Ling Tianyu's words were heard by Zhong Emperor and the other three. They looked at the map, and indeed the terrain was diverse, especially with the latest news that the border city had indeed been fortified, making it costly to capture.
"I read the incoming report." Zhong Emperor said, "During the fortifications, they used tree oil and repeatedly calcined the city walls. The bricks used were fired seven times before being approved for the city."
"Quite strict indeed."
The three Tianwu Gods nodded in agreement.
"Moreover, the surface of the city wall has a special layer of metal that can resist Spirit Arrow attacks," Tianwu God added. "It's hard to destroy the walls; capturing is the only option."
Lu Zhongxun, hearing this analysis, was overwhelmed. This kind of wall reinforcement was really tough.
If it were during the times when the Ancient World Sword Gate and others clashed, it wouldn't have required such efforts.
