Datang: Build a Million Cavalry at the Beginning

Li Feng traveled back to the Tang Dynasty, awakened the system, and inherited his ancestral blacksmith shop. Just when Li Feng was about to show off his grand ambitions, he found that the system was really cheating! "Armed building system!" The name is domineering! What is provided is more domineering.

This is the prosperous age of Zhenguan! Li Feng had no choice but to lie down for the time being and continue to run the blacksmith shop, living a comfortable life.
