Reason:
The Zhang family has kept secrets for generations, and the world is the best. Only the patriarch of the Zhang family can know what the secret is. They kept moving their ancestral graves, looking for a treasure trove of feng shui, and continued to guard their secrets. The family strictly implements the policy of intermarriage to ensure pure blood. However, in the course of history, they are still influenced by the development of modernization.
The strength of the Zhang family was weakened and the phenomenon of ethnic separation began to appear. They can no longer protect the ultimate goal. They found the head of the Old Nine Gates, Zhang Daren, and formed the Old Nine Gates to continue guarding the Zhang family. However, things are not that simple.
From the second generation of the Laojiu family, they began to rebel against this mysterious family, and the descendants of the old nine families were also involved. Chyi Yu is the second generation descendant of the Laojiu family.
Wu Xie is the only descendant of the third generation of Laojiumen Wu family. Being raised as Chyi Yu confused the realization of the Zhang family and confused them with Chyi Yu and Wu Xie, so that Wu Sansheng and Jie Lianhuan successfully completed their resistance to Zhang Jiahe's "it".
Extended information Chyi Yu and Wu Xie:
From 65438 to 0976, Chyi Yu, together with the second generation of Laojiumen, formed an archaeological team to attend the funeral of Zhangjia Gu Lou in Bajiao, Guangxi. Ma Pan acted as a guide in the middle, and killed the archaeologists on the ground in order to seize the white rice. Jie kuya's men took the opportunity to replace the fake archaeological team, burned the coffin, sealed the body with molten iron, and then fled with the body.
At that time, several players at the scene, including Chen Wenjin and Huo Ling, dodged a bullet. I still don't know whether concubine Yu was killed and replaced by kuya at that time, or whether she is still alive with Chen Wenjin.
1984, Chyi Yu (I don't know if he was replaced by kuya) participated in the Xisha archaeological mission assigned by the Archaeological Institute. According to the scene seen by Wu Xie in A Dream of Qinling Mountains, Chyi Yu was strangled by Wu Sansheng/Jie Lianhuan in the submarine tomb and passed out. Whether it really happened remains to be discussed. After that, the archaeological team was stunned by Wu Sansheng and Lian Huan in the submarine tomb and handed over, and was sent to Golmud sanatorium for imprisonment.
1990, Chyi Yu looked through the materials of "Archaeology of Shangsi Zhangjiapu Site in Guangxi, 1956" in the archives room on the second floor of a university in Changsha, and took some papers from it, then left a thin golden seal on the door "16, 990, sealed by the Institute of Archaeology of XX University".
In 2004, a man who looks exactly like Wu Xie appeared in Guangxi, acted as a guide for Qiu Dekao, then pretended to be Wu Xie and took the letters sent to him. It is impossible to determine whether it is Chyi Yu, Zhang Haike or others.
