Mike estimated that these undeads would be able to maintain Elinda's body for several thousand years. He calculated that he would only need to capture a few more when he counterattacked the Otherworld, and that should be enough.
He was ready to get down to business. A few months ago, the Great Magus had sent Mike news that the Sea King had already left the Otherworld. His assessment of the Otherworld was that he had only met two divine-tier experts. If the imperial palace had not taken into consideration Mike's reputation, they would not even have needed to send out divine-tier experts.
After Mike learned of this news, he cursed at the Sea King. Two divine-tier experts? If he were to say that there were 200 divine-tier experts in the Otherworld, he would believe it. Although 99% of them were only comparable to a large-scale heaven-tier expert, and although they already possessed divine power, they were unable to mobilize the power of heaven and earth.
