Return of the Heavenly Monarch

Synopsis

He was away from home for 3 years... and away from his world for 3,000 years. 3 years ago, he fell into a rift, into a world of immortals, where time flew differently. He struggled 3,000 years there to come home, only to find his family... gone. Now a 3,000-year-old monster, will he slaughter his way to the reunion, or... will he have to start all over again?
