After Su Yang and the others returned to Qinghe Academy, they immediately asked someone to find some crystal gemstones.
Using the method recorded in the Heavenly Destiny Treasure Book, Su Yang set up a very intricate array inside each crystal gemstone.
To activate the power of this array, Su Yang found the four Beigong War God individuals and had them infuse some of their divine artifact power into the crystal gemstones.
With this, the aura of the array became extremely powerful.
Coupled with the array originating from the Heavenly Destiny Treasure Book, which was already remarkable, the addition of the divine artifact power made the array even more extraordinary.
After processing the four crystal gemstones, Su Yang brought them to the dean and others for appraisal.
The dean and others, who were considered well-experienced, were utterly shocked upon seeing the crystal gemstones.
"How could there be such power in this world?" the dean exclaimed in astonishment.
