Hogwarts: Beyond the Dragon

Linglong traveled through time twice. For the first time, he traveled from the modern city to the world of immortality. It took him two to three hundred years to climb from a casual cultivator with mixed spiritual roots to become the number one person in the world of immortality. Then he got tired of it, tore open the cracks in space, burned up his cultivation, and just wanted to go back. The second time, he did put it back on - sort of. Wait, why does this world also have spiritual energy? Owls can actually deliver letters? Hogwarts. First grade. The five-hundred-year-old ancestor wants to learn the floating spell with the children. The sorting hat touched his head and there was silence for three full minutes. Voldemort still doesn't know that there is a being in this year's freshman class who is much more dangerous than him. A story about an ancient cultivator who traveled through time twice, each time more outrageous than the last.
