It took Cai Ying a full two days to finally complete the refinement of the Nether Pool Jade.

To Sect Leader Jiang's surprise, she wasn't killed by this treasure in the process.

The vast Power of Rules granted her countless insights.

It caused this Little Celestial Immortal's Rule Realm to skyrocket like a rocket.

From the initial entry level, she quickly ascended through small success, mastery, great success, all the way to perfection.

This was a level that many Demon Venerables couldn't reach, typically only Demon Kings could achieve it.

At the stage of Great Perfection, there will be a chance to advance to Quasi-Emperor in the future.

But this Sparrow Demon's Immortal Power Realm remained at Celestial Immortal, without any change.

"Unexpectedly, I inadvertently created such a unique character in you."

This indeed was a peculiar state.

The Nether Pool Jade of the Holy Hall was previously only used by Quasi-Emperors.

No matter how outstanding a genius is, one below the Quasi-Emperor had no right to such a Supreme Treasure.

Therefore, this was the first time in history that such a serious disconnection between cultivation and the Rule Realm had occurred.

Even Brother Cheng didn't know what she would become in the future.

However, she had already undergone noticeable changes at present.

According to Brother Cheng's understanding of her, after the refinement, this lively Little Sparrow Demon would definitely chirp on about her feelings, followed by throwing various common sense questions at him.

Yet this time, she merely sent a solemn message: "Thank you, Demon Lord, for your nurturing!"

Afterward, she fell into silence.

Her face was still the same face, her eyes still the same eyes.

But the sweetness and naivety of before were completely gone; only coldness and indifference remained, as if she were a different person.

She slowly surveyed everything around her.

The Guma Quasi-Emperor, on the other hand, was elated; she hadn't died, meaning he too wouldn't die.

"Hahaha, great news!"

"I thought you were dead for sure, but didn't expect your luck to be so great to pull through..."

Before he could finish, he clutched his head and flew skyward.

Because Cai Ying, with a single thought, inflicted her contract-bound suffering onto him, causing him immense pain and screams.

A moment later, he landed back on the ground, his face ashen and significantly weakened.

"Wh-why..."

Cai Ying cut him off expressionlessly: "I did not instruct you to speak, so do not open your mouth."

The Guma Quasi-Emperor looked at her in disbelief, completely unable to believe those words had come from her.

He had seen what this Little Celestial Immortal was like before.

Frankly speaking, even if an enemy lay at her feet, she couldn't bear to step on them and would rather help them up.

And now...

Brother Cheng, in the sword scabbard, was likewise astonished.

What's going on here?

Has this Little Sparrow Demon's temperament changed?

Could it be due to the effect of the Nether Pool Jade?

This time, he guessed correctly.

The Nether Pool was the origin of Demon Qi in the Demon Realm; treasures produced there naturally carried some unique influences.

Simply put, it made a person more like a typical demon cultivator.

Brother Cheng's first reaction was anger; just look at you, this little punk trying to turn dark?

He wished he could slap her against the wall.

But on second thought, after such a transformation, the Little Sparrow Demon's saintly attribute was gone, wasn't this exactly the result he desired?

"Demon Lord, was this all your doing?"

She looked at the scattered Quasi-Emperor corpses in the distance, her expression unchanged, as if they were just clumps of grass.

Brother Cheng felt slightly gratified; at least she still maintained respect for him.

"What else?"

"As expected of the Demon Lord, they should be dealt with ruthlessly!"

She praised him and then went to collect the spoils of war without needing Brother Cheng's reminder.

Her actions were as rough as could be, stripping the Quasi-Emperors bare, giving each a final stab to make sure they were dead.

After finishing up, she tidied herself and then ordered the Guma Quasi-Emperor to lie down.

Ignoring his reaction, she stood on his back.

"Alright, continue flying forward." She ordered coldly.

The Guma Quasi-Emperor was crestfallen; was he being treated as her mount?

Brother Cheng in the sword scabbard twitched his mouth.

Isn't this change too extreme, too thorough?

"You've already acquired the Promotion Jade Talisman and the most valuable treasures of this battlefield, what more do you want to do?"

The Guma Quasi-Emperor took off in a prone position, and Cai Ying, standing on his back, was surprised to hear Brother Cheng's transmission: "You're planning to stop here?"

"What else?"

"I counted, there should be at least fifty more Quasi-Emperors from other battle zones on this battlefield." Cai Ying's eyes carried a hint of slaughter.

"And then?" Brother Cheng was noncommittal.

"Aren't you going to kill them all?"

"That's not the plan."

Brother Cheng was always lazy, having completed the designated task, he was too lazy to complicate things further.

Most importantly, with his current strength and status, there was no need to chase Quasi-Emperors all around.

Cai Ying's murderous expression turned into disappointment.

"Have you become merciful?"

Poof!

Brother Cheng almost spat out water if he had a body.

"What did you just say?"

"I was wrong, I shouldn't have spoken carelessly."

"I'm merciful?"

"I dare not say so."

"Huh? When did it become your turn, Little Saint, to call me merciful?"

"Please forgive me, Demon Lord..."

Considering her sincere attitude in admitting her mistake, Brother Cheng let it slide.

Standing on the human-shaped flying carpet, Cai Ying soon encountered Quasi-Emperors from other battle zones.

Seeing the peculiar combination of a Celestial Immortal and a Quasi-Emperor, especially given this curious stance, those Quasi-Emperors were naturally bewildered.

And upon seeing that the Guma Quasi-Emperor was merely early-stage Quasi-Emperor and visibly weakened, it was unsurprising when they attacked.

This was the "pure and honest" Demon Realm; when seeing an isolated and weaker demon cultivator, their choice was often to strike while they were down.

While Brother Cheng was unwilling to proactively slaughter everywhere, when the opposition charged, he certainly wouldn't hesitate.

An Immortal Soul impact and several more corpses fell from the sky.

"The Demon Lord is invincible in the universe, eternal through the ages, uniting the Six Realms!" Cai Ying's voice carried a hint of fanaticism.

Perhaps, in her eyes, Jiang Cheng was the totem of all demon cultivators, after all, the First Demon of the Six Realms.

Well, the complimenting capability remains intact too.

Brother Cheng expressed satisfaction, not having pampered her in vain.

After vanquishing two more waves of Quasi-Emperors, the three-day mark for the battlefield's opening came, concluding the first round.

The sign-up marks on every participant lit up, and then a force of absorption came forth.

Everyone vanished from their positions, reappearing at the altar where they had initially signed up.

Three days were but a blink for demon cultivators, and the place was still crowded, with Lie Yu Quasi-Emperor and other Saint Hall Demon Kings waiting.

Seeing figures appear simultaneously on the altars from the Profound Immortal Group to the Chaos Group, the scene erupted once more.
