Yaxin, who came from another world, entered the world of "Spicy Metamorphosis" under the leadership of the time-travel system 047, and became close friends with the fighting genius Guan Xiaodi, becoming the "group pet" cared for by everyone.
In the training camp, they experienced rigorous training such as a ten-kilometer run with heavy loads, fire water column resistance, and mud endurance challenges. They also encountered provocations from unruly "thorn-headed" trainees. Yaxin always unites the team with gentleness and wisdom, Guan Xiaodi protects his companions with courage, Cui Tianqi shines in the field of brainpower, and everyone gradually grows up through sweat and running-in. Although Liu Sha and Qin Sheng appear stern, they silently take care of the students in every detail. They especially pay special attention to Yaxin, which adds a subtle color to the intense training life. As the training deepens, the secret of Guan Xiaodi's life experience and the story behind the Fiery Military Academy gradually emerge. A group of young people with dreams are completing their own "transformation" in the tempering of Fiery Fire, and are moving forward firmly towards the goal of qualified bodyguards.
