Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

In the early morning of September 23, 2019, a natural disaster arrived. The Dao of Heaven and Earth has changed, the desire of all souls have completely filled up the Heavens.

The Dao of Heaven can no longer bear it. Evil thoughts, good thoughts, obsessions, and desires entangled endlessly, making the Heavens reach its limit, this shift caused an extreme change in the world, making fantasy come to reality.

All worlds fused together, and all things compete for freedom in this cruel new world. This is the beginning of a new era, one filled with destruction and rebirth. This era is called the Eternal Era.
