On the top of Qingming Mountain, young Chen Fan has been raised by his master for eighteen years. He is ignorant and ignorant. He only knows the sun and moon in the mountain and does not know the prosperity of the world. With the master's orders, he packed his bags and went down the mountain to find the seven Qingguoqingcheng senior sisters who he had never met before but had long been talked about by his master. There are seven senior sisters, all of whom are unparalleled in splendor and power - the undefeated god of martial arts in the martial arts family, the turbulent queen in the business world, the peerless heavenly doctor who is a master of medicine, the talented woman who is astonishing in the literary world, the goddess of war who is the iron-blooded rose in the military world, the descendant of Guigu who is proficient in metaphysics, and the most beautiful queen in the entertainment industry. They were originally proud women in the world, cold and arrogant, but because of their master's instructions, they became extremely attached to this little junior brother who suddenly appeared, vying for his favor and protection, and bringing the best in the world to him.
While enjoying the ultimate pampering from his senior sisters, Chen Fan followed the clues left by his master to find the mystery of his life experience. He thought he was just an ordinary boy in the mountains, but he didn't know that every time he was in danger, the power hidden in his body would awaken. He could repel powerful enemies with a casual move, and reveal secrets with a casual word. It turns out that he is not an unknown person, but the heir of the lost ancient supreme bloodline, and the true king in charge of the ups and downs of the three realms.
From the initial dependence and closeness, to the spread of heartbeats as they get along day and night, the friendship between the young man and his senior sisters quietly fermented into a passionate love. Faced with many murderous intentions and conspiracies, Chen Fan joined hands with seven senior sisters to sweep the world with absolute strength and uncover the truth about his life experience. In the end, he and the seven senior sisters who were all-powerful to the country took charge of the prosperity of the prosperous age and wrote a unique love between the Supreme and the seven queens.
