Ch. 487Northward
A'liuer visited Gu Shen with the North Continent Empress's request that he investigate a coming crisis at North Continent Fortress, whose resolution was tied to Nagano and Clear Tomb Cemetery. Gu Shen agreed to travel north to seek clues about his missing teacher and fellow disciples, and began asking about the records of Source Energy Airships.
- A'liuer secretly spoke with Gu Shen in Spring Rain Temple and told him that the Empress believed Gu Changzhi had left a letter for her, which Gu Shen insisted on delivering personally.
- A'liuer explained that Gu Changzhi and the Empress had once fought together, and hinted that Gu Changzhi had left other secrets with trustworthy people.
- A'liuer revealed that the Empress was in poor condition and had foreseen a possible assault on North Continent Fortress, with the key to resolving it connected to Nagano and Clear Tomb Cemetery.
- Gu Shen considered the Empress's warning alongside the year-long disappearance of his teacher, Senior Brother, and Senior Sister inside Piyue City Fortress, and agreed to investigate in the North Continent.
- Gu Shen and A'liuer met a Source Energy Airship beyond Nagano's northern border, and Gu Shen asked whether each airship had a serial number and travel record.
