The so-called Day of Yin and Yang referred to the rare date when the lunar and solar calendars aligned.
It was said that if a man of pure yang married a woman of pure yin on this day, heaven and earth would unite, and the couple would enjoy a lifetime of harmony and prosperity.
Of course, Chen Xin'an didn't believe a single word of that superstitious nonsense.
Suppressing a yawn, he looked at the old madam and said lazily, "Grandma, seriously? In this day and age, you still believe in stuff like that?"
"I don't," the old madam replied with a warm smile.
Her answer left Chen Xin'an completely speechless.
So… she was teasing him?
If she didn't believe it, why drag him all the way from Qingniu Mountain, make him marry her granddaughter, and turn him into a live-in son-in-law?
Eighty years old and still playing games like this—what a lively old lady.
Sensing his discontent, the old madam smiled again. "But I do believe in fate. You are Xiruo's fate—and only you can save her."
Fate?Only I can save her? What's that supposed to mean?
Even Ning Xiruo stared at her grandmother, wide-eyed and confused.
The old madam gave Chen Xin'an a knowing smile and even winked, as if daring him to guess what she meant.
Trying to test me, huh?
Chen Xin'an smirked, turned to Ning Xiruo, and said, "You're sick."
Her eyes widened in outrage. "You're the one who's sick! Your whole family's sick!"
Chen Xin'an snorted. "Your sclera has red patches, your complexion's dull, your fingertips are calloused, and your nails are pale—classic signs of poor circulation and blood deficiency.
You walk unsteadily, your movements lack strength, your posture leans forward, and you subconsciously protect your abdomen with your left hand.
Plus, you're breaking into cold sweat while getting goosebumps at the same time. I'd say it's a case of uterine cold."
Ning Xiruo froze in shock.How the hell did he know about that?
The old madam's smile deepened. "As expected of the Immortal Doctor's disciple. I knew I wasn't wrong to make you my grandson-in-law."
Oh, come on, Grandma! That's going too far!
Chen Xin'an frowned and said irritably, "Nine out of ten women have uterine cold. It's not a big deal.
A few herbal prescriptions, taken daily for a month, and she'll be fine. No need to marry me off for that."
Ning Xiruo rolled her eyes. "Grandma, seriously? It's not even a real illness. Any hospital could treat it.
Why do we have to rely on him? And marry him, of all things? Isn't that completely unnecessary?"
The old madam shook her head, her tone turning grave.
"For an ordinary woman, yes. But for a pure yin woman, uterine cold isn't a minor ailment—it's fatal.
No medicine can cure it. Only union with a man of pure yang can sustain her life.
I was also a pure yin woman. That's why I married your grandfather."
Both Chen Xin'an and Ning Xiruo were stunned.
Even Chen Xin'an could tell from her pulse and complexion that she wasn't exaggerating—she was telling the truth.
Then a thought struck him. "Old madam, when did your husband pass away?"
"Oh, that was a long time ago," she said after thinking for a moment. "He was about thirty-seven or thirty-eight. Not long after I gave birth to my youngest son, his yang energy was completely drained… and he left us."
Damn!
So her husband died from being sucked dry?
What is this—some kind of black widow situation?
Marrying a woman like that was basically slapping a death talisman on your forehead!
"Grandma, I can't do this," Chen Xin'an said sincerely. "I don't think I'm good enough for your granddaughter. Please, find her someone else."
The old madam chuckled. "Child, there's no need to be afraid. Your master trained you in both medicine and martial arts since childhood for a reason.
Your body contains endless yang energy—far beyond that of ordinary men.
You and Xiruo are the perfect match. Together, you'll balance yin and yang, strengthen each other, and one day have many children and a long, blessed life."
Yeah, right.
Me, having a house full of kids with her?She doesn't even look like she could handle one!
Seeing the disdain in his eyes, Ning Xiruo's face flushed bright red—but not from shyness. She clenched her teeth and snapped, "What are you staring at? Keep looking, and I'll gouge your eyes out!"
Chen Xin'an turned away with a shrug.
Not much to look at anyway.
The old madam smiled as if nothing was wrong. "You two have such wonderful chemistry! I'm very satisfied with this match.
Tomorrow, you'll get your marriage license. The wedding will be on August eighth. It's settled."
Chemistry?
We're one insult away from stabbing each other, and you call that chemistry?
Before either of them could object, the old madam continued, "Now, go have dinner. Meet the rest of the family. You're one household from now on."
Chen Xin'an sighed helplessly and followed her orders. He had just reached the stairs when Ning Xiruo called from behind, "Wait!"
He turned around, half-lidded eyes narrowing. "What now?"
Biting her lip, cheeks flushed, she said, "I know you don't want this—and neither do I.
But no matter what, we have to go through with the wedding. Even if it's just for show, we need to make it convincing. I don't want Grandma to be disappointed."
Chen Xin'an scoffed. "Why bother? What's the point?"
She glared at him. "You think I want to marry you? I'm doing this to make Grandma happy—to help her recover faster!"
He didn't reply. He could tell the old madam's health was failing.
Her energy was fading fast, and even speaking for a few minutes left her breathless.
He might be skilled in medicine, but against the natural course of life and death, even he was powerless.
"…Alright," he said finally, nodding.
He wasn't heartless.
If granting an old woman's last wish cost him nothing, he had no reason to refuse.
As for that talk about "balancing yin and yang"—that was never going to happen anyway.
"Thank you," Ning Xiruo murmured, dabbing the corner of her eyes before walking downstairs.
She actually thanked me?
That was… unexpected.
Scratching his head, Chen Xin'an chuckled and followed after her.
Rich people really lived differently.
The Ning family's dining hall was larger than most people's entire apartments.
Tonight wasn't a formal banquet—just an introduction for the new son-in-law. Still, it was clear the Ning family didn't take him seriously.
None of the four sons had come—only some of their wives and children.
Without the old madam's insistence, probably no one would've bothered to show up at all.
The five grandsons and three granddaughters were mostly there, except for the youngest, Ning Xi, who was still away at university.
A large round table sat over a dozen people, and it still wasn't full.
Leading Chen Xin'an to the main table, Ning Xiruo pointed to a few elegantly dressed women. "This is my eldest aunt, my second aunt, and my fourth aunt. We'll sit here."
Since they had to put on a good show, Chen Xin'an decided to play along. He greeted them politely, "Eldest Aunt, Second Aunt, Fourth Aunt."
The women didn't even glance at him. One of them merely curled her lip and went back to chatting as if he didn't exist.
Ning Xiruo's face darkened, but Chen Xin'an remained completely unfazed.
He greeted everyone with the same calm smile and then sat down without the slightest hint of embarrassment.
