Swallowed Star also know as Tunshi Xingkong, is a Chinese anime based on the web novel written by I Eat Tomatoes. An RR virus causes chaos on Earth, turning infected animals into monstrous attackers. To survive, humans build walls and cities as their last refuge. This period of struggle is referred to as the "Period of Nirvana." In this extreme environment, human abilities, including martial arts, improve and evolve. The most skilled among them are called Warriors, and Luo Feng, 18, aspires to become one. Just as he is about to take his college entrance exam and face a life-altering decision, a monster attack changes his path. The city is in danger, but the military is powerless, leaving only one soldier to maintain security.

Inspired by the soldier, Luo Feng decides to train as a fighter to protect his loved ones. His journey as a martial artist is not easy, as he must overcome outside influences and financial difficulties. Despite these challenges, Luo Feng continues to develop his skills and is recognized for his abilities. He joins other justice fighters to protect humanity from the monsters and ensure their survival. Will Luo Feng and the other soldiers be able to drive away the monsters and protect the human world in this desperate doomsday situation?
