Tonight, my wife was working overtime at the office. I was about to enjoy some alone time playing video games.

The Tesla car application on my phone sent an alarm notification: [Abnormal vibrations detected in the car. Please check.]

Following the location sent, I arrived at the parking lot below my wife's company. I saw her sweating profusely in the car with her fitness instructor.

My mind went blank. Suddenly, a mechanical voice rang out in my mind: [Congratulations! You have been linked to the Cuckold King system. Complete the task, and you will receive $100 million as a reward!]

The mechanical voice finished speaking. My hand froze, gripping my phone.

The system's voice was indifferent and emotionless.

[New Noob-level Mission: Resist the temptation to expose them. Stay outside the car, don't disturb them, and take a photo of the two.]

[Mission Reward: $1 million in cash. Revenge main quest unlocked.]

[Failure Penalty: Elimination of the host.]

I stared at the familiar Tesla Model 3. It was the new car I had just purchased last month for my wife, Joanna Laker, to drive around.

The car body was shaking rhythmically and violently. I could vaguely hear the nauseating sounds coming from inside.

My nails dug into the car paint.

I wanted to smash the car window and drag the adulterous couple out to kill them, but the system's red warning light was flashing wildly.

I took a deep breath, forcibly suppressing the surging anger in my chest. Trembling, I raised my phone. With the help of the dim street lights, I aimed my camera at the car window.

Click! I took three photos in succession.

[Task completed. $1 million has been credited.]

My phone vibrated. A text message from my bank followed immediately.

Looking at the extra string of zeros in my balance, the corner of my eye twitched.

A few minutes later, the shaking of the car stopped.

The door opened. A disheveled Joanna stepped out and adjusted her skirt.

A shirtless Greg Adams followed behind with a smug look, giving Joanna a hard squeeze on the waist. "Joanna, you have a very strong core."

Joanna playfully punched him. "Hey, what if someone sees us?"

Greg scoffed. "So what if they see us? What can your useless husband do to me?"

I hid in the shadows behind a stone pillar, clenching my teeth until I tasted the metallic taste of blood.

I composed myself, pretending to have just arrived, and stepped out of the shadows.

My footsteps startled them.

Joanna screamed in fright, her face instantly turning deathly pale.

Greg reacted quickly, shielding Joanna behind him and looking at me defiantly. "Oh, isn't this Mr. Noah Hughes? What are you doing here?"

When Joanna saw it was me, the panic in her eyes instantly turned to disgust. She struck first. "Noah! Were you following me?"

I looked at the still-visible red mark on her neck. Forcing back the nausea in my stomach, I forced a smile that looked more like a grimace. "The app alerted me that the car was vibrating abnormally. I was worried something might've happened to you, so I came to check and pick you up from work."

Joanna paused for a moment before resuming her haughty demeanor. "The car just broke down! Mr. Adams happened to be passing by and fixed it for me. What kind of dirty thoughts are you projecting onto me?"

Greg crossed his arms, looking at me contemptuously. "Yeah, Noah. Why are you so suspicious? No wonder Joanna said she felt suffocated with you. Men should be more magnanimous."

As he spoke, he straightened Joanna's disheveled collar right in front of me, unabashed at acting so intimately with her.

I clenched and unclenched my fist.

Just then, the system issued another task.

[Mission #2: Invite the other man to have supper and offer to pay.]

[Mission Reward: $500,000 in cash, patience level +10.]

Looking at their repulsive faces, I smiled and extended the invitation. "Since Mr. Adams has been so helpful, how about we have supper together to show him our gratitude?"

Greg unceremoniously ordered enough oysters and clams to cover the whole table.

"Noah, eat more of these oysters. They are good for you." Greg glanced meaningfully at Joanna. "Joanna often complains to me that you're lacking in a certain area."

Then he picked up a bunch of clams and bit into them, coating his mouth with the sauce.

Joanna sat next to Greg and across from me at the table. She did not refute him. Instead, she covered her mouth and chuckled. "Greg, don't speak nonsense. Leave him with some dignity."

Under the table, I could clearly see Greg rubbing Joanna's calf with his foot. Joanna did not dodge. Instead, she lifted her foot and hooked it around his.

[Patience level is rising... Current progress: 10%.]

The system's notification echoed in my mind.

Greg opened a bottle of beer and pushed it right in front of me. "Come on, drink! Don't act like a girl. I heard your monthly salary is only $8,000? Joanna must've suffered being with you."

Joanna sighed and looked at me bitterly. "Yeah. I wanted to buy that new bag, but he kept dragging his feet. Greg is better. That necklace he gave me back then was worth over $10,000, and he gave it to me without even blinking."

I picked up the wine glass and politely filled Greg's glass instead of getting angry. "You're right. I'm indeed incapable. I'll need your help with Joanna's fitness routine from now on."

Greg laughed and reached out to hold Joanna's shoulder. "Don't worry. I'll train her well."

Joanna blushed and shyly pushed him away, but her efforts failed.

When it was time to pay, the waiter brought the bill over. "Sir, that'll be $860."

I took out the card my salary was paid to and deliberately made the swipe fail. "Sorry, insufficient balance."

I awkwardly scratched my head and used a credit card.

Greg scoffed and spat on the ground. "What a nuisance, having to use a credit card for a meal. Joanna, what do you see in a man like this?"

Joanna rolled her eyes and took Greg's arm. "I see him as honest and easy to control."

On the way home, Joanna sat in the passenger seat and covered her nose. "Noah, what's that smell in the car? It smells fishy. Get the car washed tomorrow. Give it a thorough cleaning inside and out. Also, Greg said he's a little short on cash lately. Don't you have $50,000 left on your credit card limit? Cash it out and lend it to him."

The veins on the back of my hand gripping the steering wheel bulged as I nodded in agreement. "Okay."

[Mission completed! Reward: Panoramic listening device.]

Back at home, I slipped the miniature listening device into the fold of her phone case while Joanna was taking a shower.

I put on my earphones and immediately heard the sound of water from the bathroom and Joanna's voice as she sent a voice message, "Darling, that idiot agreed. Tomorrow, I'll make him cash it out. Also, we need to hurry up with that thing we discussed. I'll transfer his premarital assets and then dump him."

Greg's voice came through. "Hehe, you're smart. Did I hurt you tonight?"

"Hehe, shut up! You're so annoying..." I took off my headphones and threw them on the table. My stomach churned.

The bathroom door opened. Joanna came out wrapped in a towel, her hair still wet. She walked up to me and looked condescendingly at me. "Noah, I think we should have a child."

She touched her belly, her face serious. "I've thought about it. I'm not getting any younger. Go to the hospital for a full checkup tomorrow, especially for your sperm motility. Also, for the sake of raising our child, you'll have to give me your bank card from now on. Men shouldn't have money. Money corrupts you."

The next morning, I pretended to go to the hospital for a checkup, but I actually went to the bank and the Ministry of Housing.

The results chilled me to the core.

The card in my name, with $500,000 in savings, had been emptied by Joanna in batches. The remarks were all 'loans' or 'shopping'. The recipients were all Greg.

This half a million dollars was the inheritance left to me by my parents, and it was also the down payment I was planning to use to buy a bigger house. Now, it was all gone.

Greg's social media feed just updated with a photo of him collecting a car. It was a brand new BMW 5 Series.

The caption wrote: [Hard work pays off. Here's a big toy I'm rewarding myself with!]

His 'toy' was bought with my hard-earned money.

When I got home, Joanna was sitting on the couch applying a face mask. Seeing me back, she handed me a health examination report. "Noah, take a look for yourself."

I picked it up and looked at it. The report was fake. It said I had severe asthenospermia, and my chances of conceiving naturally were extremely low.

"The doctor said you'll basically never become a father."

Joanna looked disdainful, with deep contempt in her eyes. "No wonder we haven't had any luck in conceiving during our three-year marriage. Noah, are you even a man?"

I had just opened my mouth when my phone vibrated.

Greg had sent a message. I clicked on it to open a video. The background was the gym's locker room.

In the video, Joanna was kneeling on the ground, looking up. The scene was unbearable to look at.

Then, there was a text message.

Greg: [Your wife feels so nice, but you can't make her happy. I'll make the baby for you.]

Smash! I smashed the glass cup in my hand hard on the ground, and fragments flew everywhere.

[Warning! Warning! Impulsiveness during the mission will result in the system being unlinked and the host being eliminated!]

The system's red light blared again.

I gasped for breath, my chest heaving.

Joanna was startled, screaming, "Noah, what's wrong with you? You can't perform, yet you have the nerve to throw a tantrum? Clean up the floor! If you cut my foot, I won't spare you!"

I crouched down, picking up the glass shards one by one. The sharp edges cut my fingers, and blood dripped onto the floor. The pain brought me back to my senses.

That evening, Joanna brought Greg home. She called it her personal trainer's at-home fertility yoga sessions.

"Since you can't perform, I'll have to get my body in shape. Even if we do IVF, we need a good foundation," Joanna said matter-of-factly.

Yoga mats were laid out in the living room. The two of them did partner yoga in front of me, and their movements were extremely suggestive.

Joanna let out soft moans, completely ignoring me.

I was sitting on the couch next to them, watching this scene unfold.

[New Extreme-Level Mission: Hand them water, wipe their sweat, and compliment Greg's physique.]

[Mission Reward: $5 million in cash, Patience level +20.]

I stood up, poured two glasses of cold water, grabbed a towel, and walked over to them.

Greg was on top of Joanna. Seeing me approach, he whistled provocatively. "Oh, Hughes, you're so thoughtful."

I handed him the water and picked up a towel.

Greg deliberately brought his sweaty face closer. "Here, wipe me down."

I took the towel and gently wiped his face like a servant attending to his master.

"Mr. Adams, you have a great physique. I could never build muscles like that in my entire life," I said with a smile.

Greg patted his chest muscles proudly. "Of course. A man has to be tough, unlike a spineless wimp like you."

Joanna lay on the mat, her eyes alluring. "All right, ignore that loser. Greg, let's continue."

It was late, yet Greg showed no sign of leaving.

"Oh, it's too late. I'm too lazy to go back." He stretched and looked at Joanna.

Joanna immediately chimed in, "Then stay for the night. The guest room is empty, anyway."

She turned to me and ordered, "Noah, go make Greg's bed. Get that new silk comforter. Don't use your old one. It's dirty."

I turned around to enter the guest room and take out a new quilt from the cupboard.

As I made the bed, my hand reached under the pillow, where a pair of scissors lay.

I gripped the handle. The icy touch sent a chill through my body. Just one stab. Just one stab into that monster's neck…

[Patience level 99%... Almost full.]

[Please endure the final mission.]
