Lu Cheng's words were still watertight.
He openly explained what they had just been doing.
And subtly hinted at how ill-timed and lacking in foresight Qin Yu's appearance was at that moment.
But Qin Yu couldn't care less; he only believed what he saw and heard!
Acupuncture technique?
Although he had only learned martial arts from his master, he had a rudimentary understanding of medicine.
He had never heard of an acupuncture technique that would be learned like this!
Qin Yu's eyes were bloodshot as he stared intently at the two figures in the room, his voice twisted and distorted by disbelief and extreme anger:
"Studying... studying acupuncture techniques?!"
"Do you take me for a three-year-old child? Or a fool?"
"In broad daylight! A man and a woman alone! Hugging and embracing! You call this studying acupuncture techniques?"
He still clung to a last, unrealistic hope, casting a pleading gaze at Luo Qingyan, who was embraced by Lu Cheng, expecting his Senior Sister to tell him it was all fake.
Lu Cheng heard Qin Yu's roar, full of righteousness and fantasies of a hero saving the beauty, and a deeply mocking curve appeared at the corner of his mouth.
He seemed to find this kind of "death throes" drama somewhat amusing, and somewhat... impatient.
Lu Cheng lowered his head and whispered in Luo Qingyan's ear in a tone only she could hear, full of ambiguity and teasing:
"It seems... your Junior Brother has a lot of opinions about our 'teaching' methods."
Alas, who made him an elder now?
He still decided to deliver a few more blows to this presumptuous Junior Brother.
Facing Qin Yu, who was trembling with anger at the doorway, he spoke slowly and methodically, in a patient and instructive tone:
"Hehe... Junior Brother Qin Yu, it seems you're not a medical student, are you?"
"I think you might have some... hmm... rather one-sided misunderstandings about the word'study'."
"Some profound medical principles, especially those acupuncture techniques involving the circulation of qi and blood in the human body and the harmony of yin and yang, indeed... require some rather close, rather in-depth guidance methods to allow learners to grasp their essence and mysteries more quickly and deeply."
"It can only be understood intuitively, not explained in words, understand?"
"Of course," Lu Cheng's tone suddenly shifted, now carrying an undisguised admiration and self-satisfaction as he reached out and ambiguously stroked Luo Qingyan's soft, beautiful hair.
"Qingyan is naturally intelligent, highly perceptive, and learns things very quickly."
His words were so grand and righteous.
But every single word in his speech was full of strong hints and... blatant showing off!
This made Luo Qingyan subconsciously and even more shyly hit Lu Cheng's chest a few times with her delicate fists, then snuggled deeper into his embrace.
Lu Cheng looked at the infinitely shy and endearing appearance of the beauty in his arms, feeling even more pleased.
He chuckled contentedly, then his gaze turned back to Qin Yu at the doorway, who was almost fuming with anger but couldn't find anything to retort.
In a matter-of-fact tone, filled with undisguised showing off, he slowly announced:
"And, Junior Brother Qin Yu, you've just come down from the mountain, so there are some things you might... not be very clear about yet."
He paused, a smile of a triumphant victor and one in control of everything curving his lips, and he said, word by word:
"It's my fault, I forgot to properly introduce myself to you earlier."
"My name is Lu Cheng."
"I am Qingyan's boyfriend."
"In other words, if we go by your sect's hierarchy..."
"You should... call me Brother-in-law."
"So, Junior Brother,"
Lu Cheng's eyes suddenly became somewhat cold, and his tone carried a hint of warning.
"From now on, please be more respectful of the private matters between your Senior Sister and me."
"After all, if you interrupt our 'teaching,' your Senior Sister... might not be happy, you know?"
Bro... Brother-in-law?!
Upon hearing these two words, like a bolt from the blue!
And Lu Cheng's words, full of hints, threats, and declarations of ownership!
Qin Yu's mind, in that instant, went completely blank!
All the anger, jealousy, unwillingness, and that last, unrealistic hope!
At this moment, they were all mercilessly crushed by Lu Cheng's understated yet incredibly cruel words.
Not even a speck remained!
Master didn't even tell me... Senior Sister has a boyfriend?
Wasn't I supposed to procreate with Senior Sister?
Didn't he say Senior Sister was entrusted to my "care"?
What am I caring for?
Am I supposed to go buy them condoms?
He only felt a wave of blackness before his eyes; he had never seen his parents since childhood, and his only master was dead.
Now, out of nowhere, he had an extra Brother-in-law.
Who could bear this?
He dared not think further!
This world down the mountain, he couldn't understand it; no, not just the world, he couldn't understand his Senior Sister either.
One moment she was like a fairy descended, the next she was shyly nestled in someone else's arms.
But how could he be reconciled to such a beautiful Senior Sister?
This was simply... the most beautiful woman he had ever seen in his life!
Even the celebrities on TV couldn't compare to his fairy Senior Sister!
He raised his head, his eyes bloodshot, glaring at the man who had stolen his Senior Sister.
He was confident that Lu Cheng would definitely not be able to defeat him; even if Lu Cheng looked big, he would win within one move!
Since a verbal fight wouldn't work, should he try a physical one?
Just as Qin Yu's emotions were about to completely erupt, or rather, he was preparing to rush forward and fight Lu Cheng regardless of the consequences—
Lu Cheng, however, was already too lazy to waste another word on him.
He looked at Qin Yu at the doorway, whose nostrils were flaring and whose face was flushed, and a cruel sneer appeared at the corner of his mouth.
Then, with a somewhat polite yet undeniably firm gesture, he slammed the open door shut with a "bang"!
Completely and mercilessly shutting out Qin Yu's distorted face, and his roar, full of unwillingness and anger, that was about to burst forth!
Inside the room, only Lu Cheng's clear voice, tinged with a hint of coldness and impatience, faintly transmitted through the door panel:
"Junior Brother Qin Yu, your Senior Sister needs to rest now."
"She also needs a quiet environment to properly consolidate the knowledge she learned today."
"I won't see you out."
"Whatever it is, let's talk about it tomorrow!"
