Although Han Fei was a Sea Quelling God, it was a little unrealistic to kill 16 God Slaying-level powerhouses with a stomp of his foot. If he fought them in a sealed barrier, although as a Sea Quelling God, he could definitely kill 16 God Slaying-level powerhouses, it would take some time. At least, it would take hundreds of seconds. After all, the God Slaying-level powerhouses definitely had treasures on them.
Therefore, it was a better choice to defeat them one by one. Even if someone discovered that something was wrong with the Bloodline Divine Tree halfway, Han Fei didn't care, because this war had already begun the moment he took action.
After only a hundred seconds, the remaining 16 God Slaying Level powerhouses were all harvested in the same way.
