The Twin-Wand Archmage in HP

In his previous life, William was an ordinary person who died in an earthquake. He thought that in this life, he would attend an unremarkable school and remain an equally unremarkable nobody. He never expected to discover that he had transmigrated into the world of Harry Potter. His ancestors had been friends with the Four Founders of Hogwarts, and through incredible luck, he acquired the magic power of all Four Founders and a wand containing all the magic power of his ancestors. With the help of his System and his immense magical power, he rose to dominate the Wizarding World and began a journey to become the strongest person in the world.
