Hogwarts: Add Points to the Entry to Become the Strongest Wizard

As a time traveler to London, Sean's plan for his future has always been after awakening to the entry point adding system. Make some investments, earn a little money, become financially free, and travel around the world, but I didn't expect that I would suddenly receive an invitation to Hogwarts when I was 11 years old. Hermione: "I thought I was already very smart. It wasn't until I met Sean that I realized what true genius is." Luna: "Sean, come stay at my house this summer vacation." Cassandra: "Sean, teach me this spell, and I will grant you whatever you want." Qiu Zhang: "Sean, Christmas is here. Here are the chocolates I made for you." Voldemort: "How come this man can use dark magic better than me? Who is the Dark Lord?" Dumbledore: "This student will be the hope of Britain's wizarding world!"
