There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.

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.
