Junior sister, I really need to control you.

Late at night, on the third floor of the Xuanzhen Temple's Sutra Repository.

Li Yinsheng held a bright lamp, activated it with his magic power, and illuminated the surroundings as he carefully examined the bookshelves containing cultivation techniques.

Half an hour ago, he had already taken Mu Xiaoyu, who was exhausted from practicing, back to her own room.

The effects of the Tempering Yuan Lock were far better than he had expected. After Mu Xiaoyu finished practicing today, he carefully checked her progress and found that, despite consuming ten Nourishing Yuan Pills, her cultivation results were 40-50% stronger than before.

Although it's still not enough for the Taoist exam, it's already very fast.

At this rate, even though my junior sister lacks innate talent, her cultivation speed in the first three levels will not be much slower than that of someone with innate talent.

After all, even if ordinary disciples have talent, they don't have access to the Tempering Yuan Lock or the unlimited supply of Nourishing Yuan Pills.

After sending his junior sister to rest, Li Yinsheng returned to his room, merged the Blood Refining Pivot with his heart, and refined it.

After refining it, he also cultivated for the time it takes for an incense stick to burn. Although tempering his blood and qi with the fire element was indeed unbearably painful, as if boiling water was being poured into his limbs and bones, it was also quite effective in tempering his blood and qi.

However, he did not continue his cultivation.

He had only cultivated the Qingxuan True Scripture before because he didn't want to be distracted and hinder his cultivation.

But now that we have the Blood Refining Pivot, it would be more beneficial to supplement it with a body-refining technique.

Although he has the Blood Refining Pivot, he can temper his blood and qi on his own while cultivating, even without body-refining techniques. However, he guards the entire Xuanzhen Temple's Scripture Pavilion, so he is not lacking in cultivation techniques.

He's now actually a little worried about having too many choices.

Apart from the Zhenguan cultivation method, which has been lost, all other cultivation methods in the Sutra Repository are well preserved, including many high-grade body-refining methods, each with its own unique characteristics.

"The Five Chariots and Three Vehicles to the Life-Giving Technique uses the metaphor of sheep, deer, and oxen pulling carts to transport and circulate Qi and blood throughout the body. It is divided into five stages: Sheep Chariot (Minor Vehicle), Deer Chariot (Middle Vehicle), Ox Chariot (Major Vehicle), Great Ox Chariot (Upper Vehicle), and Great White Ox Chariot (Supreme Vehicle)..."

"That sounds interesting, but it's clearly stated that it can't be used as a supplementary cultivation method. To practice it, one must abandon the original method and switch to pure body cultivation. I won't learn it!"

"The Golden Skin and Jade Bones Longevity and Qi Cultivation Scripture? Hmm, seven parts body refinement, three parts qi cultivation, its main effect is to preserve youth and prolong life. It's not good for combat, but it's quite helpful for dual cultivation... What's the use of this? I won't learn it!"

"The Serpent's Tendon-Changing Technique? Uh, it requires so many serpentine beasts' gallbladders and tendons? That's too expensive. And it mixes body cultivation and poison cultivation methods together, isn't it just like biting off more than you can chew?"

"The Buddha Speaks of the Sutra of the Mighty Warriors Moving Mountains... How come there are Buddhist techniques here? Buddhist techniques emphasize complete sets; once you learn one book, you have to learn the whole set. You can't just not learn it!"

"Demon and ghost skin-changing techniques? Holy crap! How did demonic cultivation methods infiltrate this place? How come the seniors in the temple collect all sorts of things?!"

"The Three Yang Bone Refining Technique... Three Yang? This sounds somewhat compatible with the Bing Fire Qi of the Blood Refining Pivot. Let me take a closer look... Tsk! Limited to women only? Why?!"

After searching for a long time, Li Yinsheng finally selected a body-refining technique that he was satisfied with.

"The True Blood Manual," Li Yinsheng stared down at the crimson book in his hands, "using the power of pure blood and qi to refine one's own essence and blood, further refining it into true blood... It's actually a body cultivation technique primarily focused on blood refining! And it can be used as a supplementary method!"

As far as he knew, there were many branches of body cultivation, including those that focused on refining blood, tendons, bones, skin, and genitals.

While these schools of thought each have their own strengths and weaknesses, and are not ranked in any particular order, the Blood Refining path is generally recognized as the most comprehensive and also the most difficult to master.

Ultimately, the foundation of body cultivation lies in qi and blood.

Other approaches often involve first strengthening one or several parts of the body, and then replenishing and strengthening the body's Qi and blood.

The Blood Refining School, on the other hand, directly strengthens the Qi and blood, which then nourishes the entire body, including tendons, bones, skin, organs, and meridians. Every part of the body benefits, and even the hair becomes more vigorous and resilient than others.

While the path of bone refining also includes tempering bone marrow to strengthen qi and blood, it ultimately cannot compare to the true blood refining school.

Of course, blood refining is therefore the most difficult and slowest to progress among all body refining styles, and thus it is not the mainstream.

Of the many cultivation techniques he had just reviewed, only the "Five Chariots and Three Ascensions to Life Technique" was a technique that focused on refining blood. In terms of both its purpose and power, it was subtly a level stronger than the techniques of other schools.

Unfortunately, it can only be practiced as a main skill, not as a secondary skill, and it is clearly stated that the practice is slow and practitioners need perseverance.

"This True Blood Secret Manual is in no way inferior to the Five Chariots and Three Transformations Life-Sustaining Technique, but it seems to be even slower to cultivate..."

"However, this True Blood Manual can refine essence blood into true blood in addition to tempering qi and blood, so it can be considered a double benefit."

"According to the description, the benefit of one drop of true blood to one's own qi and blood is equivalent to that of three drops of essence blood. Moreover, when it is necessary to consume essence blood, using true blood as a substitute is not only more effective and causes less damage to the body, but also results in faster recovery."

"And most importantly, when this technique is practiced to a high level, it can even increase the upper limit of essence blood... no, it should be called the upper limit of true blood." Li Yinsheng nodded in satisfaction.

Essence and blood are the foundation of a person's vital energy. Generally speaking, a cultivator who does not cultivate his body has only a dozen or so drops of true blood in his body. Losing even one drop will severely damage his vital energy, and losing more will shorten his lifespan.

Unless the right rare and precious materials are found, it will be difficult to make up for it in this lifetime.

Body cultivators will have significantly more essence and blood, but it's usually only a few hundred drops, and it's equally precious, as it relates to their strength, lifespan, and foundation.

The true blood cultivated from the True Blood Secret Manual is not only more useful than essence blood, but also easier to recover, and even more abundant than the essence blood of ordinary body cultivators.

According to the cultivation manual, the True Blood Secret Manual has twelve levels. Cultivating to the third level yields nearly a thousand drops of true blood, while cultivators at the ninth level can have true blood accounting for up to 10% of their total blood and qi.

For ordinary cultivators, burning their essence blood is a life-threatening act, but for cultivators who have cultivated the True Blood Scripture to a high level, burning it occasionally for fun is not unacceptable.

However, this technique has both significant advantages and major disadvantages.

The True Blood Manual repeatedly emphasizes that one must use "pure" blood and qi to refine one's essence and blood. This means that many medicinal herbs and pills commonly used by body cultivators to aid in body tempering cannot be used in the True Blood Manual.

Because true blood is purer than semen, it allows almost no impurities.

Body cultivators are already slow to cultivate, and if they are not allowed to use medicinal herbs to help them, it will only make matters worse.

Of course, it's not completely unusable—

The cultivation method specifically lists some precious medicinal herbs and rare treasures that can be used, but even the cheapest of these listed items costs tens of thousands of talismans.

If I had to put it into words, this method is "either don't use any medicine, or use expensive medicine." Cheap medicine is absolutely out of the question.

Under these circumstances, practicing this skill becomes exceptionally slow.

As for slow... so be it. In that dilapidated place, time was the one thing he had no shortage of.

Having chosen his cultivation method, Li Yinsheng simply sat down cross-legged on the spot, carefully read through the introductory chapter of the "True Blood Secret Manual" several times, and then began to cultivate in meditation.

This cultivation was even more difficult than when he had just tried to use the Blood Refining Pivot to assist in tempering his Qi and blood.

At that time, he only needed to cultivate the Pure Profound Scripture while enduring the burning pain. It couldn't even be considered multitasking; it was just a test of his endurance and tranquility.

But now he has to practice the Pure Profound Scripture while guiding his refined blood and qi to circulate using the methods of the True Blood Secret Manual, which is truly multitasking.

Moreover, while doing two things at once, he still had to endure the burning pain.

Just two hours later, Li Yinsheng opened his somewhat tired eyes.

With his current level of cultivation, although he cannot go without sleep forever, he can certainly stay refreshed for several days without sleep.

But after only two hours of practice, he felt physically and mentally exhausted.

This was only because he had honed his tranquility for countless years in that broken cave where he received the reward; otherwise, he certainly wouldn't have been able to endure even an hour.

However, all this trouble was worthwhile.

His "True Blood Manual" has truly reached the first level, and he has already refined a drop of essence blood into true blood.

Although the Blood Refining Technique is slow to cultivate, he has the foundation laid by the first three levels of the Pure Profound Scripture, with abundant vital energy and vigorous blood. Therefore, it is only a matter of time before he can complete the first level. Two hours will be enough.

However, at the same time, he couldn't help but feel a little emotional.

Although the first three levels of the Qingxuan True Scripture are not entirely about tempering the body and refining qi and blood, the foundation accumulated in these three levels is only enough for him to officially complete the first level of the True Blood Secret Scripture.

This True Blood Manual is indeed quite difficult to master.

Moreover, after this training, the foundation accumulated by the Qingxuan True Scripture has been completely transformed into the True Blood Secret Manual, so subsequent training will proceed at a normal pace.

It would be quite optimistic to think that the second level could be completed within five years.

Li Yinsheng scratched his head.

He felt a tingling and itchy sensation on his scalp.

He knew why; the opening of the True Blood Manual reminded cultivators that "hair is the remainder of blood."

Once the first level of the True Blood Manual is completed and the first drop of true blood is obtained, the qi and blood will undergo an initial qualitative change. This will be reflected in the body by making the hair thicker, darker, and stronger.

That's why he had this tingling sensation on his scalp.

The True Blood Manual also says that there is no need to panic in this situation. You will get used to it after a few hours or days and will not feel anything anymore.

"Hmm... I'm a little tired now, but not really sleepy... and my hair is itchy, so I can't fall asleep even if I want to."

Li Yinsheng scratched his head and glanced at the sky, which was beginning to lighten with the first light of dawn.

"Forget it, it's almost dawn. I can't sleep anyway, so I'll go wake my junior sister up and guide her in her cultivation!" Li Yinsheng got up from his cross-legged position and stretched.

"She just started using the Qi Refining Lock; she needs more practice to adapt quickly!"

He didn't know when the next task would be issued by the cheat system. If he didn't have any new aspirations for cultivation, he would have to start thinking about earning money from talismans.

The next tier of 30,000 talisman coins corresponds to a reward of twenty years of cultivation.

If he cultivates for another twenty years, he will definitely be able to break through to the ninth level of the Pure Profound True Scripture, and the True Blood Secret Manual can also reach the third or even the fourth level.

……

Meanwhile, in Mu Xiaoyu's bedroom.

Mu Xiaoyu, who was fast asleep with her blanket in her arms, suddenly shivered in her dream for no reason.

Then he sneezed loudly again.

Still asleep, she rubbed her nose and drifted back into a sweet, warm dream.

In her dream, her cultivation soared to the heavens, rising from a nominal disciple to a formal disciple. She was then accepted as a true disciple by a reclusive master in the temple, becoming the senior sister revered by all the disciples. Finally, after overcoming numerous hardships, she became the abbot of Xuanzhen Temple.

Then, as the abbot, she ordered that strict and bad senior brother to cultivate for six hours every day!

Six hours!

Hahahaha!
