In 2187, the "Great Silence" event broke out - all human interstellar colonies suddenly lost contact, and the earth became an "isolated island" blocked by unknown civilization. Lin Ye, a mechanic in a wasteland city, accidentally activated the "Star Code" embedded in his own genes while repairing the black box of a crashed colonial ship - this is the "civilization fire" left to mankind by prehistoric alien civilization, and the only key to breaking the blockade.
As the code awakens, Lin Ye is not only able to communicate with out-of-control AI and mutated interstellar creatures, but also discovers that the truth of the "Great Silence" is far crueler than imagined: the "Watcher Civilization" that blocked the earth is actually a "civilization filter" created by prehistoric civilization, and mankind will soon be judged as "unqualified" due to its "self-destructive tendency" and will face complete elimination.
In order to save mankind, Lin Ye gathered the exiled interstellar captains, the rebellious AI consciousness, and the "Secret Keepers" group who mastered ancient technology, and broke through from the wasteland of the earth to the core of the galaxy. They not only have to fight against the mechanical legion of the Watchers and crack the "survival test" of interstellar civilization, but they also have to face betrayal and suspicion within humans - after all, not everyone is willing to believe in the "foreign code", and some even want to take it as their own and become the new "ruler of the universe."
