Sitting cross-legged on the floor of the eighteenth layer of the Ancient God Tower, Yan Ling'er slowly closed her eyes.
In her hands, she formed an unknown spell.
As she was shaping the spell, the entire eighteenth layer of the Ancient God Tower suddenly burst into endless light, which set the entirety of the tower humming loudly.
From outside the Ancient God Tower, it was clear to see that the entire eighteenth layer was shining with endless purple light.
The wondrous events did not stop there; following the illumination of the eighteenth layer in endless purple light, the seventeenth layer too started to shine brightly with the same endless purple light.
Then came the sixteenth layer, the fifteenth layer, the fourteenth layer...
Ye Chen, who was challenging the Ancient God Tower in the opposite direction, watched as the tower lit up from top to bottom under the control of Yan Ling'er's spell.
