In 2121, when technology is developing rapidly, time travel technology has been successfully developed.
Everyone is watching China's growing power. They want to know why a country with an underdeveloped military and not top-notch technology can become a development power.
In order to prevent other countries from becoming jealous and using technological means to travel through the past and disintegrate China, we deliberately released the news: the secrets of the country are sealed in the body of a twelve-year-old boy. As long as you go back in time and find him and take him back to the present timeline, you can get his guidance and get the most important core of China's success.
Intention: What I have to do is to carry on carrying thousands of nameless beliefs and keep going, and protect my timeline.
