Moreover, although the Yin Yang Sect was far weaker than the enemy coalition, it had a steady stream of reinforcements arriving.
The Alliance Leader Wan had constructed teleportation arrays between all four major families, similar to the one between the Yin Yang Sect and the Kui Lian Sect, which could transport large quantities of supplies such as war vessels and killing weapons.
This was incredibly advantageous for them as the defending side.
Reinforcements from the Thunder Emperor Hall, Kui Lian Sect, and the Fang family were continuously advancing towards the Yin Yang Sect, bolstering their strength.
Excluding the Tribulation Transcendent combatants, the Thunder Emperor Alliance was not significantly inferior to their opponents in terms of mid and low-tier combat power.
Their opponents consisted of three peak powers along with over two hundred thousand demon generals and resentful demons, giving them a higher combat strength than the Thunder Emperor Alliance. On the other hand, the Thunder Emperor Alliance had gathered the armies of the four major families, the might of the Four Heavenly Pavilions, and countless assassins from the Heavenly Tribulators.
This was a relatively favorable situation for the defenders.
As for the affiliated rogue cultivators and guest elders, both sides had many, but these individuals were weak and could almost be disregarded, serving as mere cannon fodder on either side.
The Thunder Emperor Alliance's greatest concern was the disadvantage in the high-tier battles.
This was something that no amount of guest elders could compensate for.
All the Tribulation Transcendent old monsters in the entire Thunder Wind Realm had been concentrated here.
They had no reinforcements left.
When Qiong Ku saw the arrival of the Yin Yang Sect's reinforcements, he knew that the opposing side intended to fight a decisive battle here.
Therefore, Qiong Ku harbored no unrealistic hopes of annihilating the entire Thunder Emperor Alliance within a day or two.
The combined armies numbered over ten million, with at least Nascent Soul stage cultivators or higher, representing the pinnacle of power in the entire Thunder Wind Realm, all converging here.
This was a war that would determine the fate of a universe, a decisive battle!
It was not strange for this war to last for years or even decades.
After all, the war between the positive and negative planes had already been ongoing for fifty thousand years, with neither side able to gain a decisive advantage.
All three teleportation arrays of the Yin Yang Sect were constantly lit, responsible for teleporting the armies of the other three families.
Qiong Ku knew that to destroy the Yin Yang Sect more quickly, he first had to destroy the enemy's teleportation arrays.
If they could be destroyed, the speed at which the other three families supported the Yin Yang Sect would immediately slow down or even halt. Large war vessels would have to travel slowly, and he could dispatch his armies to intercept these reinforcements midway, weakening and dividing the enemy.
He could not spatially seal off the Yin Yang Sect, otherwise, other reinforcements would be deterred from coming. "Pincer attack to intercept reinforcements" was the best tactic.
The Yin Yang Sect, naturally aware of the importance of their teleportation arrays, had dispatched their most elite forces to guard them.
The battlefield below was progressing with difficulty. The Yin Yang Sect had established effective firepower nets between its various peaks, and for the demon race to advance, they had to meticulously destroy every formation on each hilltop, seize or destroy the spirit cannons, otherwise, their rear would be attacked when they moved to attack other areas.
Positional warfare was the same everywhere; it was never about rushing for speed. This was a process of dislodging stakes.
The coalition forces concentrated their strength to attack from the periphery inwards. Initially, their progress was relatively fast, but the further they advanced, the more dispersed their forces became, the stronger the enemy's defensive firepower grew, and the more difficult the fighting became.
The suicide squads dispatched by the demon race to destroy the teleportation arrays were all intercepted and failed to destroy them.
Three days passed in the blink of an eye. The alliance's Tribulation Transcendent cultivators were all holed up within the Yin Yang Life-Death Plate and beneath the inherited Kui Lian of the Kui Lian Sect. Although they sustained injuries, they were not too severe.
The demon race's offensive grew increasingly difficult. Qiong Ku, witnessing this during the battle, was quite dissatisfied with the pace.
Qiong Ku decided that it would be more reliable to send a Demon Marshal to destroy the teleportation arrays.
His gaze swept across the entire battlefield, searching for a suitable candidate.
Over thirty Demon Marshals and seven Tribulation Transcendent cultivators, everyone except Liu Nai Weng, had arrived.
Qiong Ku's gaze fell upon Qian Niao, who was "diligently" fighting, making him grit his teeth in frustration.
This was a decisive battle, and victory was all but assured, yet this fellow was still slacking off!
He would let anyone go, but not Qian Niao, otherwise, he would surely engage in a battle of three hundred rounds with some Nascent Soul cultivator from the opposing side.
"Demon Marshal Qiu Wu, Liu Zhong Wu, you two go and destroy those teleportation arrays!"
"As you command!"
Immediately, a Demon Marshal and Liu Zhong Wu disengaged from the battle, flew high into the sky, and headed towards the direction of the Yin Yang Sect's rear mountain.
On a flat mountaintop in the Yin Yang Sect's rear, stood three towering teleportation arrays, which Wan Lei had painstakingly set up decades ago at the request of the Yin Yang Sect.
Because reinforcements were continuously being teleported out from here, the protective formations could not be fully deployed.
Here, three Great Perfection stage elders of the Yin Yang Sect and seven Great Perfection elders from other supporting forces, along with a group of Nascent Soul and Soul Transformation cultivators, were guarding this area.
In the Yin Yang Sect, there had always been a legend about the true cultivation level of Elder Da Zhuang, who had guarded the Venerable Scripture Pavilion for thousands of years.
After all, three thousand years ago, when the current sect leader was still an unregistered disciple, this elder was already guarding this place.
This usually grinning, somewhat dirty, chubby old man liked to sit at the entrance of the Venerable Scripture Pavilion, set up a small table, place a platter of pig's head meat or braised chicken legs, and a pot of wine, sitting in a grand chair, enjoying himself immensely.
Of course, his primary focus was eating; the wine was merely an accompaniment.
Although this old man had a somewhat eccentric personality, he was mostly amiable and kind. When disciples went to the Venerable Scripture Pavilion to search for cultivation techniques, he would enthusiastically help them find what they needed and recommend the most suitable ones.
If any disciple had any questions about their cultivation, they could find him, and he would answer everything they asked without reservation.
The disciples of the Yin Yang Sect were quite fond of this old man, as most of the Yin Yang Sect elders were too detached from worldly affairs, making it rare to encounter an enthusiastic one.
However, this old man had a peculiar habit: whenever he encountered disciples with good potential, he would always try to keep them, enthusiastically promoting his "Da Zhuang Invincible Version" of Yin Yang Dao Yun.
Unfortunately, it was said that only Alliance Leader Wan had successfully cultivated it to date.
Initially, no one believed in his so-called Yin Yang Dao Yun, but after Alliance Leader Wan succeeded and then achieved an astonishing series of victories, breaking through cultivation realms at an astonishing speed, people gradually began to believe in it and rushed to learn the Invincible Version.
It was precisely because of Wan Lei that these Yin Yang Sect disciples, who initially considered themselves quite formidable and therefore rather indifferent, realized the gap between themselves and true prodigies, and began to cultivate desperately, becoming increasingly competitive.
