Boy group EXO's member Chanyeol talked about the 'pathcode' that EXO used for their album promotion.

On Monday, EXO held a showcase for their second album, "Exodus," in Seoul.

About the 'pathcode' promotion teasers that were used for "Exodus," Chanyeol said, "They explained it to us but I don't really get it. I couldn't solve all of them. I trust that if our fans love us, they'll be able to solve it easily."

"For example, I solved D.O.'s," said Chanyeol, and D.O said "I couldn't solve Chanyeol's no matter how hard I tried," bringing laughter to the reporters.

EXO released "Exodus" on this day and officially began their comeback.
