171: The madman Li Wudi, a great battle is about to break out!

Invincible Li smiled and ignored the evil demon. He just said to himself, "Old friend, if you don't want to believe it, then continue to stay here!"

"I'm leaving now. If you decide to come out, just find me at our usual spot!"

After Invincible Li finished speaking, he turned around elegantly and then took out an ancient book.

He was not in a hurry to leave; instead, he seemed to be deliberately waiting for the Demon Dao Domain's Quasi-Emperors to come to him.

"You bunch of demon brats, you can worry about the rest of this yourselves!"

As Invincible Li watched the auras of the Quasi-Emperors getting closer, it was time for him to activate the void book and leave this place.

Invincible Li calmly poured his true essence into the void book.

'...'

However, the spatial channel he had imagined appearing behind him did not materialize.

Instead, he was enveloped by an invisible force, preventing him from using the void book to open an escape spatial channel.

Invincible Li immediately lost his composure.

"How can this be? Is space sealed? The void book cannot be used?"

"How is this possible? Quasi-Emperors can't do such a thing!"

"Who's nearby! Come out!!!"

Invincible Li was genuinely flustered this time; he had actually been set up.

He shouted at his surroundings, wanting to find the person who had tricked him.

However, Su Ningxue was not that foolish. She hid in the dark, quietly watching the frenzied and deranged Invincible Li.

Just then, an angry roar came from the sky: "Quick! That little thief hasn't left yet, hurry and catch him!"

A peerless demon with prominent horns stepped on the Void Realm, his gaze as sharp as a blade. From afar, he had already locked onto Invincible Li.

The other several Quasi-Emperor powerhouses who had rushed back from the Sword Qi Great Wall also arrived one after another.

They also saw Invincible Li, their faces all grim and cold.

"What a Human Race, what a Human Race! They are so despicable, on one hand claiming to fear war, and on the other, taking advantage of our absence to send people into our Demon Dao Domain to cause trouble!"

"Damn Human Race, they actually want to take advantage of the chaos to release this evil demon. Does the Human Race not want to live? Do they not know how dangerous these evil demons are?!"

"..."

Each demon spoke with righteous indignation.

Invincible Li's actions also brought trouble to the Human Race.

"Charge! Catch him!" a demon roared. The other Quasi-Emperors dared not be negligent or underestimate Invincible Li, simply because they could not see through Invincible Li's cultivation.

And since Invincible Li dared to trespass into the Demon Dao Domain alone, his strength must not be simple. Perhaps this person was also a Quasi-Emperor, just like them!

At this moment, Invincible Li was locked down by several Quasi-Emperors, and he found that he couldn't move.

"Damn it!!!"

"Who exactly is scheming against this Venerable One? Don't let this Venerable One find you, or I will make you taste the most severe torture in this world!"

Invincible Li shouted.

Immediately after, his appearance rapidly aged, and his vitality quickly weakened.

He was actually burning his essence to forcibly activate the void book.

Ning Rushuang looked at Invincible Li, a hint of surprise flashing in her eyes.

"This kid is really amazing, so ruthless to himself!"

"With this, he has burned at least ten thousand years of his Lifespan!"

Ning Rushuang watched Invincible Li, who, by burning his Lifespan, forcibly activated the void book, causing it to open a spatial channel.

"Not good! He's trying to escape! Quickly Seal the space, we can't let him get away! If he leaves with the treasure, and without the treasure to suppress the evil demon, our Demon Dao Domain will be finished!"

"No! The item in this person's hand is also a supreme treasure. Our Quasi-Emperor strength alone cannot Seal this space!"

The Quasi-Emperors of the Demon Dao Domain panicked.

At this moment, Invincible Li grinned at them.

"Everyone, this Venerable One will remember today's events. When this Venerable One returns, you will surely pay the price for what happened today!"

Invincible Li, now very old, said in an extremely hoarse voice.

After speaking, he stepped into the spatial channel.

"Bang!" The spatial channel closed, and Invincible Li, surrounded by many Quasi-Emperors, disappeared from the demons' sight!

"Revered Master! Invincible Li has left. What should we do now?"

Su Ningxue asked with a grave expression.

Now that Invincible Li had left with the treasure, this sealed land, without the treasure to suppress it, the Extraterrestrial Demons would break free before long.

Ning Rushuang sighed, "This Revered Master also doesn't know. Perhaps we can only find Invincible Li and snatch back the supreme treasure from him to continue suppressing that Extraterrestrial Demons!"

"Let's go, girl. It's time for us to return!"

Ning Rushuang also quietly opened a spatial channel. Before the demon Quasi-Emperors noticed them, they quickly left the Demon Dao Domain and returned to the Sword Emperor Dao Domain... At this moment, in an obscure small place within the Sword Emperor Dao Domain.

A spatial channel suddenly opened, and a white-haired figure, holding a jade stone, emerged from it.

His aura was extremely weak at this moment, like a dying person.

With every step, he had to gasp for air.

"Damn it! Who exactly is scheming against this Venerable One? If not for someone sealing that space, this Venerable One wouldn't have had to burn ten thousand years of Lifespan to forcibly activate the void book and leave that place!"

Invincible Li frowned, pondering who had harmed him just now.

Anyone capable of sealing space and rendering the void book unusable for a short period must be incredibly powerful.

Quasi-Emperors couldn't do it.

Even Great Emperors could only barely control it for a few breaths.

To Seal space for an extended period, rendering the void book unusable, such strength could only belong to an Immortal.

But, Immortals?

Immortals don't exist in this world!

Invincible Li felt increasingly exhausted the more he thought. The mental effort required for thinking now was far greater than before.

Suddenly, a figure flashed through his mind.

It was the figure he had seen in the Sword Emperor Dao Domain just before he went to the Demon Dao Domain.

"Could it be that woman?" Invincible Li thought of Su Ningxue.

That woman gave him a strange feeling. He had a thought that it was Su Ningxue who had secretly tricked him just now.

"Whether it's that woman or not, I'll have a way to confirm it when I see her!"

"For now, I should quickly find a treasure to recover this depleted Lifespan!"

As Invincible Li spoke, he dragged his weary body, relying on great perseverance, towards a certain place... On the other side, more soldiers had gathered on the Sword Qi Great Wall after the Thirteen Great Battles.

Originally, after the Thirteen Great Battles ended and the Sword Emperor Dao Domain won, it should have been a day of celebration for the whole world. However, a change occurred in the Demon Dao Domain, and the people of the Demon Dao Domain blamed all these changes on them.

Now, war is on the verge of breaking out!
