Perhaps a "Great Demon" at the Profound Immortal realm could exhaust and kill hundreds of millions of Human Immortals.
However, legion warfare was different.
Forming Human legions, and fighting based on military formations and arrays.
Firstly, it could unify all of humanity's strength, concentrating it to kill Great Demons without internal friction or harming their own people.
Secondly, legions would have high-cultivation generals stationed at their center to harmonize the legion's power. The Great Demon would be unable to employ a kiting tactic and escape. Instead of the legion being exhausted, it would be the demon itself.
This was the way of gathering strength, defeating the strong with the weak, and attacking the many with the few.
In the war between the Wu and the Demons, the Demon race often attacked the Wu with hundreds of millions of demon soldiers. They also utilized military formations and arrays, using myriad demons as a formation to leverage their numerical advantage and fight against the higher-cultivation Wu.
Di Jun and Tai Yi, who were peak Quasi-Saint powerhouses, still required demon soldiers and generals as combat power. This showed that low-cultivation practitioners, when numerous, were not without purpose.
The Demon race already employed legion warfare.
The Human race naturally could not fall behind.
At present, the Human race's foundation was truly lacking. They did not have the conditions like the Demon Court, where myriad races united, and numerous innate divine beings jointly researched military formations and battle arrays.
In reality, the current Human race was still stuck in the mode of small team combat with three to five individuals, and had not researched any battle array or military formation techniques.
Since external sources were unavailable, Fang Ming could only choose techniques from the system mall.
"Although there are many battle arrays in the Primordial World, our Human race cultivates the Heaven-Shielding Method, and the battle arrays of the Primordial World are not very compatible. It is best not to choose this method if conditions permit."
"I recall that in the Heaven-Shielding World, many major powers also formed cultivator legions, practicing with 'arrays' to form profound formations, thereby exerting collective power beyond their own cultivation realm."
"Why not look at the battle arrays of the Heaven-Shielding World."
Fang Ming turned his gaze towards the battle arrays of the Heaven-Shielding World.
Even within the scope of the Heaven-Shielding World, there were many battle arrays in the system mall.
Many beings who achieved Great Emperor status and ruled the universe had formed vast forces and left behind battle arrays.
There were the ancient Heavenly Court battle arrays created by Emperor Zun, the Underworld battle arrays created by冥尊, the battle arrays of the Feathered Divine Dynasty...
From the Mythological Era to the Post-Ancient Era, they had everything. Fang Ming also saw the battle arrays of the Heavenly Court established by Emperor Ye, and the battle arrays of the Divine Court established by that old Golden Crow Great Emperor.
Whether it was a Heavenly Venerate, an ancient Emperor, or a Great Emperor, they were comparable to Saints in the Primordial World.
These battle arrays were basically equivalent to those created by Saints. Even the Golden Crow Great Emperor, known as the weakest Great Emperor, had a cultivation level comparable to a Primordial Saint, far surpassing the Quasi-Emperor level Golden Crows like Di Jun and Tai Yi.
It could be said that any battle array from a Great Emperor's force had a higher technical content than that of the innate divine beings in the Demon Court.
Fang Ming's gaze fell upon these battle arrays. He discovered that these Great Emperor battle arrays cost around three thousand to four thousand Origin Points each.
The battle arrays created by Great Emperors were different from the killing arrays created by Great Emperors.
The latter were terrifying in power and did not require relying on numbers to unleash their ultimate might. However, they were not something ordinary people could master; only peerless prodigies could.
Did one not see how proud the Black Emperor in the Heaven-Shielding World became after mastering a Great Emperor's killing array, constantly showing off beside Ye Hei for a long time?
These Great Emperor killing arrays were extremely expensive and could not be bought for three thousand Origin Points. They were also unrelated to the collective power of battle arrays.
The battle arrays created by Great Emperors for their subordinate forces were much cheaper.
Over the past hundred years, Fang Ming had extracted a large number of Origin Points due to the rapid development of the Xuanyang tribe. Even after spending some to improve the Human race's strength during this period, he still had a surplus of one hundred thousand Origin Points.
There was no difficulty in choosing now. He casually selected three sets of battle arrays created by Great Emperors and purchased them together, then taught them to the Human race.
Fang Ming summoned several elders from the tribe and directly said:
"The threat of demon invasion of the Human race has existed since ancient times and cannot be guarded against."
"I plan to build three legions and utilize battle arrays to fully leverage the Human race's numerical advantage."
"You have all reached the Immortal Four and Sage realm of the Heaven-Shielding Method, comparable to Golden Immortals in the Primordial World. You are sufficient to lead an army. You will each lead one of these three legions."
After spreading the Heaven-Shielding Method, Fang Ming's prestige in the Xuanyang tribe reached its zenith, and no one dared to defy him.
The elders did not care about the young chief and directly exercised their authority as tribal chiefs to give them direct orders.
They nodded repeatedly, absorbing Fang Ming's commands.
Seeing this, Fang Ming imparted the battle arrays purchased from the system mall to these three elders.
"Excellent! Our Human race finally has battle arrays!"
As one elder accepted the transmission of the battle array, tears seemed to well up in his eyes.
Battle arrays were not only key to defeating the strong with the weak but also crucial for legion warfare.
In the past, when demon soldiers and generals invaded the Human race, a single one or two was manageable. But if their numbers reached a hundred, they would immediately unleash the Demon Court's battle array techniques.
This had severely suppressed the Human race.
Despite having a numerical advantage, the Human race could not leverage the collective power of battle arrays to kill the demon armies.
Instead, they were crushed by the demon armies.
This was all due to the Human race's lack of foundation, unable to research their own battle arrays independently, leading to this disadvantage.
However, now, the young chief had actually passed down battle array techniques.
And was it not true that in this regard, the Human race was no longer at a disadvantage?
Instead, they could leverage their vast population to gain an advantage over the demon armies?
The elder thought about the current tribe, with over a hundred million Earth Immortals and more than five hundred thousand Heavenly Immortals.
If he, a powerhouse comparable to a Golden Immortal, were to be stationed at the center of the legion, harmonizing the power of the numerous Human soldiers with battle array techniques, how much power could be unleashed?
Many races among the Demon Court's myriad races did not even have a total population of one million. How could they resist such an army?
At this thought, the elder was overjoyed. He seemed to instantly see the brilliant future of this Human legion, radiating dazzling light.
Making many races among the Demon Court's myriad races tremble in fear!
"Young Chief, what level are these battle arrays? Can they compare to the Demon Court's battle arrays?"
"I heard that the Demon Court's battle arrays were created by many Great Luo Demon Gods, Quasi-Saint Demon Sages, and even the lord of all races, the Demon Emperor himself!"
Another elder was not as happy as the previous one.
He was slightly worried. The Human race now had battle arrays, but there were differences between battle arrays.
The Demon Court's battle arrays were created by numerous innate divine beings, making them peak Quasi-Saint level battle arrays.
