This is an extremely crazy idea. Even for Integration Cultivators, let alone Tribulation Crossing Realm cultivators, very few can accomplish this.

Because wanting to cleanse the Demon Occupied Zone in a short time comes with two major challenges that need to be overcome.

First: Siege warfare is by no means an easy task.

Defending a city is easier than attacking one; the Demon Race defending a city, taking advantage of the terrain, will surely not be an easy bone to gnaw.

Not to mention one person, even a fully equipped team of cultivators would find it as difficult as reaching for the sky to capture a demon city in a short time.

Additionally, if we cannot break the city quickly, the demonic cultivators from other cities in the Demon Occupied Zone will come to reinforce, making it difficult to even retreat, let alone break the city.

But Lu Qingshan is different.

Because he is a lone Sword Cultivator.

First, attacking a city alone will cause the demonic cultivators to launch a proactive attack upon discovering Lu Qingshan, rather than passively defending the city — there is no city of demonic cultivators in the world where, with many Seventh Grade and Eighth Grade cultivators, they would choose to besiege themselves in the city when facing an Integration Cultivator.

This causes the Demon Race to actively give up their geographical advantage.

Secondly, Lu Qingshan is a Sword Cultivator, and his attacking power and explosive power are unparalleled among Sword Cultivators, and he also possesses skills for group attacks.

Therefore, his speed in killing demons is also unmatched.

No one can compare to him, not even Dharma Cultivators who excel in group attacks.

This allows him to break the city in the shortest possible time.

Second: There isn't enough time.

The Demon Occupied Zone is vast, traveling from one city to another requires a considerable amount of time, not to mention cleansing all the demon cities in the area.

Moreover, siege is inherently a highly consuming and time-consuming task.

Ordinarily, after capturing a city, cultivators would need some time to recuperate and restore their state.

Siege + travel + preparation, when combined and no possibility of dividing forces to advance simultaneously, it seems that at least half a year would be required to reclaim Mang State.

But for Lu Qingshan, these are not issues at all.

First, as a Sword Cultivator, his speed using Escape Techniques is the fastest among all human cultivation styles, not to mention he is also an outstanding Sword Cultivator.

Secondly, Lu Qingshan cultivated to the Integration Realm with every stage of his Cultivation Technique being Taoist Level.

For Taoist Level Cultivation Techniques, among their basic attributes is a 100% increase in Mana recovery speed.

Additionally, the Great Xia Scripture (Integration Chapter) innate skill [Silver Candle's Clear Rhyme] again increases the Mana recovery speed by another 100% on this basis.

With these stacking properties, Lu Qingshan's Mana recovery speed reaches an unimaginable level, fully supporting him for continuous battles — simply put, it's like always having a blue buff.

Finally, and most importantly, Lu Qingshan's city attack speed is extremely fast and the consumption is far less than imagined.

Because with his current strength, for most Seventh Grade Demon Cultivators, Lu Qingshan only needs a simple Flying Sword strike to kill them instantly.

These achievements are due to numerous enhancements, including the might of the Taoist Artifact, innate attributes, and the special effects of his Secret Sword, which others simply cannot replicate.

Moreover, the consumption of Flying Swords for a Sword Cultivator is practically negligible, more akin to a basic attack.

This is one of the charming aspects unique to the Sword Cultivator profession, a scene hard for cultivators of other flows to imagine — once perfected, it's a single strike per "youngling."

Therefore, the two major difficulties that restrict other Human Cultivators don't exist in the eyes of Lu Qingshan.

In fact, it's not that there are no other Sword Cultivators who have thought of this.

However, having them take on enormous risks to penetrate deep into the Demon Occupied Zone to massacre cities — no one would do such a thing.

Because to accomplish this, not even Third Tribulation Realm Sword Cultivators are deemed sufficient.

After all, the weaknesses like frail physical bodies, insufficient defensive means, and inadequate group attack methods are very real for Sword Cultivators.

This makes it absolutely impossible for ordinary Sword Cultivators to face enemies several hundred or even several thousand times their size.

But Lu Qingshan possesses the Sword Domain, Sword World, Dustless Fighting Chamber, Heavenly Heart Abbot, Secret Sword: Winter Snow Welcoming, Secret Sword: Autumn Frost Coagulation, which either conceal or outright eliminate these weaknesses.

If not for possessing these abilities, Lu Qingshan would also ponder deeply before taking such actions.

Because it's too compelling and too dangerous.

Yet, with all conditions met, not taking such actions would make Lu Qingshan feel unworthy of being a Sword Cultivator.

......

Though in the perilous Demon Occupied Zone, Lu Qingshan feels like a fish in the sea, a bird in the sky.

In a Demon Occupied Zone lacking Ninth Grade Demon Cultivators, there's no one to restrain him.

He is like a vicious wolf entering a fold of sheep, utterly lawless and unchecked.

After effortlessly resolving the most troublesome Mangcheng, he only takes a short rest for an hour before starting from Mangcheng as his center, radiating out in a circular manner toward other cities in Mang State.

In just one day, Lu Qingshan annihilates the twenty-seven cities around Mangcheng in the Liuyun Province.

All demonic cultivators within the cities are equally slaughtered to the last.

Blood flows through the province.

Then, Lu Qingshan transforms into a Sword Light once again, heading toward the adjacent Gao Yun Province from Liuyun Province.

Amid numerous sonic booms, he is extremely conspicuous.

.......

In the tail currents of the Spirit Sea Tide.

Boom! Boom! Boom!

The rampaging Spiritual Energy and elusive spatial rifts obstruct the passage of the Divine Sense.

But if viewed from a God's-eye perspective to take in the whole picture, it would be found that the vast Spirit Sea Tide area looks like a chessboard divided by crisscross lines.

In those densely packed chess grids, there are battles occurring involving few as two or three "pieces" to as many as seven or eight "pieces."

In one particular "chess grid."

The ground erupts with uneven, varying-sized pits, with corpses strewn across, belonging to both the Demon Race and Human Race Cultivators.

Blood seeps into the soil, staining it black.

Above in the sky is a twisted and splendid stream of Spiritual Energy akin to the aurora at night.

Suspended around the Spiritual Energy stream are a few scattered Human Race Cultivators.

Their Taoist robes no longer shine bright, bloodstained upon them.

Along their faces are spread scars.

They have just endured a grueling battle, achieving a hard-fought victory.

Under normal circumstances, after going through such a battle, these Human Cultivators should find a safe place to heal and restore their state.

But at this moment, the Human Cultivators aren't doing so.

Because in their minds flashed the words Gu Qiu entrusted to them before marching into smaller units:

For every moment we delay the Demon Race, our chances of victory increase by a fraction.

The reason for this increased chance, the Central Spirit Cultivators do not know clearly.

But they trust Gu Qiu.

At the time when everything was tumbling, the Sword Sect's willingness to wage half its strength for a Western expedition had long won all the Central Spirit Cultivators' respect and recognition.

Thus, these Human Cultivators set off once more, scattering under the cover of the Spiritual Energy flow.

They have to keep fighting.

If they run out of strength, so be it?

They already have the answer in their hearts:

Then burn life.

After the Battle of Dragon City Pass, all true powerhouses in Central Spirit have fallen, leaving only "worthless fish and rotten shrimps."

Although the forces of reinforcements slightly bolstered Central Spirit Humans' strength, they are still far fewer in number compared to the Demon Race.

Central Spirit no longer possesses the stronghold of Dragon City, and the number and combat power of cultivators cannot compare with that of the Demon Race.

Judging by raw power, the disadvantage is glaringly obvious.

Yet the Human Race has the determination to protect their homeland, risking everything.

This is the Human Race's greatest weapon.

It is also the main reason that, should they be able to overcome the odds and drive the Demon Race from Central Spirit.
