[The blurb isn't doing this story justice, so you might as well read it.]
In the future, in the new century of 2066, humanity has left Earth for other habitable planets. Many cultural traditions have been lost, and countless delicacies have vanished. They say portals to other worlds can lead to these long-lost traditions and foods. Many powerful clans and experts venture into the vortex of other worlds. It appeared a long time ago, but not everyone who enters it will meet there. The vortex leads to the Myriad Worlds. Members of a select few clans possess portals of their own, which they use to travel to the Myriad Worlds in search of delicacies and cultural traditions. Bringing these traditions back can change the future, where people have been reduced to living on nutrition supplements.
Murong Yuechen is the 666th gatekeeper of the Murong Clan. Like the other members of his clan, he has a portal, but he discovers that his can only lead to a post-apocalyptic wasteland. The portals of the other clansmen can reach the Myriad Worlds. Once inside, he binds himself to the Universal Eco-Recycling System. By recycling trash in the wasteland, he earns points that he can exchange for all kinds of resources and food. He can even get equipment and rare treasures!
Can he become a powerful expert through the world beyond his portal? Can he change life in that world and reach the pinnacle of success?
