Li Zhe, a "social animal" reserve student at the modern 985 University, was unexpectedly reborn as Tang Xuanzong Li Chen (Note: Historically known as "Little Taizong", but he often pretended to be stupid and kept a low profile before he ascended the throne), and found that this Tang Dynasty was inconsistent with the history he knew. In order to survive in the crisis-ridden palace and regain the modern salty life, he had to use the "hard core" of modern knowledge to govern the country, which triggered a series of ridiculous events and ultimately created an unprecedented prosperous age.
