At this moment, the Holy Son and the other seven Flying Sky Yin Monkeys were already communicating via Sound Transmission, discussing how to find an excuse to come out after returning to the Underworld, and then follow Ye Yunfei.
Because Ye Yunfei's command to them was to try and exit the Underworld as quickly as possible after returning.
This Holy Son was now an Earth Immortal, and the other seven Flying Sky Yin Monkeys were all True Immortals. Their strength was not weak, and they could already be of some help to Ye Yunfei.
Moreover, these Flying Sky Yin Monkeys were creatures of the Underworld; ordinary forces were unwilling to provoke them. Therefore, having them run errands would be quite convenient.
Because provoking the Holy Son of the Flying Sky Yin Monkeys was equivalent to provoking the entire Flying Sky Yin Monkey Tribe!
"And there's one more!"
At this time, within that Small World, Ye Yunfei said to himself.
"Everyone, rest here a little longer for the time being."
Ye Yunfei gave instructions to the members of the 35th Battalion, then returned to the Phantom Tower.
Ye Yunfei came before a Heart-Devouring Demon and stared at him coldly.
This Heart-Devouring Demon had wanted to sabotage Elder Zhuo's breakthrough not long ago, but was discovered by Ye Yunfei, who captured him.
"Despicable human brat, release me immediately, or I'll have it out with you!"
The Heart-Devouring Demon was already sealed, unable to move his entire body. He glared furiously at Ye Yunfei, roaring fiercely.
"Heh heh... Now that you've fallen into my hands, forget about escaping.
It's still those two choices. First, death. Second, form a Heart-Oath and submit to me.
Choose. I don't have much patience."
Ye Yunfei said calmly.
"Brat, you humans are a lowly race! To imagine our Heart-Devouring Demon Tribe submitting to you is impossible!"
The Heart-Devouring Demon bellowed in rage.
Hiss! Hiss!
Without another word, Ye Yunfei directly unleashed the Formless Heart Sword and Soul Sword, simultaneously attacking the demon's Soul Sea, aiming for his Soul Body.
Aah... Aah…
The Heart-Devouring Demon was already sealed. Despite possessing an Earth Immortal cultivation, he couldn't exert most of his strength. Having little power to resist, he could only let out successive miserable screams under Ye Yunfei's assault.
Next, Ye Yunfei employed every method at his disposal to torture this Heart-Devouring Demon. Terrifying torment and unbearable, intense pain drove the demon to question his very existence, and he finally relented, agreeing to form a Heart-Oath and submit completely to Ye Yunfei.
Thereafter, Ye Yunfei and the Heart-Devouring Demon performed the Heart-Oath.
"How is this possible? Your Soul Force Energy is actually so powerful!"
After the Heart-Oath was formed, the Heart-Devouring Demon discovered that Ye Yunfei's Soul Force Energy was actually stronger than his own, leaving him utterly shocked.
It turned out that the Heart-Oath had a backlash effect. After establishing the oath, if the controlled party's Soul Force Energy far surpassed that of the controller, it was possible to reverse the control.
That's why, before forming the Heart-Oath, this Heart-Devouring Demon had harbored a sliver of hope, thinking his Soul Force Energy might be stronger than Ye Yunfei's. He planned to find an opportunity to reverse-control Ye Yunfei after the oath was made. However, the result revealed that Ye Yunfei's Soul Force Energy level was not the slightest bit weaker than his—if anything, it might be stronger.
And so, Ye Yunfei had gained another slave with Earth Immortal strength!
"Tell me about the current situation in your Demon Realm."
Ye Yunfei spoke up.
"Many members from our Demon Realm have already ventured out, operating within the Three Thousand Major and Minor Worlds.
However, our Demon Lord has given the order that our Demon Realm should not get involved in the war between the Dark Faction and the Light Faction for the time being. Instead, we should take the opportunity to expand our territory, occupy a batch of Small Worlds, and broaden our Demon Realm's domains.
As far as I know, it's not just our Demon Realm. The Demon World, the Netherworld, and some other powerful, special worlds are doing the same. They all intend to take advantage of the fierce conflict between the Dark Faction and the Light Faction to seize as many worlds as possible within the Three Thousand Major and Minor Worlds as their territory."
The Heart-Devouring Demon replied.
"Hmm."
Ye Yunfei nodded.
In fact, Ye Yunfei had long since guessed this was a possibility.
"How strong is your Demon Realm?
What exactly is the cultivation of that Demon Lord?"
Ye Yunfei thought for a moment, then asked.
"As far as I know, our Demon Realm has a group of ancient demons who cultivate in seclusion year-round. Most of them are Earth Immortals.
As for what level the Demon Lord is, I do not know.
Within the Demon Realm, the Demon Lord's status is extremely high. Even our Earth Immortal experts rarely get the chance to meet him.
What his exact strength is, I truly do not know. Not just me, I believe most Earth Immortals in the Demon Realm don't know either. Only a few close aides who frequently interact with him would likely know his true strength."
The Heart-Devouring Demon pondered for a moment before speaking.
"I see.
Then, do you think it's possible the Demon Lord is a Golden Immortal?"
Ye Yunfei nodded and asked.
"Golden Immortal?
I have never heard of any Golden Immortals existing within our Demon Realm. Whether the Demon Lord could be one, I really don't know."
The Heart-Devouring Demon hesitated for a moment before answering.
"Hmm."
Ye Yunfei nodded and didn't press further.
Although this Heart-Devouring Demon was an expert at the Earth Immortal level, his combat power wasn't actually very strong. His status within the Demon Realm was likely not very high, so the extent of his knowledge might be limited.
"Chief Ye, how should our 35th Battalion proceed next?"
After Ye Yunfei subdued the Heart-Devouring Demon and exited the Phantom Tower, the five Elders of the 35th Battalion gathered around him. It was Elder Chi who spoke up to ask.
"We carry on.
Right now, our Light Faction and the Dark Faction are at war. Our 35th Battalion is part of the Light Faction. We have no reason to be idle."
Ye Yunfei considered for a moment before replying.
The World-Ending War had already begun in earnest. The 35th Battalion was one of the thirty-six battalions of the Light Faction, and Ye Yunfei, as its chief, couldn't possibly have the battalion hide away during wartime.
"Set out. Continue!"
Ye Yunfei gave the order. He gathered the troops and, with a wave of his hand, led the men of the 35th Battalion, preparing to leave this world.
Just at that moment.
An elder walked into this world, arriving before Ye Yunfei.
"Ye Yunfei, Senior Chu has entrusted me to bring you a message."
The elder spoke directly.
"Is it news about Elder Di Ming?"
Ye Yunfei's spirit was stirred, and he immediately asked.
Last time, Old Man Chu had told Ye Yunfei that he would notify him immediately if there was news about Di Ming.
So, upon hearing the elder's words, Ye Yunfei immediately guessed what it was about.
"Yes.
There is now evidence confirming that Di Ming has already entered the Colorless Abyss."
That elder nodded.
"Senior Chu's intention is, if you want to go to the Colorless Abyss, he'll have me temporarily replace you as chief of the 35th Battalion.
I believe my strength should be barely adequate to temporarily serve as the 35th Battalion's chief."
The elder continued, nodding.
As soon as his words fell, a powerful aura of energy erupted from within the elder's body.
High-level Earth Immortal!
Moreover, this elder's strength was clearly much greater than newly advanced High-level Earth Immortals like Elder Qi and Elder Zhuo.
"Very well. Since there's news of Elder Di Ming, I shall make a trip to the Colorless Abyss."
Ye Yunfei thought for a moment, then nodded in reply.
A portion of those closely connected to Ye Yunfei were still missing. Without finding them and bringing them back, Ye Yunfei could not rest easy, for, in a sense, those people had suffered their plight precisely because of their ties to him!
