Just outside Liangzhou City, there is a segment of the Great Wall, acting as a barrier between Liangzhou and Tubo. Actually, long ago, the land now occupied by Tubo once belonged to the Central Plains, while this side was the territory of the Turks, so the Great Wall was originally built to prevent people from moving south.

Manbao was puzzled and asked, "Tubo could simply move west, why would they even consider heading north?"
After a moment of thought, everyone agreed it was a good point. Bai Erlang commented, "So the Great Wall is actually blocking us now."
He said, "And Tubo benefits from it."

Bai Shan shifted the topic, "Are there no soldiers guarding the Great Wall?"
