The Great Wall, which is the border between the north and the lonely land, is different, and its establishment dates back to before the first year of the Landau calendar.

Aliens are naturally physically stronger than humans, and most of them become irritable and extreme in the extremely harsh environment. In order to survive, alien races frequently go south to plunder human resources and livestock, and even kidnap young and beautiful girls, and have since become a tool for them to vent their primitive desires.

King Byron, the former king who ruled the north at the time, proposed to maintain peace in the north by signing a treaty with foreign races. However, his idea is still too naïve, aliens are different from human beings, and their temperament is much more brutal - if human nature is good, then the alien mind is born with a crippled heart.

The leaders of the alien race ostensibly agreed to the terms of the Entente, but secretly continued to harass the northern borders of the empire. This was so unbearable that Byron finally chose the latter in peace and war.

The former king of the north personally led 100,000 elite soldiers to the north, deep into the lonely land to engage in fierce battles with foreign races.

History is full of suffocating tragedies, the young king died at the claws of a foreign people, and the heart-wrenching wound in his chest made the hearts of all the soldiers ache.

Three months later, the legion finally returned to northern land, but with Byron's decomposing corpse.

Less than 5,000 of the 100,000 elites remained, and most of them were seriously wounded. The army slowly returned to the city, it was an early winter morning, and there was a dead silence in the city, and no one asked what had happened in those days.

"Young king, why is your crown bleak?

On the lonely land, the banner of the empire flutters, the war-torn desert, and the majestic figure watches over the eternal sorrow.

When the midnight moon comes, the light of God will always shine in the direction you are going. ”

This ballad has been sung by the people of the north for thousands of years, but Byron's death was not as heroic as the ballad suggests—it was just a cut in the chest by an ordinary soldier of the alien race in battle.

The whole country was in deep grief, and the new king, in order to defend himself against the foreign invasion, united the rest of the human empire and began to build the most majestic structure in the history of Landau, the Great Wall, on the edge of the lonely land!

Since then, the Great Wall has been guarded by the combined forces of the Human Empire all year round, and the soldiers guarding the northern border are not idle people, but carefully selected from the armies of various countries.

Even though there are constant wars between human empires on the continent, there is more unanimous human opinion on the issue of alien invasion than ever before.

Until Caesar's reign 80 years ago, when the entire Starfall Continent was ruled by Caesar, the Great Wall was still guarded by nearly 50,000 soldiers day and night. Even if the human world is in flames, it has nothing to do with the defenders of the Great Wall. They don't care who the king of the north is, they only care when the aliens will come again, even though it's been a full five hundred years since the last invasion.

However, since Julius Caesar unified the entire human world, the defenders of the Great Wall have been reorganized, and now they are only stationed here by some old and weak soldiers.

——

When Brandon and Merlin crossed the Wall, only a handful of soldiers patrolled back and forth on the wall, and many more slept around the fire in the tower.

"Why are the guards of the Great Wall so lax now?" Merlin asked Brandon in a low voice.

Brandon also found it strange that the guards of the Great Wall had been guarded by the most elite troops since ancient times, but these obscene-looking creatures looked even inferior to ordinary soldiers.

For unknown reasons, the various human empires recalled all the soldiers originally stationed at the Great Wall in just one month. This may have something to do with the increasingly turbulent times, the Empire's helpless actions to protect itself.

Just imagine, in the end, there were less than 5,000 soldiers left, and if they were to be scattered on a defensive line of nearly 10,000 meters, it would naturally seem very small. What's more, most of the soldiers who stayed behind were tired of the fighting, or they were simply evading responsibility.

However, to Merlin's disbelief, the soldiers on the city walls had clearly spotted them, and they should have acted on it. But they neither stepped forward to inquire about the identities of the two, nor did they step forward to stop them. Instead, he watched the two of them cross the Great Wall coldly, and there seemed to be a gloating expression on their faces.

Merlin shuddered at the thought of this, and the soldier's eyes were full of resentment, as if he wished they had gone to the lonely land to die.

"Brandon, let's go. Merlin's gaze looked at the distant starry sky and couldn't help but sigh. Brandon was now wearing a short white robe, armor forged from the finest Mithril, and the spear in his hand glowed with a cold cold light. He nodded, then turned to look south, the outline of the walls casting lonely shadows in the moonlight.

Brandon's eyes showed a look of sadness, and he examined the crumbling walls, the intricate cracks like sharp blades piercing his chest. He remembered the good time the four of them had spent together in the adventurous land, and tears welled up in his eyes.

"Merlin, we're never going back......" Brandon let out a long sigh with a look of dismay.

"Bran, it is said that there is a legendary dragon in the lonely land, and maybe we can meet it!" Merlin didn't seem to hear Brandon, his eyes shining with excitement.

Brandon couldn't help but laugh dumbly when he heard this, and said, "You guy, it's really-"

"Hey, hey. Merlin straightened the hood above his head, his trademark smile on his face, sly, yet sincere.

The magician knew in his heart what Brandon meant when he said that, but he was the opposite of what Brandon thought. Merlin never dwells on what happened in the past, he has always looked at people and things with an optimistic and positive attitude, and is full of hope for the future.

In just five years, he had become the same as Brandon is now—perhaps it would have been more appropriate to call him a Seraph. But that's all for later.

However, Merlin obviously did not anticipate the changes that would follow, and his light gray pupils could read through all the esoteric magic books, but could not see through the cold human heart hidden under the gorgeous exterior.

Merlin took a deep breath, his eyes only on the vast expanse of land in front of him, despite a lifeless mist hanging over the surface.

"Bran?" the magician patted the swordsman on the shoulder, and Brandon turned his head with a look of confusion on his heroic face.

"We've got to hurry! Because every moment of delay distills Diana's condition gets worse. Merlin spoke firmly, and the cold wind hissed like a serpent as it swept by, echoing for a long time in the dry air.
