MTL - Positive Energy System - Chapter 13 Doom of the Liar

Arnold never thought his gaming skills would land him in a romance novel—as a doomed side character, no less. To survive, he hijacks the heroine's “system,” bending the story to his will. But when he dodges a deadly duel, he catches the eye of the heroine, Lara, his own step sister—and her love is a dangerous game. Arnold must outwit the plot and his step sister who's not afraid to kill for love. In this LitRPG romance gone wrong, survival isn't just about beating the system—it's about escaping the heart of a yandere.

Qiao Mei transmigrated into a novel as a supporting character with the same name as her who lacked presence. This supporting character was a country bumpkin who couldn’t get married due to her obesity. According to the original script, this country girl Qiao Mei was a fatty spoiled by her grandfather. However, their relatives were all vicious and cruel people. Her grandfather had poor health, so once he died, the relatives would divide and swallow up his assets. Hence, her grandfather’s greatest wish was to marry Qiao Mei off. For this, even sacrificed and betrayed his good friend’s grandson, Xia Zhe. Grandpa got Xia Zhe drunk and had Qiao Mei forcibly take the strong and handsome Xia Zhe with her body which weighed more than two hundred pounds. Then, grandpa would catch them the next day and force Xia Zhe to marry Qiao Mei. However, that eventually caused the start of Qiao Mei’s unfortunate life.

From the age of 7, Qiao Qiao realised that her family wasn’t quite the same as her friends’ families.

Her father, dressed in all white, said, “Our girl should learn to cultivate immortality with me!”

Her mother, dressed in battle armor, said, “Our girl should train her body to protect herself!”

When discussing it, they decided to solve it with a duel outside.

Her brother secretly asked, “Qiao Qiao, do you want to be in the entertainment industry with me?”

Then, her brother was kicked out of the house by her parents. She prayed that he was okay out there. 

Qiao Qiao sighed. She was really worried about this family.

She silently collected mech building materials. There was no other way, if she learned how to use mechs, she would be able to get a good job. Unfortunately, her unreliable parents didn’t understand.

It seems like the burden of supporting this family was handed over to her.
