Mike seemed ready to end the conversation, but Yang Yi was eager to resolve some doubts through Mike, so he urgently said, "Mike, Brian's interrogation has led to Deyo Mather gearing up for war against Big Ivan. I know Deyo Mather is an arms dealer, but who is Big Ivan?"
Mike nodded and said, "Big Ivan is certainly an arms dealer, and in fact, he's the biggest arms dealer in the world. He's Russian and rose to power quickly by trafficking arms after the dissolution of the Soviet Union. This guy's methods are extremely vicious. He controls at least forty percent of the market share; he's a super heavyweight in the arms black market."
"As for Deyo Marcel, he holds about twenty percent of the market share. Although he's also a major player, he's quite far behind Big Ivan. However, both men wield too much influence in the underworld. Their conflict is akin to war between the United States and Russia, surely triggering turmoil in the underworld and leading to a world war."
