The youngest, silly fourteenth son of the Yan Emperor had reached the age where he should be given a separated territory now. He rejected the wealthy land, neighbouring the capital city, and instead chose the wildest land in the western region— Liangcheng. Everyone shook their heads and sighed. A fool is indeed a fool. If you go to Liangcheng, you will be killed by barbarians in less than three to five years.

One year later, the watermelon presented to the Emperor as the tribute from Liangcheng in the west was sweet and crispy. There was no one in the palace who did not love it.

Two years later, Liangcheng presented corn as a tribute to the Emperor. The yield was high, and the taste was good. No one in the country could resist liking it.

Three years later, Liangcheng defeated the barbarians and presented their prisoners in front of the imperial court. The people of Yan were excited and their morale was greatly boosted.

Four years later… Everyone said that the fourteenth prince Mingyu was a fool, while the little fatty Yu, who transmigrated with the golden finger, chuckled. Let’s see how you guys look at this fool build his own territory, then.

Chu Mu Yun relied on his story of 《Demon Realm》 to become a one-hit wonder in JJWXC, but the him who had written seven mental cases to abuse seven mental cases to death would never have expected that he himself would transmigrate into this shitty novel!
What the hell is this system on the bracelet?
And what the hell is this either propose to seven men, or suffer the taste of a tragic death experience under the hands of these seven people?
I just wanted to write a novel to satisfy my bad interests, who would actually want to get tangled up with a bunch of mad dog sad*st crazies?

Yu Youyao had a nightmare. In her dream, she was married to the Marquis’ son, Song Mingzhao, and had become a mere medicine-human for her third sister, Yu Jianjia. After having blood extracted from her heart for three years, Yu Youyao’s life was nearing its end, so her wrist was slit and she died just like that.

Upon waking up, her heart thumped wildly and she decided to choose the first man she saw to escape that tragic fate. Thus, she clung onto the leg of her maternal cousin who had come all the way from the You Kingdom. “Cousin, I’ll be good to you for the rest of my life.”

Zhou Linghuai looked at the girl nestled in his arms. She had a lovely face and puppy eyes. Despite his usual ruthlessness, he suddenly found himself unable to reject her. And so, he became Yu Youyao’s protector, helping her to take revenge on those who bullied her, fend off the schemes of others, and reject all of her suitors. He even helped her attain glory and magnificence.

Once Yu Youyao reached adulthood, events started to progress according to her dream. The Marquis’s son, Song Mingzhao, had indeed come to request for her hand in marriage. However, Zhou Linghuai pressed Yu Youyao against the wall and said in a low voice, “You’re mine. You can’t marry anyone else!”
