After taking a breath, Lan Guanglei continued: "Before the end of the world, this place was responsible for one-fifth of the country's firearms production every year, so Old Scar wanted to take this place so much. The surrounding ore vein resources are too abundant, and the content of antimony ore near is the world's first, antimony is a hardener for metals and alloys, as long as a small part is added to the alloy, it can greatly improve the hardness and wear resistance of the alloy. You can imagine how scarce this resource is after the apocalypse, except for our own town and the country's top brass, other people have no idea that this place contains a lot of antimony ore, and they don't know where Old Scar got the news and want this place so much. ”

"What I'm going to give you is a huge piece of antimony ore, which has been collected since the construction of this underground production line, and every time we find antimony ore with a purity greater than 90%, we will collect it and keep it for backup. But when the end came, for some unknown reason, all the collected antimony ore was fused into one, and our technology could not get even a single piece from it, and the lasers and explosives had no effect, and not even the diamond blade could cause scratches on it. We're out of his hands, and we hope you can get him. In the future, you must make a weapon for us that is famous all over the world. Lan Guanglei said that he was not calm when making weapons.

"Aren't you afraid that I will rob you?" Liu Xin smiled slightly and asked.

"A truly strong man, full of arrogance, looking down on the common people, certainly will not be as insatiable as a robber. If you're going to snatch it, you can kill me when I told you there's antimony here, so why wait until now? Blu-ray Lei shook his head.

"Then why are you sure that I can be a blacksmith? Or how do you think I'm a blacksmith? Liu Xin asked with a smile again.

"Sword, your sword, your sword is definitely made by a master-level forger, even if this forger is not you, it has an unusual relationship with you, otherwise no one would forge such a bullish weapon for a stranger." Lan Guanglei said affirmatively.

"That's right, I do have a friend who is a master blacksmith." Of course, Liu Xin would not stupidly tell others that he was a forger, and since Blu-ray Lei had found a reason for himself, he didn't mind using it directly.

"My guess is quite accurate, so will you agree? The future gives us a world-famous weapon! Lan Guanglei stretched out his hand and waited for Liu Xin's answer.

"Deal." Liu Xin directly nested Lan Guanglei's outstretched hand.

"Let's go, I'll take you there, if it weren't for our own forging skills, I wouldn't have given up this antimony ore at all, it's too precious." Lan Guanglei also said with some heartache, Liu Xin can also understand, after all, because of his own reasons, he has to give away a baby, and everyone will be unhappy.

Liu Xin didn't answer, Lan Guanglei is also a leader of forces, he complained casually and didn't continue to speak, but moved forward silently with Liu Xin.

Liu Xin followed the blue light Lei through the entire underground production line, Liu Xin was shocked by the huge underground production line, worthy of the construction of hundreds of years of place, the entire underground is a radius of almost 1 kilometer of the circle, half of which is full of various mineral materials, the remaining half is the production line and a large area of open space.

If Liu Xin is allowed to come in by himself, he will definitely be dizzy by the exact same material mountain around, fortunately, it is Lan Guanglei who brings himself in, so he doesn't have to know the way by himself.

Liu Xin followed Lan Guanglei and slowly came to a piece of silver-gray metal. This piece of metal is a few cubic meters in size, and Lan Guanglei also knows that Liu Xin can't take it away at all, this thing must be placed here, so he can only wait for Liu Xin to bring his forging master friend to come over and forge it directly in it, and there is no need to be afraid of Liu Xin defaulting on the debt.

"Are you going to tease me? How are you going to let me take this thing? Or did you not even think about sending me? Liu Xin couldn't expose the space ring in front of a stranger in Blu-ray, so he could only pretend to be angry and say.

"How is that possible? I want to see if you can cut through this ore with your sword, and if you can, you can cut it small and take it away in a package. Lan Guanglei also said with a smile.

"Hehe, it turns out that you are planning to do this, then our conditions will be renegotiated, I will help you cut the ore, I will take two-thirds, and you can keep the remaining one-third, but I will help you cut it into the size you need, as for the refining matter, forget it, but if you can give a reasonable price, I will also ask my friends to help." Liu Xin said as he used a detection technique on the antimony ore.

"Antimony rough, formed by the fusion of antimony ore under certain conditions, is a naturally formed item, and adding a small part to the refining process can effectively improve the hardness of each metal. The rarity of S-grade has an effect on metals below S-grade, SS-grade has half the effect, and SSS and SSS above have no effect. ”

"There is a new value, rarity, it seems to be divided according to the effective level, the rarity of the S level, the highest can be used to the SS level, but it is already good, it can be used to the SS level, and it should be satisfied, after all, it is a product of the earth itself." Liu Xin looked at the conclusion given by the system and thought silently.

"How's that going to work? Give you a maximum of one-half, and no more talking. Lan Guanglei pondered for a while, and then said, his tone was resolute, and there was no room for maneuver at all.

"Deal." Liu Xin said happily, and then he drew out the sword of the Brotherhood, and rushed forward in a hurry, slashing at the antimony ore.

"Am I overpriced? Agree so quickly, if you know it, you will press the price again・・・・・・" Blu-ray Lei thought a little depressed.

"Haha, don't be in vain, a piece of S-class dead thing, with A-level hardness and your own gas, it should be done, I originally thought I could get a third at most, but I didn't expect Blu-ray Lei to bargain with me." Liu Xin was about to hum a little song happily, but the movements in his hands were not slow, and the sword of the Brotherhood slashed directly at the antimony ore.

With a "bump", the sword of the Brotherhood was flicked open, and a large number of sparks came out.

"Cut, it's hard." Liu Xin shook off his somewhat numb hand, quickly turned off 100 times the gravity, and continued to wield the sword of the Brotherhood.

This time, Liu Xin not only did not wield the sword of the Brotherhood under 100 times gravity, but also injected some qi into the Sword of the Brotherhood, making the Sword of the Brotherhood sharper.

"Smack." The Sword of the Brotherhood was bounced open again, this time only causing a white mark on the surface of the antimony ore, still a certain distance from the cut.

"I don't believe it yet!" Liu Xin's stubborn temper also came, directly turning the qi on the surface of the sword of the brotherhood into a state of high-speed vibration, and the sword of the brotherhood also turned into a chainsaw.

"Woooooo The sound constantly rang out from the point of contact between the sword of the fraternity and the antimony ore. Although moving slowly, the Sword of the Brotherhood was steadily extending towards the middle of the antimony ore.

"At this rate, it will take at least a day to cut the ore in half, what shape do you want? I'll help you get your part right, first of all, you have to take care of the work. The happy Liu Xin also joked with Blu-ray Lei.

"No problem, it's just a matter of rice, it's a small matter, what we need is a cube with a size of 1 cubic centimeter." Lan Guanglei directly said a request that made Liu Xin almost vomit blood, one cubic centimeter, the size of a fingernail, it's not troublesome, Liu Xin just wanted to say no, but found that Lan Guanglei had already turned around and left, and didn't care whether Liu Xin agreed or not.

"Rub, Blu Lei, you dare to pit me like this, you wait." Liu Xin's roar reached Lan Guanglei's ears directly.

"Whew, it's good that the flash is fast, you dare to pit half of my antimony ore, don't squeeze your use dry, I'm really sorry for that half of the antimony ore." Lan Guanglei walked out evilly, humming a little song, ignoring Liu Xin's roar.

The next Liu Xin became a professional ore cutting worker, and in order to avoid Liu Xin, Lan Guanglei even asked Su Linling to send food to Liu Xin. At the beginning, it was okay, Su Linling just left after delivering the meal every time, and the next day she was still nagging next to Liu Xin after it was delivered, and on the third day, Su Linling even moved her sleeping bag to Liu Xin's side, except for leaving to get food during meals, it can be said that she stayed next to Liu Xin for 24 hours.

Although Su Linling was talking all the time, Liu Xin was busy cutting ore and ignored her, Su Linling actually said it vigorously, and the more she talked, the more she talked. On the fifth day, Liu Xin was going crazy, Su Linling kept talking beside him, just like 3,000 ducks barking next to Liu Xin, Liu Xin was not easy to catch up, so he could only speed up the cutting.

In order to get rid of Su Linling's verbal bombardment as soon as possible, Liu Xin began to improve the cutting method, at first it was just the vibration of the qi, and slowly the qi began to become sharper, and in the end, it was already a huge sword, and the qi in it was still vibrating at high speed, and the entire cutting speed was also increased by at least 5 levels.

"Phew, I've finally done it with Lan Guanglei, and I don't know where Su Linling's stupid girl went to sleep? I guess I don't want to sleep in a sleeping bag, I'm used to listening to her language bombardment every day, and I'm really a little unaccustomed to not hearing it today. Liu Xin wiped the sweat on his forehead and said, this is the ninth day after Liu Xin started cutting, the gravity watch can not only adjust the gravity, but also have a simple chronograph function.

At this time, it was officially the middle of the night, Su Linling estimated that she couldn't get used to sleeping in a sleeping bag, so she ran back to sleep on the warm quilt, Liu Xin didn't care where Su Linling went, rested for a while, and continued to start her work.

Early the next morning, Su Linling came back on time with Liu Xin's food, and sat silently next to Liu Xin without speaking.

"Hey, ran back to sleep under the covers last night? Don't come at night in the future, it's really uncomfortable to fall asleep in a sleeping bag, so go back to sleep on your bed, and remember to bring the food. Liu Xin's voice came directly to Su Linling's ears.

Su Linling simply replied with an "oh" word, if it was usually a lot of nonsense, it was actually silent today, Liu Xin also felt that Su Linling's state was wrong, but he didn't say much, his relationship with her has not yet reached the point where he has to take care of everything.

The two sides were silent like this, Liu Xin continued to cut the ore, while Su Linling was in a daze beside him・・・・・・
