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

Bai Lu slapped Shen Yifei on the back of the head. "Can't you think of anything else besides that thing?"

Shen Yifei rubbed the back of his head. "Sister, why did you hit me? You came at me yourself."

"You just slap me when I come close?"

"It wasn't intentional." Shen Yifei looked down and saw that the red mark on Bai Lu's face was becoming more and more obvious, looking like she had been whipped.

Leng Shanyue stood up from the pool, water droplets trickling down her skin, and walked up to Shen Yifei. "Bai Lu is right. If this thing could be used in battle, you could absorb your opponent's spiritual energy at will."

"So, the more I fight, the more energetic I get, and sooner or later I'll drain my opponent clean?"

"That's how it is in theory." Leng Shanyue sat back on the rock and picked up the folded clothes, putting them on one by one.

"But there are a few problems. First, can you control the rotation speed? If it's too fast, your meridians can't handle it; if it's too slow, you can't absorb it. Second, what do you do with the spiritual energy you absorb? If the other person's cultivation method clashes with yours, it will be poison to absorb. Third, if this thing gets discovered, what do you think people will think?"

Shen Yifei thought for a moment, "Would they think this is demonic magic?"

"That's right. The most taboo thing in the cultivation world is the cultivation technique that absorbs other people's spiritual energy. It's even more hated than demonic cultivation. If you use this technique in front of others, the whole world will know that you, Shen Yifei, are a monster."

Bai Lu had already put on her clothes and came over. "Don't listen to her trying to scare you. This thing is a treasure if used properly."

After Shen Yifei finished dressing, he said to Bai Lu, "Why don't you give me a try? Try hitting me with half your strength!"

Bai Lu raised an eyebrow. "Are you sure?"

She hadn't even had a chance to vent the anger she felt from being slapped, and Shen Yifei actually gave her one!

Seeing her unfriendly expression, Shen Yifei quickly said, "Sister, we agreed on 50% power, don't slap me in the face!"

Before he could finish speaking, Bai Lu raised her hand and slapped him.

Demonic power surged from his palm, pale green, and rushed straight towards Shen Yifei's chest.

Shen Yifei didn't dodge; instead, he used his spiritual energy to create a small vortex that spun around. Then, he reached out and caught the palm strike, palm to palm, as Bai Lu's demonic power collided with his.

A mid-stage Mahayana cultivator with 50% of their power would either smash a Nascent Soul cultivator into a pulp or severely injure them.

However, Shen Yifei has a strong physique and can withstand the strain, though he will definitely get injured.

However, as the vortex turned, Bai Lu's demonic power was directly absorbed into her dantian. In the blink of an eye, 20% of her demonic power disappeared, while Shen Yifei's body only received 30% of the attack!

He took two steps back, feeling a tightness in his chest, but his bones weren't broken and his internal organs weren't injured.

Bai Lu withdrew her hand, her eyes wide with surprise. "You...you really inhaled it?"

Shen Yifei examined his dantian internally. The 20% of demonic power had been shattered by the small vortex and mixed with the original gray mist in his dantian, making it impossible to distinguish between demonic power and demonic energy.

"It's been inhaled."

"How does it feel?"

"My chest feels a little tight, but otherwise I'm fine." Shen Yifei stretched his shoulders. "I absorbed a lot of your demonic power. If this stuff were used in actual combat, even a peak Nascent Soul cultivator might not be able to hurt me."

Leng Shanyue finished dressing and walked over, reaching out to press her hand on his dantian and feeling it. "There's more and more stuff in your dantian. Spiritual energy, demonic energy, and demonic power are all mixed together. I remember you almost exploded last time, but now you're perfectly fine."

"As I said, this is called 'the ocean embraces all rivers, and greatness lies in tolerance.'" After saying that, he glanced at Leng Shanyue's chest.

After being pampered a few times, the little fox became noticeably plumper.

Leng Shanyue withdrew her hand and snorted coldly, "If you put everything in there, there will be a time when you can't fit it all in."

"Then I'll have to trouble my two older sisters to help me expand, just like you," Shen Yifei pointed to Leng Shanyue's chest, "we'll expand each other's."

Leng Shanyue slapped him on the forehead.

Bai Lu laughed so hard she clutched her stomach. "Little fox, he's right, you really are much bigger here than before."

Leng Shanyue glanced down and blushed.

She used to wear white dresses with a flat chest area, but now at least she has curves. Although she can't compare to Bai Lu, she's infinitely better than before.

Shen Yifei chuckled twice. "Sisters, let's get serious. I've come to you this time to ask you to come out of retirement!"

"Where to?"

"Mount Cangwu?"

Bai Lu and Leng Shanyue exchanged a glance.

"Cangwu Mountain? Isn't that the territory of Tianji Pavilion?" Leng Shanyue frowned.

"This is my territory now." Shen Yifei briefly explained the merger, and also mentioned that the Heavenly Mystery Pavilion was a demonic cultivation sect. He didn't intend to hide it from the two demon kings.

After listening, Bai Lu said, "Little thing, you're quite something. You even managed to take down a demonic cultivator in the Tribulation Transcending stage."

Leng Shanyue didn't speak, her brows still furrowed.

"What are you worried about?" Shen Yifei asked her.

"Are you sure bringing us all together won't cause any trouble? The Qingyun Sect, the Hehuan Sect, the Blood Soul Sect, the Tianji Pavilion, plus the two of us demon kings. Can you handle all five groups together?"

"Don't worry, sister. Everything that needed to be suppressed has been suppressed; they're all mine now!"

After joking around, Shen Yifei said seriously, "Rebuilding the Tianyan Sect isn't just about putting up a sign. It needs people, it needs strength. Your five groups together number nearly a thousand. In the cultivation world, apart from the Golden Crow Sect and a few others, no one dares to underestimate this force. Given the chance in the future, I will destroy those three sects of the Golden Crow Sect!"

Bai Lu and Leng Shanyue exchanged a glance, both seeing surprise in each other's eyes.

This kid's ambitions are even greater than they imagined.

"Okay." Bai Lu nodded first. "I'll go with you. I'm tired of this lousy forest."

Leng Shanyue hesitated for a moment, then nodded.

The two women followed Shen Yifei back to Cangwu Mountain.

Bai Lu and Leng Shanyue flew side by side in front, with Shen Yifei following behind. Watching the backs of the two demon kings, he was overjoyed.

Bai Lu glanced back at him. "You've made arrangements for us? You're not going to make us share a room, are you?"

"Dream on." Leng Shanyue didn't even turn her head.

Shen Yifei chuckled, "One peak for each of you, right next to each other, so it'll be convenient for you two to visit and chat."

The three landed on the main peak of Cangwu Mountain.

Shen Yifei pointed to the two mountain peaks on the left, "Left Third Peak and Left Fourth Peak, they're next to each other, you two can choose. Left Third Peak is higher, with a better view. Left Fourth Peak is lower, but there are hot springs halfway up the mountain."

Without hesitation, Bai Lu chose the third peak on the left, and Leng Shanyue didn't compete either, choosing the fourth peak on the left. Knowing that Leng Shanyue liked taking baths, Bai Lu also offered the hot spring to her.

Shen Yifei led the two to their respective peaks, where he had prepared accommodations in advance.

The two of them weren't picky. They used to live in caves, but now they lived in much better places, especially the bed, which was big and soft.

Shen Yifei didn't announce Bai Lu and Leng Shanyue's visit to the mountain. These two mid-stage Mahayana demon kings were his trump card, something he wouldn't reveal unless absolutely necessary.

Shen Yifei didn't even tell Luo Qinghe and the others, which saved him a lot of trouble and made it easier for him to keep in touch.
