With the arrival of a strange dream, people find that they can reach another world through dreams. This is a world full of mysteries and disorder. People call this world a nightmare.
It is not compulsory to simply choose to accept the challenges from the new world. Some people choose a peaceful world and stay away from disputes; but there are also people who think this is an opportunity and choose the new world. They are called "Explorers"
Chen Xi's memory of the past was very vague. He entered the nightmare by chance, and then found that he seemed to be able to hear sounds that other [explorers] could not hear. He once wondered if he had a mental illness, but he soon discovered that these sounds were real.
Determination: longing for it, moving forward without hesitation
