Is the difficulty the most mysterious?
Don't take the golden elixir for granted
If you don't meet a great person to tell you the secret, your mouth will be dry and your mouth will be dry with empty words.
If a person cultivates Taoism and becomes an immortal, in modern society where science has disenchanted him, it is tantamount to telling others that he is a fool. Of course, I will not reveal this obvious "secret" easily. Persuading people to practice Taoism is a thankless task. Without self-awareness and self-experience, it will only harm others and yourself.
Why would I believe such a seemingly ridiculous thing? Everything starts from ten years ago, when I was in high school. That was the first time I met the owner of the "Ancient Mirror"...
