Li Muran asked curiously, "The nameless predecessor recognized the origin of this heavenly demon blood?"

"I'm not sure yet!" Zhao Wuming said: "Zhao has to refine some more Heavenly Demon Blood before he can be sure of this matter!

With that, Zhao Wuming continued to dip the Heavenly Demon Blood with the Afterlife Flower, absorbing the Heavenly Demon Blood and refining it. Li Muran and the other four immortals set off and flew back to Youran Palace.

Halfway through, Zhao Wuming said to Li Muran: "Zhao has repeatedly determined that this heavenly demon blood has a great mystery!"

"Please say it clearly!" Li Muran's heart sank.

Zhao Wuming said: "This heavenly demon blood is a little mixed, which is mainly the blood of the ancient demon beasts, but Zhao also found that this is not an ordinary blood cry, its blood actually has yin and yang two qi at the same time, and this yin and yang two qi are from the yin and yang two immortals in the thirteen immortals of the last days!"

"What?" Li Muran was shocked: "The blood of the Heavenly Demon is actually related to the Thirteen Immortals of the Last Days?!"

"I'm afraid it's not a small relationship!" Zhao Wuming said: "The Great Elder of the Heavenly Demon Sect has the Heavenly Weapon Rune of the Artifact Refining Immortal Pot, this artifact was originally controlled by Yang Immortal Mu, and the Heavenly Demon Holy Blood taken out by the Great Elder actually has the breath of Yin and Yang Two Immortals, which shows that the Heavenly Demon back then must be related to the Yin and Yang Two Immortals!"

"Back then, the two immortals of Yin and Yang also went to the Origin Realm, and the two of them were also uncertain about their life and death, why they were related to the Heavenly Demons, this is really strange! But one thing is for sure, there must have been a catastrophe in the Origin Realm, and the four immortals who went to the Origin Realm at that time were all unable to save their lives, so they used their respective supernatural powers to escape. ”

"The Ice Wind Daoist escaped with the Golden Feather Daoist's Open Heaven Axe and came to a certain place in the Barbarian Immortal Domain of the Immortal Domain here, but because he was seriously injured and unable to recover, he hurriedly left the inheritance and hid in the Nether Realm with the Open Heaven Axe, lest the Open Heaven Axe fall into the hands of other immortals. ”

"The life and death of the two immortals of yin and yang are also unknown, but there must be a lot of fierceness, and their breath somehow came to this immortal realm, and fused with a blood crying demonic beast that had at least the cultivation of a mixed yuan golden immortal, creating a heavenly demon of the level of immortals with extraordinary powers. But this Heavenly Demon was quickly suppressed and killed by the Immortals, leaving only some scattered bloodline inheritance, which is now the Heavenly Demon Sect!"

"Among the four immortals who went to the Origin Realm back then, these three immortals have already suffered a catastrophe of life and death, and the whereabouts of the Golden Feather Daoist are unknown. And Jin Yu's mount, Qi Qi, said that it was Jin Yu who ordered the destruction of the Origin Realm, and there must be another mystery in this!"

"What happened in the Origin Realm back then?" Zhao Wuming muttered, but unfortunately he was in reincarnation at that time and didn't know anything about it!

"I hope we can resurrect the Ice Wind Daoist as soon as possible, and then we can learn the truth about the past!" Zhao Wuming sighed.

Li Muran informed the two immortals of the Ice Fairy and Phantom Ling'er about the matter of the Heavenly Demon Blood, and the two immortals were also shocked. The immortals discussed, and they must try to infiltrate the Heavenly Demon Sect to find out what the relationship between the Heavenly Demon and the Yin and Yang Immortals is.

Li Muran suddenly said: "After the original origin realm disappeared, the inheritance of the Ice Wind predecessor appeared in this Void Sun Immortal Domain, and the breath of the two immortals of Yin and Yang also appeared in this Immortal Domain; Qi Qi also appeared in the subordinate interface of this Immortal Domain; even the reincarnation of the nameless predecessor was also in the subordinate interface of this Immortal Domain. Isn't this enough to show that the Origin Realm has not completely disappeared, and its remnants have been integrated into the Void Sun Immortal Domain for some reason, so the mounts, breaths, treasures and other things of the Four Immortals are also scattered all over the Void Sun Immortal Realm?"

"Very likely!" Zhao Wuming agreed with Li Muran's statement: "Did Li Xiaoyou think of a certain place?"

"Outside the Heavens!" Li Muran said: "That Outer Heaven in the Nether Realm has hidden mysteries, and it is very likely to be related to the Origin Realm! Huoyun and Nirvana, either from the Outer Heaven or reborn in the Outer Heaven, they must know a lot of secrets of the Outer Heaven. If you can meet these two people, maybe you can even unlock the secrets of the Outer Heaven and the Origin Realm! Counting it, these two people should have already ascended to the Immortal Realm, and they have already ascended to this Void Sun Immortal Realm! However, the Void Sun Immortal Realm is so wide, unless they are all in the Flying Ascension City, it is really not easy to find!"

"There are still a few months left before the Ten Thousand Immortals Conference, why don't I return to Feixian City and see if I can find these old people!"

After Li Muran informed the Ice Fairy and the others of his proposal, both the Ice Fairy and the Phantom Ling'er agreed. Although Shan Feng didn't understand the reason, since Li Muran and the three immortals all said that they were going to Feixian City, she didn't object to it, so she went with the three immortals.

The Four Immortals stayed in the Leisurely Palace for a few days, and together with Duanmu Ziyu and the others, they received the token personally issued by Elder Jin of the Immortal Palace to participate in the Ten Thousand Immortals Conference on behalf of the Void Sun Immortal Palace. Ironically, it was none other than the Great Elder of the Heavenly Demon Sect who issued them tokens!

This Elder Jin dared to reveal his true identity in front of Li Muran and the others, just to tell Li Muran and the others that he had already taken all possible measures, and he was not afraid of Li Muran and the others to publicize this matter at all.

When issuing the token, Elder Jin also told Li Muran and the others a few words meaningfully, in the eyes of outsiders, it was just a few ordinary words of praise, but Li Muran and the others knew it well and could hear the meaning of coercion.

Elder Jin finally said: "Eight little friends, get ready, in a few months, this seat will personally escort you to the Ten Thousand Immortals Conference! Any team that enters the top eight will have additional rich rewards from the Immortal Palace!"

After receiving the token, Li Muran and the other four immortals left the Leisurely Palace and went to Feixian City.

In the Flying Immortal City, Li Muran saw many old people, and all the monks were amazed by Li Muran's advancement to the True Immortal, and congratulated them one after another. Li Muran also took the opportunity to inquire about Huoyun, Nirvana and others, but he didn't get the slightest clue.

Even Hua Ling, who had ascended to the Immortal Realm hundreds of years earlier, seemed to have completely disappeared, leaving no clues of his whereabouts in Flying Immortal City.

"It seems that Huoyun, Nirvana, and Hualing have never been to Flying Immortal City!" Li Muran sighed in his heart.

Li Muran once heard Tie Changkong mention that there was an insect cultivator elder of the Golden Immortal Cultivator in the Flying Immortal City, and he was very opposed to Tie Changkong's move to ask the Immortal Palace for help because of the insect plague in the Nether, because the immortals speculated that the person who controlled the clone of the Sword Immortal was also an Insect Cultivator of the Golden Immortal Cultivator, so he also secretly investigated in the Flying Immortal City by the way.

The result was quite disappointing, because this so-called insect cultivation elder only had the Taiyi Golden Immortal cultivation in the early stage of the Golden Immortal, and he had only advanced to the Golden Immortal in the last few thousand years. And the Easy Sword Immortal clone was controlled by the insect cultivator, at least it was something that had happened tens of thousands of years ago, so the suspicion of this insect cultivator elder was basically ruled out.

After cultivating to the true immortal, no matter what the origin is, it is an immortal body, unless it is oneself who reveals his true body, it is difficult to judge the origin of the monk from the appearance. And the Golden Immortal Elder will not easily reveal his origin, so it is very difficult to find out which Insect Cultivation Elder controlled the Easy Sword Immortal clone!

The Four Immortals had been stranded in Flying Immortal City for several months, and finally received a message one day: Elder Jin of the Immortal Palace ordered them to assemble in the Leisurely Palace, and they would leave the Void Sun Immortal Realm and participate in the Ten Thousand Immortals Conference in a few days!
