Global Reincarnation: Only I Know the Plot - Chapter 971:

Among the demons, the supreme ones are called “Great Saints.”

Xueyue's life was filled with nothing but unfortunate events. Her mother died giving birth to her, her father abandoned her for another family, her stepsister stole her beloved, and she was framed for a murder she didn't commit.
Sentenced to death by beating, Xueyue thought her horrible life would finally end.

In the era of universal mechas, people can go to the endless abyss, collect materials, strengthen and forge their own mechas, and master the power of destroying the world.

Jiang Chen traveled through time and awakened his talent [Immortal Unarmed]. Once the mecha is broken, he can permanently absorb its power and receive multiple bonuses.

…

At the bottom of the abyss, when the Old Demon God finally broke the Titan mecha with great effort, a hand stretched out from the fragments and held down its head.

“Congratulations, you have unlocked my limiter.”

- Description from novelbuddy

Despite having found Mingxi, the Zhao family continued to favor the fake daughter, saying that Mingxi was not as kind nor as graceful as Zhao Yuan.

Mingxi didn’t mind. She continued to work hard to please her family although they would always say that she was trying to rob their attention away from Zhao Yuan.

Until she died because of a terminal illness.

It was then that she realized that Zhao Yuan was the actual lady blessed by luck while she was merely this novel’s evil supporting character with a tragic ending.

Zhao Mingxi who was given a second chance at life was bitterly disappointed. She no longer cared about her family. Screw her family and her fiancé. She immediately packed her bags and left home, off to complete the task given by the system named ‘Becoming Friends With Fashionable and Valuable Characters’.

After she left, the house suddenly became cold and quiet.

By right they should feel at ease, but–

Her parents, her indifferent elder brother, her brash younger brother, Chen Liyao who was used to her pursuits were all successively feeling… unused to it?
