At the start of the new week, Joel and the three of them are busy working on an outline of the history of magic, and Alan and Marietta are very close.

On the afternoon of Joel and Sergey's trip to Tumbledown Alley to sell books, Alan and Marietta didn't know what they were talking about by the Black Lagoon.

But now the two of them often get together in class and dinner, much to the surprise of the other three in the dormitory.

Although they dislike Marietta's dislike of the poor and the rich, making friends is Alan's own business, and the three of them will not interfere.

Just when the few of them were busy in the dormitory, Joel suddenly received a system prompt.

"Please complete the side quest as soon as possible, otherwise the system will apply penalties based on the failure of the task."

He recalled the task because he had "used" Helis's good fortune to punish him.

Remove the doorknob of Professor McGonagall's office from being discovered...... Isn't it a cheat!

Joel wanted to flip the table when he saw this task, but it was clear that the system was deliberately tricking him.

But if this task is not completed, it will not work, and the system will punish him for eating any food that tastes like canned herring for seven days, and he can't stand it.

There are still 7 days left before the deadline, and there is not much time left for me.

He grabbed the quill in his right hand and tapped it on the table, Sergei and Eddie were still writing on the parchment, the tip of the quill rustling with each other, Joel made up his mind to take advantage of the dark moon and the high wind, and go to the stomping spot tonight.

The wait was always long and tormenting, and Joel had been thinking about tonight's step all day, and he was a little absent-minded when he was writing the outline of the history of magic.

As a result, Sergei found a lot of mistakes when he proofread Joel's copy in the evening, and it took Joel a long time to correct them.

At 8 p.m., as the students returned to the common room from their evening classes, Joel found his way out of the dormitory, out of the tower, into the auditorium, up the stairs, and around the second floor, finally finding Professor McGonagall's office in a hallway.

The office door was small, and Joel's eyes were fixed on the brass doorknob on the small wooden door.

Is this what you're trying to do?

He looked around to see that there was no one around, and reached out and touched the doorknob.

Yes, the ice is cold and cold, and it feels very good, and it is not made of ordinary brass as soon as you get started.

It was empty, and although Professor McGonagall's office and library were on the second floor of the castle, the library was at the end of another wide hallway, hundreds of meters away from the office.

Most of the students who came out of the library returned to the house common room, with Slytherin and Hufflepuff living underground, and Ravenclaw and Gryffindor resting in the tower.

At eight o'clock in the evening, no one would walk around the corridor on the second floor.

The question now was how he was going to remove the doorknob so that Professor McGonagall could not find the perpetrator.

He couldn't cast a spell now, he couldn't avoid Filch and the professor after curfew, and the hallway would only be less crowded at 8 p.m. when the library closed, so Joel was able to do it between 8 and 9:30 a.m.

And Professor McGonagall can't be kept in her office while committing the crime, or she'll find out.

Joel once heard Caitlyn say that although Professor McGonagall had a property in Hogsmeade, she would be living in the office since the beginning of the school year.

He teased the clues, and now there were a few conditions required to remove the doorknob from Professor McGonagall's office: between 8 and 9:30 p.m., lead Professor McGonagall out of the office, and then remove the doorknob without attracting attention.

The most critical aspect of the project was how to get Professor McGonagall out of the office...... His gaze wandered over the doorknob, and he found an extremely important point that he had previously overlooked.

Tools to remove doorknobs.

From the outside, the brass doorknob and the wooden door were tightly connected, and there were no screws in the Muggle world, presumably in some wonderful way to glue the two together.

Tools, what tools can be used to remove the doorknob from the door? Joel had been thinking about this on the way back to Ravenclaw Tower.

There are no hard and fast requirements for the means of removing the doorknob in this mandatory task......

That is, it can be hard unloaded with brute force.

Joel paused as he climbed the stairs, quickly called out the system panel, rummaged through the mall, and found a sledgehammer shining with golden light in a corner of the mall, which looked amazing.

He hurried to find out the specifics of the sledgehammer.

Invincible Sledgehammer: This object claims to be indestructible, but it doesn't seem to have much room for it.

Price: 30 points, this item does not require mana, and Muggles can use it freely.

System tip: Be careful of smashing your fingers when using!

30 Galleons? Joel was amused and quickened his steps to answer the question in front of the eagle-shaped knocker, pushed open the door and ran back to the dormitory.

Alan and Sergei were playing wizarding chess cross-legged on the bed, while Eddie pointed out the country and set aside a wad of parchment.

"You're back?" Eddie said hello.

"We're done with today's progress," Sergey said on his own initiative, "and a few of us are bored, so we just play two games of wizarding chess to exercise our brains." ”

Joel leaned over and looked at the game for a while before giving up, he couldn't quite understand.

He simply went to take a bath, and he was still looking forward to exchanging the sledgehammer in his heart.

In the bathroom, with the help of the sound of rushing water, Joel read out "Pipi Shrimp Krypton Gold System is invincible in the universe and is the first to use", and recharged 30 Galleons into the system.

He sped up the bath, hurriedly rinsed his body, crawled to the bed wrapped in his pajamas, wrapped the quilt, and rolled the whole person into a caterpillar.

"Hammer, hammer, I'm coming......," Joel rubbed his fingers and happily exchanged the indestructible hammer.

His hand sank, and a cold metal object pressed against his waist.

Joel poked his head into the quilt and saw that he was holding an iron hammer about twenty centimeters long in his hand, and his appearance was unpretentious, and he didn't have the dazzling golden light in the system mall at all.

What a profiteer......

Joel muttered, but the system never admitted that the real thing matched the photo, and even if it didn't, he didn't have anything to tell him.

No matter what, at least it's a tool to smash the handle.

Joel put the quilt over his head and began to think about how to turn the tiger away from the mountain and lure Professor McGonagall out.

As the night wore on, Joel didn't come up with any good ideas, but his eyelids grew heavier and heavier, and he fell asleep with the soft whispers of his three roommates.
