Back when he was at Linyang Market, Lu Xuan had obtained a spirit plant used to make tea—the Second Grade Qingmiao Spirit Tea. The mature leaves of this tea were known for their ability to calm the mind and improve clarity. The Cleansing Spell that Lu Xuan had been using up to now was derived from the white light clusters generated by the mature spirit tea.
However, compared to the Fifth Grade Pure Luli Tea, it was like comparing clouds to mud.
Pure Luli Tea required a highly specific environment made from spirit aura and spirit soil to thrive. Ordinary spirit soil could even have an adverse effect on its growth.
"Then I'll just plant this spirit seed in that incomplete secret realm. The spiritual energy there is pure and concentrated, untouched by mundane influences, turbid air, or polluted auras. Gathering some pure spiritual energy shouldn't be an issue."
