Harry Potter:

Dementors are evil magical creatures that have no facial features and can only distinguish living people by smell and the emotions floating in the air.

Wherever they go, all happiness will disappear, leaving only the deepest fear in people's hearts.

Legend has it that under the hood of the Dementor there is a face that can devour souls...

"That's the theory."

Cohen Norton did not deny this.

"But this doesn't affect my desire to be a good person. No, it's weird."

As he said that, Cohen licked the lollipop in his hand and turned a blind eye to the child next to him who was crying because the candy Cohen's brother gave him suddenly disappeared.

[Ding! Goodwill value +1, sin value +1]

[Note: Giving candy first and then snatching it is immoral and you will be condemned by your conscience]

"What is this, Tom Riddle's diary? There's a soul in it, take a sip."

"What is this, Slytherin's locket? Pry it open and take a sip like an oyster."

"What is this, Hufflepuff's cup? Add some milk tea and take a sip."

...

"What is this, Harry Potter? You smell good, bro, sip--"

"Cohen, don't come over here!"

"I'm here to decorate! What are you doing!"

Kesenhis looked at the weirdo who suddenly appeared in his workplace and tried to attack his personal safety with a strange wooden stick, and scolded him by saying something like magic and keeping secrets.

He also used the obsidian block that suddenly appeared in his hand to instantly release a huge obsidian pillar for defense.

"Bold! You still say you don't know magic!"

Traveling through the world of Harry Potter, he also got the block gold finger in the game [My World]. Just when he knocked out the weirdo who suddenly came and went crazy and was about to make a name for himself in the decoration industry, he saw the white-bearded old man in front of him.

"What do you mean... hire me to be the alchemy professor of Hogwarts?"

Also, what is alchemy?

In the first year of coming to Hogwarts, he carefully disguised himself as an alchemy professor with some basic blocks.

In the third year of coming to Hogwarts, he gradually got better and fought against the Dementors with withering.

In his seventh year at Hogwarts, holding the command cube, Kesenhis raised his middle finger to the boiled egg in front of him.

"Watch out, I will demonstrate the framework of how the world works next!"
