Following that, Huo Yuhao saw the Sun Moon Empire Army begin setting up some machinery around these metal pillars.
This was the first time Huo Yuhao had seen such machinery, and he had no idea what they were. They appeared to have a complex structure with faint soul power fluctuations emanating from them.
These machines were highly precise. Although Huo Yuhao could imprint their forms in his mind using Spiritual Power, he had to get closer to them. But he was currently five kilometers away from the Sun Moon Empire Army. Getting too close would make it easy to be discovered, so he was in no hurry.
Huo Yuhao thought, "No, I must go and have a look tonight."
He believed that with his understanding of Soul Guidance Devices, as long as he could observe the core magic arrays of these devices, he should be able to figure out their purpose.
