"I won't deceive you."
The Heart-Devouring Demon nodded repeatedly.
At this moment, all he wanted was to stay alive.
This human youth before him was far too fierce. He knew that if he failed to satisfy this young man, the other would undoubtedly kill him.
"The fighting seems to have stopped!"
Just then, the three elders of the Celestial Gold Race noticed that the battle between Ye Yunfei and the demon had ceased. Their spirits immediately lifted.
At that moment, the Heart-Devouring Demon was telling Ye Yunfei how to establish the Heart-Oath.
Of course, Ye Yunfei had not yet fully trusted the Heart-Devouring Demon's words. He remained on high alert, prepared to strike and kill instantly if he noticed anything amiss.
However, the Heart-Devouring Demon did not dare to try any tricks. In the end, he and Ye Yunfei successfully established the Heart-Oath.
A profound rune materialized between Ye Yunfei and this Heart-Devouring Demon.
"So this is the Heart-Oath," Ye Yunfei said as he waved his hand, drawing the rune before him.
Ye Yunfei felt that he could completely control this rune, and through it, he could control the life and death of that Heart-Devouring Demon!
"Master!"
The Heart-Devouring Demon stood respectfully before Ye Yunfei, calling out weakly.
At this point, the Heart-Devouring Demon was extremely feeble, his face deathly pale.
He had been shattered over a dozen times by Ye Yunfei earlier and had been continuously assaulted by Mental Force energy. His foundational essence had been severely depleted.
If it weren't for this, he wouldn't have swallowed his pride and been willing to become Ye Yunfei's slave.
"Your injuries are so severe, recovering will likely not be easy," Ye Yunfei said, frowning as he looked at the dispirited Heart-Devouring Demon.
When they were enemies, Ye Yunfei naturally went all out to deliver killing blows. Now that this Heart-Devouring Demon had become his slave, Ye Yunfei hoped he could become a bit stronger.
"Master, my injuries are indeed quite severe. Our Heart-Devouring Demon race uses various negative emotions as our energy. If I can obtain a large amount of negative emotions, I can quickly recover my strength," the Heart-Devouring Demon replied.
"Where would I find a large amount of emotions for you? Let's talk about it later," Ye Yunfei said, shaking his head upon hearing this.
"You may not be aware, Master, I always carry a significant amount of previously collected negative emotions with me. After refining those negative emotions, I can recover from part of my injuries," the Heart-Devouring Demon said.
"Good. Enter my spatial magic treasure and focus on recovery," Ye Yunfei nodded.
"Yes, Master," the Heart-Devouring Demon nodded in agreement.
"Wait. Did you come from the Demon Realm?" Ye Yunfei suddenly asked.
"Yes, Master, I came from the Demon Realm," the Heart-Devouring Demon answered.
"The Demon Race from the Demon Realm generally didn't emerge easily in the past. Why have they started coming out so suddenly lately?" Ye Yunfei questioned.
The strength of this Heart-Devouring Demon before him was not weak; he should know quite a bit about the affairs of the Demon Realm.
"Master, it's the Demon Monarch who ordered us to come out. The Demon Monarch said the Three Thousand Major and Minor Worlds are about to plunge into an unprecedented age of great chaos. He commanded us to come out and move about, taking advantage of the chaos to disrupt the order of the Three Thousand Major and Minor Worlds. Moreover, many of us demons in the Demon Realm naturally feed on the flesh, blood, and life-essence of various races' beings. Even if the Demon Monarch hadn't ordered it, many would sneak out to hunt for sustenance. Like our Heart-Devouring Demon race, we use the negative emotions of living beings as our cultivation resource. Many members of our race have already infiltrated the Three Thousand Major and Minor Worlds, roaming everywhere to collect negative emotions and inner demons from living beings. Also, from what I know, it's not just our Demon Realm. Many members of the Demon Race from the Demon Realm have also come out and are moving about within the Three Thousand Major and Minor Worlds. Many members of the Demon Race are similar to us demons, feeding on the flesh, blood, and life-essence of living beings in the world," the Heart-Devouring Demon answered.
"The Demon Monarch ordered you to come out and disrupt the order of the Three Thousand Major and Minor Worlds?" Ye Yunfei couldn't help but frown upon hearing the Heart-Devouring Demon's words.
Ye Yunfei could understand members of the Demon Race and Demon Race emerging on their own to prey on other races. It was true that many demons and demons fed on beings of other races. But the Demon Monarch commanding the demons of the Demon Realm to come out and disrupt the order of the Three Thousand Worlds—this was something Ye Yunfei couldn't comprehend.
"Why does the Demon Monarch want to disrupt the order of the Three Thousand Major and Minor Worlds?" Ye Yunfei asked.
"I don't know about that. Matters concerning the Demon Monarch are not something I can inquire about," the Heart-Devouring Demon replied.
"So that means many members of the Demon Race from the Demon Realm have already entered the Three Thousand Major and Minor Worlds and are moving about?" Ye Yunfei thought for a moment and asked another question.
Ye Yunfei recalled the last time he battled the Demon Race within the Three Thousand Major and Minor Worlds. In the end, a Transcendent-level powerhouse from the Demon Race had taken action against him. At the critical moment, thankfully, the Ancient Agreement intervened and resolved the crisis for him.
"Yes, Master. I've been out of the Demon Realm for some time now. During this period, I've encountered quite a few members of the Demon Race," the Heart-Devouring Demon nodded in response.
"First, enter my spatial magic treasure to heal," Ye Yunfei said, teleporting the Heart-Devouring Demon into the Phantom Tower to recuperate.
Then, with a flash of his figure, Ye Yunfei arrived before the three elders of the Celestial Gold Race.
"Fourth Elder, congratulations on your successful breakthrough," Ye Yunfei said with a smile as he looked toward the Fourth Elder.
"My thanks to you, Young Master Ye, for protecting me during the tribulation and resisting the demon race. Otherwise, I would surely be dead at the hands of that demon now," the Fourth Elder said gratefully.
"By the way, Young Master Ye, what happened to that demon?" the Great Elder suddenly asked curiously.
"Do not worry, Great Elder. That demon has been subdued by me," Ye Yunfei replied with a smile.
"Young Master Ye's methods truly border on the divine!" the three elders of the Celestial Gold Race exclaimed in admiration.
When that demon descended earlier, all three of them had been suppressed to the point of barely being able to move.
Such a powerful demon had actually been subdued!
"The Third Elder and Fifth Elder should be close to breaking through as well," Ye Yunfei thought, sending his Soul Power perception into the Phantom Tower.
Boom! Boom! Boom!
Dark clouds suddenly gathered densely in the high sky, and tribulation lightning continuously manifested.
"It's the Third Elder's Lightning Tribulation! The Third Elder is about to break through!" Ye Yunfei realized and spoke out.
In the next moment, the Third Elder emerged from the Phantom Tower and began to undergo his Lightning Tribulation.
Ye Yunfei stood nearby, releasing his Soul Power to sense the situation in this area, providing protection for the Third Elder.
Earlier, during the Fourth Elder's tribulation, that Heart-Devouring Demon had suddenly appeared to cause trouble. Ye Yunfei was worried the same thing might happen.
Several hours later, the Third Elder's Lightning Tribulation concluded successfully!
Subsequently, the Fifth Elder also rushed out from the Phantom Tower and began his Lightning Tribulation.
Half a day later, the Fifth Elder successfully passed his tribulation!
"Great Elder, your Celestial Gold Race now has five Heavenly Emperors," Ye Yunfei said with a smile.
"Haha... Yes, compared to the past, the overall strength of our Celestial Gold Race has increased significantly," the Great Elder answered excitedly.
