The Heaven-Mending Gathering is very short, only lasting three days, because among those attending the gathering, not everyone has acquired longevity artifacts, so life is extremely valuable.
The wilderness is abundant, yet items that extend life are rare.
It wasn't always so rare; over the years, anything that could extend lifespan has been extensively consumed, and not to mention the average ranger, even the elders of the Nuwa Clan may not possess them.
Therefore, even the Heavenly Emperor must personally cultivate a herb garden and plant divine medicines.
Although it's called a herb garden, it is actually composed of hundreds of thousand-foot-tall mountains, full of extraordinary treasures and strange grasses.
Something like 'Xun Grass' can enter the Emperor's Herb Garden purely because women like it, there's a market demand for it, and Qingyao Mountain almost monopolizes the business of Xun Grass.
