Why didn't the seven generations of monarchs after the founding of Qin do anything?

In the 12th year of "xianggong", Qin Xianggong was killed in the battle with Xirong and buried in Qishan. So his son Wen Gong succeeded to the throne. Duke Wen used to live in Xiqiao Palace, but he didn't follow the rules. He lives a leisurely life all day and doesn't like hunting and traveling. Jin Wengong hunted for four years and came to the junction of Yishui and Weishui. Seeing the beautiful scenery, he decided to move the capital here. Ministers objected, so he made a divination and blocked everyone's mouth. After I came, I just settled down, and in a few years, I will build a building dedicated to heaven and earth. From then on, I began to do a good job in economic construction, and the results were not bad. There was a battle with Xirong in the middle, and I won. I got the land, and I actually gave it all to Zhou. I really have to admire this man's "loyalty"! Since then, Wen Gong has been silent.

Wen Gong pampered himself all day and lived for a long time. He executed his son, but he didn't die. It was not until Wen Gong was fifty years old that he died of illness. To his grandson Ning Gong.

Ning Gong was only ten years old when he ascended the throne. This child who knew nothing was played around like a puppet. When I grow up, I have the right. I fought several wars with Xirong and won them all. Finally, I swept the party. Originally, Ning Gong was a monarch who could make great achievements, but his life span was too short and he died at the age of 22 (good health is the capital of success). I hanged myself too soon and didn't solve the problem, so the ministers quarreled about who would inherit the throne. Ning Gong has three sons, Wu Gong, Degong and Zi Chu.

First of all, my aunt refused to let the Prince of Wu Palace succeed to the throne, but instead set up a five-year-old son. After six years in power, he was only 1 1 years old. He was killed by his sister-in-law's third father, who established the original son of heaven, Wu Gong, to inherit him. Wu Gong also has some means. Later, he killed the oldest concubine and gained real power. After twenty years in office, he also fought against Xirong all day. Although he won many battles and lost few, he still lacked strength and failed to achieve much.

After Wu Gong's death, Li Di De Gong succeeded to the throne. After two years in office, Degong went. Degong also has three sons, namely Gong Xuan, Success and Mu Gong. The same is true of these three people. After their death, they had no sons, so they all made their younger brother king. Gong Xuan was in office for 12 years, and when he was a public official for 4 years, he spread to Mu Gong, and then started the ZTE era.

From Xiang Gong to Mu Gong, for more than 100 years, the state of Qin was either fighting for power or Xirong, and the struggle was illegal, and there was not much oil and water for each other. Those who live long without ambition die young with ambition. So after so many years, Qin is still the original Qin. It can be seen that in the feudal era, the ambition of a monarch decided the direction of this country. The monarch is talented, and the country is prosperous. If a few useless guys come one after another, even a good family can be destroyed.
