As a survivor of the war, Roger is learning magic just to survive.

Nicolas Flamel: "Then I will teach you how to make the Philosopher's Stone and brew the Elixir of Life, okay?"

"No, no, it's called immortality, but after hundreds of years, the body will decay and suffer endlessly. Can this be called immortality?" Roger shook his head.

Voldemort: "I will teach you the method of Horcruxes, which can be divided into seven parts and reborn after death. How about it?"

"If you don't want to learn, you will be incomplete if your soul is cut. Even if you seem to be reborn, the Ship of Theseus, which has lost its continuity, is no longer the me I once was?"

Dumbledore: "Death is not the end, but a new great adventure. I will teach you..."

Before he finished speaking, Roger interrupted: "When there is still hope, choosing death is nothing more than admitting defeat and escaping from this world. Without hope, how is it different from real death? Don't learn!"

Grindelwald: "I will teach you the art of prophecy, anticipate the enemy's moves, grasp the tide of the times, lead wizards to greatness again, and then gather the power of all wizards to support you and prolong your life. How about it?"

Roger, who is also a prophet like him, thought about it seriously, and finally shook his head. "Just as I am now above this era, there are always talented people in every generation, and the world is vast and boundless. No matter how powerful I am, there will always be more powerful beings standing in front of me in the future. No one is always invincible, and no one is really invincible. Being too deeply involved with all living beings is not the way to eternity."

Rejecting the teachings of the last elder, Roger Virgil looked into the starry sky: "...There is no way in the world, it seems that I can only open one myself."

"Robin, a model citizen, is transported to a magical world, inheriting the bloodline of the Eastern Phoenix from the start! After enrolling at Hogwarts, with his extraordinary talent and the blessing of the Phoenix bloodline, he gradually rises to the pinnacle of the wizarding world, becoming an existence surpassing even the god of magic, Merlin!"

Traveling to the world of Harry Potter, Ivan Vesemir became the heir of a pure-blood family.

Adhering to the central idea of "If you can survive, you will survive", Ivan handed over the Horcrux he got to Dumbledore, detoured when he met Harry Potter on the road, lowered his grades in the exam to make the professor ignore him, take a step back and find a way out;

Arm yourself with alchemy, study black magic and learn about your enemies.

And then, he was inexplicably targeted by the boss...

"What? Why can I achieve what I am today? Ah... It's embarrassing to say, they won't let me go on, so I can only find a way to kill them all."
