Original name: Prince Charming's Next Door, finished. One day, she slept with him accidentally. Two month later, she found herself pregnant, so they got married with baby. “Mr. Gu, I like the dishes of this restaurant.” Then the chef of that restaurant was hired as theirs. “Mr. Gu, I like the bags of that brand.” Then the designer of that brand was employed exclusively for her. She thought of herself as a stranger to him after marriage as she had always been, but in fact he doted on her totally beyond her imagination. He would satisfy all her demands, except letting her find a job. She kind of got anxiously bored at home, so she sneaked out to find herself a job. However, whichever company she was hired by would go bankrupt somehow or other. Finally, she got to know it had been always him who had done mischief surreptitiously. She went to question him angrily, but he gave her a job with a smirky smile. The next day when she went to take the office with delight, she found her employee ID card on the desk said ‘Name: Qin Zhi’ai, Position: Wife of Gu Yusheng’.

# HUSBAND-CHASING Si Mi had been foolish in her past life. She aborted the child she had with her husband just so she could return to her first boyfriend, Fu Xing. Yet, Fu Xing had no intention of reconciling with her, and even ridiculed her for flattering herself. With that, Si Mi felt that she had been abandoned by the world. She wandered the streets dejectedly and was killed by a car that malfunctioned. As her soul floated in midair, she saw her stepsister secretly meeting up with the driver who killed her to give him a large sum of hush money. She even saw her stepmother, who had always doted on her, say, “That girl finally died. At least my efforts weren’t wasted in spoiling her to the point of being brainless and arrogant! My dear daughter, you can finally relax and be with Fu Xing now.” Finally, Si Mi saw her ex-husband attending her funeral, and then took revenge for her death. Her supposedly disfigured husband even removed his mask for the first time before her portrait. The man’s flawless appearance seemed to be a gift from the gods. Every inch of him was meticulously perfect, and he wasn’t as hideous as the rumors painted him to be. Then, Si Mi lost all senses. When she opened her eyes, she found herself lying on a bed naked while a man rammed into her from above. It was her husband, Fu Zhen! She had just attended her own funeral moments ago as a wandering soul, so why was she in Fu Zhen’s bed now and making love to him? It seems that Si Mi was reborn back to the time when she had just married her husband. During this time, she had yet to abort Fu Zhen’s child, and hadn’t yet fallen into her stepmother and stepsister’s scheme! What perplexed Si Mi even more was that she now possessed the power of telekinesis after being reborn. Splendid! She swore not to be toyed with anymore in this life. She would also take revenge! More importantly… she had to compensate Fu Zhen for what she owed him. She would give her best to this man who once loved her deeply.

The live show, Survive in Wilderness was a hit. There were thousands of participants in the game show. They would all start by parachuting from a plane and land randomly in a primary forest. The participants would have to rely only on a backpack, a water bottle, and a dagger to survive. Yu Beier was only eight years old when he joined the game show so that he could buy the cure for his ill mother with the prize money. He was the youngest to have ever participated, and he had accidentally woken up a wilderness survival system. [Ding! You have received the Wilderness Survival 101 Pack!] [Ding! You have received Max-leveled Hunting Skill!] [Ding! You have received Max-leveled Building Skill!] [Ding! You have received Max-leveled Swing Skill!] … When the show started, the viewers were utterly shocked. From climbing the tallest mountain to crossing the ocean, conquering the forest and swamp, and managing an island, there was nothing that Yu Beier could not do. “Dude! That eight-year-old boy is living a much more interesting life than us!” “Yu Beier is the apex among men!” "Whenever I see his stream, it feels like I've just lived an extra life!"
