It took Zhang Tie half an hour to pass through the tunnel-like entrance of the city gate of Emperor NvWa City.
Zhang Tie just walked leisurely. However, many youngsters had started to run the moment they entered the tunnel.
Half an hour later, Zhang Tie finally felt bright in front of him as he walked out of the tunnel and entered Emperor NvWa City.
Zhang Tie saw a square covering about 1.5 square miles, which was paved with bluestones. The main road circled around the square like a roundabout. The roundabout extended to south, north and east respectively. Zhang Tie saw undulating mountains and villages in the distance.
