In front of the portal Isaac was having the time of his life, at first, he doubted about using the last spirit herb inherited by his ancestors to stablish a relationship with an elder from the sand mountain sect.
But now he was sure it was the best decision of his life, a couple of days ago he was contacted by his subordinates, they informed him that inside of the "secret realm", a power which surpassed the star tribulation realm was found.
Not only that but they even told him they made a deal with some ignorant natives to give in their resources in exchange for help to get rid of some worthless enemies.
Isaac was in ninth cloud, the elders of the sand mountain sect didn't receive any intel, so he offered them information and a share of the resources his subordinates got, in exchange of arranging a marriage with one of the granddaughters of the supreme elder.
