The Taixu Wonderful Spirit Pill—that was an item of the immortals.
Although the ingredients required could also be gathered in the Spirit World, in all these years, no one had ever heard of anyone being able to refine such a thing.
Legend had it that even in the True Immortal Realm, only masters deeply skilled in alchemy possessed such ability.
For the other party to make such a demand was clearly an intentional attempt to make things difficult for Lin Xuan.
Yet they had not violated their promise.
After all, what the two sides had agreed upon back then was the refining of a kind of pill that would be of great use to a Tribulation Transcendence Stage cultivator in breaking through a bottleneck.
And the Taixu Wonderful Spirit Pill's effect lay precisely there.
Moreover, its effect in breaking through bottlenecks was far better than that of several other kinds of pills.
Its value was so great that it could almost truly compare with a Xiantian Spirit Treasure.
So although what the other party was doing was a trick, in plain truth, they had not violated the promise, and Lin Xuan had nothing to say.
"Husband."
Ouyang Qinxin's face was filled with worry.
Although with her strength, she was still unable to come into contact with such high-end treasures, from Fairy Heavenly Sound's expression, she could also guess that her husband had most likely fallen into the other party's trap.
Lin Xuan's expression was indeed incomparably gloomy, but there was no intent to admit defeat. "Who says Lin will violate the promise? I haven't even tried yet, so how would I know for certain that I can't do it? Has the Quiet Room for refining pills been prepared? And the Waste Pills the fairy promised to provide me?"
"Oh?"
