Yoon Byung-mo: Goguryeo Mountain Fortresses in the Liaodong Region 1 (Large Print Book)

The castle is evidence that it was the greatest power in East Asia at the time. The only country in East Asia has built such a powerful defense system. The high-end acid castle, which remains in the turbulent regions, including the yogi, is a paradox of how important it is to the region. Also, when the affected areas collapse, the virtually all - defense capability to climb is lost. That's why the gooeys are on defense using the rugged mountain terrain of the troubled region. The wisdom of the old men who can use the ruggedness of such a turbulent region tells us of the mountain castle that remains firmly fixed until now.
