Angor moved closer to a wizard to check what was written on the contract.
And he immediately felt his back drenched in cold sweat.
The entire contract was a heartless agreement that could be summarized by two simple words, which happened to be the "boost" mentioned by Lawson.
Blood sacrifice.
It was like how Sunders herded a group of phantom beasts into the construction site of the gravity garden. Once the garden was made, these beasts used their blood and flesh as part of the building materials.
The same thing would happen again in the purification garden.
By absorbing enough body tissues of supernaturals with different properties, the garden would gain an increase in quality that would help it to advance into the next level.
The agreement did not say how many people had to sacrifice, but it did mention an estimated proportion—90% of the participants would die.
