After reading through Luo Fu's life experiences.
Li Hao finally understood where those strange devices and contraptions he saw at the beginning came from.
If the Immortals didn't lack safety and food requirements, given Luo Fu's "Inventor Attributes," the Central Plains would certainly have already entered a unique new age of civilization.
