All of Lu Xiao's subsequent plans were affected, and the one who influenced him was Si Yuchen.
Unexpectedly, Si Yuchen would have such a huge impact on his plans. If Lu Xiao had known earlier that Si Yuchen would significantly affect his plans, he would have found a way to deal with him before coming to Sea City.
Even though he is now married to his own daughter, Lu Xiao must first achieve his own goals.
Si Yuchen obstructed Lu Xiao, making it impossible for his plans to proceed smoothly. Lu Xiao only wanted to take Gu Xiaonuan away, nothing more.
Gu Xiaonuan was Lu Xiao's only hope; without Lu Xiao, Gu Xiaonuan would still be Gu Xiaonuan, and life wouldn't be different than usual.
However, Lu Xiao was different; he desperately needed Gu Xiaonuan's help. Without Gu Xiaonuan, everything would go up in flames.
