Junior sister, I really need to control you.

At dawn, Li Yinsheng pushed open the door of the Xuanzhen Temple and entered the Sutra Repository.

My junior sister's screams were extremely pitiful last night.

Li Yinsheng never expected that the method left by that senior immortal, which enhanced the effects of the Pure Profound Divine Light in cleansing the meridians and marrow, would be so effective.

With just a few attempts, he increased the efficiency of the Qingxuan Divine Light's cleansing and marrow-refining technique several times over.

Of course, the pain also increases by the same amount.

Therefore, the junior sister's screams were extremely tragic, and she resolutely refused to continue the marrow cleansing.

After all, they said that the pain would gradually lessen after the bone marrow cleansing treatment, but this time it hurt even more than the first time.

Li Yinsheng could only lament that technological progress is indeed not something everyone can accept.

In order to entice her to persevere, Li Yinsheng had no choice but to agree that if she completed this marrow cleansing and bone marrow treatment, she could get up half an hour later that morning.

Li Yinsheng figured that if he could seduce her a few more times in this way, getting her through the most painful first few sessions of the new version of the "Marrow Cleansing" technique, he could then use the same method again.

He patiently persuaded Mu Shimei that the most painful stage was truly over, and that it would be a huge loss to give up now, so she should persevere.

However, the process of cleansing the tendons and marrow requires perseverance and cannot be rushed.

While pondering his plan to cleanse his junior sister's marrow and tendons daily, Li Yinsheng went up to the second floor of the Sutra Repository.

The most advanced cultivation techniques and spells in the temple are all on the third floor, but the cultivation technique recommended by my martial uncle is on the second floor.

The spells stored on the second floor are mostly very practical and have their merits, but they are undoubtedly a level below those on the third floor.

If it weren't for his uncle's recommendation, he would have definitely just found a relatively simple spell on the third floor for his junior sister to practice.

He walked to the bookshelf in the corner and pulled out a secret manual with old, worn pages.

"The Two Elements Dividing Light Sword..." Li Yinsheng nodded, "This is the one."

After looking through it for a while, Li Yinsheng nodded slightly.

This spell is indeed quite good. Although it is a sword cultivation spell, it can be applied to most cultivation methods and does not require the main cultivation method to be a sword cultivation method.

Its cultivation method and effects are simple and unadorned. Its way of fighting enemies is to swing the sword light and slash straight at them.

The reason it is named "Splitting Light" is because as this spell becomes more and more proficient, the amount of sword light that can be unleashed with a single swing will also increase.

The concept of "two elements" refers to the idea that when the number of sword lights is doubled compared to the previous one, the power of a single sword light will actually increase.

For example, when this spell is first mastered, it can only emit a single sword light, and the power of this sword light is somewhat weaker than that of the melee attack.

However, once one cultivates to the point where one can unleash two sword lights at once, the power of either of these two sword lights is almost the same as that of the White Blade Technique. When both are unleashed simultaneously, this is something that the White Blade Technique cannot achieve.

When one becomes more skilled and can unleash four sword beams with a single strike, even a single sword beam is superior to melee combat, let alone four sword beams unleashed simultaneously.

Moreover, according to my uncle and the records in the manual, it is not difficult to cultivate to the level of four sword lights. Even people with ordinary talent can achieve it by focusing on training for three to five years.

However, if you want to increase the power of your sword light in the future, you will have to train until you can release eight sword lights at once, which will take many years of hard training.

The next time it will be sixteen sword lights to achieve a qualitative change, then thirty-two, sixty-four...

Therefore, most people who practice this sword technique will not engage in a life-or-death struggle with it, because although the improvement is greater as you progress, the difficulty also increases exponentially.

Moreover, it has a significant drawback—

Compared to the path of "one sword to break all laws" that most sword cultivators pursue, which has extremely high explosive power, the Two Elements Dividing Light Sword does the opposite.

The power of the Two Elements Dividing Light Sword is not strong; its strength lies in its continuous attacks, but it lacks a decisive means to win in one strike.

I've never heard of a swordsman fighting someone using gua sha (scraping therapy).

Most sword cultivators wished they could decide the outcome of a battle with a single, all-out sword strike.

Although the Yin-Yang Dividing Light Sword is not bad, its characteristics mean that most sword cultivators will not use it as their main spell.

They usually just learn it casually, to supplement their conventional methods.

However, her martial aunt recommended this sword technique to Li Yinsheng because she had a way to make up for the lack of a killing move in the Yin-Yang Dividing Light Sword.

If this weakness is addressed, the Two Elements Dividing Light Sword will be a sword technique with almost no flaws, and it can be directly placed on the third floor of the Scripture Pavilion.

My uncle's method for making up for his shortcomings is very simple.

In her early years, while she was training in the field, she accidentally obtained a fragment of a superior sword technique.

Afterwards, she spent a great deal of effort developing an extremely powerful killing sword technique based on that incomplete manual.

That sword technique was her trump card for a long time; once unleashed, it could even instantly kill enemies with higher cultivation levels than her.

The only problem is that this sword technique requires a large amount of sword light as a foundation to be used.

The more sword light there is, the greater the power of this killing sword technique.

Therefore, a sword technique that can differentiate sword light is very important.

The Two Elements Dividing Light Sword is the best of these sword techniques.

However, writing books is extremely energy-consuming. Back then, she was young and impetuous, busy with cultivation and travel. Even when she had some free time, she preferred to challenge her friends to duels.

Therefore, he did not compile his self-created killing sword technique into a book and store it in the library.

But since her cultivation was completely destroyed, she has lived a secluded life, and with nothing to do, she has long since summarized all her knowledge.

Once my junior sister has mastered the Yin-Yang Dividing Light Sword to the point where it has eight sword lights, she can begin to learn her killing sword technique.

Although if one only has the foundation of eight sword lights, one can only learn the very basics of that sword technique.

But the senior master confidently assured that it would be more than enough for his junior sister to stand out among most cultivators of the same level.

We sword cultivators may not have any other advantages, but we are strong! We can fight! We are extremely strong!

I'm not afraid of encountering body cultivators!

Li Yinsheng picked up the Yin-Yang Dividing Light Sword, stood in front of the bookshelf, and began to browse through the books.

Although it was mainly for his junior sister to cultivate, he himself hadn't practiced any good spells.

Previously, I focused all my energy on improving my cultivation level, and only practiced a few simple and practical spells. Now that my cultivation level has improved, everything has happened too fast, and I haven't had time to learn better spells.

Since his martial uncle highly praised the Yin-Yang Dividing Light Sword, he naturally wanted to learn it as well.

Although as a body cultivator, he is not afraid of sword cultivators in terms of combat strength, sword cultivators are just cool!

Li Yinsheng was self-aware; his comprehension was neither good nor bad, just average.

But now that he is a real person, not only is his spell power greatly increased, but learning spells is also much easier than before.

After examining the Yin-Yang Dividing Light Sword without stopping, Li Yinsheng raised his hand and pointed, and a sword light appeared beside him.

Although the Yin-Yang Dividing Light Sword is a sword technique, with his current cultivation level, it is not difficult for him to use his fingers instead of a sword.

A moment later, the sword light split into two.

After a while, the two sword lights turned into three.

About half an hour later, the fourth sword light also emerged.

Li Yinsheng nodded slightly and dissipated the sword light.

What would normally take a cultivator three to five years to master—four sword beams—was accomplished in him in just half an hour.

However, correspondingly, the current sword light is not very meaningful to him.

In terms of sheer power, if we're only talking about the four sword beams, they're not even as powerful as the two punches he throws casually.

"Hmm, judging by the time, Junior Sister should be up and cultivating now." Li Yinsheng put away the manual for the Yin-Yang Dividing Light Sword and muttered to himself.

"Junior sister has made good progress recently. Today, we can try adding another ten jin to the weight of the Qi Refining Lock."

"Then let her practice for two hours to warm up."

"After the warm-up, I can teach her the Yin-Yang Dividing Light Sword."

"The Two Elements Dividing Light Sword is quite easy to learn. If she works hard enough, she might be able to master the first sword light of the Two Elements Dividing Light Sword today."

"Hmm, another fulfilling day."
