It is also for this reason that Nanierga is hailed as another great miracle after the Three Holy Swords, with the title of "Wall of the Source," and its technical content is said to surpass even the super-large floating magic-guided battleships, of which there are only three in the Source.
If this great wall can be successfully completed, with the wall holding off the defending battle, that empire might not have been destroyed.
However, unfortunately, before Nanierga was completed, that empire had already fallen.
But with Nanierga, all the major forces that came to aid that empire were still able to successfully repel the Abyss invasion, preventing the Abyss army from advancing one step further.
Now, thousands of years have passed, and this great wall has assisted the Source in resisting the Abyss for thousands of years and still stands today, which shows how strong and tenacious this wall is.
