"Boom!" In the sky, the gate of the Hell Netherworld was slowly closing, and the inheritance in it was getting less and less, but Lei Yu had already mastered the Nine Shadows Yellow Spring Thunder at this moment, and he didn't pay the slightest attention to the closure of the Hell Netherworld.

His body is full of thunder, and it has reached a point where it is boiling and overflowing, and his whole body is inexhaustible. The Nine Shadows Yellow Spring Thunder is too domineering, much stronger than the previous Lethe Thunder, and the two are not the same level at all.

After the Nine Shadows Yellow Spring Thunder replaced the Thunder of Lethe, Lei Yu's Heavenly ** Aperture has also undergone some changes, Aoki Thunder has been squeezed into a corner, except for the seeds of Chaos True Thunder, most of the positions of the Heavenly ** Aperture are occupied by the Nine Shadows Yellow Spring Thunder, which can be described as the real protagonist.

"Nine Shadows Yellow Spring Thunder, give me a breakthrough to the ninth order of thunder qi and enter the tenth order of thunder qi!"

Lei Yu urged the Nine Shadows Yellow Spring Thunder in his body to make another breakthrough. After obtaining the inheritance of the Nine Shadows Yellow Spring Thunder, his thunder power increased at an unimaginable rate, reaching an extreme, and it was time to hit the tenth order of thunder qi.

The tenth order of thunder qi, the last small realm of the thunder qi period, is much more difficult than the other nine small realms. After all, this is the last step of the Thunder Gang Period, the thunder power will gradually become stronger, showing a different scene, the power is multiplied, and it is not a little bit stronger than the ninth order of thunder qi, which cannot be underestimated.

For the small realm of the tenth order of thunder qi, Lei Yu attaches great importance to it, mobilizing the thunder power of the whole body to impact the tenth ** knot, and bursts of roars come out of Lei Yu's body, making a huge sound, and working hard to impact the tenth order of thunder qi.

Half an hour later, there was a loud "boom" in Lei Yu's body, as if there was a burst of thunder, and the tenth ** aperture was broken through, and the thunder finally reached the tenth level of thunder.

This process was much easier than Lei Yu imagined, after all, the Nine Shadows Yellow Spring Thunder was too domineering, no matter how strong the tenth ** trick was, under such a violent impact, it was instantly broken and rushed into the tenth order of thunder qi.

"My thunder power is starting to show signs of deterioration, and it is more refined. Lei Yu nodded, breaking into the tenth order of thunder qi, he also felt some changes, the most significant of which was that his own thunder power began to melt and became more pure.

If Lei Yu's thunder power was water before, now his thunder power can be described as ice. Turning water into ice, a cent of thunder power can be used for a few points, his strength is at least several times that of the previous one, and the end is extremely amazing.

"It seems to be the tenth day, I didn't expect that it only took me such a short time to complete the inheritance, and now it's time for Yin Ying to pick me up. Lei Yu muttered to himself, except for some troubles before, there was no problem with the rest of the inheritance, and it was extremely smooth, allowing him to easily achieve the purpose of the inheritance.

"Boy, sure enough, I didn't misread you, now you can go down the mountain, the old man has built a domain gate on that island, you don't need a thunder source stone, you just need to stand on it and teleport back, I'm waiting for you here." ”

An old voice came, very far away, but Lei Yu's face showed a smile, Yin Ming's consideration was indeed very detailed, and he built a domain gate to let him leave the island.

"Leave now, there's nothing left to linger here. ”

Lei Yu glanced at the Nine Shadows Altar, there was no change in the slightest, there was still a huge altar, and the long blood trough, everything had not changed, as if nothing had happened, but Lei Yu understood that he would never forget it.

After a stick of incense, Lei Yu went down the mountain and entered a small domain gate, and then he only felt a burst of white light flashing, his body quickly actinized, and the sound of "brush" disappeared, and when he woke up again, he appeared on the island where the underworld was located, full of greenery, and it was particularly conspicuous in this sea of nine shades.

"Senpai, I'm back. Lei Yu was happy in his heart, and he was not as cautious about Yin and Yin as before. Although this old man is using him, he is indeed improving his strength, there is no doubt about it. And there is no unhappiness between the two, and it is not surprising that there is such a performance.

"In ten days, you'll be back, which is a bit of a surprise. ”

Yin Ming looked at Lei Yu, and his face was also happy, and said: "Yes, you have mastered the Nine Shades Yellow Spring Thunder, and now your body has been infused with the Nine Shades Yellow Spring Thunder, the physique of the Nine Shades Body can be exerted to the limit, and with your current cultivation, you can definitely compete with the cultivators of the first to second orders of the Thunder Gang Stage." ”

"It won't be like this!" Lei Yu opened his mouth wide, although he had already estimated himself to be very powerful, but Yin Ming's words gave him a deeper understanding.

Being able to compete with the powerhouses of the Lei Gang Period, this was unimaginable for Lei Yu before, but since it was said from the mouth of the Yin Nether, Lei Yu had reason to believe that after all, the Yin Yin was the instrument spirit of the Nine Nether Thunder Bells, and he had seen much more things than his little cultivator.

"The old man knows that you don't believe it much, but now there is a chance for you to verify your strength, it depends on whether you dare to apply. Yin Ming said with a smile.

"Oh, I don't know what the opportunity is that the senior of the Dao Dao said. Lei Yu looked interested.

He has now reached the tenth level of thunder qi, his confidence has soared, and now that he has an opportunity that can give him a deeper understanding of his strength, he will naturally not refuse.

"Okay, old man, I'll take you there. Yin Ming smiled slightly, rolled up a gust of black wind, carried Thunder Feather into the air, and flew to the shore.

A moment later, Lei Yu came to the shore, which was flat, and in front of him was the raging Sea of Nine Shadows, which was extremely immense.

At this time, Lei Yu was a little puzzled, looking around, but he didn't find the slightest trace, and he didn't know what Lu Dao Yin was doing.

"You'll know the Tao later, I'll hide it first, and the rest will be up to you. If you can kill it, the old man will let you leave the Nine Nether Thunder Bells. ”

Yin Ming's figure became fainter and fainter, disappearing, and he didn't know where Lu Dao went, but Lei Yu knew that Yin Yin was not far from him, but he couldn't find it.

"Senior, you are not allowed to cheat on what you have said. ”

Lei Yu's eyes lit up, he also thought about leaving the Nine Nether Thunder Bell, but Yin Ying never said it accurately, now that he has this promise, he naturally has to cherish it, and he has some expectations for the next strong enemy.

"Naturally. Such a voice came from the air, and then disappeared, but Lei Yu understood that it was Yin Ming who agreed to him.

Lei Yu smiled slightly, walked on the shore, looked at the Sea of Nine Shadows, and felt a little intimacy. With the Nine Shadows Yellow Spring Thunder, he has a close connection with the Nine Shadows Sea, and can even mobilize the Nine Shadows Sea for his own use.

It can be said that as long as he is in the vicinity of the Nine Shadows Sea, his combat power will increase geometrically, which is immeasurable. Yin sent him to the shore of the Nine Shadows Sea, not to ask him to borrow the strength of the Nine Shadows Sea to fight against powerful enemies.

"It's here!" Lei Yu whispered to himself, now that he had reached the tenth level of thunder qi, his divine thoughts had also expanded a lot, and he could detect it within a radius of one mile.

At this moment, in his divine thoughts, a three-headed yaksha was flying rapidly, it was the one that Lei Yu had seen before, obviously, he also discovered the existence of Lei Yu, and the speed of his flight increased a lot, and he quickly caught up.

"Boy, I'll see where you go this time. The three-headed yaksha flew in front of Lei Yu, high up, with an arrogant face.

"Hmph, I want to see what you can do to subdue me?" Lei Yu snorted coldly, unceremonious to this three-headed Yaksha.

"You kid is very arrogant, I wonder if you will cry and beg me next?"

The three-headed Yaksha's cyan skin trembled, obviously angry, but his cultivation was much stronger than Lei Yu, and he didn't care, he was high and aggressive.

"Give you a chance, as long as you tell me about the secret treasures of the Hell Demon Sect, I can spare your life. Well, this condition should be good. The three-headed Yaksha spoke.

"Hell Demon Sect Secret Treasure?" Lei Yu was stunned, he didn't expect the other party to think that the Hell Demon Sect's secret treasure was hidden on his body. What kind of logic is this, he can't figure it out for a while.

"I've heard of the Hell Demon Sect's Vault, but I don't know exactly where it is. ”

Lei Yu smiled and shook his head, the secret treasure of the Hell Demon Sect is in these Nine Nether Thunder Bells, but it is estimated that these three Yaksha will not believe it if they say it. Besides, the Nine Nether Thunder Bells were so vast, and he didn't know exactly where the Hell Demon Sect's secret cache was hiding.

"Boy, don't be embarrassed, say it now, I can spare your life, otherwise you will suffer. The three-headed yaksha shouted, but Lei Yu saw that he was a little absent-minded, and looked behind him, a little strange.

"I'm afraid you have other Yin Soul Evil Creatures!"

Lei Yu said, this is his guess, when he entered the nine-story palace that day, not only the three-headed yaksha, but also the same demon was also present, I am afraid that they came to the nine nether thunder bells together.

"Hmph, give you a chance, or die!"

The three-headed Yaksha was annoyed, and a black trident appeared in his hand, aiming at Thunder Feather. As soon as there is a disagreement, he will do it immediately.

Lei Yu was enraged by the words of the three-headed yaksha, and his face appeared angry, and he said in a deep voice: "If you want to fight, you will fight, just let the horse come!"

He raised the thunder power of his whole body to an extreme, and the thunder of the Nine Shadows Yellow Spring was used by him, and the momentum of the tenth order of thunder qi suddenly emerged, and the battle intent boiled, and he faced the three-headed yaksha without flinching at all.

"Thunder Qi Tenth Order. The three-headed Yaksha's eyes shrank, revealing a surprised expression: "I didn't expect your cultivation to improve so quickly after entering the Nine Nether Thunder Bells. But let it all end there, I'm going to make you the ghost of my Nightsha, enslaved by me for the rest of your life. ”

Above the right hand of the three-headed yaksha, the black trident flashed with black light, surrounded by the yin qi of the forest, and there was a momentum condensing, ready to attack the thunder feather at any time.

"Let the horse come over and let me see what the hell is wrong with Lei Gangqi. Lei Yu was fearless, and the momentum of his whole body was also raised to the extreme, corresponding positively, without flinching at all.
