Many islands dotted the vast oceans of this world. However, some of the islands were a lot more sinister than the rest. Those islands, known as Nightmare Islands, were true nightmares to all but the strongest and most fortunate. Children were kidnapped and thrown on these isolated islands by the Nightmare Palace, forced to sign soul pacts with evil soul pets: Nightmares. These devils slowly devoured the souls of their trainers to grow stronger. If the children did not cultivate fast enough, their souls will be devoured whole, leaving only an empty husk behind.

Chu Mu, the protagonist, was an heir to the Chu Clan, but due to a plotted murder, he was thrown on the island, sentencing him to almost certain death. Dancing on the edge of life and death, he struggled to survive with a small Moonlight Fox he captured. When he finally escaped the devilish foremen on his island, he couldn’t help but let a breath out. But little does he know, the experience was only a beginning to a fated journey with his little Moonlight Fox…

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.
