Time is so long, like a long river, drying up, like the setting sun, round and round. Promise. The promise made in Chang'an is not a rumor or a message. It is a lifelong journey in Chang'an. The sunset continues.
Gu Xiangli made a promise to King Qinchuan that he would bring Princess Qin Luo back to Chang'an safely, but he did not bring back her heart. After the fall of Chang'an, Gu Xiangli made a promise to Qin Luo that he would help her regain Chang'an, but he lost himself. Finally, Qin Luo stood on the city gate of Chang'an in military uniform and silently made a promise, as long as you don't die, I will give up anything.
