Before the war, the underground tunnels between the cities in the Barren Land were indeed still open, but right after the war started, the tunnels from The Rising Sun City to the other cities were completely sealed by Shen Yanxiao.

She did this in order to prevent accidents. If The Rising Sun City failed to stand, people in the other cities would still have time to prepare to flee.

Shen Yanxiao's approach was not hidden from others, and the Qilin Clan naturally knew it.

Grandpa Qi, as an old fox, had long calculated the difficulties that The Rising Sun City might encounter, so before the war, he secretly gathered a group of people. These people were basically unarmed teenagers that didn’t have any fighting capacity. He captured ground beetle beasts for each of them. Ground beetle beasts were only low-level magical beasts, about the size of a vole. This kind of magical beast was of no use at all in the battlefield, but it had a special role in logistic support.
