His Life Ability is why this three-eyed man is behaving as if he designed the tunnel system and knows its every secret. It is why he is catching up to someone even though that person had a head start on him.
Eventually, the person he was pursuing reached a dead end and couldn't go any further. So he was able to finally meet them.
Even before he reached the dead end, he could see the light of a torch coming from around the corner. So he didn't need to have special eyes to know that there was someone around the corner with a torch.
In order not to spook the other person, he said, "I come in peace. I hope we can talk."
His words should have sounded strange to the other person because he was speaking in a strange language. But by using his mental world to communicate with the mind of the other person, they could understand what he was saying.
