The Immortal Profound Power left on the Heavenly Termination Ancient Emperor back then flew towards Ye Xuan at this moment, merging with the Immortal Profound Power Ye Xuan had previously taken back.
This was the backup move Ye Xuan left behind casually years ago, serving as a lesson for the Heavenly Termination Ancient Emperor.
In fact, when Ye Xuan returned to the Empty Ancient City and faced the Heavenly Termination Ancient Emperor, even without using the City Soldiers of the Empty Ancient City, he could easily defeat him.
However, at that time, Ye Xuan was probing a question, concerning the Ancient Characters obtained back then.
Those Ancient Characters in the Dao Chu Ancient Land contain terrifying power.
This time returning, besides gathering information from the Suspended Fate Immortal, Ye Xuan also intended to observe the reaction of the Ancient Characters.
Additionally, it was time to reclaim the Immortal Profound Power.
