Dare to love me and let go. If you let me down, I will make everything go to zero. What does the above mean?

It means that he can let go, no matter how deep his love is, if you are sorry for him and fail to live up to his love, he will not have a trace of nostalgia, and let everything go back to the starting point as if it had never happened. Few people can let go, which is almost impossible, because people have feelings in their hearts, and animals have feelings. What's more, people who have really loved are in their hearts, but they have never really loved. How can people or things that have been in their hearts be forgotten? They will never forget them, just don't want to mention them again. Really loving someone who lets you down is not the same as. Does this person have no heart? How can a person without a heart love?
