After pondering for a while, Luo Hongye ultimately agreed to Li Qing's trade.
In terms of rarity, an Immortal Fruit Seed far surpassed a stalk of Nine-Leaf Profound Spirit Grass. To an alchemist of her extraordinary skill, it held an indescribable allure.
Immortal medicines were unique beneath the heavens; even in the immortal world, this held true. Once one existed, a second identical immortal medicine would never be born.
Unless the original immortal medicine had been utterly uprooted, only then might that particular immortal medicine reappear elsewhere after hundreds or thousands of generations.
And if the fruit seed borne by an unknown immortal tree remained after the original tree had been felled and its roots completely severed, there would be a chance to use that Immortal Fruit Seed to plant another immortal tree.
Of course, growing immortal trees and immortal medicines anywhere outside the immortal world was nearly impossible and required exceptionally harsh conditions.
"Fine, I accept this trade. When can you give me that Immortal Fruit Seed?" Luo Hongye asked.
Li Qing pondered for a moment, then said, "At most, in around a thousand years, I will present that Immortal Fruit Seed to you with both hands!"
A thousand years might be exceedingly long to mortals or Immortal Cultivators with low cultivation, but to Body Integration Realm experts like them, it was no more than the flick of a finger.
Luo Hongye nodded and said solemnly, "Fine. Since you were introduced by that fellow, I'll trust you this once."
"You may take the Nine-Leaf Profound Spirit Grass in advance, but a thousand years from now, I must see the Immortal Fruit Seed you spoke of!"
In response, Li Qing immediately swore a Heart Demon Oath upon his Great Dao, declaring that he would certainly present an Immortal Fruit Seed
