In the interstellar age, Yi Chen falls from a celebrated security officer to a prisoner, all because he accidentally shot and killed a rebel. After two years in prison, he thinks his life holds nothing but bars and longing, until the mysterious Zhao Kun appears and draws him into a world that overturns everything he knows: the Star Core Squad, spacetime rifts, Star Core secret realms, and powerful mechs.
Joining the squad and activating the Star Core Mech System gives Yi Chen a chance to regain his freedom, while also saddling him with the responsibility of protecting the stars. Paired with the nimble and capable mech operator Han Yue, he pilots his personal mech, Prison Breaker, deep into the perilous Star Core secret realms to fight hidden dark forces.
The truth behind his comrades' deaths, his family's safety, and the secret dangers lurking among the stars: under pressure from every side, Yi Chen relies on his unwavering resolve and the System's help to grow from a prisoner into a top mech warrior. On an interstellar battlefield where science fiction technology meets fantastical energy, he will break free of his chains, wield his mech as a blade and the star core as his soul, and write his own thrilling legend.
