Liu Guangqi was originally a modern professor in the field of mechanical engineering. After an experimental accident, when he opened his eyes again, he actually traveled to the world of the courtyard full of love and became Liu Haizhong's eldest son. He is familiar with the original plot, and also knows the nature and future direction of everyone in the courtyard. Liu Guangqi in the original work studied in a technical secondary school and eventually left his hometown to become a son-in-law, which was a sad result. Now that he is here, he will never make the same mistakes again! So he decisively gave up technical secondary school, sprinted for the college entrance examination, and successfully entered the Department of Mechanical Engineering of Tsinghua University, becoming a proud man of the times! A few years later, Liu Guangqi graduated from university and joined the Ministry of Machinery Industry as soon as he graduated! When the deaf old lady, Yi Zhonghai, Silly Zhu and others were still scheming and plotting against each other in the courtyard. Liu Guangqi is no longer on the same level as them. Beast? Just ants! Not worth mentioning! See how Liu Guangqi is making progress step by step in this era and reaches the top!
