B City, the headquarters of the Business Alliance.
Mu You and Lin Xue, along with Little Ya, followed Lin Hai to the basement of the building, because one of the Business Alliance's 'Doors' was stored here.
Mu You had just discussed with the other City Lords and they all decided to first go to the Star Spirit World to protect their respective Sky Cities.
Moreover, this matter has also been notified to all domestic and foreign powers that own a 'Door', and at this moment, a large number of elite players have been mobilized, pouring into the Star Spirit World through the Doors, participating in the defense of Sky City.
Since Mu You's own Door had been used a few days ago and couldn't be opened for the time being, they could only temporarily borrow the Business Alliance's Door.
Mu You was not new to this place. Back when version 1.0 was just updated, he had already used the Business Alliance's Door.
