Li Ju'an, who had many regrets in his previous life, was reborn in the 1980s.

In this life, his first love, Lin Mei, hadn't married yet, the land in the village hadn't been distributed to each household, his mother hadn't fallen seriously ill from the burden of the family, and his sister hadn't dropped out of school and been bullied.

To make up for the regrets of his past life, Li Ju'an decided to take the right path, relying on the land for survival, training dogs, setting traps, carrying guns, training hawks, and hunting to accumulate his first pot of gold.

Unexpectedly, his reputation in the mountains became more and more famous, he became a cannon head, and also found a 37-year-old iron lump, and became a brother to the nobles. After the new era came, he used his hands and foresight to severely discipline this barbaric era.
