In the Galactic Alliance in 3025, {Ling Xiao}, a boy from the earth's slums, accidentally picked up the "Interstellar Mecha Core". This core can transform the mecha and improve its control. You only need to kill the interstellar beasts and complete the mission to obtain the "Energy Crystal Core" to upgrade. He transformed a dilapidated mecha and participated in the selection of the Star Mecha Academy, but was made things difficult by his mentor Duke and ridiculed by his opponents.
With the talent given by the core, Ling Xiao repeatedly slapped his opponents in the face, and even met Xia Mo, the top student in the academy, during an interstellar mission, and the two teamed up to fight against strange beasts. As he gradually emerged, he discovered that his parents were sacrificed in the Zerg war and were related to Karen, the leader of the Black Crow Legion. From winning the mecha competition to leading the team against the Zerg, Ling Xiao used the mecha as a blade and vowed to become a top mecha master, avenge his parents and protect the earth. Little did he know that Karen had already defected to the Zerg and was coveting his mecha core...
