MTL - Tempered Immortal - v5 Chapter 4155 True magic broken knife

Nie AnAn woke up one day and realized that she had transmigrated as the villain’s adoptive sister.

In the novel, the villain conquered left and right, and his always woe-is-me younger sister was always cleaning up after him. The two of them were rightfully the grim reapers in the book.

The very next day after her transmigration, the soft and delicious Nie AnAn passed out from seeing blood.

And so —

The shivering competitors noticed that their nemesis’s sister had turned to a delicious treat — and wanted to protect her;

The original male lead noticed that young Miss Nie, who had been chasing after him this entire time, wouldn’t even give him the time of day anymore — and felt unbalanced;

Young Master Nie was very happy that his parents had two kids back then– she was so GD cute;

A certain cold blooded and violent villain had been going home earlier and earlier, and the way he talked was becoming gentler and gentler.

Villain Brother: AnAn, come over. Let me try some of it.
Nie AnAn: Hold on, gege. It’s not ready yet.

Two years ago, Nina married a man she had never met. She didn’t know his name or his age; she knew nothing about this person she was married to. Their marriage was nothing more than a contract with conditions, and one of the clauses was that she should not sleep with another man.

Yet, Nina lost her virginity to a stranger when she knocked at the wrong door one night.

With the compensation she had to pay weighing her down, she decided to draw up a divorce agreement on her own.

When she finally met her husband to hand over the papers, she was shocked to find that her husband was none other than the man she had “cheated” on him with!
