Qin Zhengfan unintentionally saved an old man, but unexpectedly, he was the spiritual cultivator guarding their planet, the supreme authority who had not been involved in the mundane affairs of Tianfeng Star for hundreds of years. Because Tianfeng Star's spiritual energy was thin and turbid, and the transmission gate was destroyed, the old man could only die on Tianfeng Star and could not return to the distant planet where his sect was located. Qin Zhengfan inherited the old man's mantle. In this way, a doctoral student who was about to graduate and become a university teacher became the supreme commander of a planet that had been forgotten by the times for five hundred years.
