When the same door starts appearing in your dreams, when the being behind the door starts whispering your name - this is not the beginning of a nightmare, it is an invitation.
Chen Guan soon discovered that the disappearance of his mentor, the taboo records about the "Dream Path" in ancient books, and the "collective nightmare" spreading in the city - hundreds of people dreamed of the same metal door being carved with runes by invisible hands - all pointed to the same buried name: Deep Space Lighthouse.
Tonight, how many people will carve a new mark on that door in their dreams?
When the doors are covered with scratches, will civilization soar or be doomed?
And Chen Guan, who holds the key in his hand, will be the first fire to ignite a new era, or... The final sacrifice for the glory of the past?
This is a secret war with the city as the chessboard and civilization as the bet. Here, knowledge is the most dangerous weapon and understanding is the most deadly curse. And when you finally understand the rules of the world, there is often no way out.
"We tried to touch the stars, but only awakened the abyss." - Deep Space Lighthouse·Last Diary
"This time, I don't light the lamp, I hold the fire." ——Chen Guan
