Duanmu Xiaotian, who was practicing under the Heavenly Wind Thunder Abyss Wind Thunder Heavenly Tree, completely recovered from his injuries and began a new cultivation. He took out a lock spirit box from the storage bag, opened the forbidden heaven talisman seal sealed on it, and opened it, and suddenly a thunderbolt emanated.

The Red Sky Thunder Immortal Stone and the Wind Thunder Fierce leaned over together, wanting to check the thunder things in the box.

"This is the thing that the Immortal Realm Heavenly Thunder Ancestor gave you, what is it that can make you pay so much attention to it. Chitian Thunder Immortal Stone asked.

Duanmu Xiaotian glanced up at the Red Sky Thunder Immortal Stone and the Wind Thunder Hideous, and reached into the lock spirit box with his right hand and took out the spiritual object inside. Like the tip of a sword, it's just a cracked stump, only a small piece.

"This is ......" Chitian Thunder Immortal Stone exclaimed, thinking of the origin of this thing, "It's the tip of the Xuantian Rune Sword. ”

"It should be ......" Duanmu Xiaotian nodded, "Anyway, with my senses, there shouldn't be anything wrong." This remnant of the sword, there are runes on it, and it looks like a thunder rune, and the other side is estimated to be the last character of the nine-character mantra rune. ”

"The last thunder rune. The Red Sky Thunder Immortal Stone jumped a few times, leaned over, and a thunderous power emanated, probing the fragments of the sword tip.

"Do seniors know what this last thunder rune is?"

"Hey...... I don't know, but the wind and thunder do. ”

"Wind and Thunder ......" Duanmu Xiaotian was full of surprise, looked at the wind and thunder, and saw that the wind and thunder nodded fiercely, and became more curious about the wind and thunder for a while.

"Why, what kind of eyes are you kid. There are not many brute beasts that can survive from ancient times to the present, and they have undergone two changes in heaven and earth without being destroyed, and all those who survive are the strongest among the brute beasts. Wind and Thunder are savage beasts that have lived since ancient times! Yu Bai's Five Elements Thunder Rune was obtained from the Wind Thunder Hideous, you kid don't know it!"

Duanmu Xiaotian opened his big mouth and looked at the wind and thunder, and was extremely shocked. Such an ancient secret, he really didn't know. It is estimated that there are few people in the whole world who know about it.

However, the wind and thunder shook his head, Duanmu Xiaotian didn't know what it meant, and immediately looked at the Chitian Thunder Immortal Stone.

"Forgot ...... You kid can't understand the words of the wind and thunder. It doesn't matter, with your current ability, you can understand, I'll teach you. As soon as he finished speaking, the Red Sky Thunder Immortal Stone exerted a thunderous power and injected it into Duanmu Xiaotian's Yuan Shen. The Red Sky Thunder Immortal Stone has been conceived by Duanmu Xiaotian for so many years, and the power can already be communicated, and soon Duanmu Xiaotian will get a way to communicate with the Wind Thunder.

Wind and thunder can only scream, and its voice will signal like a human speak. However, it takes the power of the Immortal Dao to obtain it in a special way, and Duanmu Xiaotian's current ability can exert the power of the Immortal Dao, so according to the method of the Red Sky Thunder Immortal Stone, he can finally understand.

According to what Wind and Thunder said, in the ancient period of the Five Elements Thunder Rune, some of the origin thunder was obtained, and it was born from the power of the Wind and Thunder Origin, and many forces have such a heritage. And Yu Bai also obtained some of the Five Elements Origin Thunder Dao to comprehend the Thunder Runes in it, and finally completely comprehended the Five Elements Thunder Runes here in the Wind Thunder Hide, of course, the power of the Five Elements Thunder of the Wind and Thunder Thunder was also raised by one level.

As for the remaining four Thunder Runes, they were the Yin Void Immortal Thunder Rune, the Yang Reality Immortal Thunder Rune, the Chaos Heavenly Thunder Rune, and the Open Heaven God Thunder Rune. The Yin Void Immortal Thunder Rune and the Yang Reality Immortal Thunder Rune do exist, and it is only from the more ancient Thunder Origin that the ancient forces of the Immortal Realm should have a broken rune inheritance in their hands.

Yu Bai was originally a disciple of an ancient force in the immortal world, and his sect was destroyed, and he was the only one who escaped, so there was the inheritance of these two runes. In order to complete the rune, Yu Bai relied on the strength of his own primordial god to defeat the immortal soul, and escaped into the chaotic void in the form of a primordial god, looking for the ancient origin of thunder, and it took tens of thousands of years to find and comprehend the true Yin Void Yang Immortal Thunder rune.

As for the two thunder runes in the back, they were also created by Yu Bai when he escaped into the immortal realm in the form of a primordial god, watching the opening of the Chaos Immortal Realm, and fused the previous six thunder runes to create by himself, and no other force has these two runes inherited.

Hearing this, Duanmu Xiaotian felt extremely shocked. It is estimated that no one knows anything except the wind and thunder. Listening to the introduction of Wind and Thunder, Duanmu Xiaotian knew a lot, but he also had a lot of doubts, doubts about the Heavenly Soul Forbidden Technique.

So Duanmu Xiaotian immediately inquired about the Heavenly Soul Forbidden Technique. However, Feng Lei responded that he didn't know much about it, after all, this technique was the foundation of Yu Bai's cultivation.

It's just that he knows that the Heavenly Soul Divine Technique was actually created by Yu Bai, but he has a lot of heavy identities and hides a lot of things. The power of this technique lies in the fact that the original spirit is in a state of immortality and immortality, which can be directly reborn, and can escape into the belly of a pregnant woman and be reincarnated. However, this reincarnation, which does not go through reincarnation, needs to be reincarnated into an unformed baby that is related to oneself by blood.

And the reincarnation of Duanmu Xiaotian is estimated to be related to the stone that Dao Xuanzong got from the deserted city, and that stone should contain Yu Bai's soul power in it. Although Yu Bai's primordial spirit is extinguished, his soul power will not dissipate. Although Duanmu Xiaotian did not practice the Heavenly Soul Divine Technique, Yu Bai's soul power in the stone was absorbed by Duanmu Xiaotian's Yuan Shen, so it made the Yuan Shen immortal, and the obsession was too deep, so he could be reincarnated and returned.

Yu Bai is the creator of the Heavenly Soul Divine Technique, he has practiced for an unknown number of years, and his Yuan Shen power is too powerful, and any bit of soul power can be immortalized or dissipated.

"Boy, maybe you don't know, in fact, the soul splitting and soul cultivation technique was also created by Yu Bai, and this technique was given to Wind Thunder Hideous, and I learned it from Wind Thunder Hideous. In my opinion, that Xuantian rune sword is estimated to be the result of Yu Bai's creation of the soul splitting and soul cultivation technique, although the spirituality has been extinguished, but Yu Bai's soul power is still retained on it. That's why you were in the middle of a deserted city before you could be recognized by it. You must know that so many years have passed, including so many immortals in the ancient period, who have not been able to bring this sword out of the deserted city, but you kid can, this must be related to soul power. In the soul land, Yu Bai's soul power was partially absorbed by you, and the other part was absorbed by the Xuantian Fu Sword, this is the evidence. ”

"I'll ...... is so powerful, Yu Bai's predecessors are really powerful. Duanmu Xiaotian was full of emotion, and sincerely had supreme admiration for Yu Bai.

"So, boy, you haven't cultivated the Heavenly Soul Divine Technique, although the Yuan Shen has reached the point of immortality, but it is still far from the real immortality? Yu Bai's Yuan Shen can't be wiped out with Dao Immortal-level immortal weapons. However, it also gives you the opportunity to advance to the Wonderland. ”
