When Duke Yong's group heard this voice, they immediately all knitted their brows and revealed worried looks.
That was because the owner of this voice was not someone that Duke Yong or anyone in his group recognized.
This should be a place that was hidden from everyone because it led to a place that was a kilometer away from the city. There shouldn't have been anyone else that knew where this secret passage ended.
So why were there these people here now?
The guard captain waved his hand and the guards came in front of Duke Yong.
There were only a few people in the enemy group, so as long as they worked together, they would be able to break through and get Duke Yong out of here.
After all, all the guards that had come along to guard Duke Yong were the elite personal guards of Duke Yong. Not a single person here was weak.
But to their surprise, the other side suddenly released their aura and charged forward.
