With the Goddess’ blessing, he became a 『Divine Knight』 and founded an Empire.
As time passed, he grows older, and by the time the heavens called for him to come, the Goddess showed before him, asking for his last wish.

He wished to be reincarnated in the future.
He dedicated all his life for his people, he had no time to master his own arts.
This time, he wishes to live for himself, forging his body to the utmost limit.

The Goddess complied with his wish.
In the far future, the King shall reincarnate as the 『daughter』 of a renowned Knight family.
And, under some circumstances, she is labeled as a failure of a Knight, however——

「How convenient. I can stand on the foremost line without needing any rank. No better training than actual combat!」

Thus, the legend of the world’s strongest, most beautiful Knight Disciple (♀) has begun—

Thirty-six [sequences] rule the world, and the creatures who hold the [sequences] can move mountains, cut rivers, cover the sun with one eye, and enter dreams for thousands of years.

There are heroic wine immortals who master the [Wine Sequence] and walk freely, there are court princes who understand the [Law Sequence] to formulate laws, there are [Tao Sequence] Taoist priests in the mountains, there are [Gu Sequence] wild Gu masters, there are [Gu Sequence] Love Sequence] the stunner and beauty.

Waking up from a dream, for Chen Yuyan, the rivers and lakes are no longer the rivers and lakes in the game “Strange Rivers and Lakes”, but the real world that is vividly presented before him.

In order to survive, in order to get rid of the gaze of the “fairy god”, Chen Yuyan had to step into the rivers and lakes, facing conspiracy, swords, swords and shadows, and ulterior motives.
