The clue about the Demon Emperor is the Demon Shadow from the bottom of the Tongtian River.

Xu Yan had already been able to conclude that Yan Tongtian's old enemy, Shentu Yuntian, had also rushed the remnant soul into the Mixed Yuan Bottle.

The soul of the Demon Emperor formed the snow-capped mountains on the Tongtian River, breeding barbarians, and the barbarian conquest all over the world was not to invade Qingzhou, but to find it.

Look for the remnant soul of Yan Tongtian, that is, Xu Yan.

The thousand-year-old preface said that Tongtian and the Demon Emperor died together, and the remnants of the two escaped into the Mixed Yuan Bottle, although the blood shadow was finally destroyed by Pang Hongyue, but it may not be really dead.

Because of the appearance of Tu Qingzhu, Xu Yan had an inexplicable sense of rivalry, and Tu Qingzhu's white snake, if it grew into a thousand Jiao, it would clearly be the jellyfish at the Qingzhou border back then!

Whether Tu Qingzhu and Shen Tu Yuntian are the same person or not, Xu Yan has no definite evidence, just a guess and inference.

However, if you want to confirm whether there is a connection between the two, it is actually simple, just ask.

There is no need to ask the subject, but to ask the Demon Soul Thousand Scales.

After a few days, when Xu Yan sensed that the spirit of the black dragon had recovered a lot, he once again merged into the dragon soul with the original spirit and appeared in the trapped dragon stone.

As soon as he found that Xu Yan's primordial spirit appeared, the demon king soul in the mist immediately became cautious, and the black mist shook and shrank into a ball.

"When did you let me go, I was already too weak to threaten you at all. ”

Although the Demon Soul Thousand Scales has not been devoured by the black dragon in the past few days, he is still terrified, it feels bad to be the food of the dragon's mouth, and the feeling of life and death in the hands of others is even more uncomfortable.

"The Demon King's mouth is wrong, your value lies in the true news, if you don't tell the truth, how can I let you go, I'm sorry, you can only be the food of the black dragon." ”

Xu Yan's tone was extremely indifferent, and at the same time, the black dragon let out a roar, and the dragon's teeth showed their edge.

"Why didn't I tell the truth! All the news I said is true, don't worry, I will never lie to you!" Thousand Scales immediately became anxious when she heard the dragon's roar, and hurriedly defended.

"Yes, then tell me about it, what enemies the Flame Demon Clan has, and whether there are frequent battles in the Northern Continent Region. ”

Xu Yan snorted, and did not question the true purpose of the other party's attack on the Dao Mansion, but asked about the news of the Flame Demon lineage.

Knowing the existence of the seventy-two pages of the Dao Scroll, the purpose of the Four Great Demon Kings didn't need to be asked at all, if it weren't for the Dao Scroll Treasure, Thousand Scales would not have gone to the Dao Mansion to fight hard.

"The Northern Continent has often fought battles, and the four demon kings are not in the same vein, although the four of us will not fight each other, but the clansmen under our hands often fight, we are demons and not humans, only by fighting can we improve our strength faster, and we can select the real strong, what's so strange about this, as for the Flame Demon vein, they are more special. ”

Thousand Scales' voice paused, and continued to speak.

"The Flame Demon is chaotic, similar to the Zerg, divided into two completely different races, the Green Flame Demon and the Red Flame Demon, the Green Flame Demon likes to inhabit the belly of the mountain underground, occupy a place, and continue to reproduce, while the Red Flame Demon likes to plunder and fight, and is home everywhere.

The Red Flame Demon is much more ferocious than the Green Flame Demon, not only killing other demons, but also the Green Flame Demon, sometimes there will be a desperate battle, the result of the vicious battle is usually two, if the Red Flame Demon is defeated, it will die in a life and death, and if the Green Flame Demon is defeated, it will be captured by the Red Flame Demon and become his own tool, used to breed more clansmen. ”

After hearing the strangeness of the Flame Demon Vein, Xu Yan suddenly realized that the red strange insects that attacked the Flame Demon Cave not long ago were the Red Flame Demon Vein.

It seems that the demons attack each other and fight each other are not uncommon in the Northern Continent Region, and listening to the tone of Thousand Scales, it seems that this situation is very normal in the eyes of the demons.

After listening to the explanation, Xu Yan nodded with satisfaction, and suddenly asked, "Who is the purple mandarin." ”

Hearing the name Purple Mandarin, the demon soul mist of the thousand scales shook significantly, which meant that he was also surprised.

"How do you know the name Purple Mandarin?" the Demon Soul Thousand Scales asked rhetorically.

"You only have the qualifications to speak, not to ask. Xu Yan's voice came coldly: "Don't forget your situation, Lord Thousand Scales, you are not a demon king now, but fish and meat, and the sword is in my hands." ”

The demon mist shook again and fell silent, but soon it made a sound again.

"Purple Mandarin is one of the Demon Emperor's concubines, she is the body of the human race, and she is also the biological mother of Shentu Liancheng, who was killed by the Demon Emperor in front of Shentu Liancheng with his own hands. ”

Knowing that the purple duck was Shentu Liancheng's mother, the black dragon's eyes immediately burst with Sen Ran's killing intent.

"I see...... The name of the purple duck must be known to very few people, and even Shentu Liancheng himself may not want to mention it. Xu Yan's voice was full of coldness.

"No one likes to uncover their scars, and few people know about the Demon Emperor's colorful human race, because they don't live long, and they are just tools to the Demon Emperor. ”

The demon soul thousand scales said calmly, in fact, the women of the human race are all tools to the demon race, and they can be killed at will.

"That's right, they are really the same person......" Xu Yan's whisper had a cold breath, and he couldn't hear it inexplicably, and he didn't know who was the same person as whom, let alone dare to ask more.

The Demon King Thousand Scales is very smart, he knows the truth that people have to bow their heads under the eaves, and he also knows that he must endure before escaping, and he also knows that at the right time, he secretly emitted a second wisp of demonic energy to entangle the black dragon.

Thousand Scales knew a lot, this kind of demon king's soul could be called an old treacherous and cunning, but he didn't know that the guy who gave him a glimmer of hope had no intention of letting go of his great supplement from the beginning.

The same person Xu Yan said was the Demon Emperor Shen Tu Yuntian and Tu Qingzhu from Yongwang Peak.

In the ruins of Danfu, Tu Qingzhu once used the word purple duck to deter Shentu Liancheng, and even made Shentu Liancheng look at him angrily, and now that he learned the true identity of Ziyuan, Xu Yan concluded that Tu Qingzhu was the demon shadow of Tianhe Bay, and the remnant soul of the demon emperor Shentu Yuntian!

"Sure enough, it's you, Tu Qingzhu, I should have killed you together in the Gu Kingdom for ten years, it seems that the master of Yongwang Peak is more auspicious, and Nangong Yongwang is afraid that it has fallen. ”

Xu Yan was thinking to himself, and suddenly he was puzzled again.

"Nangong Yongwang is the top ten masters of the Hundred Gods List, a strong man at the peak of the gods, how could he be killed by Tu Qingzhu, a guy in the Yuanying realm, if Nangong Yongwang is not dead, in what form will he become Tu Qingzhu's protector, or Tu Qingzhu still has a demon powerhouse behind him, secretly controlling Yongwang Peak......"

The current situation of Yongwangfeng's vein became confusing, Xu Yan pondered for a long time, and couldn't figure out the key, but he always felt that Yongwangfeng was hiding a lot of conspiracy.

"Thousand Scales, do you know where the whole text of the Demon Refining Method is. After being silent for a while, Xu Yan asked again, he sensed a wisp of demon soul entwined by the other party, but he pretended not to know.

"The method of demon refining is in the Demon Emperor City, engraved in the center of the tree god crown. Thousand Scales can be said to have answered all questions, but his mind is not on these news, but carefully controlling the wisps of demonic energy with the power of divine souls.
