There Is a Wormhole in My House That Connects to Alien Planets

A wormhole suddenly appears in the home of Lin Feng, a young man living alone, which can lead to alien planets. The alien planet is exactly the same as the Earth's Paleolithic Age. Lin Feng named the alien planet Blue Star. When Lin Feng is on Earth, time on Blue Star tends to stop; when Lin Feng is on Blue Star, time on Earth tends to stop. Lin Feng decided to spend his whole life developing Blue Star's technology to see how far he could develop Blue Star's technology. After Lin Feng stayed at Blue Star for more than ten years, he found that he had no signs of aging. Lin Feng suspected that he would only be affected by Earth's time and not Blue Star's time. Therefore, Lin Feng changed his goal and prepared to see how long it would take to develop Blue Star's technology to a level similar to that of Earth.
