Can You Cultivate Immortality While Lying Down?

I suddenly dreamed that I was mentally ill and wanted to take me to practice immortality? "Don't be like this, I'm just a student. I have parents, a girlfriend, and good brothers. This world is pretty good, and I don't want to leave them yet." "Who said cultivating immortals must leave your world?" "Then you have to not get married and have children, you can't do whatever you want, and you have to... Commit suicide!" After hearing this, the man laughed even louder: "Where did you hear this from?" "Follow me, just lie down."
