It Is Better to Be a National Teacher Than to Fight in the Palace [Qing Chuan]

Dressed as Emperor Yongzheng's mother-in-law, she became the national preceptor. High-yield potatoes, cement, glass... She can do it all! Emperor: Your Majesty, why are you still so young? Imperial Master: Immortality, do you believe it? Emperor: Where is Penglai Island? Imperial Master: Stop asking, you can't go, don't even think about taking the elixir. Emperor: The Queen has stolen my character. Third person, feed logic to the dog, just feel comfortable. Brainstorming, no fighting Mission: Science and technology change the world, develop the world, and work for world peace.
