As a human Lord, Michael had an increased chance of summoning his own kind. This chance was increasingly high for Summons with a low star rating.
Only with the expansion of his territory, and an upgraded Summoning Gate would the probability of summoning tamed Monsters, Demi-Humans, and other races increase.
Nonetheless, Michael was quite surprised that he had yet to summon a Gogi. By installing the Gogi Lord's Summoning Core, the probability of summoning a Gogi should have been higher than the chance of summoning Demi-Humans, tamed Monsters, and the Nature Spirit.
Now that the population of his territory expanded so quickly, Michael had to distribute tasks more carefully. He had to tend to the various needs of his new subjects, whether they were human, demi-human, or monsters.
