In 2035, three years after the global phenomenon-level holographic online game "Deep Space Fantasy" was launched, a mysterious copy [Data Forbidden Zone] suddenly appeared. Players find that those who clear the level can gain the authority to rewrite reality, but those who fail will be permanently erased from the game. The protagonist Ye Ran, as the only abnormal account marked as "Zero" by the system, is forced to get involved in this survival game where reality and fiction are intertwined.
