The Devouring Demon God only let Yun Jin rest for a few hours.
The next day arrived.
Yun Jin was sitting cross legged, cultivating in silence.
A deep voice echoed in her mind. It was the Devouring Demon God.
She opened her eyes at once. Following the direction of the voice, she walked to a pitch black lake.
One projection of the Devouring Demon God was already waiting by the shore. He spoke calmly. "Jump in."
Yun Jin obeyed without hesitation.
The Devouring Demon God couldn't help showing a satisfied smile. She really was a genius of his clan, perfectly obedient. He loved how Yun Jin never wasted a single word.
The moment she dropped into the lake, an overwhelming surge of power rushed straight into her.
"This lake is filled with the purest demonic power. Absorb as much as you want. Once you drain the entire lake, your cultivation will probably break through to the peak of Tianmo," the Devouring Demon God said.
"Thank you, Demon God." Yun Jin replied with obvious joy.
The Devouring Demon God nodded with a slight smile. "The increase in demonic power isn't the most important part. You only need to come here for one hour a day. Ten years is enough for you to reach the peak of Tianmo. After an hour, I have other arrangements for you."
"Yes." Yun Jin answered immediately.
Power flooded violently into her body, every inch of her stinging with pain.
But this pain meant nothing to her.
While absorbing the energy, she asked curiously, "Demon God, why can I only reach the peak of Tianmo at most? If I could break through to Zhenmo, wouldn't that give us an even greater advantage?"
The Devouring Demon God slowly opened his eyes. He looked at Yun Jin with a hint of surprise. Soaking in this demonic spring, she didn't show even the slightest discomfort. Normal demonfolk who touched this for the first time would be screaming their lungs out.
But then he remembered Liu Yue, who had wandered outside for two thousand years. This child had probably suffered far more than anyone here could imagine. Compared to that, this pain must feel insignificant.
The Devouring Demon God became even more pleased. Talent like this, combined with a mind like hers, meant only one thing. She would definitely become someone great. So he treated Yun Jin with a bit more patience.
Hearing her question, he smiled. "I already told you yesterday. When Eternal Night descends, true power will sweep through this world. Without experiencing Eternal Night, you can't reach the Zhenmo realm. During Eternal Day, peak Tianmo is the limit."
Yun Jin's eyes flickered slightly.
The Polar Night Demon World was different from other worlds. It also counted twelve hours as a full day, but the entire day was always bright. There was no night.
Except for this Demon God Palace, everywhere else lived under eternal sunlight. This phase was called Eternal Day.
From what he said, after Eternal Day ended, Eternal Night would arrive.
And this small world was named the Polar Night Demon World. That meant one thing. Eternal Night was the true defining feature of this place.
After hearing the Devouring Demon God, she instantly understood. Without Eternal Night, no one could reach Zhenmo.
Eternal Night was the reason this small world was considered a first class small world.
"Demon God, when will Eternal Night arrive? And what exactly appears during it?" Yun Jin asked.
The Devouring Demon God was extremely patient with her. He smiled. "Eternal Day lasts three thousand years, Eternal Night lasts three thousand years. So your generation was all born during Eternal Day and none of you have experienced Eternal Night. Based on the cycle, it isn't far now. In about a thousand more years, Eternal Night will begin. When you were born, it was the shift between Eternal Day and Eternal Night. Your parents' deaths might be related to that."
He sighed softly.
He never cared how many other demonfolk died, but every death from his own clan was a true loss. Dying outside was far too pitiful.
Three thousand years of Eternal Day.
Three thousand years of Eternal Night.
Yun Jin memorized the timing, then focused on absorbing the energy again without asking more. She began calculating quietly.
There were still a thousand years before Eternal Night arrived in this world.
Converted to time in the Vast Azure World, that was fifty years.
After four years passed over there and the Sky City descended again, she needed to return to the Vast Azure World.
Once she took care of the hidden threat posed by that Immortal Emperor, she would return to the Polar Night Demon World and wait for Eternal Night.
Since only Eternal Night allowed cultivation to break through Zhenmo, the equivalent of the Jinxian realm, she absolutely couldn't miss this chance. To her, demonic power and spiritual power could convert freely. Becoming Zhenmo was equivalent to becoming Jinxian.
She had to reach the Jinxian realm, and not just that, but the peak of Jinxian. Only then would she be capable of confronting these Demon Gods head on.
After absorbing for a full hour, Yun Jin didn't stay longer. She rose from the lake and stood respectfully beside the Demon God's projection, waiting for his next instruction.
The Demon God opened his eyes with a faint smile. "You're very good."
Decisive, enduring, overwhelmingly talented. A future powerhouse gifted to the the Devouring Demon Clan by fate.
"Thank you for the praise, Demon God." Yun Jin responded respectfully.
The Devouring Demon God smiled again. "Sit."
Yun Jin sat cross legged without delay.
"The technique you're cultivating is the Heaven Devouring Soul Codex. Only members of our clan can cultivate it. You've done well with it," he said, pausing for a moment, "but it's meant for ordinary clan members. A true genius needs more than that."
Yun Jin's eyes shifted slightly.
To her, the Heaven Devouring Soul Codex was already overwhelmingly powerful. It had even helped her destroy the Life Tree's soul. Yet here in the Polar Night Demon World, it was considered something for ordinary clan members.
The gap between worlds was once again placed right in front of her. But she wasn't discouraged. She had only just arrived here. She had plenty of time to grow.
"Today, I'll give you a new technique. This one is modified from the technique I personally cultivate. It's perfect for you."
The Devouring Demon God tapped Yun Jin's brow. A flood of information rushed into her mind, forming a new cultivation method.
"Dark Star Codex."
He explained, "When cultivated to the extreme, it can break through the bottleneck and achieve Zhenmo. It's infinitely profound, but entering it is far harder than the Heaven Devouring Soul Codex. Don't rush. As long as you can grasp the basics within three years, that's already a success."
Yun Jin nodded.
Then she simplified it instantly. Good thing she had collected a lot of Emotional Value. This world drained Emotional Value way too fast.
Just simplifying this technique once cost her a hundred million Emotional Value. After simplifying twenty three times, she finally got a decent result.
[Simplified Dark Star Codex: Absorb one full day and one full night of darkness energy to enter the beginner stage.]
Darkness energy.
That was exactly the energy shrouding the Demon God Palace.
All she had to do was absorb it right here for one full day and one full night.
"In addition, I'll teach you a secret technique." The Devouring Demon God raised his hand again and tapped her forehead.
