How to play Idle Underworld
Early development:
In the early stages of the game, resources are limited, and priority is given to the development of a faction to quickly accumulate basic resources.
For example, choosing a demon faction, focusing on increasing the number and level of upper demons, thereby producing a large number of lower demons, occupying a part of the map, and obtaining more basic resource points.
At the same time, actively explore the map, find easily accessible energy crystals and garbage resources, and prepare for future development.
Resource Management:
Pay close attention to the resource production situation of various factions, and allocate resources reasonably for unit upgrading, building construction, and research.
Don't spread resources across too many projects, focus on upgrading key units or buildings. For example, investing more resources into building upgrades that can quickly improve output efficiency can accelerate the speed of resource accumulation.

Reputation task planning:
Carefully study the requirements of reputation tasks and develop a plan to complete the tasks. Some tasks may require specific combinations of units or completion at specific locations, so prepare the corresponding conditions in advance.

Spells and Research Applications:
Once unlocking dark spells and laboratory research, fully utilize them to enhance strength.
Select appropriate spells and research directions based on current game requirements, such as choosing aggressive spells in difficult battles;
When resources are scarce, choose research projects that improve resource acquisition efficiency.
Post expansion:
In the later stages of the game, as resources and strength increase, multiple factions begin to develop, achieving resource complementarity and collaborative combat.
