There Is a Northern Song Dynasty in My Sand Table

Li Yi suddenly discovered that his Penglai-themed sand table had mutated! It is also connected to a Northern Song Dynasty that was reduced a hundred times! When he discovered that plastic dolls could also be animated, he turned to look at the pile of hand-made dolls he had made and fell into deep thought! After that, Li Yi used the name of Penglai Immortal to give the Northern Song Dynasty some crazy technology! The same technology is used to build a most common machine tool inside, and its processing accuracy is at the nanometer level outside. Just rub a big iron plate and it will look like a chip! … Ever since, Li Yi used technology to "package" Penglai in the sandbox and develop a different world! In reality, a mysterious high-tech company is packaged and sells batches of products that are comparable to black technology!
