This is an unknown farm, if I really want to say a name, or it would be more appropriate to call it a wasteland farm, the partially collapsed tin hut on the ground is surrounded by cracked clods of earth, and the nearby plants are scarce, full of rocks and dust, and occasionally you can see a little bit of low yellow-green, some tenacious plants.

"There have been a lot of changes here, there used to be a few trees, but now they are almost a sand dune", Lydia gently covered her mouth to block the raging wind and sand, "It seems that what I said before is true, the groundwater level here has dropped, and the water can no longer be pumped out with ordinary pumps." ”

The door of the farm hut has long been gone, there is a thin layer of yellow sand on the ground, the furniture in the hut is also unused, the wooden materials are decayed, the steel materials are rusty and deformed, only some wreckage remains, Lin Ze looked around, and saw a broken ceramic toilet in a small compartment, and a ceramic bathtub with several large holes, well, good thing, save the effort of making blueprints, as long as it is slightly modified.

After a while, a thick bathtub made of S3 material appeared in a compartment, and Lin Ze then took out the deep sucking flower, controlling the roots of the flower to go down to the ground, as long as the groundwater does not disappear, or descends to the extreme depths of the ground, there is always a way to find a water source.

What is it? Is it another amazing burrowing plant? Lydia had seen Lin Ze make holes with plants, but she had never seen Shenji flowers, and the little boy next to her was even more dumbfounded, with roots growing on the hands of a big living person?

The flowers are blooming~ It's a big purple flower, it's so beautiful~ What is this, is it another magical plant, what is it for? Lydia had never seen this kind of flower that was clearly different from the wasteland plants since she was a child, could it be that she had brought it from the eastern continent? It is really possible that the Eastern Continent is the base camp of the Alliance of Controllers, it is said that there is a botanical research institute there, and many plants have been preserved before the disaster, and Lin Ze also happens to be a telekinesis controller.

"Okay, this flower can absorb groundwater and filter out harmful things, just gently pull the petals this position, and pure water can flow out from the middle of the stamen, Ledia, please help this little guy take a bath", Lin Ze gestured how to control the deep flower flowing water.

"Pure water? Pure water to drink? "Lydia seems to have grasped something important.

"That's right, that's the one~ That's how the water we drank before came from", Lin Ze was afraid that Ledia would be confused, so he specially explained.

"Uh~ Take a bath with pure water, you're too ......"

"It's okay, just let it go after washing, and the water will flow back into the ground, it's not a waste, where it came from and where it came from."

"This ...... Can I wash it together? "Lydia is still a little cautious, bathing on the crystal earth is a luxury, there is very little clean water, and the water in nature must be heated to boiling and sterilized, and then cooled before washing.

"Of course, you guys wash it first, and then it will be the two of us", Lin Ze pointed to the little boy and himself.

……

The little boy sat on a box taken from a motorcycle shelf, looking at Lin Ze without blinking, especially the liquid floating in the air in Lin Ze's hand, which was still an iron tube gun before.

Lin Ze is very headache now, what to do with the T5 material after burning, he has used a lot of 5.56 firearms that he is familiar with, and the firearms need to be disassembled and maintained frequently, so I don't know which gun type to choose.

First of all, it is necessary to choose a convenient modification, that is to say, it can change the use of the firearm by replacing a few parts, secondly, it is convenient to install all kinds of external accessories, and it is easy to carry, and finally, it must also conform to the harsh environment of the crystal ruins and the aesthetics of the crystal soil people.

Lin Ze straightened out his thinking, and followed the routine of those large-scale firearms buyers in his hometown, they all put forward their requirements for firearms first, and then let the major manufacturers come up with sample guns to bid, and they can also do this, first determine what type they want, and then choose from their memories one by one.

Easy to modify, this is easy to do, there are guns can be changed in a variety of ways, easy to add accessories and carry, this is easier to do, there are tactical guide rails of firearms can be achieved, the most difficult thing to do is the latter one, not only to be able to use in a variety of harsh environments, but also to be in line with the aesthetics of the crystal soil people, here the aesthetics is not to say the appearance, the crystal people even the iron tube gun this crooked melon are used hi, the appearance they don't care, the key is to save money, less faults, easy to repair, convenient to recast these are the difficulties.

If you change to a place with a complete industrial system, these are not problems, Lin Ze can find a lot of matching gun types by patting his head, there are so many low-level cosmic civilizations, Lin Ze has bumped all the way up from the first order, and he himself can't count how many gunpowder guns he has been exposed to, and the gun types that can basically be popular among explorers are all proven mature products, but the industrial system on the crystal soil is seriously damaged, and there are wars everywhere, and ordinary people can only rely on things like the recaster to make items in the end, The key here is the material, the material is too few, and the characteristics are single, just like using the alloy used to make the gun barrel, which of course will seriously affect the various properties of the firearm, in his impression, a good barrel is to use some special processes, such as cold forging, chrome plating or something.

Alas~ From a different angle, this should be a big advantage for himself, Lin Ze has always had a headache The gun type here can be recast with a scanner as long as you buy one, and now there are some things that can't be recasted, isn't this a natural and perfect anti-counterfeiting means?

Lin Ze thought about it a little deeply, and quickly shook his head to drive away this currently irrelevant thought, forget it, first of all, try to choose firearms with uncomplicated materials, simple structure, and mature technology.

That's right, just choose it, short-stroke gas conduction piston, telescopic butt, rear-pull bolt, rotary bolt, the most important thing is to apply the modular system assembly, the modular system is very simple to understand, that is, the whole firearm is divided into several modules, and then in these modules are loaded with those small and fine parts, the simplest is to divide the upper and lower two gun magazine modules, the upper gun magazine module includes the barrel, the barrel guard, the gas guide system and the aiming fire control system installed on the rail above the barrel, etc., and the lower magazine module is the bolt, magazine, Grip and butt, etc., the advantage of this is that the combination of long barrel + magnifying sight + vertical foregrip and other upper magazine modules can be used as a medium and long-range combat configuration in the field, and the combination of short barrel + holographic sight + laser sight + short foregrip is used as an indoor complex terrain combat configuration, and the lower magazine module does not need to be changed when the time comes, as long as the upper magazine module is changed in more than ten seconds to adapt to the needs of different terrains, saving a lot of time for assembly and adjustment, and the advantage of modularization is here.

Wait, it seems to have forgotten something, although most of the metal parts can be barely used, but what to do if you need special materials such as the aluminum heat shield on the inside of the barrel guard, there is no such thing as aluminum at hand, forget it, I don't want to do so much, the crystal earth has thick skin, and you can't die if you burn it, not to mention, Lin Ze has now been able to make a low-tech but very practical gun, that is, the front grip, haha, you can't burn yourself.

Although the recaster on the ruins is not so versatile, but the work efficiency is high, after Lin Ze made the zero match of T5 iron pipe material, he changed the T4 alloy with S2 resin to remake a new gun, 5.56 bullets are a bit heavy, the charge is more powerful, I am afraid that the strength of S4 resin is not enough, so I simply use S2 resin, anyway, I also made it for my own use.

Lydia came out with wet light gray hair, aha, bathing with pure water that costs money to drink, it's enjoyable to think about, although a certain little baby who is desperately "struggling" in the bathtub gets water everywhere, it's really comfortable, huh? What's that, just like that for a while there are new guns? Lydia saw Lin Ze holding a gun with a compact structure and an extremely simple and exquisite appearance aimed around.

"What is this?"

"5.56's new rifle, I call it the Dead Demon, short assault type", Lin Ze's face was serious, originally he was going to name the Dead to stay, after careful consideration, in order to avoid uninformed people from doubting the intelligence of the gunsmith, it is better to simply call it the Dead Demon.

"Short assault?" Lydia is a little blind.

"It is used for short- and medium-distance combat, and it is not flexible to use it at close range with a long barrel, and we don't seem to encounter many long-distance firefights", Lin Ze is very calm, in fact, what he wants to say is that when there is no powerful sight, long-distance firefights are still forgotten, relying on mechanical sights, eyes may not be able to hit the target.

"What is this? Can you turn the peephole? Lydia pointed to the door at the top of the Necroc's straight magazine.

"This is a drum ruler, a hole-type door, and a columnar with a ring crosshair in front", Lin Ze explained, in fact, the previous impression of the prototype of the hawker submachine gun was that this combination of mechanical sights was used, but at the beginning, in order to save trouble, it was a low-value firearm with crystalline earth, anyway, the point 38 bullets were held down more, and it was directly replaced with a notched door and a flaky front sight to save time and effort.

"Can I try it?" Lydia reached into the air and hesitated to retract.

"Of course, but be careful when firing with live ammunition, I just got it, I haven't tested it with live ammunition", Lin Ze reminded out of caution, the T4 alloy barrel doesn't know if it can withstand it according to the specifications of the original cosmic civilization, he still has a lot of things to do next, he wants to make the matching long barrel and carbine barrel and the corresponding guard plate and other parts in case of emergency, but unfortunately, if there is no way to provide low-temperature energy at hand, he will definitely use the ice hydrolysis method to remake the barrel.

Oh, of course, before he started, Lin Ze almost forgot an important thing, that is, to open a can of beef jerky to grind the teeth of a freshly washed baby, otherwise Lydia would test the gun, and the little guy would not know where to run after being unattended for a while.

……

"What you say is true? You know the consequences of lying to us, right, this is an important research institute of the Department of Life Sciences under the neutral organization Ukiyo", outside a seemingly ordinary white building, there were many people crouching in the shadows of the alley not far away.

"Of course I know, that person is definitely the outside visitor you're looking for, and although she looks like an El, who of you have ever seen an El who doesn't even know the lingua franca?" The figure of a man hides in the shadows.

"Good, I hope this operation has a huge harvest! Otherwise, you know, the consequences of offending a powerful neutral organization at will...... Action, it's your turn! A man in a long dark gray mantle with a hood grabbed the man's hand.

"Then my pay ......" The man hesitated.

"Don't worry, yours are indispensable, as long as you grasp the target, your share of the divine power potion must be indispensable, go quickly, it's time for you to behave, the CNC encrypted laboratory protective door can only rely on you, if you show any flaws and can't deceive you, we will turn around and leave, and then leave you here, I will do it", the man in the trench coat pointed to the white stone camouflage gate in the shadow next to the white building, the laboratory gate will naturally not be the one on the first floor of the white building, behind the door is just an abandoned above-ground building, The real entrance to the research institute, according to the information of the Ryder man, is supposed to be a camouflaged protective door in the shadow alley of the building that looks like a normal wall, and then leads to the underground.

"Don't worry, I've been in and out several times!" The Ryder man stood up straight, patted the dust off his body, straightened his clean suit, walked to the gate alone in a big way, and then expertly pressed down on a spot on the wall, and then beckoned to the door, "I'm back, open the door!" ”

"Who is it? Applying to enter the graduate school? Do we have any recent invitations? "Immediately inside the gate is a guard room with two guards on duty.

"It turned out to be him, that soft-footed shrimp, when did he go out, why don't we have a record here?" Another guard looked at the images coming from the hidden camera outside the door.

"Was it before we changed shifts? Then he has been out for too long, why hasn't he been caught by those raiders as a wall ornament, it's a pity~" The guard sighed, a look of regret.

"Who said no, this kind of waste who eats soft rice, dressed decently all day but dangling around in the laboratory, wasting our resources, how much of the water from those water purifiers was taken by him to wash clothes and take a bath, I really don't know what the director thinks, will she look for this kind of man?"

"Okay, open the door quickly, I don't know what the director thinks, but if he doesn't open the door again, he will definitely go to the director to make a small report."

The button to open the door was pressed, all kinds of equipment on the wall of the hall began to operate, the huge locks at the edge of the door were retracted, and there was a heavy muffled sound, the round door slowly retreated, and the door of the research institute, which took a long time, was finally opened.

Before the two guards could see the people outside the door clearly, a light green energy ball suddenly flew in from outside the door and crashed into the guard room, and the huge energy released in an instant directly vaporized the guards and the indoor equipment.

"Drop~~Drop~~~" The poignant alarm echoed throughout the lab, "Alarm, the guardhouse lost connection, the guardhouse lost connection".

"This is the lab's self-test alarm system!" The Ryder man was shocked, "We need to hurry, or they won't be able to blame me if they escape through other secret passages!" ”

"Quick, rush in, target the central experimental area! Nothing else", the research map was sold clean by the Ryder men, and under the leadership of the dark gray cloaked man, a group of people quickly cleared the guards and fixed turrets that rushed along the way......

"You're learning the lingua franca so fast, can you tell me about your world?" In the laboratory, an elf sat across from the Rydell woman, "This substance in your body that slows nerve signals is completely unknown, so I can't do anything about it. ”

"Drop! Drip! A sharp beep rang out, and the Rydell woman connected to the communication terminal on her wrist, "What's the matter?" ”

"Director, intruder! He~ Your husband rushed in with the intruder, and we couldn't stop it right away, it's the one who controls it, the golden scepter...... Yes! The "......" communication signal was disconnected......
