This Time Traveler Is a Bit Strong

My name is Roland, I don't know my hobbies, but I habitually read all kinds of messy books and store a lot of strange ideas in my mind. I am also a physical education teacher who died suddenly because he stayed up late to grade math papers. In the next period of time, I will lead the people of another world in this world with highly developed magic civilization... Strengthen the construction of economic civilization! Enhance your living standards! Improve your ideological realm! Together we can achieve the three core policies of eating well, dressing well, and sleeping well, and finally lead the whole people towards a well-off life!
