Lumine finally discovers her brother, Bai Luo, only to learn of his shocking rise through the ranks of power—ascending to Geo Emperor, becoming the first great sage of Buer, and ultimately securing a position as the 12th Fatui Harbinger. When questioned about these incredible achievements, Bai Luo dismisses them as mere coincidences, though Lumine remains unconvinced. Her skepticism deepens when Zhongli reveals a dark secret: Bai Luo stole Ningguang's prized Jade Chamber, explaining why the powerful figure trembles at the mere mention of his name. As the newly promoted Instructor-ranked 12th Fatui Harbinger, Bai Luo faces an impossible dilemma when the Tsarista, Queen of Snezhnaya, assigns him to Inazuma as her official envoy. Armed with knowledge from his time-traveling origins, Bai Luo knows the mission is a death sentence—General Raiden's wrath guarantees his demise. Yet refusing the Tsarista means certain death as well. Trapped between two impossible fates, Bai Luo employs an unconventional strategy: the ancient Teyvat tradition of fishing.
