"I fight better when there's nobody around me since I can let loose without needing to worry about hitting you guys as well," Yuan said to them.

"I-I understand… If you think you can defeat it by yourself, we won't get in your way. But if I sense that you're in danger, I'll immediately assist you." Grandpa Lan said to him before returning to his human form.

"You want to fight me alone? Hahaha! Don't get cocky just because your cultivation improved slightly! You're still only a Spirit Grandmaster whilst I am a Spirit Lord! There's still a vast gap between us!" The Demon Lord laughed as its aura continued to rise.

Yuan didn't wait any longer and rushed at the Demon Lord, striking it with his Empyrean Overlord.

Clang!

The Demon Lord used two of its swords to block Yuan's strike whilst using its third one to retaliate.

Yuan then used his movement technique to dance around the Demon Lord. Despite being an entire realm above Yuan, the Demon Lord still had its movements suppressed by the Heavenly Domain.

"What an annoying movement technique!" The Demon Lord didn't dare to waste its movements while being restricted and waited for Yuan to strike, as a single mistake might cost its life.

[Bloody Sword Strike!]

Yuan suddenly attacked the Demon Lord after a minute of trying to confuse it with his movement technique.

However, even though the Demon Lord couldn't move at its full speed, its reaction remained in peak condition, allowing it to defend against Yuan's strike even though its movements were slowed.

The two of them continued to dance back and forth with Yuan being on the offensive and the Demon Lord on the defensive for many minutes.

'Fuck! How long can he keep this restriction domain active?! How much spiritual energy does he have?!' The Demon Lord cried inwardly, as it had been waiting for Yuan to exhaust his spiritual energy.

After all, to sustain such a powerful pressure that could restrict even a Spirit Lord's movements, it would obviously require an immense amount of Qi.

However, many minutes have passed without any signs of Yuan exhausting his spiritual energy.

Half an hour later, the Demon Lord roared, "Don't tell me you have unlimited energy as well?!"

The Demon Lord decided to risk it and flew into the sky, where the Heavenly Domain could not reach him.

Yuan narrowed his eyes at the Demon Lord in the sky. Although he could also fly, he wasn't confident enough in his flight abilities to fight someone like the Demon Lord in the skies.

"Blood Spears!"

The Demon Lord suddenly summoned a dozen spears with its blood before throwing them at Yuan.

Yuan immediately used his movement technique to dodge them, but the Demon Lord continued to summon the spears, raining them down on him.

"You think you're the only one with inexhaustible spiritual energy?! I can do this all day!" The Demon Lord laughed as it continued to throw spears at Yuan from the sky.

Hundreds of spears later, Yuan left the ground and flew into the air as well.

"So you've finally decided to fight me!" The Demon Lord said as it summoned its swords and flew towards him.

Clang!

The two of them clashed in the air, causing the clouds around them to ripple away.

"You fell for it, human!" The Demon Lord suddenly grinned.

The next second, two more arms appeared behind the Demon Lord's back, preparing to strike Yuan at any moment now.

"Let's see if your movement technique works in the air!"

However, Yuan remained calm despite the Demon Lord's surprise.

And right as the Demon Lord moved its arms, Yuan's eyes glowed golden, causing the Demon Lord to halt for a split second.

In this split second, Yuan used the invisible Starry Abyss to create a hole in the Demon Lord's face, taking it by surprise for a second time.

And with his third strike—

"Demon Sealing Strike!"

Yuan used this chance to stab the Empyrean Overlord in the chest.

"He did it!"

The Lan Family watching from afar trembled in excitement after seeing Yuan successfully strike the Demon Lord.

"AAAAAH! DAMN YOU!" The Demon Lord shouted in rage after realizing that Yuan had managed to injure it successfully.

Normally, it wouldn't react even if it had its entire body crushed into meat paste, but a single strike from someone with a demon sealing technique is akin to death no matter how minor the injury! Hell, even an injury as small as a paper cut will seal a demon's fate!

This is why the demons feared the Demon Sealing Clan so much. If they so much as bump into their swords, it would mark the end for the demons.

After his successful strike, Yuan immediately retrieved his sword and distanced himself from the Demon Lord, running back to the Lan Family just in case.

"Fuck! Fuck! Fuck!

The Demon Lord didn't even bother to chase after Yuan and instead began digging a hole in its own stomach with its bare hands, trying to rip away the injury created by Yuan.

But alas, the Demon Lord soon realized that its efforts were in vain since the petrifying effects eventually began to spread throughout its body.

"No! No! No! It can't end here! It can't! I still have to leave this godforsaken world and rule the outside world! I cannot die here!" The Demon Lord began shouting like a maniac who'd gone crazy.

Who could've thought that after struggling for hundreds of thousands of years, the Demon Lord would succumb to a human who, logically speaking, shouldn't even have the qualifications to face it.

Unfortunately for the Demon Lord, Yuan was someone who transcended all logic and common sense even in the cultivation world where almost anything can happen.

"If I die… I will take at least one of you with me!!!" The Demon Lord suddenly flew towards their direction with its eyes bright red and a resolute expression.

Seeing this, Grandpa Lan suddenly shouted, "Shit! It's planning on blowing itself up! If we're caught in that, we'll be in grave danger!"

"What?! It can do something like that?!" Yuan exclaimed.
