Dual Realm Exchange System

Damian Baines is an overworked young man who has been thoroughly exploited by the world around him simply for having basic humanity. When he pushes himself past his limits to pay bills that would have crushed anyone else, he transmigrates into the magical world of Valoria, full of dragons, wizards, and monsters! But that is not all! Damian awakens a special power in the form of the Dual Realm Exchange System, which allows him to traverse between two worlds with different power systems and capitalize on it! On one side is the bright magical world of Valoria, and on the other, the dog-eat-dog cultivation world of Shengyuan. Items from one side that typically cannot work on the other are adapted and enhanced, leading to a monopoly of power and resources that shakes the foundations of both realms forever! — Description from novelcodex.org
