Liang Jun transmigrates to a parallel world and joins an Arctic research team. His mission is to guard the barren Arctic research base and improve its systems. A rescued polar bear expresses its liking for your fish, and the system rewards you with an Arctic gift pack. The white wolf king thinks you've taken good care of his cubs, and the system rewards you with 10 reindeer meat. An orca thanks you for removing barnacles, expressing its love for you, increasing your affinity by 100. Feeding a seal pup earns you the love of the entire seal family, and they gift you fishing gear. Helping a baby sea turtle return to the ocean earns you the turtle's praise, and they gift you equipment. An extinct Arctic penguin brings you a beautiful wife, announcing you're going to be a grandfather. ... Liang Jun farms and builds infrastructure at the Arctic research base, transforming the previously abandoned Base 1834 into a supply paradise that every research team detours to pass through!

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.
