Ordinarily, Wood Spirit's departure had been proposed by Angel, so to a certain extent, he had an obligation to protect Wood Spirit.
From that perspective, it was acceptable for the reward section of the contract to be left blank.
However, the contract drafted by Wise Sovereign was different.
He had added contractual terms and penalties for violating them, and the penalties were severe, involving the Sea of Spirit and Soul Land.
Of the three major transcendent faculties possessed by wizards, only the thought space had not been mentioned. But that did not mean the thought space would remain unaffected. Injury to any one of those three faculties would, to a greater or lesser extent, affect the others.

The contract's power explicitly stated that it was a Level Two backlash granted by the Will of the World. This level of backlash was already extremely high, equivalent to half of Angel's mental-force tentacles snapping at once. It would inflict a tremendous blow upon his Sea of Spirit.
