This sheepskin scroll records the details of the nine-story palace in detail, and it is not insignificant for Lei Yu. His heart was full of excitement, according to the parchment scroll, the domain gate was on the ninth floor of the palace, and it was the center of the Hell Demon Sect.

"Now I'm going to move on, I don't need to look for it layer by layer, but it's a lot less troublesome. Lei Yu carefully checked the parchment scroll and made sure that there was nothing wrong, so he continued on his way.

Compared with his previous caution, Lei Yu's speed this time was much faster, and he soon came to the third layer of the palace. According to this parchment scroll, there were also several dangerous places in the third-layer palace, but Lei Yu only took a cursory look at them, and did not go to those dangerous places, and soon, he also left the third-layer palace and headed towards the fourth-layer palace.

"The Yin Thunder Qi here is too strong, it can already suppress my qi and blood, and it takes a lot of strength to take every step, if it continues like this, I'm afraid it will be difficult for me to reach the ninth-layer palace. "Lei Yu has arrived at the fourth layer of the palace at this moment. He felt that the yin and thunder qi around him had reached a limit, and it was even a little difficult to breathe, which made Lei Yu very uncomfortable.

"No, I must reach the ninth layer of the palace, otherwise, I will most likely be trapped here. That domain gate is the only way out for me now, and I must not give up. Lei Yu muttered to himself in his heart, with a hint of perseverance in his eyes.

He stood up, and after a period of rest, Lei Yu continued to move forward, heading towards the fifth-layer palace. The nine-story palace is a hundred zhang high, and the yin and thunder aura of each layer of the palace is different, but compared to the previous floors, the back floors are more intense, almost reaching a thick level, making people a little unable to breathe air.

"This fifth-story palace is even more dilapidated, even worse than the previous four-story palace. Lei Yu stood on top of the fifth-floor palace, looking at the dilapidated palaces around him, with some emotion.

These nine-story palaces are more and more dilapidated layer by layer, but layer by layer is stronger than layer by layer of thunder and thunder. When he reached the fifth layer, Lei Yu felt that his body had begun to be squeezed by the Yin Thunder Qi, and streams of Yin Thunder Qi poured into Lei Yu's body like a madness, wanting to erode Lei Yu's body.

This was a terrifying scene, Lei Yu was frightened, and his whole body qi and blood were mobilized, forming a golden barrier outside his body, resisting these Yin and Thunder Qi outside his body.

"No, if this continues, sooner or later I will be eroded by these thunderous qi. You have to take a break and think about it in the long run. Lei Yu rested in the fifth-layer palace for a while, hoping to find a way to resist the Yin Thunder Qi, but after looking for a while in his space bag, Lei Yu found nothing, just took out the Lei Yuan Sword, hoping to have some effect.

The golden light of the Lei Yuan Sword is dazzling, and there is a strong thunder power contained in it. With this appearance, the surrounding yin and thunder qi was afraid to avoid it, and retreated, Lei Yu had a place to live, and he could rest for a while.

"Let's go, I'm going to see what the rest of the palace looks like. After Lei Yu finished resting, his heart was full of pride. With the help of Lei Yuanjian, at least Lei Yu would not feel so uncomfortable and could move on.

Ascend the spiral staircase all the way to the sixth floor of the palace. To Lei Yu's surprise, this sixth-layer palace did not have so much yin and thunder qi, but there was an eerie feeling surrounding Lei Yu's body, which was a little terrifying, as if it was being targeted by some yin soul and evil thing.

"What the hell happened here before, there was such a strong eerie atmosphere. Lei Yu was frightened, this layer was even more gloomy than the scene Lei Yu had seen on the second layer. Lei Yu only felt a chill rise from the bottom of his heart, making him shiver involuntarily.

"It seems to be an evil thing, wandering around this sixth-story palace. A white phantom flashed in Lei Yu's eyes, wearing a white robe, his face was covered by a layer of white light, he had no feet, and he was floating in the air, which was very terrifying.

Lei Yu immediately knew that this was an evil thing, and it seemed to be accompanied by this sixth-layer palace. This gloomy aura may have emanated from these evil things, covering the entire sixth-layer palace, so Lei Yu felt that frightening coldness.

"Hurry up and leave, if I am targeted by the evil creatures of this sixth-layer palace, I'm afraid I really won't be able to leave. Lei Yu made a decision to leave immediately while these Yin Soul Evil Things had not yet been discovered.

Walking up the spiral staircase, Lei Yu reached the seventh layer of the palace as fast as he could. A wave of yin and thunder qi oppressed, almost causing Lei Yu, who had just ascended to the seventh-layer palace, to lie down. Fortunately, the Lei Yuan Sword in his hand played a role, resisting this breath, so he didn't fall.

"The Yin Thunder Qi here is even more refined, ten times as much as the previous fifth-layer palace, even if an ordinary Thunder Gang Period powerhouse comes here, I'm afraid it won't be able to resist the suppression of the Yin Thunder Qi here. "Lei Yu had some heart palpitations, the Yin Thunder Qi here was too strong, and it was even more serious for a cultivator like him who cultivated Yang Thunder, and he was almost crushed.

Lei Yu only felt that his steps were extremely heavy, and there was a constant "squeaking" sound in his body, which was that his body could not withstand the oppression of the Yin Thunder Qi and began to be damaged. His body began to bleed, and in an instant, his body was covered in a layer of blood red, which was very terrifying.

"Ahem!" Lei Yu coughed, opened his mouth and spewed out a mouthful of blood, spraying to the ground, and soon this blood was dissolved and absorbed by these Yin Thunder Qi, which made Lei Yu even more frightened, these Yin Thunder Qi can also absorb flesh and blood and enhance his strength.

"I can't stay here any longer, or my body won't be able to take it. Lei Yu was a little flustered in his heart. In this short period of time, several bones in his body have been broken, and the pain is very great, making him a little unable to stand and about to fall.

With heavy steps, he began to walk towards the spiral staircase of the fifth-story palace. Coughing up blood step by step, leaving a long trail of blood on the ground, but it was quickly absorbed by these Yin Thunder Qi, adding a trace of bloody Qi.

Half an hour later, Lei Yu came to the spiral staircase of the seventh-floor palace. At this time, his face was bloodless, and the clothes on his body had been stained with blood. There was a constant stream of blood left behind, as if it was about to drain all of his blood.

He held the Thunder Source Sword in his hand, resisting the Yin Thunder Qi that was constantly surging up around him, isolating it. However, under the siege of such a thick Yin and Thunder Qi, it seemed that the Thunder Source Sword was also a little unable to resist, and the golden light dimmed a little.

"Poof!" Lei Yu spurted out a mouthful of blood and came to the spiral staircase of the seventh-floor palace. As long as he crossed this spiral staircase, he could leave the seventh floor of the palace. This layer was too difficult for a fourth-order cultivator like him, and it was only because of his physical strength that he was not crushed by the seventh-layer palace.

"I don't know what the eighth layer palace is?" Lei Yu smiled bitterly in his heart, the seventh layer palace is like this, what about the eighth layer? He has no confidence in his heart, but now he has no way back, he can only continue to move forward.

Removing the worries in his heart, Lei Yu continued to the eighth layer of the palace. At this moment, he could only leave here if he continued to advance and reach the ninth-floor palace and enter the domain gate. Other than that, he had no other choice.

Lei Yu's march was difficult with every step, his steps were heavy, his mind was drowsy, his mind was depressed, and he could fall down at any time. It was only with the support of a strong perseverance that Lei Yu was able to move forward. He was already in a state of drowsy, and he didn't know what Lu Dao was doing, but the perseverance in his heart was supporting him.

"Boom!" As if he had been hit hard, as soon as Lei Yu entered the eighth-layer palace, a huge force surged, hitting his body, making him can't help but fly into the distance. Lei Yu couldn't support it anymore, and was crushed by this thunderous aura.

The eighth-layer palace is still dilapidated, but the yin and thunder qi contained in it is even stronger, and it was hit hard as soon as it entered, which is not heavy.

"No, I must enter the ninth layer of the palace. A desire to survive occupied Lei Yu's mind, even if he was lying on the ground, his whole body ached, as if it was broken, he still wanted to move forward, and he did not change his original intention at all.

At this moment, the Thunder Source Sword, which had been flashing with golden light, suddenly extinguished. Unable to withstand such heavy pressure, it automatically extinguishes the spiritual light and saves its body. This extinguished, Lei Yu's body faced those thick yin and thunder qi, and the "creaking" sound continued to sound, and the bones in his body began to break everywhere.

No matter how Lei Yu tried to repair it, the Yin Thunder Qi was still destroying his body, and it was useless. Even though the body of the Nine Shadows was extremely strong, under the attack of so many Yin Thunder Qi, Lei Yu once again tried the feeling of death.

His face was full of struggle, trying to get out of this state, but his body did not allow it, the qi and blood in his body had been exhausted, and he had no strength, so he could only lie on the ground and let these yin and thunder qi destroy his body.

In the blink of an eye, Lei Yu's body was riddled with holes, dying, and about to die.

"Boom!" A bone-chilling cold gushed out from the depths of Lei Yu's body, spreading within Lei Yu's body, and began to expel the Yin Thunder Qi that had entered Lei Yu's body. That force actually appeared again, pouring into Lei Yu's body, saving Lei Yu's life.

With the addition of this mysterious power, Lei Yu's body improved rapidly, and the qi and blood in his whole body were constantly recovering. He woke up and felt a change in his body, and the mysterious power reappeared, which surprised him a little.

But soon, Lei Yu made a decision, taking this opportunity, he rushed all the way to enter the ninth-layer palace as soon as possible.
