Jiang Yi's decision was wise. If he had followed the Little Eagle King back to the Purgatory Mystic Realm, he would have been walking right into a trap. Heavenly King Wu and Heavenly King You were both headed there.
The two Heavenly Kings made one round around the Divine Yang Mystic Realm, but when they failed to find Jiang Yi, they decided to go to the Purgatory Mystic Realm instead!
To both of them, it did not matter whether Jiang Yi had killed You Tianni; he would end up in the Purgatory Mystic Realm for sure because that was a good hiding place. Jiang Yi could remain in there for twenty days given his skill level. It must have meant that he learned some secret technique or realized some mystical ability, which would enable him to remain there for thirty or even a hundred days.
