A crossover anime/manga series, starting with Kaguya's fiancé.

Before them, only Lynn and Kaguya's straight figures remained.

Kaguya's breathing became slightly rapid, but her movements as sheathed her sword remained fluid.

Lynn easily flicked the tip of his sword, shaking off the small amount of black liquid that was stuck to it.

The only sound in the passage was the heavy breathing of the Hathor Familia adventurers.

They stared blankly at everything before them, as if they were in a dream.

"We're saved!"

An adventurer's voice trembled.

"LV1... No, this is definitely not the strength of LV1!"

The other adventurer's eyes widened suddenly, his gaze towards Lynn filled with awe.

They didn't even see how Lynn made his move before the shadow monsters fell.

A young man with a scar on his face struggled to his feet;

"Thank you... thank you for saving us."

Kaguya turned around and gave them a cold glance.

"In the underground city, you must never let your guard down. You cannot relax until you reach the surface."

Her words were still stern, but everyone could tell that she was trying to persuade him kindly.

Lynn smiled and nodded. "Let's go! Get your wounds bandaged and your treatment done!"

After they finished speaking, the two did not linger and headed straight for the depths of the sixth floor.

The adventurers left behind by Hathor's Familia remained rooted to the spot.

They watched Lynn and Kaguya's departing figures, their hearts filled with lingering unease.

Are they from the Astrea Familia?

Even a Level 1 newbie is this strong.

In this sixth layer,

Lynn encountered several more War Shadows, and he killed them all without missing a single one.

Because my proficiency level is about to be maxed out.

As the corpse of a battle shadow fell, a pleasant system notification sounded in Lynn's mind.

[Swallow Return] Proficiency has reached 100%.

I've been granted a new entry into the prize draw. Do I wish to participate?

58. The Dark Faction Appears (Please Subscribe)

"lottery!"

Lynn did not hesitate at all.

As soon as he finished speaking, a huge and magnificent virtual roulette wheel appeared in his mind.

The roulette wheel was divided into countless squares, each shimmering with dazzling rewards.

There were divine weapons, miraculous elixirs, cultivation techniques and secret manuals, and even some strange items from other worlds that he couldn't understand at all.

The roulette wheel spun rapidly, the pointer sweeping across one tempting prize after another.

Lynn's heart also jumped.

The last time he drew the [Swallow Return] skill, it directly caused a qualitative change in his combat power.

What will it be this time?

Finally, the roulette wheel slowed down, and the pointer came to a stop on a square that was flashing with a flame totem.

【Ding! 】

[Congratulations, host! You have drawn a special ability—Avatar: Fire Manipulation!]

【Avatar: The Last Airbender】: An ability originating from the world of Avatar: The Last Airbender. It allows the user to emit flames from their limbs, mouth, and even ears. Maintaining a constant energy balance is crucial for launching direct, continuous attacks. In addition to controlling existing flames, the user can also release flames independently. With practice, the user can even use powerful flame jets to fly.

Fire control technique?

Lynn was stunned for a moment, then his eyes lit up with ecstatic joy.

This is a divine skill used by Azura, Elo, and Zoko!

It can be used not only for attack, but also for flying and escaping, and eventually even for generating reverse lightning techniques!

Moreover, the system rewards are not activated by negative emotions like those of the Fire Nation people in the anime.

In short, aside from the inability to transform into nature, this is a more practical ability than the Flame-Flame Fruit.

This is not magic, and cannot be silenced or banned.

It also comes with a set of martial arts techniques that are somewhat related to the Shaolin school.

Lynn couldn't wait to try it.

"Kaguya, look."

Lynn suddenly stopped and extended his right hand.

Kaguya looked at him suspiciously, wondering what he was up to now.

Lynn took a deep breath and stared intently at his palm.

The next second, a cluster of orange-red flames suddenly ignited above his palm, hovering quietly and dancing lively.

Without any chanting, the flames appeared.

"Magic? When did you master magic?"

Kaguya's voice trembled slightly as she grabbed Lynn's wrist and carefully felt it.

"And you don't have any instant-cast, incantation-based magic?"

Lynn smiled, and with a thought, the cluster of flames, like a gentle fire serpent, skillfully coiled and danced at his fingertips.

"I do not know either."

"I learned it after I killed that War Shadow."

Just then, a roar came from the depths of the passage. A lone warrior spotted them and rushed towards them.

"careful!"

Kaguya instinctively reached for her sword.

However, Lynn was faster than her.

Instead of drawing his sword, he took a step forward, lowered his body slightly, and adopted a strange fist-fighting stance.

Facing the charging shadow, Lynn suddenly threw a punch.

"call--!"

A blazing fire dragon roared and surged forth from the wind of his fist, instantly engulfing the battle shadow.

A scorching smell filled the air. Before Zhan Ying could even scream, he was reduced to ashes in the flames.

Kaguya stood there dumbfounded, only half-drawn from her twin swords.

She looked at Lynn as if she were looking at a complete monster.

"you you……"

Kaguya's vocabulary seemed incredibly limited at this moment.

Lynn withdrew his fist, feeling the continuous flow of heat within his body.

[Fire Control Technique] Proficiency: 0.2%.

He can completely control the rewards given by the system.

He could even feel that he could breathe fire from his feet and fly if he wanted to.

This is the art of fire control.

A pure art of manipulating fire through bodily energy, completely different from the magic system of this world.

However, using fire to transform lightning is a different matter altogether.

Of course, Lynn still had to disguise the fire control spell as magic.

"You are really... so strange."

Kaguya finally regained her voice. She slowly sheathed her sword, her gaze towards Lynn filled with complex emotions.

"Is your inexplicable developmental ability really that extraordinary?"

Lynn shrugged, looking completely nonchalant.

"Probably."

He naturally attributed this newfound ability to the mysterious "outside of truth".

Anyway, these inexplicable things can all be blamed on their own inexplicable development capabilities, which saves them a lot of trouble.

Kaguya looked at Lynn and smiled speechlessly.

She couldn't understand it, but that's fine too.

The more powerful he is, the safer he is.

Lynn and Kaguya continued to venture deeper into the underground city.

Kaguya skillfully led Lynn through the seventh, eighth, and ninth floors, without encountering too many monsters.

They arrived at the tenth floor, which was much more spacious, and the air was filled with the earthy smell of soil.

Huge stalactites hang from the rock face overhead from time to time.

Lynn and Kaguya continued downwards, traversing a maze of passages, where the scorching air gradually became humid.

They quickly arrived at the tenth level of the underground city.

“Bardbat bats, they usually inhabit the top of caves,” Kaguya reminded her.
