Weapon seller in the world of magic

As Song Yun stood as a guard at the entrance of the waiting room to make sure no one disturbs his daughter and son-in-law, both of them took their seats and started drinking water.

Mark then collapsed on the sofa and fell into deep thoughts.

"Okay, so far, I earned about 1,773,500 gold coins only from the rights. And all of that belongs to me. The system would gain nothing because it doesn't have any authority over the rights.

Since I only became richer from this event, I don't need to feel stressed about the biddings that didn't meet my expectations.

Hmm… wait a second. If I add the weapon sales, then, it will be over 2 million gold coins, correct?

If I had to give away 2% of my income to Song Yue, then, I should already give more than 40,000 gold coins to her. And what about the remaining items? If it will cross 10 million, I might have to give more than 200,000 gold coins to her.
