The first and fourth functions of the Tianquan Creation Furnace can easily be determined for appropriate users, but the second and third functions, that's a different story.
If he doesn't handle it well, he might just end up creating a battlefield of carnage.
Both of these functions were evaluated by Han Li at their limits, meaning he would only use them to help cultivators enhance their aptitude to Immortal Grade, evolving into Immortal Bodies.
Given that the second and third effects can only be used twelve times a year, Han Li had no choice but to make the most of them.
Both ascending to first-grade aptitude and birthing special constitutions could be achieved through the Life-Prolonging Furnace, and Han Li could lend his aid, evolving a King Body into an Emperor Body.
Because the annual usage is so limited, even Han Li can't distribute the opportunities evenly. Therefore, he decided to pair the two functions together for use.
