A few minutes later, most of the ninth class of the academy under the leadership of Mu Hibiscus came to a gray building, which had been in existence for some years, and in addition to the masonry, there were a lot of metal structures on this building, which reflected a harsh light in the sunlight.

"Boom, bang~"

There was a roar from inside from time to time, and you could feel the shaking of the ground when you stood outside, and there was a metal plate next to it that read—Soul Guide Test Area.

Su Xiu and the army followed behind Mu Hibiscus and walked towards the building, entering a long corridor with several doors on both sides, on which were written signboards for No. 1 and No. 2 in the experimental area, and the distance between each door was about thirty meters.

Su Xiu and the others walked all the way to the twelfth door, Mu Hibiscus turned over and took out a hexagonal silver token, pressed it on the gap in the door, there was a sound of mechanical operation, the door cracked to both sides, and the token was also put away by Mu Hibiscus.

Walking into the room, it was a very open field, larger than a football field, and the height was up to ten meters high, which seemed very vast, and there were two strong men in it who were experimenting with the soul guide cannon, and part of the roar just now was caused by them.

Chen Ze looked back, the heavy mechanism door had already been closed, and if he wanted to use brute force to destroy the two-foot-thick mechanical iron door, there was basically no play below the Soul King, even if it was above the Soul King, it could not be solved in one or two clicks.

"Sail Feather."

Mu Hibiscus summoned softly, only to see a relatively older man walking towards Su Xiu, more than one meter eight tall, a head taller than Su Xiu, the key is the thick body, strong arms, short-sleeved shirt is full, and the strength of this strong man is also felt from the outline of the shirt.

"Why are you here?" Different from Zhou Yi's mean and bitter attitude towards Hibiscus, Fan Yu's tone of voice to Hibiscus was very gentle.

"Why, can't I come if it's okay? Vice President of Fan Yu! Mu Hibiscus asked rhetorically, looking at Fan Yu's eyes revealing inexplicable emotions, which were regrets, expectations, and love......

"Of course you can, you are also a soul master, so you naturally have the right to come to the soul guide system." Fan Yu took a step back and looked at the group of students following behind Mu Hibiscus, "In that case, you should be busy first, I still have some soul guide parts to make here!" ”

Fan Yu doesn't treat hibiscus like Zhou Yi, but he himself doesn't have a cold, he just treats her as a colleague, after all, he already has Zhou Yi, so naturally he won't have anything to do with other women!

Seeing that Fan Yu was gradually moving away, Mu Hibiscus stomped his feet angrily, gritted his teeth and said, "What are you still standing there doing, come around, today we will learn the first lesson of making a soul guide - striking iron!" ”

Blame her, she fell in love with someone she shouldn't like.

Fan Yu obviously already has Zhou Yi, but Mu Hibiscus is reluctant to fall in love with him, and is still expecting him to empathize with him, so he has been waiting.

Hibiscus waited, waited, and waited for an older leftover girl.

The older she gets, the more anxious she becomes, her youth is gone, the more she wants to behave better than Zhou Yi in front of Fan Yu, and her main thing is nothing more than being jealous of Zhou Yi.

But she was wrong, no matter how she behaved, Fan Yu was still the same Fan Yu, even if she defeated Zhou Yi, things would still not change.

As the so-called Qing official is difficult to decide family affairs, let alone he is an outsider, Su Xiu shook his head and dispersed his thoughts, no matter how the three of them want to develop, it has nothing to do with him, let's beat the iron first.

Before coming to the forging table, Hibiscus first took out a few pieces of iron ore, and then sorted the rest of the materials on the workbench.

After all the preparations were made, Mu Hibiscus was surrounded by a group of students and ready to start the iron work.

"Let's get started!" Mu Hibiscus came back to his senses, glanced at the materials in front of him, and introduced to everyone: "Forging soul guide parts, there are five steps in total, I will only say it once, you have to memorize it by heart......

Everyone nodded heavily and looked at Hibiscus with serious expressions.

"The first step, hammering, is to melt the ore in a furnace and make a rough blank through a carburizing process, which is repeated many times, depending on the material being made.

The second step, planing file: use a steel knife to sharpen the file, so that the material is roughly close to the finished product, and the parts are paired with parts in a certain batch.

The third step, polishing: the parts of the file are polished on the stone, rubbed evenly with a gold steel sand cloth inlaid with an iron ruler, first coarsely ground with a coarse sand cloth, and then finely ground with a fine sand cloth, and the polishing work is twice as good as that of hammering and planing.

The fourth step, quenching: using the traditional quenching method, after "strong forging", use a special quenching agent for "softening" treatment, so that the body of the device itself is rigid and soft, and can be bent and stretched.

As for the last step of inlay, it is not necessary: after the soul guide is formed, the pattern, name or the word of the customizer is engraved with steel needle money, and the red copper is inlaid, and then after special treatment, the blue light sword body is golden, producing color contrast, indicating that it leaves the factory.

These five steps sound simple, but in practice, they are very difficult...... And today we're going to make the simplest one - a sword! ”

"Stretching and stretching a piece of iron ore after thousands of hammers and then shaping it into a sword shape is the simplest but also the most time-consuming!"

After saying that, Hibiscus picked up the prepared ore and threw it into the furnace, "The temperature is not enough, turn on the fan to the maximum!" ”

"Okay, teacher!" One of the assigned students became the royal fireman.

As the minutes passed, I saw the ore in the furnace melt little by little, and finally turned into red molten iron.

Hibiscus picks up tongs and introduces the molten iron into the mold, and soon, the molten iron solidifies, forming a sword embryo.

"Look, this hammer is not a blind beating, but requires skill...... "After speaking, the hammer in his hand fell.

While!

The hammer slammed into the sword embryo, and then, as the hammer rebounded, Hibiscus turned around quickly, and the hammer in his hand was picked up again, and there was another loud bang, and the hammer fell heavier than before on the red-hot sword embryo.

While!

With the help of the rebound force of the impact, the third hammer was already picked up again, and this time, the casting hammer was castrated more urgently, bringing a whining sound.

While!

There was another loud bang, and the heavy casting hammer seemed to come alive in the hands of the hibiscus, and circle after circle was drawn in the air, full of rhythm, like the sound of a violent storm.

With the clanging sound, the red-hot sword embryo kept beating under the casting hammer, and each loud bang was like a thunderbolt, roaring in the forger's ears.

While!

While!

While!

……

"The point of striking iron is the relay, and it's all skillful to see how my arm moves and the angle at which the hammer hits...... Hibiscus said.

Hammer after hammer, and, one hammer heavier than the other.

This kind of thrashing technique is unheard of and unseen, like a divine skill.

The students who were brought over by Hibiscus to visit the Soul Guide Department widened their eyes one by one, afraid that they had missed a certain detail, and observed carefully, their eyes full of shock and admiration.

"Awesome, the teacher is so amazing......"

Many people are extremely shocked in their hearts, if they can learn this trick to become a soul master, they will have no regrets in this life!

Su Xiu looked intently, the divine light in his eyes flowed, and the action of the hibiscus when he cast the sword was slowed down, and little by little the details were received.

In Su Xiu's view, the forging process is roughly the process of force, using a hammer to enrich the iron ore with a force, and then applying the force returned back in the forging process to the ore again, so that it can stretch and deform according to the idea of hibiscus.

When!

After the last blow was completed, Hibiscus took the casting hammer and spun around twice in a row, dissolving the momentum on the hammer, and the sledgehammer hammered its head downward and fell back to the ground, which made the hearts of the surrounding students shake at the same time.

Eighty-one hammers, the full eighty-one hammers continued to strike, making the entire sword embryo shrink by half as a whole, which means that there are fewer and fewer impurities inside.

The students couldn't understand the mystery, but it didn't prevent them from shining brightly, and they wished that it was they who forged it.

"Okay, this is the mystery of striking iron, today's lesson is here, you go back and digest it first, anyone who understands what they have learned can come to me in advance, and I will teach it myself!"

"In addition, in the future, you will have an hour after school every afternoon to come here with me to learn iron, of course, if there is a teacher who is unwilling, he will not force it, after all, you have never studied for me!"

"Got it, teacher!" Everyone responded in unison, and then followed Hibiscus out of the soul guide test area.

Su Xiu, who followed the large army, looked at the hibiscus who led the team in front of him, and he also gained a lot, the casting method of the outer sword is very different from what the hibiscus told today, but there is one more step to endow the spirit, only by endowing the outer sword with the spirit, can the outer sword and the inner sword finally merge into one and become the monk's natal flying sword.

However, today's personal demonstration of Hibiscus has given Su Xiu a lot of experience, and he must be able to try to forge a sword by himself tomorrow.

"Wait, Su Xiu, come with me to the office!"

After saying this, Hibiscus glanced back at the building behind her again, if she wants to win, she must win against Zhou Yi, a bitter and mean old woman, so that Fan Yu will look directly at her and no longer regard her as nothing!
