Grandmaster of Martial Arts

When I wake up, the world has changed. The familiar place of mathematics, physics, chemistry, politics and history has become martial arts theory and martial arts practice. The strong man's Qi and blood control the mountains and rivers, and kill demons. The weak are restricted everywhere, whether in business or politics. And I, Li Zhen, am still one year away from taking the martial arts exam... What a joke! What does the villain in the textbook mean? Gaowu➕Cultivation➕Monster➕Martial Arts➕Sand Sculpture
