Ye Yun transmigrates into The Outcast and gets bound to a sign-in System. At Mount Longhu's Luotian Grand Ceremony, he signs in at the entrance to the Celestial Master Mansion and obtains a fragment of the Heaven Communicating Talisman Art. In a courtyard deep in Beijing's hutongs, he signs in at Wang Ye's home and grasps the basics of Feng Hou Qimen. Ma Xianhong's Divine Machine Hundred Refinements at Biyou Village, the deadly poison miasma of the Tang Clan's Dan Shi, the divine tree on Nason Island... they all become sign-in locations. Feng Baobao tilts her head and tells him, “You smell like hot pot broth that's gone bad.” Ye Yun replies, “...Sister Baobao, that's the fragrance of traveling through time and space.” When Wu Gensheng's secret is revealed, Ye Yun stands at the center of every truth. The System's prompt rings out one final time: “Ultimate sign-in complete. Choose: return to your original world, or stay here?”
