Hogwarts: My Cultivation System Got Crossed with Another Channel!

[Harry Potter Fanfiction] [Cultivation System] [System Crossed Wires] [Hilarious Contrast] [爽文]

[Everything Is Made Up!!!]

Lin En transmigrates into the world of Harry Potter and waits impatiently for eleven years before finally receiving his Hogwarts acceptance letter.

Who could have guessed that the [Myriad Worlds Renegade Immortal Cultivation Comeback System] he awakens would have a serious malfunction?

Looking at the oddly dressed wizards in the Leaky Cauldron, the System lets out a piercing shriek:

[Warning! The Host possesses a fake spirit root and has strayed into a demonic cultivator marketplace in the Southern Border. Beware of demonic cultivators trying to seize your body!]

From then on, the entire Wizarding World goes completely off the rails:

The moment the Sorting Hat touches his head, the System warns: [Detected a thousand-year-old artifact spirit attempting to possess you. Activate a spirit-soul counterstrike?]

Lin En strikes back with a jolt. The Sorting Hat shuts down on the spot, cries, "This boy must not be allowed to live!" and dumps him in Slytherin.

In Potions Class, Snape sneers and tells him to brew a Cure for Boils.

System: [A flawed first-grade Foundation Establishment Pill recipe? I have automatically deduced a perfect path of alchemy for the Host!]

When Lin En uses Tai Chi and the Eight Trigrams to work up a batch of golden pills, fragrant and swirling with pill patterns, Snape's greasy hair instantly stands on end!

Then, one night, deep in the Forbidden Forest, Voldemort, in a remnant-soul state and sucking on Unicorn Blood, turns back with a sneer.

Lin En looks at the System panel: [Third-level Qi Refining demonic cultivator remnant soul. Killing it may yield a hundred spirit stones.]

He silently pulls a "flying broom" covered in thunder talismans from beneath his wizard's robes:

"Heh heh heh, fellow cultivator, come join me for a chat inside my Human Emperor Banner!"
