The experiment went even better than Chen Lin had expected.
After the soul blemish underwent its qualitative transformation, he could improve it not only through cultivation, but also by refining soul-related heaven and earth treasures, just as he would normally strengthen his soul origin essence.
The only drawback was that it was rather slow.
But that was to be expected.

Rainbow City was populated almost entirely by High-Rank Cultivators, making the
