Xuanhu North and South

In the future, a young man accidentally invented a machine that can travel through time while thinking about the special and general theory and the difference between black holes and white holes. In fact, he did not know that he had invented such an awesome machine. For him, he knew that when he used this skill, he had already reached a dynasty unknown to him. (Because the history of predecessors has been further simplified in his period) Therefore, he searched for the energy to restore the machine in that unknown dynasty. (A very special kind of crystal: Caibai crystal) He traveled back in time and found that he couldn't understand what his predecessors said. He wanted to try to blend in without being discovered or killed. He knows very well that people who are not of my race will have different minds! While trying to adapt to time and space in panic, he discovered that he did not have a pass to this place. To people here, he is a fugitive or a refugee. He had many industries he wanted to try at the beginning, but found that in this time and space, these were only available after official after-sales service. But he also has extremely strong medical skills. Due to the development of technology in the future, most surgeries will be conducted through 3D simulation experiments. Therefore, it is not difficult for him to treat patients in this time and space. In the process, he kept thinking about his current life. I have never given up my vision of returning home and do not want to be assimilated by this era. Finally, he found Caibai Jing, but during this period, something happened in his original time and space that he could not accept. So he created a second self in the modern time and space where he disappeared, forming two parallel lines. A new journey has begun!
