The purpose of Ling Zhenfei's visit to the hospital was to provoke Le Jianxing into anger.
Only if Le Jianxing, the old fox, became furious would he act, and only then would Ling Zhenfei have a hope of catching his fox's tail.
In fact, he had long noticed that Le Wu Ya was nothing but a good-for-nothing pretender; it was impossible for the Chen family to choose him as a partner.
Le Wu Ya was likely just a representative for someone or some force, with someone manipulating him from behind the scenes.
After much reflection, Ling Zhenfei concluded that the person controlling from behind must be Le Jianxing.
Le Jianxing was wealthy but unkind, meddling in any business that made a profit, regardless of morality. In Binyang's political and business circles, he was notorious. He could completely use his wealth to instruct his son to engage in illegal activities for money.
