As for the method of annexation, it is quite simple.
Heavenly State and Earth State need not be mentioned. Qiu Tu was originally the garrison commander of the Two States, holding the high ground and could arbitrarily make personnel arrangements and adjustments.
Apart from positions above the Speaker level, legally speaking, he cannot decide by himself.
Almost all other positions including the senior officials of each city, State Council members, and Deputy Speakers can be decided by him alone.
While in Dongye State and New State, he doesn't have as much legal power.
But the eight Deputy Speakers of New State and Dongye State are: Tang Feifei, Rain Butterfly, Liu Xiongyuan, Dai Yukang, Yan Chen, Guo Huai, Ye Mingfeng, and Li Tingdong.
Among the 8 people, Qiu Tu has 4 staunch supporters. Yan Chen and Guo Huai now also lean towards Qiu Tu.
So among the 8 people, Qiu Tu has 6 votes.
