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

Only two people remained in the cave.

Although Bai Lu bit her lip, sobs still escaped from between her teeth.

She usually speaks coldly, but at this moment she was completely different from usual.

Shen Yifei was a little embarrassed. "Miss Bai, Leng Shanyue can hear us from outside."

"There's a soundproof barrier; she can't hear it."

No sooner had he finished speaking than Leng Shanyue's voice came from outside the barrier.

"What's the use of setting up a soundproof barrier! The fluctuations of your spiritual energy have collapsed half of the cave! Fathead Snake, if you're going to break through, can you please not make such a commotion?"

Bai Lu paused for a moment, looked down at Shen Yifei, and then looked in the direction of the cave entrance.

"There's a barrier around it, how can she still hear it?"

"Your spiritual energy fluctuations are probably too intense; even the barrier can't hold them back," Shen Yifei sighed. "Never mind her, let's continue."

Bai Lu bit her lip and remained silent this time.

The demon core in her dantian spun faster and faster, and cracks began to appear on its surface.

Shen Yifei could sense the change in her.

Suddenly, everything went black before his eyes, and he lost consciousness.

He didn't know how much time had passed, but when Shen Yifei opened his eyes, Bai Lu was smiling at him.

"Miss Bai...Miss Bai, you...you've broken through?" Shen asked.

"Yes, thank goodness you were here!"

Shen Yifei propped himself up and looked down. Thankfully, he was still a whole person.

The spiritual energy in his dantian had thickened again, and he was only one step away from breaking through the nascent soul.

Leng Shanyue leaned against the cave entrance, tossing a lotus seed in her hand, a smirk playing on her lips.

"Fathead snake, you really did break through to the Mahayana stage. I really underestimated you, no, I underestimated the thing under your body."

After Leng Shanyue finished speaking, he turned and left.

It walked so fast that its tail dragged on the ground, its fur standing on end, but it didn't care.

She walked to a flat rock, sat down with a thud, took out a handful of lotus seeds and stuffed them all into her mouth, chewing them with a crunching sound.

"Eat...eat, eat so much at once, you'll eat yourself to death." Bai Lu's voice drifted out from the cave.

"What business is it of my money what I eat? You've already reached Mahayana level, can't I even have a few lotus seeds to satisfy my craving?"

"You call that satisfying your craving? You're just being stubborn."

Leng Shanyue fell silent, looked down at the lotus seeds in her hand, and saw that there were three left. In a fit of pique, she ate the three seeds.

After crunching it, I closed my eyes and began to digest the spiritual energy of the lotus seeds.

Bai Lu helped Shen Yifei out of bed. "Come on, let's go out and see if that little vixen has broken through!"

The two reached the cave entrance. Leng Shanyue sat cross-legged on the ground with her back to them, her nine tails spread out on the ground. Her shoulders were trembling, and the red light at the tips of her tails flashed on and off.

Bai Lu noticed that Leng Shanyue's condition was not quite right; her shoulders were shaking violently, and her complexion was getting worse!

Bai Lu released Shen Yifei, took a step in front of her, and placed her hand on the Baihui acupoint on the top of her head. As her spiritual energy probed in, her expression changed.

"The spiritual energy is in such a mess, are you a pig? You swallowed all the lotus seeds in one gulp?"

Leng Shanyue tried to retort, but when she opened her mouth, she spat out a mouthful of blood. The blood was black.

"I... I had no idea that nine of them together would be so potent..." Leng Shanyue's voice trembled, and her lips had turned purple.

Bai Lu probed her dantian again, her brows furrowing even more deeply. The lotus seed's spiritual energy had formed a hard shell around her demon core, with chaotic true essence surging inside and a blocked shell on the outside. The true essence couldn't escape and was instead crashing into her heart meridian. At this rate, her heart meridian would be shattered in less than the time it takes for an incense stick to burn.

"Your spiritual energy is blocked and cannot be cleared by itself. I will use external force to help you clear it, but your demon core will also shatter."

Leng Shanyue gritted her teeth, "Go ahead, if it breaks, we'll fix it."

"You're talking nonsense. Your demon core is shattered, your cultivation level will regress to the Golden Core stage, and it will take you hundreds of years to cultivate back to the Nascent Soul stage. By then, I'll have already ascended to immortality. Who will be there to argue with you then?"

Leng Shanyue fell silent, her eyelids drooping, and her consciousness began to blur.

Bai Lu stood up and turned to look at Shen Yifei.

"Come here."

Shen Yifei was taken aback. "Me?"

"Her spiritual energy is blocked, and external forces cannot break through it; it can only be resolved from within. Your yang energy is extremely pure and can break through that shell by flowing outward from her body."

"Miss Bai, what exactly do you mean? I don't understand."

"Dual cultivation, I'll let you and her cultivate together."

Shen Yifei looked down at Leng Shanyue, who was curled up on the ground shivering, and then looked up at Bai Lu.

"Miss Bai, you want me to cultivate with her?? This... how can this be? My frail body can barely serve you, let alone serve her? You might as well kill me!"

"If you don't cultivate with her, I'll kill you! Then I'll kill myself! She can't survive anyway!"

After saying that, Bai Lu picked Leng Shanyue up from the ground, carried her into the cave, and placed her on the stone bed.

Leng Shanyue's body was burning hot, like a piece of red-hot iron, and his nine tails dangled off the edge of the bed, their tips charred.

Bai Lu turned around and looked at Shen Yifei, who had followed her in.

"What are you standing there for? Hurry up and take off your clothes."

"Miss Bai, is there really no other way? My vital energy is exhausted, and I'm out of supplies!"

Bai Lu ripped open Shen Yifei's belt.

"Even if we don't have the goods, we have to have them. Human lives are at stake, what are you pretending to be dead for?"

Shen Yifei clutched his waistband and backed away.

"Miss Bai, please be reasonable. I just finished serving you and haven't recovered my strength yet. You want me to fight again now? Isn't that going to kill me?"

Bai Lu reached out and pulled him back.

"I can see how much yang energy you have left in your dantian. Enough talk, take it off!"

Leng Shanyue curled up on the stone bed, trembling all over. His nine tails were charred, and he mumbled curses under his breath.

"Fat-headed snake... tell him to get lost... I'd rather die than cultivate with him..."

Bai Lu sneered, "Still being stubborn even when you're about to die. Your skinny frame is too good for him."

"Who are you calling ribs!" Leng Shanyue suddenly opened his eyes, and before he could finish speaking, he spat out another mouthful of blood.

Bai Lu pressed her back down.

"Save your energy, you'll be the one calling later."

Shen Yifei looked at Leng Shanyue, who was burning like a lump of charcoal on the bed, and then at Bai Lu.

"Miss Bai, is this really okay? Don't let someone get killed."

"Her spiritual energy is blocked; your yang energy is the only way to clear it. Should we go for it or not?"

Shen Yifei gritted his teeth and took off his clothes.

Leng Shanyue, her eyes half-open, saw Shen Yifei taking off his clothes and hurriedly tried to get up.

"Fathead Snake...you want him to go back in time...I'd rather explode and die than let him touch me..."

Bai Lu held her shoulder with one hand and tore her skirt off with the other.

"Even in this situation, you're still being picky."

Leng Shanyue was only wearing a bodice. Her collarbones were deeply sunken, and her ribs were clearly visible.

Shen Yifei glanced at it and subconsciously said, "It is indeed a bit thin."

Upon hearing this, Leng Shanyue, with a sudden burst of strength, kicked out.

"You think I'm too thin? You, a useless Golden Core cultivator, dare to say I'm too thin!"

Bai Lu pressed her legs down and turned to look at Shen Yifei.

"Shut up too. Get up here."
