Temporary Allies 

As soon as he got close enough to the top of the hill, Minos noticed the cultivation of the surrounding men, either those who were there to cause trouble, like him, or those who were part of Firestone Mines, the guards stationed around the portal.

The groups of people who seemed to have negative intentions toward the portal and Firestone Mine were basically Sovereigns with cultivation levels between 111 and 113. 

Meanwhile, the guards around the portal, who numbered over 50 people, had cultivation levels between 112 and 114.

There didn't seem to be any Supreme beings around, which was to be expected, since such beings would hardly stay outside their headquarters.

In a world where the strongest were Supremes, regardless of whether they were the strongest or weakest of the 12th stage, it was unlikely that such a strong specialist would be in a place like this, where there was nothing of great value for Supremes.
