I, a prison guard in the Heavenly Prison, secretly became invincible thanks to the system.

Chapter 814 Demon-Slaying Valley, Thunder Demon Sect

Lan Ningshuang's true spirit is a blue fish.

All true spirits possess great power and unique characteristics, but she did not reveal them at this moment.

A moment later, Lan Ningshuang withdrew her aura, closed her eyes, and landed.

She exuded an aura of tranquility, a stark contrast to her previous sharp and assertive demeanor, like a sacred tree that had withstood the test of time, steady and serene.

Ye Kang knew that she had successfully undergone a rebirth.

Lan Shuangning is now a true first-stage Nirvana powerhouse.

Of course, only the first Nirvana involves such a terrible process of breaking down and rebuilding.

Each subsequent transformation only increases power and cultivation; it will not shatter again.

Lan Shuangning opened her eyes, took a long breath, and smiled at the two of them.

"I'm grateful to my two junior brothers for protecting me. I'm glad I did not fail in my mission."

Congratulations, Senior Sister, on your breakthrough to Nirvana!

The two men simultaneously cupped their hands in congratulations and bowed deeply.

According to the rules of martial arts, after Nirvana, there is a fundamental difference between oneself and Xingluo, and etiquette must not be forgotten.

Lan Shuangning accepted the greeting and then said, "This time, I owe a great debt to Junior Brother Ye. If you hadn't helped me resolve the toad poison calamity, I certainly wouldn't have been able to break through so smoothly. You gave me such a generous gift on our first meeting. As your senior sister, I cannot rest easy if I don't repay you."

Ye Kang said in a panic, "Senior sister, you are too kind. This is my duty. Besides, I still have a lot of the array materials that you gave me before. I am the one who benefits."

“One thing at a time. Those materials are just a bonus for you. We should repay you. Just tell us what you need.”

Ye Kang did not refuse again. Lan Shuangning was a straightforward person, something Lu Zhian had already reminded him of.

If you keep being polite to her, it will only make her unhappy.

Ye Kang said helplessly, "To be honest, Senior Sister, I have been ordered by the Headmaster to achieve Nirvana within three months. This is quite difficult. Could you give me some advice?"

"What! March?"

Lan Shuangning and Huixin were both stunned, thinking they had misheard.

Three months of rebirth, has this school leader gone mad?

However, seeing Ye Kang's current cultivation level, Lan Shuangning understood something.

"You've already reached the Four Stars stage, breaking through once in just a few days, and your aura is stable, showing no signs of being forced to grow too fast. You truly are a genius; no wonder your academic leader said that. However, three months is still a bit too rushed. Why is she in such a hurry?"

Ye Kang shook his head: "This matter is of great importance, please forgive me for not saying more."

"No problem. Since that's the case, you must not slack off. Nirvana requires opportunity, but I still have some ways to break through minor realms."

"Please tell me, senior sister."

Lan Shuangning thought for a moment and said, "I have been to the Demon-Slaying Valley before. There are ruins of the Thunder Demon Sect there, and countless opportunities await you. Perhaps I can help you."

"Thunder Demon Sect?"

"That's right. Back then, the Wanlei Sect in Leizhou was at its zenith, but the sect split up. One faction fell into the demonic path and established the Leimo Sect. The two factions had irreconcilable ideologies, which triggered a great war that led to the downfall of Leizhou. The Taizu also took advantage of that chaos to rise to power. The Dangmo Valley was a battlefield and also a branch of the Leimo Sect."

Ye Kang and Hui Xin listened, completely stunned.

They were all well-read, but few books mentioned the name Thunder Demon Sect.

Lan Shuangning actually knew such a secret; she is indeed very experienced.

Ye Kang said, "Since there is such an opportunity, I imagine many people will go to explore it, right?"

"Naturally, only the top talents from each prefecture of the Martial Dynasty know the location of the Demon-Slaying Valley. Therefore, everyone who goes there is a super genius, stronger than you, not weaker. I only went there once by accident, but my strength was insufficient, so I dared not go deep and could only flee in panic. By the way, I also obtained my Blood Soul Silk Divine Power from there."

Lan Shuangning stretched out her right hand, and a blood-red thread emerged, constantly moving around her fair, jade-like arm.

Ye Kang was startled.

I never imagined that such a powerful supernatural ability would be found in the ruins.

This also shows that there is indeed a great opportunity in the Demon-Slaying Valley.

Just then, the system voice suddenly rang out.
