Although the landmass of Sector 9 wasn't big, Lin Sanjiu was amazed that it could hold so many posthumans.
There were four stone cyan staircases that acted as bridges between the inner city and outer city. Sirens went off madly in quick succession across the entire city. One after another, human figures hopped down the staircases frenziedly, gathering around the main gate.
By the time Lin Sanjiu and the goateed man's group arrived at the main gate, there was more than hundreds of posthumans gathered there. The number may not sound that significant, but upon turning the figure into numbers of humans, it was enough to cause a huge congestion at the main gate.
