If it had been a complete map of the Empire, Yu Lian might even have considered it more valuable than the spoils seized from the underground warehouses.
"The Kaitai Kingdom has no troops left to defend itself, and no natural barriers to fall back on. Judging from the routes on its military star chart, it would take us only two or three weeks to carry the fighting all the way to its capital," Yu Lian said.
