In fact, Ling Yun was the son of a wealthy businessman. But one day, his mother finds out that her husband is having an affair with his secretary. And after that she decided to divorce her husband, but at that time she did not realize that she was pregnant with Ling Yun.

After learning about her pregnancy, she decided to move to another city. And since then, their lives have been up and down. Because of the economic crush, and also his mother's health was getting worse.

He decided to take the 'Dark' path, which led him to near death. But just as Ling Yun was nearing his end, he heard a little girl's voice asking him.

“Do you want to live?”

When Qin Yan was five years old, she left the capital with her mother and went to the Pingxi Army under the command of her grandfather, Duke of Zhenguo, in the Northwest. When she returned twelve years later, things were different.

After the mother was attacked and disappeared, everyone in the Prime Minister Mansion only knew of Concubine Song, but not her mother, the honorable mistress. They only knew that there was only one Miss Nian in the mansion, and they did not know that there was also her, the only eldest young lady of the first wife.

The concubine took over her mother’s dowry and pretended to be rich and generous to win people’s hearts. The concubine-born younger sister, with the identity that belongs to Qin Yan, was mixed up like a fish in water in the circle of noble daughters in the capital, and she also intended to get involved with Qin Yan’s fiancé.

The people in Prime Minister Mansion thought that Qin Yan could only be at their mercy when she returned to the capital alone. However, they never thought that within a few days of returning to the capital, Qin Yan was granted the title of Princess of Zhaoren by the emperor and given a palace as the Princess Mansion.

When Qin Yan took back the dowry that belonged to her mother, only then did her father Prime Minister Qin and Concubine Song knew that Qin Yan was the owner of Yu Qingfeng, the first bank in Great Xia.

The City Master of Gu City, an important town outside the Northwest Pass, was known as the owner of Yu Qingfeng, the first bank in Great Xia which claimed to be able to reach half the national treasury.

It was only after Su Yayan's death that she realized that she was a malicious cannon fodder female character who became a scapegoat in a Mary Sue story.

“This guy, how heavy is his taste, he’s still able to eat?” Waking up, she looked at her reflection in the mirror, explosive hair, tattoos, and a demon-like face. Look at her for more than a second and you’ll have spicy eyes (your eyes will bleed-aka she looks really ugly).
