the world is a narrow bridge novel

I'm not sure specifically as I haven't read this novel. It could be about the idea that life in the world is like walking on a narrow bridge, full of challenges and precariousness.

Since I haven't read the novel, it's difficult to say. But perhaps there is a character who is at the forefront of the story, a person who is constantly facing the challenges of this 'narrow bridge' world. There might also be secondary characters who either help or hinder the main character's journey on this metaphorical bridge.

As for which one was easier to raise, Narrow Bridge, Ink Egg, or Sarwen, he had to consider it from many aspects. From the perspective of the breeding environment, these three types of turtles belonged to the larger species of egg turtles. Some people believed that egg turtles were suitable to be raised in tanks. These three kinds of turtles needed to provide suitable space when they were raised in tanks, and because they were larger, they would have higher requirements for space as they grew. From a mixed breeding point of view, turtles like Narrow Bridge, Sarwen, and Ink Egg could not be mixed with other turtles because even if they had the same living habits, they had fierce temperaments. Mixed breeding might hurt other turtles. From the perspective of feeding, there was no clear data that showed that these three types of turtles had a particularly large difference in food requirements. However, there were turtle foods suitable for these types of turtles on the market, such as egg turtle food. In terms of growth habits, Salwen was big and had a cute rosacea nose, so he could be raised in groups. However, Salwen was only suitable to be raised in groups if he was less than 12 centimeters tall. The ink eggs were good at swimming. When the seedlings were bigger, they could gradually deepen the water level. In the south, where the winter temperature was not very low, the physically strong and larger ink eggs might survive the winter. However, the temperature in the north was low, and it was best to raise them with heating during the long winter. Moreover, ink eggs liked to bite on electrical wires and other items, so they needed to pay attention to protection when heating. There was no particularly unique growth habit about the narrow bridge, which indicated that it was significantly different from the other two in terms of difficulty in raising it. In general, it was difficult to determine which one was easier to raise, Narrow Bridge, Ink Egg, or Sarwen. It depended on the environment, experience, and resources that the breeder could provide.
