For the Five Elements Academy, its greatest resource was still spirit stones. Nearly fifty to sixty percent of all the spirit stones in the Underground World came from its territory.
Even more astonishingly, nearly seventy to eighty percent of the high-quality spirit stones came from the Five Elements Academy.
This was the greatest reason the Five Elements Academy could stand among the Three Great Academies.
In terms of foundations, the Five Elements Academy was inferior to Taiyi Academy and Titan Academy. Its hard power was also below that of those two academies.
But the advantage brought by spirit stones alone was enough to let the Five Elements Academy stand as an equal alongside the other two, forming a three-way balance of power.
Now, the situation had changed, and the strengths of the various sides had waxed and waned. The balance of power had undoubtedly shifted in subtle ways.
Jiang Yue had spent three years among the Five Elements Academy, so of course he knew its ambitions and schemes.
Now that he had returned to the place, the teleportation array that he and his companions had destroyed earlier had already been repaired. It had since become the largest transportation hub in the Five Elements Academy's territory.
Even though the teleportation array had been repaired after that round of destruction, the Spirit Veins still couldn't operate at one hundred percent capacity as they had before.
At best, the array's transportation capacity and operating efficiency were now just over eighty percent of what they had been. They fell well short of ninety percent.
And although the array had been repaired, if it were damaged again, the consequences would be serious.
Even if they managed to repair it somehow, its transportation capacity and operating efficiency might suffer an even greater loss.
Having learned their
