It was late when I got back to the dorm.

Because it is a key class in the inner courtyard, there is an independent dormitory, and although the dormitory is not large, although the sparrow is small, it has all kinds of organs, bedrooms, kitchens, and bathrooms.

After Mu Yi took a bath, he took out the black iron sword tire from the storage space and began to engrave the formation pattern.

Now Mu Yi has only forged a black iron sword fetus, and if he wants to completely turn the black iron sword into a magic weapon, he must engrave it into the runes.

It's like a computer on Earth, a computer is divided into hardware and software. The principle of the Dharma instrument is the same as that of a computer, which is divided into hardware and software, both of which are indispensable.

Mu Yi sat cross-legged on the bed and took a deep breath.

I saw Mu Yi stretch out his right index finger and slash towards the void, and suddenly the runes in the void condensed with the wave of his fingers.

These runes stood in the void and shimmered with dazzling golden light, looking extremely mysterious. Runes are the foundation of the formation pattern in the cultivation realm, and any formation pattern in the cultivation realm is composed of thousands of runes.

And each formation pattern is a kind of supernatural power, the same as the formation map of this world.

One by one, the runes danced with Mu Yi's hand, and there were more and more runes, and these small runes began to combine under the control of Mu Yi's divine sense, one rune was simple, but a combination formed a complex pattern.

And these intricate patterns are formations.

As soon as the formation pattern was formed, it fell into the black iron sword.

Suddenly, the black iron sword, which was already shining brightly, was golden and generous, and complex runes loomed on the body of the black iron sword.

But that's just the beginning. Mu Yi's hands flew over, more runes formed, and more formations were formed at the same time.

These formations are regularly submerged into the black iron sword, which makes the formations inside the black iron sword more and more complicated, and the golden light of the black iron sword's sword body is even better, which actually makes the black iron sword illuminate the bedroom like a small sun.

And just like that, two days later.

In the room, Mu Yi sat cross-legged on the bed, and a black iron sword in his arms looked ordinary like an ordinary black iron sword, but if you looked closely, you would find that the black iron sword was faintly covered with complex patterns.

Mu Yi sat on the bed with a pale face.

His soul was already injured, and burning the formation pattern required the use of divine sense, so now Mu Yi's divine sense was greatly damaged, and it was a great luck that he did not pass out.

"Fortunately, the magic weapon is done!"

Mu Yi rested for another hour, and only after his divine consciousness had recovered a little before he opened his eyes and looked at the black iron sword in his hand.

Mu Yi smiled slightly, and suddenly the black iron sword in his hand flew with golden light, and then circled and rotated around Mu Yi. The black iron sword became larger and smaller at one time, and finally became the size of a hairpin, and was inserted into a bun coiled up on his head.

Since Mu Yi still liked the dress of the Taoist priest in the previous life, his head shape also maintained the head shape of the Taoist priest, and a bun was tied at the back of his head.

"Big brother is gone!"

At this time, the sky was also bright, and the voices of Tang San and Xiao Wu sounded at the door.

"Haha!"

Mu Yi laughed, got up and opened the door.

"Let's go, let's go! You can't be late for class today. Xiao Wu was eating something in his mouth, and he didn't forget to urge Mu Yi and Tang San.

Mu Yi smiled and closed the door, and walked out of the dormitory area with the two of them towards the teaching building.

The key class teaching building and the outer courtyard teaching building are not in the same place, but are separated. These days, the three of them have long been familiar with the teaching building of the inner courtyard, and the three of them walked towards the fighting arena.

They have been informed that they are going to have classes in the academy arena today.

The three of them came to a large circular building, which they had been here for a long time, but had not yet entered.

Walking into the huge circular building, it suddenly opens up in front of you.

In front of Mu Yi was a huge space similar to an indoor basketball court in Mu Yi's previous life, and there were countless seats on all sides of the room, but in the center was a huge open space.

And at this moment, a fierce fighting sound was coming from the center of the clearing.

I saw two burly teenagers fighting fiercely in the middle of the clearing.

The two teenagers did not use weapons, but they wore weapons like metal claws. The two of them are very fast, and their moves are extremely ruthless, and every time the two collide, they will make a metal crashing sound.

"Their speed is beautiful!" Tang San was also watching the two fight, and let out an exclamation.

Although there is no martial arts in this world, the art of fighting and killing is exactly the same as the external skills of martial arts, and there are many masters among them.

At least now these two teenagers were the most powerful two Tang San had ever seen.

"Soul Master Level 18!"

Mu Yi was also attracted by these two teenagers, and his divine sense swept over the two of them and found that their cultivation had reached level eighteen. These are the two soul masters with the highest cultivation that Mu Yi has ever seen in the Soul Master Academy.

"Oops, they... They won't... It is... It's black and white! ”

"No, they are black and white, and the two of them are ranked first and second among the disciples of the inner courtyard of my academy!"

"I've also heard that these two are brothers. The eldest brother Hu Hong, the second brother Hu Fa"

"Yes, they are all brothers. Awesome! This is our captain! ”

The people who came to the fighting arena were not only Mu Yi and others, but also the academy that entered the key class with Mu Yi and others that day, and some strange teenagers that Mu Yi had never seen, they also watched the two teenagers fight with wide eyes.

The students present were even more discussed, and told the information of the two.

"Haha, they're all level eighteen now! As long as you break through to level nineteen, you can get a soul ring and become a great soul master! You can go to the Advanced Soul Master Academy! ”

The old students of the key class proudly introduced the two teenagers to the new students of the key class this year.

The key class is different from the ordinary, the key class only enrolls ten people every year, and the new and old students are all in the same class, and will not be held separately.

After all, at the level of the soul master, there are very few cultural classes, and most of them are actual combat classes.

Just when everyone was watching Hu Hong and Hu Fa fight fiercely, suddenly Hu Hong and Hu Fa suddenly ran towards the door.

One of them ran away and the other chased after him, and the two chased and fled, and the fight was very exciting.

After just a few breathing exercises, the two of them had already come to a distance of only a few meters from Mu Yi.

'Bumper...'

The half-meter-long metal claws worn by the two of them flashed with cold light, and each impact made a piercing sound.

At the door, everyone was even more shocked when they saw this, and the two fought fiercely, where had everyone seen it, and everyone was even more frightened and retreated, not daring to approach the two of them.

Compared to everyone else, Mu Yi, Tang San, and Xiao Wu stood in place indifferently, watching the two fight.

"Hmph, it's this little bastard, dare to kill my evil wolf gang blood wolf guard, I don't know whether to live or die, let me try how many catties and taels you have." Of the two people in the fight, one of the elder brothers, Hu Hong, glanced at Mu Yi and thought viciously in his heart.

Hu Hong's eyes flashed with coldness, the corners of his mouth turned up slightly, revealing a sarcastic look, and then gave his younger brother Hu Jackal a look with great meaning.

When the younger brother saw his elder brother Hu Hong's eyes, the corners of his mouth curled up, and he also showed a sarcastic look.
