One last thing Lex did before returning to the Crystal realm was add the Patisserie. Since it had been brought to his attention by his prophecy, he would not ignore it. Like the Recovery room, meditation room and such, the Patisserie was a standard Inn service, so not only could it be repeatedly be put across the Inn. As soon as he redeemed the building, he first upgraded it to the fourth level, which was in tandem with his authority level.
Some buildings, such as the Recovery room, had been upgraded beyond his authority level using various cheats, but in general that was not a good thing as it put additional pressure on the system. Lex wasn't exactly sure why something as simple as a service building would affect the system's functionality, but then again, each of the services was quite magical.
It had been a long time since he himself had visited the Training room, but it was quite popular at the Inn amongst many cultivators, so it must be good.
