Zuan is not only incredibly powerful, but also possesses unparalleled cultivation. Most importantly, he's handsome and knows how to charm women, so it's not surprising that my sister fell for him.

She knew that Zuan was a womanizer, but she didn't take it to heart because, in her opinion, it had nothing to do with her.

But when she found out that her sister was also having an affair with him, she really couldn't hold back anymore.

I was here first...

The thought flashed through her mind, but she quickly dismissed it. She looked at Zu An with a frosty expression and said, "You used to call me 'sister,' but now I'm the one calling you 'brother-in-law.'"

Zu An chuckled awkwardly, "From now on, I'll still call you 'sister,' and we'll address each other as we're family."

Shang Liuyu raised an eyebrow: "You really want to be my brother-in-law?"

As if to vent her anger, she grabbed Zuan and gave him a good beating.

Zu'an didn't defend himself, letting her hit him as she did so, occasionally letting out a shrill scream.

After a while, Shang Liuyu withdrew his hand, his face slightly red: "Alright, alright, with your cultivation level, it's no different for me to hit you than to tickle you. You're acting so pitiful, it's not like you're putting any effort into it."

Thinking of his exaggerated acting just now, it was as if she saw that lazy boy from back then again, and she couldn't help but chuckle.

"It really hurts. I'm so sorry to have upset Sister Shang. It hurts my heart." Zu An sighed.

"Pah!" Shang Liuyu spat, his face hardening. "With foreign enemies at hand, I'll let this matter slide for now and settle accounts with you later. When we get back, don't tell my sister that I already know your identity."

"Huh?" Zuan was stunned, not knowing what she was up to.

“My sister has always been dignified and reserved, and our mermaid clan has a tradition of fidelity that has lasted for thousands of years. If she finds out that I know about these things, she will be embarrassed,” Shang Liuyu said worriedly.

Zuan was taken aback. He hadn't expected her to be so considerate. She was truly a rare find.

However, Shang Hongyu is dignified and reserved?

Passionate as fire!

Unexpectedly, this younger sister, like those outsiders, didn't understand her true feelings.

"But if she finds out we kept her in the dark, she'll definitely be furious." Zuan thought to himself that he had just dealt with one, and now another one was about to explode at any time. Just thinking about it made his scalp tingle.

Shang Liuyu glared at him: "Weren't you two keeping me in the dark before?"

Sensing her resentment, Zu An immediately fell silent.

"Also," Shang Liuyu's face suddenly flushed, and she glared at him, "you're not allowed to tease my sister on the wall next to mine anymore!"
