Lind went into seclusion for a time. No one bothered him as his work was mostly done but he kept an ear out if he was called.
His heart demons were barely formed but their roots were deeper than expected. He was an Immortal so forming a heart demon was not so easy but removing them was just as difficult.
He examined his heart and mind to find that he was rushing himself. He wanted to resolve the issues of the Fiends not only to save his family but to advance. He could cultivate in the current world but how much faster would he be without the tainted Qi?
Instead of having to cleanse it, he could storm ahead to refine the elements and Laws into his crystal. He was still only at the lower end of the Crystal Tier and his progress was abysmal.
