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

Shen Yifei kept his word and immediately changed his target. He activated his spiritual energy, enveloped Ye Qianqiu, and then flames suddenly shot up.

"Ah..." Ye Qianqiu screamed in agony, writhing and struggling in the flames. "You little bastard! I'll kill you!"

"Master Ye, what do I have to be afraid of? Now I'll let you experience what it's like to be refined, and I guarantee you'll never forget it."

Ye Qianqiu was, after all, a peak Tribulation Transcending being, and even though he was seriously injured, his physical body was still incredibly strong.

Even after the flames had been burning for a long time, he was still able to struggle and curse.

"You little bastard! You wait! Alliance Leader Lu won't let you get away with this! The entire cultivation world won't let you get away with this!"

"Master Ye, save your energy. Look at your nephew, how quiet he is. Learn from him, so I don't have to do anything for him."

Ye Qianqiu struggled to look at Sun Huan, whose body was charred black and covered in blisters.

He was staring at him with terrified eyes, not daring to utter a word. Clearly, Ye Qianqiu's words had backfired, and he didn't want to repeat the same mistake.

And judging from the situation, his uncle's physique was more resilient than his, so he would be fine for the time being. After burning for so long, apart from burning off his clothes and singeing off all the hair on his body, he was still alright.

Ye Qianqiu tried to use his spiritual power to break free from the shackles of the mist, but the more he struggled, the tighter the mist became. Despite having the strength of a peak Tribulation Transcending cultivator, he was completely useless inside the furnace.

Shen Yifei continued to refine his spiritual energy for a while, and found that Ye Qianqiu's body was truly resilient. After the time it takes for an incense stick to burn had passed, only a few blisters had appeared on his body, without any serious injury.

This would take forever to master; the secret realm is only open for three days, and we haven't even done anything since we got in!

Shen Yifei recalled that the final fatal blow he delivered to Ye Qianqiu was caused by Hongxiu's blood essence stimulating the demonic energy within her body.

Try using demonic energy to refine him and see the effect!

Thinking of this, Shen Yifei looked inward at his dantian and found that the wisp of extremely dark demonic energy was no longer hiding. It was openly rotating slowly with the small vortex and looked much thicker than before.

He tried to mobilize some demonic energy, and the demonic energy was very obedient, slowly flowing into the furnace along with the spiritual energy!

Inside the alchemy room, the originally crimson flames instantly changed color, and the center of the flames turned black!

The moment Ye Qianqiu was enveloped by the flames, his whole body trembled violently, and he made a "hoarse" sound as if someone was choking him.

He felt completely different this time.

Although the flames were extremely hot and burned him until he was covered in blisters, he was able to withstand them thanks to his peak Tribulation Transcending body, so they did not cause him any real harm.

But the black flames didn't burn the surface; instead, they drilled directly into the gaps between his bones, rushed along his meridians into his dantian, and burned every inch of his spiritual power.

This pain was an internal, radiating pain. Ye Qianqiu could no longer bear it and rolled wildly on the ground, crying out, "What kind of fire is this! What kind of fire is this!"

Shen Yifei saw everything clearly from outside and was also startled.

The flames fueled by demonic energy were incredibly domineering.

"Brother, the demonic energy within you is incredibly powerful," Xinghe whispered inside the cauldron. "This fire doesn't burn flesh; it only burns spiritual energy. Once his spiritual energy is completely burned away, even the strongest physical body won't be able to withstand it."

Shen Yifei nodded, surprised that the demonic energy had such a powerful effect.

He continued to unleash his demonic energy, and Ye Qianqiu rolled and screamed in agony in the alchemy room.

Sun Huan, who was standing next to him, was huddled in the corner, trembling with fear. Looking at Ye Qianqiu's appearance, he was so scared that he didn't dare to breathe.

He kept praying in his heart, "Uncle, please hold on a little longer, just a little longer. Shen Yifei will get tired of training and forget about me..."

Unexpectedly, Shen Yifei seemed to hear the pleading voice in his heart, "Nephew, look at your uncle, he's much tougher than you. After I've finished refining your uncle, I'll refine you next. You two will be one after the other, so you won't be lonely on the road to the Yellow Springs. Oh, right, there's also your beautiful aunt, and your cousin Ye Wuhen, no, I should call him Ye Wugen... Haha, I'll give your whole family a chance to meet sometime."

Ye Qianqiu rolled and screamed in the alchemy room, his voice growing weaker and weaker.

The black flame burned slowly and steadily, like simmering a pot of old soup, requiring careful attention to the heat.

The physical body at the peak of the Tribulation Transcending stage was indeed resilient; it took almost the time it takes for an incense stick to burn before it began to show signs of melting.

"Uncle...you...you hold on...just a little longer!" Sun Huan watched as Ye Qianqiu's body slowly melted away like wax, and the last bit of hope in his heart gradually faded away.

Ye Qianqiu had no strength left to respond to him; he didn't even have the strength to roar.

Shen Yifei felt it was about time, so he separated a wisp of spiritual energy and ignited Sun Huan.

The only sound in the entire alchemy room was Sun Huan's screams, and then there was silence in less than half a cup of tea's time.

After another incense stick's time, Ye Qianqiu's physical body gradually turned into a ball of golden liquid under the burning of the demonic fire.

The liquid spun and condensed in the alchemy room, eventually turning into a golden pill the size of a longan.

Meanwhile, Sun Huan refined it into a gray pill.

Thus, Ye Qianqiu, the master of Wanjian Manor, the peak of the Tribulation Transcending Realm, and the vice leader of the Demon Extermination Alliance, was transformed into a top-grade elixir.

Shen Yifei put Ye Qianqiu's one into his storage ring and threw the other one to the little monster.

None of his women were willing to eat the human pills he refined. Although they could increase their cultivation, they were inherently resistant to them and preferred to consume other top-grade pills, even if it meant slower cultivation.

Shen Yifei's current cultivation level is already one foot in the Tribulation Transcending Realm. It is estimated that after consuming this pill, he will be able to break through.

He planned to go into seclusion to cultivate after leaving the secret realm, consume Ye Qianqiu, and break through to the Tribulation Transcending Realm!

Shen Yifei put the pills away and let out a long sigh of relief.

He almost lost his life in that battle.

If Hongxiu hadn't risked her life to transfer her essence and blood to him, activating the demonic energy within him, he might be the one lying on the ground now.

He recalled the words of the old man in hemp clothing. Could this be his impending doom? Was Hongxiu his benefactor?

He shook his head, thinking to himself, if the old man's calculations were accurate, this matter couldn't be this simple.

He glanced at the corpses of the Wanjian Manor elders on the ground, rubbed his fingers together, and black flames rose, setting their bodies ablaze.

After finishing, he looked around. The sky in the secret realm was gray and hazy, with no sun and no sense of direction.

The distant ruins were faintly visible in the mist, creating an indescribably eerie and sinister atmosphere.

Shen Yifei walked deeper into the secret realm. After about half an hour, he didn't see a single intact building along the way. Scattered skeletons were everywhere, and it was impossible to tell whether they belonged to humans or demons. Some skeletons still had weapons stuck in them, showing how fierce the battle had been.

Shen Yifei didn't see a single cultivator enter along the way, and he didn't know where they had all gone.

He could only wander around like a headless fly, going wherever he felt like, relying entirely on his instincts.

Soon, he spotted a palace ahead, which, although dilapidated, looked relatively intact.

As he approached, he discovered that the palace gates were open, and two skeletons were leaning against the gates, each stabbing the other through the chest with a sword.

Shen Yifei sighed, "The war between humans and demons is a fight to the death, what's the point?"

He stepped into the palace, and was startled by a statue in front of him as soon as he entered.
