Xu Yan's speculation is a bit fanciful, and no one may believe it, but he himself knows that this guess is likely to be the truth.

Others don't believe it because others don't know about the existence of Yun Xianjun.

If someone has seen the Immortal Monarch Song and the Fish Belly City in the belly of the Feather Giant Whale, the Demon Flower Teleportation Array and the evil spirit in the Demon Flower Palace, and the stone wall that can isolate the origin of true fire, I am afraid that they will have to believe it.

The means that are not even as good as the scattered immortals, the mysteries to the amazing demon refining demon martial arts and demon swords, and the Yunxian Jun gathered by all kinds of clues is comparable to a true immortal in Xu Yan's opinion.

That's why he thought that Yun Xianjun came from outside the sky on the strange treasure that formed the Sword King Palace, so this strange treasure had a sturdiness that couldn't even burn the flame origin, and it could instantly suck the world's weapon slaves in.

"What kind of material is this, if it is refined into a weapon, wouldn't it even be inferior to the Innate Spirit Treasure...... Could it be the material of the Heavenly Spirit Treasure?"

Xu Yan, who was surprised, was taken aback by his guess again.

If such a large Soul Hell was completely constructed with a material that could refine the Mixed Heaven Spirit Treasure, then the person who sacrificed this strange treasure was really too arrogant.

"No, if it is a precious material, it is impossible for Yunxian Jun not to carry it with him, and the worst thing should be refined into a strange treasure with Yunxian Jun to fight, so it was left in the Sword King Mountain, and it was regarded as the Sword King Hall by later generations, and it looked like it should be a useless thing. ”

Xu Yan knocked on the stone wall, raised his hand and shot a needle, and the sword dragon only made a crisp sound and returned in vain, cutting the stone wall in the slightest.

"Elder, let's go quickly, it's gloomy here. Sure that he could move around without restraint, he immediately urged, he never wanted to be sucked into the soul prison again in his life.

"Try mobilizing the king crab, it's changing outside, if you want to survive, it's better to call more helpers." Xu Yan put Xiaoqing into Qianji Mansion and left Haida Tong outside.

"It's not far from the sea?"

Haida Tong asked suspiciously, and when he learned that Sword King Mountain was in the center of the Xizhou Domain, he immediately hung his head, and said: "It's too far away from the sea, and I don't know if there is a king crab clan near Xizhou, I am only in the Great Demon Realm, I may not be able to call it, if there is a Sea King Order, I may be able to try." ”

Xu Yan raised his hand and threw the Sea King Order over, but he didn't move the token at all.

"You do your best, hundreds of demon lords led hundreds of millions of demons to attack Xizhou, I'm not afraid, you also said that you are a big demon, don't be affected by the melee between demons and humans, if you die, what can Xiaoqing do." ”

"Yes, if I die, won't Xiaoqing become a widow, hey...... No, Elder, can't you just take me into the Qianji Mansion! I can live and die with Xiaoqing!" Hai Datong was smart once, Xiaoqing went back to the Qianji Mansion, why didn't he follow in.

"There's no place in the Thousand Machines Mansion. Xu Yan turned around and left, saying, "I'll help you open the way, you just follow behind, stay away, this road will not be peaceful." ”

"Okay, I'll be careful, Elder, you'll be careful, we'll be able to straighten our backs when I call the King Crab Clan." Hai Datong nodded hurriedly, put away the Sea King Order, and sneakily hid in the corner to observe the situation, he needed to leave the Soul Prison before he could use the Crab Clan's talent to call his fellow clansmen.

Walking out of this special prison, Xu Yan walked towards Moxi, who had blocked the passage, and in the palm of his hand that was turned upside down, he grabbed the sword dragon that changed into the size of a needle.

"Sure enough, it's a brother, I came here from Beizhou to save me, and I will never forget this friendship in my life......."

Hai Datong hid in the corner with emotion, and attached more importance to Xu Yan's brotherhood, and suddenly remembered the wide Qianji Mansion, and wondered: "There is no place, how can there be no place in the Qianji Mansion?"

At the entrance of the passage, Moxi, who was impacted by countless monsters, could only resist with his big mouth.

He devoured the blood spirit, and now he has not completely refined, and he has lost his combat ability, but it is not difficult to block the intersection, and some monsters in the Great Demon Realm are impacting, and Moxi, one of the eight demon spirits, does not care.

"Let these monsters in and kill them in one fell swoop. ”

The voice of the devil's ghost face came, and Moxi immediately retreated, and quickly exited the passage, but the big demon monsters in the passage did not rush in, but were blocked by layers of solid ice.

"Mako-sama's talent for ice and snow is truly extraordinary, and the more you look at it, the more it looks like a Terran spell. Moxi stared at the ice in the passage and said gloomily, his tone a little strange.

"The Eight Great Demon Spirits are not simple, they are so far away, and you can still hear some secrets through my prohibition, your ears are very smart, Lord Moxi. ”

Xu Yan suddenly provoked a sly smile and said: "The news you heard is actually another strategy, I guess you also saw the guy in the corner, he is a chess piece sent to Xizhou many years ago, the purpose is to plot against the soul warden Shen Tu Liancheng!"

Who would have thought that the Soul Warden, who is loyal to the Sword King Palace, would fight back at a critical moment and help us hit the most difficult masters in the human race, and then my demon clan will be able to occupy the Sword King Hall in one fell swoop and become the master of Xizhou!"

Mo Xi didn't look at resisting the monster, and with his back to Xu Yan, he could use the demon spirit body to sense Xu Yan's movements and even his voice.

The stone wall rose, Xiaoqing and Hai Datong appeared, and the white crocodile and Heixin and others who were far away in the third hall could not see it, but Moxi was aware of it, and when he heard Xu Yan say this, he felt even more puzzled.

"What price did Lord Ghost Face use to make Shentu Liancheng turn against him, that traitor and my demon clan are incompatible, and it is impossible for him to return to the demon clan!" Mo Xi said in a deep voice.

"You also know that he won't return to the demons, and he listened so carefully, in fact, I made it all up. Xu Yan smiled, during the time he was talking to Moxi, strange black lines had already been intertwined into a big net, sealing all the retreats of Moxi.

"You're lying to me!" Moxi was startled, and opened his mouth to spew out undigested blood spirits.

He already felt that something was wrong with the devil's face, and he sensed the danger coming, as long as he got rid of the blood spirit, he could use the power of the eight demon spirits to protect himself.

"yes, I'm lying to you. ”

The sly smile on the corner of his mouth was abnormally cold, and Xu Yan's voice became gloomy: "But I can really find traces of the four kings in the soul prison, I didn't lie to you, you see, the four kings are here!"

As soon as the Four Kings came, the black lines around them suddenly turned into demonic souls, roaring and forming a terrifying seal.

In the seal, the souls of the four demon kings were as hideous as ghosts, entangled and bit Moxi.

"The soul of the four kings! This is the soul of the four kings!! ghost face !!"

The wailing sound could not be transmitted from the Demon Soul Array formed by the Heavenly Demon Dance, especially the existence of the soul of the Four Kings, which was a natural enemy for a demon spirit like Moxi.

The eight demon spirits are all spirits, although each of them is extremely strong, after all, they can't compete with the soul of the demon king, and soon in the wail, the demon spirit was torn to pieces, and finally fused into a demon soul that was refined by Xu Yan.

"Who's next, Sparrow, isn't your opponent interesting? ”

At the end of the mountain, in the depths of the Soul Prison, in this no-man's land, the Seventh Demon Son finally stretched out his claws, revealing a terrifying hideousness.
