Hogwarts: The Savior's Strong Cousin

Harry Potter felt very strange. Ever since that rainy day when a bolt of lightning struck his cousin's bedroom, the cousin who once liked to beat him seemed to have changed his temper.

Dudley Dursley, who was thick-skinned and tough, was not injured. He just blew out a puff of black smoke and sat on the ground for half an hour. When the ambulance came and wanted to take him away, Dudley waved his hand and stood up vigorously. The worried aunt and uncle were relieved to see that their big son was fine. Of course, they couldn't help but sneer at the curious Harry.

The next morning, when Harry opened the door of the storage room, he happened to see Dudley coming in panting and carrying a towel.

"Oh, Harry, good morning!"

"It's a nice day today, the air is fresh, isn't it?"

"Listen, I'm sorry for what happened before, and I swear on the Dursley name that I won't bully you again."

She bowed to Harry very sincerely. The stunned Harry didn't react at all. Even his aunt's sarcastic remarks disappeared completely in his ears.

Is this still the same Dudley who enjoys beating himself every day?

Harry's doubts did not last long. At the breakfast table, Dudley repeated this sentence very solemnly, which immediately shocked Vernon and Petunia. However, after all, they loved their son, and when Dudley threatened his parents with a hunger strike, the Dursleys finally compromised.

"Alright! Boy!"

Uncle Vernon gritted his teeth as he picked up a hammer and removed the lock on the door of the storage room under the stairs. Dudley behind him smiled with satisfaction.

Harry Potter fell into deep thought.

He began to look forward to another rainstorm, when two more lightning bolts would strike his uncle and aunt as well.

Dudley stretched and he could see Harry's complicated look. He turned around and sighed quietly.

An electronic sound that only he could hear soon sounded.

"Successfully integrate into the Harry Potter world, reward: giant blood."

"Change Harry's childhood. Reward: Boxing mastery."

He was not the original Dudley Dursley. In his previous life's words, he was a "time traveler". Dudley didn't care much about his previous life's name. After all, in the British Isles of this world, it was easy to be exposed with an oriental name.

Fortunately, Dudley had read Harry Potter, so he recognized the little boy with glasses at a glance. Dudley in his previous life was still a little indignant about Harry's childhood, so when the inexplicable system issued this task, he immediately chose to make friends with Harry.

After all, children's minds are easy to change. At least, Harry, who had not accepted the kindness of his relatives for a long time, accepted his cousin.

"But what are these rewards?"

"What about magic? I want to learn magic!"

"Mastery in boxing? Can I defeat Voldemort if I learn this?"

Hearing Dudley's faint complaints, Harry frowned in the storage room.

What magic?

Subconsciously lifting his hair and touching the scar on his forehead, Harry instinctively felt that this scar seemed to be deeply connected to the "magic" his cousin mentioned.

As the days passed, Dudley, who changed the worldline, cleverly concealed Harry's Parseltongue when he went to the zoo with his family. Although the Burmese anaconda still broke through the window and escaped, this did not make Harry suffer more ill will from the Dursleys. At most, the London police were overwhelmed by a large number of calls for the police that day.

In the blink of an eye, it was the morning when I was supposed to receive the admission letter.

"call."

Dudley, whose body had become exceptionally sturdy and strong, and who no longer looked fat, put down the dumbbells in his hand and wiped the sweat off his face.

The giant bloodline awarded by the system made Dudley, who was 11 years old, have an exaggerated height of 1.9 meters. At Dudley's strong request, the system reluctantly added an additional ability to adjust his height at will, so that Dudley's height did not become an exaggerated degree. However, despite this, such a height still stands out among his peers.

The original fat and fat also turned into bulging muscles after day-to-day exercise. Vernon and Petunia questioned Dudley's way of changing his appetite. After all, it was not difficult to see the simple aesthetics of the Dursleys from Vernon's belly. However, under the tried and tested hunger strike protest, Petunia could only hold her nose and strictly follow Dudley's recipes to make three meals.

"Cousin, look... this is a letter for me."

A cautious voice came, and Dudley turned his head to see Harry holding a stack of stationery and showing him a letter with a smile. The content of the letter was very familiar to Dudley.

"To Mr. Harry Potter, the closet under the stairs, 4 Privet Drive, Little Whinging, Surrey."

As for the side with the wax seal, there was no doubt that it was the Hogwarts emblem that Dudley had been dreaming about.

After taking a few steps into the room and seeing that his uncle and aunt were not there, Harry quickly sat on Dudley's bed and handed the letter to his cousin with a smile.

After spending some time together, Harry and Dudley have become very close, to the point where they can talk about anything. Therefore, when Harry has a secret, he will only share it with his "dear" cousin.

After stroking his chin and thinking for a while, Dudley looked at Harry seriously.

"You must listen carefully to what I say next."

"I will pretend to expose this letter, and then Vernon will definitely tear it up. In the next few days, there will be an endless stream of owls delivering letters - of course, you have to pretend to be completely unaware."

"After a few days, they will take us to a reef in the sea with a dilapidated wooden house on it."

"There, you will know the true contents of the letter."

Dudley stopped, looked at Harry who looked puzzled, and snapped his fingers.

"Hey, do you understand?"

Harry nodded quickly. He trusted Dudley very much now. After all, he was his only friend and relative in the Dursley house.

After taking a look at Harry who had no idea what was going on, Dudley curled his lips and returned the letter to Harry.

"I have no interest in Smelting Middle School, Harry, do you mind if I become your classmate?"

As Harry blankly agreed, things happened exactly as Dudley described.

Whether it was the increasing number of owls, the increasing amount of scraps of paper in the house, or his inexplicable move from the storage room to the second-floor bedroom, all of these made Harry firm in his belief - it was never a wrong thing to listen to his cousin!

In the midst of the storm, there was a loud banging on the door outside the small house on the reef.

Harry, who was counting down to his birthday, and Dudley, who hadn't slept at all, smiled at the same time.

"Hogwarts, I'm here!"

Dudley sighed inwardly as a huge figure appeared behind the collapsed door.
