From a Mortal Bandit to an Immortal Emperor

I know from afar that the immortals, Buddhas and saints all come from mortal world. Who says immortality is irreversible? Who am I? I am Tang Chuan, with a broken system, expanding martial arts, ruling the common people, establishing an immortal dynasty, resisting foreign races, step by step from a mortal to an immortal emperor. The ancestral court of humanity has been decayed for thousands of years, and I am actually willing to send my compatriots to be the blood food of aliens? Behind the peaceful human territory is actually a breeding ground for demons. Since the human race has no emperor, I will be the first emperor and create a prosperous age of mine. This is the legend of Tang Chuan. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
