Marvel: Rise of the Ultimate AI - Chapter 183: Ultron, the Little Brother

Growing up in poverty, Sunny never expected anything good from life. However, even he did not anticipate being chosen by the Nightmare Spell and becoming one of the Awakened - an elite group of people gifted with supernatural powers. Transported into a ruined magical world, he found himself facing against terrible monsters - and other Awakened - in a deadly battle of survival.
What's worse, the divine power he received happened to possess a small, but potentially fatal side effect...

After choking to death on a watermelon, Rong Jiahui thought that she would enter the netherworld and be reincarnated.

But when she opened her eyes, she discovered, to her very horror, that she had returned twelve years into the past…

Looking at the beautiful and awkward “little brother” that would be conferred the title of Marshal in the future for outstanding military service, she almost let out a snort of laughter.

She firmly decided to hug the thigh of this little brother, and climb to the top of her life!

The plan was beautiful, but it had just one problem.

Why had this little brother… suddenly turned into…

A little sister…

Zhuang Xian was abducted when she was three years old and lived in an orphanage until she was sixteen when the Zhuang family adopted her. From then on, she jumped from being an orphan with nothing to a little princess. But she wasn’t satisfied. She wanted to find her birth parents and get their love, but she didn’t expect to instead find a family of jackals and snakes. They took advantage of her trust to annex her adoptive parents’ company and forced them to their deaths.

Her three brothers fled abroad, while Zhuang Xian was beaten and scolded by everyone. Locked in a warehouse, she was forced to endure torture for the whole month with a clear mind thanks to drugs. In the end, she died miserably due to her fiance and her sister’s plotting against her. That cheating scumbag and prostitute! Zhuang Xian swore before her death that if there was a next life, she would be willing to do anything for the Zhuang family, and she wouldn’t let these people deceive her like this again! She would make sure that those who treated her well would have a good life! Zhuang Xian didn’t get the next life, but she did return to the first three years of her adoption. For three years, she stayed under the radar and created multiple identities for herself.

When three years were up, she returned to the Zhuang family and beat up those scumbags, while her three brothers doted on her as though she was a treasure! Outsiders say that the Zhuang family’s adopted daughter didn’t learn well when she was younger, that she was completely illiterate, and that she was stubborn. The reason she was rejected by her previous adoptive family was that she was prone to stealing.

However… She was the Chess Saint, the Gold Medalist Designer, and also the world’s best doctor! All of them were her! There was also the crazy slave-like man who loved to spoil her and loved to show off his wife, “Zhuang Xian is beautiful, right? She’s my wife!”

Witnessing her boyfriend cheating on her with her bestie, Shiyao was so angry that she went to a pub for fun and met a man, who was really a piece of work. After a crazy night she fled away, but was embarrassed to know that the man she slept with was her boss You Ze.
Jesus, give her a break!
