"Thank you seniors for teaching you back then!" Du Fei arched his hand at Emperor Xuan.

Others may not know, but Du Fei understands that the magic suppression technique that Emperor Xuan taught him that day has allowed him to overcome countless dangers and benefit from it so far, which is not a small favor. What's more, after Emperor Xuan recovered today, the first thing he did was to force the Demon King away that day. Although he may not be afraid of the demon king the next day, if he wants to force him away, his strength at the moment is also beyond his strength.

"What I taught you is just a trick to suppress demons, but you have solved me from the seal for ten thousand years, if you really want to count it, I owe you more. Emperor Xuan shook his head and said in a deep voice.

Hearing this, Du Fei smiled and said slowly: "Senior, if you insist on saying this, it's not mine, why don't you even?"

"Hehehe, what a!" Emperor Xuan nodded, and then his gaze swept again, and when it fell on Du Fei, this time his eyes were full of appreciation.

"I didn't expect that with your strength, not only could you refine multiple Heaven and Earth Yuan Pills, but also, between shots, you would be able to make the cautious Demon King of the second day sense the crisis and take the initiative to withdraw...... Little guy, it seems that I was right back then, you are really not an ordinary person. Emperor Xuan was silent for a moment before he spoke again.

Although it is said that because of the matter of the demon king the next day, he can be regarded as being sealed for tens of millions of years, but Emperor Xuan has not been in vain all these years. At least he had killed countless extraterritorial heavenly demons back then, so at this moment, he could see that Du Fei had a restrained temperament, and this kind of temperament could only be possessed by the powerhouses of the extraterritorial heavenly demon clan who had killed him! Right now, this little guy who could only have an auxiliary position in the joint demon extermination back then already had the strength to kill the Heavenly Demon King head-on! Perhaps, among the extraterritorial heavenly demon clan, only the Nine Heavenly Demon King was a little bit of a threat to him.

"Senior praised ......" Du Fei shook his head, and then said with a little worry, "Senior, you just woke up from the seal at the moment, and you consumed your strength just now, will you?"

"It's okay, I'll naturally get back to my peak after a while, and I won't go to trouble those guys during this time, so you can rest assured. Emperor Xuan smiled faintly.

Hearing this, Du Fei was a little relieved. This Nine Emperors of the Flood Desolation is the pinnacle of combat power between heaven and earth, if the battle of annihilation is opened again, this Nine Emperors of the Flood Desolation is the last guardian saint of all beings in heaven and earth, and he finally rescued one by chance, if it falls inexplicably, then he doesn't know where to vomit blood.

"Besides, you don't have to worry too much about the other eight guys, I'll get them out one by one...... At the moment, I can sense the breath of the Heavenly Emperor and the Flower Emperor...... Emperor Xuantian's state is more troublesome, I will find a way to solve it after I recover, as for Emperor Hua, with your current strength, you may be able to rescue her, after rescuing her, you may be able to take her back to your Ling Tianzong to see. Emperor Xuan said with a somewhat meaningful taste.

Du Fei was slightly stunned, and only nodded slowly after a while, it seems that these Nine Emperors of the Flood Desolation are not ignorant of the seal.

After being silent for a long time, Emperor Xuan suddenly looked at Du Fei and said, "Then again, little guy, can you let me see your Heaven and Earth Yuan Dan?"

At this moment, Emperor Xuan's tone became a little gentler, after all, he knew that the Heaven and Earth Yuan Dan in Du Fei's body could be said to be his biggest hole card, and at this moment he proposed to see it, if the other party didn't give it, he couldn't do it.

When Du Fei heard this, he smiled, and then opened his mouth, and saw the reincarnation Yan Lei Dan appear in front of him, and the mark in Du Fei's hand changed slightly, and suddenly this reincarnation Yan Lei Dan flashed slightly, and it turned into six pills suspended in mid-air.

Seeing these Heaven and Earth Yuan Pills, even with Emperor Xuan's heart, he couldn't help but shrink his pupils slightly, and only after a moment did he sigh: "The second-ranked Yanshen Pill, the third-ranked Huangquan Reincarnation Pill, and the fourth-ranked Rongtian Pill...... Little guy, you got a lot of things, even if you were the realm lord back then, the opportunity was nothing more than that. If you look at the battle of annihilation, maybe the savior of this world is not us old guys, but you......"

When Du Fei heard this, he laughed silently, he knew his own strength, although there were many Heaven and Earth Yuan Pills in his body, but if he really started with the Nine Heavens Demon King, he might not be able to take advantage of anything.

"But speaking of which, I suddenly remembered a question," Du Fei pondered for a moment, then put away those Heaven and Earth Yuan Dan with a wave of his hand before he spoke, "I also know a lot about Heaven and Earth Yuan Dan, but I don't know what the number one Heaven and Earth Yuan Dan is...... I wonder if you can give me some advice?"

"The number one Heaven and Earth Yuan Dan?" Hearing this, Emperor Xuan was slightly stunned. After a while, he shook his head and said slowly, "Little guy, the number one Heaven and Earth Yuan Dan, even in the battle of world destruction, only the realm lord knows what it is, but the rest of us don't know what that thing is. However, before the realm lord fell into reincarnation, he had said that if the battle of destroying the world started again, then the Heaven and Earth Yuan Dan, which ranked first, might reappear!"

"The War of Annihilation will start again?" Hearing this, Du Fei was slightly stunned, and a look of doubt flashed in his eyes, but after thinking about it for a long time, he still shook his head, these things he couldn't understand for a while, after all, this was something that even the Nine Emperors of the Flood Desolation couldn't understand.

"If the War of Destruction of the World starts again, then, should we find the Realm Lord?" Du Fei was silent for a moment before continuing.

"Find out the Realm Lord?" Hearing this, Emperor Xuan smiled bitterly, "Back then, the Realm Lord sacrificed a lot in order to seal the Primordial Heavenly Demon King, and now she should be in reincarnation, maybe she doesn't even have a memory, how can we find it......? And if the war of annihilation starts again, we old bones will naturally not give up easily, but you young people, it's best not to give up easily......"

Speaking of this, Emperor Xuandi's eyes fell on the many admiring powerhouses in the rear, and then said lightly: "I have a suggestion for you, after you go out, let the old guys of the Eight Ancient Clans meet and gather the power of the Ancient Realm...... And I have a hunch that that day may not be too far away!"

"Yes!"

Hearing this, many strong people in the rear, including Hong Aya, Xiao Ran, Demon Hao and others, all responded in unison. In the presence of such beings, they have only the qualifications to be.

"Okay, I'm going to leave next, I need to find a place to recover my strength, but before leaving, I still need you to do something......" Emperor Xuan was silent for a moment before he spoke softly.

"What's the matter?" Hearing this, Du Fei was slightly stunned, and then said in a deep voice.

"In this tens of millions of years of sealing, I can vaguely perceive that part of the Primordial Heavenly Demon King should have been sealed under this by the Realm Lord back then," Emperor Xuan looked at the shattered darkness in the deepest part of the Realm Temple at this moment, and slowly spoke, "However, I don't have the Heaven and Earth Yuan Pill in my body, and it should be impossible to go in and find that part...... Therefore, I want you to go down and find that part, if you can destroy it, destroy it, if not, take it away, and don't let it fall into the hands of the extraterritorial Heavenly Demon Clan, because in that case, the strength of the Primordial Heavenly Demon King will be restored to perfection, then at that time, there may be no one in the heavens and the earth who is his opponent. ”

Hearing this, Du Fei pondered for a moment before gritting his teeth and saying, "Since the seniors have already spoken like this, then the juniors are duty-bound!"

"There's no hurry. Seeing Du Fei like this, Emperor Xuan smiled, "With your current strength, you may not be able to guarantee safety after you go down, and this world can't do without you...... So ......"

Speaking of this, it was a little bit of his right hand, and in an instant, he saw an extremely strange spatial fluctuation spread out, and then it was instantly wrapped around Du Fei's body.

"Spatial perception!?" A mysterious thought appeared in Du Fei's mind, making Du Fei slightly stunned, but in the next moment, he understood that this was a great opportunity given to him by Emperor Xuandi!

As soon as he thought of this, Du Fei no longer thought about anything else, but quickly sat down cross-legged and began to slowly comprehend.

Seeing Du Fei's appearance, Emperor Xuan also smiled and nodded. What kind of road Du Fei walked on, with his strength, he could naturally see clearly, so he also understood that in these matters, he could not give Du Fei even the slightest help. And the most important thing he should do is to let Du Fei comprehend the power of space a little faster, only if Du Fei's strength reaches a certain point, then it is possible for him to take the last step that the Nine Emperors of the Flood Desolation have not taken!

After staring at Du Fei for a moment, Emperor Xuan's gaze fell on Xiao Ran and the others, and then said with a smile: "The war of annihilation will start sooner or later, and you little guys will also be the main force in this world, today I will be a good person to the end, and help you!"

When the words fell, Emperor Xuan waved his hand again, and the Dao space perception permeated and wrapped around everyone's bodies. Seeing this, everyone sat down quickly with their knees crossed, and realized with excitement.
