Travel Back to the 70S: I Forge Black Technology by Forging Iron

[Era + Industrial Upgrading + Black Technology + System + Serving the Country] Li Rui, a top mechanical engineer, was unexpectedly reborn in the late 1970s when supplies were scarce and technology was backward, and he became a young worker assigned to a remote machinery factory. Faced with outdated equipment and backward production technology, he thought he would be buried for the rest of his life, but he accidentally activated the [Labor Creative System]! As long as you work hard, you can earn creative points, exchange them for future black technology blueprints, and even unlock the mysterious "Laser Electromagnetic Cannon"! Starting from transforming an old lathe, to optimizing the steelmaking process, and then to conquering cutting-edge materials, Li Rui used his hands and wisdom to turn a small factory on the verge of bankruptcy into an industrial giant. While the Western powers are still laughing at us for saying "Buying is worse than building", Li Rui has quietly built fortresses of the future, making the world tremble!
