The weakening of the Spirit Tree had made the heartstrings of Jun Wu Xie tighten. Although they had just met once, the Spirit Tree had still intervened into this matter and rescued everything at the most crucial moment of the Soul Sacrificing Event. Jun Wu Xie believed that even if the entire Soul World was sacrificed, with the strength the Spirit Tree got, it was not difficult for it to keep itself safe. After all, it was much easier to use the power which it had used to destroy the Soul Sacrificing Event to protect itself.
Even if the Soul World was demolished, as long as the Spirit Tree still existed, it could still rebuild another Soul World and create more souls.
However, instead of doing such a thing, it had chosen to sacrifice itself to protect the entire Soul World and those spirit envoys who were always loyal and faithful to it.
