In a remote frontier region, Lu Jiu, a young and exceptionally talented doctor, uses his medical skills and passion to bring hope and light to the local people. But an unexpected sudden death abruptly cuts his life short. It seems fate has not given up on him. When Lu Jiu opens his eyes again, he discovers that he has transmigrated to a world remarkably similar to Earth, but with a subtly different timeline, and become a newly graduated medical student.
The medical technology in this new world is closely connected to that of Earth from 2019 to the present, as Lu Jiu knows it, yet it also holds many unknowns and challenges. What shocks him even more is that he has awakened a mysterious entity called the Strongest Medical Assistant System. This System not only contains a database of all the medical knowledge he possessed in his previous life, but can also provide the optimal treatment plan based on real-world conditions and even predict how diseases will progress. It is as if this medical wonder was made just for him.
