Upon hearing Gu An's command, Sin began to carefully probe the mysterious causality clinging to the Great Dao.
At first, he only saw fog.
He continued to probe, pushing forward his vision, wanting to see the true face of the causality's origin.
After a while.
Sin suddenly frowned, his Immortal Emperor's Eye became hollow, his body trembled slightly, and he appeared stiff.
Gu An did not intervene immediately, allowing Sin to fully experience it, knowing that even painful experiences could broaden his horizons.
He continued to gaze ahead, seeming to admire the beautiful landscape, but in reality probing the Path of the Great Dao.
