At the end of the invitation, there's a countdown, with time matching the clock tower in the public area plaza.
When Wu Chang received the invitation, there were exactly ten days remaining.
He looked at the part in the invitation regarding the initial exploration rights, which mentioned that he attained these rights due to his outstanding performance in the qualification instance.
The requirement to qualify for the World Dungeon is completing the qualification instance and having an exploration degree within the top ten thousand among all players who participated in the qualification instance.
From the content of the invitation, the ranking not only selects who can enter the World Dungeon but also grants players corresponding advantages based on their rank.
For instance, being ranked first allows him to enter the World Dungeon 36 hours in advance to familiarize himself with the dungeon world.
