It's Broken, I'm Dominated by My Heart

I had a dream. I saw my heart being eaten, and I was afraid that I would become disabled. I was still young and I didn't want to die, so I ran as hard as I could until I saw a ray of flame. When I woke up in the hospital and felt my strong heartbeat, I knew it was a dream! "An asteroid is flying towards the Earth and is expected to arrive in a year. Scientists have detected fluctuations of life on it." "There was a thunderstorm in Antarctica, and some people saw immortals flying with swords in the thunder and lightning, but experts explained that this was just a natural phenomenon." "A week ago, Zan attacked a school..." Listening to the broadcast on TV, I was quite worried. When the spiritual energy revived, everyone else was flying with their swords, and I was the only one running with my legs. So, I sat down cross-legged and slowly closed my eyes. After a long time, I opened my eyes and tilted my head. No one taught me how to cultivate immortality?
