An unknown event awakens everyone on Earth to become Card Masters. The world enters a data-driven mode, and countless secret realms descend upon Blue Star. Countless demons and monsters wreak havoc on the world, and behind these secret realms lie connections to countless other worlds. Card Masters rise to power, wielding extraordinary strength to explore the truth behind these secret realms. The protagonist, Lu Ziye, awakens a god-level talent and discovers the entrance to the "Howling Cave" secret realm in the basement of his own villa. Seizing this great opportunity, he commands spirit beasts, rises rapidly, and traverses various secret realms, seeking the unknown truth behind them.

The Barov family, a vast and mysterious clan of Arathor descent, possessed fiefdoms stretching from Brill in the north to Southshore in the west, from Tarren Mill in the south to Caer Darrow in the east. Reborn into such a family, Carlos was happy and content. In spring, he enjoyed the service of three thousand maids at Lakehold in Caer Darrow. Summers were spent escaping the heat in the apple orchards of Tarren Mill. Autumn brought vibrant red leaves to the maple forests of Brill. Winters were spent feasting on cod in Southshore. Whatever his needs, a simple ring of the Barov butler's bell would fulfill them. Such a life would make any trip to Azeroth worthwhile! If I hadn't played WoW, I almost would have believed it.
