[Qin] Am I the First Emperor's Teacher? !

The Song and Tang Dynasties traveled through time and picked up a child to teach as a student. Later, the child was taken back to Qin. Suddenly one day, oh, the child wrote a letter saying that he had become the King of Qin and sent someone to pick him up and take care of him in his old age. Old Man Tang of the Song Dynasty: emmmmm, let him take it easy first. The child's experience is somewhat familiar. Let him first think about what he has taught the Emperor of the Ages. Ying Xiaozheng: Teacher, I want to go to heaven! Song and Tang: No conditions. Ying Xiaozheng: Teacher~ Song Tang was soft-hearted: Okay, I'll give it a try. Gliders and hot air balloons are all available! Just try and try, and accidentally create the prosperous Qin Dynasty. Ying Zheng was a hostage when he was young, and was looked down upon and ridiculed by others. It was not until one day that an immortal descended from the sky and became his teacher, that he knew what the world was and what a mind was. The teacher had many disciples, and Ying Zheng was proud that he was the teacher's favorite student until Fusu was born. Song and Tang made a large number of children's toys and literacy cards, and also built a small playground in the yard, where they studied and played with little Fusu every day. Ying Zheng: Teacher, you didn't even accompany me like this at that time... Song and Tang: Oh. When the First Emperor was a child, he had a sullen face all day pretending to be an adult, how could he be as cute as the soft Fusu! Mission: Believe in the power of science
