The Card Apprentice - Chapter 567 - The Transit Windows

Kai of the Sorcerer’s Tower is one of the last mages left, barely surviving in a world ruled by creatures of the dark — where the era of mages ended, and most of the lands got contaminated with dead mana. To save his world and fulfil his master’s last wish, he put himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past. In an era with abundant mana — an era yet to enter the Golden Era of Magic. Things go wrong, of course, as they always do, and he finds himself thousands of years before the world fell to mana contamination — in the body of a young lord, Arzan. All is not well, though, as the young lord was murdered by someone right at the cusp of a beast wave threatening the territory, while larger threats loom on the horizon. There was a lot to do for Kai to regain his former strength in this time of primitive technology, but then again, he might just be able to change that.

Countless dungeons appeared across the rifts… and demons.Rocky Stephens, the first son of a Great Clan, the reincarnator, carrying memories from another world.… yet also a useless piece of trash. No one even remembered his name. His parents died. Betrayed by the branch clan, his beast was killed. He lived in a phase he had never dreamed of—a nightmare.When a second chance came, he returned to the World of Beasts… and awakened a system that could see through all Beasts’ training paths!With the system, his beast could level up like the wind… it could learn and upgrade its skills on its own, and even more.
