[Farming + multiple races + demon race + lord + demon king + invincible]
Top assassin Nuo Chen treated killing as an art, then found life so dull he “killed himself.” Reborn as the lord of Haiyin City on the kingdom's remote frontier, he faces oppression from a decaying dynasty and the rising tide of the demon race. He rejects the common pursuit of power and strength: the kingdom's crown is nothing but tarnished gold, and even invincible power is only fit to be tested against the iron cavalry under his command. When the demon race reaches out in partnership, he turns around and betrays the empire.
