Obsidian Age

There are two strongest forces on the Epoch Continent, the Eastern Empire, which is famous for its numbers and superb iron-casting technology, and the Natural Federation, which has emerged with its mysterious biology and super individual combat effectiveness. Besides these two countries, there are many small countries living in the cracks between them. Su Yu was just an ordinary person in a small country at the junction of the two countries, but he was involved in the vortex of this war because he had the obsidian blood of the Natural Federation that had been missing for many years.
