Being at Hogwarts, something's not right with this system.

What a joke! Last time, Lin Yu was tricked by Draco into a duel, but not only did Draco not show up, he also secretly tipped them off, getting the administrator Filch to arrest them.

So how could Lin Yu possibly fall for it again this time?

People say you learn from your mistakes, but you can't keep learning from your mistakes, can you?

You learn from your mistakes, and they're all the same?

Are you kidding me?

Moreover.

Lin Yu looked Draco up and down, then said, "And after you took the Marrow Cleansing Pill, wasn't the effect quite good?"

He was right; Draco usually looked pale and somewhat unhealthy.

But now Draco's complexion is fair and rosy, and he even looks a bit like a pretty boy.

Draco's hair also looked even more dazzling, as if he had applied hair wax.

Not to mention, Draco not only looked much healthier, but he had also grown taller and become more robust.

Draco's change was quite obvious; even the Slytherin kids were surprised when they looked over.

Clearly, they hadn't expected the Marrow Cleansing Pill Draco had to be so effective.

Although the process after taking the Marrow Cleansing Pill was a bit complicated.

"You," Draco glared at Lin Yu, and after a long pause, he said, "You specifically told others, like Granger, like Potter and those damn Weasley brothers. You told them to go to the bathroom to take the Marrow Cleansing Pill, so why didn't you tell me? And I even paid for it. You took a thousand Galleons from me, Lin Yu."

Lin Yu shrugged: "Malfoy, Hermione is my girlfriend, everyone at Hogwarts knows that now. As for Harry and the others, they're my friends. But what about you, Malfoy? You keep causing me trouble and even tried to kick me out. Laughable! Why should I remind you? Besides, even though you embarrassed yourself, you gained far more. Don't tell me you don't know how much you've changed."

Draco remained silent.

In fact, he could indeed feel that after taking the Marrow Cleansing Pill, his body and the indescribable sensations within it had changed significantly.

It could even be said that this is a revolutionary change, and it couldn't be better.

So even though Draco had made a huge blunder, he only came to Lin Yu to question him, but he didn't go to anyone else to complain or tell his father directly.

It's worth noting that Lucius Malfoy once drove Dumbledore away during the reopening of the Chamber of Secrets in the original books.

Lucius should currently be serving on the Hogwarts Board of Trustees, so he still wields some real power.

The Board of Trustees is said to be the body that can decide whether Hogwarts opens or closes, and appoint the headmaster, and is not subject to interference from the Ministry of Magic.

However, judging from the fact that the Ministry of Magic directly appointed Umbridge to intervene in Hogwarts, it seems that the Ministry of Magic could still control the situation.

Of course, the reason why Umbridge has never been able to directly enter the principal's office is probably because she has not been recognized by the school board.

Far away.

Draco ultimately had no way to deal with Lin Yu.

In Lin Yu's words, you pay money, and I sell you the Marrow Cleansing Pill. It's a cash-on-delivery transaction, and neither of us owes the other anything.

As for Draco's embarrassing incident, that's just a normal effect of the Marrow Cleansing Pill.

Anyway, you've already benefited, so what's the big deal about losing face a little?

As for what he didn't mention, they don't teach you magic spells just because they sell you a wand, right?

This was a fallacy, but Draco was helpless and could only leave cursing.

"Are you sure you want to offend him?" Hermione pulled Lin Yu down to sit. "You've made him lose face this time. Aren't you afraid of his father, Old Malfoy, retaliating? I heard his father is on the school board?"

Lin Yu said nonchalantly, "If we beat up the smaller ones and the bigger ones come, and they really have no shame, then we can just break off all pretense of civility. Anyway, Malfoy has been causing us trouble all along."

Anyway, he never intended to please the Malfoys from the beginning, and they were bound to break off relations sooner or later.

It's about seeing what the Malfoys will do then.

Will they sink into depravity along with Voldemort, or will they wake up early and abandon darkness for light?

Old Malfoy still has some sense; hopefully, they can make the right choice.

However, for Lin Yu, these are all minor matters once he and Hermione have truly grown up.

Their most important task right now is to seize the time and grow as quickly as possible.

Time, though seemingly flowing slowly, has been secretly and swiftly passing by. Not only has September passed in the blink of an eye, but October is also fast approaching its end.

During that time, on September 19th, Lin Yu also helped Hermione celebrate her birthday. Of course, he had already prepared a birthday gift, so there was no need to give it to her on the day.

In addition, Lin Yu completed dozens of missions during these two months.

This also allowed Lin Yu to obtain hundreds of thousands of low-grade spirit stones.

This is because Lin Yu always bargains with the system's rewards. For example, he now has a family to support, and Hermione was the wife the system arranged for him.

After all, Hermione is also Nalan Yanran, Xiao Xun'er, Medusa, and later she played countless other roles such as Xiao Zhao, Zhao Min, Zhou Zhiruo, Huang Rong, and Xiaolongnu.

Of course, without exception, they are all the female leads of the "protagonist".

The system always had to compromise, not only giving Lin Yu additional rewards but also asking for more things from him.

For example, he also asked Hermione for a magic ring and a sword.

The sword was called the Heavenly Gang Sword. Lin Yu later swapped it with Hermione, giving her the Cloud Mist Sword and refining the Heavenly Gang Sword himself.

In addition, after obtaining sufficient spirit stones, Lin Yu and Hermione's cultivation levels have both reached the ninth level of the Qi Refining stage.

This cost them hundreds of thousands of spirit stones.

It should be noted that the two of them spent 16,000 low-grade spirit stones each when they advanced to the sixth level of the Qi Refining stage.

When they advanced to the seventh level of Qi Refining, they both spent 32,000 low-grade spirit stones.

Refining Qi to level eight requires 64,000 low-grade spirit stones.

At the ninth level of Qi Refining, each person needs 128,000 low-grade spirit stones.

So it took them two whole months to reach the ninth level of the Qi Refining stage.

Currently, Lin Yu still has over 200,000 low-grade spirit stones, which, according to his calculations, is just enough for one person to advance to the tenth level of the Qi Refining stage.

However, Lin Yu is now hesitant about one thing: he still has a reward in the system space that he hasn't extracted yet.

That was the reward that could directly raise one level of cultivation in the Qi Refining stage.

What Lin Yu needs to consider now is whether the Qi Refining Stage is considered to be at its peak at the tenth level, or whether he needs to continue cultivating after reaching the tenth level to achieve the peak.

There's a word game involved here.

If ten levels is considered the Great Perfection, then as long as one's cultivation reaches the tenth level of the Qi Refining stage, it is already the Great Perfection, which means it's time to consider Foundation Establishment.

But if one wants to continue cultivating to the Great Perfection after reaching the tenth level, how many spirit stones would be needed?

Lin Yu was considering this issue because the reward could only raise his cultivation level by one layer in the Qi Refining stage, meaning it would be useless once he reached the Foundation Establishment stage.

He was thinking about whether he should claim the reward and level up to level ten himself, and then use the spirit stones to help Hermione level up to level ten.

Or is it that he wants to use spirit stones to first reach level ten, and if he wants to continue cultivating after level ten, he can maximize the effect of that reward?

But what about Hermione? Should he let Hermione fall behind him by one or two levels?

This is the thing that's been giving Lin Yu a headache lately.
