Junior sister, I really need to control you.

Mu Xiaoyu gripped the White Rainbow Sword and walked back to where she had practiced swordsmanship before. She was about to try practicing, but then she became a little worried and looked at Li Yinsheng.

"Senior brother, this sword is covered in cracks, won't it break?"

Li Yinsheng calmly replied, "Junior sister, don't worry. Magic treasures are much tougher and sharper than magic weapons, even in their current state."

Mu Xiaoyu breathed a sigh of relief, stood still, held her sword, and closed her eyes to regulate her breathing.

Normally, she wouldn't be this proactive.

But the White Rainbow Sword was too beautiful, and it was also exceptionally easy to hold. Even though Mu Xiaoyu was quite tired, she couldn't wait to use it.

After standing still and adjusting her breathing, she circulated her magic power and unleashed the Yin-Yang Dividing Light Sword, based on the feeling she had practiced many times before.

But in the instant she unleashed the attack, she felt a cold sensation flow into her body from the hilt of the sword.

As she channeled her magic to unleash the Splitting Light Sword, the icy sensation spread through her meridians, sharpening her at over a dozen acupoints and meridians.

The moment the stinging sensation appeared, the way she circulated her magic subtly changed. When the light from the Yin-Yang Dividing Light Sword was unleashed, it was noticeably more solid and brighter than before.

"Ugh!"

Mu Xiaoyu didn't have time to pay attention to any changes in the sword light she had unleashed. She clutched her wrist and looked at Li Yinsheng with a wronged expression.

"Senior brother, this sword...it's stabbing me!"

Li Yinsheng remained expressionless—his martial uncle had told him this would happen before.

"Junior sister, don't worry. This is the spirit within the White Rainbow Sword guiding you in practicing the Yin-Yang Dividing Light Sword with its sword intent."

Li Yinsheng explained, "This sword intent will not harm your body; it will only stimulate your acupoints and meridians with the sensation of pain."

"This will subtly change the way you circulate your magic, making you more suited to wielding the Split Light Sword. You must remember this change and try to imitate and learn it."

Mu Xiaoyu was dumbfounded, on the verge of tears.

"So this is how you're instructed! How is this any different from a teacher hitting your hands with a ruler!"

No, there is still a difference.

The teacher would only hit her hand with a ruler when she didn't do her homework or was being naughty.

And this sword, she would stab her every time she cast a spell.

Wouldn't that mean that when she was reading and writing, the teacher would hit her hand with a stick every time she read a sentence or wrote a line?

That's terrifying!

Looking at the white rainbow sword in her hand, her eyes no longer held any of the previous fondness, only pure terror.

"Senior brother, I don't want this sword anymore, it hurts too much. Let's return it to our uncle!" Mu Xiaoyu said quickly.

"What? Does this sword intent hurt a lot?" Li Yinsheng was taken aback.

He had asked his martial uncle, and he had learned that the sword intent stimulating acupoints and meridians was only to guide the flow of magical power, not to inflict torture, so it shouldn't be very painful.

Moreover, he had tried it himself beforehand, and it really didn't hurt much; it was far less painful than the burning pain of the Blood Refining Pit.

"It hurts a lot!" Mu Xiaoyu nodded.

"Then... how does it compare to the Cleansing and Marrow-Cleansing Divine Light?" Li Yinsheng asked.

Mu Xiaoyu shook her head: "That still can't compare. It's probably only one-tenth of the marrow cleansing... no, one-twentieth, um, not even that..."

After careful consideration, she gave a definite answer: "Maybe, about the same, roughly, about one-thirtieth of the pain."

Li Yinsheng nodded knowingly.

That's right, that's about the same level of pain as him.

"Junior Sister can persevere even with the Marrow Cleansing Technique, let alone the mere guidance of the White Rainbow Sword's spiritual essence?" Li Yinsheng asked.

Mu Xiaoyu puffed out her cheeks.

Although it's nowhere near as painful as a bone marrow cleansing ritual, who would like to be hurt for no reason?

"Senior brother, although the bone marrow cleansing is very painful, you only have to endure it for a short while each day, and you said that it will become less and less painful over time."

"If I were to practice the Yin-Yang Dividing Light Sword with this sword, wouldn't it hurt for as long as I practiced? And it would hurt all the time!" Mu Xiaoyu said with a face full of rejection.

"Why does it keep hurting so much?" Li Yinsheng shook his head and said, "Junior sister, think about it. This stinging pain is just to make your magic power more accurate when it is circulating."

"If you can control your magic more and more accurately, the stimulation it needs to give you will become less and less."

"So as long as you become more and more proficient with the Yin-Yang Dividing Light Sword, it will become less and less painful. This is similar to the Meridian Cleansing and Marrow Strengthening, and besides, it doesn't hurt much to begin with."

Mu Xiaoyu seemed to be deep in thought.

"Oh, I see..." She was still a little reluctant. "But it's okay to practice a little slower, I think practicing normally is fine too."

Who says it's okay to be slow? Do you know you only have three years?! Li Yinsheng thought to himself.

"I see. Then it's alright if Junior Sister doesn't want to use the White Rainbow Sword..." Li Yinsheng said leisurely.

Mu Xiaoyu's eyes lit up, and she was about to run over to return the White Rainbow Sword to Li Yinsheng.

"I was thinking that if my junior sister was willing to practice with the White Rainbow Sword, it would enhance your skills and allow you to practice the Two Elements Dividing Light Sword for half an hour less each day," Li Yinsheng said, finishing the last part of his sentence.

Mu Xiaoyu stopped in her tracks, her face immediately turning serious: "Senior brother! I don't think the White Rainbow Sword actually hurts that much!"

"So, Junior Sister still wants to practice with the White Rainbow Sword?" Li Yinsheng asked.

"Yes!" Mu Xiaoyu nodded emphatically.

Then, somewhat uneasy, she asked, "So, will Senior Brother really let me practice the Light Sword for half an hour less?"

"Of course, I'm actually still considering it. Reducing it by half an hour might not be enough. Maybe I should reduce it by a whole hour," Li Yinsheng said with a smile.

"Senior brother! I'll practice with the White Rainbow Sword from now on!" Mu Xiaoyu said without hesitation.

With a resolute expression, she gripped the White Rainbow Sword tightly, enduring the stinging pain in her body each time she used the Yin-Yang Dividing Light Sword, and began to perform the sword technique again and again.

Seeing this, Li Yinsheng nodded in satisfaction.

He wasn't lying to Mu Xiaoyu; he genuinely intended to reduce Mu Xiaoyu's sword practice time.

Because he had another very important matter to attend to, which was to be included in his junior sister's daily schedule.

But his schedule is already full, so he has to reduce the time he spends practicing martial arts or swordsmanship to make time for this.

Cultivation is the foundation, and the time spent practicing cannot be reduced.

As for sword practice, with the assistance of the Yin-Yang Dividing Light Sword, the junior sister's progress has greatly increased, and it's not a big problem to cut back by half an hour.

Just as Li Yinsheng was pondering, Mu Xiaoyu, who was practicing the Yin-Yang Dividing Light Sword, suddenly let out a soft shout.

As she thrust her sword forward, the single sword light instantly split into two and shot out.

Moreover, each of these strikes was several times better than the previous single sword light.

Li Yinsheng's eyes lit up.

Although it's just a matter of increasing from one sword light to two sword lights, it's indeed very easy, and my junior sister had already practiced for two days before.

The fact that one could master two sword lights so quickly demonstrates just how beneficial the White Rainbow Sword can be.

Of course, this is still incomparable to a true master like Li Yinsheng. In the past two days, he only took some time to practice the Two Elements Dividing Light Sword, and now he can divide it into ten sword lights.

The White Rainbow Sword was even more effective than Li Yinsheng had anticipated.

Not only did he help his junior sister master the second sword light shortly after acquiring it, but they also practiced until late at night, and even the third sword light was beginning to take shape.

He estimated that if he practiced diligently enough tomorrow, he should be able to complete the third sword light.

However, he needs to take his junior sister to Baoguang Temple first tomorrow.

Besides wanting to replenish her snack collection, it was also for the sake of adding it to her schedule.

……

The next day, in the morning.

The enlarged nine-foot-long Hanming Sword fell in front of Baoguang Temple.

Wearing a bamboo hat, Li Yinsheng pulled Mu Xiaoyu off the sword and put it back into his Qiankun bag.

"Let's go, let's wander around and see if there's anything you're interested in eating," Li Yinsheng said.

"Hmm!" Mu Xiaoyu touched the Qiankun bag at her waist, her face full of excitement.

This time she's going to fill the entire Qiankun Bag!

Mu Xiaoyu rushed into Baoguang Temple first, and Li Yinsheng adjusted his straw hat and followed behind her.

After a while, Mu Xiaoyu, who was browsing, eating and buying at the roadside stalls, turned a corner and saw a shop surrounded by a group of cultivators.

The monks, just like ordinary people, crowded together at the shop entrance, creating a noisy scene.

"What are they selling inside? Business is booming, there are so many people queuing up."

Mu Xiaoyu held a string of candied hawthorns in her left hand and a bamboo tube of "Ganlu Niang" in her right hand, tilting her head to look at the surrounded shops.

But she soon realized something was wrong.

The monks surrounding the shop didn't seem to be queuing; they seemed to be...

curse?

Li Yinsheng followed her from behind, patted her on the shoulder, and laughed, "What's wrong? Didn't you recognize that shop? That's the Casting Furnace Shop where we bought the Quenching Yuan Lock for you last time."

Mu Xiaoyu looked up at the somewhat familiar plaque, a look of realization flashing in her eyes.

Oh, so it really is this shop.

No wonder so many people were surrounding and cursing him.

Well said! He deserved it!

With the weight of over 300 jin of the Tempering Yuan Lock hanging on her body, Mu Xiaoyu took a big bite of the candied hawthorn and a relieved smile appeared on her lips.

Li Yinsheng patted her head: "Interesting. Come on, let's go see what's going on."

Those people definitely didn't come to block the door because they bought the Quenching Yuan Lock.

He was genuinely curious about what had happened.
