The legendary breakthrough sites of Tianyuan City had already been prepared quite extensively.
These breakthrough sites required at least Superior-grade miracle buildings dedicated to breakthroughs as the cornerstone, supplemented by a large amount of materials and mysterious rituals.
However, without a Great Secret Realm that can gather the Power of Heaven and Earth and form its own cycle, there would be at most two breakthrough sites that could be established within Tianyuan City.
These miracle buildings were either transformed from the Ice Heart Lotus Platform by Isloa—after all, that building wasn't originally intended for breakthroughs—or upgraded to Rare Level Breakthrough Dojos by Mu Yuan using building upgrading stones;
The Exploratory Teams had even cleansed High-order Sources of Filth, resulting in the discovery of High-order architectural drawings for breakthrough buildings.
