Zhengyang Immortal Envoy, that is, what Li Zhengyang mentioned about the conditions of a First Grade Immortal Envoy, was a kind reminder, akin to a mutual exchange of favors, and by addressing him by his real name, he indicated that he was treating Han Yi as an equal.
Upon hearing this, Han Yi contemplated thoughtfully. Currently, he indeed possessed the combat power of a Half-Immortal. Even without using the Sword Controlling Immortal Skill and relying solely on the fragments of the Heavenly Demon Halberd, with his mastery at the Extreme Realm, he had a chance to slay a Half-Immortal.
Moreover, after a year, when he gathered two bottles of Undying Divine Liquid, he was confident in breaking through to the Undying Realm.
By then, the mere power of the Undying Realm would allow him to annihilate a Half-Immortal. With the three systems in play, even a Peak Half-Immortal could be slain, and he could even attempt a challenge against an Immortal.
