Magic Defeats Magic

Li Yan, who holds a Ph. D. In physical chemistry, was hit by a truck because he pushed away a child in the middle of the road at a critical moment. After waking up, he found himself in a strange medieval-style magical world. He retained his original appearance - with a sparse beard and slightly messy hair, but lost all his identity credentials as a modern scholar. In this world, even street vendors can light cigarettes with a small flame on their fingertips, and farmers can tend their crops with a weak "vitalization technique." However, Li Yan is a complete "magic insulator". Faced with the contempt of others and the embarrassment of life, the only weapon he relied on to survive was the vast mathematical, physical and chemical knowledge in his mind. From using the lever principle and friction calculation to help the dwarf uncle build a more labor-saving forging hammer, to using chemical replacement reactions to extract precious metals from slag; from using Bernoulli's equation to improve the accuracy of wind magic apprentices by 300%, to constructing a classical mechanical model to solve the "ghost incident" of a noble family... He sheds the light of science into this world that relies on magic but knows it but doesn't know why. At the same time, he formed an adventure team with the elf girl Ella and the down-and-out knight Garris who talked about running things. They dealt with the arrogant magic aristocrats, solidified classes and the mysterious magic crystal trade. He used science to subvert the understanding of the world time and time again, and step by step he revealed the astonishing truth about his own time travel, the nature of the magic crystal, and even the connection between the two worlds.
