The Combined Battleship has many benefits; it conserves energy when flying together, and is more flexible in configuration during combat. However, it requires extremely high standards for the materials and craftsmanship of the warships.
After research, the Douluo Federation ultimately rejected the direction of Combined Battleships. The cost was too exorbitant, and the same materials could yield greater returns when used to manufacture mothership-level warships.
However, the Celestial Harmony Clan's warships turned out to be these costly Combined Battleships! No wonder all their warships have a uniform pattern; they can split off smaller warships by themselves.
