The bearded man knew very well that he could not say anything now.
He would treat what had just happened as a dream. It was enough for him to know and he didn't need to tell anyone.
If he really did that, he would be harming his companions.
Most importantly, his companions might not believe him if he told them the truth.
Now, all the cultivators believed that they had unleashed their divine might and destroyed these Reapers.
He didn't think about how strong he was, how could he annihilate all these Reapers without any damage?
The bearded man knew the truth.
It was the same master who had destroyed the patrol ship and stopped time that had altered the memories of all the cultivators except him.
Now, he had even disguised himself as a dead companion and mixed into the team. Who knew what he was going to do?
The big-bearded man thought of this and sneaked a glance at the cultivator who had 'come back to life' but was not familiar with him.
