Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

Dumbledore's eyes were filled with complex emotions. Even with his wisdom accumulated over so many years, he couldn't fully comprehend Lin Yu's power.

The professors were also thrown into chaos; they had no idea that such a powerful being resided within Harry Potter.

At this moment, Lin Yu slowly spoke, the booming sound like rolling thunder:

"Harry, don't be sad. As long as you try, you will find me one day."

As the words fell, an overwhelming martial will descended completely.

At this moment, the world seemed to fall silent. All sounds and objects were terrified by this terrifying martial will. However, this world seemed to have detected something that should not exist. Countless dark clouds appeared out of thin air, and enormous magical power created these things out of thin air, bringing with them countless bolts of lightning.

"I see. That explains why there are no powerful beings or extraterrestrial demons in this world."

Lin Yu smiled slightly.

Although the magic system in this world is weak, its potential for magical power is undeniable, as evidenced by the various soul-based dark magics that Voldemort mastered.

Only now does he understand.

All the magic is controlled by the will of this world itself. It has covered the entire world with a protective shield, which not only prevents powerful extraterrestrial demons from finding it, but also eliminates some weak extraterrestrial demons.

He was able to arrive here entirely because he was just a seed, and the mysterious turbulent currents outside also allowed him to enter this world.

As these thoughts flashed through Lin Yu's mind, lightning descended from the sky. Like twisted lightning snakes, it carried a world-destroying aura, wanting to completely annihilate Lin Yu, this anomaly.

A smile appeared on Lin Yu's lips. He stretched out his hand and waved it gently. His powerful mental energy instantly transformed into countless streams of hatred and emotion, enveloping the lightning snakes.

The Razer instantly disintegrated upon contact with the power of hatred, transforming into the purest form of magic.

"Since you're here, you might as well borrow it."

Lin Yu extended his finger and touched the massive mass of magical power.

The magic instantly transformed back into lightning, and then continued to evolve, transforming into a giant sword of thunder.

Lin Yu gripped the thunderous greatsword and gently slashed down at the dark clouds in the sky.

"Crack!"

A sound that seemed to shake the heavens and earth resounded, and then the people on the ground, who were completely speechless, witnessed a scene they would never forget for the rest of their lives.

The dark clouds in the sky split cleanly in two, revealing not a clear sky, but a pitch-black crack.

Of course, if you look closely, you can also see a faint light through this crack.

Dumbledore stared blankly at the scene before him, knowing that Lin Yu had opened the spatial barrier of this world.

Just then, an extremely evil aura descended.

Dumbledore immediately became alarmed, staring intently at the dark crack.

In the deep darkness, something seemed to be wriggling.

A strong sense of being spied on and a feeling of the strange filled everyone's hearts.

"This feeling is many times more evil than Voldemort's..."

Dumbledore murmured, a feeling that if these dark things were allowed to descend, the whole world might be destroyed.

However, Lin Yu didn't care at all, and instead smiled faintly:

"It came at just the right time."

He reached out and scooped up countless demons from the darkness.

The demon let out an unconscious howl, which sounded extremely piercing to everyone's ears. Then, to everyone's astonishment...

These demons were kneaded in Lin Yu's hands like clay, and the strange feeling disappeared instantly.

At this moment, Lin Yu took a deep look at Harry Potter, then took a step forward, transforming into a wisp of light, and directly disappeared into the rift.

With the tearing power of hatred gone, the world's will immediately sprang into action, surging forth with magical energy to fill the cracks, and the clear blue sky reappeared.

If the scene from just now hadn't been so deeply etched in everyone's minds, it would have seemed as if nothing had happened.

Harry Potter, on the other hand, kept staring intently at Lin Yu, as if trying to imprint everything that had just happened into his mind.

Just then, a point of light that no one would notice slowly drifted down in front of Harry Potter.

Harry Potter was slightly taken aback, then sensed a familiar aura from it, and quickly reached out to catch the light.

The moment the light touched Harry Potter's hand, it melted away like warm spring snow.

A faint voice echoed in Harry Potter's heart:

“Harry, this is a seed I’m leaving for you. Once you reach a certain level, you’ll be able to easily absorb it. I believe you’ll reach that level soon.”

The sound grew fainter and fainter until it rose straight up into the sky and disappeared completely.

Harry Potter clenched his fists, his heart filled with unwavering resolve:

"Master, I will definitely come to find you."

Meanwhile, Harry Potter's friends, having recovered from their shock, rushed towards him, eager to ask him about Lin Yu.

Of course, Lin Yu was unaware of all of this.

Because he is currently searching for his way back in that dark, eerie world of extraterrestrial demons, shrouded in a hazy glow.

His soul continued to advance, and as he went deeper, a dark, scarlet light obscured his form.

Magic is a magical power, possessing the ability to create something from nothing. To a certain extent, it shares similarities with emotional power.

Through Lin Yu's research, the two can now be converted into each other. Although there will be some losses, in the world of Harry Potter, as long as one has strong mental power, one can easily control the magic power existing in the atmosphere.

Therefore, his current emotional energy is quite abundant, enough to simply conceal his aura for him to wander in this dangerous world for a long time.

However, if he can't find his way back, Lin Yu is very likely to be eventually annihilated by the various undercurrents of power in this world of extraterrestrial demons.

"Well, speaking of the Harry Potter world, there is a world will, but it has low intelligence. It's more like a program with the most basic logic set up. It will automatically protect the original world and maintain the balance of the world."

But the world of fox spirits is different. It has been breached, clearly indicating that the world's will is powerless to protect it. The balance within the world has been broken, and its power has naturally flowed into the world of extraterrestrial demons.

This brought about changes to the originally static extraterrestrial demon world, which is why the fox demon world exists within the extraterrestrial demon world like the morning star.

Therefore, if I want to return, I only need to find the undercurrents of various mysterious forces in this world and analyze which one belongs to the fox demon world.

He didn't know how much time had passed when a sudden inspiration struck him, and this idea popped into his mind.

He closed his eyes and carefully sensed the mysterious turbulent currents of energy around him. Soon, a completely different world unfolded before his eyes.

Countless distinct forces roamed within, flowing chaotically through the world of extraterrestrial demons like unrestrained water.

Lin Yu patiently analyzed all the surrounding forces, and soon he detected a familiar aura.

Although it was very weak, appearing so insignificant among the various forces, it still brought a smile to Lin Yu's lips:

"found it!"

Following this slight fluctuation, Lin Yu quickly rushed towards the direction from which it came.

The world, which had seemed static, suddenly seemed to accelerate. Countless extraterrestrial demons flew around Lin Yu, but Lin Yu showed no intention of stopping and tirelessly continued on his way.

In the pitch-black world, time seemed to have lost its meaning, but in Lin Yu's eyes, the gradually becoming clearer force told him that he was heading in the right direction.

He persevered tirelessly, and finally, he saw a bright passage appear before him.

That shape, that aura.

This is definitely the world of fox spirits!

"Finally home."

Lin Yu let out a long sigh of relief. Even someone as powerful as him couldn't help but develop some strange feelings after spending so much time in the darkness.

This seems to be something etched deep within the human soul.

As long as Lin Yu still experiences emotional fluctuations, these things will arise.

He keenly sensed that this change might be related to the emergence of extraterrestrial demons, but if he wanted to investigate it, he would need to conduct research for a longer period of time.

Now that I'm back, I naturally need to rest for a while.

Lin Yu was slightly excited and rushed towards the passage without saying a word.

The bright light grew stronger and stronger before their eyes, and the aura of the fox demon world became increasingly intense. In this dark and sunless world, this breach was as bright as a lighthouse in the darkness.

Any extraterrestrial demons in the vicinity will definitely be attracted here.

These extraterrestrial demons almost filled the breach, but they posed virtually no obstacle to Lin Yu.

He traversed countless extraterrestrial demons, and finally, at a certain moment, he reconnected with his original body after a long period of separation!

Tushan, the Imperial Palace.

Under the influence of the knowledge of the Kingdom of Ster brought by the previous clone, this place has become more technologically advanced.

For example, the main gate has been transformed into a voice-controlled gate full of technological elements, which can be opened automatically by simply saying "Open Sesame".

For example, the statues engraved on the walls have been transformed from completely inanimate objects into intelligent robots with certain defensive attributes.

These designs, brimming with a touch of chuunibyou (a Japanese term for someone with delusions of grandeur), were all created by others who pestered Tu Shan Rongrong. The technology of the Kingdom of Ster made the originally monotonous life much more interesting.

Lin Yu sat on a massage chair in the courtyard, looking at the completely transformed ancient and technological buildings, and chuckled to himself.

Although Tu Shan Rongrong was being pestered by others to do this and that, she herself seemed to be immersed in it.

Of course, the other party will always say that this is just putting this knowledge into practice.
