What Prince Zhen Nan wants now is something that can completely conceal Lu Chen's realm, as only such a treasure or cultivation technique can better protect Lu Chen.
However, finding a treasure or cultivation technique that can completely hide one's realm is not an easy task. Despite having lived for so many years, he has never heard of any treasure or technique that could completely hide a person's realm.
Many treasures can hide one's aura, but if faced with highly advanced Spirit Martial Artists, one's realm might still be easily discerned by them.
At this moment, Prince Zhen Nan said to Zhao Yu: "Have the Hidden Guard discreetly inquire if there's a treasure that could perfectly conceal Chen'er's realm, such that even Earth Realm experts can't discern it."
Upon hearing this, Zhao Yu was momentarily stunned. Like Prince Zhen Nan, he too has lived many years and never heard of a treasure capable of completely concealing realm aura.
