They waited for Feng Yun to exhaust his strength then kill him.
Today, the one who came to ambush Feng Yun was one of the members of Long Yi's group.
That person was called the black shadow. He must be very good at assassinating people.
If it wasn't for Feng Yun's sharp senses, he would have become a cold corpse now. The average person won't be able to react in time while facing this perfect type of sneak attack. At that moment, thinking about it, even Feng Yun felt a little lucky.
He'd never imagined that this group of people would actually be able to conceal their auras.
Just now, he was completely distracted when dealing with Remnant Souls with all his strength. Afterward, when he saw the Dantian Pill, his vigilance was lowered to the lowest. Otherwise, with his mental strength, he should have been able to discover these people long ago.
