Having the genes of a demon king, I never intended to be a kept man.

[System: Task has been issued!]

[Content: The exercise is about to begin. Enemy troops are approaching. Please defend the Great Wall!]

[Mission Requirements: Defend the Great Wall for 30 minutes.]

"General, what does this mission mean?"

A human warrior looked at the mission prompts on the system panel and asked this question.

Thirty minutes... it's over before it even started, right?

In this era, it is common for a war to last for months or even years.

What can you train in 30 minutes?

General Chen Wu snorted coldly: "It seems that Lord Ye Ge has little trust in the combat capabilities of our human imperial army, and is also very unaware of the defensive capabilities of the Great Wall."

"Does Lord Yege think that their Ye family's army can break through our imperial army's defenses within thirty minutes?"

The deputy said with a serious expression, "If that's really what they think, then it's incredibly insulting!"

Even if the Ye family's army is very capable in battle, isn't thirty minutes a complete joke?

Let alone the Ye Family Army, even the top ten armies among all races could not breach the Great Wall in thirty minutes!

The Great Wall, a super defensive fortification built during the reign of the First Emperor, possesses extremely powerful defensive capabilities. It is the culmination of all the wisdom of the Qin Dynasty over thousands of years, the ultimate product of the combination of technology and magic. Generations of mechanical masters and rune masters have left countless efforts on the Great Wall!

The Great Wall is also humanity's greatest reliance in the face of its many powerful dark race neighbors!

The walls, hundreds of meters high, are entirely forged from soul steel, making them indestructible. Every few hundred meters along the fortress are special high-level magical runes, subtly connected to the magical metal buried beneath the walls. In the event of an invasion by external enemies, these rune devices will be activated, forming a massive barrier in the sky to block all intruders, thus creating the first line of defense.

This kind of barrier can even withstand an attack from a Soul Emperor realm expert!

As long as the energy supply can keep up, the barrier can be continuously charged. In the past, when energy relied entirely on magic stones, there might have been concerns about insufficient energy. But now that there is liquid energy, there is no need to worry at all. Even if a Soul Emperor-level expert leads an army of all races, it would be impossible for them to break through the barrier within thirty minutes!

Even if the energy barrier is broken, the human warriors stationed on the Great Wall can hide inside the Great Wall fortress, close all entrances, and every window on the Great Wall will be covered with three-inch-thick soul steel armor to ensure the absolute safety of the warriors hiding inside the fortress.

Then the Great Wall will activate its automatic enemy-annihilation mode. All the mechanical gears will start up, and every fifty meters behind the Great Wall, there will be a towering lightning tower. These lightning towers will release all the lightning energy stored in advance during thunderstorms. The lightning power will connect with each other to form a huge high-voltage lightning net, which will electrocute all enemies who try to cross the Great Wall.

Meanwhile, the human warriors, huddled inside the Great Wall fortress, could use firearms and cannons to attack the enemies outside, protected by the fortress's impenetrable walls.

If it weren't for the existence of the Great Wall, the human race, which doesn't even have a single Saint Realm expert, would probably have long been at the mercy of the dark races.

After Empress Longying ascended to the throne, the Great Wall, the first line of defense, underwent several reinforcements and upgrades over the past few years.

The Great Wall is now even more fortified than it was eight years ago!

“I originally thought that Lord Yege, as a high-ranking official of the empire, must be very knowledgeable about the empire’s important defense hubs.” General Chen Wu shook his head: “It seems I was wrong. It turns out that Lord Yege can also be arrogant.”

But it's normal.

Although Lord Nightsong is a graduate of the War Academy, due to his noble status, he did not join the Night's Watch or the Imperial Army. He probably only heard that the Wall was very strong, but did not know exactly how strong it was.

Today is the perfect opportunity for Lord Night Song to broaden his horizons!

"General!" At that moment, the deputy beside him, holding binoculars, suddenly said, "Enemy troops have appeared ahead!"

"Oh? You've arrived?" General Chen Wu narrowed his eyes.

He stood on the edge of the city wall's battlements, gazing into the distance.

The ground shook violently.

On the distant horizon, a dark, surging mass appeared in view...

"what is that?"

General Chen Wu, holding his binoculars, saw the surging black fog and showed a surprised expression.

In the distance, the dark, surging tide stirred up clouds of sand, making it impossible to discern its exact size.

At first glance, judging by their sheer presence, they seemed to number at least a million!

Does the Ye family have that many soldiers?

Chen Wu found it unbelievable.

He remembered that the Ye family always focused on quality, not quantity, when training soldiers.

Although the Ye family now holds the title of Duke of the Southern Territory, their directly subordinate private army still numbers only around 100,000 to 200,000.

"Could it be that Lord Night Song has also brought in the armies of other families in the Southern Territory to participate in the exercise this time?"

"General! That...that doesn't seem to be the Ye family's army?"

"What......"

General Chen Wu picked up the binoculars again.

On the distant horizon, beneath the billowing dust, one could finally make out what that dark, surging tide was.

It was neither the Night Clan army nor any human army.

They were a group of demonic creatures!

"It's a demonic tide!"

General Chen Wu let out a surprised sound.

Moreover, the demon warriors he saw through his telescope were not any of the demons he knew!

"Demonic Tide???"

"The army we're exercising with is a demon army??"

"How can it be......"

"Why would Lord Night Song bring in the demon army to conduct exercises with us?"

"General..."

The dungeon raiders and the warriors on the city wall all panicked.
