Travel Through Ancient Times? on the Importance of Learning Mathematics, Physics and Chemistry Well

When I woke up, Newton's coffin board couldn't hold it down at first! Lin Xiao, a man from science and engineering in the 21st century, likes to mention the most "cheating" time travel in history - no system, no space, no identity. The starting equipment is only a pair of pajamas and a head full of mathematics, physics and chemistry knowledge. Others have traveled through princes and generals, but he started in the barren mountains, relying on the principle of leverage to build a shack and chemical equations to light a fire and cook. To survive, you must first learn about science! I wanted to be a small rich man and be content, but my strength (knowledge) didn't allow it! Treat illnesses and save lives? Bacterial disinfection VS magic water dance, the onlookers were shocked: "Doctor Lin, is the magic water really not as good as your salt water?" Get rich? Fermentation to enhance freshness, oil saponification, small workshop products are popular in the town! "Monster's Workshop" has peers kneeling in (and placing orders). Class opening? Gewu Academy specializes in "weirds": the accountant who is a master of abacus, the carpenter's son who is obsessed with smoking experiments, the cook's daughter who treats the kitchen as a battlefield... Daily class: Is the earth round? Students are worried "What should I do if I fall?"; Do chemical experiments? The classroom turns into a large-scale magic (and small explosion) scene in seconds! The old masters were heartbroken and said: "This man has misled his disciples!" However, when the bandits attack—— Physical traps + chemical smoke bombs teach them to be human again! When a severe drought comes—— Geological exploration + rainbow attracts water to irrigate tens of thousands of acres of fertile farmland! When the epidemic rages—— Microbial theory + disinfection and isolation save lives in the city! Lin Xiao proved with practical actions: if you learn mathematics, physics and chemistry well, you can really cheat by traveling through ancient times!
