Inside the Noble Realm of the City of Muspelheim.

The dazzling rays of sunlight pierced Khan's eyes as his body awakened from slumber, he turned his head and found that he laid on Lily's bed, a faint alluring fragrance lingered in the air, Khan stood up, glanced at the messy bed before fixing it.

Khan rubbed his tired eyes and staggered towards the living room, there, he found Lily with her usual studying attire, her eyebrows frowned in concentration, looking at her slightly baggy eyes, it could be deduced that she didn't get that much sleep.

Khan looked at the other side of her table and found his favorite dough sticks and soymilk, he smiled.

'This girl... She knew that she would be busy, yet she still takes time to prepare a breakfast for me...' If Lily saw his smile, she would stare at him in shock, for Khan revealed the most brilliant smile that he ever showed in his entire life, for as long as he remembered.

Calming his fluttering nerves, Khan moved behind Lily and took a peek from behind her shoulder, Khan wore an amused smile, for she still didn't notice Khan that smiled beside her.

Khan pecked her cheek, startling the girl into a panic, she glanced at him with reddened cheeks, the former smiled before speaking.

"You're still studying? Judging from your face, you didn't get that much sleep, right?"

Lily lowered her head in shame, of course, she knew about her current condition, but how could a student miss their school's entrance examination? She gritted her teeth and forced herself to stand up.

"I told you that the sick should stay in bed! And also, you still haven't learned that material? We already studied that for several days!"

Lily rolled her eyes in annoyance, she glanced at him and murmured with an indiscernible tone.

"Hmmph, I'm not a monster, like you..." 

Khan, of course, heard this murmur and he replied with a chuckle.

"A monster? Or your memory capacity is just low?"

"Hmmph! Are you mocking me? I'll just let you know, but I have a good memory! I can even recite to you the entire Muspelheim's constitution!" Lily crossed her arms together and smugly smiled.

"Okay, then, what's the use of that for the Entrance Exam?" Khan gave a teasing look, the girl froze in shock and stared at him.

"Ahhhh!!!" She screamed, prompting Khan into a startle.

"What's wrong with you? becoming that hysterical..." She stared at Khan with thirsty eyes, Khan gulped and asked.

"What... is it...?" 

"Teach me..."

"Teach you, what?"

"Math..."

"Didn't you teach me that several days ago?!" 

"Yeah, but I forgot about what formula did I use to solve it..."

"..."

 Khan sighed, he glanced at the wall clock above the television, the time displayed, seven in the morning of May 1st. 

"By the way, what time does the examination start?"

"Huh? Ah, the exam? It starts at 12 sharp."

"So we still have time..." Khan leaked an ambiguous smile. Lily stared blankly for a moment before starting into a panic.

"I-i'm telling you I need to study!"

If you come across this story on Amazon, it's taken without permission from the author. Report it.

"Haah? What do you mean? I'm just gonna teach you a mental technique to improve your memory... It's not like we're gonna do anything, or wait..." Khan's eyes flashed with an avaricious light, he scanned her body and said.

"Could it be that you were expecting something...?" Lily's embarrassment condensed together and the shock she received seemed to be heavier than she expected as she tried her best to hide her complexion from Khan.

Seeing this great reaction coming from his little wife, Khan laughed for a moment before saying.

"Okay, okay, I'll stop with the teasing, I'll teach you the technique, so listen." Khan's face became solemn, he formed a mudra with his hand as a silvery glow materialized from his body.

"This technique doesn't require the use of Qi, instead, it uses soul energy to capture information and brand it into your mind so that you won't forget, easy right?" 

Lily stared at him in shock, how does he know such a high-level technique? Khan noticed her weird gaze and explained.

"This technique was taught by the Sect Master for me, so you better not tell anybody that I taught you this or else I will be done for." Khan assumed a solemn tone, of which Lily nodded in return.

After teaching her the method of circulating soul energy. Lily exclaimed in surprise.

"Woah, it really works! Now that I have an eidetic memory, let's study!" Lily's gloomy expression became cheerful, she excitedly opened her book and didn't even bother to take notes.

After about thirty minutes, she asked Khan to test her knowledge, Khan, of course, acknowledged and wrote several complicated mathematical problems.

Lily almost leaped in joy when she received the results that Khan checked. Not even an hour had passed since she learned the Eidetic Memory Technique and she could already obtain a perfect score in the entire module.

"Now that we have time, and it's still four hours until twelve, what should we do to kill time?" Khan spoke, his tone riddled with hidden intentions. Lily noticed the intentions hidden in his tone, but she just sat there, feeling a little ashamed of herself.

She, of course, wanted to explore more about her sexuality, but since she was just a normal girl until Khan took her, she still felt a little bit reluctant about letting herself indulge in the pleasures of man and woman relations.

But thinking back at the events yesterday and how Khan consoled her for the entire night, she took a deep breath and looked as if she decided on something. Amidst Khan's stare, she went into her room and took a familiar golden book from her cabinet.

 She returned back to the living room with the golden book held on her chest, Khan stared at the book with an incredulous thought in his mind.

'C-could it be that... she wants to cultivate in that method...?' Khan gulped, and thinking back at the events in the recent days, his lance readied itself and displayed its utmost glory.

Lily placed the book on the table with a wildly beating heart and a furious blush on her face. On the cover of the book, painted a title, written in an enticing fashion.

[Yin-yang Assimilation Method]

Khan stretched his hand and opened the book, the first page revealed a solemn message that the person that should cultivate this method needed to have a partner that they could entrust their life into.

The book indicated that since the Yang is more domineering than Yin, the man should be the one to take the lead and converge a mass of Yang Energy from his body to connect with the Yin.

The Yin would suck all the Yang Energy and circulate it around her bod, according to the book, the barbaric Yang Energy would become docile if it met a Yin energy that the Yang acknowledges, and so the book encourages that the partner of the man should be his wife or concubines.

The cultivation method had five layers.

Road, Gates, Door, Inside and Assimilation.

The duration to execute all five layers would last for three hours under the condition that the man could maintain his stamina and might.

In the final spurt, the circulated Yin and Yang would converge into each other's body, tempering and nourishing it with the life force that came from nature itself.

Khan stared in shock, not at the message, but the two words named three hours.

'I am supposed to last three hours?!' Khan's hand moved with the intention of flipping the pages, seeing this, Lily turned her gaze away, however, Khan didn't reprimand her, he just stared at the innocent Lily and flipped the page.

On the page were several positions that the couple should assume and the duration that it should last. It even had intricate details about how deep should the man penetrate to achieve the greatest effect.

He flipped the several other pages, burned it in his mind and closed the book with a sigh. 

Upon noticing that Khan returned the book to the table, Lily swiftly took the book and hugged it on her chest, she gave an awkward smile while speaking.

"Now that you've read it, I'll go take a sleep, see ya!" But before she could get away, Khan clutched her wrist with a big bad wolf smile on his face, before pulling her into his embrace.

"Sto-stop! It's still daylight, you know..." Lily tried to push him away but her complaints were blocked by Khan's lips. Khan forcefully opened the levee and drained the waters from the dam.

Lily who put up a resistance eventually succumbed to the attacks as she fell limp on Khan's arms, her eyes became glazed with a hint of desire.

"I endured so much last night, so It's time for payback!"

Inside the normally quiet mansion, two deep labored pantings could be heard, mixed with consecutive lascivious slaps, it was only until three whole hours had passed that tranquility once again descended and enveloped the entire mansion.
