Unedited chapter**
Xion didn't say a word in response, he knew Colton more than anyone and understood what he was trying to do. There's no way anyone he would have found out about Wang Shi. No one could. Colton was just trying to get information from Xion based on his probability.
Or maybe he really found something. Xion waited for Colton to reveal more information.
Suddenly Colon started laughing, it was a known Xion would never fall into his trap and say anything. "I know you won't confess. Then let me show you something...." he took out two folded papers from his pocket and place it on Xion's table.
When Colton's men came back with zero information about the person who bought the heart, it raised Colton's suspicion. There's no way the king of the underworld wouldn't get information as small as this. It never happened before!
