Modern young man Lin Huaizhen (meaning "Embracing the Truth") travels to the parallel Republic of China in 1920. The historical trajectory here is similar to reality, but the fate of historical celebrities is very different. He is responsible for the "Civilization Lighthouse System", and his mission is to prevent Chinese civilization from falling deeper into darkness in troubled times. The system will not directly grant invincible power, but will obtain "civilization points" through knowledge, idea dissemination and achievements, which can be used to unlock specific technical blueprints, gain insight into the loyalty of others, or temporarily strengthen team capabilities.
