Naruto: The strongest fire style Blade Jakka!

On an ordinary morning in 2024, the world changed. The originally peaceful city was suddenly shrouded in a strange energy fluctuation, and various animals began to show unprecedented superpowers. And our protagonist Li Yi accidentally gained the ability to summon lightning out of thin air during this change.

"Ding, the power awakening is successful!" A voice suddenly sounded in Li Yi's mind. He opened his eyes suddenly and found himself standing on a messy street. There were tall buildings all around, but they were already dilapidated. The air was filled with the smell of burning, as if it had just experienced a catastrophe.

Li Yi felt an inexplicable excitement and anxiety in his heart. He tried to mobilize the power in his body. In an instant, a bolt of lightning burst out from his fingertips, streaking through the sky and hitting an abandoned building in the distance. With a loud bang, the building instantly turned into ruins.

"Is this... my superpower?" Li Yi muttered to himself, his heart filled with awe for the unknown power. He understood that this world was no longer the same as before, and the end of the world seemed to have really come.

At this moment, that voice rang in Li Yi's ears again: "Ding, the survival system is activated! Ding, the end of the world officially begins! Ding, soul binding is successful!" A huge light screen appeared in front of him, displaying various data and task information.

"Mission: Doomsday Survival! Requirements: Survive one day in the doomsday! Reward: One mission point, randomly activate a system function." Li Yi cursed in his heart, this system came at a really bad time, but he also understood that in today's world, the only way to survive is to become stronger.

Li Yi began to get familiar with his ability, and he found that summoning lightning not only consumed a lot of physical strength, but also caused great damage to the surrounding environment. However, just as he was immersed in the joy of practicing his ability, a group of mutant animals quietly approached.

These animals were huge, with red eyes, and had obviously been corrupted by the mutation. They exuded strong hostility and pounced towards Li Yi. Seeing this, Li Yi immediately mobilized the power in his body and summoned several lightning bolts to repel them.

But these mutant animals seemed tireless and attacked Li Yi again and again. Li Yi gradually felt exhausted and thought to himself that something was wrong. At this moment, the system prompt sounded again: "Ding, the host is detected to be in a dangerous state, and the auxiliary function is automatically turned on!"

A beam of light shot out from the light curtain and enveloped Li Yi. Li Yi immediately felt a warm current flowing through his body, and his physical strength quickly recovered. He seized this opportunity and summoned powerful lightning again to destroy all the mutant animals around him.

"It's finally over..." Li Yi sat on the ground, gasping for breath. He understood that this world was no longer the peaceful world it once was. Various mutant creatures emerged one after another, and humans were facing an unprecedented crisis.

As a survivor with superpowers, he must take on the responsibility of saving the world. Li Yi stood up and looked at the ruins in the distance, with a firm belief in his heart.

"No matter how many difficulties lie ahead, I will survive!" Li Yi clenched his fists and resolutely embarked on a doomsday journey full of unknowns and challenges. As his figure gradually faded away, the dark clouds in the sky began to dissipate, and a ray of sunlight penetrated the clouds, illuminating the earth, as if foreshadowing the arrival of hope.

In the depths of the ancient Cangmang Mountains, there are many rare and exotic animals according to legend, and the Green Lion Monster is the most ferocious one among them. At this moment, it is confronting Li Yi, and the air is filled with a tense atmosphere. Li Yi stood on the top of the mountain, his clothes fluttering in the wind, his eyes like torches, staring closely at the behemoth in front of him.

The green lion monster was as big as a mountain, with its hair standing up like steel needles, its eyes as red as torches, and it exuded endless violence. It roared, and the valley shook, with sand and rocks flying everywhere. Li Yi knew that this was a life-and-death battle, and if he was not careful, he would be killed by the lion.

However, Li Yi did not retreat. He took a deep breath, circulated his internal Qi, and quickly formed seals with his hands. As the seals changed, the towering mountain in front of him seemed to be given life and began to tremble violently. Rocks rolled down, dust flew, and the whole mountain seemed to respond to Li Yi's call.

"Get up!" Li Yi shouted, and pushed forward with both hands. Miraculously, the mountain rose into the air, spinning and expanding rapidly in the air. In the blink of an eye, it turned into an extremely majestic peak, pressing down on the Green Lion Monster.

Seeing this, the Green Lion Monster was not to be outdone. It pushed its limbs hard, and the ground instantly cracked into countless cracks. Its entire body soared into the air like an arrow, heading straight for the flying mountain. In the air, the Green Lion Monster opened its bloody mouth and spewed out a stream of blazing flames. The flames coiled around the mountain like a fire dragon, trying to burn it.

However, Li Yi was well prepared. He kept changing spells with his hands and muttering something. The mountain was not damaged at all by the burning flames, but became stronger. A layer of light golden light appeared on the surface, as if it was covered by an invisible shield.

"Boom!" The mountain and the green lion monster finally collided in the air, making a deafening noise. The huge impact force made the entire mountain tremble, and countless birds were startled and fled in all directions. The green lion monster was smashed to the ground by the mountain, and its huge body smashed a deep pit on the ground, and dust flew up.

But the Green Lion Monster did not give in. It struggled to climb out of the deep pit and roared angrily again. Li Yi saw this and thought to himself that it was not good. This Green Lion Monster was indeed very powerful. He had to go all out to subdue it.

Li Yi formed seals with his hands again, and the Qi in his body surged out like a tide, pouring into the mountain. The mountain slowly rotated in the air, and countless mysterious runes appeared on its surface, exuding an ancient and powerful aura. As the runes flickered, the power of the mountain became stronger and stronger, as if it could suppress all evil spirits.

"Go!" Li Yi gave an order, and the mountain pressed towards the green lion monster again. This time, the green lion monster seemed to feel unprecedented pressure, and it no longer charged blindly, but lay on all fours, roaring softly, trying to resist the suppression of the mountain.

As the mountain continued to descend, the Green Lion Monster's body began to tremble, its hair stood up, and the red in its eyes gradually faded. Finally, under the weight of the mountain, the Green Lion Monster could no longer hold on and fell down.

Seeing this, Li Yi let out a long sigh and put away his spell. The mountain slowly dissipated in the air, turning into countless dust, floating in the valley. After this thrilling battle, Li Yi knew that although he won, he also paid a heavy price. He sat cross-legged and began to regulate his breathing to restore his internal energy. The green lion monster lay quietly in the deep pit, as if it was asleep, and the valley returned to peace again.

Li Yi stood on a vast plain, stunned. He would never have thought that an accidental geological expedition would lead him to discover a secret hidden on Earth for thousands of years - the inner world. This place is full of fantastic scenes, completely different from the surface world, as if it is another universe.

The sky of the inner world was a deep purple, and the clouds were like flowing magma, emitting a fiery light. The surrounding mountains were made of various crystal clear minerals, shining with colorful luster. The air was filled with the smell of sulfur, but it was not pungent, but instead made people feel a unique freshness. Li Yi knew that he had stepped into an unprecedented and wonderful realm.

There are many strange creatures living here. Some are like giant butterflies, with bright scales on their wings, sprinkling starlight when they flap; some are like the legendary unicorns, with snow-white bodies and colorful lights on their horns, jumping lightly among the ores. Li Yi walked forward carefully, fearing that he would disturb these beautiful creatures.

He walked along a winding path, and heard the sound of gurgling water. Not far away, a silver river was rushing, and the water was glittering with silver light, as if the flowing water was liquid stars. Li Yi scooped up a handful of river water, which was cool and sweet, melting in his mouth, nourishing his heart.

As the exploration deepened, Li Yi discovered that the inner world of the earth not only had fantastic scenery, but also contained endless mysteries. The plants here could emit light and heat, providing light for the entire world. The towering trees, with lush branches and leaves, emitted a soft light, and the trunks were covered with various exotic fruits. Li Yi picked a fruit, took a bite, and immediately felt a warm current flowing through his body, and his spirit was lifted.

Deep in the center of the earth, Li Yi also discovered an ancient city. The city's buildings were made of unknown metals, shining with a silver-gray luster and strange shapes, as if they were masterpieces of alien civilization. The city was silent and seemed to have been abandoned for a long time. But Li Yi found some stone tablets with strange symbols carved on them in the city square. After careful study, he was surprised to find that these symbols actually recorded the history and culture of the center of the earth.

It turns out that the inner world was once a highly developed civilization. They mastered advanced technology and were able to use the energy of the inner world to create all kinds of magical inventions. However, due to a sudden disaster, this civilization eventually declined. Li Yi felt an inexplicable emotion in his heart, and felt sorry for this disappeared civilization.

Just as Li Yi was immersed in the history of the Earth's core, he suddenly felt a tremor. The surrounding mountains began to shake, and the ore fell. Li Yi realized that a major earthquake might be about to happen in the Earth's core. He did not dare to hesitate and immediately ran back the way he came.

After a difficult journey, Li Yi finally returned to the surface world. He looked back and the geological wonder had disappeared from his sight, as if nothing had ever happened. However, he would always remember the fantastic scene of the inner world and the thrilling adventure.

Li Yi knew that the secrets of the inner world should not be disturbed by the outside world. He decided to bury this adventure in his heart and make it the most precious memory of his life. Perhaps one day in the future, when the earth opens its arms to him again, he will step into that mysterious land again and continue to explore the mysteries of the inner world.
