Mine vein, tongzu mountain

In this case, Lu Ming could not take action because it was not worth it. If he was exposed and he was besieged by the experts of the heavenly human tribe, he would be in trouble.

Lu Ming observed for a while and left the place, heading to another mine.

He found that the other mine was similar. They also collected once a day and left without any delay.

Lu Ming went to a few mines in a row and they were all the same.

Lu Ming could even sense several powerful auras hidden in the dark around a larger mine.

One of the auras made Lu Ming feel a sense of danger.

If not for Lu Ming's sharp spiritual senses, he would not have noticed it.

It was obvious that the heavenly human tribe was hiding in the dark. If Lu Ming appeared, they would attack him.

However, it could be seen that the heavenly human tribe did not have enough people. Otherwise, they would not have only set up ambushes in the larger mines and left the smaller mines untouched.
