William Liu, named William Liu by Han Fei, the grandson of Guigu, Wei Zhong and their children, has intangible power and takes "the law of heaven and earth is urgent" as its purpose. The purpose of the establishment of quicksand organization is to "know the traitor with skill and stop the punishment with punishment", eradicate the political group headed by the night that destroys the political ecology of South Korea, and finally achieve the goal of making South Korea rich and strong.

According to the current development of the plot, quicksand can gradually compete with the largest night underground organization in Korea. Although Han Fei's force value is not high, he can only defend passively, but the force values of Zhuang Shu, Sean and Zi Nv are not low. Moreover, the purpose of quicksand organization at the beginning of its establishment was not to win by force value, but by strategy and IQ. This is also the advantage of quicksand. Han Fei, Wei Zhao, Sean and Zi Nv can crush the night.

My personal guess is that quicksand will gradually expand and eventually threaten the status of Night, so Night is forced to join hands with Qin Hejing. Although the quicksand organization finally wiped out the night organization and Ji died at the hands of Wei Zhao, after infighting, South Korea was weakened and far from being an opponent of the powerful Qin State. So Han Fei was forced to go to the state of Qin and finally died in the state of Qin. After Han Fei's death, South Korea was destroyed by the State of Qin, and the children's whereabouts were unknown. Sean was forced to leave for Confucianism, leaving Wei Zhao alone to support him. In the end, quicksand failed to achieve its original purpose. These plots are basically mentioned by Qin Yuezhong. After all, "Nine Songs" is a prequel to Qin Yue, and the main plot is always in the same strain, so it is impossible to change too much.

Of course, how the plot will develop and how it will go, we will wait and see, and follow the drama every week.
