Chapter 638: Unfilial Descendants

Immortal Gu normally required immortal essence to activate. Under most circumstances, will could not activate Gu worms alone. Even Giant Sun's will was not exempt from this rule.

The reason the dragon of Giant Sun's will could activate Immortal Gu was because it was holding Giant Sun's immortal essence.

However, the wisdom Gu's attack cut apart the dragon of Giant Sun's will into two and actually revealed it was holding Giant Sun's immortal essence.

"As expected of wisdom Gu! Such an amazing result in just one move!!" Fang Yuan's gaze brightened and praised wisdom Gu inwardly.

He had also thought of cutting apart the connection between Giant Sun's immortal essence and Giant Sun's will, but he did not have enough strength to do so.

However, wisdom Gu accomplished it!
