Holy Rhino seemed to agree to Han Sen's offer. It roared and then entered the Cruel Bottle.
Han Sen was delighted about this, so he put a lid on it. For the rhino, this was similar to humans taking refuge in the Alliance, away from the sanctuaries where the motions and terms of a contract were always in play. For the duration it was in the bottle, the rhino was safe.
Saint Fan now couldn't kill the rhino for switching its allegiance, but if Han Sen wanted to enlist Holy Rhino as an ally in the future, he knew he'd have to take down Saint Fan once and for all.
Unfortunately for Han Sen, he could not yet kill Saint Fan. If anything, that frightening spirit was more powerful than ever. It was highly likely the rest of the super creatures inhabiting Saint Fan Shelter would be absorbed to become a part of him.
