"But how should I get in?"
Li Zhirui's brows were furrowed tight. His method of concealing his mana was decent, but it was not so flawless as to be undetectable in front of Nascent Soul cultivators!
Suddenly, he remembered a type of Spirit Grass he had once obtained from the Xuanfa Pavilion—the Rongxi Cao!
After consuming it, one could completely meld their aura into the surroundings, plus with a fourth-order Invisibility Talisman, as long as Li Zhirui didn't make physical contact with a Demon Cultivator or circulate his mana, he wouldn't have to worry about being discovered.
'The Precious Pill has not yet been refined, but it seems that the Rongxi Cao will come in handy first.'
He silently retreated several miles, took out a stalk of fresh Spirit Grass from his space, consumed it, and then applied the expensive fourth-order Invisibility Talisman he had purchased.
