"Yes, I went out this time to find the Key to the Nine Shadows."

Yin Ming said with certainty that the relationship between the Key of the Nine Shadows is too great, and it has a great relationship with the Nine Shadows Secret Vault and the Yellow Spring Water, and only by getting the Key of the Nine Shadows can you open the Nine Shades Secret Vault and find out the Yellow Spring Water.

In that battle 100,000 years ago, the Hell Demon Sect was defeated, and the entire sect was killed countless times, and many treasures were lost, including the Nine Shades Key. For so many years, there was no trace of the Key of the Nine Shadows, and there were Nine Secret Treasures and Yellow Spring Water in the Yin and Dark Void, but they could not be opened, so they could only be hidden in the deepest depths.

This time, Yin Ming woke up from his slumber, and he naturally didn't want to miss this opportunity, so he wanted to find the Key of the Nine Shadows again, open the Nine Shadows Vault, take out the Yellow Spring Water, and recreate the supreme demon power of the Hell Demon Sect in the past.

It can be said that the Key of the Nine Shadows is related to the rise and fall of the Hell Demon Sect. If you find the Key of the Nine Shades, you will be able to obtain the Nine Shades Secret Treasure and Yellow Spring Water. Among them, the Nine Shadows Vault can recruit cultivators with low cultivation, and the Yellow Spring Water can recruit high-end cultivators, and together with each other, they can create a new Hell Demon Sect in the shortest possible time.

Of course, this kind of creation lacks a foundation, unlike other sects that have developed step by step, it is difficult to succeed, even if low-end cultivators and high-end cultivators are recruited, there is still a possibility of falling apart. However, even so, Yin Ming's heart still did not waver.

Moreover, even if it wasn't for the Hell Demon Sect, just for Lei Yu, Yin Shen would have to find the Key of the Nine Shadows, after all, the Nine Shadows Secret Vault and Yellow Spring Water were too important to Lei Yu. After getting the Nine Secret Treasures and Yellow Spring Water, Lei Yu didn't have to worry about the huge Lei Yuandan needed for promotion, and the same Yellow Spring Water could also wash his soul and help him reach a higher realm.

"When are you going to come back?"

Lei Yu asked again, it was imperative to find the key of the Nine Shadows, Lei Yu couldn't stop the will of the Yin Yin at all, so he could only start from the side. Although Yin Ming left, Lei Yu didn't believe that he would never come, so he asked.

"I don't know how long it will take to find the Key of the Nine Shades this time, but I can be sure that I won't be coming back until you reach the Thunder Infancy stage. ”

Yin Ming said affirmatively, without the slightest hesitation in his eyes, one of the agreements he had with Zixiao Ancestor was to ask Zixiao Ancestor to help restore his full strength.

And the key to this condition lies in Lei Yu, although Zixiao Ancestor is powerful, he can only be in a subordinate position in this matter.

If the Yin Thunder wants to restore its full strength, and the "Nine Nether Thunder Bell" wants to recover, only the Yin Nether Thunder Qi can do it, and it is also a large amount of Yin Nether Thunder Qi. And the "Yin Netherworld Demon Thunder" is not a mortal thunder, but a fairy thunder, if you want to get the Yin Netherworld Thunder, you can only communicate with the hell and the underworld, otherwise it is delusional.

Lei Yu cultivates the "Nine Shadows Yellow Spring Thunder", and is the best person to communicate with the Hell and Underworld. However, before the strength reaches the Thunder Infant Stage, it is very dangerous to communicate with the Hell Underworld, and if you are not careful, you may be wiped out by the Hell Underworld.

Moreover, to help Yin Ying recover his strength, he must go to the Hell Demon Pool, and it is extremely difficult to survive in the Hell Demon Pool without the strength of the Thunder Infancy, so Yin Ming will say that the Thunder Feather will not reach the Thunder Infancy Stage, and Jue will make up for it.

Only when Lei Yu's cultivation has reached the Thunder Infant Stage can it be possible to help Yin Yin. Before that, even if Lei Yu went to the Hell Demon Pool, he would only be sent to death, and besides, he didn't know what kind of place the Hell Demon Pool was.

"Senior, rest assured, I will definitely be able to reach the Thunder Infant Stage. ”

Lei Yu said affirmatively, with a firm look in his eyes, with his current cultivation and qualifications, if nothing happens, it is a sure thing to reach the Thunder Infant Stage, but if you want to really reach the Thunder Infant Stage, I am afraid it will take at least hundreds of years.

In other words, in these hundreds of years, Lei Yu was the only one who roamed out alone, facing all the problems alone.

"However, if my cultivation has reached the Thunder Infant Stage, how can I contact my seniors?"

Lei Yu asked another question, which was also very crucial.

After all, Yin Ying is a strong man in the Immortal Thunder Period, and he has gone without a trace, and for hundreds of years, it is impossible for Lei Yu to know where the Yin Yin of the Dao has gone, and it will be a troublesome thing to not be able to contact him at that time.

"Don't worry, I've thought about this a long time ago, this is one of my soul seeds, as long as I root this soul mark in your sea of consciousness, as long as you summon it at that time, no matter how far away I am, I will receive your news, you can rest assured." ”

The white light flashed in Yin Ming's hand, and a seed-like thing that shimmered with white light appeared in front of Lei Yu. It was the size of a thumb, covered in wonderful veins, and it was impossible to see what it was.

Suddenly, this seed spun around, and also turned into a white light that rushed into Lei Yu's eyebrows, and instantly entered his sea of consciousness. In a moment, Lei Yu felt a wonderful connection, as if there was a thread between him and the Yin Nether, no matter how far away he could be connected to the Yin Nether.

"Senior, this is much more useful than a telephonic note. ”

Lei Yu said with a smile.

"Of course, this soul seed is a part of my soul, it is closely related to my body, no matter how far away, I can feel the breath of this seed, you carry this seed, I can always know where you are. ”

Yin Ming said with a smile, the soul seed is also a part of the soul, which can cross time and geography and pass the news to me at the first time, which is a means that only the strong people in the Immortal Thunder Period can use, because in the Immortal Thunder Period, the soul is extremely condensed, and the soul can be divided to an extreme.

Below the Immortal Thunder Period, the soul of the cultivator is scattered, and the lack of a soul may cause great damage to the cultivator.

"By the way, I have one more thing for you!"

Yin Ming suddenly slapped his head, and his right hand stretched out, making a move into the distance, as if he was about to summon something.

"Boom!"

There was a roar, and a snow-white mountain peak in the distance surged in the direction of Lei Yu, as if it had wheels, extremely fast.

Lei Yu's divine thoughts dispersed, and when he saw the white giant mountain, he lost his mind for a while, because he had already seen what it was, it was the white bone giant mountain he saw when he strayed into the "Nine Nether Thunder Bell", but he didn't expect Yin Ying to give this thing to him.

The white bones are craggy, the white bone mountain is hundreds of zhang high, coming in the direction of Lei Yu, a gloomy aura erupts, as if there is an endless shadow of death floating in the air, although it has not yet come close, but Lei Yu's heart is already a little uncomfortable.

It is a mountain made entirely of bones, where millions of people have died. Even though Lei Yu had now become a cultivator, treating mortals as nothing, he still couldn't adapt to such a scene.

Yin Ming's right hand stretched out, his five fingers opened, and a piece of yellow light emerged, covering the White Bone Mountain. In an instant, the White Bone Mountain changed, and the huge peak shrank rapidly, turning into a small mountain only a few inches high after a while, which was taken into the hands of Yin Ying and became a doll.

"Boy, this is a thunder soldier that the Nine Shadows Emperor got from a demon cultivator, named White Bone Mountain, because it was too evil, so he threw it directly into my body, and wanted to use the endless Nine Shadows Yellow Spring Thunder Qi to refine the fierce qi in this thunder soldier, but unfortunately the deceased was too fast, even if there was more Nine Shadows Yellow Spring Thunder Qi, it couldn't be refined, so it has been placed in my body, I am about to leave, this White Bone Mountain will be given to you, as a thunder soldier for your life. ”

Yin Ming handed over this mountain of white bones to Lei Yu's hands, with a solemn face.

Lei Yu frowned slightly, the white bone mountain condensed by the white bones of millions of people made him feel a little uncomfortable in his heart, after all, he was once just a mortal, and seeing so many mortals being sacrificed into thunder soldiers, he felt a little resistant in his heart.

At this time, the white bone mountain is only a few inches in size, more condensed, and the white bones on it are more fine, and the original white bones cannot be seen at all, it looks like a delicate work of art, without the slightest gloomy color.

"Senior, let's change to a thunder soldier!"

Lei Yu said that he did not accept this mountain of bones.

"Boy, you think that I gave you the White Bone Mountain just for fun, right, this is a Dan soldier, I gave it to you because you don't have enough means to save your life. Although you have a lot of thunder soldiers now, there are not many thunder soldiers who can save your life, although the seal of the Nine Shadows is powerful, but it also consumes too much thunder power, with your current strength, I am afraid that you will become a human to use it once. ”

"This White Bone Mountain isn't outstanding among the Dan soldiers, but it's just right for you right now. Besides, it's not without purpose for me to send it to you, this White Bone Mountain has gathered too many people's grievances, and it has been difficult to eliminate, if you can keep this White Bone Mountain by your side, you can use the Nine Shadows Yellow Spring Thunder Qi to condense the White Bone Mountain, make it reborn, and strengthen the White Bone Mountain, and at the same time, it can also allow these unjust souls to be reincarnated and eliminate the resentment in their hearts. ”

Yin Ming told his hard work, making Lei Yu nod involuntarily.

According to Yin Ming, the White Bone Mountain is the best for him. This is a low-grade Dan soldier, although he is a cultivator in the Lei Gang period, he can also urge it, and the thunder power consumed is not much, which is just right for him to use.

If you encounter a critical situation, it is the best fatal magic weapon to directly smash down a mountain of white bones to ensure that the enemy is crushed to death.

Moreover, using the Nine Shadows Yellow Spring Thunder Qi to purify the grievances of the dead souls can also improve the purity of the Nine Shadows Yellow Spring Thunder Qi, which can be described as killing two birds with one stone.

"Okay, in that case, then I'll take it. ”

Lei Yu said, reaching out to take the several inches high White Bone Mountain. From now on, this is his Dan soldier.
