My Soul card is a Reaper

As they looked at their teacher in a mix of disbelief and confusion, Azzy couldn't help but sigh inwardly because of how pathetic they appeared right now. 

For an intelligent guy like him, it is something obvious, not rocket science. Not to mention, the students of this class had great scores in theoretical combat too.

Hence, he couldn't help but be slightly disappointed as they didn't live up to his expectations.

Throwing the useless thoughts away, Azzy pointed the marker at the short-haired girl in the front row, "Student Talia, what do you think will happen if one adds the lightning energy from an elemental crystal to a fireball? Note that I have a decent amount of mastery over energy control."

Talia grabbed her chin and thought for a bit and answered, "Sir, Fire, and lightning attributes are incompatible. They cannot be merged. So, they will fight for supremacy. Considering the lightning energy from crystals is weaker, then, it should get pushed away. However, with decent control, we could probably make it stay on the surface of the fireball."

Azzy nodded with a smile, "that's correct. Now, what if I throw that attack at the enemy? What will my opponent faces first? The heat of the flames or the shock of the lightning sparks?"

"The lightning sparks cuz it was on the surface of the fireball," replied Talia before imagining the scenario. Her eyes widened as she continued, "The enemy will first paralyze by the shock before he receives the flames. The lightning here acted as the armor for the fireball."

"Exactly." Azzy gestured for her to sit down and turned toward the whiteboard. "Imagine. What if I enhance the fireball with wind energy and then apply the lightning energy over it?

Next is its relation with the Earth attribute. Unlike the other attributes, earth energy usually turns solid after a certain amount of time. 

Rather than applying it to the fireball, the fire attribute users would have to use fire energy over the condensed form of earth energy, which is nothing but a stone.

However, if we do that, the fire will just melt the rock, provided that it is hot enough. Fortunately, at your level, you cannot create flames with such high temperatures. 

So, you don't need others' help. Create a stone from earth elemental crystal and use fire over it. Increase the flames with the wind. And then, coat the bigger flames with lightning. This is the type of combo attack the fire attribute users should be aiming for.

But, if you had a teammate, you can combine your soul skills. Your attack damage will only increase further. Of course, practice will be necessary and there's no shortcut to achieving it."

As the students nodded, the blonde-haired boy raised his hand and asked, "But Sir, elemental crystals are quite expensive if we had to buy numerous amounts, and acquiring them from the wild zone is quite risky."

Looking at the class monitor, Azzy spoke, "Who said you needed to buy or acquire elemental crystals? You can just create them."

"What?"

Azzy's reply once again unleashed waves of shock in the classroom.

"Create them? Are you kidding?" A student named Shaun couldn't control his pitch and almost screamed because what he heard can only be termed as an absurd thing.

In response, Azzy summoned his storage card and took out an empty blank card made of bronze. "I don't mean it literally. It is impossible to create elemental crystals as they are grown in the soil. Based on the habitat and the monsters roaming around in a place, they were decided. However, it is nothing more than converting natural energy into elemental energy. The crystals are just medium.

But, if I do this…"

While explaining, he raised his hand. The natural energy in the surroundings rushed toward him. However, he didn't absorb it.

Instead, he gathered it above his palm and compressed it into the form of a tiny sphere. "First, we insert natural energy like this…"

He sent the natural energy into the blank skill card where people usually send their soul energy to create skill cards and become card masters.

As the natural energy was trapped in the blank card, he didn't shape it with any imagination. He then raised his hand once again, gathering the lightning energy. Soon, black lightning sparks appeared over his palm.

Because of the fact that he unleashed a laughing skull of darkness technique and then a meteor shower against Snivy, they believed that it is his attribute is dark and earth.

But seeing the lightning sparks changed their opinion. Some assumed that either their teacher has three attributes or the meteor shower is just a skill card he purchased somewhere. 

As for the dark attribute, they had no doubts about it due to Azzy's behavior toward 10-A students and the black color of the lightning sparks.

Meanwhile, the black lightning energy was also inserted into the skill card. The natural energy, upon contact with the black lightning sparks, reacted wildly.

For a moment, it appeared as if the skill card will explore but Azzy skillfully merged the both of them. As a result, the lightning energy became independent of its original recipient.

Raising the card, Azzy then said, "Pure attribute energy + natural energy will give you the elemental energy, the same energy present in elemental crystals. I can teach the method of manipulating natural energy during our practical combat lessons, but for that, you would have to reach the stage where you can extract attribute energy from your soul orbs like it is nothing. 

Unfortunately, I can't teach you how to do the extraction in a natural way because this talent is something I was born with it."

Everyone: "…"

The ray of hope they saw turned out to be a mirage as no one was confident enough to pull it off. Using attribute energy is a stuff of legends for them. 

The fact that they get to witness such an amazing thing in the class had already become something memorable.

In such a case, does anyone think they had a chance?

Julius could only bitterly smile in response to Azzy's condition, "Sir, it is impossible for the people of this generation."

One of the reasons Azzy liked these students is also because they knew their strengths and weaknesses quite well.

Azzy shook his head, "don't admit defeat so easily. I told you guys that I can't teach you how to do it in a natural way. I didn't say that I don't have any ideas. The process is actually very simple to learn but hard to master.

The easiest way is to unleash the soul skills and then extract all of your soul energy present in it. The remaining attribute energy could be trapped within a skill card. 

But, since soul skills have a cooldown timer, it is best if you can unleash soul energy attacks that contain attribute energy. That way, we can separate both of them after sealing the attack."

The students of 10-B couldn't help but just look at each other in a mixture of bewilderment and confusion. The stuff Azzy was explaining to them was way above their knowledge and talent. They couldn't even understand half of it.

How could they do it? But, if they could, then, it is awesome.

In the end, all these students could do is just nod and go with the flow.

Azzy wasn't also too eager to teach the technique he learned from the guardian god during the past three years. He was just speaking of the theory. 

However, if there's really someone talented enough to do that, he will be willing to teach him. After all, extracting attribute energy isn't something related to soul power or Arcana. Gideon did it and even might have taken it to the next level by now. So, why can't others?

"Anyways, we are getting sidetracked. Let's get back to the original topic. We finished the fire attribute. Next, for the water attribute users.

Water is strong against fire. Even when fire overwhelms the water, it doesn't disappear. It would just transform into water vapor. Hence, if you have enough mastery over your attribute, you could control the water vapor before it leaves your range.

Of course, when we talk about water, we often talk about how lightning is its natural ally. Many textbooks say that too. But, you should also remember that pure water is a bad conductor of electricity. Those with water attributes should note this point.

That means, if you could unleash the attribute energy of water without any mixture of your soul energy, you would be able to block lightning attribute-based attacks. 

You might not be able to save yourself from receiving damage but you will save yourself from receiving electrical shocks or getting paralyzed."
