The Emperor's sword was meant to make whoever was struck by it experience the ravages of time all at once, effectively accelerating the aging process to the point where they'd show symptoms of dementia.
After being hit by that sword, Song Shuhang's consciousness began to drift.
At that moment, his spiritual awareness split into two.
One part synchronized with the Sage's Eye, which received data from the Heavenly Emperor, refining and relaying it back to Song Shuhang.
The other part, influenced by the power of time, floated higher and higher, like he was intoxicated.
Song Shuhang felt like his mind was clear, but he couldn't control his drifting spiritual awareness.
After floating for a few seconds, the power of time, influenced by the "Age Sword," served as a bridge that connected Song Shuhang's consciousness with that of another "Song Shuhang" from a different frequency.
——It was the "Old Tyrant Song" attached to Daozi's back!
