"Ningxi, why aren't you eating?" Liu Ruolan asked with concern.
"Great-grandmother, the grade of these ingredients is too high; eating even a bite makes me fear my qi and blood will become overly vigorous," Wang Ningxi made a contemplative face, "Moreover, I can't figure out this last tough problem, so I've lost my appetite."
"Come, let your great-grandmother have a look." Liu Ruolan stepped forward and glanced it over, and then a stroke of inspiration hit her, "This is simple, just do it like this, and like that..."
Wang Ningxi's eyes lit up: "Indeed, just like this and like that... Thank you, great-grandmother; now my path to the Heavenly Human Realm in my cultivation is completely clear."
The Enlightened One and others unfamiliar with Liu Ruolan stared at this scene in amazement, wondering how this could be. Who exactly is Liu Ruolan, who could pinpoint the critical issues at a glance?
