Travel through the world of Harry Potter and obtain the [Positive Energy Explosion Attribute System].

As long as you do positive things, the relevant people may drop attributes.

"I picked up 1000 Occlumency experience points, and my Occlumency skill level reached max. I got the achievement: Spell Mastery!"

"I picked up 500 points of Potions experience, and my Potions skill level was upgraded to level 5. I got the achievement: Potions Master!"

"I picked up 1000 points of physical experience, and my physical fitness increased to level 7. I got the achievement: Tear a dragon apart with my bare hands!"

...

Snape: "Are you an expert in potions? You should be the one to take the potions class from now on!"

Dumbledore: "You can master all spells at once, and you are so positive! You are the hope of the wizarding world!"

Voldemort: "We are all wizards. What do you mean by tearing the earth apart with your bare hands? Also, how come you are more proficient in dark magic than I am?"

Looking at the various black magic spells at the maximum level on his panel, Lynch was speechless.

Do positive things, why is the attribute explosion rate of black magic so high?

He looked at the admiring eyes of the people in the magic world:

"Although I'm very proficient in the dark arts, that doesn't prevent me from being the most positive wizard in the world. No one should object, right?"

A broken soul, having wandered for countless years in endless darkness, arrives at the warmest family in the wizarding world. He becomes the outcast of the Weasley family—Percy Weasley.

In this world where great power resides within itself, he will transform the magic wand in his hand into a long whip.

Evan has time-traveled once again.

His first time traveling was from Earth to the D&D world, where he went through trials and tribulations and became a sorcerer of the Universal School.

However, a fierce battle ended his second life.

When Evan opened his eyes again, he was surprised to find that he had once again traveled to a magical world that was both familiar and strange.

An owl flapped its wings and flew swiftly, delivering his Hogwarts acceptance letter, but the timeline he arrived in was 1971.

In 1971, a turbulent era, the Demon King was stirring, the Phoenix perched high in the castle, and the towers of Nurmengard remained tightly shut.

And those future heroes—Lupin, Sirius, James, Lily, Snape… at this moment, they are just innocent teenagers, unknowingly walking into the vortex of fate.

This is a glorious era, though not detailed in the original work, it is equally magnificent and filled with brilliant stars.

However, for Evan at this moment, the first thing he needs to solve is how to restore his spellcasting ability in this world without a magic network and with scarce magic power.

Or perhaps, he could go even further, relying on more advanced magical research concepts, gathering a group of intelligent and powerful companions, and launching a magical revolution that would change the entire magical world.

In any case, the times are waiting for Evan's actions.

-----------------

The timeline is set in 1971, in the same year as Sirius Black, Lupin, and Snape. The protagonist has mastered the spell system of D&D, has no system, breaks up the original pairings, is slow-paced, not mindless, and will seriously consider the plot.

When the raven opened its third eye, the entire magical world began to tremble.

When the Sorting Hat put him into Ravenclaw,

When Dumbledore discovered that the castle had been whispering secrets to him for thousands of years,

When Grindelwald praised him,

When Voldemort wanted him to join,

Everyone was shocked to realize that the world of magic was about to change and a new era was coming.

False druids: follow the way of nature, master the magic of nature and the form of the wilderness, and gain the ability to transform into wilderness creatures and control the elements. The real druids, however, look further: the flow of planes, the birth and death of the world, the upside-down galaxy, and even the endless echoes of the multiverse, are all the pulse of nature. Nature is not just mountains, rivers, lakes and seas, but existence itself, the breath of law, and the rhythm of time. I am nature, and nature is me. The flow of all things is in the mind. Okay, no more pretending. This is a druid who traveled to the continent of Faerun, mastered the transformation into the Star-Forging Dragon King, specialized in the Society of the Stars, controlled the power of nature and the secrets of the stars, could crush planets at will, and mastered the birth and death of the universe.

I've been transported to Hawkins, the town from Stranger Things, and become Will's brother, Jonathan Byers. This America is too dangerous; horror stories unfold everywhere, and the sweet air is thick with evil. The neighboring town is Silent Hill, with a street called Oak Street, home to the Shining Hotel. I've heard there's a cabin in the woods beyond town. Legend has it that deep in the forest lies a fairytale town inhabited by vampires and young wolves, while Jason and Voldemort lurk outside. From time to time, demons from hell invade the world, aliens are always causing trouble on Independence Day, and Thanos, the head of the Space Office, is willing to snap his fingers—if you're unlucky, you'll be vaporized to dust. Luckily, I have a Dungeon Fighter Online (DNF) game system with me, allowing me to become a professional exorcist and form an exorcist alliance. I've gathered Constantine, Johnny Depp, Van Helsing, Nick Wilde, and the Ancient One. Everyone, don't fight over this monster; let me kill it! I'm super strong… If you, fellow readers, find "This Stranger Things is a Bit Cold" enjoyable, please don't forget to recommend it to your friends on QQ groups and Weibo!

Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

Words are like silk, weaving the warp and weft of stories; stories are like rivers, settling the pebbles of knowledge; knowledge is like fire, forging the stars of wisdom; and in the folds of time, the ancient light of civilization shines forth.

Forming a bond with a woman will earn you rewards; forming a bond with a noble woman will earn you even more rewards.

Having experienced two consecutive time travels, Li Zhihui finally awakened his system, but he ended up with an unorthodox one.

"So, it's really not that I'm promiscuous, it's just something that can't be helped."
