Badass, the rise of the emperors in the modern era

In the year 2084 several portals appeared on earth from which all kinds of monsters and terrifying existences descended, when everyone thought that it would be the extinction of humanity a voice sounded in the sky.

"Welcome to the endless era, all past eras converge in the current era, the powers in their bloodline that have been sealed for millennia will begin to awaken, all the ancient temples will appear and within them will be cultivation methods, magic skill books, divine weapon forging methods, apart from of his awakened powers of his bloodline each will have a system with the ability to level up, see you soon, I hope humanity can rise to the top once again".
