Chapter 62: Blacksmith (Part 2)
After the bath, the water was simply poured out, eliminating the need to carry it out. After washing up, Clara began Mateo's training. They started by watching a documentary about blacksmithing, and Clara was moved to tears by the end. The documentary portrayed ancient humans as pitiable, but in Clara's eyes, that era was quite self-sufficient. That was the era she lived in when she was a child.
Clara also watched a documentary about farming, and with the commentary, she learned that in the 1960s and 1970s, people lived an almost hellish life. The documentary then jumped to the future, showing Clara that, after a long time, humans would eat highly nutritious plants and vegetables grown on extraterrestrial planets. These plants would be cultivated in nutrient solutions by robots, eliminating the need for land.
