In the process of development, every implementation of new technologies encounters resistance from old concepts, which makes them face a dilemma between interests and beliefs: whether to cater to the old aristocracy to become stronger quickly, or to stick to the bottom line and promote new technologies. At the same time, once the hidden identity of Li Dali's time traveler is exposed, it will trigger the pursuit of the old nobles.

They eventually changed the pattern of the times.
