Wang Yi had just transmigrated when he experienced being cheated on, going through a divorce, and being kicked out of his home. These were events faced by a useless male character.

However, he soon discovered that this world seemed out of sorts. There were martial arts grandmasters and martial arts clans?

Fortunately, he activated the Martial Arts Sign In System.

[You have successfully signed in and obtained the Dragon Elephant Wisdom Technique. Please cultivate according to the instructions.]

Thus, Wang Yi kept signing in until he leveled up and became a martial arts grandmaster. After that, he discovered the truth behind his wife’s affair.

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.

Gong Yu, a three-good student who entered the unknown world for no reason, became a sick and poor little Highness who disguised herself as a man.

In line with the principle of hard work and progress, I work hard to be a two-headed grass and survive in a mixed court.

However, she accidentally picked up the handkerchief of the future queen and sister, and returned it with the good character of picking up gold.

The result was a series of such rumors.

Since the love is compatible, the two are in love, and they are secretly in love, why not choose another day to get married?

Gong Yu herself expressed panic, but the queen sister actually acquiesced.
