Synopsis

Jin Cheon Hee, the young protagonist, implements a series of surprisingly effective solutions to help his ailing master, including a furnace and glass windows to improve heating and sunlight exposure. These novel ideas, seemingly inspired by Western designs but enhanced, drastically alleviate the master's symptoms, leading to improved health and deeper sleep. Impressed by Jin Cheon Hee's abilities, the master contemplates making him his successor, even pondering the adoption process and its potential implications while others watch their interactions with growing admiration and suspicion, noticing his deep attachment to the young boy. The chapter ends with a weighty consideration of the master's words about the young man using the name 'Jaegal' at some point in the future, a subtle indication of his eventual successor.
