Chapter 83 - 17: Summer Harvest
Roman had been in Sige Town for 100 days.
He stayed at the Wood Factory for several days and finally "Manufacturing" Skill had been leveled up.

[Level 2 Manufacturing: 0\380]
[Milestone Unlock: Handicraft]
[Handicraft: Obtain 500 original stones]
Compared to other skills, this one was far more complicated and vast. Roman felt a torrent of knowledge continuously bursting forth from his mind.

Nine Life Skills were like nine different seeds. By drawing Experience Points, they would root and sprout, intertwining and overlapping during their growth, and eventually become a complete and elaborate technology tree with abundant branches and deep roots.
Roman vaguely knew what kind of effects each skill level-up would bring and what changes multiple skills working together could bring.
