Some time ago, someone arrived at the Desolate Ancient Relic—now the Dao Source Sacred Site—and found the true place where the Dao Source World Tree took root. They watered it with a strange liquid. That strange liquid revived the Dao Source World Tree, but it was no good thing in itself. It was something that forcibly prolonged life, meant to make the Dao Source World Tree shine briefly before death and borrow its power to refine a treasure.
The Fate Gate that the Witch Clan had broken open with Xunyoudu had, in a sense, interrupted that person's actions and nearly caused all his efforts to go down the drain. To make up for the losses, the Witch Clan, along with the many people in the Dao Source Sacred Site, became sacrifices—part of the materials. The Dao Source World Tree itself was both the Cauldron for refining the treasure and one of its primary ingredients...
The person behind all this was extremely powerful, so the Dao Source World Tree's will did not intend for you to stop him. Nor did it believe you possessed such strength. It merely hoped that, before it completely withered and was refined into a treasure, you could find an environment where the Dao Source World Tree's seed could survive. That way, it might still have a chance to live.
Such an environment was not easy to find. If it had been simple, it would have found someone at random to do it long ago. Though few came here after the turmoil, the Dao Sect and the Witch Clan had still sent people here from time to time.
Zeli had originally been quite curious about what made you so special that the Dao Source World Tree trusted you so deeply and believed only you could accomplish this.
