The next afternoon, another important figure related to the imperial family arrived at my mansion—Zhangsun Wuji!
"Old people are cunning, old horses are slick," this saying is indeed true. When Zhangsun Wuji arrived, he didn't mention a single word about his legitimate eldest son Zhangsun Chong causing trouble at the mansion last night.
Instead, with a face full of smiles, he sat in my study and discussed the issue of consanguineous marriage with me~~
"Mister Wu, this morning I went to the Ministry of Revenue and checked the number of mentally challenged children in the Guanzhong region. It is indeed as Mister said, Mister is greatly talented!"
Zhangsun Wuji sat by the table, cupped his hands in a respectful bow towards me, with a genial smile on his face.
"Duke of Zhao, you are too kind. This humble commoner is just a physician. During my medical practice, it's inevitable to encounter parents seeking medical advice for their mentally challenged children. Having seen many, I naturally came to understand." I returned the bow, but inwardly I grumbled continuously, thinking that this old fox was praising me right away, so nothing good would come of it.
"Then, Mister Wu, do you have a method to resolve it?" Zhangsun Wuji continued to look at me with a smile and said.
"Yes, and only one!" I looked at Zhangsun Wuji's face, my tone serious. "That is to prohibit consanguineous marriage. Those with familial ties must also marry only after five degrees of kinship~~"
"As for those who are already married now~~" Zhangsun Wuji seemed to know I would say this and was not in a hurry.
"Nothing can be done, only fate can tell. It's not to say that consanguineous marriage will definitely produce mentally challenged children; it's just that there's a high probability of mentally challenged children appearing, and even physical deformities." I shook my head, indicating there was no solution.
"Alas..." Zhangsun Wuji sighed heavily, then asked again, "Is this respiratory illness also as Mister said, it cannot be eradicated, only suppressed?"
"Yes, it cannot be eradicated~~" I still shook my head. After all, this respiratory illness cannot be eradicated even in later generations, let alone in ancient times.
"Alas..." Zhangsun Wuji sighed heavily again.
"Duke of Zhao, there's no need to worry. This humble commoner knows why the Duke of Zhao asks this. This humble commoner can guarantee with my life that with proper diet and moderate exercise, the respiratory illness can be suppressed. Even if it recurs, it will not endanger life."
I looked at Zhangsun Wuji and slowly said, "Just to add incidentally, marrying too early is also a major contributing factor to contracting respiratory illness~~"
"Then, according to Mister's words, what is the appropriate age for men and women to marry?" Zhangsun Wuji asked, regaining his spirits.
"Men and women can marry at eighteen. Do not marry before this. Even if married, try to avoid pregnancy, because a woman's bodily development is not yet mature before eighteen, and there is a very high probability of dying in childbirth..."
I slowly stated a truth that would be common knowledge in later generations.
"Is what Mister says true!?" Zhangsun Wuji seemed very surprised by my words, with doubt in his voice.
"Indeed. Duke of Zhao, with your high position and great power, you can go to the Ministry of Revenue to verify the ages of mothers who died in childbirth in Chang'an City."
I nodded, and at the same time, said something that no one in this current world had ever said, "This is actually a fertility trap. It seems that early marriage and early childbearing can increase the number of children in a short lifespan and increase the population, but in reality, it's not so. The success rate of childbirth is the most important~~"
I poured myself a cup of water, took a sip, and then continued, "To give an example, a woman marries at twelve and gives birth to her first child at thirteen. But early childbearing will harm her body. In that case, the mother generally won't live long, moreover, there's a possibility of dying in childbirth with the first baby. If the mother's age is postponed to after eighteen, or even after twenty, the success rate of childbirth will greatly increase, and it will also be safer for the mother's life, the probability of difficult childbirth will greatly decrease!"
"Let this old man go to the Ministry of Revenue to verify. If it is truly as Mister said, Mister will be a meritorious official of my Great Tang!" Zhangsun Wuji said thoughtfully, and a moment later, he asked with a smile, "I wonder~~ does Mister have the intention to enter officialdom?"
"As for entering officialdom, let's wait a bit. This humble commoner still wishes to further research medical techniques and invent things useful for the Great Tang~~"
I quickly refused, thinking that his Zhangsun family was also a Hedong aristocratic clan, and I didn't want to get involved with them.
But since I couldn't say these words directly, I could only smooth things over again. "By then, I hope the Duke of Zhao will disregard past grievances and recommend this humble commoner~~"
"Hahahahaha~~" Zhangsun Wuji laughed heartily, then raised a hand and pointed a finger at me. "Wu Xuanjing, ah, I thought you weren't going to mention last night's matter."
"Heh, after all~~ it's a bit awkward~~" I also let out a bitter laugh, thinking that I had beaten the junior the night before, and the senior arrived the next day.
He came without mentioning blame, only discussing state affairs, which gave me a feeling of "a dog biting a hedgehog, nowhere to bite," and it was very uncomfortable.
"Hahahahahahaha! No matter! No matter! Trading a good beating for my son for the prosperity of my Great Tang, it's worth it!"
Zhangsun Wuji was quite generous, standing up with a big laugh, patting my shoulder, then cupped his hands in a bow towards me and said, "If Mister still has any ideas beneficial to the Great Tang, please do not hesitate to give your valuable advice!"
"Duke of Zhao, you exaggerate! I dare not accept such an honor as advice! Everything is for the Great Tang!" I quickly stood up and returned the bow, then said what I had already prepared, "This humble commoner has designed some things recently. I hope the Duke of Zhao will accompany this humble commoner to the study for a look."
When I brought Zhangsun Wuji to the study, I immediately locked the study door, then took out four blueprints from the secret compartment in the bookshelf and spread them on the desk.
Then I explained the contents of the blueprints one by one. Actually, I had held back a bit. This time, what I took out were only blueprints for cement, the curved-shaft plow, steelmaking, and movable type printing.
As for blueprints with obvious military uses such as gunpowder, hand-cannons, cannons, hot air balloons, and telescopes, I didn't take them out. After all, I am just a commoner now, and designing so many military-related items is simply courting death.
After all, "A common man is innocent, but possessing a treasure makes him guilty." One should still listen to the words of the ancients. Moreover, I didn't take out the civilian blueprints either, things like soap, perfume, stir-fried tea, distilled wine, these were what I planned to use to get rich~~
After I finished introducing how these items on the blueprints were manufactured and used, Zhangsun Wuji's eyes, looking at me, immediately burst forth with a sharp gleam as if a lion or tiger had locked onto its prey, but what he said next completely stunned me~~
"Xuanjing, ah..." Zhangsun Wuji stared intently into my eyes, and in a negotiating tone, said, "How about~~ you beat my son up again? And then take out some more designs beneficial to the Great Tang, how about that?"
It's over, Zhangsun Wuji has gone mad...
After seeing off the happily departing Zhangsun Wuji, who was clutching the four blueprints, I returned to the inner residence.
As I stepped into the entrance of the inner residence, I saw my wife sitting peacefully under the willow tree by the lotus pond in the inner residence, doing needlework, with a pair of tender, fair, jade-like bare feet. Looking at my wife's charming yet aloof and beautiful face, her plump yet not cloying delicate body, her long and slender legs yet not lacking in curves, and her delicate and fair jade-like feet, for a moment, I couldn't help but stare blankly~~
Gentle breeze, warm sun, willow leaves gently swaying, flowers fragrant, beautiful woman elegant—this scene was so quiet, beautiful, graceful, and refined, just like a masterpiece of ingenious craftsmanship. I just stood quietly at the inner residence's entrance, watching my wife not far away, unable to bring myself to break this fairyland-like scene.
"Cheeks like fresh lychees, nose like goose fat, gentle and silent, pleasant to behold~~"
Looking at the picturesque beautiful scenery before me, I couldn't help but murmur to myself. Then, thinking of my unbearable body, actually unable to satisfy such a gentle and alluring wife, I couldn't help but beat my chest and stamp my feet, filled with regret. "Alas~~ this hateful body of mine! Hateful cruel heavens!"
With a resigned mood, I quietly exited the inner residence's entrance, turned, and walked towards Zaha's small courtyard. When I arrived at the entrance of Zaha's courtyard, Zaha was inside, telling some jokes to Princess Xiangcheng's two mixed-race children, making the two children laugh so hard they leaned back and forth.
"Zaha, come here for a moment~~" I walked into the courtyard and called out to Zaha, "I have something to ask you!"
"Oh! Yes, master!" Zaha turned his head, saw that I had arrived, and immediately responded.
"You two little fellows, go out and play first. Zaha and I have something to talk about~~" I reached out and stroked the little heads of Princess Xiangcheng's two mixed-race children. "If you want snacks, go to the back kitchen and get them yourselves. If the cook asks, just say I allowed it, go!"
"Okay, master!" "Thank you, master!" The two little fellows happily ran out after I finished speaking.
After watching the two little fellows run out, I sat down by the stone table in Zaha's courtyard, picked up the kettle on the table without any formality, poured myself a cup of water, then pointed to the stone stool opposite me, signaling Zaha to sit down~
"Zaha, are you familiar with this Abu?" After Zaha sat down, I asked, holding the water cup, "You two used to make a living in Pingkang Ward, right?"
"Reporting to master, Zaha once served noble guests with Abu in that underground circle in Pingkang Ward. I dare not deceive master, Abu is extremely skilled at licking cunt for women, and his tongue is very long~~"
Zaha paused in his words, then said with an embarrassed expression, "Moreover, Zaha and Abu were also double penetration partners in Pingkang Ward. Although Zaha doesn't want to admit it, Zaha's thing can't compare to Abu's. Abu's thing is terrifying!"
"Oh? How is it terrifying? Is it even bigger than yours?" My interest was suddenly piqued after hearing Zaha's words.
"No, no, no! Abu's thing is about the same size as Zaha's, but Abu's thing has spherical protrusions; it's not a disease, it's natural. Once, a noble lady was penetrated by Abu only ten times, and she squirted all over the floor~~"
The embarrassed expression on Zaha's face intensified, but he continued to tell me about Abu's past. "And Abu's semen volume is super huge. Noble ladies often sought him out to experience the feeling of having semen applied to their faces. However, Abu was sold also because of this ability."
"What did he do?" I asked curiously.
"That time it wasn't Abu's fault, it was what that noble lady requested. That noble lady requested Abu to ejaculate inside her. Master, you might not know, but the first rule we were required to follow in Pingkang Ward was to satisfy all the guests' requests, provided it didn't endanger their lives. And Abu himself is the kind of simple and honest person. After hearing the request, he didn't overthink it; he directly thrust into that noble lady's Flower Palace entrance and ejaculated~~"
Speaking of this, the expression on Zaha's face had already turned from embarrassment to helplessness. "But because the semen volume was too large, it almost caused a death. That noble lady's belly eventually swelled up as big as a woman who was three months pregnant..."
"Pfft!" I had just picked up the water cup and taken a sip when I was so startled by Zaha's final description that I sprayed out all the water. "Oh my god! This Abu is just like you, both belong to the animal-like type."
"Hehehe~~ Thank you, master, for the praise!" Zaha probably didn't understand what I meant, only replying with a chuckle.
"I'm giving you an important task. Go find Abu in a bit and tell him that tonight I want him to~~"
As I spoke, I put down my teacup and rose to head for Zaha's courtyard gate, preparing to leave. But at that moment, I suddenly had an idea.
I had promised to reward Abu, and the reward, of course, was for him to fuck Li Ying. Rather than let Abu fuck Li Ying alone, why not call Zaha over too, and have them both fuck my wife tonight? After all, in my past life, I always wanted to see my wife double-penetrated by big black cocks, but I never had the chance. Now, in this life, the opportunity was right before my eyes.
So I stopped, turned to Zaha, and said, "You come too. Tonight, you and Abu will serve your Mistress together. But you need to tell Abu the precautions. Don't go and ruin your Mistress. And tonight, I'll allow you to double-penetrate your Mistress, but you must be gentle. Your Mistress's rear chrysanthemum hole has never experienced such big fellows, understand?"
"Yes, Zaha obeys! Zaha and Abu guarantee to serve Lady Ying until she climaxes to incontinence and squirting fluid splashes everywhere!"
Zaha answered loudly.
Alright, tonight, just tonight, my beloved wife Li Ying was going to be double-penetrated by these two black fellows, sandwiched between them. The thought truly made me excited...
