Prologue

At some remote corner of the universe

3 billion years ago 

A spatial tear appeared at this location , out of which a white robed man walked out.

He carried a dignified disposition with an aura of omniscence. Yet at this moment his current appearance betrayed his disposition. With a pale face , disheveled clothes and blood pouring out of numerous wounds on his body, the man looked like he was about to breathe his last any moment.

"I guess this is it for me. But even if it is the end I shall follow my lord's dying wish and make sure that this universe remains untouched."

Taking out a dome shape artifact from his robes he chanted some ancient spell that caused the dome to disintegrate. 

"With the "Heaven's Protection Dome" I can guarantee that this universe would remain untouched for the next 3 billion years."

"But I need to make sure that in the worst case scenario, the natives could fight back. I realize that my life is about to end, hence I need to establish the presence of mana in this universe and leave it all to fate "

As he spoke this the man started muttering in an ancient language following which his body started turning transparent.

"O children of future please not let your universe fall into the hands of those bastards".

With these words the man disappeared completely and all that was left was a crystal at his place.
