Junior sister, I really need to control you.

Inside the main hall of Xuanzhen Temple.

Mu Xiaoyu hung limply in the air.

If Li Yinsheng hadn't used his telekinesis to support her, she would have collapsed to the ground long ago.

Supported by the manipulation technique, Mu Xiaoyu raised her head, her hair falling loose and covering most of her delicate face, making her look like a female ghost, staring resentfully at Li Yinsheng.

"Senior brother, before you went up the mountain, were you a jailer in the mortal prison?"

"I've been cultivating in the mountains since I was young, so of course I've never worked as a jailer in the mortal world," Li Yinsheng said, puzzled. "Why do you ask, Junior Sister?"

"Because I was just being tortured!" Mu Xiaoyu cried out with tears in her eyes.

"After all, what I just used was the Pure Profound Divine Light, which can cleanse and transform one's marrow, so it's inevitable that it will hurt a little," Li Yinsheng comforted him.

"Junior sister, don't worry. Although this technique will cause a little pain when it cleanses the body, it will only benefit the body and will not cause any harm."

As he spoke, Li Yinsheng brought over a prayer mat, placed it under Mu Xiaoyu, and helped her sit down slowly on the mat.

"A little bit of pain?! I feel like I'm going to die from the pain! It feels like a million needles are shooting around inside my body!"

Sitting on the futon, if her body hadn't been so weak, Mu Xiaoyu would have loved to pounce on Li Yinsheng and bite him.

Faced with Mu Xiaoyu's resentment emanating from him, which was so intense it seemed almost tangible, Li Yinsheng remained remarkably calm and spoke leisurely.

"But junior sister, haven't you noticed that you feel completely refreshed now, and the fatigue from practicing has also subsided considerably?"

Mu Xiaoyu was taken aback.

The pain she just experienced was so intense that she is still feeling lingering fear.

Only after Li Yinsheng reminded her did she realize that she was indeed feeling a little different.

After the pain subsided, although she still felt listless, she definitely felt less tired.

Moreover, she did indeed have a faint feeling of "complete comfort" as Li Yinsheng had described.

It's not the definite comfort of sunbathing or sleeping in late, but a kind of relaxation that comes from feeling as if your whole being becomes clear and transparent.

"And most importantly, junior sister, you lack innate talent, so your cultivation is slower than that of ordinary people. Although the Marrow Cleansing Technique cannot give you innate talent, it can make up for some of your disadvantages," Li Yinsheng said.

"So my cultivation is faster now?" Mu Xiaoyu was delighted.

She wasn't particularly concerned about how fast she cultivated, but faster cultivation meant she would reach the second level in a shorter time.

Then she can secretly manipulate the Tempering Lock herself!

"This one time is far from enough," Li Yinsheng said. "Washing the tendons and marrow requires perseverance, like accumulating sand to build a tower."

"Huh?" Mu Xiaoyu's face paled instantly. "Then we have to do it a few more times?"

"Hmm... it's a bit troublesome to count by the number of times," Li Yinsheng said. "If we cleanse our marrow once a day, I estimate it would take about half a year."

"Half a year!" Mu Xiaoyu exclaimed in horror, stumbling to her feet from the futon. She turned and ran, "Senior brother, I'm sleepy, I'm going back to sleep!"

"Hey, junior sister, don't rush off, I haven't finished speaking yet."

Li Yinsheng raised his hand and pointed, using his manipulation technique to freeze Mu Xiaoyu in place.

Mu Xiaoyu was forced to turn around and face Li Yinsheng.

"This process of cleansing the tendons and marrow is inevitably painful, but the pain is because the Pure Profound Divine Light is purifying the impurities in the body," Li Yinsheng said. "In other words, the fewer impurities in the body, the less likely it is to hurt."

"So... the pain of cleansing the meridians and marrow will gradually lessen?" Mu Xiaoyu asked thoughtfully.

"Not bad." Li Yinsheng nodded. "When you feel no pain at all during the cleansing of tendons and marrow, it means that the cleansing of tendons and marrow by the Qingxuan Divine Light is complete."

Of course, this only means that the cleansing of tendons and marrow by the Qingxuan Divine Light has reached its limit.

The most important function of the Pure and Profound Divine Light is to purify the mind, dispel illusions, and subdue demons and monsters; cleansing the marrow and tendons is only a secondary function.

While its effects of cleansing the tendons and marrow are not bad, they are not excessive.

If a better method of cleansing the marrow and tendons is found in the future, the pain will still occur.

Facing Mu Xiaoyu, Li Yinsheng patiently and persuasively guided her, one sentence after another.

"So, junior sister, this is the most painful time you've ever undergone the cleansing and marrow-refining process."

"The pain will only decrease in the future, but your cultivation speed will only increase after each marrow cleansing."

"You've finally endured the most painful first time, but your cultivation speed hasn't improved much. Don't you think that's a huge loss?"

Mu Xiaoyu was taken aback.

Although she felt there was something off about what he said, upon further reflection, she had to admit that it did make sense.

Having endured the most painful torture, yet receiving only meager rewards, I am indeed somewhat resentful.

Especially since my senior brother said that the pain will gradually lessen...

"Then... Senior Brother, do we still have to undergo the Marrow Cleansing tomorrow?" Mu Xiaoyu asked hesitantly, "But it really hurts so much..."

Although she wavered somewhat, she still couldn't make up her mind.

"Hmm... Junior sister is so resistant? It seems I was a bit too hasty. If I had known this would happen, I should have taken it step by step and let you adapt slowly."

Li Yinsheng pondered for a few moments, his face showing just the right amount of apology and concern, and spoke softly and sincerely.

"If my junior sister needs to undergo marrow cleansing tomorrow, we can halve the time from this session to allow her to adjust first, how about that?"

So, the time can be halved?

Mu Xiaoyu, who had been hesitant, was overjoyed when she heard the good news.

"In that case, I'll try again tomorrow...?" She was still a little worried. "But what if I still feel a lot of pain?"

"It's not too late for junior sister to give up then," Li Yinsheng said.

But if you give up then, it means, "You've already endured the most painful experience once and the second most painful experience. Giving up now would mean suffering those two most painful experiences for nothing. Are you really willing to accept that?"

……

Early morning, in Li Yinsheng's bedroom.

He was sitting cross-legged on a futon, enveloped in a hazy, soft light.

A moment later, he slowly opened his eyes, and the clear light returned to his body.

"This Pure Profound Divine Light really does cleanse the tendons and marrow, which is quite painful. No wonder my junior sister is complaining so much," Li Yinsheng said with some emotion.

After coaxing and cajoling Mu Xiaoyu into agreeing to continue the marrow cleansing last night, Li Yinsheng sent her back to sleep.

He then began to cleanse his marrow and tendons using the Qingxuan True Scripture in his room.

His experience of cleansing his marrow and tendons was similar to what Mu Xiaoyu had described last night; it was indeed a dense, stinging pain, as if many sharp needles were running all over his body.

However, for Li Yinsheng, who had been tormented by the Blood Refining Pivot for more than a decade, this stinging pain was easy to get used to.

In his opinion, this stinging pain was much more pleasant than the burning pain of the Blood Refining Pivot.

Although it is slightly stronger than the burning pain of the Blood Refining Pivot at the beginning, it will gradually decrease.

The Blood Refining Pivot is different; its burning pain is persistent.

Of course, the benefits brought by the Blood Refining Pit are also enormous.

During this cultivation, he not only reached the tenth level of the Pure Profound True Scripture, but also the fifth level of the True Blood Secret Manual.

Li Yinsheng raised his right hand, took out a piece of ironwood the size of a water cup from his Qiankun bag, held it in his palm, and squeezed and twisted it with his five fingers. The hard ironwood turned into a clump of wood chips in his hand.

He clapped his hands, brushing away the wood chips from his palms. His palms were smooth and white, without a trace of red marks or injuries.

Ironwood is slightly less hard than ordinary cast iron, but not by much.

He estimated that with the physique of the fifth level of the True Blood Manual, turning iron into mud should not be a problem.

The wonder of the third level of the True Blood Codex is that it can increase the upper limit of True Blood.

Moreover, this upper limit is not fixed after the third level is improved; it will still increase again as the True Blood Codex is upgraded.

At the third level, the True Blood Secret Manual has a maximum limit of one thousand drops of condensed true blood.

Li Yinsheng's current fifth level has had its upper limit raised to three thousand drops.

Moreover, because he has been honing his skills and cultivating over the years, his true blood has basically reached its limit.

He had originally planned that if he didn't have any new aspirations for cultivation, he would go out and earn some money to claim the next tier of reward for his accumulated talisman money.

But now his next step is to consolidate his cultivation and break through to the True Person realm.

He did not intend to directly enter the cave and work in seclusion, but instead to break through on his own according to the methods recorded in the Qingxuan True Scripture.

The Xuanzhen Temple's Sutra Repository contains handwritten notes left by past masters, recounting their own cultivation experiences and providing reference and guidance for future generations. These notes are only for cultivators whose cultivation level has approached that of a true master to peruse.

Li Yinsheng hadn't read it before because he felt his cultivation level was still quite low at the time, and reading it might have made him overly ambitious, doing more harm than good.

But now that he is only one step away from breaking through to the True Person realm, he definitely needs to study these notes carefully and thoroughly before making any further moves.

Moreover, besides the cold, hard notes, there was also his uncle, a former master, in the temple who could personally impart his experience to him.

However, he hasn't figured out how to tell his martial uncle about his cultivation level yet.

He didn't intend to keep his cultivation level a secret forever, but he needed to find a suitable opportunity to reveal it.

"Let's go to the library and get a notebook first," Li Yinsheng said, getting up from the futon. "Then let's get up and start cultivating, Junior Sister."

"It's perfect that I can watch her cultivate while studying the notes left by the senior master, so that I can do both without any problems."

……

In the following month, Li Yinsheng, who had cultivated for decades, enjoyed a rare period of leisure in just a few days.

I would go and chat with my uncle every morning.

Then I went to the library to retrieve a manuscript left by a senior master, and then I went to wake up my sleeping junior sister.

Then, based on her current cultivation progress, slightly increase the weight of the Tempering Yuan Lock.

Then, all day long, I had to watch her cultivate while studying her notes.

When it got late at night, his junior sister had almost finished her training, so he sent her back to her room and used the Pure Profound Divine Light to cleanse her marrow and tendons.

After his junior sister fell asleep, he went to his room, closed his eyes to rest or took a nap, and used the Pure Profound Divine Light to cleanse his marrow and tendons.

And so it went until dawn, and then it was a new day.

With his current cultivation level, although he can't completely avoid sleeping, one or two hours of sleep each night is more than enough.

In the past month, he has basically mastered the parts about breaking through to the True Person level in those senior's handbooks.

Most of the practitioners there cultivate the Guanyin's (or Guanyin's) cultivation method, "Xuanzhen Baozhao Xinyin Zhenquan".

However, one senior master cultivated the "Qingxuan True Scripture," while three other senior masters cultivated other techniques that were no less powerful than the "Qingxuan True Scripture."

As for those who cultivated to become True Immortals using the "True Blood Secret Manual," there was not a single one.

He benefited greatly from the notes left by the senior cultivator who practiced the Qingxuan True Scripture.

He also gained a lot from reading the notes of other senior figures.
