A total of 10 treasure chests, and the resources they yield are all good stuff. Topping the list was the Ghost's Treasure, with a guaranteed reward of five Soul Crystals (Complete). So-called guaranteed meant that no matter how unlucky you were, you could still open five Soul Crystals (Complete). If you were lucky, it could be 10, or even 20.

One Soul Crystal (Complete) was almost equivalent to one level of Blade Grandmaster. Therefore, Su Xiao was determined to get the Ghost's Treasure. If he could open 10 Soul Crystals (Complete), it would be a windfall.

However, it wasn't just Su Xiao who could exchange for the Ghost's Treasure. As long as they had enough Codex Merit, all contractors in the Nether World could exchange for it. Moreover, the top ten treasure chests each had only one, first come, first served.
