Although the Eighth Sanctuary had been established before, it was usually during wartime.
In other words, it is not a regular official position.
Moreover, those who have concurrently held the position of the Two States Guardian must also be head-level figures of the Sanctuary. Apart from Qiu Tu and Elder Pang Pang Haichen, the last person to hold this position was Elder Tang.
Therefore, once this position is given to Qiu Tu, it actually signifies the formal recognition of Qiu Tu's status in the entire Sanctuary — equivalent to a faction leader.
The issue is, the big pancake doesn't end here.
If the big pancake ends here, then at most, it is just the word "two" written by Elder Tang.
Qiu Tu keenly detected the scheming of Old Rao and Elder Tang, so he wrote "four" because... the position of the Two States Guardian was not a chip offered by Old Rao and Elder Tang.
Let Qiu Tu "command the four states"! That's the true purpose of the two elders!
