On his 11th birthday, Adam received a letter from Hogwarts and learned that he had come to the world of Harry Potter. He was also a wizard and was about to go to Hogwarts, the safest school in the world. What was even more surprising was that he and the famous savior were in the same class.
"I thought it was a life stream, but it turned out to be a survival stream"
Adam tried to transfer to another school, but it didn't work. Adam tried to go abroad, but he had no money. At this critical moment, Adam unlocked the sealed book of Cullo Reedo, and the cards in the book that were no different from his childhood memories were unexpectedly powerful!
"It's my turn now!"
"I have 54 cards here, can you kill me in seconds?"
"Is Fiendfyre considered fire? Well, why not? 》
《The male Philosopher's Stone was destroyed, I still have a female one》
《You'd better pray that this Clow Card is useful, otherwise I'll play the Power Card》
《Flower cards can only change into flowers, so they have no killing power? I'll give you a sea of ​​flowers~ What flowers? Chinese biting cabbage》

After the Battle of Hogwarts, according to our reporter's interview with the Death Eaters imprisoned in the new Azkaban, the other party claimed that Hogwarts was secretly researching weapons of mass destruction, which was called "Four Twos with Two Kings".
In response, the new Minister of Magic, Mr. Eugene, Professor Dumbledore of Hogwarts, and Mr. Adam, the youngest recipient of the Order of Merlin, First Class, issued a joint announcement, claiming that the speech was nothing more than the Death Eater's mental nonsense under Voldemort's long-term control of the Imperius Curse, and it was absolutely unreliable. The general public is advised to know.
