The Vigor Pill was indeed refined by alchemists from various precious spirit herbs, designed to bolster one's vital breath. Despite being only the size of a green bean, its hefty price tag alone reflected its rarity—making it an indispensable resource for those aspiring to enter the Vigor Realm.
Wang Wu had spent years cultivating with his decent innate talent and strenuous practice, employing every means to gather the resources needed to progress to the latter stages of the Essence Nourishment Realm, yet to advance from the late stage to the peak of the Essence Nourishment Realm, he would still need to use a total of fifteen bottles of Essence Nourishing Liquid.
Only in this way could he bring his vital essence to an apex, allowing for the consumption of the Vigor Pill. When circulating his cultivation technique, it would then better enhance his vital breath.
