Douluo: Become invincible from saving Jiang Nannan

The next day, early in the morning.

What surprised Lin Heiyu was that the first-grade teaching building that was half destroyed by his Mercury punch had been repaired, and the huge hole he made was blocked by high copper and iron walls.

"The operation efficiency of the Sun and Moon Royal Soul Engineer Academy is so high." Lin Heiyu clicked his tongue in surprise.

When they arrived at the cafeteria, the students at Shrek Academy felt the gap.

The cafeteria of the Sun and Moon Royal Soul Engineer Academy does not have as many delicacies as Shrek Academy, but only ordinary meals.

It would be enough if it was just a simple meal, but it was far less nutritionally balanced than the canteen of Shrek Academy.

After everyone finished breakfast, they returned to the dormitory. Two school uniforms that had been processed overnight had been delivered.

The teacher who delivered the school uniforms informed everyone to gather in the sixth grade teaching building. The sixth grade teaching building was very large, but there were only a few dozen sixth graders in the entire Sun Moon Royal Soul Master Academy. Every time you advance to a grade, more than half of the students will be eliminated in the promotion assessment, and the elimination rate is very high.

The teaching director Lin Jiayi was waiting in advance, and there were ten teachers behind Lin Jiayi.

"Everyone, classmates, behind me are sixth-grade teachers, at least seventh-level soul masters. Each of them only teaches a few students. In order to show fairness, the teacher will choose one of you by drawing lots. Teachers choose one," Lin Jiayi said.

Lin Heiyu raised his hand and said, "Director Lin, can I come with Huo Yuyan? She and I are brothers and sisters of the same sect."

When Lin Jiayi saw that it was Lin Baiyu, a first-level soul master, he thought it didn't matter. Teaching a first-level soul master was really troublesome anyway, because sixth-grade teachers didn't bother to explain such simple knowledge. If Huo Yuyan is allowed to learn and then assist Lin Baiyu, the effect will most likely be better.

Lin Jiayi nodded slightly and said, "Lin Baiyu, whichever teacher draws Huo Yuyan, you can study with that teacher."

Lin Heiyu, a drunkard, didn't want to drink. He didn't want to learn about soul tools, but to meet oranges.

Ten teachers drew the folded slips of paper one after another. A teacher in his thirties picked Huo Yuyan. He said expressionlessly: "Huo Yuyan."

Huo Yuyan walked out quickly and said, "Hello, teacher."

Lin Heiyu followed closely behind.

"Hello teacher."

The young teacher glanced at Huo Yuyan and Lin Heiyu and said, "Follow me."

Huo Yuyan frowned. She felt that the teacher seemed very impatient.

The key is that this teacher is too young, having become a seventh-level soul engineer in his thirties. To achieve such a high level of achievement at such an age, he must have spent all his energy and time on researching soul guidance devices, forgetting sleep and food.

Huo Yuyan was worried that the teacher's teaching ability might not be good.

The young teacher took Lin Heiyu and Huo Yuyan to the second teaching building of the sixth grade, reached the fifth floor, and walked to the third laboratory.

The young teacher took out an identity plate and waved it in front of the door.

"Bip! Special teacher card!"

The metal door slid silently to both sides and opened.

This laboratory is very large and filled with various soul tools and metal materials. A silver-white metal experimental table is clean and tidy.

The young teacher said calmly: "My name is Xuan Ziwen. I don't care what the rating standards of your Soul Guidance Department of Shrek Academy are. As long as you can't pass my test, you two can go to the library to study on your own. Don't waste my time."

When Lin Heiyu heard this, he was stunned.

Lin Heiyu didn't understand soul guidance devices at all, so there was no way he could pass the test.

Not to mention the test of the soul guidance system, Lin Heiyu only knew a little about many things about the martial soul system. He could even fail the test paper of the martial soul system.

Huo Yuyan said: "Teacher, you are so irresponsible."

Xuan Ziwen said lightly: "Originally, I didn't want to take this job. If you are not convinced, you can go to the dean to protest. I will give you two a quarter of an hour. You can choose the materials as you like. Huo Yuyan, you are a third-level soul. Instructor, you have a quarter of an hour to create a core array for a level 3 soul tool that you think is the best. Lin Baiyu, you are only a level 1 soul advisor. You need to create a core array for a level 1 soul tool that is your highest level. Can."

After saying that, Xuan Ziwen started a soul guide timer countdown, which was fifteen minutes.

Lin Heiyu could only stare. He knew nothing about soul guidance devices. How could he possibly make the core magic circle?

But Huo Yuyan is completely different. She is a truly top-notch talented soul mentor.

She walked to a pile of metal materials, turned on her mental detection, raised her right hand, and the dark gold terror claw popped out, cutting out a piece of bright silver metal. Use Controlling Crane and Capturing Dragon to grab the metal.

Putting away the dark gold fear claws, Huo Yuyan used the claws of the Ice Emperor. Her hands became like diamond ice crystals. She held her hands and rubbed the bright silver metal directly with her hands.

Xuan Ziwen was immediately shocked. This piece of metal was titanium, which was extremely hard and was a specialty metal of the Sun and Moon Empire.

Xuan Ziwen clearly saw that Huo Yuyan cut a piece of titanium almost silently with a wave of her hand.

Just when Xuan Ziwen was calculating the sharpness of Huo Yuyan's dark gold terror claws, Huo Yuyan's palms were like ice, directly grinding the titanium gold, and fine silver-white powder continued to fall from between Huo Yuyan's palms.

The next moment, a silver-white lychee-sized ball appeared on the table.

Huo Yuyan used an ordinary carving knife. She held the metal ball in her left hand and the knife in her right hand, and quickly carved on the metal ball. Beautiful lines quickly appeared on the surface of the metal ball.

Xuan Ziwen frowned and said: "One charging array and six accelerating arrays will be scrapped after one use. It is simply too extravagant and wasteful."

Huo Yuyan ignored Xuan Ziwen. She carved the metal ball very quickly without making any mistakes.

In five minutes, Huo Yuyan completed the carving of the core array.

At ten minutes, Huo Yuyan blew gently to blow off the debris on the surface of the metal ball.

The metal ball made of titanium has been hollowed out and has mysterious textures.

Huo Yuyan held the metal ball of the core array in her hand. She said neither humble nor overbearing: "Teacher Xuan, I have finished it."

Xuan Ziwen said coldly: "It's a show-off, fancy and of no practical use."

Lin Heiyu on the side scratched his head and scratched his head. He saw that he was the lowest level soul master who had not even started.

Xuan Ziwen looked at Lin Heiyu and said with a cold face: "Lin Baiyu, be more conscious and go to the library by yourself. You are not suitable for learning soul tools."

Huo Yuyan said: "Wait a minute. Teacher Xuan, there is still some time. I hope you can give me a chance to complete the production of this soul guide. If the finished product does not satisfy you, my senior brother and I will take the initiative to Library, I won’t bother you anymore.”

Xuan Ziwen was already wasting time today, and he didn't care if he wasted a little longer.

"Okay, I'll give you this opportunity to see what other tricks you have up your sleeve." Xuan Ziwen said lightly.

Huo Yuyan chose the most common material, metal, iron essence.

The Dark Gold Terror Claw appeared again and cut off the Iron Spirit.

Soon, Huo Yuyan carved the iron essence into the shape she wanted.

The arrow-shaped metal bars are constantly blending in, making a clanging sound.

Clang clang clang!

A long box about one foot long, three inches wide and two inches thick appeared.

Xuan Ziwen said: "Is it done? Try your power and let me see how amazing your work is and how confident it makes you. If I'm not satisfied, you and Lin Baiyu can go to the library and study on your own. Don't bother. I."

Huo Yuyan was very confident and walked to the soul guidance test area.

Huo Yuyan raised the long iron box and pointed it at the alloy wall fifty meters away.

Bang bang bang!

A series of dull explosions sounded, and blackened holes appeared on the alloy wall fifty meters away!

Seeing this scene, Xuan Ziwen's eyes changed: "Level 4 soul guide? The materials are too poor, otherwise it would be able to reach the level of a fifth-level soul guide. Without injecting soul power, you can launch an attack by just turning on the switch."

This is the Zhuge Divine Crossbow. Tang Ya gave Huo Yuyan the drawings and it took her half a year to figure out how to make it.

It's not very powerful, but it can be used by ordinary people, and its limitations are not as great as soul guidance devices.

Soul guides must be used by soul masters and must be infused with soul power.

The more soul power is injected into a soul guide, the higher its power will be, and it has strong limitations.

How to let ordinary people use soul guidance tools, this is a difficulty that the Sun and Moon Royal Soul Engineering Academy has been working hard to overcome!

Xuan Ziwen was very excited, and his eyes were full of excitement: "Huo Yuyan, can you sell this to me? You can set the price as you like, I want to study this."

Huo Yuyan answered the question incorrectly. She said, "Teacher Xuan, did I pass the test?"

"Passed, passed! Sell me this weapon!" Xuan Ziwen said in an urgent tone.
