Lin Mu did not act immediately as he wanted to listen to more information from them. He had already waited for half an hour for what he had already gotten and decided to wait for a bit more.
His attention was also on Elder Liqiang and his condition. While he certainly was heavily injured, he was not going to die anytime soon. He was, after all, a Dao Shell realm cultivator and would not die that easily.
The Northern tribe people had evidently taken away the spatial storage treasure of Elder Liqiang, otherwise, he would have been able to heal himself with the pills he had. He would have even been able to use his other spirit tools to breakthrough the barrier that restrained it.
After all, Elder Liqiang was a formation master himself. While he might have been able to dismantle a normal barrier formation without the use of any supportive spirit tools, the barrier that blocked him right now was nothing like that.
