Galaxy History, I, Ying Zheng

I, Lin Feng, became the last Qi practitioner in the Qin Dynasty, and I wanted to fish until I grow old. But he picked up a young man in trouble who called himself "Zhao Zheng" by the river. I taught him how to practice Qi and strengthen his body, predicted his future, and boasted about the grand scene of the fairyland in my dream where "everyone is like a dragon". His eyes lit up when he heard it, and he high-fived me and said, "Sir, let's make it happen together." Until he was crowned with dragon robes, ascended the throne in Xianyang Palace, and looked down at me: "Lin Feng, I am the emperor, and I will accompany you to build the fairyland in your dreams." I looked behind him at the black dragon that was formed by the fate of the Qin Dynasty and covered the sky, and I fell into deep thought. How did the agreed-upon historical script turn into a mythical version?
