"The so-called rebirth naturally means that after death, all people have to go to the underworld to accept the final judgment, or enter reincarnation, or go to purgatory, and no one can escape!" Xuan Yue explained.

"In other words, at this time, Su Yun's divine soul is already in the underworld, and she is about to be escorted to the Cui Mansion for trial, as long as I can bring her soul back, I will be able to regenerate her?" Xiao Yu asked as he stared at Xuan Yue with burning eyes.

"Yes, the journey to the underworld is too far, even if you don't eat or drink at full speed, it will take three months to reach the gate of the underworld, and on the way, you have to cross the Yellow Spring, cross the gate of life and death, step on the Nai He Bridge, see the Sansheng Stone, drink Meng Po soup, and finally have to walk barefoot through the purgatory danger before you can finally reach the Twilight City, which is where the Cui Mansion is located, so if you set off now, it is possible to intercept Su Yun's spirit in time for Black and White Impermanence to send Su Yun's spirit to the Cui Mansion and bring it back. If it's too late, when Su Yun's soul enters Cui's mansion, it will be difficult to save her again, everyone knows that Judge Cui is cold-faced and selfless, and the law is not merciful, and he will definitely not let you bring Su Yun's soul back" Xuan Yue snorted coldly.

"In that case, I'll go to the underworld immediately! Thank you!" Xiao Yu said thank you and left in a hurry. When he returned to the army, he temporarily handed over the northern army to Wei Xian under the command of Wei Xian, and asked him to lead the northern army back to the upper demon realm for the time being, and everything would be planned after he returned.

After informing Linglong of the summons, he gave an explanation to Nie Hong, Ye Rufeng and others, and asked them to fully assist Wei Xian in guarding the Demon Realm, and after explaining everything, he left in a hurry. Afraid that everyone would be worried, Xiao Yu didn't tell everyone where he went, but just said that he had something very urgent to do, and he would return in March or May as soon as possible, or a year or two at the latest.

The exit to the underworld, Xiao Yu knows that there are two, one is on the Immortal Island, and the other is in the forbidden land of the back mountain of the Fire Palace, the Immortal Island is on the Sea of No Immortals, it is too far from here, Xiao Yu decisively chose the forbidden land of the back mountain of the Fire Palace.

Xiao Yu has a deep hatred with the Fire Palace, and has killed a lot of people in the Fire Palace, and even the nephew Ding Yue and nephew Huo Lie of the Fire Palace Palace Lord Huo Yunfei were also killed by him, when the Fire Palace blessed the Demon Seven to cultivate the Demon Skill, he was also disturbed by Xiao Yu many times, and suffered heavy losses, with such a deep grudge, it stands to reason that it is impossible for the Fire Palace to let Xiao Yu enter his own forbidden land in the back mountain, but to Xiao Yu's surprise, when the disciple of the Fire Palace guarding the mountain gate reported Xiao Yu's intention to the palace master, the palace master Huo Yunfei actually agreed to Xiao Yu's request.

Huo Yunfei, the palace master of the Fire Palace, sent an inner disciple to lead Xiao Yu to the entrance of the Nine Hells in the back mountain, and then stopped, after all, not everyone dared to break into the Nine Hells, and the disciples of the Fire Palace who broke into the Nine Hells did not know how many, but none of them had a good end, just ask such a terrifying place, how could this inner disciple dare to accompany Xiao Yu to go on an adventure, anyway, the palace master only asked him to bring Xiao Yu to the entrance of the Nine Hells, and did not forcibly ask him to send Xiao Yu down, he naturally would not be stupid.

Xiao Yu thanked such a disciple of the Fire Palace, and went into the long and deep cave alone. After confirming that Xiao Yu had entered the Nine Hells, this disciple returned to the Qianshan Sect alone to report Xiao Yu's situation to the palace master Huo Yunfei.

After listening to this disciple's report, Huo Yunfei asked the elders around him, "What do you think this Xiao Yu wants to do when he enters the Nine Hells?"

"Is it going in treasure hunting?" someone replied.

"Treasure hunting? Just because he is a god transformation stage monk, he also wants to go into the Nine Hells to hunt for treasures, really think that Netherfire is an ornament?" someone next to him retorted.

"This Xiao Yu is strange, I heard that the senior of the Dixing Palace said that this Xiao Yu is a certain powerful descendant of ancient times, with a secret method, it can't be reasoned, maybe he is really not afraid of the Netherfire, not necessarily!" Huo Yunfei pondered.

"Then do you want to send someone to deal with him?" someone asked.

"Send two puppets from the Tribulation Period to follow him and see what the hell he does, but don't act rashly, even if you do it, you have to wait until you are absolutely sure before doing it," Huo Yunfei commanded.

"Yes, I'll arrange it."

Xiao Yu naturally didn't know that the Fire Palace was still undead towards him, and at this time, he had once again walked to the edge of the cliff against the huge yin wind. The bone-devouring cold almost froze his soul, but since his Myriad Phases Martial God Technique broke through to the Martial King Realm, the strength of his body had become so strong that he was able to carry the Suo Suo Yin Wind of the Nine Hells.

At the cliff, two vicious yaksha holding a triangular steel fork stared at Xiao Yu with angry eyes, staring at Xiao Yu viciously, as if they wanted to take the opportunity to swallow Xiao Yu.

On the cliff and stone wall, there are still eight ancient fonts, faintly flowing with the ancient atmosphere: "Yang Shou is over, and he will be reborn in the underworld!" Walking to the end of the cliff, I saw an endless sea of dark green fire, which was the dark sea of fire at the junction of yin and yang.

I still remember that when Xiao Yu first came here, the cold Nether Fire almost killed Xiao Yu, but now Xiao Yu can summon the Nether Fire himself, so he is naturally no longer afraid of the biting cold of the Nether Fire.

Xiao Yu's arms were stretched, and he jumped lightly, jumping down against the Netherfire Sea below, all the way unimpeded, and soon fell to the bottom of the Netherfire Sea, and the thick flowing Netherworld Magma continued to spew upwards with Netherworld flames that were hot on the outside and cold on the inside.

One of the nine dark green lotus flowers in the magma has withered, and the remaining eight are budding and ready to be released, and the treasure light flows, and it looks like it is about to bloom in the next few years. Xiao Yu knows that every flower of this fire lotus will give birth to a fire spirit, this time if the eight fire lotus bloom at the same time, eight fire spirits will be born, it seems that this fire lotus ancestor must be recovered as soon as possible, people are selfish, although Xiao Yu no longer needs the fire spirit, but he doesn't want the fire lotus to fall into the hands of others.

"Senior, senior!" Xiao Yu gathered his thoughts and shouted loudly at the rolling magma.

The rumbling magma bubbled upwards, and then surged violently, two antlers were revealed first, and then a huge bull's head emerged magma, the bull's head, the horse's mouth, the shrimp's eyes, the elephant's ears, the snake's neck, and the unicorn's torso, covered with scales, were the old dragon's head who was imprisoned here.

The old dragon's huge shrimp eyes stared at Xiao Yu, and asked loudly, "But have you found a way to untie the old man's shackles?" The voice rumbled and echoed over the Netherworld Fire Sea.

"Not yet!" Xiao Yu said ashamedly.

Hearing this, the old dragon head no longer paid attention to Xiao Yu, and lowered his head to prepare to drill into the netherworld magma again, Xiao Yu hurriedly stopped him, "Senior, slow, although I haven't found a way to untie the shackles of my predecessors yet, but I will find a way as soon as possible, I am going to go to the underworld this time, maybe I can find a way to influence the Fire Lotus Ancestor!"

"Are you going to the underworld?" When the old dragon head heard that Xiao Yu was going to the underworld, he immediately raised his head with a strange look and stared at Xiao Yu.

"Exactly! I wonder if the predecessors have any advice?" Xiao Yu knew that the road to the underworld must be dangerous and abnormal, if there was the guidance of the old dragon head, maybe he would avoid a lot of unnecessary troubles along the way, after all, the old dragon head has been squatting at the gate of the underworld for five million years, and he is quite familiar with the underworld.

"There is a Jiuhua Mountain in the northernmost part of the Purgatory of the Underworld, and there is a clan on the mountain called the Silla royal family, when you cross Jiuhua Mountain, you will meet a destined person, and he will help you read all the misfortunes" The old dragon's tone suddenly became mysterious.

"Jiuhua Mountain?Silla royal family?" Xiao Yu silently wrote down the words of the old dragon head, hurriedly bid farewell to the old dragon head, and plunged into the sea of netherworld fire.

The Netherfire Sponge stretches for 30,000 feet, Xiao Yu is now walking through it, without the slightest feeling of discomfort, along the way, Xiao Yu's ears seem to hear the continuous terrible screams in the sea of fire, all the living creatures in the Yang World will be burned by the Netherfire when they arrive here, and all the Yang breath will be cut off.

After passing through the sea of netherworld fire, there was a sudden silence all around, it was the kind of silence that was quieter than any quiet place in the world, no sound could be heard, even time and space were still, the only thing Xiao Yu could hear was the sigh of his soul.

A pitch-black meadow about three hundred zhang wide separated the Netherworld Fire Sea from a pitch-black gate, at first glance, the pitch-black gate was deep and charming, attracting Xiao Yu's eyeballs and attracting him to explore the secrets behind the door. When he looked at it again, Xiao Yu was startled by the situation on the door, and he didn't see a lot of hideous skulls looming on the originally dark door, crying or laughing or happy or sad at Xiao Yu.

Coming back to his senses and not daring to look at it again, Xiao Yu slowly stepped across the pitch-black grass three hundred zhang wide, and there were a lot of pitch-black grass-like plants growing on the ground, and there were occasionally beautiful rainbow-colored flowers between the pitch-black weeds, with flowers without leaves, and with leaves without flowers.

Xiao Yu looked at the grass-like plants and the small rainbow-colored flowers, and actually had a sense of déjà vu, trying to recall the ancient treasures recorded on the Danfang, and suddenly two strange names appeared in Xiao Yu's mind.

"Soul Rejuvenation Grass!"

"Soul Rejuvenation Grass, growing in the intersection of the two worlds of Yin and Yang, has the effect of resurrecting the dead, using the Soul Rejuvenation Grass as a medicine to refine the Nine Turns of Yang Pill, heal the dead, flesh and bones, is a rare miracle medicine in the world"

"The flowers on the other side, the flowers bloom for a thousand years, the flowers fall for a thousand years, the flowers and leaves are wrong, the world will never see each other, the flowers on the other side bloom on the other side, but there is nothing to do in front of the bridge! It is rumored that the flowers on the other side only bloom on both sides of the River Styx, with spirituality, but can never be incarnated into adults, the flowers on the other side are the main medicine for refining the elixir", Xiao Yu is no stranger to the elixir of longevity, when he was in the Xuandao Sect, the various sects were in order to compete for the immortal pill refined by the Zixiao Palace for the Xuandao Sect, and designed an ambush for the Xuandao Sect, and the Xuandao Sect went into decline!

Such a precious two-flavor immortal medicine can be seen everywhere here, if you collect all these immortal medicines, how many elixirs you have to refine, how much money you have to sell, when you think of this, Xiao Yu was so happy that she was about to faint, and it really felt that this trip was worth it.

Secretly looking around, as if he was afraid of being seen, he then pounced on the pitch-black ground at an incredible speed, frantically harvesting the resurrection grass and flowers on the ground.

The ground that was three hundred zhang wide was quickly swept by Xiao Yu. It should have been stored a lot, should it be used up before coming back?" Xiao Yu said guiltily. The divine sense probed into the chaotic space and took a look, and suddenly his eyes widened, revealing an expression full of incredulity.
