"Airborne"

Li Xingyao did not rush to act, but instead maintained the suppression of his aura while expanding the Soul Banner Domain to its maximum.

A perceptual map with a radius of 50,000 kilometers unfolded in his mind, and the entire capital city appeared like a detailed topographical map.

The scale of the capital city did not exceed his expectations: the entire city was buried thousands of meters underground, with the rock strata above it being more than two thousand meters thick, and the highest point of the dome being five thousand meters above the surface.

The city's total area is dozens of times larger than the Abyss Empire city he had previously conquered. If it were on the surface, it would probably be equivalent to the area of ​​a medium-sized country on Earth.

The sensory feedback from the Soul Banner domain revealed a clear structural hierarchy within the Imperial Capital.

The outermost layer consists of densely packed residential and commercial areas, while the interior is cluttered and crowded, with countless tiny specks of light moving about like ants in the streets and alleys.

Further inside are the military fortresses and the mansions of noble lords, where the energy fluctuations are significantly stronger, and the aura of Saint-level beings is densely distributed.

The core area is a massive palace complex built of dark purple crystals, surrounded by three energy barriers, each radiating the power of Saint-level laws.

Deep within the palace complex, an energy core, resembling a purple sun, was slowly pulsating.

The moment Li Xingyao's senses touched that core, he felt an aura of majesty as heavy as a mountain—

That was the unique law fluctuation of a peak Saint-level expert, a power exclusively belonging to the Emperor of the Abyss Empire.

"The limit of the peak of the Saint rank..." Li Xingyao silently assessed in his mind.

With his current strength, plus the support of the undead legion, dealing with enemies of this rank should not be a problem.

However, if the opponent has other tricks up their sleeve and can push their strength to the point of being infinitely close to the threshold of a Star God, then we need to be even more cautious.

However, Li Xingyao quickly shifted his attention away from the emperor.

This empire's capital is a repository of the wealth and resources accumulated by the Abyss Empire over tens of thousands of years.

The secret vaults within the palace complexes, the treasures in the noble mansions, the strategic materials in the military fortresses, and the ultimate treasure buried deep beneath the entire capital—

Once he has all of these, he can obtain all the resources he previously estimated he would need within a few days.

"Let's begin." With a thought, Li Xingyao gave the command to all the undead in the Void World.

The next moment, the air around him suddenly twisted violently, and grayish-white summoning lights lit up one after another.

Like jagged cracks tearing through space, the undead legions of the Ruins of Return poured out in droves.

The first to emerge from the light was Flamel. The massive skeleton of the Saint-level Undead Nether Dragon slowly stepped out from the teleportation aura. The moment its wings spread, the entire abandoned warehouse trembled violently under its dragon domain.

Immediately afterwards, countless undead of the same rank emerged one after another, forming neat ranks around Flamel, their icy undead auras blending into a vast, dark blue sea of ​​stars in the darkness.

Next came the mage legion led by the lich Alex. A large group of liches appeared in the eerie light of the teleportation array, and the star crystals at the top of their staffs were surging with deathly waves that could freeze one's blood.

More undead poured out of the teleportation beam.

The Death Knight rode his Nightmare steed, its hooves casting eerie blue flames that spread across the ruins.

The Shadow Eater blends into the surrounding shadows, like a flowing mass of darkness.

The heavy footsteps of the raging giant ape echoed through the passage.

The vengeful spirit floated silently in mid-air, like a grayish-white mist.

In just a few dozen breaths, more than 15,000 Saint-level level 9 undead legions had assembled in this abandoned warehouse outside the capital.

They stood silently in formation, their chilling aura of death surging like a rising black tide, instantly covering an area of ​​tens of kilometers around them.

Almost at the same instant the undead legion completed its summoning, Li Xingyao's Soul Banner Domain detected intense reactions throughout the capital.

Those Saint-level experts scattered throughout the military fortresses and noble mansions sensed the immense aura of death emanating from the outer city almost simultaneously.

One after another, figures flew out from their respective locations and rushed towards the abandoned warehouse.

"Prepare for the enemy," Li Xingyao calmly gave the order.

Flamel let out a deafening dragon roar, and his massive body took off first, charging towards the incoming Saint-level experts.

The Death Knight and the Dark Ranger followed closely behind, like two gray arcs of light, flanking and surrounding them from both sides.

Alex led the lich mage order in chanting, and a deathly, gray-black mist rapidly spread across the capital city.

The first group of Saint-level experts from the Abyss Empire who arrived numbered about thirty, all of whom were at the advanced to peak Saint level.

The moment they saw the undead army, their faces showed disbelief and horror.

Li Xingyao's undead legion is already well-known among the high-ranking officials of several major empires, but how did these "things" that should be in the Axis Empires end up in the capital?

But as the core fighting force of the Abyss Empire, they had no time to figure out the reasons, nor did they choose to back down.

Instead, they quickly formed a battle formation, attempting to use the power of the Law of Unity to control these undead legions here, awaiting support from others.

However, they were facing a hundred times more Saint-level level nine undead, and they also had the help of divine artifacts!

Flamel's Nether Dragon Breath swept across, controlling the three Saint-level 9 Shadow Mages, along with their Law Domains, within a single area.

The Death Knight's runic greatsword unleashed a storm of sword energy, sending the charging Saint-level warrior flying backward.

The Dark Ranger's arrows rained down like a storm, each one carrying a death mark that locked onto the shadow assassins attempting to ambush them.

The death and decay of the lich mage corps covered a large area. The power of law on the Saint-level experts shrouded in gray-black mist was dissipating at a visible speed, and their movements became more sluggish.

Everything went exactly as Li Xingyao had predicted. Once the vanguard stopped the offensive and the artifact joined the battle, the fight ended in just a few minutes.

Of the more than thirty top Saint-level experts from the Abyss Empire, not one escaped.

Their souls were unsurprisingly devoured by the Myriad Soul Banner, transforming into pure soul power that flowed into the ocean of soul power.

And this is just the beginning.

Li Xingyao hovered above the abandoned warehouse, his Soul Banner Domain spreading out, allowing him to perceive all the movements in the entire capital city.

He could see more Saint-level experts rushing from all over the capital, and he could also see people frantically packing up their belongings and trying to move them from noble mansions and military fortresses.
