What Are The Best Arcs In 'I Can Copy And Evolve Talents'?

My best friend, Clara Wilder, has baked an apple pie for me. But I don't hesitate to give it to my pregnant dog. That's because I've gotten reborn. In my previous lifetime, Clara had bound the Fertility Transfer System to me. If I were to eat the food she made, the baby I was pregnant with would be transferred into her womb, and she would be the one giving birth to them. Clara had married into the wealthy Gray family. For three generations, the Grays were only able to produce one heir each. That was why her in-laws desperately needed her to bear them grandchildren. Since Clara couldn't get pregnant at all, she decided to target me, her newly-wedded best friend. I went to great lengths just to get pregnant every time, but right after I ate the food Clara made, I'd go through a miscarriage by accident. Just like that, Clara was able to give birth to four sons in a row. She became the apple of her in-laws and her husband, Colton Gray's eye, which made her ego swell like mad. In the end, Clara and Colton hatched a plot where they accused me of cheating on my own husband. With my reputation flushed down the drain, I got kicked out by my in-laws. In the end, I starved to death on the streets without a penny under my name. At the end of the day, Clara wants children very badly, doesn't she? After I get reborn, I decide to give her some special "babies".

Mom and Dad aren't bothered at all when I completely start slacking off. Kennedy Quinlan, my girlfriend's brother, who has established a reputation as a genius inventor, completely breaks down, while I slack off instead of conducting research in the lab. In my past life, Kennedy files an identical patent application just one day before I do, causing everyone to brand me as a fraud and accuse me of blatant plagiarism. I try to explain myself, but no one believes me. Kennedy eventually launches a live stream to blast me online, accusing me of trying to scam my way into their family's fortune. They run a massive cyberbullying campaign against my whole family. Mom and Dad only want to clear things up, but Kennedy's crazed fans push them off a high-rise building, leaving them to die in unresolved grief. Unable to handle the blow, I fall into a severe depression and end up slitting my wrists. I still can't wrap my head around the whole situation, even in my final moments. It is obviously the fruit of my own painstaking research, so why does someone else get to file the patent first? I suddenly open my eyes and find myself back on the day before my invention is stolen.

The first thing I do after being reborn is secretly keeping six stunning male models behind my wealthy husband’s back. I seduce them and sleep with them for 999 days to get myself pregnant. I do all this because in my past life, my husband found out that he had asthenozoospermia and married me because I am known for being fertile. He wants to carry on the family line so that he will have a successor to inherit the family fortune. I try everything I can to get pregnant, but nothing works. Conversely, my infertile best friend gives birth to twins and triplets within two years after marrying a 70-year-old man. When my wealthy husband hears that my best friend is blessed with children, he is immediately captivated. They get together behind my back and even arrange for someone to run me over with a car when I find out the truth. After my death, I discover that my best friend has bound herself to the child switch system. Any child I am impregnated with is transferred into her womb. My best friend's infertility is transferred to me in return. When I open my eyes again, I find myself back on the day when my husband married me and brought me home. I smile happily when I think about all the things that took place in my past life. My best friend wants lots of children, doesn't she? If so, I will make her experience the joy of having 18 babies in one pregnancy!

A week before the college entrance exam, my twin brother, Tristan Doyle, runs away with a delinquent. Our parents abandon their massive corporate empire and set out to search for him. I intend to join the search, but a comment abruptly flashes across my vision. "Don't go, Ryan! If you skip the exam too, your family is doomed!" With no other choice, I shoulder the pressure and walk into the exam hall alone. Yet the moment the exams end, my parents return and lock me in the basement. Ten years later, I finally escape, only to discover that Tristan has stolen my identity. He's celebrated as that year's top scorer, gets a degree from a prestigious university, and is even married to my former high-achieving girlfriend, Alisha Hudson. They share a perfect life with two children. Furious, I attempt to confront them, but they bind me and throw me back into the basement. As I howl in rage, my parents reprimand me, "Tristan was never as smart as you, and that delinquent tricked him into running away. There was no way he could've gotten into college on his own." "You're his older brother. What's wrong with letting him have one thing? Stop being so selfish." I break down completely and die in despair. Only after my death do I learn that Tristan was the one who sent that comment. When I open my eyes again, I'm back on the day Tristan elopes with the delinquent. The comment appears once more. As I stand there frozen, Alisha gently nudges me with a smile. "Go study! Your whole family's counting on you."

My younger sister, Chloe, and I were transmigrated together into a beastworld continent. Beastmen are classified into four distinct ranks: S, A, B, and C. The tribe chieftain, Gideon, gathered all the single beastmen in the tribe for us to choose from. Chloe chose Garrett, the only A-rank werewolf in the entire tribe. She gave birth to five consecutive litters, yet all her children turned out to be mere B-rank beastmen. Furious, Garrett dissolved their mating bond. The other males refused to take her in either, entirely because the offspring she produced were of a mediocre grade. Meanwhile, I chose a B-rank snake shifter and gave birth to ten children in a single litter—all of whom were A-rank. The entire tribe revered me as a divine lady, and the snake shifter successfully inherited Gideon's position. Consumed by sheer jealousy, Chloe poisoned my ten children to death and pushed me off a cliff, leaving me to plunge to my death. Yet, when I opened my eyes again, we had returned to the exact day of selecting our mates. Without a single moment of hesitation, Chloe chose the snake shifter. I knew right then that she had been reincarnated too. But this time, the children she gave birth to would not even qualify as C-rank.

My best friend has always been stingy to the bone, so the moment she volunteers to buy a bottle of water for the heir to Bellaris' most powerful family, who collapsed from heatstroke, I know she has been reborn, too. In my previous life, she and I sat for the college entrance exam together, and when the results were announced, we both got the same high score. Both of us had our eyes on Kingsley University, yet the admissions quota was limited, and neither of us wanted to jeopardize our friendship, so we kept delaying our application. In the blink of an eye, it was the last day to file our applications, and as I was about to start on mine, I stumbled upon the heir to Bellaris' most powerful family, who happened to be suffering from heatstroke. I not only bought him a bottle of water, but I also held an umbrella over him until he came to. By the time he regained consciousness, I had already missed the submission deadline. My best friend submitted hers just in time and got accepted into Kingsley University. Because I never submitted mine, the opportunity to attend university slipped past me. However, the heir apparent was touched by my act of kindness, and he asked for my hand in marriage. In the end, I married him and became a socialite, whereas my best friend, despite getting into Kingsley University, was overwhelmed by the demanding curriculum. Watching me live with more money than I could spend, she was fueled with jealousy until one day, she snapped and stabbed me. The moment I open my eyes again, my best friend and I are back on the day the heir to Bellaris' most powerful family passes out from the heat.
