The protagonist's time travel has a moral system, which is moral but not moral. Famous, very famous. Nothing is called the beginning of heaven and earth; Being is called the mother of all things. Therefore, if it is always absent, I would like to observe its wonderfulness; if it is always present, I would like to observe its beauty. The two have the same origin but different names. They are both called xuan, and xuan is xuan again. They are the door to all mysteries.
