Yasenia read the book extremely fast. Her brain spun as it absorbed all the knowledge in close to no time. She had already read the theory, so she was memorizing the most basic procedure at that moment.
Although Yasenia wouldn't be able to understand the complex parts, her extremely powerful comprehension abilities made it so she could read, understand, and internalize the first chapters.
She found the basic treatment to reduce the efficiency of the Yang energy with Yin energy and focused on it.
The book focused on treating Yang with Yin and vice versa. These treatments varied a lot, so although they could be summed up in a sentence, the book had many different procedures within.
Yasenia turned Kali over, placing her on her back. The fox was limp, so she had no problems in moving her around. Then she took out a set of 81 needles.
They were kept in a cloth roll, ordered from the smallest to her left to the longest on her right.
Yasenia unrolled it and observed them. Each was very thin, and their length varied from seven to fifteen centimeters.
They were divided into batches of nine, each group increasing the length by one centimeter. The group of fifteen-centimeter needles was different since she had a total of eighteen compared to the other groups of nine.
The color of all the needles was black, again, with the last eighteen being different. The eighteen biggest needles were divided into two groups—a set of golden needles and another set of silver needles.
For this procedure, she needed a total of eighteen needles. Since she was treating her overwhelming Yang energy, Yasenia used the silver needles to guide it with her Ying energy. She used a total of four silver needles, and the rest were black.
With everything prepared, Yasenia began to work. The world around Yasenia disappeared as her golden slit eyes thinned and focused on the woman before her. Her energy flowed in harmony, and her hands and heart were steady.
Her hand moved slowly yet smoothly, and picked the black needles. She coated them in pure energy and approached her naked chest. Then, the first needle pierced above her left breast slowly until it hit the acupuncture point.
These points were nodes inside the cultivator's body that helped the meridians circulate the energy in complex patterns. Therefore, damaging these acupuncture points may result in considerable amounts of damage.
Some special acupuncture points were located in sensitive parts like the brain, heart, dantian, and many more. These points could mean death if something broke them with accuracy. However, one must be extremely knowledgeable of someone's body to pierce these with precision.
As previously mentioned, Yasenia had studied medicine and anatomy in the past, so it wasn't difficult for her to sense them.
Right now, the difficulty of her task was the same as following a somewhat complicated cooking recipe. If she fucked up, it would end up very badly, but the recipe was very detailed, so unless she were distracted, it would be hard to mess up.
As the needles pierced Kali's skin, she revolved her Yin energy and slowly inserted it inside of her.
The dragoness used this energy to counter the Yang energy inside Kali.
Since she was treating energy problems, Yasenia needed to pierce them in the dantian area. Some sweat accumulated on Yasenia's nose as she moved her hand. She was slowly approaching the first silver fifteen-centimeter needle toward the dantian area.
If that book resulted in being a scam or something, she would be effectively crippling Kali. However, her thoughts only lingered there for a second and continued forward. 'Although doubting is good, I haven't seen a single misleading treasure in the town. All the things we bought were legitimate, so it would be extremely bad luck for this book not to be.'
Yasenia began piercing Kali's skin in the dantian area with extreme concentration.
Angel felt a strange pressure emanating from Yasenia as the first silver needle slowly sank into Kali. It wasn't big or suffocating. It had a touch of mystery.
The second needle pierced two centimeters down to that one. Each silver needle would be piecing in each of the cardinal directions taking the dantian as a center.
Four black needles surrounded them, also piercing in cardinal directions with the silver needles as a center.
If you painted the needle-piercing points with a marker, it would effectively create the three-in-a-row play table. It was one of the most basic acupuncture formations but effective for what Yasenia wanted.
The fifteen-centimeter thin needles sunk into Kali's skin. Yasenia pierced one after another, plunging all the needles inside Kali.
Then, she followed the technique and revolved her Yin energy, seeping it through the needles inside Kali's body. The small amounts of Yin energy she previously inserted multiplied in might at that moment, counterattacking the Yang energy inside Kali.
It was a success!
However, Yasenia didn't celebrate too early, 'Don't lose focus. Until all the needles are outside, there is still danger.'
Kali's sluggish mind felt something refreshing lodging into her dantian area and spread across her body. The hotness and pleasure that was attacking her body were put off by that invigorating energy.
It was at that moment that Kali's burst of strength happened inside her soul realm, annihilating the Heart Demon. Her strength, assisted by Yasenia's acupuncture, gave the Heart Demon a lethal blow making it slowly dissolve in golden particles.
Kali felt the Yin energy around her body and didn't resist it because even if it was the opposite of her dearest hot and passionate energy, in essence, it was the same.
Kali knew that this energy was Yasenia's, so she welcomed it with delight.
Like a water tide on a burning forest, it put out the fire with ease and nurtured Kali's damaged nervous system and meridians.
The Yin energy finally reached her mind, and her brain reactivated.
Inside her soul world, Kali felt something pulling her out. She smiled and looked at the beautiful sky inside her world. "Time to go back. I'm very excited to know what Yasenia will say."
The energy didn't immediately wake her up. It was careful and caring, the same as its owner. She felt as if something was gently cooing her out of her sleep.
One minute later, Kali's eyes regained focus. She saw the same white ceiling and the curtains on the side of the bed. Beside her, the naked Yasenia was focusing on her abdomen area.
She was sweating as she manipulated her Yin energy toward some needles stuck in her. Even though those needles were piercing dangerously close to her dantian, Kali didn't feel any fear. 'Did she use the acupuncture manual to help me? She is really a monstrous genius. To be able to already use the most basic procedure... I have no words to explain how proud I feel for her.'
Yasenia stopped five minutes later and took out the needles one by one, careful not to mess anything up.
Kali saw the nervousness in Yasenia's golden eyes as she took them out one by one and almost laughed aloud. Yasenia looked very cute in Kali's eyes.
However, she held it in as she didn't want to interrupt her dear dragoness.
When the last needle got out, Yasenia sighed with relief, and her arms fell to the sides. 'I've done it. Thankfully, I didn't mess it up. My energy also didn't react strangely with the needle technique. I always had my heart thumping, thinking that it could go wrong.'
Kali spoke with a weak voice. "Thanks for your hard work, my love."
When Yasenia saw her like that, her heart tightened. She threw herself on top of Kali, hugging her strongly. "Thank the Heavens that nothing bad happened to you. How do you feel, Kali? I'm so sorry. I should have released outside."
Kali grunted as the voluptuous dragoness threw herself on top of her. The sweaty soft body smelled heavenly and covered her completely, igniting a small flame inside of Kali.
She didn't know whether to laugh or cry, 'My dearest is sometimes too clueless at her own attractiveness.'
Angel also asked while patting Kali's head, "You have to tell us, Kali. You better not hold anything back!"
Kali smiled weakly but tenderly. She felt so full of love right now. "I'm very tired and drained. I can't feel my legs because of the powerful orgasm numbed my lower part. But I'm okay."
Yasenia kissed her slowly and tenderly. "I'm glad nothing serious happened. Here take this."
Kali saw a pill appearing and easily discerned it as a very high quality [Yin replenishing pill]. Kali didn't make a fuss and ate it. If she dared to ask for a lower-quality one, she didn't know if Yasenia would spank her until her butt was red. 'Although... Maybe I have to feel something like that another day. Evelyn is quite fond of that, so it shouldn't feel too bad being spanked, right?'
She opened her mouth obediently, and Yasenia fed her the pill. Kali gulped it down, and since it was a mid-level Heaven-ranked pill, she felt reinvigorated almost instantly.
Kali was about to speak about the heart demon when she saw the bloody marks on her neck. Her eyes widened and she asked, "What happened, my love? Are you okay!?"
Yasenia tilted her head cluelessly for a second, but then she remembered. She laughed and smiled, pecking Kali, "My dear fox gave me love bites and scratches~, how could I not be okay?"
Kali almost spluttered, "Love bites!? If those are love bites, eating someone would be called love cannibalism!"
Yasenia and Angel laughed aloud. Yasenia, still lying comfortably on top of Kali, said, "Don't worry about that, honey. During the treatment and our current conversation, they only look scary."
Yasenia took out a towel and cleaned her bloody neck to show pink skin below, "See? It is already healed~."
Kali blinked twice, then she said, "Here, eat this. [Healing sap]."
Yasenia saw a green substance appearing on Kali's hand. Then, she moved her hand toward Yasenia and Yasenia ate it without complaints.
The small wounds she still had closed in thirty seconds. Angel took the chance to clean Yasenia with that towel.
Kali was feeling more aroused as time passed because Yasenia was still on top of her. She could feel everything, especially that powerful weapon that sent her to another realm a moment ago.
Yasenia's lips lifted as she felt Kali heating up again. 'Now that I released, I can control myself better~. Note to self, even if I have to masturbate, release some arousal before doing it with Kali.'
Kali hugged Yasenia's neck and smiled, "Yasenia, do you know that something very important happened?"
Yasenia blinked twice and said with doubt, "That we finally became one?"
Kali lifted an eyebrow and said, "Then, two important things happened. Moreover, you only inserted the tip. I want to have you completely inside of me."
Yasenia chuckled huskily and kissed her, "We can solve that problem reaally fast~, honey."
Kali felt Yasenia's weapon rising for battle and gulped. However, she wanted to speak about the Heart Demon before something else happened. "When you sent me in that powerful orgasm, I returned to my soul world to fight the Heart Demon."
Yasenia's smile disappeared, and her eyes widened, "Are you okay? Do you feel anything strange?"
