The dream notebook's mutation _1

However, just as Holy Dragon city's development was progressing at a tremendous pace, an unexpected situation occurred again.

Another busy day had ended. Tang Zhen returned to his room and flipped through the notes that the dream city Lord had given him before he fell asleep.

What Tang Zhen didn't know was that after he fell asleep, the Black Diary that would update its contents from time to time suddenly emitted a fluorescent light. A special energy spread out from the diary and slowly enveloped the entire room.

Tang Zhen did not know how long he had slept in a drowsy state. Suddenly, he heard someone whispering beside his ear. That voice was soft and it seemed as though they had deliberately lowered their voices so that no one else could hear them.

A thread of vigilance rose in Tang Zhen's heart. He quietly opened his eyes, only to discover that his surroundings were completely dark. It was as if he was in a room without any lights.
