There was a method of fraud where criminals could technologically manipulate the caller ID to display whatever number they wished, provided the recipient's phone had caller ID enabled.

However, this scam had one critical flaw that made it easy to counter: if you ended the call and dialed the number back, you wouldn't reach the impersonator, but rather the legitimate owner of the displayed number.

This meant that when Wang Zhuo spoofed the underground lover's number to call Nan Bing, the caller ID successfully tricked her into thinking it was that man calling. But if Nan Bing called the number back from her mobile, it wouldn't connect to Wang Zhuo's phone; it would connect to the actual man.

Wang Zhuo was exploiting this sleight of hand. So, to prevent his deception from being exposed, he acted first. After Nan Bing left, just as she was about to take out her phone to call, he beat her to it and spoofed that same number again, dialing into her mobile.

With the aid of his X-ray vision, his little trick worked flawlessly. Thus, as soon as Nan Bing pulled out her phone, it vibrated gently. She glanced at the caller ID, suspected nothing, and answered directly.

“Hello?” she murmured, a hint of complaint in her tone. “Didn’t we agree yesterday? I have dinner plans with his friends at this time, so it’s inconvenient to talk to you. Besides, why are you calling this number again? What if I’m near him? Should I pick up or not?” The person hearing these words was not her clandestine lover, but Sun Donghao and Wang Zhuo, who were barely ten meters away from her!

“Hello? Hello?” Seeing no response, Nan Bing persuaded with mounting agitation, “Donnie, I’m not blaming you. Haven’t I snuck out to call you back? Say something?”

“Hello? Hello?” Still no sound, Nan Bing couldn’t tell if the connection was failing or if the other party was simply refusing to speak. She finally conceded, “Forget it, I have to get back to socializing. If you can hear me, just wait for me; see you at the usual spot tonight.”

The call ended. Wang Zhuo quietly put away his phone. Nan Bing’s words had revealed a wealth of information, enough to confirm her two-timing life.

Sun Donghao’s face cycled through colors. He never imagined that the fiancée he was about to marry—and who was expecting his child—had an underground boyfriend outside their relationship, and that their affair was still intimate and hadn't ceased despite her impending marriage. Did this mean he was being played like a fool by both of them?

The thought that the moment he married, he would definitely be saddled with a cuckold’s hat, and that the woman he loved would still occasionally lie to him to spend nights pleasuring another man, made Sun Donghao clench his jaw, wishing he could tear that detestable man to shreds.

“Shall I call everyone and tell them not to come?” Wang Zhuo suggested tentatively.

Sun Donghao nodded slightly. With such a massive issue surfacing, there was no mood for a gathering. Moreover, they didn’t know how things would unfold next; how could he announce his wedding now?

Just then, Nan Bing returned from a trip to the restroom after washing her hands. Wang Zhuo, while calling Cheng Gang, brushed past her.

After informing everyone in the hallway, Wang Zhuo used his X-ray vision to look into the private room. As expected, Sun Donghao was confronting Nan Bing, questioning her actions.

It was still some time before the peak dining hour, so Wang Zhuo casually found an empty private room and sat down, watching the ensuing confrontation with cold detachment.

At first, Nan Bing vehemently denied everything. Only when Sun Donghao mentioned the man’s phone number did her denial shift into sophistry.

“Sun Donghao, saying these things truly chills me to the bone. I’m about to bear your child, and you suspect me!” Nan Bing’s acting skills weren’t insignificant; her years as a print model hadn't been for nothing. “You’ve said so many nonsensical things; I’ll ask you just one thing: What proof do you have?”

“Proof?” Sun Donghao gave a cold laugh, then paused slightly. Right, what proof did he have? He had unconditionally believed Wang Zhuo and immediately accepted his claims, but he had forgotten to ask Wang Zhuo how he discovered this matter!

After all, he was a top student from a prestigious university, and Sun Donghao’s adaptability was strong. He immediately retorted, “Then let me tell you plainly: That call you just took in the hallway wasn't from some ‘Donnie.’ It was from me. You probably didn't expect that the person who heard you say ‘see you at the usual spot tonight’ wasn't him, but me!”

Nan Bing’s expression instantly froze. Sun Donghao’s sudden statement caught her completely off guard, leaving her momentarily unsure how to react.

It was at that precise moment that Sun Donghao’s phone, lying on the table, vibrated a few times. The screen displayed a text message from Wang Zhuo—the timely ammunition provided by Wang Zhuo had arrived.

Sun Donghao picked it up. The content was brief: The SIM card is hidden in the lining of her cosmetic bag.

He snatched Nan Bing’s handbag with sudden force and quickly retrieved the cosmetic bag from inside. Nan Bing’s expression shifted instantly, and she lunged to snatch it back. Her struggle wasn’t meaningless; she wanted to keep the bargaining chip in her hands, which at least gave her some initiative. If she could manage to keep Sun Donghao from getting that card, it would be even more advantageous.

But desperation makes even the meek aggressive. Although Sun Donghao was merely a scholar, the strength that erupted from his fury was not to be underestimated. He swung his arms, shaking off Nan Bing’s tugging, and then brutally tore open the cosmetic bag against the table. With a whoosh, various tube-shaped cosmetics scattered across the table.

Normally, Sun Donghao would never be so reckless, as such rough handling could lead to irreparable consequences. But Nan Bing’s actions had disappointed him too profoundly, and her hypocritical justifications were especially heartbreaking. With a clatter, a pale red SIM card fell onto the table. Sun Donghao’s fingers trembled slightly from emotion as he picked it up, held it aloft, and coldly said to Nan Bing, “The last four digits of this card are 1113. Am I correct?”

“You—you actually hired a private investigator to check on me?!” Nan Bing’s eyes widened in outrage, pointing directly at his nose. “Sun Donghao, you actually distrust me that much!”

“No, I did trust you, but you betrayed that trust,” Sun Donghao spoke, his emotions turbulent, his lips trembling. “If Wang Zhuo hadn’t told me, I might have been deceived by you for who knows how long!”

“Wang Zhuo?!” Nan Bing showed a flicker of surprise, then sneered, “Why is he interfering? He only helped you make some money; does he think he can meddle in other people’s relationships now?”

Sun Donghao snorted. While he felt there was some truth to Nan Bing’s words, he wasn't about to agree with her viewpoint. “Who told me is irrelevant. What matters is that you deceived my feelings, and you still refuse to admit it now.” Just as Nan Bing was about to speak, the room door clicked open—Wang Zhuo had pressed down the handle and walked in.

Nan Bing immediately stared him down without yielding an inch. So what if he was the Little Tyrant of Jiangzhou? Go on, hit me then!

Wang Zhuo had been sitting alone in a private room nearby. Although he couldn't hear their conversation, he could understand everything they were saying through the tone-reading ability of his X-ray vision.

It was only when he heard Nan Bing accuse him of meddling that he couldn't help but return.

Faced with Nan Bing’s stare, he merely gave her a cold look, sat down in a chair, tossed a small piece of cardstock onto the table, flicked it with his finger, and sent it sliding in front of Sun Donghao.

“I calculated it. It’s not even certain that the child in her belly is yours.”

Sun Donghao’s brow furrowed instantly. He grabbed the cardstock and saw it was a page torn from the monthly calendar provided to diners at this restaurant, showing last month’s dates. Wang Zhuo had circled a few spots and added marked symbols.

However, he couldn't quite decipher them.

“Wang Zhuo, is it fun for you to try and sow discord between me and Haozi?” Nan Bing asked coldly.

Wang Zhuo completely ignored her. He took out his phone, dialed a number, and upon connection, asked, “How is the investigation going?”

Siyuan immediately replied, “Almost done. We’ve secured surveillance screenshots for two of the days.”

“Just send them directly to Haozi’s phone; you know his number,” Wang Zhuo instructed calmly. “Make sure the screenshots are clear. Some people don't seem inclined to admit fault.”

“Got it, sending immediately.” The moment Wang Zhuo hung up, Sun Donghao’s phone rang—it was an attachment message from an unknown sender.

“I’ve looked it over. Five and a half weeks ago, the calls made by 1113 were the most frequent, and she often appeared in a less bustling area of Dongjiang District,” Wang Zhuo told Sun Donghao. “Take a look at the email; seeing is believing.”

Sun Donghao opened the email. It contained several screenshots from security cameras, clearly marked with timestamps. These screenshots were from a budget hotel, clearly showing Nan Bing registering in with a man and then leaving.

Indeed, seeing was believing. Upon viewing the screenshots, Sun Donghao’s expression shook, and he felt all his convictions crumble in that instant. The woman who constantly professed her love for him, the delicate woman who asked how he would reward her if she gave him a son, had actually gone to a hotel with another man behind his back!

Recalculating the timeline, it matched what Wang Zhuo had said. During that period, he had indeed returned to his hometown for a quick three-day trip. Due to travel fatigue, he had agreed when Nan Bing said she didn't want to accompany him. He never expected she would spend three consecutive days intimately involved with another man. Looking at it this way, who the father of her child truly was... that was truly uncertain!

“Do you have anything left to argue with?” Sun Donghao listlessly pushed his phone toward Nan Bing for her to see.

With the matter exposed, Nan Bing knew that saying anything more was useless. She shot up suddenly, not bothering to collect the items scattered on the table. Grabbing her purse, she strode toward the door.

Bang!

She slammed the private room door shut with such force that the air inside the entire room vibrated.
