What is the final outcome of the Shahai Li nationality?

Here's the question. Sand Sea is an excellent modern TV series, which is adapted from the novel of the same name "Grave Notes Youth Sand Sea" by Nanpai Sanshu. Li Cluster, an ordinary high school student, is involved in a huge plan aimed at the current situation of the world, and meets Wu Xie, the mastermind behind all this, who is a travel photographer Guan Gen. It can be said that the final ending of the Li nationality in the play is not quite what everyone expected at the front end, but this does not mean that the ending is not good, but it only increases the sense of reversal of the whole plot and makes people feel more ups and downs. In the twenty-third year of Wang Jiali, Li Cuo disappeared from the wheelchair by the lake and never appeared again.

This has never happened in the history of the Wangs. An outsider disappeared like steam in the core area of the Wang family, under the supervision of someone in a huge closed system with heavy security.
