My Servant Has a Doctorate in Engineering

What evil have I done! When other people traveled through time, they either started with Long Aotian or counterattacked with the annulment trend. I was better off. I almost starved to death at the beginning, managed to become a CEO, then crashed in the wilderness to survive, and even picked up a severely burned oil bottle! Was this the wrong script? Director! I want to change the script! Lin Xiao, a doctor of engineering mechanics from a modern 985 university, traveled to the "Tianxuan Realm" after working on his thesis all night. This is a different world where alchemy and martial arts coexist, but basic scientific theories are extremely backward. He cannot practice traditional martial arts, but he has strong spiritual power and can transform modern engineering, physics and chemistry knowledge into "truth alchemy". He can see through the structural weaknesses of matter and "enchant" it with scientific principles (for example: using the principle of a pressure cooker to make alchemy, using a lever and pulley set to disguise divine power).
