Like ordinary forces, almost all engage in businesses that can earn resources. Regardless of the size or strength of the force itself, they will more or less have some fixed industries in hand.
However, Tianyin Building can be said to have no fixed industries at all. If anything, they only have institutional buildings in various places. Tianyin Building has many branches in Kunling Heaven and also has branches in the Thunder Domain. Nevertheless, Tianyin Building has no cities of its own, and each of its branches is situated within cities controlled by other forces.
However, the speed at which Tianyin Building earns resources is equally astonishing. They mainly profit through selling intelligence. In this world, if Tianyin Building cannot obtain certain intelligence information, then no other force can likely get it either.
