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

Even with the strong regenerative elements in it, one can imagine just how much suffering Harry Potter went through.

Harry Potter had already exhausted all his strength just from struggling in the excruciating pain.

I have absolutely no strength left.

"Master, this experience was far too painful; I really don't want to go through it again."

On the way, Harry Potter whispered his grievances to Lin Yu.

'Take a good look at your current physical condition.'

Lin Yu didn't tolerate Harry Potter's words at all.

Harry Potter was stunned, still reeling from the excruciating pain, and hadn't had a chance to fully process what was happening.

Hearing Lin Yu's words, Harry Potter finally came to his senses and carefully considered the situation.

However, it would have been better if he hadn't felt it at all, because this feeling immediately surprised Harry Potter.

Although the cultivation process was painful, I could personally feel my improvement after each session.

But this time, it felt completely different from before!

If in the past, each improvement was only a tiny bit, which could be clearly felt but was not obvious.

This time, it can be described as a qualitative leap.

Almost all of his bones and blood were replaced.

After going through unimaginable hardships and refinement, the improvement achieved is also enormous.

It's no exaggeration to say that if Harry Potter were to be hit a couple more times, he could confidently say that bullets wouldn't have any effect on him.

If one can train like this every day, then even black magic might not be able to break through one's defenses.

What Ironclad Curse? Compared to myself, it's nothing.

'However, Avada Kedavra doesn't seem to cause direct physical harm.'

As Harry Potter pondered this, his thoughts suddenly began to wander.

"Are you an idiot? Magic is basically just an energy attack. What are you using your internal energy for?"

Lin Yu's annoyed voice echoed in Harry Potter's mind.

Harry Potter couldn't help but instinctively scratch his head after being scolded.

"Although this improvement is significant, don't get too complacent; this is just the beginning."

"If you want to improve further, you'll have to pay an even heavier price."

Lin Yu instructed him, and he knew the ways of tempering the body better than anyone else.

In order to improve step by step, he even disassembled his entire body and then reassembled it.

This level of dedication is absolutely beyond what ordinary people would make.

Although Harry Potter is not yet at that level, it is still necessary to give him a heads-up so that he is aware of the risks.

'ah? ’

Harry Potter was startled by Lin Yu's words.

'No, Master, is there something even more painful?'

"Of course, you haven't forgotten that your internal organs haven't been tempered yet, have you?"

Lin Yu's words silenced Harry Potter completely.

He suddenly felt that his future was utterly bleak.

They made their way to Dumbledore's office, and then Harry Potter remembered something.

"Master, speaking of which, why did you suddenly decide to expose yourself?"

Although Harry Potter knew that Lin Yu never cared about anything else.

Because they don't care, they don't plan to show off in front of others.

But this time, the fact that they were actually planning to show up on their own initiative made him a little suspicious.

I was just feeling a bit bored, and I thought I'd leave you something too.

"Leave me something? What do you want?"

Harry Potter looked puzzled, not quite understanding Lin Yu's words.

'Of course, I want to leave something behind for when I'm gone.'

Harry Potter was stunned upon hearing this.

'leave?'

'Master, where are you going?'

Compared to everyone else, Lin Yu's existence is definitely the one Harry Potter can't do without.

He is now Harry Potter's only family member, the closest and most trusted person in his life.

Even if his parents were to be reborn, they could not reach this level.

But this person, who was like a father to him, suddenly said he wanted to leave.

How could Harry Potter possibly accept this?

'Going home? Where to?'

Lin Yu said lazily, "You don't actually think I was forced into your world, do you?"

'This is merely a wisp of my divine consciousness. I roam the myriad worlds, and yours is but a small part of it.'

Harry Potter fell silent upon hearing Lin Yu's words.

His tone was full of reluctance.

'Master, are you leaving soon?'

'It won't be very fast, at least not until we've figured out all the magic in your world.'

'That's the same reason I appeared before your principal.'

'If it's just you, the level you can access is far too low; I can hardly access more advanced magical knowledge.'

Harry Potter looked somewhat downcast upon hearing this; what Lin Yu said was indeed the truth.

'Master, it's all my fault for dragging you down.'

'It's not a matter of being a burden or not; it's just something I do out of interest.'

Even if that weren't true, I wouldn't be staying in this world for very long.

'The world I live in is still under threat, and I must find a solution as soon as possible.'

Is there anything else that can threaten you, Master?

Harry Potter said incredulously, in his mind, Lin Yu was already the most powerful being.

The world is full of wonders, which is why I tell you to keep a humble heart.

Because you never know how much stronger you might become.

As they spoke, the two arrived at Dumbledore's office.

"Boom, boom, boom."

Professor Sprout knocked on the door, and Dumbledore's voice came from inside.

"Please come in."

The door opened, and Dumbledore smiled as he looked at Harry Potter and Professor Sprout.

"Professor Sprout, Mr. Potter, is there anything I can help you with?"

Professor Sprout glanced at Harry Potter, who nodded and spoke first.

"It's like this, Principal. My mentor would like to meet you."

"master?"

Dumbledore paused slightly, but didn't show much surprise. He simply nodded gently and said...

"Of course, I don't know where your master is."

Hearing their conversation from the corner, the Sorting Hat tucked itself deeper into its hiding place, looking frightened.

Dumbledore was quite perceptive to this, but he didn't reveal anything.

"master."

Harry Potter uttered a single, soft word, and time seemed to stand still in the entire office at that moment.

A phantom figure slowly emerged from Harry Potter's body.

The overwhelming and powerful aura made the people in the room feel a deep sense of oppression.

This kind of pressure is beyond what ordinary people can generate.

The pressure felt like being at odds with the world, like facing a high and mighty deity.
