I Went Down the Mountain After Secretly Learning Martial Arts in a Taoist Temple

Master said that going down the mountain is for experience. But I think he just thinks I eat too much. Before leaving, he gave me three magical artifacts: a cracked mirror, a bell that didn't ring, and a broken book. He said this is the inheritance of his master. I feel like this is him clearing out his inventory. But it doesn't matter, anyway, what I learned secretly in the mountains in the past fifteen years is enough.
