Lords of All People: I Am the Only One Who Can Build a Mechanical Empire

In the era of national lords, Su Yang awakened the useless talent 'Heart of Metal'! But in his previous life, he was a weapon designer and an enhancement system, and he said that there was no better talent than this. While other lords were still training hard and worrying about life. But he drove around in the Gundam and lived a life without worries about food and clothing. It is impossible to practice cultivation. You can only make land super battleships and heat particle mushroom eggs to maintain your life. Many years later, when the world was afraid of him, Su Yang scratched his head and said: I just want to prove that Metal Heart is not a useless talent.
