"We've already gone at least a thousand feet deep. Is this demonic cave leading straight to the Earth's core?"

Feeling the increasing pressure around him, Lin Jinglong felt like he was being squeezed into a ball. If it weren't for his physical body, he would have already reached the level of transcendence.

He couldn't possibly go deep into this place.

Not to mention, the demonic energy washing over him became increasingly solid, almost becoming tangible.

The deeper he went, the more difficult it became.

Along the way, Lin Jinglong traversed several underground palaces, which showed signs of extensive human activity. However, these underground palaces were merely nodes in the passageways, not the true end of the demon's lair.

He didn't reach the end of this demonic cave until he had truly gone deep underground, thousands of feet below the surface.

In the last main hall, or rather, in a small cave that could hardly be called a main hall, he finally achieved his goal.

"call!"

Lin Jinglong breathed a sigh of relief.

Finally, we've arrived at this final end.

Along the way, if he hadn't mastered the power of the Heavenly Dao, tamed the origin of the Heavenly Demon, and possessed an incredibly strong physique, he would have been in a very difficult situation.

Otherwise, his will would have been devoured long ago, assimilated into a true demonic body, or his body would have been devoured.

At this moment, he looked at the scene ahead.

But he showed a strange expression.

"Another sword in the stone?"

He once obtained the Supreme Sword from a spirit crystal and, through the people of the Supreme Pavilion, acquired the Supreme Body Forging Method, ultimately achieving his own Supreme Body.

At this moment, he was on a dark rock.

I saw an ancient sword stuck in it!

This sword is as black as ink and has an ancient design.

All the demonic energy in this place emanates from this sword.

"The source of demonic energy that could affect the entire Northern Region was just an ancient sword."

Looking at the black demonic energy that was washed out, the demonic energy that had solidified into a tangible form made it almost impossible for Lin Jinglong to open his eyes.

The only option is to forcibly probe using one's own divine sense.

But when his consciousness landed on the demonic sword, he felt a surge of exhilarating will.

"Is the mysterious attraction coming from this demonic sword?"

Lin Jinglong revealed a mysterious smile.

He understood that once he mastered the essence of the Heavenly Demon, he would stray further and further down this path.

There was always a unique force attracting him.

"I was actually tempted by a sword."

Lin Jinglong shook his head helplessly.

The sword drew him closer from the depths of his soul, causing Lin Jinglong to almost instinctively raise his hand and grab the hilt.

It looked as if he had picked up an item that he had been with for many years, very naturally and skillfully, without the slightest discomfort.

Just like this sword, it was born to belong to Lin Jinglong.

Even he himself perceived it in this way.

At the same time, the dark ancient sword, which contains a large amount of demonic energy, seems to have the same thought hidden within it.

After Lin Jinglong successfully grasped the sword hilt.

The gushing demonic energy finally seemed to stop, but it did not cease to be released.

Instead, it was all poured into Lin Jinglong's body.

This is a terrifying power capable of influencing the entire Northern Region, and at this moment, this power is surging wildly into Lin Jinglong's body.

It was as if it wanted to take over his body, blood, and even soul.

Hahahaha!

A sharp, strange laugh echoed in Lin Jinglong's mind; it was the will hidden within the demonic sword.

"After all these years, I've finally found the best host. Does this Demon Lord finally have a chance to leave this wretched place?"

The being hidden within the demonic sword, constantly tempting Lin Jinglong, seemed somewhat carried away by its own smugness.

Lin Jinglong continued to grip the ancient sword, unsurprised by this.

He had already noticed it, but...

"Trying to possess me, huh? Anyone who's tried that before is probably already overgrown with weeds!"

Lin Jinglong let out a mocking laugh.

If it were any other controller of the Heavenly Demon Origin, even if it were Zhang Shentong or Lin Ruchu, even if they had the chance to enter this place and seize this demonic sword, being possessed would only be a matter of a moment.

Because they had long since assimilated with the demonic essence within them and merged with the demonic path!

If that's the case, then it's only natural that this self-proclaimed Demon Lord, as the true controller of the Heavenly Demon Origin, would possess them and control everything about them.

But Lin Jinglong has never followed the usual path.

He did not merge with the origin of the Heavenly Demon; he merely used his incomparably powerful bloodline talent to forcibly tame the origin of the Heavenly Demon.

"You and I should be on the same level, or even that you should be below me. What right do you have to try to control me?"

Lin Jinglong let out a mocking voice in his mind.

Why...why are you like this?

The Demon Lord let out a scream.

He also realized that although he poured a large amount of demonic energy into Lin Jinglong's body, he found that the guy was not assimilated by his will, but instead was continuously controlling the demonic energy.

In other words, Lin Jinglong is indeed an existence of the same order as him, and these demonic energies are merely his nourishment, unable to assimilate Lin Jinglong.

"There are no so many whys, it's simply because I was born invincible!"

Lin Jinglong has never been able to truly explore the secrets of his bloodline. He once thought that he was born with imperial blood and that he could achieve the body of a Martial Emperor as long as he followed the steps.

Even the reclusive Lin family members thought so.

However, later, even the Lin family discovered that compared to Lin Jinglong, Tian Sheng Di Xue was not even as good as a stray dog ​​on the roadside.

His bloodline was so powerful that it was beyond comprehension.

Later, Lin Jinglong believed that he was born with a Daoist physique.

He has a unique connection with the Heavenly Dao, which is why he can wield the power of the Heavenly Dao even without conforming to it.

But after that, Lin Jinglong discovered that his bloodline, in addition to the Heavenly Dao, could even suppress the Heavenly Demon Origin and forcibly suppress and tame it.

This clearly transcends the scope of the innate Dao body.

"Invincible Bloodline!"

Lin Jinglong couldn't imagine it.

The progenitor who originally possessed this bloodline, Lin Wudi, was an exceptionally talented individual in ancient times.

But at the same time, he was also wondering whether Lin Wudi, with his invincible appearance, had already won the battle for the Heavenly Dao and achieved immortality.

He was distracted by his thoughts.

The true demon who was trying to seize his body was now in a state of despair and shock, realizing that his will was indeed being suppressed by Lin Jinglong!

His control over his own power is also being gradually stripped away.

A sense of powerlessness was spreading through his consciousness!

Meanwhile, Huangfu Kong and the others outside were looking at each other in bewilderment, with the Xuanling Mage going to Lan Yuexin's side.

"Palace Master Lan, the demonic energy suddenly stopped. Was this also within the expectations of your Demon-Slaying Palace?"
