Interstellar Sign-In: I Really Just Want to Be a Salty Fish

Story summary: Lin Mo, a salty fish college student from the 21st century, traveled to the era of interstellar war and became an ordinary logistics soldier. When he was despairing about the future, he accidentally activated the "God-level Sign-in System". As long as he signed in at a special place, he could get various magical rewards. In order to survive and live a stable life in the cruel war, Lin Mo began to experiment crazily on the verge of death, checking in at dangerous locations such as battleship engine rooms, meteorite belts, and Zerg lairs, and acquired countless skills and black technologies. He originally wanted to keep a low profile, but he always inadvertently used system rewards to solve fatal crises. He was misunderstood by his comrades as a "koi" and a hidden master. Lin Mo gradually found a sense of belonging while getting along with the Iceberg Captain Qin Yue, the genius girl Su Xiaomi, the hot-blooded brother Fatty Wang and others. As the Zerg offensive intensified and mankind faced annihilation, Lin Mo finally stopped hiding and stepped forward in a god-level mecha rewarded by the system. He walked from behind the scenes to the stage, leading mankind to blow the clarion call for counterattack, ultimately destroying the Zerg master and saving civilization.
