I once sat and discussed with Newton, and I once walked side-by-side with Einstein. I messed up Planck's hair, and I even wrote a preface for Zhang Zhongjing's "Treatise on Febrile and Miscellaneous Diseases". In short, this is the story of a scholar traversing various times and spaces throughout history, using the wisdom of the ancients to open up the future of mankind. What? You say this is unscientific? No, this is very scientific! Note: This book is not a multi-world stream or an infinite stream, the protagonist will not have superpowers, you will find out as you read. There is also an old book "Handbook of Conquering Other Worlds" with a high completion rate of 30,000 and an average order of 8,000+, welcome to read.
