Two days passed in the blink of an eye. After Karsha shocked Morr by telling him about his new sister, they had more conversation. According to Morr, after absorbing the Destiny blood, he has touched the barrier to becoming a World Boss and has also closed the gap to ascend to Tier 9.
This, of course, is a great development. If he becomes a World Boss, he will be able to crush all those at the Great Sage stage, even if he remains at Tier 8.
However, the process of reaching Tier 9 and becoming a World Boss won't be easy. He will have to endure a heavenly tribulation when ascending to Tier 9 and for each subsequent Tier. To become a World Boss, he will have to undergo a trial that he will only discover when the time comes.
In short, when he leaves for the island, he plans to go into seclusion for perhaps a year or two, depending on how long it takes to become a World Boss finally. He intends to become a World Boss first before attempting to ascend to Tier 9.
