Surveying his empty Immortal Guild City, Chu You headed to the teleportation formation and from there, teleported to the capital of Yan Kingdom.
Ruminating on his recent actions, Chu You believed that it would be considerably difficult at the current state of the game for players to acquire flight ability. Even if they got hold of Flying Wings, they could not get into Immortal Guild City. A death shield given by the ruling fortress, protecting the city against players, would stop them. If the ruling fortress was gone, the guild would be left exposed to their enemies; a troublesome situation for the small 'Immortal'Guild.
Therefore, Yan Kingdom's ruling fortress must never be lost, relieving one of Chu You's worries.
Unbeknownst to Chu You, not long after he teleported away, a girl appeared outside the City Above the Clouds, specifically outside the death shield. This girl was Jiucaier.
