Margrave's Bastard Son was The Emperor - Chapter 258

After being adopted by the Su family for so many years, Su Yan had always been grateful to them for raising her.

Within the walls of her family, she was filial, kind, and did everything she could to please her family. Outside those walls, she and her fiancé, Huo Nan, were on par with each other. They were an immortal couple that was respected by all. She loved Huo Nan to the core and even gave up her kidney for him.

This continued until the real daughter of the Su family, Su Qian, returned. Huo Nan betrayed Su Yan and climbed into Su Qian’s bed. He even allowed Su Qian to wantonly frame her and disfigure her!.

Su Qian even slandered Su Yan for seducing her fiancé. The Su family believed her and insulted Su Yan with the most unpleasant words in the world. However, they forgot that before Su Qian returned, Huo Nan was Su Yan’s rightful fiancé!

After she was killed, Su Yan was reborn to her 18th birthday and started her crazy path of revenge. Step one, inherit assets worth billions; step two, kick the scumbag to his death; step three, personally slice her white lotus of a younger sister.

In this life, all she wanted was to live an ordinary life with her blind and lame husband. After all, this man continued to help her willingly in her past life even though she rejected him countless times while her dearest husband betrayed her so ruthlessly!

One of the few self-cultivator who exist in this modern world; due to an unfortunate event, completely destroyed his body in an explosion. Using all his effort to save his primordial spirit, he ended up in an strange magical world and had to start all over again. From a fallen aristocrat to the Warlord of Chaos, this can no longer be summarise as legendary; this is the life of the God of War.
