It was big. As they approached, the end couldn’t be seen at all. From now on, the roads of the ruins could be faintly seen among the endless buildings. Unlike the regular, horizontal buildings of the Northern Base, these buildings were scattered and irregular. Tall buildings and short buildings stood together. Round buildings and rectangular buildings were scattered. The road was a zigzag and in the centre of the city stood a dark red tower. Half the overpass had collapsed and there were dense, dry vines hanging from it. The central road contained buildings of all colours but because there were too many colours, they were unified in An Zhe’s vision and gradually blurred into foggy grey.

An Zhe looked into the distance. If he hadn’t seen it with his own eyes, he would’ve never imagined that there was such an intricate city in the world. If he was a resident here then it would be easy to get lost.

Dark clouds obscured the sun. The sky was cloudy and covered with a faint mist.

“Follow me,” Xi Bei told them. “The people of our mine often come here to find supplies and there is a stronghold in the city. In fact, it is okay to live in the city but we are afraid of monsters. Grandpa doesn’t know why but the cave is the safest. My third uncle used to feel that life in the cave was too hard and went to live in the city. Then there was no news of him.”

Xi Bei walked through the buildings and they came to a densely populated area. Large grey residential buildings were crowded next to each other and there was a square in the distance. A white sphere could be seen in the centre of the square. In the quiet city, there was only the sound of the wind passing through the buildings and their footsteps.

Lu Feng was responsible for watching the surroundings. Since Xi Bei was carrying his grandfather, he bowed his head and said, “We will arrive soon after that square.”

Just then, the old man’s throat made a sound.

His vocal cords vibrated and constantly emitted a fixed syllable. There was phlegm in his throat and his voice wasn’t clear. It was barely audible. “Ru…”

“Ru, ru…”

Xi Bei wondered, “What?”

Lu Feng’s footsteps suddenly stopped.

An Zhe glanced over and found this person staring at the square ahead.

The next moment, this person spat out a short syllable. “Run!”

There was no time to think. An Zhe was yanked on the arm and subconsciously followed Lu Feng, who ran into the nearest building. Xi Bei didn’t know what was happening but he quickly followed with his grandfather.
