At this moment, the shock in Zhou Tianlong's heart was completely indescribable, and what he saw and heard today had completely subverted his view of the world.

Originally, Zhou Tianlong thought that the reason why people thought that the Yan Demon was transformed by the Yin Fire under the Nine Shadows was because people saw that the strength of the Yan Demon was extremely strong, so they made up a story about its origin without authorization, so as to make it appear more mysterious, and also find a high-sounding reason for people to be unable to defeat the Fire Demon.

And in Zhou Tianlong's cognition, or in the cognition of the vast majority of people who are similar to him, there is no world under the Nine Shadows, which is what everyone usually calls the "underworld".

But Zhou Tianlong never dreamed that the legend about the fire demon turned out to be true, not only did he see the yin fire under the nine shadows that gave rise to the fire demon, but the space in front of him made him have to believe that this was the underworld that he had always thought only existed in the legend. He didn't have to wait for the yin fire to answer his question, just the sound of ghosts crying everywhere was enough to show that his conjecture was absolutely correct.

At this moment, Zhou Tianlong can truly understand what it means to be "the great and strange of the world", as long as he can think of things, in this world, it is possible that they really exist.

Hearing Zhou Tianlong's words, Yu Feilin's delicate body also trembled violently, and then looked at the yin fire nervously, waiting for its answer.

"Ha Lu Ha

Zhou Tianlong swallowed his saliva and subconsciously shook his head. It's better not to go to that kind of place, because once you go, you can't come back.

Yu Feilin was already stunned at this moment, and he never dreamed that there really was an underworld in this world, and his pretty face suddenly turned pale with fright.

"What happened on this day is really bizarre, I'm afraid that if I say it, almost few people will believe it!" Zhou Tianlong's face was full of wry smiles, he never dreamed that the black prison of the Wunan Sect would be connected to the underworld, this kind of thing, it is estimated that even Nan Tianyun himself does not know the way!

"But what is this for?" Even if Zhou Tianlong racked his brains, he couldn't understand why the Wunan Sect would have something to do with the underworld. As for this problem, it is like the lake in the Tianyu Mountain Range, why is it connected to the lake in the snowy ice field, but I am afraid that ordinary people can't explain it at all.

"Behind that black earthen wall is the underworld. So in other words, senior, you are the entrance to the underworld?" Zhou Tianlong asked Yin Huo. He didn't know what to call Yin Huo, so he had to call it "senior", after all, people have survived for tens of millions of years, and when it comes to age, they are too much older than themselves.

"That's right!" said Yin Huo, "each of the dozen or so caves you have seen can be connected to the underworld. And at each cave entrance, there is a yin fire guard, the purpose of which is to protect the safety of the underworld, so as to prevent idle people from entering the underworld. ”

"Idle people waiting to enter the underworld?" Zhou Tianlong secretly pouted: "This underworld also needs to be protected?

"If I'm not mistaken, senior, you are the leader of these Yin Fires, right?" Zhou Tianlong asked. He found that among these caves, only this cave had the largest area, and only this cave emitted light, which showed that the yin fire in the other caves was far less powerful than this yin fire, so he concluded that this yin fire was the leader of the underworld yin fire.

"The kid really has good eyesight! Among the eighteen Yin Flames at the entrance of the Underworld, my strength is the strongest!" the Yin Flame Ha Lu Ha laughed, with a hint of conceit in his tone.

"Originally, with my strength, there shouldn't be any problem in cultivating into a human form. But just as I was about to take shape in my cultivation, a flame in my body suddenly snatched away my Fire Pill. Therefore, I can only have the intelligence of a human being, and I can speak like a human being, but I can't transform into a human form at all, and I can't have great strength. If someone comes to attack the underworld now, I'm afraid I won't be able to defend at all, but fortunately, in the past 10,000 years, this place has been relatively peaceful. Yin Huo said again, with a hint of loneliness and even resentment in his voice.

"There are really people who have attacked the underworld!" Zhou Tianlong was taken aback. Originally, he thought that the Yin Fire was just a form of guarding the safety of the underworld here, but he never dreamed that there was such a thing as attacking the underworld.

"Who is so bold?" Zhou Tianlong was very puzzled, according to common sense, once a human being enters the underworld, it is impossible to come back.

"Could it be that there is really such a powerful person in this world who can go back and forth freely in the underworld?" Zhou Tianlong didn't know, he didn't know if the Immortal Martial Realm, the Divine Martial Realm, and even the legendary Saint Martial Realm master could have such a powerful strength.

"What is the Fire Pill?" Zhou Tianlong asked Yin Huo.

"The so-called fire pill is the source of the flame in my body. Once I lose the Fire Pill, my strength will be greatly weakened. So although on the surface, my flames are brighter than the yin flames in the seventeen caves around me, but that is because I have survived longer than them, but in fact, my strength is far inferior to theirs. Yin Huo explained to Zhou Tianlong.

"I see!" Zhou Tianlong nodded and said, "So you, who have lost the Fire Pill, will never be able to cultivate into a human form." On the contrary, the flame that took away your Fire Pill, it cultivated into a human form, and it is what we humans call 'Fire Demon'. ”

At this moment, Zhou Tianlong finally figured out the true origin of the Flame Demon. Originally, the Flame Demon was also the same as the blue flames in it, but with the fire pill of the Yin Fire, it escaped from the underworld and entered the human world.

"Yes, those flames of the underworld will cease to exist after leaving the underworld. But with my Fire Pill, the Fire Demon not only survived, but also possessed great strength!" Yin Huo said hatefully. Originally, everything that the Fire Demon had today should belong to it, so it naturally hated the Fire Demon in its heart.

"Just now, the senior said that if we are a fire attribute martial artist, we can fulfill your wish for you and take back that evil obstacle, I don't know what this means?" Zhou Tianlong asked again.

Zhou Tianlong knew that the seal of the Flame Demon should be unlocked by Yu Zihua soon, and when the time came, the Flame Demon would ravage the entire Tianyu Empire again. If you can find a way to subdue the Yan Demon with the least sacrifice, then you can not only fulfill the wish of Yin Huo, but also avoid the catastrophe of the Tianyu Empire, so Zhou Tianlong is naturally more interested in this topic.

Yin Huo said again: "If you are a fire attribute martial artist, I can inject one of my flames into your body, and you can refine it into your own true qi. The fire demon is the flame in my body, and it lives with the flame I input into your body, and when the time comes, as long as you run that flame, the fire demon will be included in your body. This can not only eliminate harm for the people, but also enable you to greatly improve your cultivation by refining the Flame Demon. ”

"Oh?" Zhou Tianlong's eyes suddenly raised, and a light flashed in his eyes. If you follow the method of Yin Fire to subdue the Flame Demon, it must not be a difficult thing, and the various sects will not suffer any casualties.

"Who should this fire attribute martial artist look for?" Zhou Tianlong thought to himself. This matter can be described as a great opportunity, how powerful the energy in the body of the Flame Demon is, once refined, this person's strength must be greatly increased, which will be of great benefit to him.

"But ......" Zhou Tianlong thought of another question: "Even if we can find such a person, then how can we bring him here? More importantly, to find such a person, at least the two of us should go out first, but how should we get out of here?"

Just when Zhou Tianlong was thinking about who to give this opportunity to, Yin Huo suddenly said to him: "Boy, when those bones outside were about to attack you just now, what happened to the dragon groan in your body?"

Zhou Tianlong hesitated slightly, and did not deliberately hide it, so he told Yin Huo that he had cultivated a magical refining body**, and that refining body** turned into a dragon-shaped pattern and stayed behind him, and the dragon's groan was emitted by that pattern.

"There is an extremely powerful coercion in your dragon groan, as if it were the breath of an ancient dragon. And that kind of coercion, in the final analysis, comes from your martial arts!" Yin Huo said again.

Zhou Tianlong nodded. He knew that the True Dragon Quenching Technique and the Saint Martial Heavenly Dragon Technique were connected in one vein, and every time his Saint Martial Heavenly Dragon Technique was upgraded to a higher level, the dragon-shaped pattern transformed by the True Dragon Quenching Technique would become more powerful.

"You use the martial arts trick to show me!" Yin Huo ordered Zhou Tianlong again.

Zhou Tianlong didn't understand what Yin Huo was going to do, and he didn't shirk it at the moment, and the Holy Martial Heavenly Dragon Technique in his body was running. It's just that here, there is no heaven and earth aura, and the Holy Martial Heavenly Dragon Technique can't refine anything.

"Boy, are you a dual-attribute martial artist?" Yin Huo asked again.

Zhou Tianlong nodded: "Yes, it is the two major attributes of wind and water, but unfortunately they are not fire attributes, which cannot meet the requirements of the seniors, nor can they help the seniors fulfill their wishes." ”

Yin Huo fell into silence, and after a long time, it suddenly said: "If I forcibly attach the fire attribute to your body and make you a three-attribute martial artist, I don't know if you are willing to do it?"
