Traveling through troubled times, he fled with his stepson

A dazzling ray of light cut through the darkness, and the young Lu Yu's consciousness seemed to awaken from a long sleep. He found himself in an ancient castle, surrounded by medieval-style decorations, with a blazing fire in the fireplace, casting swaying shadows.

Lu Yu was an ordinary librarian, and was shocked by the incredible phenomenon of time travel. He quickly looked at himself and found that he was wearing a simple linen robe and there were rough stone slabs under his feet. He tried to recall the scene before the time travel, but it was only a blur.

"Welcome to Heilsenburg, traveler." A deep voice broke the silence.

Lu Yu turned around and saw a burly man in armor standing at the gate of the castle, holding a long sword that was shining with cold light. "Who are you?" Lu Yu asked hesitantly.

"I'm Cassel, the captain of the guard of Helsenburg. You have been chosen, join us and become a member of the protection of the castle." Cassel's tone left no room for Lu Yu to refuse.

Lu Yu was full of doubts and curiosity, but he understood that surviving in this world was his top priority. He nodded and accepted Cassel's invitation.

Lu Yu followed Cassel to gain a deeper understanding of the structure of Helsenburg, and at the same time he began to realize that he had a special ability - the ability to sense the approach of each "transfer". This "transfer" seemed to be very similar to the infinite flow time-travel novels he read in the library, shuttling between different worlds.

At a dinner party, Lu Yu accidentally rescued a mysterious woman named Irene who was in danger of assassination. In return, Irene revealed the existence of a secret organization that studies and controls the "gates" that travel through various worlds.

Lu Yu's heart moved, maybe through this organization, he can find clues to go home. He decided to join the organization, and soon he learned that each world has its own unique rules and challenges, and the competition between members is equally fierce.

Under Irene's guidance, Lu Yu learned how to use his special abilities more effectively, and began to travel between worlds, gaining knowledge and honing his skills.

As Lu Yu experiences various worlds, he gradually discovers that there seems to be an important secret hidden in his memory, which is closely related to the truth behind the time travel. He begins to try to dig out these memories, while also pursuing a mysterious world called "Youjie", where it is said that all the answers are hidden.

During an adventure, Lu Yu finally faced his past. It turned out that he was an excellent space-time manager in the "ghost world". An accident caused him to lose his memory and drift into a different world.

Faced with his former identity, Lu Yu was faced with a choice: should he return to the familiar "ghost world" to resume his original life, or continue to explore the infinite world and find his true self?

Lu Yu's decision will echo in countless worlds, and his journey will never end, because in this vast universe, every choice is a new beginning.

"Time Traveler" is just the beginning of Lu Yu's story. His every step and every decision will write a new chapter in the infinite story flow. OK, here is the novel fragment generated according to your requirements:

Li Chuanfeng is an ordinary young man, living in an ordinary world, until that stormy night, when his whole world turned upside down. When he opened an ancient novel called "Bright Future" and prepared to read it, he was sucked into the book by a mysterious force in the thunder and lightning. When he woke up, he found himself becoming the villain in the novel who was destined to be defeated by the protagonist - Sikong Zhaixing.

Realizing the fate of his character, Li Chuanfeng fell into confusion and panic. But he quickly calmed down and decided not to act according to the original book. He began to try to change, first of all, his image, from the original arrogant and rampant to humble and restrained.

When he met the protagonist of the novel, Chen Ping'an, by chance, he deliberately avoided the conflict that should have occurred and even lent a helping hand to the injured Chen Ping'an, which led to the subtle seeds of friendship between the two.

As the plot develops, Li Chuanfeng understands the rules of the novel world more and more, and finds ways to avoid tragic fate. He uses his wisdom and modern knowledge to help people in the rivers and lakes solve many problems, and his reputation gradually improves.

At the same time, he carefully handled his relationship with the protagonist Chen Pingan, avoiding the direct conflicts described in the original work, and even secretly helped Chen Pingan overcome difficulties many times, winning Chen Pingan's trust and friendship.

Just when Li Chuanfeng thought he had completely changed the ending of the original novel, the story reached its climax. It turned out that the author of the novel had set up multiple possible endings, and each choice had to face different challenges.

At the most critical moment, Li Chuanfeng chose to sacrifice himself to protect Chen Pingan. This behavior moved all readers and triggered a certain mechanism in the novel world, allowing him to transform from a notorious villain to a true hero.

In the end, Li Chuanfeng did not die as set in the original novel, but remained in the world of the novel with a brand new identity and image. His story did not end, but opened a new chapter, continuing to find his own path in a world of countless possibilities.

Between time travel and rebirth, Li Chuanfeng finally understood that no matter in which world, no matter whether he is a decent or villain, the most important thing is to stick to his own morals and beliefs, and use actions to influence and change the world around him. In the world of novels, how Li Chuanfeng uses modern knowledge to change the original story trajectory and influence the social structure of the novel world is a topic worthy of in-depth discussion. The following are specific practical methods. Li Chuanfeng can also learn from the popularity and openness of modern education and advocate universal education, especially for the grassroots people and women. By educating people to read and write, imparting basic scientific knowledge and thinking skills, the cultural and economic structure of society can be gradually changed in the long run. In addition, advocating gender equality and increasing society's respect for women and recognition of their rights is a revolutionary change in ancient society.

Although materials and resources were limited in ancient times, Li Chuanfeng could use simple knowledge of physics and chemistry to promote some basic technological innovations, such as improving water conservancy facilities, designing more efficient mills and agricultural tools, and even trying to make basic glass and simple medical equipment.

Through these specific methods, Li Chuanfeng can not only effectively change the fate of his own villain in the world of the novel, but also actively influence and improve the technological level and social structure of the entire novel world, becoming a key figure who actively changes the course of history. This kind of innovation and breakthrough in action also makes the plot of the entire novel richer and more fascinating.
