Although Su Yu's strength has recovered, there are still many things that are not clear. For example, how he came to this sunset city from Earth is a very strange thing.

In Su Yu's mind, all the strangeness appeared in that ancient tomb. It can't be related to that weird jade bead......

In Tianyi Academy, since all the students entered the nutrition cabin, the countdown has begun.

At the same time, the names of all the participants are displayed on a large screen on the outer wall of the building that one of the participants enters.

Time passed quickly, however, all the participating students still had zero points.

On this day, no one wakes up from their own independent world

There were a lot of people guarding the big screen, all pointing and talking about something. Among them, there are many teachers who have many students.

Topaz just glanced at the big screen from afar, nodded, and went back.

……

Su Yu's face was extremely strange, and he looked at Su Yu in front of him. A few days ago, Su Yu suddenly asked her for some strange materials, and then, he tinkered with it, and then he became a complete stranger.

Su Yu watched Su Yu change from a handsome boy to a big man, which was why she was sure that the person in front of her was Su Yu. However, it was precisely what he saw with his own eyes that Su Yu's surprise was even greater

Su Yu smiled slightly, touched his face casually, and instantly turned into an old man with a wrinkled face. Su Yu seemed to have seen a ghost, and his speech became incoherent: "You, you, how did you do it?" ”

Su Yu turned back into a big man again, and did not answer, but said softly: "Sister, let's go out" The ancient "face changing" technique, the disguise in the thousand-year-old strange combination of ninjutsu, and even the breath has completely changed. Su Yu didn't believe that anyone else could recognize him.

Su Yu found that he couldn't see through his twin brother more and more, the two were twins, they were close to each other, and even their cultivation talents were surprisingly similar. But since my brother recovered from his illness, there has been a mystery everywhere.

Su Yu went out in a sedan chair, and Su Yu played the role of a sedan chair driver. Out of the mansion, according to the discussion of the two, Su Yu returned to the house alone. And Su Yu was walking on the street.

Walking in the surging flow of people, but in a hundred or ten steps, Su Yu's appearance has changed three times. Sure that he was not being targeted, Su Yu walked around, looking for his goal.

The streets of Sunset City are extremely wide, the ground is paved with solid rocks, and there is a lot of traffic, people, and a row of prosperous scenes. There are many shops around, taverns, grocery stores, weapons stores, pharmacies, ...... Even the solemn cathedral, with its pointed roof towering like a sword, stands in front of the gate a white jade carved statue of a winged angel, lifelike, vivid, and extremely expressive. Su Yu stared at the tall church, and suddenly a sigh was born in his heart, the Bright Holy See is worthy of being one of the most powerful forces in this continent, and even a branch sect is so heartbreaking.

Turning a street corner, Su Yu stopped. Looking at the Magician Guild in front of him, Su Yu showed an interested look in his eyes, he didn't expect that there really was a person like a magician in the world. For the legendary spell, Su Yu was naturally extremely curious. But he just stared at the gold badge carved with a leaf carved into it for a moment, and then left.

Su Yu also saw the legendary mercenary union branch, with a sword and shield badge hanging in front of the door.

It's a spring morning, the sun is shining, the breeze is warm, caressing the face. Walking in such weather should have been a gentle and pleasant thing. But in the face of a country with very different scenery and customs in other places, Su Yu actually felt a faint sadness in his heart. …,

This kind of mood is like a world away?

Su Yu's expression moved, and he finally saw the destination of his trip, the blacksmith shop. The reason why I didn't go to the weapon shop was because Su Yu was used to using his own weapons, and now that he had lost the jasper bamboo, he naturally had to build another one according to the style. Only with the weapon at hand can you maximize your strength. Those table tennis and badminton masters in the previous life even had their own special rackets, which refused to be replaced for decades.

Su Yu had already walked through several blacksmith shops, but they were not very satisfied, these blacksmith shops had some high-sounding names, but none of them were in Su Yu's eyes. The things they created may already be considered high-quality, but they are still far from Su Yu's requirements.

Su Yu was bored for a long time, and sighed secretly in his heart: If the jasper bamboo is in hand, there is still such a lot of trouble to use. Jasper bamboo is an ancestral sword, which is not only extremely sharp, but also has other wonderful uses. And twenty-seven years of the sword has not left his hand, and Jasper Bamboo is no longer just a sword to Su Yu.

Anything that can accompany for decades will no longer be a simple thing, and the feelings contained in it can only be experienced by the parties themselves.

Su Yu looked up and saw an antique tavern at the T-junction in front of him, with a wine watch: Agarwood Pavilion Su Yu suddenly rose up and stepped into it. There are only a few guests sitting in the tavern of Nuoda, and there are several artistic conceptions in the tranquility, which not only does not feel empty, but makes people feel peaceful. With a hint of sandalwood in his nose, Su Yuyuan went up to the second floor, walked to a window seat, sat down, looked at the dark golden alder in front of him, and for a moment, he liked this feeling of tranquility inexplicably.

The wine glass has a long cylindrical body, a large flare-shaped mouth, a slope-like high circle foot, the wine is clear and transparent, delicate and green, and the aroma is overflowing, which is really worthy of being an agarwood pavilion. It is also a delicious barbecue, exquisite dishes, and mouth-watering. However, Su Yu is more interested in the people in this tavern, from Su Yu's eyes, these people are either rich or expensive, and among them are even more murderous, obviously not ordinary goods. And between the back and forth of the owner of this tavern, Su Yu couldn't see through it.

The city of sunsets, sure enough, hides the dragon and crouching tiger, and a small tavern is also extraordinary. Thinking of this, Su Yu was even more cautious in his heart.

……

"What, ten gold coins" Su Yu was obviously shocked, one gold coin is enough for ordinary people for a year, and if you drink a few glasses of wine and eat a few pieces of meat here, you will need ten gold coins

"Ten gold coins," the tavern owner said lightly, without the slightest emotion in his voice.

The drinkers around all turned their heads and looked at Su Yu's eyes, all of which were full of disdain and disdain. That clearly means that Su Yu is regarded as a poor country boy who has never seen the world.

Su Yu's heart moved, could it be that he had entered the legendary gold cave, and if the fat sea was here, the aristocratic circle in the story would definitely yell: You go and grab it But Su Yu only smiled bitterly. Who would have thought that a random street tavern would ask for such a high price

Su Yu did have ten gold coins on his body, but he had other important things to do today. Therefore, it is a bit difficult.

Seeing that Su Yu's face was embarrassed, the hall owner was furious and sneered: "I don't have the money to be a good man, and I don't want to come to my Agarwood Pavilion." Lao Tzu is gracious today, leave one leg, get out"

Su Yu was shocked and angry, it was just a few glasses of wine, ten gold coins, and any stall on the earth was better than yours. Leave one leg, hum, so ruthless, so domineering. Originally, Su Yu wanted to try to repay the wine money, but now when he heard the innkeeper's words, he immediately became angry: I have eaten this overlord meal today

Su Yu's face sank instantly, his eyes stared at the pavilion owner, and he said coldly: "How do you know, I don't have any money" At the same time, he put his hand into his arms, as if he wanted to withdraw money. …,

The owner of the pavilion was stunned when he heard this, but he lost his mind for a moment. In the moment, ten coins burst through the air, whistled sharply, and went straight to the door in front of him.

The two were so close, Su Yu was raiding again, the hall owner was in a hurry, he didn't have time to think about it, his body suddenly stiffened, and he suddenly leaned back into the sky, and ten coins swept past his face, nailed into the table, buzzing and trembling.

As soon as Su Yu's coin came out, his feet suddenly exerted force, and he immediately jumped upside down, smashed through the window, and fell into the crowd on the street. In the air, Su Yu's figure was already blurred. The moment he landed, Su Yu's body twisted like a fish, quickly shuttling through the crowd, and at the same time changing his appearance again and again, disappearing into the vast crowd.

There was a commotion in the crowd, and no one could figure out what was going on.

The hall owner leaned back, his feet were still firmly nailed to the ground, and when the coins flashed, his figure suddenly rose, looking out the window, but there was still Su Yu's shadow. When I looked back, there were no more than ten copper coins embedded in the table

One gold coin equals ten silver coins. One silver coin is equal to 1,000 copper coins

The guests in the hall looked at the face of the hall owner Tie Qing, and everyone was silent and did not say a word

Opposite the Agarwood Pavilion, there is a blacksmith shop, different from other fancy shops, the name of this shop is three words: blacksmith shop.

And what attracted Su Yu's attention was indeed that there was a long queue of people in front of the door of this blacksmith shop. Looking at the scene, this blacksmith shop seems to be quite extraordinary. Su Yu groaned for a while, and then walked to the end of the team.

Little by little, the team moved forward, and people kept coming out of it. The facial expressions of these people are varied and varied. Some are elated, their eyebrows fluttering; Some are depressed and unwilling; Some of them have expressionless faces, no sorrow or joy. The more Su Yu looked at it, the more strange it became, could it be that there was another secret in this blacksmith shop?

When it was Su Yu's turn, most of the day had passed, and Su Yu walked into the house, and the door slammed shut. There was only one shirtless man in the room, with knotted muscles and a tall body, looking at Su Yu coldly.

Su Yu's gaze patrolled and landed on a piece of matter in front of the big man. Dahan smiled coldly: "You have good eyesight, and you have set your eyes on my piece of dark iron essence when you came up, but so many people outside have not taken him, do you know the art of casting better than these people?" ”

Su Yu looked up in amazement, this big man didn't ask if you were richer than these people, but asked if you knew how to cast better than these people? Did you go to the wrong place, here is to recruit blacksmiths? But what does it mean to take away that Darkiron Essence?

Seeing Su Yu's distraction, Dahan was stunned, and even more angry: "It turned out to be a guy who didn't know the rules, get out immediately"

Su Yu was deflated twice today, once in the Agarwood Pavilion and once in this blacksmith shop, and finally began to have a trace of dissatisfaction in his heart: he had never seen anyone doing this kind of business, and with this attitude, if he had been on the earth, he would have been yellow a long time ago

changed to the fat sea, but I was afraid that I would immediately jump like thunder, and my fists would fall like raindrops. "What, want to do it?" The blacksmith squinted and stared coldly at Su Yu, a cloud of white light appeared in his hand

Bai Guang, the blacksmith, turned out to be a silver master Su Yu took a deep breath, and suddenly felt that this world was really ridiculous, how noble is a silver master, the official above the temple is a general, and the king who occupies the mountain in the mountains and wilderness is actually striking iron here?

"Wait, this master, when you first come to your land, you don't know the rules, and if you are offended, please ask Haihan. But I'm here to order weapons today, and I will pay what kind of price for what kind of quality, and I won't let the master suffer."

The coldness in Dahan's eyes was even stronger, and he said in a deep voice: "It's very simple, if you want a weapon, you must first talk about the way of casting, I have permission, and you can talk about business next." Otherwise, it will be scattered."

Su Yu was stunned when he heard this, and immediately realized that this person was actually taking the opportunity of casting to study the art of casting. Cultivating for a high level and being so obsessed with casting, coupled with the people queuing in front of the door, the big man in front of him is only afraid that he has a lot of attainments in building weapons. …,

If you want to talk about anything else, Su Yu is only afraid that he will hesitate a little, but when it comes to casting, coming from a highly civilized scientific and technological society, how can Su Yu show weakness. Such a good opportunity, such a master, not taking advantage of the last one, I can't bear to be able to cross this adventure

Su Yu smiled coldly, and suddenly did it with a big grin, and did not answer, and began to look at the weapons on the shelves around him. The quality of these weapons, the casting process, and the quality has reached a very high level. However, due to the limitations of the big era, there are always some flaws.

Dahan looked at Su Yu's actions and didn't speak, but a cold light flashed in his eyes. It seems that if what Su Yu said can't satisfy him, I'm afraid it will be very bad

"Are your weapons rusty?" Su Yu asked lazily, completely ignoring his dangerous situation.

"What do you say?" The blacksmith's voice was colder.

"What if it's in a humid environment?" Su Yu's voice was lazy and weak.

The big man was suddenly furious, and the temperature around him rose sharply. Iron can rust, something that even three-year-olds know, not to mention in a humid environment. The kid in front of him asked such an idiotic thing. I still hope that this guy can say what kind of casting technique

"Get out of here, or I'll help you" The blacksmith was furious, uncontrollable, and his voice was so cold that it would freeze into ice

"What if I had a way to keep the iron from rusting?" Su Yu's voice was as lazy as ever, but it was like thunder in the blacksmith's ears.

"What?" Dahan was stunned for a moment, and then laughed angrily, "Needless to say, the paint on the weapon is needless to say, if it is the essence of the extraterrestrial meteorite or the essence of the dark iron, it is needless to say that it is good to get out directly." ”

"Ordinary iron, I also look at it to make it rust-proof and corrosion-proof" Su Yu stared at the big man, his eyes shot a fine light, "But what do you exchange for such a casting magic technique?" What do you have to exchange? ”

The blacksmith was stunned when he heard this, yes, this kind of casting technique, it is not too much to say that it is a magic technique, he is from a blacksmith family, and he knows the value of this technology. What can be exchanged for this kind of casting in the world? It is necessary to know that ordinary military equipment, placed in the armory, a large number of weapons will rust and break every year. Over the years, replenishment of weapons has been a major part of military spending. If you can forge a stainless weapon, what is this concept?

This blacksmith is obsessed with casting, and naturally regards casting as more important than anything else, and this kind of casting technique has become more important than the country in his eyes.

"Does this technology really exist?" The blacksmith suddenly raised his head, his face suspicious, this kid didn't come to scare himself, "With this kind of casting technique, why did you come to me"

"Stainless steel technology only, I just ask you what to exchange?" Su Yu stared at the blacksmith closely.

"What do you want?" The blacksmith asked rhetorically.

"I want the best casting materials and the best weapons for you here"

The blacksmith looked at Su Yu, but showed hesitation, and seemed to be undecided. Su Yu was shocked: With his understanding, using stainless steel technology to exchange this material and weapon, the other party should have a feeling of taking advantage of it, is it wrong that this old boy is only Ye Gong's good dragon for the casting technique, and he has nothing to show for it?

"Can you ask for a different one?" Dahan was embarrassed and said softly.

Su Yu's eyes lit up, could it be that this blacksmith shop really has a treasure?

"No, I've also walked a few blacksmith shops in Sunset City, and you're still a knowledgeable person. As a senior blacksmith, you should understand the importance of this stainless steel technology, such an epoch-making technology, in exchange for a material, a weapon, is it difficult to wronged you? Alas, it is actually difficult to live up to the fame" Su Yu stood up, with a look of disdain in his eyes, there was a lot of meaning here and there.

The blacksmith suddenly showed a painful look in his flesh, gritted his teeth and said: "Deal, if you can't tell why, don't walk out of this door today"

Su Yu smiled slightly, as if he didn't hear the threat in the blacksmith's tone. He said softly: "The reason why ordinary iron rusts is related to its own properties is related to its own properties, and it is related to air and water. Therefore, the anti-rust is to coat the surface of the iron with a protective layer, but this is only a symptom but not a cure. The most fundamental solution is to mix other materials during smelting to change the properties of iron, so that the iron is smelted. Anti-rust, anti-corrosion, lighter, harder and even have all kinds of indescribable benefits......"

The eyes of the big man became more and more bright, listening attentively, relishing and admiring from time to time, and even asking a sentence or two, the tone changed from the rude and impatient at the beginning, to be polite and polite

"Can you elaborate on the doping ratio of these materials you are talking about?" The blacksmith looked at Su Yu's gaze, eager and longing, as if he had seen a giant panda, a national treasure.

"Sure, but before we talk about that, should we take a look at the materials and weapons?" Su Yu smiled slightly.

"Ah, yes, of course please wait" The blacksmith nodded repeatedly, turned and walked upstairs, and after a long day of tinkering, he walked down. Holding two boxes in his hand, his expression was extremely solemn......
