Temporal Pearls - Chapter 5: Weapon Arena!

The story begins similarlly—a mid-level corporate worker dies and awakens in another world as a 19-year-old—but from there, Eren follows a very different path.Erik, a mid-level office worker, had a simple dream:“Graduate college.Get a job.Screw MILFs.”But reality wasn't so kind to him. Due to his hastiness, he forgot to check the company's background and accidentally enlisted himself into a black company—a corporate hellhole that literally made employees work to death.Such was the fate of our protagonist, Erik.Exhausted after working nonstop 12-hour shifts for seven days straight, he lost his grip on reality and met a meaningless death, collapsing onto his desk in an office nobody would mourn.Yet, reality wasn't entirely cruel either.He suddenly transmigrated into the body of an 18-year-old—young, energetic, muscular, and brimming with vitality. And best of all?He woke up sleeping right next to someone!“What? I'm transmigrated sleeping right next to my step-aunt?!”Even crazier: in this new world, beauty standards were completely reversed. Here, the pinnacle of femininity was a skinny figure with small boobs and an even smaller ass, and women who didn’t fit that mold—busty, curvy MILFs—were mostly ignored, discarded, and lonely.“How crazy is that?” Eren voiced, grinning from ear to ear.But all of that was about to change, since he was here now. He'd make all MILFs his—starting with his deliciously thick, step-aunt.

When Su Yaya awakened, she found herself in a novel world as the CEO’s Substitute Wife–-a mere cannon fodder. Knowing that divorce and a tragic ending was awaiting her once her look-alike, the President’s first love returns, Su Yaya only trusted one thing: Money.

She curried favor with her husband each day, saved up resources, and served him as a faithful wife. It was better to leave a good impression on him before separation so she could avoid her death flags.

The overbearing President was very satisfied with her and personally gave her his platinum card: “Take it and buy anything you’d like!” Su Yaya happily accepted. Of course she would take advantage of his pampering before the female protagonist appears!

As the CEO unexpectedly falls deeper despite this transactional relationship, he never imagined that his wife would one day disappear from his side.

Chu Mu Yun relied on his story of 《Demon Realm》 to become a one-hit wonder in JJWXC, but the him who had written seven mental cases to abuse seven mental cases to death would never have expected that he himself would transmigrate into this shitty novel!
What the hell is this system on the bracelet?
And what the hell is this either propose to seven men, or suffer the taste of a tragic death experience under the hands of these seven people?
I just wanted to write a novel to satisfy my bad interests, who would actually want to get tangled up with a bunch of mad dog sad*st crazies?
