Qin Shihuang was reincarnated as "Zulong". What about "Black Dragon"?

The "five virtues" originated from the "five elements" theory of ancient ancestors, that is, gold, wood, water, fire and earth. According to Zou Yan's theory, the Zhou Dynasty was considered to have a "fire virtue". Therefore, according to the reasoning that the five elements complement each other and are mutually causal, it should be "water virtue" to replace the "fire virtue" in the Zhou Dynasty.

After Qin Shihuang unified China, he took the theory of "Five Virtues at the End" as a treasure, boasting that the Zhou Dynasty in Qin Dynasty was "water virtue" rather than "fire virtue" and "ordered by heaven". There is no doubt that his intention is to find a "theoretical basis" for regime change and make it an ideological tool for the Qin Dynasty to rule the people and consolidate the political power.

Qin Shihuang unified the six countries and claimed to be the first emperor, that is, "Zulong", so Zulong was his self-styled title, while the Black Dragon was due to Qin's water virtue, which was black, earth virtue was yellow, Jinde was white, Mude was green and fire virtue was red.

Is the Qin Dynasty water virtue or black? Therefore, Qin Shihuang's imperial clothes are mainly black.
