Early the next morning, Sargon bade his wife and daughter farewell and set out with two slaves and a few ant-people. Each of them, including the ant-people, were wrapped up tightly in gray cloaks.
Lu Zhiyu returned to the castle, entered into the main hall, and pressed a switch by the fireplace, which opened a secret passageway within a side wall. After lighting a torch, Lu Zhiyu followed the steps downward. After descending quite some distance, he came into a large underground cavern, which seemed to be some sort of a relay point.
There were four tunnels that were visible from this location, each leading off into the distance. Lu Zhiyu had used the Source Form to create this sturdy tunnel here after initially choosing the Black Forest as the location for the wizard tower.
Lu Zhiyu chose a tunnel leading to the south. It was laid with track, like an ancient mining tunnel. Along the tracks, parked by its side, was a modified train-like mine cart.
