"Everyone, leave at once," Wang Cheng said calmly, but with an authority that brooked no refusal. "The next stage of treatment requires utmost concentration. No one is allowed to disturb us under any circumstances... including you, Patriarch Li."
Li Hong hesitated, but upon meeting Wang Cheng's calm and confident gaze, he nodded compliantly. "I leave my daughter in your hands... Doctor."
"Just 'Uncle' is fine," Wang Cheng replied, before bolting the door securely.
Now... only three people remained in the room: himself, Liu Yuexin, and the unconscious Li Sumei lying on the bed.
"Uncle... Miss Li's condition..." Liu Yuexin asked with concern.
Wang Cheng walked to the bedside and placed his palm gently on Li Sumei's forehead. A heat as intense as an open flame radiated from her, so strong he could feel it clearly.
"As I said... Yin Fire is consuming her body from the inside. It is so hot that even a cultivator like you cannot touch her directly for long."
He turned to look at Liu Yuexin with a serious expression. "To extinguish this Yin Fire, there is only one way. I must use the strongest and purest Yang energy and inject it directly into her body to quell the flames. But the problem is... I do not know how much quantity is needed to put out this fire... And for this, you must help me."
"Help? How can I help?"
Wang Cheng sighed. "I need to create 'Biological Yang Medicine,' which is essentially my own Yang Essence. However... I have no taste for doing it with an unconscious body. Even if the girl before me is as beautiful as a goddess... it is not my way."
He spoke while turning to look at Liu Yuexin with a gaze full of deep meaning.
"Therefore... I must trouble you, Little Girl... to help wake up my 'Yang Dragon'."
Liu Yuexin's face flushed red to her ears, but she understood his meaning immediately. She nodded obediently without further questions. She walked over and knelt humbly before Wang Cheng, slowly undoing his sash.
The sleeping Yang Dragon was revealed. Liu Yuexin took a deep breath... No matter how many times she saw it, she couldn't get used to its formidable size. She slowly opened her small mouth and took it in with dedication.
Wang Cheng arched his hips to receive the soft touch of her mouth. His hands, however, did not stay idle. He placed them on Li Sumei's scorching body, beginning to knead and explore every inch... Her massive E-cup breasts were white as snow but burned hot like freshly steamed buns. Her sweet-colored nipples were strangely hard and fought against his hand.
He tried to arouse her, hoping her natural lubrication would aid in penetration. But when he tried to send his index finger into her love groove...
"Ouch!" He cried out softly and yanked his finger back immediately! His fingertip was red, as if scalded by boiling oil!
"Damn it! The Yin Fire has gathered at the Jade Gate so intensely it's this hot!?"
...Wang Cheng changed his plan immediately. "Little girl... stop for a moment. I have something to tell you."
Liu Yuexin looked up. Her lips were slightly swollen, and clear saliva coated them enticingly.
"I cannot penetrate Miss Li directly; the Yin Fire is too intense... The only way to treat her is to inject the 'Yang Medicine' onto her directly until the Yin Fire is suppressed."
"Then... what should we do?"
"You must bring me close to the edge... and I will handle the rest!"
Liu Yuexin accepted the order. She returned to her duty with vigor. This time, she was faster and rougher, following her awakened instincts... Her tongue flicked like a serpent, and her mouth sucked violently, creating lewd slurp... slurp... noises.
"I... I'm close!" Wang Cheng growled low.
He pushed her away, then quickly turned to Li Sumei's body. He spread her hips slightly, aimed his Yang Dragon at the scorching entrance of her heaven, and released a stream of white, turbid Yang energy with full force!
Hiss!
A sound erupted like water splashing onto hot iron!
Wang Cheng stood panting slightly, but Li Sumei's face remained flushed and tormented.
"Damn it... This isn't enough! It's like throwing a cup of water on a bonfire!" He complained in frustration. "We need to do it again! And much more of it!"
He turned to look at the kneeling Liu Yuexin with burning eyes. "Little girl... take off your clothes... We need a more effective method!"
Liu Yuexin complied instantly. He pressed her body onto the floor beside the bed before thrusting his manhood into her violently. "I need your Yin energy to help stimulate me!"
He pounded his giant shaft in and out of Liu Yuexin's beautiful pink pussy like a madman. The sound of flesh slapping rang out—Pap! Pap! Pap!—mixed with her breathless moans. "Ah! Ah! Uncle! I... I feel it too..."
When he felt he was reaching the peak again, he withdrew from her body and turned to unleash onto Li Sumei's Heavenly Gate once more!
"Still not enough!" He roared in annoyance. "We need something more intense!"
He propped the unconscious Li Sumei up against the headboard. Then he turned to order Liu Yuexin. "Little girl, come here!"
He pulled her to stand right in front of Li Sumei, positioning her legs slightly apart, clearly revealing her soaking wet love groove.
"Uncle... what are you going to do?"
He didn't answer but did something she didn't expect! He inserted his giant dragon into Li Sumei's unresponsive mouth. Simultaneously, he buried his face in Liu Yuexin's crotch standing before him!
"Ahhhhhhh!"
Liu Yuexin screamed at the top of her lungs! The image of Uncle voraciously servicing her with his mouth while his manhood was in another woman's mouth was incredibly shameful yet violently arousing! His tongue sucked and flicked her pearl wildly, while his hips thrust in and out of Li Sumei's mouth rhythmically!
"Ah... Uncle... I... I'm going to cum... Ahhh!"
At the moment Liu Yuexin's body convulsed in climax, Wang Cheng roared and released the third wave of Yang energy down Li Sumei's throat completely!
He withdrew, panting heavily, before feigning back pain.
"Ouch... my waist... I really am old... Little girl... you get on top this time. I have no strength left."
Liu Yuexin, fresh from her climax, obeyed docilely. He lay on his back on the bed beside Li Sumei. She quickly straddled him, guiding the still-erect dragon to her own entrance, and slowly lowered herself.
"Hsssssssss!"
She began to ride him heatedly, hoping to milk the Yang energy for him again. But this time, it seemed Wang Cheng couldn't control himself!
"I... I'm coming! Little girl! Get up, quick!"
"Eh!?" Liu Yuexin, lost in pleasure, froze. She tried to get up, but the sensation coursing through her body made her too slow!
"Ahhhhhhh!"
Wang Cheng roared, convulsing and releasing the warm stream into her body completely!
"Haa... Haa... Uncle... Uncle couldn't hold it..." he said huskily.
Liu Yuexin blushed, but instead of being shocked, she immediately jumped off him! She quickly squatted over the face of the still-unconscious Li Sumei!
"Uncle! Hurry! Don't let the medicine go to waste!"
Wang Cheng's eyes widened... This girl truly knew his heart! He didn't wait, inserting his fingers into her love groove, scooping out the mixture of his white seed and her juices, and then carefully smeared it into Li Sumei's mouth!
...After Wang Cheng swallowed a Stamina Recovery Pill, his vigor returned in the blink of an eye!
"Alright... judging by her color, we are close to success. Let's continue treating her!" he said with a husky voice, his eyes full of determination. "This time... we pull it out by the roots!"
He looked at Li Sumei's beautiful body on the bed. Although her temperature had dropped, faint Yin Fire still radiated from her. He wasted no more time. He flipped her limp body over onto her stomach, pulling her hips high into a kneeling position, fully exposing her large, round buttocks and the flushed Heavenly Gate. Her beautiful face was buried in the soft silk pillow.
He knelt on the bed behind her, pressing his fully erect dragon against her crotch, and began to rub it back and forth slowly! The flared head of the dragon rubbed against the plump petals. The heat from her body sent shivers through him. He rubbed it up and down... from the soft mound to the entrance, the deliberate friction creating a lewd Squelch... Squelch... sound.
Liu Yuexin, sitting by the bed catching her breath, watched the scene with glazed eyes... The image of Uncle about to "treat" another woman with such a savage pose reignited the primal fire within her! The heat in her loins made it impossible to sit still!
She slowly crawled onto the bed... but not towards Wang Cheng. She crawled to the other side of Li Sumei!
She lay on her back in front of Li Sumei, then lifted her legs over the unconscious girl's shoulders, positioning Li Sumei's face right between her legs!
"U... Uncle... I... Let me... 'help' with the effort," she said with a trembling voice.
Wang Cheng glanced at her bold action with satisfied eyes before chuckling in his throat. "As you wish... The more the Yin energy is agitated, the better the treatment."
Permission granted, Liu Yuexin didn't wait! She began to grind her hips against Li Sumei's sleeping face heatedly! She used one hand to hold Miss Li's head tight, rubbing her sensitive pearl against the girl's lips and nose wildly!
"Ahhh... Hsss... Miss Li... Ahhh... Good... So good..."
The scene was breathtaking! On one side, the Uncle was preparing to ram his dragon into the back door (or the now accessible front); on the other, his assistant was pleasuring herself with the patient's face!
Wang Cheng couldn't hold back anymore! He stopped rubbing the outside and drove the head of the dragon into Li Sumei's scorching love groove all the way to the hilt in one go!
"Ahhhhhhhhhhhhh!"
Liu Yuexin's scream of pleasure harmonized perfectly with Wang Cheng's roar!
Liu Yuexin's body convulsed violently, her love juices flooding over Li Sumei's face... And at that same moment, Wang Cheng released the stream of Yang energy for the... tenth time! He injected it into Li Sumei's body with full force, draining every last drop!
Whoooosh!
This time... a different reaction occurred! Faint white steam rose from Li Sumei's body like vapor! Her body, which had been trembling violently, slowly calmed down...
Her shivering stopped completely... Her flushed face began to return to a normal color... Her breathing, once ragged and hot, became calm and steady... The body temperature that had been like a blazing fire slowly cooled down to that of a normal fever!
"Success... It's a success..." Wang Cheng muttered, exhausted. He collapsed to sit beside the bed, drenched in sweat.
He looked at his handiwork... Li Sumei's beautiful body was now covered in the mess of his white seed and Liu Yuexin's fluids... not to mention the red marks from his gripping...
He turned to order Liu Yuexin, who lay exhausted just the same.
"Little girl... I leave it to you... clean this up properly... I need to go down and talk to Patriarch Li first. If he walked in and saw his daughter in this state right now... he'd probably drop dead from a heart attack."
