The system's recognition of the Spear of the Dragon King brought the greatest benefit to Gu Hang, in that he gained a limit of two thousand genetic seeds for exchange.
Every battle group recognized by the system and obeying Gu Hang would provide him with an exchange limit of two thousand genetic seeds.
No matter how these seeds were created, whether through his exchanges or from existing interstellar warriors themselves, the total number of such seeds, once it reaches or exceeds two thousand, would mean Gu Hang could no longer exchange for new ones—although self-generation could exceed the limit.
The genetic seeds of the Spear of the Dragon King are named the 'Giant Dragon Legion Genetic Seeds.' They aren't inferior, but unlike the Phoenix which exhibited some differences from the parent group's Phoenix seeds and thereby got renamed.
After all, their military founding was not that long ago.
But that's not a bad thing; the Giant Dragon seeds are quite good.
