Inexplicably, I Started Practicing Spiritual Practice

I arrived at a mountain inexplicably. I practiced for two and a half years and couldn't walk out. I also picked up a little girl. I don't know why I killed the sword ghost. I became a holy son in a daze. I was arranged to go on a blind date just when I wanted to practice. What kind of holy son is the holy son who is in debt? What is the purpose of practicing immortality? Who is using me to watch Taoism? Why are there so many weird things? What is the wonder of the Taoist road? Where is the protagonist Lin Jiang's spiritual path going?
