30 Hours Later, I Penetrated into Another World

I make a mistake while climbing a mountain, I fall into a secret realm, I pick up a skill, my practice goes awry, I meet a noble person, and I want to go home. When I returned home after 30,000 years, I found that only 30 hours had passed. Even though it was only a short 30 hours, the people who cared about me had been sad for that long. So you still have to become stronger and travel. (Oops, I'm not very good at writing introductions. Maybe if I write more content, I should be able to write the introduction)
