The following are some novels in which the female lead saved her father: - "Working Rules of the Ministry of Justice": The female protagonist, a modern lawyer, transmigrated to ancient times and became the daughter of a small tea merchant. Her father was implicated in the tribute tea case and was imprisoned. The female protagonist came all the way from Huzhou to the capital alone to save her father. She looked for opportunities to visit the prison at the gate of the Ministry of Justice. Later, in the process of searching for the truth, she had many interactions with the male protagonist and others. - "Did Miss Zhu fall into a trap today?" The female protagonist's father was involved in the witchcraft case and went to prison. The female protagonist actively dealt with various situations to save her father. Later, she brought her family to the capital and walked a different path, growing up in the ups and downs of officialdom. - "Canglan Path": The female protagonist's entire family was trapped and imprisoned by the male protagonist. Her father was forced to die by the male protagonist. Although the female protagonist did not directly start to save her father (because her father was already dead), the female protagonist began a series of plans to take revenge on the male protagonist. The root of revenge also stemmed from her father's encounter. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The survival crisis in different novels had different beginnings: - In doomsday crisis novels such as " Heavy Trucks in the Apocalypse "," Real Doomsday Game "," Final Abyss "," Global Evolution ", and " Dark Blood Age ", survival crises were often brought about by doomsday environments. For example, the main character's cell phone in " Real Doomsday Game " was implanted with doomsday systems and faced with doomsday in various parallel worlds. These doomsday could spread to reality, and there was a black hand behind it. The protagonist of Final Abyss was in a world adapted from the story of the battle royale. Only one out of 100 people could survive. This was the survival crisis that the protagonist faced. - In infinite novels such as " I, the System Style Protagonist, Joins the Chat Group ", the protagonist faced crises in various infinite worlds. For example, the protagonist of Crisis Management Game faced various public crises in the game and needed to possess a specific person to solve the crisis. There was also a death replay and a total time limit. - In " King of the Island," the protagonist's cruise ship was wrecked on a deserted island. He faced the survival crisis brought by the deserted island environment, such as food acquisition, shelter from the wind and rain, and other survivors were still struggling with these basic needs. This was the beginning of the protagonist's survival crisis. - In " The Legend of the African Lion 1," two lionesses, Maggie and Camily, were born thin and weak and often bullied. The survival rules of the grassland forced them to become strong in order to be recognized. This was the survival crisis they faced at the beginning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
