Although Fang Zheng found the developments of this world perplexing, it did not mean he was without means. By using Ratziel, Fang Zheng had almost effortlessly discerned the development direction of the Holy Grail War in this world, as well as what exactly the World Tree of a Thousand Realms was.
In Fang Zheng's memory, the turning point of the original Holy Grail War occurred during the Third Holy Grail War, when the Einzbern Family's Servant was the first to be defeated. Unwilling to bow out, the Einzbern Family forcibly summoned the eighth Heroic Spirit—Evils of the World. However, contrary to its fearsome title, this Evils of the World was utterly weak and was easily defeated.
After that, the Evils of the World that was recovered into the Holy Grail corrupted the Greater Holy Grail, leading to a series of troubles in the Fourth and Fifth Wars.
