In the past five years, the outside world has been turbulent, including the Yuhua God Dynasty.

Only the Cold Palace remained the same.

It hasn't changed that much in the past five years.

However, some parts of the Cold Palace's outer walls had fallen off, revealing the mottled inner walls that showed its fight against time.

Some dilapidated houses in the Cold Palace had collapsed.

This Cold Palace had a history of more than a hundred years.

No one had renovated it for a long time, so it wasn't out of the ordinary for some part of it to collapse.

Fortunately, the courtyard that Lin Jiufeng chose was relatively clean and comfortable.

He didn't plan on switching to another courtyard.

After five years, he had long absorbed the Grotto-Heaven Great Pill and expanded his Divine Grade grotto-heaven.

He truly stood at the peak of the Grotto-Heaven Realm by now.

Ten years ago, he made a breakthrough into the Grotto-Heaven Realm and formed a Divine Grade Grotto-heaven.

Ten years later, he finished absorbing the Grotto-Heaven Great Pill and stood at the pinnacle of the Grotto-Heaven Realm.

In the past ten years, the only change was that Lin Jiufeng had more or less defeated most of the demons, Demon Kings, and Demon Gods in the demon's den beneath the underground palace.

These 3,000 plus powerhouses from the demon's den were reputable powerhouses in the previous era. Every one of them were extremely terrifying existences that stood at the top when it comes to power in their own demonic sects.

But in this brand new era, they had gotten trapped in the demon's den where they sealed themselves for hundreds of years and effectively became Lin Jiufeng's Monster Spawner.

One per day.

365 per year.

After 10 years, Lin Jiufeng had defeated about 3600 demons from this demon's den.

There were only about 10 demons that Lin Jiufeng hadn't defeated yet.

The things that Lin Jiufeng received were mostly different.

Most of them were demonic cultivation techniques.

There were also some other treasures.

For pills, Lin Jiufeng directly consumed them.

The pills that he couldn't eat or were useless to him were then fed to the white cat.

The white cat became a peak Human God just from consuming those pills.

She was originally an ordinary cat, but after obtaining a heaven-defying opportunity and consuming the pills of the Demon Lord, she became a Martial Sage.

But her cultivation speed after that had become extremely slow because her foundation was relatively weak.

But even so, after being nurtured by Lin Jiufeng's vast amounts of pills and treasures, she still managed to reach the peak of the Human God Realm—the Nirvana stage.

From this, one could see how many treasures Lin Jiufeng had received from signing in for the past ten years that passed.

On this day, Lin Jiufeng came to the demon's den early in the morning.

After five years, Lin Jiufeng was already in his sixties, close to turning 70.

Thinking carefully, he realized that he had been in the Cold Palace for almost 50 years now.

50 years…

This was a large part of an ordinary mortal's life, and Lin Jiufeng had just spent it in the Cold Palace alone.

It was all thanks to his character that he managed to do so.

Ordinary people couldn't possibly endure staying here for so long.

He was almost 70 years old, but he looked just like a teenager.

His eyes were as bright as the stars and his teeth were pearly-white.

He looked just like an elegant and handsome teenager.

The white cat didn't change that much either.

But her fur became even more radiant and soft.

One could also feel a trace of nobility to it.

A single look was all it took for anyone worth their salt to know that the white cat had a formidable bloodline.

But in Lin Jiufeng's eyes, she was just an abandoned stray cat.

"Why are you always going down there every day to fight them? Is it fun torturing them?"

The white cat followed Lin Jiufeng and asked, puzzled.

"Am I torturing them?" Lin Jiufeng asked.

"Yup. You always defeat them with one slap every day." The white cat nodded.

She was thoroughly confused.

Lin Jiufeng thought for a while and replied, "I won't be able to do this to them any longer."

Out of the 3,000 plus Demon Gods, only ten of them remained useful to Lin Jiufeng.

10 days later, Lin Jiufeng wouldn't go to the demon's den anymore.

By that time, even if the demons begged him to come, he wouldn't pay them a visit.

Speaking of this, Lin Jiufeng was a little downcast.

This Monster Spawner was about to lose its effectiveness.

He would no longer have the advantage of repeatedly signing in there.

He had to start looking for other places to repeatedly sign in after ten days.

Lin Jiufeng was frustrated.

In the end, he directly visited the demon's den. With a light tap of his toes, the seal of the demon's den vanished. The 3,000 plus demons below looked at the final 10.

Lin Jiufeng hadn't defeated these remaining 10 yet.

The other demons had been taught a harsh lesson by Lin Jiufeng.

Compared to 10 years ago when they were indignant and angry…

They had already resigned themselves to their fates after so many years had passed.

They stopped fantasizing about Lin Jiufeng letting them out as they watched on as he became stronger and stronger. They watched as they remained sealed, unable to absorb the spiritual energy of the outside world.

Then, they watched as the gap between them and Lin Jiufeng continued to widen.

The 10 demons who were being watched by everyone felt a myriad of emotions surging in their hearts. They felt extremely bitter.

"Damn it, we can't beat him in a fight, yet we must still fight him. How annoying."

One of the remaining 10 cursed.

The others remained silent.

"It's been 10 years. In these 10 years, we've personally witnessed his terrifying strength from the moment he entered the Grotto-Heaven Realm until today. I reckon he is now at least at the peak of the Grotto-Heaven Realm. His improvement is simply too fast," A Demon God cried out.

"I even suspect that he has broken through to the next realm."

"Wu, wu, wu~"

Real men never shed tears easily, unless they were truly heartbroken.

They were continuously suppressed by Lin Jiufeng for 10 whole years now.

These 10 years didn't pass in a blink of an eye. It involved a painstakingly torturous daily routine where every day, one of them would be beaten up by Lin Jiufeng. Counting the days since he started beating them up, about 3,000 plus days have passed since then.

"Back then, I was really not afraid of anything. Even when the Daoist priests from Quan Zhen Sect provoked me, I still dared to kill and rob them." A Demon King couldn't hold it in anymore and revealed his glorious deeds.

This was his proudest moment.

"At that time, the Quan Zhen Sect was very terrifying, they were a sect which even had Immortals at their peak. Even so, I dared to make a move on them. Who would have thought that I would have such a depressing day today?" The Demon King said indignantly.

"That's right…"

"In the previous era, who doesn't know of my great name, Demon King Pingtian?"

"I was one of the Seven Great Sages of the Monster and Demon Race!"

"I even participated in the construction of this demon's den and I did my best to make sure that it is built to last and will be able to maintain its stable state against the test of time!"

"Now, I've actually trapped myself inside my own creation. I have essentially played myself."

Demon King Pingtian was quite angry about this.

It was only in the end that he realized that the clown was actually himself.

The other demons were speechless.

What he had done was really akin to digging his own grave in hindsight.

Peng! Peng! Peng!

Lin Jiufeng knocked on the ground on top.

A continuous sonorous sound rang out.

Lin Jiufeng then announced.

"Don't reminisce about the past anymore. Hurry up and make your move!"

"I'll fight it out with you!" A Demon King in the form of a Tauren roared angrily.

He directly charged upwards to fight it out with Lin Jiufeng.

His aura was extraordinary and he had the strength of a peak Human God Realm expert.

In fact, his realm faintly seemed to have surpassed that of the Human God Realm.

In the demon's den that had been sealed for thousands of years, he was definitely a top existence.

But Lin Jiufeng only stretched out his palm and pushed it downwards.

Boom!

The massive force behind his palm suppressed the Tauren Demon King.

The shockwave exploded on his body and he was sent flying onto the ground like a kite with its strings broken.

He ended up heavily injured in the ordeal.

And even so, this result was Lin Jiufeng showing mercy and not killing him.

When the other demons saw this scene, they shook their heads in regret.

"He's even stronger now." A Demon God muttered.

He felt extremely bitter. He really wanted to go out.

But Lin Jiufeng didn't give him the chance to do so. He directly sealed the demon's den.

Then, he signed in.

[Sign-In successful. Received Sword Driving Technique!]

Lin Jiufeng's eyes lit up as he said in surprise, "Is this the Sword Driving Technique that can kill enemies thousands of miles away?"

[The range of the Sword Driving Technique depends on the strength of the caster. Moreover, the Sword Driving Technique only has one strike. If it cannot kill the enemy, the caster can only proceed to re-execute the strike.]

The last sentence was vague, but Lin Jiufeng knew that the opponent would most likely be able to dodge the re-execution of the strike.

"This isn't so bad either. With this Sword Driving Technique paired with my sword techniques, I will be invincible," Lin Jiufeng muttered.

Lin Jiufeng didn't expect that the rewards close to the end of his routine would be this great.

With the Sword Driving Technique in hand, Lin Jiufeng was reluctant to leave the demon's den and the 3,000 plus demons inside.

If only he could sign in using each of them twice, how great would that be?

He would definitely cherish that opportunity until the very end!
