Soul Lake Memory Lock Seal was a soul-based cultivation spell that was a top-tier blue-grade art close to reaching the gold grade.

Despite being a blue grade art the degree of difficulty in mastering it was the same as a gold grade art. You needed at the bare minimum to be at the middle stages of the core formation realm for you to practice it and even then one couldn't do it without a strong soul.

Su Jinjing among Yang Qing's team had the strongest soul so she could practice the technique at the middle stages of the core formation realm but as strong as her soul was even with her cultivation base being at the later stages of the core formation realm she can only sustain the art for ten minutes at most and even then her soul would be left severely overdrafted.
