Earlier, he wanted to use this place as a base to create a great enterprise. Of course, by using it as a residence, if he went out for work, there would inevitably be traces. If those Taoists or monks discovered his whereabouts!
If they joined forces to deal with him, even though the Invincible Sect Patriarch had the confidence to withstand, it would still be very troublesome!
An individual's ability might be able to fend off many weaklings, but if several capable beings attacked together, it could be quite a challenge!
He also needed to use this Yin Soul Formation to cover his traces and fend off external troubles!
