Could it be that Han Xing had his own account in the Second World and was earning money there? Only in the Second World could Han Xing accumulate a huge amount of wealth in a short period of time. Han Xing would never abandon his sick sister, so he definitely had some special means to make money.
Unfortunately, these private detectives couldn't dig into the bank accounts. Liu Feng could roughly guess that since Han Xing knew the people of the Shangguan family and the Zhao family, he naturally was somewhat valuable enough to make friends with them. What's more, the money that Han Xing used might have been given to him by these two people.
He and Han Xing had been good friends for so many years. Han Xing had many women chasing after him when he was in school, not to mention his identity as a rich second-generation heir. This was also the reason why he had always been jealous of Han Xing. When Luyao tried to seduce him, he immediately agreed.
