In this vast space, there is not only the current world that only mortals can recognize.
Instead, there are twelve time and space coexisting with a strange and evil demon world. This story begins with one of them, the golden time and space...
He is the chief combat regiment leader of the Time and Space Iron Guards. In order to fight for justice and evil, he organizes groups to travel through time and space.
The friends he made in golden time and space-Wang Dadong, Ding Xiaoyu, and King Arthur.
These few players with high combat power index on the KO list were injured and lost all their skills while fighting against the evil forces.
Xiu's current duty is to go to another time and space, find Wang Dadong's secret, and teach each other the skills with him. This can prevent all twelve time and space from falling under the forces of darkness, and save the decline of the current golden time and space.
With this arduous task in mind, Xiu came to the same quadrant, the iron space-time where he belonged.
By chance, he discovered the secret of Wang Dadong, Xia Tian who had a very high supernatural power index.
And he is also very likely to become the only strong person in Iron Time and Space, the ultimate Iron Man. Once this identity is established, Xia Tian will have the ability to save the Twelve Time and Space.
…………
However, when the war of all iron time and space ends, it is also the beginning of another kind.
The kind-hearted and simple Xia Tian wanted to help Dadong, the leader of the Golden Space-time, recover his powers. However, he accidentally fell into the Copper Space-time and met his old enemy-Zack.
A smoke belonging to the copper space-time is about to disperse again...
The ultimate fighter - Xia Tian. Are you the savior?
