! ”

"It turns out that Brother Li also doesn't know!"

"Nonsense, I have more questions than you, and I don't even know why I know this knowledge and why I am here!"

"Brother, you see that we are all almost trained, and the devils are still slaughtering our compatriots, so can we go to the battlefield?"

"Yes, we can all accurately hit targets 800 meters away, we can snipe devils from afar, change places with one shot, and ensure that we will not suffer."

"Yes, big brother, we are all masters now, a few days ago, Chunhua Xiaoxuan and I successfully eliminated a wave of bandits who robbed houses."

“…… Well, you have a total of four squads, divided into two groups, two squads are stationed here, and the other two squads go to Nanjing and Shanghai for a generation, and use guerrilla warfare to sneak attack the supply lines of the devils, and the first and second squads will set off tomorrow, limited to half a month, and they will come back to change shifts after half a month! Li Yunfei finally decided to let these girls go to a higher level of sneak attack on the supply line, if such a super special force is used in the frontal battlefield, it is a waste of talent, only sneak attack on the enemy's supply line, and destroy the self-meeting system, what is the most cost-effective.

"It's the captain!" More than a dozen people stood up in unison and saluted.

"Big brother, what about me, I won't be left alone, right?"

"You're still a minor...... Well, you can also participate in the action, Yumo, you take care of it! Seeing that Xiao Chen was almost depressed, he still agreed.

"Brother Chen, when you act, you can't be impulsive, you young people are the most impulsive and will do bad things!"

"I promise to hear you."

"Words can be said in the front, don't listen to the command, don't want to join my team in the future!"

"Yes, big ...... Captain! "I wanted to be called the eldest sister, but now that I am really joining the team, I should be called the captain.

"Don't scream, I'm the squad leader, and your brother is the captain!"
