This is the time Yu Liang has left.
When you add it up, the cost of completing this Strange Story is really quite high; Yu Liang hardly had any time to do anything else in those eighteen hours.
Adding in the six hours lost downstairs due to the encounter with Ghost Man, Yu Liang had wasted a day and a half in this building.
A day and a half, and he hadn't even left this building, while there are countless such buildings in Cyber City.
A sense of urgency began to grow in Yu Liang's heart as he gradually realized the disgusting aspect of this Instance.
Viewing time.
Exploration takes time, finding new origins of Ghost Man takes time, being dragged into an illusory realm by a Ghost Man deducts time, and accidentally encountering a subline Strange Story can consume a lot of time.
The design of such an Instance is really too cruel; who knows who came up with this setting.
