01
Give the bench a usable space
Release-day footage prepares an indoor space for the Research Bench. It then looks at Wood Processing as an early project. This demonstrates an actual preparation sequence without proving every current placement rule. If the bench cannot be used, its displayed requirements matter before an assumed optimal research order.
02
A documented early chain
The researched walkthrough connects wood processing with planks and a Goddess Statue. That makes it a useful example of construction enabling character progression. A written guide also recommends this early branch before choosing later work around equipment or supply needs. The recommendation is a strategy example, not an official mandatory sequence.
03
Unlocking and finishing
The book guide separates access to a research project from the labor needed to finish it. A bench alone therefore does not establish that all requirements have been satisfied. Exact book costs, prerequisites and the full current tree were not verified. Treat a universal best order or a complete cost chart as 待确认.
04
Tech Book
Research Books are reported to unlock research, while workers must still complete the research work. Guaranteed book sources and the official equivalence of Tech Book and Research Book remain 待确认.
Acquisition examples are not guarantees
That guide records a book from a floor-one chest in one run. An older Wiki also lists chests, supply carts, bookshelves and merchants. Neither proves a guaranteed current source or a fixed inventory. A single successful chest should not become a promise that every new expedition will provide a book there.
Names and spending priorities
Legacy footage explicitly picks up a Tech Book and connects it with research. The research did not find an official localization mapping between that label and Research Book. Exact project costs and a universal best spending order were also not established. Keep the names recognizable while checking the project requirements in the version being played.
