MTL - The Life of a Villain Starting From Naruto - Chapter 124 so the answer is

Liu Sanniang was reborn. When she remembered her lonely end, she decided to get married in this life no matter what.

She only wanted to marry an average scholar, but who knew that the tall and striking future general, Chu Yan, took an interest in her.

The first time they met, she was too shy to look up at him.

The second time they met, he sandwiched her against the wall and said, “Are you afraid of me?”

The third time they met, he squatted down and said, “Come on, I’ll carry you.”

***

After meeting a few more times, he came to ask for her hand.

However, he was at least two meters tall and muscular. She feared that he might squash her to death!

Once they got married, Chu Yan strode over to her and ‘forcefully’ grabbed her hand, ready to pass his life savings to her. Yet, his delicate and beautiful bride fainted out of shock…

Liu Sanniang then realized that being with her ‘scary’ husband meant living peaceful and leisurely days, so her eyes narrowed as she grinned.

“Live the life you want this time.”

A peerless assassin, codename: Hua, has already started her career ever since she was a child. Her mission’s record was perfect and whoever deemed to be her enemies would end up dead without knowing why.

When war ended, she was sent to an institution where she was watched heavily. The doctor in charge gave her an ordinary wuxia novel to read.

An avalanche struck after she had finished reading.

When she woke up, she had turned into Nan Hua, the young miss

Beings that create and control monsters and demons, beings that build and reign over malicious labyrinths, the chosen individuals to possess an overwhelming Unique Skill… They are the Demon Lords.

Liang Yi transmigrated into the book, and became the vicious widow in the farming novel, the kind of 18th-line cannon fodder.

The original owner was good-looking, but vulgar and pungent. He bullied his younger uncle and beat and scolded his two stepson all day long.

What’s worse is that her brother-in-law is Zhou Zhongming, the hero of this book, and he is also a ruthless character who holds vengeance.

Bear the humiliation now, wait for him to come to be an extremely human minister, remember how this sister-in-law abused him and his nephew

——Liang Yi felt chilly on her neck.

No sooner had the male protagonist returned home, his eyes turned red: You wicked woman, I will definitely divorce you for my brother!

But what’s even more tragic is that just as she was about to play the tender route to gain the male lead’s favor, she was reminded by the angina pectoris

——For the sake of her life, she can’t even destroy the human design!

Liang Yi had no choice but to follow the plot, playing the role of the vicious stepmother and the mean and vulgar widow.

By the way, she also made preparations to get off the assembly line on time, and quietly revitalized her vest.

But who knew, the letter of divorce did not arrive for a long time, and the hero became a general but gave her a dowry.

Liang Yi: The male protagonist, please show some respect, I am a vicious female supporting role!

Zhou Zhongming: I know you are a goblin, marrying you is the only way to eliminate harm for the people!
