Hearing Gu Zheng's words, Qiao Xi's heart instantly ached. She originally thought that Gu Zheng was tolerating the Lu family because he wanted to destroy the Lu family bit by bit and make them gradually collapse.
When Ji Nan mentioned the servant's identity, Qiao Xi realized that Gu Zheng had arranged for his people to stay in the Lu family many years ago. Even Ji Nan did not notice it, which meant that Gu Zheng was already prepared to take revenge.
10 years ago, Gu Zheng established Gu Corporation. From then on, the Lu family was no longer in a position to fight him. At that time, the Lu family had already begun to decline without Lu Qingyun. However, this change was small. Hence, although Gu Zheng had already started to guard against the Lu family, he had never attacked them.
