Dimensional Store and the Infinite Crucible! I

For upgrading and fusing Silver Units into Gold, he needed 50,000 to max each unit for a total of 100,000 Silver Upgrade Crystals. To fully max a single unit and be able to fuse it with another, 200,000 Gold Upgrade Crystals were required to do so!

It was an obscene number as it meant he had to collect 400,000 Gold Upgrade Crystals to even taste his first DIAMOND Unit.

But Noah was unhindered by this large number as he delved into the 56th floor after checking the rewards and replenishing all his units and himself with potions. His eyes also lingered on the 25 Random Gold Unit Shards that he just needed 75 more of to summon a Gold Unit, his drive to very quickly clear the upper floors of the Tower of Champions blazing ever higher!
