Junior sister, I really need to control you

With a flick of his longsword, each sword light behind him split in two. The split sword lights did not become dim, but instead became brighter, and each one became even more powerful!

Two hundred and fifty-six sword lights!

Li Yinsheng: ...

Chapter 83 Five Hundred and Twelve Sword Lights!

Within the magical grotto.

Li Yinsheng was submerged by the long river of sword light.

His and his junior sister's reflections flew from the Jade Platform to a height of a thousand feet in the sky, and then chased each other all the way back to the ground. The long river of countless sword lights relentlessly pursued him.

No matter how strong a body cultivator's physique is, it cannot withstand such erosion.

Moreover, after the Yin-Yang Dividing Light Sword was upgraded to 256 sword lights, a number Li Yinsheng had never heard of before, its power had greatly increased, and it was no less powerful than the killing spells on the third floor of the Scripture Pavilion in the temple.

Engulfed by such a long river of sword light, if Li Yinsheng relied solely on his physical strength to withstand it, he estimated that he would eventually be worn down to death.

Of course, if it weren't within a grotto-heaven where magical power is practically limitless, this sword light wouldn't be able to flow endlessly.

The Two Elements Dividing Light Sword released 128 sword lights in one go, which was already a considerable drain on a True Person, let alone 256 sword lights wave after wave.

Even if he were to encounter an opponent with such unbelievably profound magical power, he would not foolishly try to fight them head-on.

Body cultivators are not revered simply because of their high defense and high health.

For him, enduring such an attack to rush to his junior sister's mirror image and unleash a punch was not a difficult task.

But he couldn't do that inside this magical cave.

As long as any means other than the Yin-Yang Dividing Light Sword are used, the warning from the cave will arrive.

Besides, his junior sister's aura was exactly the same as his; who isn't a cultivator?

While fighting his junior sister with the Yin-Yang Dividing Light Sword, he also tried various other methods.

For example, one could directly separate their soul from their body, thus increasing their speed and the power of their sword techniques.

Then the junior sister's mirror image's soul also left her body.

Then Li Yinsheng discovered that although the soul could recover instantly from injury in the magic cave, the injury to the soul was much more painful than the injury to the physical body!

He also tried to directly retreat when facing his junior sister's sword techniques, instead of foolishly exchanging blows with her magic, and instead moved around looking for openings.

But this is meaningless.

His junior sister's mirror image had the same cultivation level, spiritual sense, and physique as him. He himself did not know any advanced escape techniques, so how could he compete with these sword lights in speed?

Moreover, he estimated that even if there was a way to avoid its sharp edge, after a while, Dongtian would probably warn him that this was slacking off.

So he could only endure the endless sword light, taking the beatings while trying to decipher his junior sister's 256 sword lights.

Although the manual for the Yin-Yang Dividing Light Sword never mentioned that the number of sword lights could be increased beyond 128, the extra sword lights that my junior sister had were clearly not added out of thin air. They were actually an extension of the Yin-Yang Dividing Light Sword to a higher level!

As someone who experienced these sword lights, Li Yinsheng was able to discern what had been added to them after careful observation.

He then began to imitate these extra elements in his own feelings.

As he expected, with his deliberate imitation, the number of sword lights of the Yin-Yang Dividing Light Sword, which should have been completed at 128 sword lights, began to increase again!

129, 130, 131...

One hundred and ninety-six, one hundred and ninety-seven...

Two hundred and fifty-four, two hundred and fifty-five...

Two hundred and fifty-six!

Li Yinsheng hovered high in the sky, roaring to the heavens. Behind him, two hundred and fifty-six sword lights soared into the sky, each sixty or seventy feet long. From a distance, it looked like a bright mountain peak suspended in the sky!

Originating from this mountain peak, a river of sword light, no less impressive than the mirror image of her junior sister, poured down from the summit, standing shoulder to shoulder with her!

Two bright sword-shaped mountain peaks faced each other in the night sky, their sword lights eroding each other, as if two dazzling star rivers had suddenly appeared in the sky, even dimming the moonlight.

"Two hundred and fifty-six sword lights, such a sword technique, who will dare to say I am not a sword cultivator in the future! Junior sister, I really have to thank you for your guidance this time!"

Even though he knew the mirror image wouldn't respond, Li Yinsheng couldn't help but speak.

Over the years, he's been so busy getting beaten up and studying sword techniques in the cave that he's almost driven crazy with boredom.

Having endured so much hardship to finally master these unprecedented 256 sword beams, I must go back and show them off to my master!

A smile of relief appeared on Li Yinsheng's lips.

Immediately, his divine sense detected that his junior sister's image seemed to have changed her sword technique again.

The 256 sword lights split in two once again, each sword light now nearly a hundred feet long. The sword light mountain behind the junior sister was a little shorter, but it still stretched into a mountain range.

The sword-like river cascading down from the mountaintop transforms into the winding and mighty Yangtze River.

Five hundred and twelve sword lights!

Seeing the overwhelming torrent of swords rushing towards him, Li Yinsheng was first stunned, then smiled with relief.

……

At the summit of Bamboo Forest Peak, Li Yinsheng, who was sitting cross-legged, slowly opened his eyes.

"It feels like a lifetime ago..." he murmured to himself.

He had experienced this feeling many times during his secluded cultivation in the cave, but never as intensely as it was now.

It was probably because he had only been in seclusion for cultivation. As long as he calmed his mind and focused his spirit, although the time was still long, there would be no other things to distract him.

But this time, he had truly fought his junior sister's mirror image in the cave for so many years.

At this moment, his Yin-Yang Dividing Light Sword had reached a level of 512 sword lights that was unprecedented and unlikely to be surpassed in the future.

He also confirmed something.

Sword cultivators are indeed terrifying in combat.

If cultivation levels are equal, the Yin-Yang Dividing Light Sword with its 512 sword beams is indeed enough to annihilate fellow body cultivators.

However, the cave not only allows one to instantly restore magical power and injuries, but also to revive.

He had lost count of how many times he had died before he finally mastered these 512 sword lights.

He didn't feel much about dying in the cave, after all, he had died before, and he already had the feelings he should have when he died the first time.

What troubled him was that after 512 sword lights, his junior sister's image stopped receiving new sword lights.

He did not witness the spectacular sight of 1,024 sword lights.

To be fair, he was still a little disappointed.

It's unclear whether this is because the Two Elements Dividing Light Sword has reached its limit, or whether five hundred and twelve sword lights are already the limit for his current cultivation level.

After all, if his magical power in the cave could not be restored in an instant, he really wouldn't be able to unleash the 512 sword lights many times.

This is really too much of a drain on resources.

After mastering the Yin-Yang Dividing Light Sword, he practiced the Mysterious Fiend Sword.

However, he spent too much time practicing the Two Elements Dividing Light Sword. Although he reached the level of 512 sword lights, he only managed to cultivate the Mysterious Fiend Sword to the point where he could utilize 256 sword lights.

In fact, the Ferocious Sword can only control 128 sword beams.

Li Yinsheng died countless times at the hands of his junior sister before he finally learned how to use 256 sword lights to unleash a higher level of the Xuan Sha Xiong Xiang Sword.

He couldn't help but marvel at how the Mysterious Fiend Sword was truly a top-tier killing technique.

Based on his personal experience, the Xuan Sha Xiong Xiang Sword, with its 256 sword lights, was more powerful than the Liang Yi Fen Guang Sword, with its 512 sword lights.

However, the consumption will also need to be increased.

Even if he had enough time left to learn an even higher level of the Ferocious Sword Technique, he might not be able to use it.

In his spare time, he devoted himself to the insect-controlling techniques of Chongyun.

The art of controlling insects is not difficult in itself, and it can be considered to have been mastered to a high degree.

In addition, over the past hundred years, the Go Soul has deduced most of the knowledge from those hundreds of books on formations.

Although he hadn't learned any new formations, Li Yinsheng felt that he could be considered a formation master based on theoretical knowledge alone.

After nearly a century of nurturing, the Azure Sword is probably more than ten times stronger than when it was first forged.

The wood element energy within it was several times stronger and more refined, but in Li Yinsheng's perception, the wood element energy seemed to be splitting into two.

To be precise, it seems to be about separating Yin and Yang.

Half of its energy is of the wood element and leans towards yang, resembling a towering ancient tree.

The other half of the wood element is yin in nature, resembling flowers, grasses, and vines.

Although Li Yinsheng didn't have much knowledge of the Five Elements, he wasn't completely ignorant either, especially since he had previously discussed the Five Elements theory with Langya.

This must be because the wood element energy within the Azure Sword has grown to a certain level and begun to differentiate into yin and yang on its own.

The yang element is Jia wood, and the yin element is Yi wood. The two embracing yin and carrying yang is not necessarily a bad thing.

If this step can be accomplished, the Azure Sword will likely be elevated to a higher level as a result.

However, this step seems not so easy. The Azure Sword's foundation should be sufficient now, but it still lacks a certain opportunity to truly evolve Yin and Yang.

Just as Li Yinsheng was immersed in the Azure Sword, a face he knew so well that it was etched into his bones and soul entered his consciousness.

He instinctively shivered.

Mu Xiaoyu pushed open the door and walked in, her face beaming with joy: "Senior brother! Can we go home tomorrow?"

"Yes...yes." Li Yinsheng nodded with a somewhat stiff smile.

"Yay!" Mu Xiaoyu cheered, then asked with some confusion, "Senior brother, your complexion doesn't seem quite right."

"Really?" Li Yinsheng asked with a stiff face.

"Yes!" Mu Xiaoyu nodded, took two steps forward, and asked with concern, "Senior brother, did you not get enough rest?"

As Mu Xiaoyu approached, Li Yinsheng subconsciously leaned back slightly.

Then he shook his head and said, "Don't worry, junior sister, I'm fine."

It's just that you've been chopping and killing people for decades.
