Time flowed on!
Three days passed in the blink of an eye.
Over those three days, the Gu Clan, Yan Clan, Lei Clan, Yao Clan, and Underworld Alliance all mobilized their full strength.
Working at full capacity, the major powers gathered staggering quantities of resources, which streamed continuously from the various clans toward the Underworld Alliance's territory.
All of this was because the major powers intended to join forces to refine a Ninth Grade Golden Pill.
Refining a Ninth Grade Golden Pill required not only vast quantities of resources, but also an exceptionally quiet and secure environment.
On the present-day Dou Qi Continent, nowhere was safer than the Underworld Alliance's territory.
Originally, Gu Yuan and the others had reservations about refining the Ninth Grade Golden Pill at the Underworld Alliance. After all, by any measure, doing so within his Gu Clan seemed safer.
But once Gu Yuan and the others learned just how terrifying the Underworld Alliance's grand formation was, they were shocked speechless.
The Underworld Alliance's defensive formation could actually withstand attacks from a Dou Di. When Gu Yuan and the others heard this news, their shock was followed by doubt.
After all, how could such a terrifying formation possibly exist on the Dou Qi Continent?
It could actually withstand attacks from a Dou Di.
Thus, when the major powers arrived at the Underworld Alliance, Chen Xuan concealed nothing. He directly invited Gu Yuan to unleash his strongest attack against the Underworld Alliance's formation.
Upon hearing Chen Xuan's words, Gu Yuan remained somewhat cautious.
After all, as someone at the peak of the late nine-star Dou Sheng stage, he naturally knew how terrifying his strength would be if he unleashed it in full.
Therefore, when he first attacked the formation, Gu Yuan used only seventy percent of his strength.
