Xu Yang smiled and said, "You don't have to thank me. First, your life is mine. If you want to work hard for me, I will help you through the Ghost Emperor's catastrophe, which means you have four Ghost Emperors and your power will increase greatly! Second, when helping you through the tribulation, I have gained some understanding of the way of the Thunder Extreme Rune, and I have also benefited a lot."

"Master, we have all been promoted to Ghost Emperor. When will you break through?" asked the Chili Ghost Emperor, "I think that even if I have already broken through to Ghost Emperor, I am still no match for the Master. With such strong accumulation, can't I complete the breakthrough?"

The Ebony Ghost Emperor said: "Once the master breaks through, his combat power will be far beyond that of ordinary emperors. Even the Invincible Xuan Emperor will not be his opponent."

Xu Yang shook his head and said, "I should have some time to go through the breakthrough. I just passed the tribulation, which deepened my understanding of the Thunder Rune Way. When I go back to seclusion, I will try whether I can break through the realm of Xuanwang."

"Then we four, I wish our master a success." Chili Ghost Emperor flattered.

In the next few days, the four new ghost emperors will use the powerful ghost energy in the ghost hill to enhance their resentment reserves and devour hundreds of ghosts every day. Only the ghost hill can have so many powerful ghosts for them to swallow. If it were other places, there would be no shadow of ghosts.

On this day, Xu Yang went into seclusion in front of the huge statue of the Tomb of Ten Thousand Ghosts as usual, and the four ghost emperors went out to hunt. But at noon, the Ghost Emperor Tijuan returned and handed Xu Yang a long sword, offering treasures: "Master, this long sword is a good treasure, I took it from a ghost..."

"Um..." Xu Yang didn't care much about the treasure now. He took the long sword and released a trace of spiritual power. He swept over the blade slightly.

"There is a 'Clime' mysterious formation engraved on it, which should be written by the Xuanhuang-level weapon refining master. However, there is still a fundamental difference from the growing treasure such as the Blood Drinking Sword. I am not good at using a knife, so I will give it to you."

When Xu Yang was about to throw the long sword treasure to Tijuan, his mind suddenly swept across the position of the hilt. His hand suddenly became stuck.

"Master, what's wrong?" said the Ghost Emperor Tijuan in surprise.

Xu Yang turned over the hilt of the knife and looked carefully. Sure enough, Xu Yang found a small word "blue" near the hilt of the knife!

"This knife... looks so familiar, is it..." Xu Yang's eyes flashed with surprise, "Tijuan, where did you grab this knife?"

The Ghost Emperor Tijuan said: "It is a ghost who has not yet been promoted to the Ghost King, and his mind is also confused. It seems that he has just become a ghost. It seems that he has just become a ghost..."

Xu Yang sighed, and his guess was confirmed. This knife was vaguely the same as the long sword used by Lan Jiansan, an inner disciple of the Emperor Sect! Then, Lan Jiansan should have encountered misfortune. It is very likely that the ghost that was swallowed by the cuckoo was transformed by Lan Jiansan after his death.

"I didn't expect that Senior Brother Lan, who was riding with me in the Shenzhou, died in this ghost hill..." Xu Yang sighed a little. The road to Xiuxuan was not smooth, but there were thorns on the ground, and he might die if he was accidentally.

"Master, can you say...you recognize the master of this long sword?" Tijuan Guihuang asked carefully.

"Yes, I just didn't expect him to become a ghost. It's better to be swallowed by you than to be confused and continue to harm the living." Xu Yang said.

The low-level Yin Ghost was in a daze and knew that he could only swallow living people and his kind. Only when he reached the level of the ghost coach would he develop his mind. But the Yin Ghost at this time was already another creature, completely different from before his death. Therefore, even if Xu Yang found the Yin Ghost formed after the death of Lan Jian San, he could not restore the consciousness of Lan Jian San, let alone restore it to humans.

"In this case, this knife cannot be given to you," Xu Yang said, "I want to bring it back to the sect to explain the news of Senior Brother Lan's death."

The Ghost Emperor of Tijuan smiled and said, "Don't worry, the master is good at using whips and will not use a knife."

"Where did you meet that ghost?" Xu Yang put away the treasure sword and asked, "I'll go find out if there is any bones of Senior Brother Lan, so that he can also collect it and take it back to the sect for burial."

The Ghost Emperor of Tingjuan nodded and flew all the way to the southwest with Xu Yang. Soon after, he came to a valley with yin energy. There were many white bone residues here, like a mass grave.

"I didn't expect there were so many corpses here. It would be difficult to find Senior Brother Lan's body now." Xu Yang sighed.

Tijuan beside him smiled and said, "Master, this may not be the case."

"Oh? Do you have a way to find it?" Xu Yang said.

"Just count the time. It only took three or four years for the master's fellow disciple to lose contact in Guiqiu. It is normal for the body to corrupt and disappear after three or four years, but it takes more than five years for the cartilage and tendons to truly disappear. The bones completely lose nutrients and become dry, at least ten years! After understanding this, it is actually very easy to find the bones that have died within a few years." said the Ghost Emperor Tijuan.

Xu Yang really opened his eyes. The so-called specialization in skills and honesty is true. He immediately pointed his eyebrows and a blue mental power swept out, gently brushing the bones.

However, after Xu Yang investigated, he did not find any human corpses that had died within five years. Most of these corpses were dry and fragile, and some even turned into ashes after a touch. It was obvious that they were skeletons that had died for countless years.

Xu Yang searched with his mental power three times, but he could not find any trace of Lan Jiansan's corpse.

"Strange, can it be said that the third senior brother of Lan Jian died in other areas of the Ghost Hill. The ghost turned into a ghost after his death wandered into this valley? So we can't find his corpse here." Xu Yang said.

"It should be impossible. A ghost without sanity, who only acts by instinct, rarely leaves his own land of death." The ghost emperor of Tijuan is naturally a great expert in understanding the ghost.

In the end, Xu Yang could only sigh and gave up his efforts: "Perhaps, Senior Brother Lan's auspicious person and heavenly appearance are not dead, and it is unknown."

Swish, swish, from the northeast, several mysterious lights flew towards Ye Dong, Bai Yining, Cai Li, and the other three ghost emperors.

"Master, after these days of cultivation, we have stabilized the realm of the Ghost Emperor. With our potential, even if we deal with the Peak Ghost Emperor, it is no problem." said the Ebony Ghost Emperor.
