However, the army was surprised that Mr. Zhang had returned to the ancient times, so it was anxious to return to the Ming Dynasty for rescue. Xiaodong also admitted that he was the bane of Wei Zhongxian, so he didn't want to go back to the Ming Dynasty. So the army and a wave of disputes led to the army finally breaking with a wave of small things.
When everyone thought there would be a happy barbecue ending, it turned out that after Zhang Cheng returned to Daming, he announced that Dajun, Yibo, Xiaodong and Crown Princess had died. But the four of them suddenly had angina pectoris and were trapped in a modern elevator. When they woke up, they found themselves completely unrecognizable, and all their acquaintances didn't know them. Later, they looked up the history books and found that their deaths in the Ming Dynasty changed history, which in turn affected the development of modern times.
I think the ending is very good. Do happy endings have to be together? Regret is more memorable, isn't it? Although the four of them went back, the real world returned to the right track and the butterfly effect disappeared. But the memories left in the hearts of the four of them are eternal and unforgettable.
