I'm a cannon fodder supporting role, marrying the villain's eldest princess at the beginning

Luo Changge realized that she had transmigrated to a novel she had read before Stay Up Late.

Furthermore, he became the young sect master of the first second-rank sect to be destroyed by the hot shots in the novel?!

Fortunately, the necessary cheat for transmigrators appeared.

Luo Changge grinned. He accepted all the opportunities that belonged to the hot shots and even the female lead.

Moreover, relying on his familiarity with the plot in the book, Luo Changge chose to form an engagement with the Grand Princess of the Taiyue Empire, who was about to become the greatest villain in the Jiu Xuan Land in the future, and form an alliance to kill the hot shots!

In short, this was the story of the protagonist and the villain, the Eldest Princess, conquering the mainland together and killing the hot shots of various factions.
