After Transmigrating to Peach Blossom Spring, I Became a Local Powerhouse

"Who are you? How did you come to our Peach Blossom Valley?" asked three men in unusual clothes, looking at the young man lying on the beach.

The young man, Yuan Yi, lay on the beach and gazed at the three men. Then he suddenly realized he had transmigrated and brought a spatial System with him. From then on, he used modern technology to help the people of Peach Blossom Valley improve their backward farming methods. He also helped the clan chief lead them down the path of collective farming, with great success, and eventually became a major power in the region. Soon after, the demonic cult, pirates, and all sorts of forces from the court came calling. Let's see how I break this deadlock.
