The social animal died suddenly at the age of thirty, and when he opened his eyes, he became the crippled and deposed prince Li Chengqian of the Zhenguan Dynasty. There is no system, no omniscient memory, just a bunch of bits and pieces of knowledge that have been misremembered and misremembered, and all the problems that cannot be changed: laziness, fear of trouble, lack of face, and extreme fear of death.
In order to survive, he used community experience to deal with the court, and used half-baked knowledge to come up with penicillin, cement, and steam engines. Along the way, he made mistakes, got into trouble, felt guilty, and grew up. From a selfish villain who just wanted to survive, he slowly took on the responsibility of his family, country, and people around him.
There are no cheating stories, just an ordinary person struggling, taking the Tang Dynasty with him, and starting a warm and clumsy industrial revolution with a smile.
