Saint Demon Continent, Yu Long Pass.
Night had fallen.
The howling north wind occasionally let out mournful wails.
It was clear that the land had entered the early stages of Severe Winter Cold Snow.
Among all six Great Passes on humanity's side,
Yu Long Pass was the most unique and the most crucial.
From a defensive standpoint, its fortifications and defensive capabilities were undoubtedly the strongest.
That was because the entire Great Pass had been built against the mountain, with its main structures located within it.
Moreover, Yu Long Pass had the harshest conditions.
It was situated within the Extremely Northern Bitter Cold Land.
Affected by the environment, the four seasons could not be clearly distinguished there.
Although the soldiers stationed at Yu Long Pass were likewise affected by the harsh weather,
the impact of the bitter winter climate on them was far less than its impact on their enemies.
With the vast area of this mountain, coupled with the freezing winds and accumulated snow,
it directly formed a Natural Moat that was nearly impossible to breach.
At the very front of Yu Long Pass stood a two-hundred-meter-high slope.
The terrain was exceptionally steep and covered in ice and snow all year round.
Trying to attack from below was extraordinarily difficult.
Even if the Demon God Emperor's legion arrived in person, it would be difficult to overcome the countless obstacles of high mountains and towering ridges.
Breaking through this Great Pass from any other direction was simply impossible in the short term.
As a result, in this bitterly cold land,
during the initial phase of the Holy War, the Demon Race suffered severe non-combat casualties.
Now, they could only continuously select, redeploy, and eliminate troops.
Those remaining outside Yu Long Pass were almost entirely Demon Race units with Cold Resistance.
