A Mysterious Fanfiction: The protagonist, Chen Yuan, a "broker," has been traveling through the Harry Potter world for seven years. He finally receives an offer to become a professor of Muggle Studies at Hogwarts, but upon waking, he finds himself transported to another world—this time, in the body of a woman. At the same time, the "Mysterious Queen" Bernadette awakens within Chen Yuan's body. PS: The male and female leads swap souls every few days. (The author has already completed the novel "A Mysterious Journey Begins with Harry Potter.")

The ancient sun god fell.

The betrayer ascended the throne.

The ingot was cast astray for the second time.

Is it sad to wake up as an elf in this era?

Even if it is not Gou Sanjia, can't the time traveler find a way to smuggle the ingot?

Good news, I got in due to a bug.

Bad news, I got stuck in the fifth era.

This is a story about a time traveler who advances in the fourth and fifth eras simultaneously.

The protagonist's life experience is relatively complicated. In the northern continent, he was a god, wore a crown, and was a great noble. In the western continent, he was a person who was in harmony with the Tao. In the future, he will attack God.

Also known as, the magical source castle helped me connect the two eras.

Also known as, it is a bit weird for the time traveler to encounter bugs in time and space, but in the writer's pen, this is reasonable.

Good news, I have traveled through time.

Bad news, I have traveled through time to a book I have never read.

What should I do?

By the way, I saw a video made by a book friend before traveling through time. Just follow the instructions in the video.

1. Assassin potions are more suitable for saving lives.

…

4. If you want to develop some hobbies, then buying an astronomical telescope to observe the starry sky is a good choice.

5. The official personnel in this world are very dangerous. They will treat you as a heretic and eliminate you. If you meet them, you must pick up the pistol beside you to protect yourself.

…

7. When you think that there is no hope for promotion, you can try to recite the honorable name of Amon, so that you can be sent to the angel.

8. If you encounter an unsolvable dilemma, you can shout Leodro to the sky, so that all problems will disappear.

…

Very good, first choose "Assassin", watch the starry sky with a telescope in your spare time, shoot directly when you meet the police, and then Leodro when you are in doubt, and Amon if you can't get promoted. The formula is directly in seconds.

Looking at the task list in his hand, Loen was very proud.

…

A long time later, Loen, who had become an angel, looked at the task list where nothing was completed and sighed.

How come I have accomplished nothing!

ps: This is mainly the plot in "Lord of Mysteries".
