Legend of Immortals and Demons in Sui and Tang Dynasties

Li Chang traveled to 617, the eve of Li Yuan's revolt, and became the younger brother of a military god. However, he discovered that this was no ordinary Sui and Tang Dynasties. He watched his brother fight in his inner energy armor, watched the water demon in the clouds control the wind and rain, and then looked at the third eye between his eyebrows in the mirror. He sighed, "Okay, it seems like this is the fairy-demon version of the Sui and Tang Dynasties."
