When he had laid down the Underhand Sect's foundation in that nameless valley, Wu Qi suddenly reflected on something the people of Luo Clan had told him in the Mi Province. They claimed that there was a copy of the Pangu's Map in every Prefecture Overseer's Mansion, a treasure that allowed one to clearly see the changes of energy in every single underground energy vein, through which, one could notice the activity of Immortal cultivators!
In order to build a strong and solid foundation for the Underhand Sect, he needed a vast amount of Immortal stones, energy stones, as well as various spirit herbs to cultivate all the disciples. It meant he would have to excavate energy stone veins and harvest various spirit herbs. He even planned to find a blessed land where he could connect all the underground energy veins together, and produce an Immortal Mansion for the sect.
