Within the Nether Demon School's underground prison, the captured Yuqing Daoism disciples were imprisoned here.
The prison was filled with powerful restrictions, and it was almost impossible to break through them with magic power alone.
Furthermore, they were all severely injured and suppressed by the restrictions, making it difficult for them to even breathe.
Their hair was disheveled, their bodies were weak, and their eyes were filled with despair and emptiness.
Elder Xu and Elder Chu, in particular, were slumped on the ground like mud.
There was not a trace of light in their eyes.
Their cultivation bases had been destroyed by Mo Lin, and all of their meridians had been shattered. They were already crippled.
Although they were still alive, their hearts were already dead, and their hearts were filled with pain and despair.
Rumble …
A loud noise shook the earth and the mountains. The dungeon also shook for a while.
Several young disciples raised their heads slightly, and a trace of surprise appeared in their eyes.
Following that, another explosion shook the earth. The disciples seemed to have thought of something, and they looked at each other with joy in their eyes.
"Could it be that the Patriarch has come to save us?" one of the disciples asked.
They were still very young, and their hearts were filled with a strong desire to live.
Even if it was only a faint trace of hope, it was enough to give them a new lease of life.
"From the sounds of it, it should be. This is great, the Patriarch hasn't abandoned us!"
"Elder Chu, Elder Xu, the Patriarch has come to save us, we're saved!" the disciples shouted excitedly.
However, Elder Chu's eyes were still lifeless, and he didn't say a word.
There was no greater sorrow than a dead heart. Even if they made it out alive, what could they do? They were already crippled.
"Kill them, we must kill all of these bastards!" Elder Xu shouted through gritted teeth.
His eyes were bloodshot, and they were filled with hatred.
The cultivation base that he had cultivated for hundreds of years had been destroyed just like that, and this was even more painful than death.
Thus, he hated the people of the Nether Demon School to the bone, and the only thing he could do was to kill them.
…
In the air above the Nether Demon School, the spherical purple light screen was constantly being compressed.
Bolts of purple lightning condensed and struck down at Li Yu, but they were easily dispersed by his sword.
Outside the light screen, a group of Nether Demon School's elders and several hundred disciples were arranged in a strange formation while simultaneously forming hand seals.
Strange runes appeared in front of them, connecting with each other.
Purple light condensed around them and slowly merged with the light screen of the array.
According to Li Qingyun, they were using the Human Formation to reinforce the Protective Mountain Formation, achieving the unity of the Human Formation.
It was as if he had become one with the sword.
This was completely different from relying purely on magic power to support the formation.
In order to become one with the formation, one needed to infuse one's essence, energy, and spirit into the formation, becoming a part of it.
Moreover, everyone communicated with each other through a special formation, allowing everyone to form a single entity.
This allowed everyone to concentrate their strength and unleash their greatest power.
This was like ten people pushing a box. If each person pushed, they might be able to push the box forward.
However, if the ten people's strength could be completely concentrated and unified, they could push the box further and faster.
If wheels were added to the bottom of the box and the principle of leverage was used to amplify everyone's strength, then ten people might be able to easily push ten boxes.
This was the effect of the Human Formation. Through the formation, everyone's will, strength, and spirit were unified.
Then, through the mysteries of the formation, everyone's strength would be concentrated and amplified.
It would produce a power greater than one plus one.
Of course, doing this would also make everyone a part of the formation.
When the formation was attacked, it was equivalent to them suffering a certain amount of damage.
If the formation was directly destroyed, they would also suffer a backlash from the power and be severely injured or even killed.
Therefore, when he heard Li Qingyun's words, Li Yu thought of a way to destroy the Nether Demon School with a single sword strike.
Thus, he began to conceal his strength and control his strength, only putting pressure on the formation.
Or, he switched from offense to defense, blocking the formation's attack but not completely destroying it.
"This brat can't hold on for much longer. Let's gather everyone's strength and kill him with the formation!" a Nether Demon School elder shouted loudly.
"Yes!" hundreds of disciples answered in unison.
At the same time, more Nether Demon School disciples flew over. They also formed hand seals and merged into the formation.
The purple light of the formation became more and more dazzling, and the energy became more and more tyrannical.
Rumble …
The formation was like a brilliant heavenly might, and thunder rumbled.
The purple energy gathered in one place, and a lightning bolt that looked like a flood dragon condensed.
Then, it struck down with a loud boom, heading straight for Li Yu.
Li Yu frowned and met the attack with his sword.
Boom!
Amidst the huge explosion, Li Yu hurriedly retreated with Li Qingyun.
Both of them had grave expressions.
Seeing this, everyone from the Nether Demon School was overjoyed.
It seemed that by fusing with the formation, they could unleash a terrifying power that could kill him.
"All Nether Demon School disciples, listen to my order. Come quickly and reinforce the formation with us to kill the enemy. Don't be negligent!"
The grand elder of the Nether Demon School used his magic power to reinforce his voice. It was like thunder, resounding through the entire Nether Demon School.
After a while, more figures flew over from all directions.
Some of them were patrolling the periphery, while others were in seclusion in various caves.
The previous commotion had attracted their attention.
However, they didn't know what was going on, so they didn't dare to leave their posts without orders.
Some of them just watched. After all, they couldn't imagine how powerful the enemy they were facing was.
They thought that the elders and the others would be enough.
However, when they heard the grand elder's order, they naturally didn't dare to be negligent and flew over.
In an instant, the number of people outside the light screen increased by two to three hundred, and there were already a thousand people.
"Everyone, listen to my order. Fuse your essence, energy, and spirit with the formation. Pour all your magic power into the formation. We will kill these two people with one strike!" the grand elder continued to shout.
He knew very well that Li Yu couldn't withstand the attack just now.
Now that more disciples had joined in and everyone was working together, they could definitely kill him with one strike.
Even if they couldn't kill him, they could still severely injure him.
...
'Almost everyone should be here now!' Li Yu thought to himself.
As expected, life was like a play. It all depended on one's acting skills!
He had successfully tricked everyone from the Nether Demon School into coming over and fusing with the formation.
At this time, the light screen of the formation had become more solid, and the light was even more dazzling.
The powerful pressure was like a mountain pressing down on the top of their heads.
Even some of the buildings below were creaking as if they couldn't withstand the pressure and were on the verge of collapse.
Heaven and earth shook as a dazzling purple light condensed in the sky. It was like a dazzling sun, making people unable to look directly at it.
The terrifying energy slowly condensed into a purple lightning dragon, which roared and charged toward Li Yu below.
Li Yu stood in front of Li Qingyun and didn't dodge. His right hand gripped the hilt of his sword tightly as he frowned slightly.
Whoosh!
The long sword slashed out, tearing the void apart.
The purple lightning dragon instantly exploded, turning into a dazzling light that spread in all directions.
The space trembled, and energy ripples surged out.
Everyone from the Nether Demon School looked expectantly at the center of the explosion.
This was the most powerful attack that had gathered all of their strength and exhausted all of their Dharmic powers. It should be enough to kill him.
Even if he was lucky enough to survive, he would definitely be severely injured and spit out blood.
However, when the light dissipated, Li Yu stood in the same place as before, his expression normal.
That was the strongest attack that had gathered the strength of more than a thousand people from their sect and the power of the protective formation.
It was the strongest attack that could flatten a mountain and kill a Void Interpretation Stage expert.
It had actually hit him!
How was that possible?
He was unscathed!
Was he a monster?
Everyone's hearts were filled with horror and shock!
However, at this time, Li Yu looked at everyone above, and the corners of his mouth suddenly curled into a … thought-provoking smile.
Then, he slashed out with his sword!
This slash seemed to have cut through time!
Everything was silent, and space seemed to have stopped for a moment.
However, in the next second …
Boom!
The light screen of the formation exploded.
