After the two entered the castle, it was changed to Kewen, the 'repeated criminal', to lead the way.

After coming to the kitchen with ease, Dumbledore moved the 'eight-eyed giant spider' that he had killed for no reason.

Only then did Kewen understand why Dumbledore killed an eight-eyed giant spider suddenly when he was in the spider's lair. It turned out to be for the present.

Next, the house-elves cooked a spider feast for the two of them, and the services were very thoughtful.

Dumbledore watched the whole process, watching all the services Cowen enjoyed, and he couldn't help but wonder whether to laugh or cry.

Obviously, Kewen has violated the school rule of 'no night travel'.

Following Kewen's example, Dumbledore also enjoyed some spider legs. After the meal, he followed Kewen all the way into the Room of Requirement.

Dumbledore felt that the surprise he had received from Cowen this evening was simply too much.

If he hadn't followed Cowen, Dumbledore would have almost forgotten that there was such a secret room.

Because of the presence of Dumbledore, Kewen did not use the "Three Fights" to digest the nutrition of the spider leg meat. He chose to use a magic spell to conjure a treadmill-like carpet, and then ran on it.

Although this is a waste of nutrients in the body, after all, he can't explain the "three battles", and he can only reluctantly waste the nutrients and energy that are constantly dissipating in the body.

After a while, the spider leg meat in Dumbledore's stomach began to digest.

Dumbledore felt it carefully for a moment, and said to Cowan suspiciously: "Is this the feeling? Feeling a little warm in your stomach?"

"Yes sir." Kewen replied while running at a constant speed: "After I ate it for the first time, I felt very energetic and had nowhere to vent my energy, so I used vigorous exercise to offset that feeling."

"After two days, I found my strength increased."

Dumbledore nodded slightly when he heard the words, thought for a moment and said, "Maybe it's because you eat a lot... Speaking of which, I just found out that Kewen you eat so much. Is it because of the three meal times in the academy? Can you get enough to eat?"

"Mostly." Cowen responded, a little embarrassed, "until I discovered the kitchen..."

"Hehehehe..."

Dumbledore let out a chuckle, and did not intend to pursue Kewen's 'night tour'.

Taking out his pocket watch and looking at the time, Dumbledore said, "Okay, I'll be here today, old man, I'm no younger than you, so you should go back to the dormitory earlier to sleep."

"Uh that..." Cowen turned to look at Dumbledore while running, and said again embarrassedly: "Almost every day... I rest here..."

Dumbledore was stunned, and was silent for a moment before raising the volume slightly and saying in surprise, "Every day?"

Kewen smiled and nodded: "Unless there are other things, I will come here every day after curfew to practice magic spells, and then ask the 'House of Requirement' to arrange a bedroom for me..."

"Merlin's beard..." Dumbledore sighed, and at the same time subconsciously raised his hand to stroke his long snow-white beard, staring at Kewen, really not knowing what to say.

In the end, it was because Cowen's performance was too good that Dumbledore could only choose to turn a blind eye.

Simply, take the situation of Kewen constantly violating the academy's 'curfew rules' as an exception to the genius.

Then, when Dumbledore was leaving, he turned around and said to Kewen, who came out to show him off: "I remember that the Ministry of Magic rewarded you with a thousand gold Galleons, right?"

Corwin didn't know why Dumbledore asked this, but he nodded in response.

Dumbledore continued: "If you're willing to pay, I might be able to get you some meat from other magical creatures."

Having said that, Ke Wenke came to his senses, and immediately put on his face with surprise.

Dumbledore noticed Kewen's expression, and he shook his head helplessly and said, "It's a kind of research, maybe in the future you can also publish a book called 'Where's the Magical Recipe'."

After Dumbledore finished saying this in a joking tone, he smiled and blinked his left eye at Cowen: "But then you have to be careful, be careful that Newt runs over to fight you, haha..."

Amused by his own joke, Dumbledore smiled and turned away, and soon disappeared.

Kewan was stunned by Dumbledore's "Old Urchin" behavior, until he could no longer hear the other's footsteps, he shook his head helplessly and returned to the practice room.

Cancel the 'Magic Treadmill' and start practicing the 'Three Fights'.

While playing the routine, recalled today's experience.

To sum up, the end result is a positive development.

However, suddenly thinking that there will be three months of confinement after that, Kewen's expression became bitter again.

...

...

Time is like flowing water, the gurgling keeps moving forward and never stops.

After three months of miserable confinement, Cowen continues to strive to improve himself.

While diligently practising the new spells constantly obtained from the library, increase the study of 'ancient magic literature' and 'transfiguration'.

At the same time, because he felt the indulgence and laissez-faire of the principal and professors, Kewen increased his harassment of Professor Snape.

He went to Snape's office almost every day, and had the cheek to ask the other party for questions related to Potions.

Snape was uncomfortable, but even though he often deducted points from Cowen in the office, he failed to block Cowen's hippie smile.

Therefore, Snape could only reluctantly accept the reality, and was approached by Kewen almost every day, asking all kinds of related or unrelated questions.

In the end, Professor Snape was accustomed to the life of a teacher who faced Kewen with a cold face every day, and made excuses to deduct points for Kewen when he had no chance.

On the other hand, Dumbledore did as he said, and spent Cowen's thousand gold Galleons to find the flesh of many different kinds of magical creatures for Cowen.

In the end, Kewen found that the bigger the creature, the higher the nutrition in its meat.

After reporting this situation to Dumbledore, Dumbledore terminated Kewan's 'recipe' experiment, but still spent Kewan's bonus to let the kitchen continue to cook a small stove for Kewan.

In a flash, the time is approaching the end of the period.

In the middle of the night, in the laboratory provided by the Room of Requirement, Kewen held a crucible in both hands and cheered loudly: "YES! It finally succeeded!"

After jumping to celebrate, Kewen immediately ran out of the laboratory holding the crucible.

After leaving the laboratory, Kewen finally came to his senses after seeing the dark environment around him. It was still midnight.

Helpless, he could only forcibly suppress the excitement in his heart, turned around and returned to the room of responsiveness.

Early the next morning, Kewen, who had been up all night, carefully picked up the crucible again and quickly left the bedroom provided to him by the Room of Requirement.

After pinpointing the time for breakfast, Kewen entered the auditorium in a hurry...
