"Give me your heart, okay?"

"The Lord of the Great Country!"

"Mangekyo Sharingan! Uchiha! Mizukage, shouldn't you explain?"

Wait? What's that thing in his hand? A heart? It can't be mine, can it?

"I don't know any Uchiha, I only know the divine flame that blocked the lightning sword for me."

"Remember, the flame of the Divine Flame

It is boiling with passion to protect what I love."

Multiple female protagonists cultivate and travel through Douluo, drawing two diametrically opposed abilities from the system. From then on, the right hand "Excellent" modifies the goddess's memory, changing her appearance, absorbing damage, and optimizing her spirit. The left hand "Degrades" and transfers damage. This begins a journey of interdimensional thieves.

Are life energy and Nen abilities the same? Does Enhancement only enhance the body? Does Transmutation only change matter? Does Manipulation only manipulate life itself? ...Reincarnated as an infant, Gao Tianming wants to understand the essence of all this. (This book is a slow burn, not an invincible or system-based story; it's a story that grows gradually.) (A new, fledgling book; please don't be offended, just scroll away.)

[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."
