"What's your secret?" The Second Prince started the conversation with his younger brother.
With everything under control, they didn't need to attack anymore as the firepower from the other was enough. So, the Second Prince used this chance to satisfy his curiousness about how his younger brother could do such feat.
The Fourth Prince answered with a mysterious smile, "I have my own secret. If I tell you then it would not be a secret anymore."
"So, now you have grown up and started to keep a secret from your brother? Okay, fine with me." The Second Prince pretended to get angry.
The Fourth Prince only answered with a shrugged in his shoulder before the Second Prince continued, "How much did you spend?"
"Around 500 million golds." The Fourth Prince answered didn't care.
"Later, I will transfer half of that amount to your bank account."
