I Was Reborn and Sold Arms in the Tang Dynasty

As soon as Li Yan, a military industrialist, opened his eyes, he became a poor household at the bottom of Chang'an in the Tang Dynasty. A prosperous age in the history books? It's all bubbles! The court hall was in a state of intoxication, and the barbarian generals in northern Xinjiang were sharpening their swords. Eleven years later, there would be blood and fire.
