The Final Story of the Past 2/2

A small smile appeared on Yuna's face when she heard these words. It's been a long time since someone swore to kill, so she couldn't help but chuckle in amusement.

"Hehe, it's been a long time since someone wanted to kill me. Just when was the last time that happened? Was it that annoying god-devouring dragon? Or maybe the leader of that world-destroying cult? *Sigh* It's been so long that I'm not entirely sure about the proper order of events anymore~"

The demon cultivator couldn't help but shudder a little when Yuna mentioned entities that the sect's previous ancestor had been telling him about like they were alive only a few years ago.

'For how long has this damn woman lived? This is ridiculous.'

Although he was slightly intimidated by Yuna's words, he didn't care in the end. After all, they were just empty words, and even if they were true, all that happened a long time ago, and Yuna was relatively close to her dying day, so she should be significantly weakened. For now, he was confident in his victory.

He flicked his wrist, causing a huge crimson halberd to appear in his hand, and, after seeing that her opponent had armed himself, Yuna grabbed the air, but before she could fully close her hand, a white sword hilt appeared out of nowhere which quickly grew into a full-fledge massive sword.

A frown appeared on the demon cultivator's face when he saw Yuna creating her weapon out of ice.

"Are you mocking me? Do you truly think a weapon made on the spot could handle my halberd?"

Yuna could only sigh deeply when she heard that comment.

"*Sigh* So the world has even forgotten how I fight, huh? Well, considering neither my disciple nor children managed to learn it, it might not be too surprising that my true fighting style has been forgotten."

The demon cultivator scrunched up his nose when he heard Yuna's words. Frankly, he couldn't believe that she didn't even use a proper weapon and had to use one made of her own ice instead.

'Is she trying to trick me? That is very likely, so I will have to be careful about what she is planning.'

Yuna could only shake her head when she saw her opponent's facial expression.

"Oh well, I frankly don't care whether you believe me or not. So, let's get in the proper mood, shall we?"

While Yuna closed her eyes and started concentrating, question marks popped up above her opponent's head.

'Proper mood? What is she even talking about?'

Moments later, Yuna reopened her eyes as an aura of utmost arrogance leaked out of her body.


An awkward silence followed Yuna's outburst, as the person in front of her looked at her in bewilderment.

'W-What was that just now? Venerable one? Courting death? What is she talking about? Wait, I remember! My grandfather once told me that his grandfather's grandfather said to him that old people would occasionally speak all weird. That must be it!'

Yuna frowned when she got no reaction to her proper greeting.

"What? Are you not going to answer me? *Sigh* Youngsters nowadays are so rude. Absolutely no manners at all."

Naturally, the middle-aged man in front of her had no clue what he was even supposed to say, so Yuna simply shrugged her shoulder and pointed her blade at him.

"This Venerable One has seven days of life span left, so this Venera... ahh f*ck it."

The arrogance radiating out of Yuna vanished instantly as she took a more relaxed posture.

"So, anyway, I'll make this flashy. I'll burn my remaining lifespan to deliver one devastating attack, so good luck surviving."

Also, her opponent was still confused due to yet another switch in mood; he quickly analyzed Yuna's words, and a massive grin appeared on his face.

"I see. An all-or-nothing gamble. Good, I like it. Let's do it."

In fact, he didn't get the position of the strongest demonic cultivator out of sheer luck; he was a very cautious man. So, he currently had over ten divine-level protection artifacts in his spacial ring. No matter how much power Yuna's last move had, activating one or two of these would block the attack no matter what.

Yuna nodded her head in approval as she allowed her aura to burst out of her body, causing space to shake as snow started slowly descending from the skies.

When he felt her power, a smirk appeared on the demon cultivator's face.

'Hehe, as expected, she had grown old. I might not even need to use one of my protective artifacts.'

However, before he could taunt Yuna, her aura grew even further, causing the space to tremble and distort while a snow storm started covering the continent they were on.

"Heeee~ Quite impressive. As expected of the world's strongest being. Even a mere seven days of your life grant that much power."

'Seems like I misunderstood. That first power burst was only her natural aura. How frightening. I might actually need to use multiple defense artifacts for this. However, it will be worth it.'

Yuna shook her head as she looked at her opponent with pity.

"I pity your ignorance, child. While your ancestors were still eating mud on the playground, I already sat firmly on the seat of the strongest, fighting gods and divine beasts in an era far less stable than this one. Do you honestly believe this pitiful amount of power is worth seven days of my life? That first power boost was merely me lifting the seal that prevents my presence from destroying my surroundings."

The demon cultivator's eyes bulged out when he heard Yuna's words. In fact, everyone spectating the fight had similar expressions. However, most of them immediately denied Yuna's words as a lie. They couldn't believe someone could become that much more powerful than them without using a sacrificial method.

Yuna saw everyone's facial expressions and could only shake her head.

"I see the doubt in your eyes, brats. Very well. Be honored to witness what is about to happen and burn it into your minds. Witness the strongest attack ever recorded in history. Witness... what seven days of my life are worth."

Then, Yuna's aura exploded even further, causing the space around her to crack due to the sheer weight of her presence while the whole planet was engulfed in a massive storm of snow and ice.

Instantly a massive thunderstorm gathered above Yuna, forming tribulation clouds as if her strength angered the heavens themselves. Unfortunately, those were frozen instantly and converted into more snow clouds.

Currently, there was nothing that could oppose Yuna.

Meanwhile, the demon cultivator had almost soiled his pants when Yuna unleashed her full power. Divine grade artifact would protect him? When he felt Yuna's aura explode, that idea turned into the equivalent of covering his body with a layer of one-layered toilet paper. There was only one choice. He had to run away.

"[Divine Ice Sword Combination Style..."

However, he couldn't. In fact, he couldn't move at all. It felt like his whole body was encased in a layer of ice.

"...Final Stance..."

He trembled in fear. He couldn't help himself. In his life, he went through quite a few helpless situations, but in the end, he always pushed through somehow. But now, he could only see death.

His deceased ancestor warned him never to provoke Yuna, but he simply dismissed his words. In his mind, no one would forever be invincible. Apparently, his thoughts were wrong.

"... One Slash to End All Life..."

Yuna slashed down her sword.

"...Divine Severance]"

Everyone watching felt their bodies getting cut into thousand pieces, and it would take them quite a bit of time to realize that Yuna had only directed her attack at a single person.

The ice blade passed through the demon cultivator, instantly cutting him in two halves while both of the sides turned into ice statues.

However, neither of the parts moved from their position, and after the situation calmed down, the case was investigated, revealing that the reason they didn't fall was because of how cold the ice statues he turned into were.

Not only was space around the statues frozen, even time could not move around them, meaning that even divine sense could not get close to them. In the future, the two parts of the demon cultivator's body would be seen as a holy sight for cultivators as they could witness the aftereffects of this realm's uncontested, strongest attack.

As for Yuna, after she finished her attack, she started crumbling away, turning into snow.

'Ha~ Such a good life. I am statisfied~'
