Isekai : Strongest Spirit System

In the morning when dawn had just appeared, the raindrops and gusts of wind continued to howl, and a young man jumped out of bed when he heard the loud sound of the alarm on the table, then he stepped into the bathroom to wash his face and prepare all the things needed.

Seeing the bright morning, he decided to open the bedroom window and his white hair was slightly fluttering in the morning breeze. aged between 16-17 years old, very athletic build and cute face, enough to attract the attention of many young girls.

His name is Kenzo Reygan, since he was only 5 years old, his parents had to take their lives because of an accident.

He who originally lived in the city was finally brought back to his hometown, and now he lives alone with his grandmother in a small village at the foot of the mountain.

Since childhood he helped his grandmother look for medicinal plants in the wild, that's what made him love nature so much that he also had a hobby of adventure.

This time he was ready to go up the mountain looking for some medicinal plants that were around the slopes and peaks of the mountain, for him it was very pleasant, being able to stand on the top of the mountain was one of the atmospheres that could paint his best smile.

He was about to climb a mountain with a crater covered in blue flames, the mountain was in the southeast Asian island nation that he was also part of, and when he thought about it, his heart almost didn't beat with impatience.

"Finally I'll be at the top again," A smile full of joy and passionate passion graced his face.

"Grandma, I'm leaving first!" Kenzo shouted as he said goodbye to his grandmother, a large bag containing several bottles of drinking water, snacks, and other equipment tightly pressed against his back.

"Careful!" Said, his Grandma.

"Mmm." Kenzo nodded and then walked out of the house. After that, he raised his hands to pray fervently for his safety while gazing at the towering mountain in front of him.

He began to walk, passing through local people's fields, vast grasslands, dense forests, and cliffs, things that had become his daily habit.

During his journey to the top, he collected many medicinal herbs. After a full day of climbing, he had traveled 2/3 of the way, and to be precise around 04.00 in the morning he had managed to reach the top of the mountain, in front of him was a large crater with a poisonous green lake full of sulfur.

But the most amazing thing was the sight of the blue flames that seemed to flow from the cliffs of the crater, something Kenzo always missed.

"This is the beauty of nature that will always be engraved in my mind," Kenzo muttered as he sat relaxed resting his slightly tired body and covered in sweat and dust, enjoying the view in amazement.

But moments later Kenzo saw an oddity occur in the blue flames on the cliff of the crater, he rubbed his eyes a few times to confirm his vision.

"The fire is growing? No! The fire is rising, could it be carried away by the wind?" Kenzo frowned and swallowed a little, he had often seen the blue flames on the cliffs of the mountain crater, but who saw it now was a little strange, it was the first time this had happened.

Full of curiosity, his gaze began to follow the blue flames that rose as if being blown away by the wind.

In an instant his eyes widened with his mouth gaping as if he was seeing a ghost, without realizing he immediately stood looking up at the sky with a deathly pale face, he almost forgot to breathe.

Above it appeared a giant blue fire magic circle that covered the entire mountain peak, the magic circle was already fully formed at an altitude of about 100 meters from the top of the mountain.

It was the same as what he often saw in his favorite fantasy or magic genre anime series, and of course, it couldn't happen in the real world.

"No! This can't be, I must have seen it wrong," Kenzo reassured himself and rubbed his eyes repeatedly, then patted his cheeks quite hard.

Slowly he tried to open his eyes hoping what he saw was just an illusion.

But what happened was just the opposite, the blue flames that came out grew bigger as if everything was being sucked in by the blue magic circle above it.

"Shit, this isn't good, I don't know what's going on, but I have to go right now!" Kenzo's mind was full of fear.

Kenzo spontaneously bent down trying to reach for his bag, intending to quickly descend from the top of the mountain.

"Boom."

The ground he was standing on suddenly began to shake violently as if a great earthquake had occurred. Sensing that, Kenzo panicked, he was at the top of the mountain and of course, he understood the danger of earthquakes when someone was at the top of the mountain.

And sure enough, before he had time to react to curl up on the ground, his body immediately wobbled and was flung down into the cliff.

"Woe!"

Kenzo glared in disbelief, knowing he had slipped and was thrown towards the cliff below, he could only close his eyes resignedly sure of his death.

At that moment his thoughts went to the only important person in his life, "Grandma, I'm sorry, I can't go back, I'm sorry, I hope you are always okay." Her tears shone with sadness and guilt.

For a moment he felt warmth envelop his body, but slowly began to heat up, and continued to increase, more and more now he felt as if his skin was burning.

"Am I thrown into hell? Of course, after all, I've never done well in this world." Kenzo thought with a bitter smile, he didn't expect that after a sad death, he would have to be thrown into hell.

Kenzo tried to open his eyes a little, he could only faintly see a giant magic circle that spewed blue flames as if burning the entire mountain peak including himself, before finally, his vision became completely dark.

"Tikk...Tikk...Wurrrgt"

Kenzo opened his eyes wide, and looked up at the ceiling of the cave which was filled with purple and blue crystals, he immediately got up and sat down, examined his body, and looked in all directions.

"Not the slightest wound! Where am I now?" Kenzo muttered in confusion, he found himself in a cave filled with purple and blue crystals, then in front of him was a waterfall.

He also now realized that he was in the middle of a magic circle with the same color and pattern as the one he saw on the top of the mountain.

In his confusion, he tries to remember everything that happened, but suddenly! "Aaaaaah... Damn! What's going on with my head," Kenzo felt his head throb violently as if it was ready to explode.

Then he tried to massage his head hard as he curled up and rolled over in pain in the cave.

Not only that, but now he felt that his bones and flesh were being burned and slashed by a very sharp dagger, it was a pain he could never imagine.

Now the sound of his screams immediately echoed in the cave for a long time, almost half an hour. Before finally starting to subside.

[Welcome to the planet Ars].

[Adjustments have been completed].

[You can check your status at any time].

A voice suddenly buzzed in his head.

Kenzo didn't know whose voice was buzzing in his head, but he could tell it was the softest and most authoritative voice he had ever heard in his life.

He tried to slowly open his eyes, and now what happened next was that the cave that was a little dark had now become bright blue, all the crystals seemed to glow reflecting a very bright blue light.

"Huuu... Huuuu"

Kenzo started to catch his breath, his body was covered in sweat, but the pain that had lasted for almost half an hour had completely disappeared.

Now he saw a slightly different scene, the cave had been enveloped by a bright blue light.

With a bit of confusion, Kenzo tried to get up and subconsciously looked to the right side, his eyes narrowed slightly when he saw the tip of the blue flame that looked like wings.

He was very curious and immediately took a closer look, now he gulped with wide eyes, the blue flame that resembled a wing-tipped right at his back.

He was so shocked that he just stood up and immediately collapsed with an expression full of fear.

"Dream? Right... This must be a dream." Kenzo thought, he still chose not to believe it, then slowly anxiously turned his head to the left, and in the end, he couldn't help but stare at a pair of blue flame wings 2 meters wide coming out of his back.
