Within the swarm disaster mode, you may come across the Genius Society #55 Yu Qingtu. This event has multiple endings based on what you select, with two of the possible endings involving a battle against an elite enemy. The chance for these combat endings is random and is not guaranteed to appear, if you do however get a combat ending, simply leave the fight to have it count as a loss.

In reference to the video game "VA-11 Hall-A: Cyberpunk Bartender Action" in which you play as a bartender at VA-11 HALL-A, affectionately nicknamed "Valhalla."
