Junior sister, I really need to control you.

In front of the main hall of Xuanzhen Temple.

Mu Xiaoyu gripped the White Rainbow Sword, performed a sword incantation, and with focused concentration, thrust out a sword, sending out four streaks of sword light in an instant.

A hint of joy unconsciously appeared on her face.

Three days ago, she mastered the third sword light, but the fourth one was significantly more difficult.

Although she never found a chance to slack off under her senior brother's supervision, she still practiced hard until today and finally mastered the fourth sword light.

But then she felt her hands go empty.

The White Rainbow Sword transformed into a thin stream of light and flew towards Li Yinsheng, who then swallowed it whole.

Then a glint flashed in Li Yinsheng's eyes.

"Senior brother?"

Mu Xiaoyu was initially puzzled after her White Rainbow Sword was taken away, but then she felt a glimmer of hope.

Previously, she would always finish practicing her sword skills for the day before her senior brother would put the White Rainbow Sword back into his body to nurture it.

But it should still be about two more hours before we finish practicing swordsmanship.

Could it be that her senior brother is planning to give her a break so she can practice for two fewer hours?

Li Yinsheng had no idea what Junior Sister Mu was thinking. He was just sensing the slight changes in the White Rainbow Sword within his body and sighed inwardly.

He just retrieved the White Rainbow Sword because his junior sister had mastered the fourth sword light, triggering a reward that he needed to enter the cave to claim the two years of cultivation.

The nurturing of magical artifacts by a true person can be done at any time, including during cultivation.

So before entering the cave, he also absorbed the White Rainbow Sword into his body and nurtured it within the cave.

Although two years of cultivation were of little use to his current level, they only slightly increased his magical power and blood energy.

However, the time he spent nurturing the White Rainbow Sword until today, before receiving the reward, was less than ten days. He felt that two years should be of considerable help to the White Rainbow Sword.

Then he realized he was overthinking it.

The nurturing over the past two years has not been without its benefits for the White Rainbow Sword, but the changes have been minimal, except that its spirituality has become slightly more active.

Ultimately, it is probably because its main body was severely damaged.

The spirituality of the White Rainbow Sword is still only two or three tenths of what it was at its peak. As Junior Sister's Yin-Yang Dividing Light Sword becomes more and more proficient, the effect of her guidance will probably become worse and worse.

Even if the White Rainbow Sword is repaired one day, its ability to guide junior sister in cultivating the Two Elements Dividing Light Sword will never surpass the highest level of her master back then.

But at least in terms of efficiency and potential, it will definitely be much higher than it is now.

Just as Li Yinsheng was sighing inwardly, Mu Xiaoyu spoke up.

"Senior brother, can we reduce our cultivation time by two hours today?" she asked expectantly.

Li Yinsheng asked, "Hmm? What makes you say that, Junior Sister?"

"Senior brother, you've already put the White Rainbow Sword away," Mu Xiaoyu said matter-of-factly. "Didn't you only put the sword away when it was time to rest before?"

Li Yinsheng was both amused and exasperated, realizing that this was the reason.

"If Junior Sister doesn't want to practice swordsmanship today, that's fine too," he nodded.

Mu Xiaoyu's face lit up with joy.

"Then let's use the rest of the time for lecturing and teaching," Li Yinsheng said. "We'll usually lecture for half an hour, and then write two exam papers afterward."

He paused, then added, "Since we're going to lecture for two and a half hours straight this time, how about we write ten exam papers? What do you think, junior sister?"

"No, no, no! Senior brother, I want to practice swordsmanship! I want to practice swordsmanship!" Mu Xiaoyu said hurriedly, her face full of fear.

"Junior sister, didn't you not want to practice swordsmanship?" Li Yinsheng asked, "Besides, the White Rainbow Sword can still stab you."

"Senior brother, I was just joking. Actually, what I like most is practicing swordsmanship!" Mu Xiaoyu said.

Compared to the sharp, stabbing White Rainbow Sword, studying scriptures and writing exam papers are far more terrifying.

"Junior sister, are you sincere?" Li Yinsheng asked.

"I really mean it!" Mu Xiaoyu nodded.

Li Yinsheng nodded, and the White Rainbow Sword flew towards Mu Xiaoyu, landing back in her hand.

Feeling relieved that she had escaped a calamity... having narrowly escaped a near-death experience, Mu Xiaoyu breathed a sigh of relief and prepared to continue practicing her swordsmanship.

Li Yinsheng stood up and said, "Wait, junior sister, don't you find practicing swordsmanship like this a little boring?"

"It's a bit boring... no, it's extremely boring!" Mu Xiaoyu thought for a moment and nodded repeatedly.

What if her senior brother takes pity on her and lets her practice less?

After a pause, not wanting her senior brother to make her bored by doing exercises, she added, "But studying scriptures and writing scrolls is even more boring!"

Li Yinsheng smiled.

"Since you find practicing swordsmanship alone boring, junior sister, I'll be your sparring partner. Having someone with you will make it less boring, won't it?"

As Li Yinsheng walked toward Mu Xiaoyu, he stretched as if to warm up.

Mu Xiaoyu's expression of agreement instantly turned into horror.

"No need, no need!" she hurriedly backed away. "Senior brother, I'm not bored anymore! Sword practice is so much fun!"

"But you still need sparring partners," Li Yinsheng said. "Sword techniques are for combat; how can they be effective without real fighting?"

Although he himself didn't have much practical combat experience, he had accumulated some combat experience from occasionally sparring with other cultivators or encountering monsters while searching for medicinal herbs.

And my junior sister...

He planned to send his junior sister to the Trial of the Blades competition to give it a shot.

If we can really get a spot in the Sword Washing Mountain, it should greatly improve the progress of the Two Elements Dividing Light Sword.

To participate in the "Test of Skills" competition, practical experience is essential.

At this point, the junior sister already had four sword lights, and could begin practical training.

"Senior brother, you'll go easy on me, won't you?" Mu Xiaoyu asked with a mournful face.

Although she hadn't personally witnessed her senior brothers fighting, she had seen firsthand the miserable state of those people at Huanghe Temple.

"Of course, it's just a friendly spar. Do you think I would take advantage of you, Junior Sister?" Li Yinsheng shook his head and chuckled.

Mu Xiaoyu breathed a sigh of relief.

Then she saw Li Yinsheng wave his hand with a smile, and twenty or thirty sword lights appeared around him.

Mu Xiaoyu: ……

……

A month and a half later.

In front of the main hall, Mu Xiaoyu and Li Yinsheng stood facing each other.

She was no longer using the White Rainbow Sword, but the Cold Leaf Sword that Li Yinsheng had given her before.

A thick layer of azure light emanated from the Cold Leaf Sword. As she unleashed her sword technique, the azure light spread from the sword, transforming into ten azure sword lights that shot towards Li Yinsheng.

Li Yinsheng, who was being pointed at by ten sword lights, pointed his finger and only a faint blue sword light appeared in front of him.

His sword light was much lighter in color than Mu Xiaoyu's.

Or rather, it needs to be much "clearer".

This is also one of the characteristics of the power of the Qingxuan True Scripture. As the level increases, the quality of the power becomes higher and higher, and it looks more and more transparent and clear.

With a startled cry from Mu Xiaoyu, her attack, composed of ten sword lights, was easily bypassed by the pale blue sword light that found an opening.

The sword light struck her, but caused no harm. It merely transformed into a gentle force that sent her flying backward, landing on her bottom.

"Senior brother cheated!" Mu Xiaoyu sat on the ground, looking aggrieved.

Li Yinsheng stepped forward and pulled her up: "Oh? How did I cheat?"

"Um..." Mu Xiaoyu was speechless for a moment, and could only puff out her cheeks to express her dissatisfaction.

That wretched senior brother!

I've been sparring with her every day this month, but I've never let her win!

"Alright, alright, you did a good job today. Here, have a candied hawthorn."

Li Yinsheng handed a candied hawthorn to Mu Xiaoyu.

Although most of the snacks were in Mu Xiaoyu's own Qiankun bag, Li Yinsheng also kept some for himself.

Of course, most of it ended up in Mu Xiaoyu's stomach.

Mu Xiaoyu immediately took it, and the anger on her face instantly dissipated.

After Mu Xiaoyu finished eating the candied hawthorn, Li Yinsheng did not make her practice swordsmanship immediately.

Instead, he immediately began practicing his skills.

She currently only has the second level of the Qingxuan True Scripture, and her magical power is still very weak. After the battle just now, with ten sword lights being unleashed at the end, her magical power was depleted. She needs to practice her skills to recover for a while before she can continue practicing her swordsmanship.

Li Yinsheng had already received four years of cultivation as a reward from the eight sword lights, and he also took the opportunity to nurture the White Rainbow Sword for another four years.

Unfortunately, even four more years of nurturing wouldn't significantly enhance the sword's spiritual essence.

Moreover, as the junior sister's sword light cultivation increased, the guidance of the White Rainbow Sword noticeably slowed down.

It only takes a little over a day of practice to go from two sword lights to three sword lights.

It only takes three days to go from three sword lights to four sword lights.

However, a full month and a half has passed since the initial four sword lights were replaced by the current ten.

To be precise, it only took about twenty days to go from four sword lights to eight sword lights. The remaining twenty-odd days were spent on the ninth and tenth sword lights.

Moreover, because he also practices the Yin-Yang Dividing Light Sword, he has realized that although the power of the sword light increases each time the number of sword lights doubles, it becomes more difficult to increase the number of sword lights after that.

At this rate, it will probably take another two months or so of training to reach sixteen sword lights.

After the sixteen sword lights are completed, it's possible that only one or two more sword lights can be added per month.

Although this speed is already very fast compared to the normal credit lightsaber training, it only takes a little over a year to train to thirty-two sword lights.

After all, practicing swordsmanship with a true master's natal magic weapon every day is a privilege that even the true master's successor would never receive.

Even if this natal magic weapon is severely damaged.

But what happens next?

After the thirty-two sword lights, the difficulty will increase further.

Moreover, by then, the White Rainbow Sword, with only 20-30% of its spiritual power remaining, will offer significantly less benefit.

It might take more than a month to grow one sword beam.

Based on this calculation, if the three-year period is completed, it is likely that even the goal of sixty-four sword lights will not be achieved, let alone the final level of one hundred and twenty-eight sword lights.

Just as Li Yinsheng was frowning in thought, his consciousness stirred, and he looked up at the corner of the main hall.

Uncle Jiang, dressed in white, walked over from under the corridor.

Li Yinsheng smoothed his eyebrows and walked towards his martial uncle with a smile.

After learning that he was the real person, the martial uncle seemed to relax a bit and stopped being so reclusive.

For the past month or so, she has often come to the main hall to visit, either to chat with her junior apprentice or to watch Mu Xiaoyu practice swordsmanship or spar with him.

"Uncle-Master," Li Yinsheng said, bowing.

Uncle-Master Jiang smiled and shook his head: "Let's skip these formalities from now on. True cultivators usually address each other as fellow Daoists."

"Although we are both in the Xuanzhen Temple, we are of different generations and are still uncle and nephew, but there is no need for these formalities."

Li Yinsheng shook his head and smiled, "I've gotten used to it over the years. I'll change it slowly in the future."

Uncle Jiang didn't press the matter and changed the subject.

"How's your junior sister's progress with the Light Splitting Sword technique?"

Li Yinsheng looked at Mu Xiaoyu. She had been practicing for a while and her magical power had recovered considerably.

"Junior sister, it's time to practice your sword."

As Li Yinsheng spoke, the White Rainbow Sword flew from his hand into Mu Xiaoyu's.

"I know, Senior Brother!" She took the sword, only to realize that Martial Uncle Jiang was also there. She quickly turned the sword downwards, bowed, and said, "Martial Uncle is here too. Greetings, Martial Uncle!"

Uncle Jiang nodded slightly in return, his gaze lingering for a moment on Mu Xiaoyu's hand and the White Rainbow Sword.

Afterwards, Mu Xiaoyu began practicing the Split Light Sword.

"What does Uncle-Master think?" Li Yinsheng asked.

"Although she is still very inexperienced, given her natural talent, it is already quite good that she has reached this level. At least it proves that she has not been lazy." Uncle Jiang nodded slightly.

"This child is indeed quite diligent," Li Yinsheng nodded and smiled. "Compared to me back then, she is even more diligent."

In my opinion, they are evenly matched, neck and neck.

Uncle Jiang stared at Mu Xiaoyu's figure as she practiced her sword, his gaze somewhat lost in thought, as if he were thinking about something.

"The only difference is that you rely entirely on yourself; there's no one constantly pushing you from behind."

Before Li Yinsheng could say anything, she spoke again, her tone becoming more serious: "However, I think her Yin-Yang Dividing Light Sword seems to be a bit slower than before."

"After all, the Splitting Light Sword becomes increasingly difficult as you progress," Li Yinsheng said.

"That's true, but that's not the only reason," said Uncle Jiang. "She herself doesn't have a deep understanding of using the Yin-Yang Dividing Light Sword, so she'll be slower in the endurance."

"My junior sister and I spar a lot," Li Yinsheng said.

Uncle Jiang shook his head: "It's not a friendly spar, she needs a real fight... Well, calling it a real fight might be a bit of an exaggeration, but it has to be a real battle, not just a friendly spar."

"When she has real combat experience with the Yin-Yang Dividing Light Sword, and realizes that she needs to rely on the magic sword and sword techniques in her hand to truly fight to the death with her opponent."

"Only then will she truly understand that the Yin-Yang Dividing Light Sword is not just a sword technique she is learning, but is also closely related to her life."

"With this understanding and knowledge, she will be able to improve both the speed at which she cultivates the Yin-Yang Dividing Light Sword and the power she wields it."

Li Yinsheng seemed to understand, then said, "I think I understand, but I don't think I've experienced it myself."

"After all, you are one of the very few cultivators who never treated magic as a game from the very beginning when they first learned it, so you can be said to have skipped this step by nature," said Uncle Jiang.

She paused, then added, "Actually, I'm the same way."

Li Yinsheng nodded, pondered for a moment, and then asked, "Then, Uncle-Master, do you think it would be effective if I found a weaker demon and had my junior sister fight it?"

With her current combat power, finding a demon of similar strength would be incredibly easy for her.

Powerful monsters are rare, but weak monsters are plentiful!

"Yes, that's fine," Uncle Jiang affirmed. "And you don't need to go far."

"The area around Xuanzhen Peak hasn't been cleared for many years. If you use your divine sense to explore the surrounding mountains carefully, it won't be difficult to find two demons."

Li Yinsheng nodded.

It's unlikely that there are any demons around a proper Taoist temple, not even the lowest level ones. After all, a Taoist temple has hundreds of disciples, and if someone occasionally goes to the nearby mountains for a stroll to relax, they will have already cleared away any demons.

However, Xuanzhen Temple is an exception.

After Li Yinsheng became a True Person, he also used his divine sense to scan Xuanzhen Peak.

Although there were no demons on Xuanzhen Peak, he did sense a demonic aura emanating from several surrounding mountains when he explored the peak.

However, those demonic auras were too weak, mostly only slightly stronger than his junior sister's, and they were hiding in the mountains, so they had no chance to harm people. Therefore, Li Yinsheng had always been too lazy to care about them.

Ultimately, demons are not demon cultivators; the two are worlds apart.

Ordinary demons, if they do not cultivate to a certain level, have a lifespan no different from that of ordinary wild beasts. They cannot live for more than ten years, and some may not even live for more than a few years. It is normal for them to live and die on their own.

He has so many things to do, how could he waste time with a few insignificant monsters?

But now...

Since it concerns his junior sister's cultivation, he really had to take her to visit the little cuties on the surrounding mountains.
