Siheyuan: I, Mr. Liu, Will Join the Ministry After Graduation!

[Siheyuan + no system + fetal penetration ➕ having parents but short lives ➕ farming ] I, a doctor of mechanics in the 21st century, woke up and became the eldest son of the Liu family in the courtyard world. Babies with past life memories are invincible even without a system! He entered school at the age of five, was admitted to the Harbin Military Industry at the age of fourteen, and became the youngest outstanding graduate at the age of nineteen! Stay in school to teach? Impossible! Work in a factory? Even more impossible! The moment I got my appointment letter from the Ministry of Machinery. I, Liu Guangqi, am destined to take a different path from others! A road to the sky! Straight to heaven!
