My Girlfriend is an S-Class Adventurer

The water then turned into a kind of sea serpent, with a transparent light blue color. It was possible to see how the layer of water formed a kind of water scale, along with spines and even teeth in the mouth of that spell. On Erwin's head, a crown of water formed. That crown was spinning on top of his head, following a flow, it seemed to be alive.

On the back of the water wizard was an amazing pair of wings, and several rings of water flowed around the wizard's body. Protecting him as if he were an armor.

"Many speak here in this academy that the strongest field of magic is fire, or maybe air. But controlling the sea gives you powers far more impressive than any other line here. Powers that rival even the broteforge genes" Erwin said.

"Not only am I the Azure Sea Lord, I am also a master of salt" Extending his arms, the mage slapped his hands together, joining both hands.

That snake in seconds completely changed from that transparent appearance, to a white color. It was taking on a solid form, as if the entire surface was slowly connecting. Until finally, that magic, that creature, was completely made of salt.

The magician then snapped out one of his hands, and reached out creating a sword of salt.

Watching Luke from above, Erwin gave a smile and started to laugh. Quickly, the whole thing fell apart, bringing all the water to the ground, as well as the salt that piled up on the sand.

"That's a nice skill, isn't it?" Erwin said, with another laugh.

[This guy seems a little strange to me].

No doubt he's not normal at all.

The mage then crossed both arms and began to look at the horizon, while continuing to chat with Luke. Erwin's face was filled with a giant smile, it was as if he was grateful to have someone to talk to.

"I learned this trick a few weeks ago, well it's not very nice to just show off.

[He only realized this now?]

'I won't deny that the presentation was interesting'

In Erwin's mind, having a visitor on his beach was a moment to demonstrate his skills. Since the mage hardly ever welcomed spectators, at the same time, where he was interested in explaining to Luke how his wave control magic worked, he wanted to demonstrate his powers.

"When you are controlling salt water, you need to understand it as a living organism. In the ocean, anything different can completely ruin the life of a region. That goes for controlling the waves, imagine every movement the sea makes, but not only that, you also need to be

aware of how the salt and other components of the water behave" Erwin went on to explain, turning to Luke.

The mage's eyes were sharp, as if he was interested in the reaction the half-wolf would have to that conversation. For the Azure Sea Lord, this was the moment to realize whether Luke was a skilled mage or not.

The conclusions that the half-wolf would draw would easily define for Erwin whether he was a promising novice or just innocent enough to expose himself to the danger of seeing the tests on his beach.

"That means I should keep an eye on even the fish that are moving around within the area I'm controlling, right? After all, any irregularity could end up influencing the flow of the sea" Luke questioned.

Erwin's eyes widened, and soon after a smile appeared.

In the Azure Mage's head, a shower of thoughts were passing. 'Who is this half-wolf? When did he enter the academy? Is his skill on the same level magic comprehension as his? Should I test him?' All this in a millisecond. As much as his actions and the way Erwin behaved showed that he was a carefree person, the truth was that the way he thought showed the exact opposite.

Luke knew that it was always necessary to be suspicious of someone, so it didn't take long for him to realize with his trained eye how that mage's behavior wasn't just strange by nature.

"Exactly! Hahahaha usually nobody understands that fast. Why don't you try to control the waves a bit?"

"No problem, I still have a bit of free time. It will be interesting to train a little with you. I'm really not very good with water magic.

Erwin's friendly eyes returned to that critical tone, he was watching Luke's decisions.

That sudden change in the wizard's gaze was enough for Luke to realize the truth.

'He is more interesting than I imagined'

[Yes, his behavior is a little strange]

'I'm not sensing any hostility, but no doubt he has a habit of playing dumb.

[It's simpler to deal with people when they diminish you. Not only is his skill amazing but his behavior and planning, he is undoubtedly a dangerous mage]

Balance and Luke had this brief conversation as the half-wolf approached the sandy beach. His steps, which were getting closer and closer to that gigantic sea, left the mark of his shoes on the soft white sand, the sea was now calm, with small waves crashing on the beach. The turbulent waves that were plaguing the sea were the result of Erwin's training.

Once the magician stopped his training, the sea became calm and serene again, but this would not last long. The air was cool and salty, causing Luke to take a deep breath. He reached the edge of the water, where he stayed for a few moments concentrating and trying to go over everything that had happened.

The half-wolf began to focus on Erwin's display of strength, trying to remember how the wizard had moved. Controlling an element without an incantation was no doubt an amazing task, but he imagined it would be possible to recreate this.

Luke began to concentrate his magical power, feeling the energy flow through his body. His mana concentrated from inside his chest to his arms, following it like a current that flowed into the palms of his hands. He visualized the waves of the sea transforming into a solid force and concentrated all his attention on this vision.

His goal was to at least be able to connect those calm waves, making them take the shape he was interested in. With each wave that kept flowing, closer to the sand, Luke was commanding them. Causing the water to flow and group together.

Inside Luke's head there was a single idea in mind, to form a pillar of water in the middle of that sea. A simple way, just to train his idea of manipulating the waves of the sea.

Inside the half-wolf's head, he was visualizing the flow of the water. His hands slowly managed to feel where the sea was going, so that moving it was not different from breathing. It was an automatic act, but at the same time an extremely challenging task.

Slowly, the pillar began to take shape, growing from the churning surface of the sea. With each layer of waves that hit that magic, Luke grabbed the wave and connected it to the pillar of water, which was increasing in size with relative speed.

Soon that spell had grown taller than the largest of the waves. Luke kept his focus, concentrating his energy on the spell, even as the waves began to crash against the pillar. The water around the pillar seemed to glow with a brilliant light, and Luke felt that his magical power was intensifying by the second.

It was an invigorating feeling of mastery over that new method. However, this task was much more challenging than he had imagined. In a few seconds he already realized how there are different factors modifying the flow of the water, such as fish, algae, wind, and even the moon in the sky.

These were different points that made controlling the water much more complex than wind magic itself, something the half-wolf had not even imagined possible. However, his search for new ways to become stronger was real, and in a way, this challenge made him even more focused. With an amazing display of strength, Luke began to charge even more energy into that pillar of water.

This was causing the waves to connect more easily, attracting the water so that the pillar grew even faster. The glow of the energy Luke had concentrated in the pillar made the water look like some kind of glowing crystal, surprising Erwin.

The blue-haired magician then began to clap his hands behind Luke. He was in awe of the half-wolf's power.

"Hahaha my intuition wasn't wrong" Erwin said.

Little by little, the half-wolf was losing control, until there came a time when he could no longer hold that gigantic amount of water. It was a task that, as much as it didn't use up the half-wolf's mana, it still made him tired.

The moment Luke lost control of that pillar of water, Erwin took control of the feat.

With a snap of his right hand, the blue-haired wizard made that pillar of water grow much larger. It flew upwards at a gigantic speed. Quickly the pillar surpassed the size of the academy's forge, and then it went higher and higher until it reached the clouds.

After that, with a second slap, Erwin made the entire pillar disappear, turning it into a strange mist. A cloud ended up forming in the clear sky of that beach, at the same time a gigantic amount of salt was falling to the top of the sea.

"You did very well for a beginner boy, very well..." Erwin said, giving Luke a gentle smile.
