The building in Zhou Yan's hand transformed into a sinister, grand hall, and after being enveloped by a multicolored light, it evolved into an entirely new structure.
This new building was even more eerie and bizarre, exuding an aura of terrifying darkness, like a realm from hell.
Fortunately, Zhou Yan possessed Yin and Yang energies within him that were far more potent and purer than this oppressive darkness.
Upon hearing about this building, Zhou Yan was quite astonished.
He even wondered if the evolution of this barracks was a consequence of him already possessing the "Underworld."
"In this case, wouldn't all the 'Soldiers' of this territory be able to be assigned to the 'Underworld'? After all, the entire 'Underworld' currently only has Nie Xiaoqian."
Zhou Yan examined the "Underworld Ghost Soldier" barracks and found it to be remarkably peculiar, much like the barracks of the "Ten Thousand Demon Kingdom." It had no limit on the number of soldiers it could house, which was a significant advantage.
Zhou Yan immediately began upgrading the "Underworld Ghost Soldier" barracks.
After reaching level 20, the "Underworld Ghost Soldier" barracks required soul stones for further upgrades. Zhou Yan found this quite coincidental, as he had purchased a considerable amount of soul stones, including many eight-star ones, during his trip to the Soul Continent.
He directly upgraded the "Underworld Ghost Soldier" barracks to level 90 before examining its detailed attributes.

[Description: In the Underworld, infinite ghost soldiers. Every 3000 soul coins consumed can randomly summon one Underworld Ghost Soldier.]
"Nie Xiaoqian is too lonely as the only ghost. Now, I can summon more ghost soldiers."
Zhou Yan immediately entered the barracks. Although the atmosphere was chilling and unsettling, having experienced the "Underworld," this barracks was a minor matter.
Inside was a dim world, filled with an oppressive yin energy, devoid of light, and saturated with a profound nether aura.
Zhou Yan walked onto the summoning platform of the "Underworld Ghost Soldier" and began summoning soldiers.
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost Soldier."
A soul-like light emerged from the summoning altar and descended.
A man with a pale complexion stood there and addressed Zhou Yan, "Wu Liang greets the Lord."
He looked similar to Nie Xiaoqian, with one being a male ghost and the other a female ghost.
Zhou Yan continued to summon.
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Female Ghost."
Looking at a pale-faced woman standing below, Zhou Yan was surprised.
So, this barracks could also summon female ghosts, meaning he could even form a female ghost legion.
The thought made Zhou Yan envision Nie Xiaoqian personally commanding a group of female ghosts on the battlefield. The scene would be breathtaking.
He continued summoning!
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost Soldier."
...
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost General Hero [Ox-Head]!"
"Ox-Head pays his respects to the Lord."
Looking at the ghost general with an ox head and human body standing below, Zhou Yan fell into contemplation.
He wondered if he could also summon figures like the Ten Yama Kings, the Ten Ghost Marshals, the Twelve Ghost Generals, countless Ghost Kings, and Ksitigarbha Bodhisattva.
If he could, he might truly be able to assemble the entire staff of the "Underworld," and then... then what?
Use them as soldiers to seize territory, women, bah, people!
Attacking other lords could indeed result in the plundering of populations, but whether these individuals could be utilized depended on how the lord treated them.
Ghost soldiers were a special type of troop because they required no food and could survive in any place with yin energy.
This was the fundamental difference between the dead and the living.
Zhou Yan continued summoning.
The number of ghost soldiers grew from one thousand to two thousand.
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost General Hero [Horse-Face]!"
...
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost General Hero [Black Impermanence]!"
...
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost General Hero [White Impermanence]!"
When the number of ghost soldiers summoned reached ten thousand, a notable hero appeared.
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost General Hero [Night Roamer]!"
"Night Roamer!" The name sounded familiar, and he was indeed a figure, a ghost marshal-level being.
According to the "Classic of Mountains and Seas: Southern Classic of the Wilderness": "The Nan Zhong Yi tribes may have them. Those who encounter them at night are not surprised by the locals, who call him the Night Roamer."
The Night Roamer was responsible for guarding the night, while his counterpart, the Day Roamer, protected the world, one during the day and the other at night.
The Night Roamer was one of the Ten Ghost Marshals. Although he looked strange and even fierce and ugly, he was an rrr quality hero. Naturally, these ghost soldiers would be placed under his command.
Moreover, the Night Roamer had a night-time bonus. In battles fought at night, his combat power would double, and the strength of the ghost soldiers under his command would also increase significantly, making him a valuable asset.
Zhou Yan continued summoning. When the number of summoned soldiers reached fifteen thousand, he indeed summoned another ghost marshal, the Day Roamer.
The Day Roamer and the Night Roamer, along with Black and White Impermanence, and Ox-Head and Horse-Face, made a total of six generals.
However, Black and White Impermanence, along with Ox-Head and Horse-Face, were only r-quality ghost generals, suitable to be minor officers.
When the number of ghost soldiers summoned reached thirty thousand, a truly noteworthy hero finally appeared.
[Underworld Ghost Soldier] notification: "Soul Coins - 3000, Summoned one [Underworld Ghost Soldier] Ghost General Hero [King Qinguang]!"
It was said that King Qinguang was in charge of longevity and early death, as well as the registers of birth and death in the mortal world; he uniformly managed the punishments in the netherworld and the fortunes of the next life.
Furthermore, his skills were excellent. Under the cover of night, he could control the fortune and misfortune of enemies, extend the lifespan of the living, and even directly take lives.
Of course, this was only effective against weaker opponents. If an opponent was powerful, King Qinguang could not accomplish such feats.
Regarding extending the lifespan of the living, it was also related to the individual's strength; the stronger they were, the less lifespan could be extended.
Even for ordinary people, the extended duration was limited and did not guarantee true immortality.
