The stereotypical old man of the sols, Yanlao's job is storage, maintaining New Kunlun's warehouse and the "Boundless Repository." He is obsessed with tradition and the safekeeping of artifacts, though not for their own sake but rather to maintain his own status. During his interactions with Yi, he is very annoyed at Yi's disrespect towards him despite his initial attempts to be formal. Throughout the conversations Yanlao begins to break down as Yi calls him out on his hypocricy.

Line Context and Tone: 

Line 1: Upon Yi reaching and re-activating the warehouse, Yanlao confronts Yi through a screen about his goals and tries to talk him out of his revenge mission. At this point in the game Yi is still unshaken in his mission to kill the nine other sols and return to Penglai, at the most having spared just Kuafu. At the same time, Yanlao still views himself as above Yi due to age, sounding condescending despite it being an attempt to peacefully talk with Yi.

Line 2: After fighting his way through more of the warehouse, Yi once again encounters Yanlao, this time in person. Despite his aggresive wording, Yanlao starts this line talking under his breath, though as he raises his voice it quickly becomes clear he's trying to stall Yi so he can activate Xingtian.

Line 3: After Yi defeats Xingtian, potentially interacts with Ji, and starts to tear through the Boundless Repository, he once again runs into Yanlao on a screen. Yi talks about how the warehouse could be put to better use, which is where this line takes place. Yanlao should be extremely angry for this as his true intentions become clear.
