In the MCU/Marvel with the Omnitrix/Ultimatrix - Chapter 1: Are you fucking kidding me?!

A Di [legitimate-born] daughter of a noble house turns into an abandoned daughter. No father to dote on her, no mother to love her, no problem. She uses one silver needle to save a dying man. What’s so unusual about a medical injection? She roams all over the world with a scalpel in her hand. Cutting throats, cutting open abdomens, cutting open skulls to mend bones. With amazing medical skills and ethics, she gathers a flock of officials, obtains the will of heavens, gains public favor, and receives Taizi’s [Crown Prince] doting. In the midst of a powerful momentum, her cheap father comes to reunite. She coldly refuses to go home or acknowledge ancestors.

The Revered Master, Yu Yan, known as the number one in the cultivation world, waited for sixteen thousand years, and finally took in a disciple. He taught her carefully, and took care of her diligently. He watched her as she slowly grew stronger as she comprehended the laws, and just as she was about to soar into prominence… she died!

Five years ago, Gu Qiqi’s best friend’s boyfriend cheated on her. She helped arrest someone, but she caught her fiancé. When she left, she was dragged into the room by a mysterious person…

Five years later, Gu Qiqi married Yan Haocheng, who had some problems in city A, with twins whose father was unknown. Everyone felt that Gu Qiqi must have married Yan Haocheng by virtue of his “special ability”.

But she didn’t know that it was Yan Haocheng who didn’t want to marry her. She was afraid that he would die alone, so she gave up and married.

Other people’s impression of Yan Haocheng is: cold, scary, and without desires.

Gu Qiqi’s impression of Yan Haocheng is: shameless, shameless, humanoid teddy.

Others rely on beauty to attract men, but Gu Qiqi only needs to wink at the child to turn her man into a puppy.
