Sun Donghao’s words sparked an idea in Wang Zhuo. Gu Meixue's unborn baby was a boy—but what about Nan Bing’s? Was hers a boy or a girl?

In ancient times, one could only see the sex of a child after its birth, when the fruit had ripened and fallen. In modern medicine, however, one could usually determine the sex of the unborn baby around the sixth month of pregnancy using diagnostic equipment like B-ultrasound, which allows for a form of visual penetration. Still, the results from a B-ultrasound are not always one hundred percent accurate; this largely depends on the skill of the operator and the individual characteristics of the baby. But for Wang Zhuo, there was no such trouble. He possessed the powerful ability of clairvoyance, allowing him to discern the chromosomal makeup of this new life from the very moment the sperm and egg united.

Every cell in the human body contains twenty-three pairs of chromosomes: twenty-two pairs of autosomes and one pair of sex chromosomes. Females possess two X chromosomes (XX), while males possess one X and one Y chromosome (XY). As a clinical medicine student, a distinguished expert in pharmaceutical research, and an awakened psychic, Wang Zhuo had long studied concepts like chromosomes and DNA. Though his understanding hadn't yet reached the level of instantaneous, intuitive application, his grasp of existing knowledge was quite comprehensive.

The clairvoyant eye once again penetrated Nan Bing's uterus, where a tiny life was growing and developing. Wang Zhuo effortlessly located the nucleus within one of the cells, magnifying and bringing the hidden chromosomes into sharp view before him.

If anyone else could share Wang Zhuo’s vision at that moment, they would be stunned to find a massive, three-dimensional holographic image superimposed on the revolving dining table in the private room. It was like the high-tech animation from a sci-fi movie—vividly colored and intricately structured. Many people wouldn't understand what they were seeing, but a specialist in genetics research would instantly gasp, recognizing it as a karyotype!

Chromosomes are composed of DNA and protein, residing within the cell nucleus. Using a high-power electron microscope, one can analyze their various characteristics to perform important tasks like paternity testing and sex determination.

For Wang Zhuo, sex determination was trivially simple. He immediately located the pair of sex chromosomes among the twenty-three pairs. To his regret, it was a pair consisting of one X and one Y chromosome—meaning the baby was a boy. Donghao was going to be disappointed. Once the sex chromosomes are formed, they cannot change; there is no phenomenon where they mutate into the other sex during development. The same holds true for the other chromosomes, so the general blueprint for what this unborn child will look like is largely set in the womb.

Of course, postnatal influences still exist—one might eat too much and become obese, or poor economic conditions might stunt growth, causing someone destined to be 1.9 meters tall to only reach 1.7 meters. However, many hereditary diseases are confirmed the moment the gene is formed.

Modern medicine is highly advanced, yet deciphering the function of every gene segment within the DNA remains an extremely tedious and complex task. Although scientists from multiple countries have completed the human genome map, there is still a long road ahead to fully understand and, eventually, modify it. With nothing pressing to do, after confirming the future baby's sex, Wang Zhuo decided to check for several familiar hereditary conditions, such as polydactyly, congenital deafness/mute syndrome, hemophilia, and albinism.

Fortunately, this baby showed no predisposition to these illnesses. Otherwise, Wang Zhuo might have felt utterly dejected; discovering a hereditary disease in an unborn child yet being unable to prevent its birth would be a truly agonizing situation.

"I'm going to ensure she receives the most advanced education in the world, even if we have to emigrate."

As Donghao proudly delivered his declaration of fatherhood, Wang Zhuo smiled faintly and proceeded to clairvoyantly scan the DNA sequence chain of the boastful fellow, projecting the image onto his own sight, ostensibly for a paternity test between him and his unborn son.

Wang Zhuo had enjoyed paternity testing for a while when he first mastered the skill, even testing himself and his father. In fact, just an hour ago, he had quietly performed one for his father and Gu Meixue's baby boy to confirm their blood relationship.

In the history of world cultural development, tracing back to ancient times, Chinese people had the method of blood-dripping identification, though that method was unreliable.

In the contemporary era, routine paternity tests yield results in seven days, with expedited tests taking as little as two. This is a scientific, legally valid method of verification widely accepted across the board.

But for Wang Zhuo, a paternity test took a mere three minutes. A routine test requires comparing key genetic points between two samples, whereas he only needed to overlay the images of the entire chain via projection; the extent of any difference became immediately apparent!

This didn't require him to project the paternal image in his left eye and the offspring’s in his right, playing a game of "cross-eyed" until they overlapped. The entire process occurred within his brain.

Otherwise, if he were simultaneously chatting with Donghao and his eyes suddenly crossed, wouldn't it terrify Sun Donghao? When he said three minutes, it meant exactly three minutes. He used one minute to adjust the angle and size of the two gene chains, another minute to overlap them and correct minute details, and the third minute for analysis and judgment...

The result arrived. Wang Zhuo, who was chewing a hazelnut kernel, suddenly cracked it, his pupils instantly dilating twofold!

Donghao's gene chain showed significant discrepancies with the baby's. The child’s father was someone else!

"Wang Zhuo, what's wrong?"

Noticing his sudden stiffening expression, Donghao asked with concern.

"Ah? Oh!" Wang Zhuo snapped back to reality and casually covered up, "I just remembered something I forgot to handle. You guys sit tight; I'm stepping out to make a call!"

He tasted something coppery and salty—he had bitten his inner cheek, drawing a bit of blood. Standing in the hallway, Wang Zhuo frowned, momentarily unsure how to deal with this.

The more he thought about it, the angrier he became. Back when Haozi started dating Nan Bing, everyone had some reservations, but Haozi was captivated by her beauty and gentle demeanor. Moreover, Nan Bing had presented herself quite well publicly, so she was gradually accepted. To think that after two years of dating, when things were reaching the point of marriage, this sort of thing would surface—this wasn't just being cuckolded; they were handing him a free son! It was too much!

If he had known this day would come, he should have broken them up back then! Wang Zhuo felt a pang of self-reproach. He had even sent Feilong to investigate Nan Bing's background, knowing she had a less-than-honorable past. But seeing her improved conduct afterward, he hadn't followed up on the observation, and look where it led—trouble finally erupted!

He pursed his lips and took out his phone to call Feilong.

As soon as Feilong answered, he boomed, "What is it, Boss? I'm driving to the restaurant now. We're not going the same way."

"I need to ask you something," Wang Zhuo whispered, using his clairvoyance to check on Haozi and Nan Bing inside the room. "Are you still in contact with that model, Lu Yao?"

"Yeah, why? Are you interested, Boss?" Feilong snickered. "Eight hundred for a quickie, twelve hundred for the night. Do you want us to be brothers-in-law?"

"Get lost, I’m being serious," Wang Zhuo commanded. "Isn't she a model? Why are you talking about quickies and overnight stays? Did she go 'underground'?"

"It's not really 'underground.' She calls it part-time work," Feilong replied. "Why are you suddenly asking about her? What's the situation?"

Wang Zhuo countered without answering, "Where are you now?" Feilong said, "Almost there, maybe fifteen minutes away."

Wang Zhuo gave low instructions, "When you arrive, wait outside. If anyone calls asking for you, tell them you're on the way. Wait for my word—understand?"

"Got it, got it." Feilong agreed readily, then asked quietly, "What's the big secret, Boss?"

"I'll tell you later!" Wang Zhuo decisively ended the call.

Reaching the end of the hallway, he called Siyuan and gave her an urgent task: "I'm going to give you a number. Memorize it, and then immediately send me the communication records for the last week. I need it urgently."

The little genius witch was adept at such tasks. In less than a minute, she reported Donghao's communication logs.

Wang Zhuo immediately located the phone number with the most frequent text exchanges. This number differed from Haozi's only by the final digit, so it had to be Nan Bing’s number.

"Check this number. I need the call detail records for the last two months, plus the base station location logs. Send the file to my phone using that software."

The quality Wang Zhuo appreciated most about Siyuan was that she always executed a request immediately, never wasting time asking why. In under another minute, Nan Bing's communication records arrived.

"These records are wrong," Wang Zhuo judged immediately upon seeing the call detail log. Nan Bing must have more than one phone number, as this specific number showed no frequent calls to anyone other than Donghao.

Quickly using his clairvoyance to penetrate the ten-plus meters of walls and furnishings, he searched Nan Bing's personal belongings and indeed found a SIM card tucked into a compartment of her makeup bag.

Frowning, he asked Siyuan over the phone, "Using the four rows of numbers printed on a mobile SIM card, can you figure out its phone number?"

"I can only confirm the first four digits, like 1380," Siyuan replied. "That's the IMSI number assigned by the International Telecommunication Union to global carriers. It has no correlation with the last seven digits of the actual phone number. If you're not in a rush, I can crack the database for you, but it will take some time."

"Is there no shortcut?" Wang Zhuo scratched his head.

Siyuan paused, then quickly responded into the phone, "Knowing other numbers used by the phone that utilized this card would work. I can use that number to find the corresponding mobile license registration number from the carrier's database, and then reverse-engineer to find the other associated card numbers used by that phone—that's much faster."

This was the method the police used for investigations. Wang Zhuo snapped his fingers—Siyuan certainly had talent. He decided he would reward her handsomely when he returned!
