The location of the Tianlin Mansion was adjacent to the forest on the outskirts of Jingmen City, so it would be easy for Xu Yuan to search for an underground base to be used as the main headquarters of the Demon Army in the future.
The dungeon area that reaches 50 hectares will at least be able to accommodate hundreds of thousands of soldiers.
Xu Yuan slightly remodelled several corners of the room. He bought several training facilities from his system shop, such as a large Dojo in the centre of the room, which tested each soldier's strength by holding battles.
He also placed ponds of Yang water and Yin water in the west and east. Against each other, the use of the two pools was none other than to strengthen his troops by immersing in them, which would be of great benefit to all his soldiers.
The water of the Yang pool will benefit the men, while the Yun pool will benefit the women.
