The seal of the demon's den opened. Behind it stood a group of demons.

The latter watched on anxiously.

They looked at Lin Jiufeng and the delicate-looking woman whose stature was reminiscent of that of a blood-red flower.

Her name was Queen Scarlet!

She was the one who contacted some top demonic cultivators and built this demon's den.

Then, she brought many demons under her wing and occupied the Land of Extreme Negative Energy. Now that the other demons in the demon's den had been defeated by Lin Jiufeng, it was her turn for the final day.

She had a beautiful figure, a bright dress, red hair, and a pair of charming eyes.

She was a peerless beauty.

The allure of a woman was vividly reflected in her image.

Every frown and smile she made carried extreme temptation.

This woman was dangerous.

"Why did you defeat us all one by one before letting us out?" Queen Scarlet asked.

"It is not in my original plan…"

"Defeating you all is enough, there's no need to continue suppressing all of you here. Without you demons, the world will be less exciting," Lin Jiufeng replied. After he defeated all of them, his signing in here would be over. Then, why should he keep these demons here?

In addition, they were the ones preventing him from further exploring the Land of Extreme Negative Energy!

"Aren't you afraid that we will go out and bring disaster to this world?"

"After all, we were pretty popular in the previous era." Queen Scarlet stared at Lin Jiufeng with her eyes that looked like they could speak a thousand words.

But Lin Jiufeng's heart remained as calm as still water.

His mind was focused solely on his cultivation.

Hearing Queen Scarlet's question, he directly shook his head and said, "If you lot brought disaster to the world and wantonly slaughtered people, I will find you all…"

"As long as you lot aren't confident in defeating me, then don't cause too much trouble and don't kill the common people, that's my only request."

The demons looked at Lin Jiufeng.

Then, they remembered these words in their hearts.

They might not be able to defeat him for the time being, but that didn't mean that they wouldn't be able to defeat him forever. After they left, they would absorb the spiritual energy and recover their previous strength. They would definitely become stronger than Lin Jiufeng.

Then, they would come back for revenge.

Lin Jiufeng cultivated painstakingly on his own.

In terms of cultivation speed, he was absolutely no match for them who only needed to absorb the spiritual energy in the air to recover their original realms.

Queen Scarlet thought so too.

She still wanted to ask Lin Jiufeng something, but Lin Jiufeng didn't give her the chance.

"You are the last. Once I've defeated you, I will let you all out," Lin Jiufeng directly said.

Queen Scarlet stiffened and replied, "It's already the last day. Can't you just skip the beating?"

If Lin Jiufeng injured her now, she would have to treat her injuries first before she could recover her strength after she came out.

She had been stalling for time because she wanted to escape this vicious beating.

Because of this—she had to put down her status and secretly sent flirtatious glances to Lin Jiufeng—who was thousands of years younger than her.

She was just short of saying what was on her mind.

But Lin Jiufeng still wanted to hit her?

"Hurry up. Only after I defeat you will it be a complete process. Only then will I be able to let you all out. Otherwise, none of you will be able to leave," Lin Jiufeng said indifferently.

Defeating Queen Scarlet would give him a chance to sign in.

Would Lin Jiufeng's heart soften because she was sending him loving looks through her eyes?

She was underestimating him too much.

Queen Scarlet secretly gritted her teeth.

A trace of helpless anger appeared on her beautiful and demonic face.

Lin Jiufeng completely rejected her.

Behind her—more than 3,000 demons eagerly watched on.

They were just short of telling her to take the initiative and quickly let Lin Jiufeng defeat her so as not to waste everyone's time.

Only after everyone was defeated would they be released…

Now that only Queen Scarlet was left, how could she escape this treatment?

"Then, let me experience how powerful the peerless genius of this era is."

Queen Scarlet gritted her teeth.

Her delicate body flew up, and millions of flowers bloomed with a raise of her hand.

The flowers flew towards Lin Jiufeng as she attacked with all of her might.

She wanted to test just how powerful Lin Jiufeng was right now.

However, Lin Jiufeng didn't even look at her.

He merely flipped his palm and pressed down gently.

Boom!

Inside the demon's den, a terrifying pressure manifested and directly bored down.

It suppressed Queen Scarlet's body in the blink of an eye.

The millions of flowers directly withered and fell. They couldn't even completely bloom before they dissipated under this strike.

Boom! Boom! Boom!

Queen Scarlet directly smashed onto the ground of the demon's den. Her defeat was just like the other demons. Lin Jiufeng had no intention of showing mercy to the fairer sex at all.

He attacked the same way and with the same sense of ease.

Pu!

Queen Scarlet spat out a mouthful of blood.

Her eyes were filled with horror as she looked at Lin Jiufeng in disbelief.

"You actually broke through—"

Queen Scarlet tried her best to suppress her surging blood and vital energy.

She felt extremely uncomfortable. She had just found out how strong Lin Jiufeng was right now.

Then, she herself couldn't believe the answer.

If it was true, then wasn't it too terrifying?

How could there be a terrifying genius like Lin Jiufeng in this world?

"What did he breakthrough into?" A demon asked Queen Scarlet curiously.

"That's right, isn't he at the Grotto-Heaven Realm?"

"Could he already be at the tenth level of the Grotto-Heaven Realm?"

"I feel that he has already reached the tenth level, right?"

"Yes, it should be about time. He should be at the peak of the Grotto-Heaven Realm by now."

The demons spoke one after another as they discussed.

Queen Scarlet smiled bitterly and replied, "He's already a… Supremacy."

As soon as these words fell, the demon's den instantly fell silent.

The demons felt as if they were struck by lightning.

None of them could sit still anymore.

"Supremacy?"

"Queen, don't talk nonsense. When he defeated us for the first time ten years ago, it was still very difficult for him to deal with us. At that time, he had clearly just entered the Grotto-Heaven Realm."

"That's right. In the past ten years, he has gone from the initial step of the Grotto-Heaven Realm to the peak of the Grotto-Heaven Realm. This is already a miracle. Even at the peak of the previous era, there weren't many people who could replicate this feat."

"Queen Scarlet—you said that he has made a breakthrough into the Supremacy Realm, you can't just scare us like this."

"If he really managed to cross the gap between just entering the Grotto-Heaven Realm and reaching the Supremacy Realm in just ten years in this early stage of the spiritual energy's recovery period, then it would really be heaven-defying…"

"Not to mention anything else, he might even be able to become an Immortal."

The demons spoke one after another, announcing the shock in their hearts.

The knowledgeable demons were shocked by Queen Scarlet's words.

This proved just how exaggerated Lin Jiufeng's actions were.

Queen Scarlet watched as everyone started their own discussions.

She raised her hand, her snow-white and slender jade-like hand mimicking Lin Jiufeng's gentle push just now.

"He defeated me with a casual push, and what he used was the Supremacy Realm's domain…"

"His aura is very powerful."

"Although he did his best to hide it, my realm has long surpassed that of the Supremacy Realm."

"How can I sense it wrongly?"

"He's a Supremacy!"

"He's the number one person in the world today!"

Queen Scarlet firmly declared.

The demons in the demon's den looked at Lin Jiufeng who was at the entrance.

Their eyes were filled with shock, and they found it hard to say anything.

Was he still human?

But Lin Jiufeng didn't even look at the demon's den.

He directly ignored the discussions down below.

He focused on his own matters.

"Sign in!"

After defeating Queen Scarlet, Lin Jiufeng immediately signed-in.

"This is the last time I'll be signing in at this demon's den…"

"The reward should be very good, will it be?" Lin Jiufeng looked forward to it.

[Sign-In successful. Received All-Heaven Star Sword Array!]

In an instant, Star Swords appeared in front of Lin Jiufeng.

The Star Swords were long and straight.

Their surfaces reflected the myriad stars in the starry sky.

Obviously, they were tremendously powerful.

He received more than 3,600 Star Swords.

Their sheer numbers had filled the entire underground palace.

Lin Jiufeng looked in surprise.

He looked at the 3,000 plus Star Swords and reached out to grab one of them.

Then, he twirled the sword in a pattern, testing its performance. The sword was light and it carried the radiance of the stars which surrounded Lin Jiufeng's figure in a mystical mist-like light.

"Not bad!" Lin Jiufeng was overjoyed.

He took out the sword case and stored every Star Sword in it. He wanted to nourish and increase their quality with the help of the sword case.
