Rise of Xixia

It is said that the Song Dynasty was a good time, and he lived a happy life by copying books and picking up girls. Zhang Zhongheng accidentally came to Jiading in the Southern Song Dynasty for nine years. However, what made him depressed was that the coordinates of the crossing were a bit off. He did not go to Jinxiu Jiangnan, but to Suzhou in the Hexi Corridor - this is Xixia, and the Han people are the ruled class. I've read a lot of time-travel novels, why do I think that when others travel through time, they can marry a lady, even if it's just to be a son-in-law, but I, Zhang Zhongheng, can only marry a widow and be the successor? Pretty little lady: My husband, my family has suffered a misfortune. From now on, it will all depend on you. Zhang Zhongheng reluctantly said: Madam, my husband will do everything possible to protect you. It is now 1216 AD, eleven years before Mongolia destroys Xixia. Zhang Zhongheng: Moman, luckily I have a golden finger.
