As an "immortal", Ling Tian has risen and fallen in the thousands of years of Chinese civilization.
* He used historical knowledge, vision beyond the times and wisdom brought by longevity to play key roles in different dynasties (counselor, hermit, craftsman, physician, general, and even mysterious alchemist, etc.).
* The core main line is **"Assist the real dragon, stabilize the country, and promote civilization"**. He selectively intervened in history, not directly becoming an emperor, but looking for and assisting those "destined emperors" (such as Qi, Shaokang, Shang Tang, Zhou Wenwu, Qin Shihuang, Han Gaozu, Tang Taizong, Ming Taizu, etc.) Who were in line with the historical trend and had the potential to create or stabilize a prosperous age and promote civilization and progress. He helped them overcome key crises and ascend to the position of the Ninth Five-Year Plan, and guided them to implement benevolent governance, develop production, and promote integration as much as possible.
* What runs throughout is Ling Tian's thinking and struggle on "the meaning of immortality", "historical responsibility", and "changes in human nature".
