"Let's go take a look." Ignoring Lei Xun's explanation, su Jie and Gu xueshang both understood that there was something fishy about this underground tunnel. They followed the soldier's lead and arrived at the Lei clan's Castle, in a large hall.

The hall was surrounded by soldiers. In the middle of the hall, there was a passage leading to the underground. A damp smell could be smelled. It should be an underground warehouse or something. It was dark.

"Emissary su, let's go down and take a look."

Gu xueshang's cold voice rang out.

There could be danger in this underground tunnel. The demonic cultivators in the Lei clan's Castle could be hiding in this underground tunnel. Ordinary soldiers would not be of much help and might even be a burden to them.

"Yes." Su Jie nodded.

The two of them took the torches from the soldiers beside them and went down the underground tunnel.

Gu xueshang walked in front, and the two of them went down the stairs for about a hundred feet.
