Daqin: Ancestral Dragon Protector, Creating a Mythical Heaven

Qin Xuan traveled through the pre-Qin Dynasty, transformed into the totem of the Great Qin's national destiny, the black bird, and bound it to the mythical destiny system. It happened that Ying Zheng suffered humiliation in Handan when he was young, and a drop of the emperor's blood awakened Qin Xuan. In order to live forever, Qin Xuan decided to build Da Qin into the supreme mythical heaven behind the scenes! He casually threw out the "Human Emperor's Prison Suppressing Technique" and began to cultivate the Great Qin Immortal Cultivation Army. Many years later, the six-nation coalition forces united and a million troops came to Hangu Pass. I thought it was a confrontation with cold weapons, but the city gate was opened wide—— Wang Jian crossed the sky and cut off the torrent of thousands of feet with a knife; Meng Tian condensed the Dharma and teared the sky with thunder in his hand; millions of black-armored troops came out with swords, covering the sky and the sun! The kings of the Six Kingdoms were so frightened that they peed on the spot: "Didn't we agree that we should all practice martial arts together to fight for hegemony? How come all the members of your Great Qin have become immortals?" The coming of heaven in an attempt to eliminate the variables, Ying Zheng pulled out the Tai'a sword and pointed it at the sky: "Master said, there is no heaven above the territory of the Qin Dynasty!"
