"Awakened Talent: One Certificate, Permanent Certification (Rank: SSS)"

"A spell that can be cast has been detected—Spring Breeze and Rain. Do you wish to learn it?"

When a science PhD travels to Hogwarts, he discovers that magic is just another form of energy—as long as there is a theory, it can be quantified, copied, and enhanced!

From analyzing the structure of wands to developing magic circuits and energy arrays, he ushered the wizarding world into the "era of technological magic."

Voldemort was sent to the research institute by him, and Dumbledore asked him to give a public lecture on "Magical Physics".

However, this was just the beginning—when he broke through the dimensional barrier, new worlds began to emerge:

In Middle-earth of The Lord of the Rings, he single-handedly suppressed Sauron;

On the continent of The Witcher, he combines magic and runes through alchemy;

In the Marvel Cinematic Universe, he even got Tony Stark to come and get inspiration from him;

After Harry Potter, he will eventually become the supreme god of magic in all the heavens and the myriad worlds!

Having been reborn into the world of Harry Potter, Raven only wants to live a happy and joyful life with his family and friends.

So Hogwarts gained a little badger who always acted on his whims.

Harry: Where's Raven? I want to see if he'd be willing to help.

Ron: He seems to have gone fishing in the Black Lake.

Harry: But I just checked the Black Lake, and it's not there!

Ron: Maybe he went to have hot pot with Hagrid? He always says that having a fish hot pot after swimming is very comforting.

......

Dumbledore: Raven, you should continue to create a few more spells so that you have a very good chance of getting a Merlin First Class before your fifth year.

Raven: But Professor, I don't want to continue. I've become more interested in alchemy and fishing lately.

Dumbledore: Your interests are very varied.

Raven: Yes, but I feel like fishing will be a long-term hobby of mine. Those damn fish just won't bite. I think I need to learn some new techniques to deal with them.

......

Grindelwald: You possess the immense talent of Raven, you...

Raven: Sorry, Mr. Grindelwald, I'm not really interested in the greater good.

Grindelwald: But war between wizards and Muggles is inevitable.

Raven: Let the people who should be worried about this worry about it. I'll bend over if the sky falls.

Grindelwald: ......

It became a demon-locking tower.

...The director?!

Lu Chen opened his eyes wide, somewhat stunned. What the heck?

"Give away a Grade One Qi and Blood Pill, and receive a ten-thousand-fold return, plus a Divine-grade Dragon Marrow Pill as a reward!"

"Gifted the mortal-rank martial skill Ice Soul Sword Technique, with a ten-thousand-fold return, and rewarded with the heaven-rank martial skill - Annihilation Fist!"

...

While others cultivate for ten years, he "licks" for a single day!

The school beauty wants a Qi and Blood Stone? Here you go!

The goddess needs cultivation techniques? Here you go!

The villain mocked him for being useless? He retaliated by overwhelming him with resources!

Lu Chen: "Flatter one person, and you'll enrich a region; flatter ten thousand, and you'll become a Martial God!"

...

Years later,

Lu Chen: I've met many women. Some called me a bastard, some called me shameless, and some called me a dog.

Without exception, they all became my women.

Bai Ye, who was reincarnated into a world full of various supernatural powers such as cursed spirits, demons, and Onmyoji, was severely damaged in a crisis he was involved in, and at that time he awakened the memory of his past life, and at that time the cheat also arrived. At the beginning, he obtained the power of chaos among the three ancient powers of Marvel. After the initial fusion of this power, he found that he seemed to be invincible in this world. However, when he received the second reward, he suddenly fell silent, because the second reward turned out to be the legendary Pear God Physique (rule level), and gradually various accidents appeared in his life. Yukinoshita Yukino: Bastard, you did it on purpose! Shinomiya Kaguya: I seriously suspect that you deliberately knocked me down, you scumbag with a head full of lust. Kasumigaoka Utaha: As expected, you are a hentai, junior!

He traveled through time and space and became a mutant of the same name and surname at Xavier Institute, awakening the strange X-gene, which turned out to be a creation of the system.

Whatever you think, the system will show it!

Li Haotian said he is invincible!

However, when he knew that this was the eve of the third battle, his heart suddenly trembled.

Even if he is not a fan of American comics, he still has some understanding of it through what he has seen and heard, and he knows very well how dangerous this world is.

It seems that besides the troublemaker who loves to mess around, oh no, it's Magneto, there are many wars about to break out in Gotham. Who are the opponents? Aliens! Evil gods!

That would be fine, but the terrifying Sentinel Plan has also been completed quietly!

Do you think that's the end? The Lord of the Dark Universe next door expressed his desire to visit here and bring with him a purple sweet potato that likes to do family planning for the entire universe.

How can we live like this?

Are you counting on rescue from the green giant in big shorts, the flying iron-shelled cool man and others?

But every time a rescue is carried out, a group of people will die!

"For safety reasons, my first system must be strong, and it would be best if I could get stronger even by lying in the sun!"

In the dilapidated hut of the London orphanage, Professor Snape's face was so somber it seemed to drip water.
