General understanding of the spoilers:
While Shin was waiting for reinforcements to attack Yan Shi, he realizes that the castle was taken. Upon investigation, he discovered that it was taken by Yontawa. The author also quoted a relevant line from Shiji, in which records Yontawa’s capture of the Yan Shi castle during the 9th year of Qin Shi Huang’s reign.
-Shin says that Yontawa seems to be a strong competitor for the 6 great general position, and says that he will not lose to her.
-Yontawa’s capturing of Yan Shi castle was a great blow to the 6 states.
-Chapter ends with the news of Shushinkun of Chu being assassinated(which was also part of history).

According to the translation from a tieba user, the current confirmed members of the 6 GG are Moubu and Tou. Ousen and Kanki are most probably going to join them soon and therefore there are only 2 more vacancies left. These nformation were provided by Mouten and Ouhon as Shin, Ouhon and Mouten are currently attacking CaoZhou of Zhao.
With Yontawa appearing to aid Qin later against Castle Yan Shi of Wei, she could also become one of the 6 GG. T
