MTL - Taoist Master and the Cat - Chapter 71

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!

Rumor had it that Qiao Xi had a weak constitution—a sickly beauty. Rumor had it that she spent a fortune every day on medications—eating them like candy. Rumor had it that ten servants waited on her by her bed every day—a burden to everyone. They were all waiting for the Qiao family to toss Qiao Xi back to the countryside and leave her to fend for herself.Qiao Xi: "They're all saying that I'm weak and can't take care of myself. Apparently, I spend money recklessly as well.”She looked down at her tattered shirt and was exasperated.Qiao Xi: “Are you saying that this wealthy family lets their daughter wear tattered clothes every day?”The Qiao family's rich daughter? She had enough! She would not be it anymore! Therefore…Scumbag guy: "Without the Qiao family, you're nothing."Qiao Xi: "If I'm kicked out of the Qiao family, I'll be done for."Scumbag girl: "Sis, don't be too disappointed. As long as you work hard, you'll be praised one day.”Qiao Xi: "Shut up, I don't know a traitor like you."The scumbag guy and girl: "???"Rumor had it that the Gu family's youngest son, Gu Zheng, rashly married a woman who had nothing but looks.Qiao Xi: "Is someone looking down on me?"One day, Qiao Xi saw one of Gu Zheng's employees racking his brains over a series of numbers on the computer screen. Since she was free, she lent a hand.Did she just crack the firewall created by the joint efforts of top elite hackers?!Gu Zheng inched closer with every step. "Qiao Xi, what else are you hiding from me? Hmm?"Qiao Xi: "Oh, no! I feel dizzy again! I'm so weak. This body of mine is just too weak!"

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.
