After Chu Wuyao went through every book on the bookshelf, she finally found a body cultivation technique that interested her.
[Blood Demon Body: Through the absorption of the killing aura after a creature's death, the practitioner can temper their own body. Practicing this technique massively improves the practitioner's recovery speed.]
Compared to the other techniques that were either very slow, required special conditions to practice, or both, the Blood Demon Body was not only a little easier to practice, but was also very suitable for Chu Wuyao.
She could already get Sin Points through killing, and now, she would even be able to practice through killing.
Turning her gaze at the bottom of the cover, she looked at the price required to redeem it.
[Price: 10.000 Contribution Points. 100 Contribution Points for the Qi Accumulation Chapter.]
The total price was very expensive, but at least it could be exchanged for in different parts.
With a move of her hand, Chu Wuyao took out the Original Desire Sect's red token.
Surprisingly, the number at its top had changed, from 53 to 206.
Part of it was because she had previously exchanged all the items she gained form her trip to the Warring Beasts Forest, while the rest of it was "sponsored" by Ruan Yi.
Even though Chu Wuyao decided to not kill her, she still didn't let her contribution points go and took them with absolutely no shame.
Putting the red token on top of the book, the number on it decreased, but at the same time, the book that was previously locked could now be opened.
Chu Wuyao didn't rush to read it, but put it away and walked to the bookshelf that contained various miscellaneous books.
This time, she knew exactly what she was looking for and didn't have to search for long.
[Heart Seal: A skill that can leave a mark on the target's heart. With a thought of the user, the mark can be detonated, killing the target. It can only be used on people within the same realm of cultivation and the target has to not resist during the process of marking.]
[Price: 50 Contribution Points.]
Even if this skill was not as expensive as the Blood Demon Body, Chu Wuyao was still a little unhappy to spend her hard-earned contribution points.
Still, she exchanged it with a wave of her hand.
"It doesn't matter. Just think of it was spending Ruan Yi's contribution points.", she tried to convince herself.
The Heart Seal was the reason she chose to come to the Original Library today.
Chu Wuyao didn't trust Ruan Yi and could not let her go without making sure that she would not pose a threat to her in the future.
A skill like the Heart Seal was the perfect way to make sure that nothing went wrong.
After putting this books away too, Chu Wuyao didn't leave the library, but started going through the rest of the books.
She had read many novels in her past life and every protagonist was basically able to find some hidden supreme skill in the sect's library which then allowed them to reach the top of the world.
Chu Wuyao believed if other people could do it, then someone as outstanding and talented as her could do it too.
A few hours later, Chu Wuyao walked out of the library with a dark face.
"Sure enough, everything in the novels is a lie!", she muttered in dissatisfaction and looked at the library behind her.
She had spent many hours, gone through hundreds of books but still didn't find anything of value, let alone a hidden supreme skill.
Instead, she found all kinds of strange books with titles such as:
"How to Seduce Your Senior Sister", "The Story of My Domineering Master and I", "108 Ways to Betray Your Teammates", "Cooking Tips 101", "I Want My Senior Sister to Step on Me", etc..
Even Chu Wuyao had to admit that there were many talented people out there, who were willing to write about anything.
Holding the two books she had exchanged in her hands, she didn't stay any longer and quickly left this place.
Her steps were quite fast and she was obviously familiar with the road, so she soon reached her residence.
Sensing the situation inside, she saw that Ruan Yi was still here and was still sleeping soundly.
Chu Wuyao didn't enter, but sat down on the ground outside, opened the two books and started reading them.
As her cultivation had improved, so had her memory and she was able to easily memorize the knowledge about the Blood Demon Body and the Heart Seal.
Then, with a thought of her mind, she brought up the system prompts that appeared earlier today.
[You had a unique sexual experience while asleep. Sin Points +5]
[You had an "in-depth discussion" with Ruan Yi. Sin Points +50]
[You stole your companion's contribution points. Sin Points +5]
When she saw the first prompt, Chu Wuyao wondered if she had seen it wrong but after she read it carefully many times, she became sure that she didn't.
"This system isn't reliable at all.", she complained.
She understood that this was most likely the sin of sloth, but there should at least be a better way to phrase it than that, right?
Even though she complained about the system, she still brought up the system panel dutifully.
[Name: Chu Wuyao]
[Cultivation: 3rd Level of Qi Accumulation(2/40)]
[Techniques: Original Desire Sutra(1/100), Blood Demon Body(0/5)]
[Skills: Charm(9/10), Fog of Hallucination - 3(1/30), Illusion Eyes(9/10), Heart Seal(0/10)]
[Sin Points: 60]
Less than a day had passed, but the panel had changed once again.
Her cultivation and the Original Desire Sutra had increased as a result of today's fight with Ruan Yi, while the Fog of Hallucination had changed yesterday night.
Yesterday, she hastily put all of her Sin Points into the Fog of Hallucination skill in order to save her life.
What's strange is that when the value behind it was filled, the skill turned into Fog of Hallucination - 2 and could still be improved.
Moreover, the condition to practice a skill to perfection hadn't been fulfilled and showed no change at all.
This made Chu Wuyao know that practicing a skill to perfection doesn't mean just filling it up with points.
"There has been a change in the Fog of Hallucination skill after its change, but it has not changed qualitatively."
Chu Wuyao guessed that to practice a skill to perfection, she would have to practice it until it could no longer continue to be improved and she had become as familiar with the skill as its creator.
"But this also means that it is actually easier to practice skills that are weaker compared to the skills on the Original Desire Sutra."
After all, the difficulty between practicing a skill created by a Qi Accumulation cultivator and a skill created by a Supernatural cultivator was massive.
She noted this down and was ready to try it in the future.
Then, with a thought of her mind, she clicked on the (+) button and added points to the Heart Seal skill.
Information continuously poured into her mind but her movements didn't pause at all.
Only after the Heart Seal had changed into Heart Seal - 3 did she stop adding points.
Digesting the information that appeared in her mind, Chu Wuyao quickly became familiar with the Heart Seal skill and found that she could use it comfortably.
Glancing at her remaining Sin Points, she didn't immediately improve her cultivation, but improved the Blood Demon Body first, wanting to try something.
The Blood Demon Body flickered on the system, while a hot energy entered her body and quickly spread everywhere.
Her muscles contracted, her skin was stretched and Chu Wuyao felt that her physical strength was improving at a rapid speed.
Compared to improving her cultivation, this feeling was countless times more addictive.
Soon, the hot energy disappeared and Chu Wuyao was able to check the condition of her body.
"Not only has my physical strength skyrocketed, but my defense has also increased by a lot."
Tracing her sharp nails against her skin, Chu Wuyao found that only a few scratches appeared, which were already showing signs of healing.
One had to know that her nails could easily pierce through the animals' skin before, but now, it only left some scratches on her.
Taking a look at the panel, she found that the Blood Demon Body had changed into [Blood Demon Body - 2(0/10)].
"It seems that using the Sin Points on the Blood Demon Body is way more effective than spending it on cultivation."
She wasn't surprised and had already expected it.
Body cultivation is less popular than normal cultivation because it is way harder to practice.
In fact, body cultivation is as strong, if not even stronger than normal cultivation.
Chu Wuyao, who had a system, could obviously make use of this.
"Unless it is necessary, I should use my Sin Points on body cultivation and skills, while I cultivate the Original Desire Sutra on my own.", Chu Wuyao thought and made a brief, temporary plan for the near future.
No longer hesitating, she chose to continue improving the Blood Demon Body and enhancing her strength as much as possible.
Only by increasing her strength could she feel safe in this strange world.
