One night, the Nohara family dreamed of the "ancient beauty" that appeared in the costume drama at the same time. Although the whole family thought it was incredible, they did not pursue it in depth. When Xiaoxin came back from kindergarten that afternoon, he saw Xiaobai desperately digging a hole in the courtyard, and when Xiaoxin also started digging, he unexpectedly dug out a box with letters written by Xiaoxin himself, in addition to the words with Tianzheng for 2 years. Also painted with fat left door pattern. Xiao Xin closed his eyes and thought because he couldn't figure it out, but when he opened his eyes, he found that he was already in the warring States period and saved the samurai. As a result, he was able to meet the beautiful woman in his dream, Princess Lian.
