Chapter 1258: The Trump Card of Fire-Dragon Corps

It was hills and basins in the periphery of Xuantian Eighteen Mountain Peaks. The largest basin covered over 16,000 square miles. The basins were surrounded by grotesque and magnificent high mountains. The lowest mountain was over 1,000 m high. Looking down from the sky, the mountains around those basins were like petals of an open flower. However, Xuantian Eighteen Mountain Peaks looked like special stamens in the flower.

After a few months, a wide and tidy industrial park covering about 10 square miles had been built near that town of the residence of Iron-Dragon Sect at the foot of the Xuantian Eighteen Mountain Peaks.

Outside the industrial park was a universal airport, which was connected to Tongzhou Province, Yanzhou Province and Youzhou Province through railways and highways.

Zhang Tie directly took Commander Cheng and Gao Tianqi into a factory of that industrial park.
