The Fourth Reward, Dragon Transformation

In the middle of the stone pillar, there were eleven blood-red square crystals, gleaming like rubies. Within their coagulated blood-like texture, a sense of nobility emanated, with golden threads branching out like tree branches, adding a touch of elegance.

Among the eleven crystals, one was larger than the rest, with denser golden threads spreading across it. Suppressing his emotions, Ji Chen picked up one of the smaller crystals.

[Advanced Crystal]

[Tier]: 5-star treasure

[Effect]: It can directly upgrade a military recruitment camp with a tier no higher than Tier 4 to Tier 4.

In this world, the tiers of military units were relatively fixed, and only a few methods could allow them to advance. The Advanced Crystal was one such method.

There were a total of ten of these Advanced Crystals, which meant that he could upgrade ten military recruitment camps to Tier 4. This was enough to elevate the majority of his military units to Tier 4!
