Barlin's Reiki sense was a class above Charlie's.

On one hand, while his cultivation was definitely higher, it was also awkward that he didn't have much chance to replenish his Reiki—unlike Charlie, who had ample amounts of pills to recover.

Hence, like a starving beggar, he was sharper when it came to the smell of food, his body hair standing and tingling when Charlie's Reiki reached him.

He didn't hide his Reiki presence since he was in a cave this deep, and the surface was no man's land.
