On the rainy month of the year 2075 in the Lunar Calendar, the Ailing Olan Palace urgently issued an imperial edict summoning young nobles from all over the country to enter the palace. From the prosperous imperial capital of Luofel to the distant border plains, from the huge Steely Desert to the mysterious Spiral Mountains, as long as they are young nobles aged ten to sixteen years old, no matter how far away the canonized territory is, they must rush to the palace as soon as possible. It is said that the purpose is to select the future pillars of the country from talented people.
However, just as King Ailing Olan's body was weakening day by day, the country's national power and the appeal of the palace were far less powerful than the king thought. Compared with the fish, rice, mineral deposits and wealth in their own territory, the nobles seem not to care too much about the future of the kingdom. While Yuyue's summons was being dragged through the blue moon, the flaming moon, the water moon... And it was almost moonless, there were still a large number of aristocratic youths of the right age living a prosperous and worry-free life at home, and it seemed they had no plans to set off.
So, one day in Shuiyue, the most exciting news since the victory of Thunderstorm Valley came out in the palace: King Ailing Olan will choose the heir of the kingdom from the noble youths gathered in the palace!
It seems that it is just an ordinary selection of the heir to the throne, but a huge conspiracy is hidden inside. What will happen to the young people who are tied together by the thread of fate?
