Lin Jiufeng had no idea that even though he rarely left the Imperial Capital of the Yuhua God Dynasty and stayed in the Cold Palace most of the time, he still had a respectable reputation in the world.

And the ones who praised him the most were the group of demons from that demon's den.

The people of the world thought that the appearance of those demons back then signaled the end of the world and the start of a great massacre. But what happened in the end was contrary to everyone's expectations. The demons—they didn't dare to cause a commotion at all.

Everything remained as serene as ever.

With the appearance of the demons, the demonic sects rejoiced and their morale shot through the roof. They felt that this was the time for their demonic sects to prosper.

But who knew that the demons that had just emerged were timider than the demonic sects?

They didn't dare to confront the Yuhua God Dynasty at all. Each one of them chose to absorb the spiritual energy of the world in a low-key manner, they pretended as if they didn't exist in the world and kept their silence throughout.

The world definitely changed when they emerged.

But the world didn't seem to have changed that much on the surface.

Everything remained the same.

The Yuhua God Dynasty was still the same.

The common people lived and worked in peace, and the major sects and aristocratic families consolidated their strength silently.

They didn't dare to openly rebel against the Imperial Capital.

After all, there was a terrifying old monster in that Imperial Capital.

If they weren't confident that they could defeat that old monster, they would have to be obedient.

…

The one being referred to by everyone as an 'old monster,' Lin Jiufeng, observed the world in the next few days.

After he made a breakthrough into the Supremacy Realm, he released the demons and moved the underground palace away.

He shattered the demon's den beneath the underground palace and saw the true Land of Extreme Negative Energy.

Then, he suppressed the demonic energy in the Land of Extreme Negative Energy and acquired the [Light of the Homes].

He was in no hurry to explore the Land of Extreme Negative Energy.

Lin Jiufeng chose to observe the world for now.

He wanted to see if this group of demons had killed wantonly after they emerged into the world.

The realm after the Grotto-Heaven Realm was the Supremacy Realm.

Any expert in this realm would usually have an honorific name.

But Lin Jiufeng didn't give himself a so-called honorific name.

He just wanted to continue his daily routine in peace and silence.

He didn't need an honorific name.

'I made a breakthrough into the Supremacy Realm and turned my Grotto-heaven into a domain. On that rainy night, my metamorphosis was completed.' Lin Jiufeng looked up at the sky.

The lights in his eyes were fierce.

Behind him, a vast world could be vaguely seen.

The world itself was a Divine Grade Grotto-heaven. It was Lin Jiufeng's Grotto-heaven that he had already turned into a domain.

Inside this domain, Lin Jiufeng's combat strength was doubled.

Under its limitless expansion similar to a universe—if his domain wasn't broken nor retracted—he would eventually become strong enough for him to be considered invincible.

Lin Jiufeng was currently observing the world.

He could see everything—from the changes in the auras coming from every cultivator as they made their breakthroughs into their next realms, the fluctuations in the tide of spiritual energy as it floated in the air—and the stench of blood left in the countless battlefields of the world.

If the demons dared to act recklessly, Lin Jiufeng would punish them from thousands of miles away.

Fortunately, the demons never made a move.

Of course, the world truly wasn't peaceful with the emergence of those from the previous era.

It was a good thing that the 3,000 or so powerful demons that emerged just recently had become a deterrent to these people. The powerful demons kept their silence and quietly recovered their strength.

Compared to the clowns that had just broken free from their seals and were now acting as if they owned the world—those that were truly powerful kept their silence and cultivated in peace.

After observing for a few days, Lin Jiufeng soon stopped his observation.

He believed that the demons would listen to him. He predicted that only when these demons had recovered their peak strength would they come to the Imperial Capital to defeat him.

Only then would they dare to bring a catastrophe to the world.

As a result, Lin Jiufeng's worry was alleviated.

He could finally go and explore the true Land of Extreme Negative Energy in peace.

It has been 50 or so years since Lin Jiufeng arrived in the Cold Palace. It has also been 50 years since he became a neighbor of the Land of Extreme Negative Energy.

From the beginning until now, he had unveiled layers of mysterious veils over the Land of Extreme Negative Energy.

From Imperial Consort Jia to the Chasing Corpse Sect, from the Chasing Corpse Sect to the Demon Lord 1,500 years ago, then from the Demon Lord to the demon's den beneath the underground palace.

Covered by layers of mysterious veils, the Land of Extreme Negative Energy appeared mystical and full of pleasant surprises.

Today, Lin Jiufeng arrived at the Land of Extreme Negative Energy early in the morning.

Deep underground, it was a place that was truly impossible for ordinary people to arrive into.

No one knew that there was a Land of Extreme Negative Energy here.

The cave system of the demon's den was winding and confusing, to say the least.

The Land of Extreme Negative Energy was situated even deeper than the demon's den.

It was like a hellish world, yet Lin Jiufeng came down alone without the white cat.

The white cat had been trying to make a breakthrough into the Grotto-Heaven Realm recently. With the resources that Lin Jiufeng gave to her, even though she wasn't talented enough, she still advanced rather quickly.

Entering the Land of Extreme Negative Energy, what greeted his eyes was not a battlefield, but a graveyard.

There were tombs connected to each other, and they were all made from the soil in the surroundings.

A small mound of soil with a tombstone.

Some of the tombstones were made of wooden planks. Most of them had already rotted away.

Lin Jiufeng saw a few broken weapons inserted into the soil of the Land of Extreme Negative Energy.

Broken swords, broken sabers, broken halberds, and even broken furnaces…

These were once powerful treasures, treasures that a few cultivators had nurtured throughout their entire lives.

But now, they had become nothing but scrap metal.

They were all corroded by the Land of Extreme Negative Energy.

Lin Jiufeng picked up a broken longsword that was at the edge of a small grave.

With a little strength, he pulled it out.

Then, the longsword disappeared with the wind.

All that was left in Lin Jiufeng's hand was dust.

"Time has rendered everything useless." Lin Jiufeng lamented.

He couldn't help but look at the stone tablet in front of the tomb.

There were no other words on it, only the name of the tomb owner was carved on it.

"Tomb of the Millennium Sword God of the old era!"

Lin Jiufeng muttered out the words.

"He should be one from the batch of powerhouses that Demon King Pingtian mentioned. One of those who sacrificed their lives fighting for the right to occupy the Land of Extreme Negative Energy," Lin Jiufeng said softly.

He prepared to leave and look at the other tombs…

But a line of words suddenly appeared before his eyes.

[Do you want to Sign-In before the grave of the Millennium Sword God of the old era?]

Lin Jiufeng was stunned.

He looked at the tomb of the Millennium Sword God, then at the boundless cemetery in the Land of Extreme Negative Energy. He couldn't help but smile.

It seemed that he had discovered another land of bountiful opportunities to sign in at.

"Sign in!" Lin Jiufeng agreed.

[Sign-In successful. Received Millennium Sword God's sword technique: Flying Sword Technique!]

An old man appeared in Lin Jiufeng's mind.

He held a wine pot in one hand and a sword in the other.

Crossing through the endless years, he showed his sword techniques to Lin Jiufeng.

It was a tremendously powerful sword technique.

Flying sword meant that it was a sword technique that didn't belong to the mortal realm.

The sword technique of the Millennium Sword God surpassed even Lin Jiufeng's current arsenal combined.

Lin Jiufeng became engrossed in the sword technique.

It wasn't until the Sword God was done executing a set of sword techniques and a sword light slashed over from thousands of years ago did Lin Jiufeng open his eyes.

Beaded sweat filled his forehead.

He felt the pressure from just now.

In front of the Millennium Sword God, the current Lin Jiufeng was still not strong enough.

But this fact didn't affect Lin Jiufeng. Instead, it ignited his excitement.

"Is this how strong a powerhouse from the previous era is?"

"This kind of swordsmanship is simply sublime. I can't ask for a more generous reward than this. I feel that I will have a chance of peering into a higher realm once I'm done learning this."

Lin Jiufeng was excited.

He had already reached the summit of what was possible in this era.

Even though the demons in the demon's den were all stronger than Lin Jiufeng in terms of cultivation realm, their strength was far inferior to Lin Jiufeng's.

The current recovery rate of the world's spiritual energy could only support a cultivator at the peak of the Grotto-Heaven Realm.

Lin Jiufeng forcefully pushed past this limit himself because he could sign in every day.

But compared to the true powerhouses of the previous era, he was not strong enough.

The Millennium Sword God truly inspired Lin Jiufeng and ignited his passion to become even stronger.
