Su Chen transmigrates into an interstellar mecha academy and becomes an unnoticed nobody. His mecha piloting is terrible, the elites mock him, the instructors look down on him, and even his right to remain at the academy is hanging by a thread. Just as he is on the verge of being expelled, he binds himself to the Ancient Spark System. It can draw on his memories of the Transformers from Earth and turn them into mecha transformation abilities. Absorb Spark energy, and he can level up.
When Void bugs attack the academy, low-level scouts run rampant and the elites are powerless to stop them. Su Chen uses the Spark System to unlock a basic transforming mecha, achieves instant fame in battle, and gets sweet face-slapping revenge on everyone who scorned him, completing his campus comeback. After leaving the academy, he joins an interstellar mecha squad and faces a double threat from space raiders and a vanguard force of bugs. With his upgraded combination-transforming mecha, he leads the squad out of danger and becomes a core fighter in the human coalition.
As the bug hive-mother arrives and the universe teeters on the brink of destruction, Su Chen gradually uncovers the truth: the Spark System is a legacy of an ancient Spark civilization, the bugs are a destructive race born of void energy, and his transmigration was itself the choice of the Spark civilization. He must not only fight the bug hive-mother, but also overcome the danger of the System turning against him and the interference of rebellious Spark wielders.
From an unnoticed nobody at the academy to an interstellar warrior and finally a guardian of the Spark civilization, Su Chen unlocks the ultimate combination-transforming mecha and unites the various races of the stars to defend civilization. Packed with thrilling mecha transformations and intense battles against the bugs, the story delivers both the exhilaration of an individual comeback and the epic stakes of civilization's survival. A battle to protect the universe is about to begin!
