There should be something wrong underground.
Li Yuanqing quickly shifted his gaze to the ground. He was different from others. Others would probably have to spend some effort to burrow underground, but for him, it was not difficult to go underground.
His flying ants and man-eating vines could dig holes, and they were especially good at developing underground.
However, they could not see the source of the death energy and could only blindly dig holes. Therefore, Li Yuanqing quickly gave the Man-eating Vine and the flying ants a mission to dig holes thousands of meters underground.
Why did they have to dig so deep? That was because this was outside the city and there were thousands of cultivators living here. Even if some of them were suppressed by the demons, there might be experts hiding deep.
Li Yuanqing was already very cautious. Now that he was in an unfamiliar place, he was even more cautious. He would rather take things slower than take risks.
