Fang Yuan was helpless.
He could not force Lang Ya land spirit to do anything.
Right now, he was stuck here, even if he wanted to continue deducing the self cleansing formation, without the crucial Immortal Gu, it would not work.
"And most importantly, I need to borrow Lang Ya Sect's strength to refine Gu."
Fang Yuan obtained Purple Mountain True Monarch's inheritance, he lacked many Immortal Gu, he had a bunch of plans for what Immortal Gu to refine next.
If Lang Ya land spirit thought about it for a long time and still rejected him, what would he do?
Fang Yuan had considered this problem.
He always did things by considering the worst possible outcome first.
"If Lang Ya land spirit refuses to lend formation plate Immortal Gu, I will need to use other people's immortal apertures."
Fang Yuan had a lot of dao marks, it was hard to get into the immortal apertures of the other Shadow Sect Gu Immortals.
