The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

Leng Rushuang closed her eyes, feeling the surging power within her body, as if her body had been rebuilt.

The difference between the mid-stage and peak of the Tribulation Transcending Realm is just a thin veil; without the suppression of the formation, one could break through directly now.

She held back, knowing that breaking through to the peak of the Tribulation Transcending stage would definitely attract strange phenomena from heaven and earth, and she didn't want to cause unnecessary trouble for the Cangwu Mountain Tianyan Sect.

"You..." Leng Rushuang opened her eyes and looked at Shen Yifei, "Your dual cultivation technique can really help people improve their cultivation level."

"Of course." Shen Yifei lay exhausted on the bed and said weakly, "Don't you know who I am? I am Shen Yifei, the sect master of Tianyan Sect, the number one alchemist and the number one dual cultivation master in the cultivation world."

Looking at his nonchalant attitude, Leng Rushuang's lips actually curled up slightly.

She herself didn't realize that this expression was the first time she had smiled in hundreds of years.

"Thank you," Leng Rushuang said softly.

Shen Yifei was taken aback, looked up at her, thinking he had misheard, "What did you say?"

"I said, thank you," Leng Rushuang said again, "Thank you for the detoxification and for helping me break through the barrier. I will remember it."

Shen Yifei chuckled twice, propped himself up to sit up, and said, "Miss Leng, if you really want to thank me, then let's talk business."

"What is it?"

"What about the future alliance between the Heavenly Evolution Sect and the Profound Ice Palace?"

Leng Rushuang frowned slightly. "An alliance?"

"That's right." Shen Yifei organized his thoughts and began to speak seriously, "The Golden Crow Sect now controls the Demon Extermination Alliance, and that old bastard Lu Ya is taking the opportunity to consolidate all the sects in the world. Ye Qianqiu of the Ten Thousand Swords Manor has also become my mortal enemy. You are the Palace Master of the Profound Ice Palace, and as long as you are alive, Lu Ya cannot touch the Profound Ice Palace. But the problem is, he can touch my Heavenly Evolution Sect."

"So you want the Xuanbing Palace and the Tianyan Sect to form an alliance?"

"It's not just about forming an alliance." Shen Yifei looked into her eyes and said, emphasizing each word, "I want the Xuanbing Palace to be merged into the Tianyan Sect."

Upon hearing this, Leng Rushuang's expression changed instantly.

"Say it again?" Her voice turned cold again, and the temperature in the room plummeted.

"Don't think you can take advantage of me just because you saved me! Do you even know how many years the Xuanbing Palace has existed? And now you actually want to swallow it up?"

Shen Yifei had anticipated this and calmly explained, "Miss Leng, please don't be angry. Let me finish. What I mean by 'merging' is not 'swallowing'. Xuanbing Palace is still Xuanbing Palace, and you are still the Palace Master. Everything remains the same. It's just that in private, Xuanbing Palace and Tianyan Sect are one family."

"What's the difference between this and a merger?"

"There's a huge difference, Miss Leng. We still don't know who poisoned you. I've noticed signs that Lu Ya is colluding with the demons. Ye Qianqiu listens to Lu Ya, so perhaps he also knows Lu Ya's secrets."

Leng Rushuang fell silent. She was aware of some things, but the poison was controlling her.

Shen Yifei continued, "The Xuanbing Palace may seem fine now, but sooner or later it'll become someone else's prey. They're waiting for the perfect opportunity to take a bite!"

Leng Rushuang nodded. Back then, when that person came to coerce her into attacking the Tianyan Sect together, although she didn't actually participate, she didn't dare to refuse.

If there's a next time, who knows what the consequences will be?

"If the Xuanbing Palace were to merge with the Tianyan Sect, the situation would be different," Shen Yifei continued. "Although the Tianyan Sect isn't strong right now, I possess alchemy techniques that are unparalleled in the entire cultivation world, and a protective array capable of suppressing peak Tribulation Transcending cultivators. If that day ever comes, the Tianyan Sect will be your Xuanbing Palace's backing!"

After saying that, Shen Yifei took out ten bottles of top-grade pills from his storage ring, ten pills in each bottle, for a total of one hundred pills!

Leng Rushuang picked up a bottle of pills, opened it, smelled it, then opened it again, poured out a pill, and examined it carefully.

This man feeds his pet top-grade pills; he truly possesses extraordinary alchemy abilities.

Looking at the pills before her, Leng Rushuang fell into deep thought.

Although Shen Yifei's words were arrogant, they were not without reason.

She had long seen through Lu Ya's ambition.

The Demon Extermination Alliance is just a front; the real purpose is to use it to unify all sects in the world. As for whether it's colluding with the demons, Leng Rushuang believes that Shen Yifei is just making up a reason to swallow her up.

As one of the three major sects, Xuanbing Palace had long been a thorn in Lu Ya's side.

Rather than waiting for Lu Ya to make a move, it's better to find a backer first.

However, the backer in front of them is far too weak.

"Your cultivation has only just broken through to the mid-stage of the Mahayana realm. What makes you think you can protect the Xuanbing Palace?" Leng Rushuang asked.

"Because I am Shen Changtian's son."

"What? You're Shen Changtian's son?" Leng Rushuang stared wide-eyed at Shen Yifei.

The person in front of her was completely different from the peerless man in her mind; there wasn't even the slightest resemblance to him!

"Yes, I am Shen Changtian's son!" Shen Yifei nodded seriously and firmly.

"Your father was incredibly powerful. In that battle, he single-handedly fought against more than a dozen Tribulation Transcending stage experts from the Golden Crow Sect and the Myriad Swords Manor. That battle..."

Leng Rushuang's eyes were full of admiration, and Shen Changtian's image as a war god reappeared in her mind.

Shen Yifei didn't press her for details, but simply watched her quietly until she finished speaking.

"Countless corpses lay around your father, and half of the experts at the Tribulation Transcending Realm also died by your father's sword."

The scene of that great battle seemed to appear before Shen Yifei's eyes as well.

A man in white, using those three sword techniques, moved through the crowd as if it were empty, each strike carrying an unwavering determination.

Shen Yifei clenched his fist. He also knew those three sword techniques, but he hadn't grasped them yet and hadn't even scratched the surface.

Leng Rushuang continued, "At the last moment, your father was injured by a strange force, and that force definitely did not come from those people from the Golden Crow Sect! To this day, I still can't figure out who ambushed your father."

"Miss Leng," Shen Yifei took a deep breath, suppressing his thoughts, "I must avenge my father. Would you consider my suggestion again?"

Leng Rushuang lowered her head and pondered for a long time; this was a difficult choice.

But the man in front of me is definitely not ordinary.

His cultivation level isn't high, but he has many hidden cards. He doesn't have a wide network of connections, but he's quite resourceful.

More importantly, he made her feel the warmth she hadn't felt in a long time.

"Alright, I agree," Leng Rushuang finally spoke, "but on two conditions."

"You said, Miss Leng." Shen Yifei suppressed his overwhelming joy.

"First, the matter of Xuanbing Palace merging into Tianyan Sect should be kept secret for now. Lu Ya has spies all over the world, and if word gets out, Xuanbing Palace will immediately become the target of everyone's attacks."

"That's fine; our alliance should only be used in crucial moments. What about the second one?"

"Secondly, you must come to the Xuanbing Palace regularly to... to help me consolidate my cultivation level."

Shen Yifei was stunned for a moment, then burst into laughter.

This woman has finally seen the light.

"No problem, definitely!" Shen Yifei patted his chest and assured him, "I'll go to the Xuanbing Palace once a month, how about that?"

"No need, I came to Cangwu Mountain to find you. I'm afraid people will gossip about me," Leng Rushuang said somewhat embarrassedly.

The two of them finalized the alliance between the Tianyan Sect and the Xuanbing Palace right there in bed.
