It might have been because Zhou Tian offended that Divine King too severely at the time. Although it was necessary to pay a certain price to possibly invite the deities from the outside world, to guarantee one hundred percent success in capturing Zhou Tian, that Divine King invested much more than Zhou Tian had anticipated.
Based on that Divine King's investment, it's estimated that even an ordinary Divine King would be tempted at that time!
The bounty for killing Zhou Tian included one hundred deityhoods and billions of divine coins. Moreover, the Divine King also promised that if any deity who killed Zhou Tian would defect to him, not only could they choose a location as their fief within his sphere of influence, but he would also do his utmost to help them break through to the Divine King realm.
When such a bounty was offered, it naturally immediately attracted a large number of deities.
