Conquer the Heavens, Starting with the Chaos Pearl

What? All eight of my brothers are emperors famous throughout history: my eldest brother is Yin Shang, my second brother is Ying Zheng, my third brother is Liu Bang, my fourth brother is Yang Guang, my fifth brother is Li Shimin, and my sixth brother is Zhu Di… I never expected to transmigrate into a world where everything had fused together. The Central Domain is the Great Xia Dynasty, the Western Domain is the fantasy world from my previous life, the Eastern Domain is the historical world from my previous life, the Northern Domain is a world of immortal heroes, and the Southern Domain is a world where martial arts universes converge.
