The "Yin-Yang Immortal Essence Pill" - its effect: when yin and yang converge, it accumulates immortal essence.
"Yin and yang convergence?" Qin Ran read about the effects of this immortal pill, shaking his head. "Immortal essence?"
It wasn't entirely useless, yet wasn't completely useful either. After all, besides some secondary effects, the main purpose of this immortal pill was to increase one's chances of achieving immortality.
It seemed useful, yet wasn't really - firstly, he was merely a Golden Core cultivator, and achieving immortality was like taking just the first step of the Great Wall's ten thousand steps. Who knew when he would actually need the Yin-Yang Immortal Essence Pill? Secondly, even though his pill-refining skills had greatly improved, he still lacked the ability to refine immortal pills.
Thirdly, taking this pill required the convergence of yin and yang, which meant he needed a Dao partner.
But his avatar had traveled thousands of miles to reach the Celestial Sea Region - how the hell would he have a Dao partner? Most crucially, he wasn't even sure if he had "that capability."
"Looks like my original body will benefit from this..." He felt somewhat disappointed, but then another thought struck him. "Benefit my ass! That guy doesn't look like he could achieve immortality... Li Shiyin would be more suitable."
Who would ultimately benefit from this immortal pill remained uncertain, but there was a more pressing matter at hand. Which was...
This was a damn immortal pill!
An immortal pill!!
He couldn't refine it!!!
On the light screen before him, the Divine Essence Old Demon had very thoughtfully left just one slot, indicating that examinees only needed to refine one immortal pill to pass.
But there seemed to be a hint of mockery in this.
"The Divine Essence Old Demon himself probably couldn't even refine an immortal pill!" Qin Ran rolled his eyes.
He turned around and walked toward the desk in this pill-refining room.
He had learned the pill-refining techniques from the previous six rooms. The Heaven-Mending Pill room contained relatively basic techniques, and each subsequent room's techniques were more advanced than the last. The difficulty increased gradually from low to high - the Divine Essence Old Demon was being quite considerate.
[Translation continues due to length...]
Having studied diligently along the way, combined with his already decent foundation in pill refining, his current pill-refining skills had undergone a qualitative change compared to before.
With his current cultivation level, he could attempt to refine sixth-grade pills. In other words, his pill-refining ability was now limited by his cultivation level.
If his cultivation level were to increase, he should be able to refine most pills below immortal grade.
Therefore, unsurprisingly, this Yin-Yang Immortal Essence Pill room contained techniques for refining immortal-grade pills.
And again unsurprisingly, Qin Ran couldn't understand it. He encountered that situation where the text had characters, the characters had meaning, he recognized the characters, but couldn't comprehend what they meant.
To make an analogy, Qin Ran was like a brilliant middle school student who had self-studied high school material, but when faced with university-level knowledge, though familiar, it was incomprehensible.
After hesitating for a while, he still lowered his head and forced himself to read. It didn't matter if he couldn't understand - he would memorize it first. This was, after all, the technique for refining immortal pills.
Heaven finally showed mercy - the situation that Li Shiyin, Long Qiqi, Chasing the Wind, Tushan Youyou, and other Pill Peak disciples had faced before, he finally encountered today.
Just memorizing without seeking understanding took Qin Ran almost six days to completely record everything here.
After finishing the books, he still got up and went to the medicine cabinet to prepare the spiritual medicines for the Yin-Yang Immortal Essence Pill.
"The main ingredients are one Yin-Pole Dark Sea Lotus, five qian of Yang-Pole Lightning-Struck Rock, five liang of ten-thousand-year Chaos Golden Ginseng..." he muttered while gathering the medicines. "Supporting ingredients, two Blood Sea Gallbladders, Dragon Tail Whale tail..."
If these weren't spiritual medicines simulated by the sealed space, he wouldn't even be able to cut and separate the materials, let alone measure them accurately.
Finally, after preparing all the medicines, he started the furnace to refine the pill, but the first problem he encountered made him lose composure.
He threw the Yang-Pole Lightning-Struck Rock into the furnace's inherent celestial strange water, used his divine consciousness to activate the furnace, and then after half a day, the rock hadn't moved at all.
Forget about extracting the medicinal properties from the Yang-Pole Lightning-Struck Rock - this piece of stone hadn't shown the slightest change after soaking in the celestial strange water for half a day.
So Qin Ran knew that he could never refine this immortal pill.
If he couldn't even process the raw materials, how could he refine the pill?
"Is this how it ends?" He gave up on refining the immortal pill and returned to the light screen, reconsidering this test.
This was indeed a test, and passing it would bring extremely generous rewards. He had passed six stages consecutively, and although there were difficulties and setbacks, he had overcome them all and passed the tests, receiving rewards.
But...
Now that he was certain he couldn't refine an immortal pill, and there was no way to pass this stage, he had to face a problem:
How would he leave this pill-refining room? How would he escape this test? How would he leave this sealed space?
When he couldn't pass through the light screen, he realized that this pill-refining room was less like an examination room and more like a prison.
He wasn't a student taking a test; he was a prisoner trapped here.
Qin Ran took a deep breath and walked back to the light screen that had led him to this pill-refining room. After several attempts, he couldn't return to the previous room either.
He was trapped in this small pill-refining room.
Although... even if he could return to the previous room, or even the very first room, he still couldn't leave the sealed space.
"Am I going to die trapped here?"
Qin Ran realized this problem.
He suddenly found himself like a mouse in a jar. The mouse discovered rice in the jar and excitedly climbed in. It ate all the rice, then discovered a problem - it had reached the bottom of the jar, but the walls were too steep and slippery to climb out.
"How ridiculous have I become?"
He looked up and around at this small pill-refining room, which was about the size of a normal one. Like a prison cell, and also like...
"This square little room has become my coffin."
He couldn't help but laugh bitterly at himself. "A pill-refining room, dying in a pill-refining room, it's quite fitting. The Divine Essence Old Demon has quite a twisted sense of humor."
Qin Ran walked around the pill-refining room again and again, thoroughly checking every corner up and down, but found no mechanisms or secret doors.
The place was so small that no matter how much he tried, he couldn't find anything new.
He sighed and finally sat back down at the desk.
He took out the immortal pill-refining technique to read again, but couldn't focus anymore. It now seemed more like bait that had lured him into a trap rather than an immortal technique.
Putting down the book and looking around, he strangely thought of Brother Xun's iron room theory.
"Fortunately, I'm in my divine consciousness state, so I don't need to breathe and don't have to worry about suffocation," he smiled, then thought, "But because I don't need to breathe, I'll never think about breaking out of this iron room."
As he was smiling, he suddenly froze.
"Breaking the iron room..." Recently immersed in pill refining, and because of it, his mind wasn't working at full capacity. Only now did he react, "This..."
He would surely go mad, and then die in his madness. He knew this would be his final fate.
"So this was waiting for me!" Qin Ran despaired, lamenting, "I thought you, Divine Essence Old Demon, were a good person... you really are just a demon who toys with people's hearts!"
"Immortal pill..." he couldn't help but laugh coldly, "You, Divine Essence Old Demon, probably couldn't even refine it yourself."
"Ah..."
He collapsed to the ground, sighing.
But before he could finish sighing, he suddenly realized something:
"The Divine Essence Old Demon failed to ascend and died on Divine Essence Mountain!"
The Divine Essence Old Demon had died, which meant he must never have successfully refined the Yin-Yang Immortal Essence Pill!!
He jolted up and walked to the light screen, looking at the slot on it.
In the previous pill-refining rooms, each light screen had three slots. When he placed supreme-grade pills in them, the light screen would reward him with three real supreme-grade pills.
But here there was one slot, indicating that after successfully refining and placing an immortal pill, he would be rewarded with one immortal pill.
But...
The Divine Essence Old Demon himself didn't have an immortal pill, so what would he use as a reward?
Wasn't this contradictory?
There must be something wrong here!
Qin Ran raised his hand slowly, reaching toward the light screen...
His hand passed through the light screen without any resistance!!!
This light screen was different from the previous one - it was merely a layer of light with no blocking effect!
Great joy and sorrow, sorrow and joy, ups and downs, light at the end of the tunnel...
Qin Ran stood there, stunned.
At this moment, a deep and majestic voice echoed in his ears:
"Cultivation is an act of defying heaven! To defy heaven, you need the courage to challenge the heavens, to struggle against earth! You need the courage to break free from all mortal shackles! To become immortal, you must have the courage to reject all the golden rules left by those who came before!
"Young man, you need to be braver! You need more courage! Courage..."
Qin Ran knew this was the voice of Divine Essence Old Demon. It was his voice left within this light screen.
Standing there, he thought about his true self, or rather, himself...
He always thought too much, always hesitating and considering the consequences, lacking the courage to forge ahead. He was too timid. He lacked courage.
"Huff..."
Qin Ran let out a soft breath, stepped forward, and passed through the light screen.

ap a wealthy young lady? Or else I'll be eliminated by the system? Ye Feng, who awakened the Kidnapper System, originally wanted to live a peaceful life but never imagined he would become a kidnapper of young women. However, after some time, he discovered that all the girls the system ordered him to kidnap were far from ordinary. "Big brother Ye Feng~ You've kidnapped my heart, and now you're not allowed to leave me ever again~" "Ye Feng~ You kidnapped me back then, now it's my turn to capture you♡" "Little Feng, you're mine! You can only be mine!" "Ye Feng, none of them deserve you. Only I love you the most♡" ... This is madness, they've all gone mad! Wait, what? Why are all the girls I kidnapped yanderes?!

ive and Ruthless] Before his transmigration, Ye Xuan was playing a game called "Severing Emotions to Attain the Dao." The game's core wasn't about leveling up by fighting monsters, but about conquering various "bad women" with wicked personalities and cold, fickle natures. There was only one method to conquer them: stay unwaveringly by their side, then die at a critical moment, driving them to madness after losing the protagonist. The higher their level of regret, the higher the player's score. To dominate the server, Ye Xuan conquered all the bad women. In the early stages, he showered them with boundless tenderness, only to choose to sacrifice himself for them later, making them weep bitterly and drown in regret. Among them were: Xia Lengyue, the unfaithful immortal wife who chased after powerful men and discarded her husband like trash. Ye Qingcheng, the Demonic Venerable of the Joyous Union Sect, who appeared pure and innocent but was, in reality, promiscuous. Wu Lingxiao, the Empress of the Great Xia Dynasty, who lusted after men and loved maintaining a harem. Bai Qiangu of the Endless Demonic Sect: a bloodthirsty mass murderer. However, when the protagonist transmigrated into the game world, he made a horrifying discovery. Eight hundred years had already passed. The bad women he had conquered had now each become deities and revered ancestors. Faced with the endless stream of toxic women coming for him, Ye Xuan could only rely on his god-tier acting skills to carve a path of survival through this world of treacherous women.

Cheng's father told him he was getting remarried—to a wealthy woman. Cao Cheng realized his time had finally come: he was about to become a second-generation rich kid. Sure, it might be a watered-down version, but hey, at least he'd have status now, right? The wealthy woman also had four daughters!! Which meant, starting today, Cao Cheng gained four stunning older sisters?? But that wasn't even the whole story... "My name is Cao Cheng—'Cheng' as in 'honest, smooth-talking gentleman'!"

young master of the Shen family—a figure of immense power and wealth beyond measure—and awakened the "Destined Ultimate Villain System"! His starting scenario? Running into his icy fiancée who shows up with a mountain-descending divine doctor to break off their engagement. The divine doctor arrogantly taunts: "What does your Shen family have besides a bit of stinking money? You're not even worthy of tying Qingxue's shoelaces!" Shen Fei just smiled. He completely defied the usual script: "Fine, I agree to break off the engagement. Also, notify the finance department to withdraw all investments from the Su family." Minutes later, with its capital chain severed, the Su Group teetered on the brink of bankruptcy! The once aloof and proud ice queen CEO was thrown into utter panic. That very night, she went to Shen Fei's villa, casting aside all dignity to beg and plead desperately... From then on, in this world teeming with Sons of Destiny, Shen Fei embarked on a path of extreme dimensional suppression! A mountain-descending divine doctor? Peerless medical skills? Shen Fei: "Reporting you for practicing medicine without a license! I'll gladly take your ancient medicinal cauldron and twin sister assassins." The Crooked-Smiling Dragon King? Commanding a hundred thousand soldiers with a single order? Shen Fei: "Illegal assembly and suspected treason! Let a fleet of attack helicopters sanitize the area and teach you what the state apparatus really means!" A reborn tycoon? Knows all the golden opportunities of the next decade? Shen Fei: "A trillion in capital to reverse and pump the stock market, making you blow your margin and jump on the very first day of your rebirth!" What Chosen Ones? What bearers of Heavenly Fortune? In Shen Fei's eyes, they're all just chives (i.e., suckers/marks) waiting to be harvested! Shen Fei: "Sorry, but as the Destined Ultimate Villain, I don't play by the rules of honor. I only play the game of dimensional suppression."
