In the southeast of the human territory was a northern border city close to the Ruins of End. There were many tall mountains around the northern border city, and the jungles were filled with poisonous gas, fierce insects, fierce beasts, and wild birds.
The surrounding areas were dangerous, and the level of danger was famous among the 300 human cities.
Beijiang city was located between two tall mountains and was the only path for humans to reach the ultimate.
The city closest to the ultimate was the most important on the human border, and this one was well-developed in commerce and had high walls. It had three gates in total.
After the first gate was a city named Wengcheng, and across the second gate were three additional city gates in front of them. Only one of the gates was correct. The remaining gate was connected to a reservoir and a heavy weapons array.
