Wang Xuan indeed had reason to be excited.
As the game master, the administrator, and the controller of the story, his biggest headache was his near-total lack of control over the game's storyline.
All story developments were completely left to the original script provided to the system and the system's automatic correction function.
With the system's oversight, the story should have been able to follow its predetermined course.
However, the influx of a significant number of players brought countless uncertainties to the game, which, while generating astonishing revenue for the game company, also made controlling the overall narrative increasingly difficult.
The more players gathered, the less controllable the situation became, especially in such grand battles between the Alliance and the Horde, where players, nearly one-third among tens of thousands, especially Adventurers acting as a sort of 'fourth calamity,' were a disaster for narrative control.
