[HP Fanfiction + No Female Protagonist + Intelligence Flow + Early Behind-the-Scenes Development]

I woke up as Lysander Verrone of St. Waldemar's Orphanage.

An acceptance letter from Hogwarts? Great.

An ebony dragon heartstring wand? Not bad.

The Sorting Hat said I have Gryffindor courage burning within me? OK.

But why can I "see" things that others cannot see?

The restless dark vortex on Harry's forehead, the sticky parasitic black light on the back of Quirrell's head, the halo of holiness and curse intertwined in the unicorn's blood... and the suffocatingly huge magic field around the Philosopher's Stone!

Did Voldemort think that no one would know he was hiding under Quirrell's turban?

Is the protection level of the Philosopher's Stone perfect?

Snape's hatred was without reason?

In front of my eyes that can see through the source of magic, all secrets are exposed.

From creating his own invisibility spell to avoid the Marauder's Map, to analyzing the magical structure of the three-headed dog to resist the Killing Curse...

I quietly made arrangements behind the scenes and had a clear view of everything.

Dumbledore: This child always appears at the critical place and always gives a reasonable explanation.

Snape: ...his method of brewing potions has a disturbingly perfect insight, but unfortunately he is a stupid lion.

Harry: Lysander seems to know everything, he's practically superhuman.

When everyone was still doubting Snape or Quirrell,

I had already set my sights on the twisted black shadow behind Quirrell's head.

"Don't worry, Professor Voldemort..."

"For your resurrection ceremony, I will prepare a 'surprise' gift for you."

Han Bin travels to a strange world of assassins, becoming a bounty hunter on the hands of the assassin guild. Faced with a world of professional assassins chasing him, he unexpectedly awakens the [FPS cheat system]—at the start of the game, he selects "Auto-Aim," which automatically aims his bullets, making every shot deadly!

"Are you still practicing your marksmanship? Sorry, I never open my eyes when I shoot!"

"You won't play if there's a frame?"

"Fearless Warrior, Trench Warrior, Tank Hunter, Mother of All Bombs...Activate!"

"Italian Mafia? Slavic gangs? Japanese Yakuza... Sorry, you're all just on the sidelines!"

From slaughtering local killer forces to challenging the thirteen members of the High Table, from being hunted by underground gangs to being sieged by global killers, Han Bin, armed with a cheat, kills his way through the entire dark world.

As John Wick tightened his grip on his tactical pistol, Han Bin simply grinned.

"Mr. Wick, in this round, I'm the cheating monster."

(PS: The game is a mixture of the original work, the world view is slightly different, and there are some Dragon King elements in the early stage, please don’t click if you mind)

Uchiha Tendao pointed to the sky with one hand, looking calm and confident.

Uchiha Minghui clasped his hands together, his eyes shining.

"As expected of my most, most, most handsome Onii-chan!!"
