Tree Monster Territory's integration had an immediate impact.
It began by supplying a large amount of lumber to other regions of the Alliance at relatively low internal prices.
Wood is a very important raw material. Even without considering its use as fuel, it is an indispensable part of construction, vehicles, and various types of equipment; not to mention household items like basins, buckets, boxes, and cabinets, which are mainly made of wood.
This drove the boom of the carpentry industry and also improved the tool quality of various cities.
Ships that were modified for use as ice storage were bringing ironware, textiles, medicines, and all sorts of food into Tree Monster Territory, and then transported fruits and fish back, once again expanding the residents' menu of the Development Alliance.
Food diversification is also a fundamental safeguard for human health.
