Walk into the unscientific
I sat with Isaac Newton and walked with Albert Einstein.
I have messed up Planck's hairstyle, and I have also proposed a preface to Zhang Zhongjing's "Treatise on Typhoid Fever and Miscellaneous Diseases".
All in all, this is a story of a scholar who shuttles through various time and space in ancient and modern China and foreign countries, and uses the wisdom of his predecessors to open the future of mankind.
What? You say it's not scientific?
No, it's scientific!
Note:
This book is not an infinite flow of heavens, and the protagonist will not be superpowered, so you will know it if you read it.
There is also an old book "Another World Conquest Manual" high-end 30000 are ordered 8000+, welcome to read.
