The events of 3,000 years ago finally have some context.

But when Lu Xuan asked carefully, he couldn't ask anything, Chengyun Ancestor's memory back then was very vague, and he only had a little impression of the twelve-story building and the earth-shattering sword.

However, Lu Xuan had a more concerned question, and that was the mark on Chengyun Ancestor's forehead.

It is a matter of the Ancestor of Wuyazi, and it is a top matter for every disciple of the Spirit Cloud Sect.

When he asked Chengyun Ancestor, Chengyun touched the mark on his head and smiled: "This matter is simple, a thousand years ago, when the blood demon appeared in the abyss again, we demon clans thought that the past would repeat itself, and we were all shocked and inexplicable. So I went deep into the abyss with a few old companions to find out, but there were many blood demons at the time, and we were quickly dispersed. After I was left alone, I stumbled into the formation of suppressing the blood demon. ”

"At that time, I met your Lingyun Sect's Wuyazi. ”

"In short, I was rescued by Wu Yazi, and he personally sent me out of the depths of the abyss. I didn't have time to say thanks, so he went back to suppress the blood demon. ”

"I was grateful to him for saving his life, so I renamed our cave house Chengyun Cave and had the people of the clan engrave the mark on his sleeve on his forehead, so as to remember the saving grace forever. ”

At this point, Lu Xuan knew what had happened.

"Can the Ancestor find the formation that sealed the blood demon again?" Lu Xuan asked.

Chengyun Ancestor nodded, "Naturally, but what are your plans next?"

Lu Xuan didn't rush to answer, but started from Li Wuxin's experience, then to the human monk's counterattack, and then to his own experience of going to Tushan Kingdom, and only after everything was said did he say in a deep voice: "The blood demon is becoming more and more fierce every time, if you don't cut the grass and eradicate the roots this time, there will be endless disasters." So I wanted to go deep into the abyss and see if Leng Yuezhu could help. ”

"I see. ”

Chengyun Ancestor sighed and said, "That unintentional but we demon clans have been miserable." But he also did it unintentionally, so he didn't need to care. Now that this matter has come to this point, I think you can try your ideas. It's just that this time the Blood Demon Scourge is far more violent than the previous four times, and I'm afraid that we people alone won't be able to help. ”

"What does the Ancestor suggest?"

"Since the human monks have made a desperate bet, we can't sit idly by and wait for the demons in the Valley of Ten Thousand Demons, and after I recover my cultivation a little, I will go and gather the other demon clans, we might as well come and join forces. ”

"It's so natural. ”

Lu Xuan's heart was full of joy, with the demon emperor of Chengyun Ancestor, coming forward, the demons in the Ten Thousand Demon Valley would gather some of them, which was an unexpected joy.

"But ......"

Chengyun Ancestor changed his words, "There is one of the most powerful demon clans in this Ten Thousand Demon Valley, and it is not so easy to move them, unless you can pay some price. ”

Lu Xuan said solemnly: "It is about the ancestor of Wuyazi, as well as the lives of countless human monks, and the younger generation will do whatever it takes. ”

Chengyun Old Ancestor nodded, pointed to the three-story small building and said, "That vein demon clan has the other nine floors of the twelve-story building in their hands, if you are willing to hand over these three-story small buildings to them, I think they will definitely not refuse." ”

"No problem. ”

Lu Xuan nodded without hesitation.

He has never been a person who cherishes himself, although this three-story small building is extremely beneficial to his cultivation, but if he can get strong reinforcements to suppress the blood demon, Lu Xuan feels that it is very worthwhile. What's more, he doesn't feel that his cultivation is inseparable from these three-story small buildings, and as his horizons broaden day by day, he will definitely be able to find a better place for his cultivation.

The only pity is that he doesn't have the ability to study the Dao Pattern in this three-story small building, but the Dao Pattern is the ultimate existence in the spell, and Lu Xuan can't even dabble in the Cloud Talisman now, let alone covet the Dao Pattern.

Chengyun Ancestor was a little stunned.

He said so much before, in fact, he just wanted Lu Xuan to know how powerful his three-story building was. I want to nourish countless monks in the twelve-story building back then, who doesn't want to take it for himself, but Lu Xuan didn't hesitate to give up the three-story small building, this freedom is even Chengyun Ancestor is ashamed of himself.

"Good. Chengyun Ancestor exclaimed: "If you can suppress the blood demon this time, you will have the greatest credit. All the demon clans of the Ten Thousand Demon Valley will remember your benefits, and I don't need to mention it, from now on, if you have anything, Chengyun Cave will never give up. ”

"Old Ancestor is too worried. Lu Xuan smiled and said, "I'm also thinking about the sect." ”

The two chatted briefly about their next plans, and finally Lu Xuan asked how Chengyun Ancestor would be taken away by the blood demon. You must know that Chengyun Ancestor is a demon emperor, and it stands to reason that he shouldn't be taken away so easily. And Chengyun Ancestor did not shy away from it, and directly explained the experience.

It turned out that Chengyun Ancestor's cultivation had reached the peak of the tenth grade, and it would usher in the Heavenly Tribulation a few months ago.

Demons, like humans, will experience the three major tribulations when they cultivate to the realm of refining the Void and Merge Dao. Chengyun Ancestor was about to experience the first heavenly tribulation in his life, and naturally he was facing a great enemy. However, when the Heavenly Tribulation came, the blood demon actually took advantage of the void to enter, causing Chengyun Ancestor to fall short.

was seriously injured by the Heavenly Tribulation, and was taken away by the Blood Demon, if it wasn't for Lu Xuan appearing in the sky, Chengyun Ancestor would be finished.

"That ancestor's current cultivation is ......"

"It doesn't matter, although the tribulation failed, it won't take a few days to recover in this twelve-story building, even if it's not as good as a few months ago, but if the blood demon comes again, I'm not afraid of him. "Chengyun Ancestor is full of pride.

Lu Xuan was relieved, "Then don't disturb the ancestor's cultivation, and when the ancestor recovers, we will leave immediately." ”

With that, he got up and said goodbye.

............

Three days later.

Chengyun Ancestor took Lu Xuan and Huang Zheng and landed on top of a big river.

The river is surging, but it is red with blood.

There was a group of big blue and black fish in the river who were fighting with the blood demon, setting off a blood wave dozens of feet high.

Although this scene cannot be compared with Chengyun Cave, it is also extremely tragic, and the group of blue and black fish demons have obviously fallen behind. If it weren't for the fact that there was a big fish demon more than 20 zhang long who struggled to resist, I am afraid that this group of demons would have been wiped out long ago.

When Chengyun Ancestor saw the blood demon, his eyes were extremely red.

Roar!

With an earth-shattering roar, Chengyun Ancestor suddenly fell into the river, and his true body appeared in mid-air.

Hornless one-legged, gray giant.

Rumble!

The blood waves soared into the sky, and the river evaporated in mid-air, and at least half of the blood demons also turned into ashes. The remaining blood demons saw that the situation was not good and wanted to escape, but they saw that the sunlight was born on the top of Chengyun Ancestor's head, and the moonlight was born under his feet, turning into clouds and suddenly covering a radius of dozens of miles.

In the blink of an eye, the blood demon was gone.

Lu Xuan couldn't help but be speechless, he was worthy of being a ten-rank demon emperor, and he really wanted to start a fire that even the heavens and the earth were trembling.

Those big blue and black fish survived, and the fish demon led by him conjured up a bald black-clothed strong man, leading the clansmen behind him to call the ancestors, looking respectful and grateful.

Chengyun Ancestor came to gather his subordinates, and briefly explained what had happened, and the fish demon nodded in agreement without saying a word.

Lu Xuan couldn't help but be a little surprised.

Although the fish demon was embarrassed just now, his cultivation was at least a seven-rank demon king, and he knew that the depths of the abyss were a place of death, so he agreed so simply?

Huang Zheng looked at Lu Xuan's expression and said with a smile: "With Chengyun Ancestor coming forward, it is estimated that the vast majority of the demon clan will not refuse." ”

"Why, is it because the Ancestor is the Demon Emperor?"

"This is one of them, can't you see the origin of Chengyun Ancestor?"

Lu Xuan shook his head, he really didn't know anything about the demon clan.

Huang Zheng smiled and said, "Then have you heard of Kui Niu?"

Lu Xuan was startled when he heard this, and then suddenly realized.

Although he didn't know much about the demon clan, he had heard of the name of Kui Niu. Human monks have a bloodline, and there are many types of demon clans, and they pay more attention to bloodline. Just like the nine-tailed demon fox of the Tu Shan clan, it is the noble bloodline of the demon clan, and it is naturally powerful. And even if Kui Niu is not as good as the nine-tailed demon fox, it is similar, the legendary Kui Niu has no horns and one leg, accompanied by the sun and moon on his body, roaring thunderously, swallowing mountains and rivers.

It turns out that Chengyun Ancestor is Kui Niu!

Although Lu Xuan had seen Chengyun Ancestor's true body, he really didn't expect this.

No wonder the fish demon will obey unconditionally, after all, Chengyun Ancestor is not only a profound cultivator, but also has a natural prestige among the demon clan.

At this time, Chengyun Ancestor brought the Fish Demon Clan to see Lu Xuan, and after some introduction, Lu Xuan sent the Fish Demon Clan into the Xiyang furnace without mentioning it.

......

Next, Chengyun Ancestor took Lu Xuan and Huang Zheng to a few places.

There are blood demons raging almost everywhere, but with Chengyun Ancestor, there is no need for Lu Xuan and Huang Zheng at all, and the blood demons will be wiped out in a snap of his fingers, Lu Xuan only needs to continue to send all kinds of demon clans into the furnace.

Then Chengyun Ancestor came to a ruined wall again.

Lu Xuan had seen a lot of such ruins along the way, and they should all be the remains of the immortal gate left by human monks three thousand years ago, but this place was beyond Lu Xuan's expectations.

The ruins and ruins still have a relatively intact mountain gate.

There are four big characters on the mountain gate.

Leaving the Sword Sect......

Although Ge Lin said that the mountain gate of the Leaving the Sword Sect was in the Tushan Kingdom, Lu Xuan was not surprised to see the mountain gate of the Leaving the Sword Sect here.

The Leaving Sword Sect should have moved into the Tushan World later, and this is the true birthplace of the Leaving Sword Sect.

The Leaving the Sword Sect three thousand years ago was obviously not trivial, this ruined wall was hundreds of miles wide, and even the mountain protection formation still remained. There is a demon clan that fights against the blood demon according to this, but the situation is also precarious.

Chengyun Ancestor destroyed the blood demon as always, and sent those hundreds of demon clans into the Xiyang furnace. When Lu Xuan was about to leave with Chengyun Ancestor, he felt the golden needle move slightly.

During this time, the golden needle has always pointed to the depths of the abyss, and it has never changed.

Lu Xuan didn't know what was in the depths of the abyss, but the reaction of the golden needle was unprecedented, since he had discussed it with Chengyun Ancestor once, Lu Xuan wondered if this golden needle was referring to the forbidden place guarded by immortals three thousand years ago?

It is said that under the Spirit River there, there is a treasure conceived by heaven and earth......

However, now that the golden needle has moved, it means that there is something in the ruins of the Sword Sect.

Lu Xuan asked Chengyun Ancestor to wait for a while, and followed the golden needle to a piece of rubble.

The golden needle pointed to the ground.

Lu Xuan immediately escaped underground and soon found something.

It was a black-red spirit sword.

This spirit sword should have gone through three thousand years, but it is still cold and shining, and the aura is sufficient, and it is obviously a top-grade spirit sword.

Lu Xuan casually put the spirit sword into the ten-mile bracelet.

It's a pity that Ge Lin is still in the Ghost King Boundary Monument now, otherwise he would be very excited if he could see the real mountain gate of the Sword Sect with his own eyes. Since this spirit sword is a thing of the Sword Sect, it will be handed over to Ge Lin or Wang Qing in the future.

Ge Lin is kind to Lu Xuan, this spirit sword can't be repaid at all, what Lu Xuan hopes most now is when he can help Ge Lin and bring him back to life.
