With Lu Chen's current strength at the Peak Integration Stage, although he was still far from a true immortal, he was already capable of traveling to a designated minor world, provided he had the exact coordinates.
The coordinates of minor worlds were rather different from the latitude and longitude of the real world; they were formed from disordered strings of characters representing various elements such as time, location, and space, which then had to be combined and processed through complex formation calculations to be obtained.
Furthermore, not a single element could be wrong, otherwise it might lead to accidentally straying into the void and never being able to return.
