After Nan Tianyun's death, Nan Qi took over the Wu Nan Sect, and under Nan Qi's management, everything in the Wu Nan Sect was slowly on the right track.

And Nan Qi sent dozens of disciples to the various sects in the Heavenly Rain Empire, explaining that the incident of unlocking the seal of the Flame Demon thirty years ago and this time was the mastermind of Nan Tianyun, a rebel of their Wu Nan Sect. Now that Nan Tianyun has been corrected by their Wunan Sect, Nan Qi apologized to all the major sects for what Nan Tianyun had done, hoping that the various sects could resolve their conflicts with the Wunan Sect and get back together.

Seeing what Nan Qi did, Zhou Tianlong also secretly praised it. After all, the only people who knew the truth about the Flame Demon Seal being unlocked were these few people from their Heavenly Rain Sect, as long as they didn't tell it, others wouldn't know the truth of the matter, and they thought that the Flame Demon was the seal they broke through, so they wouldn't blame it on the head of the Wunan Sect at all.

However, Nanqi dared to act boldly, and admitted his mistakes to all the sects in the empire. Zhou Tianlong expected that as long as he was a decent family, he would no longer blame Wu Nanjiao, after all, the culprit was Nan Tianyun, and the others did not know, and although Yu Yuanfang's father and son were the culprits, they were actually victims, and they also paid a heavy price for unlocking the seal of the flame demon, which could be regarded as a punishment for them.

After seeing that everything was taken care of, Zhou Tianlong told Nanqi that he was going to the black prison of the Wunan Sect. Nan Qi was very puzzled, not understanding what Zhou Tianlong was going to do. But Zhou Tianlong didn't tell him the reason, and just went to the black prison alone.

After entering the black prison, Zhou Tianlong once again followed the tunnel and came to the entrance of the underworld.

Because he once promised Yin Huo that after the Yan Demon was subdued, he would return the Fire Pill to Yin Huo, so naturally he couldn't break his promise. Now that everything has been resolved, he should also send the Fire Pill to the Underworld as soon as possible to fulfill the wish of the Yin Fire.

Yin Fire and the Fire Demon coexist, so it had long known about the Fire Demon being subdued. Now, Yin Huo was naturally very happy to see that Zhou Tianlong was really true to his word.

"Senior, how can I use this fire pill?" Zhou Tianlong took out the blue sphere from the space storage bracelet and asked Yin Huo. And with the removal of that blue sphere, an extremely rich fire attribute energy suddenly spread throughout the entire cave entrance.

"You can just put it there, and I can take care of the rest myself!" Yin Huo said.

Zhou Tianlong put the fire pill on the ground, then withdrew a few steps and quietly looked at the yin fire.

I saw that the blue flames that kept flying out of the Yin Fire body were as if they had suddenly received a huge traction, and they flew towards the blue sphere together. And with the injection of those blue flames, the blue sphere suddenly bloomed with dazzling light, only forcing Zhou Tianlong to not open his eyes, he could only squint and watch carefully.

The flames in the Yin Fire body continued to fly out one after another, all of which were injected into the blue sphere, and the blue sphere became brighter and brighter, and finally, the blue light spread throughout the hole.

"The Yin Fire is gone!" Zhou Tianlong was secretly surprised, because he found that the huge blue flame that had been burning there had actually been all injected into this small fire pill the size of a baby's fist at this moment. Such a small fire pill was infused with such a huge flame, and the degree of violence of the energy contained in it can be imagined.

At this moment, a dazzling blue light bloomed from that fire pill, like a fierce sunlight, causing Zhou Tianlong to involuntarily close his eyes.

"Boom!"

An earth-shattering loud noise came, and Zhou Tianlong only felt that the entire cave entrance shook violently, and he was unsteady on his feet, almost falling to the ground, and hurriedly held on to the wall next to him.

Zhou Tianlong was taken aback, and hurriedly opened his eyes, only to see that at this moment, in front of him, a large area of blue gas was diffused, blocking all his vision, and those blue gases actually contained extremely terrifying high temperatures.

"What's going on?" At this moment, Zhou Tianlong suddenly felt that the fire attribute true qi cyclone in his body began to rotate violently, and then, as if it had been subjected to a huge traction, these blue gases continued to rush towards his body, and then followed the pores of his body and injected into the fire attribute true qi cyclone in his body.

"Hahahaha!" An old voice came out from the large area of blue gas: "These blue gases are also the flames in my body, and they are of the same origin as the fire attribute true qi in your body, so they will naturally be absorbed by you!"

Zhou Tianlong nodded slightly, and hurriedly sat on the ground at the moment, urging the rotation of the fire attribute true qi cyclone with his mind, and began to continuously absorb those blue gases;

And as the blue gas was continuously inhaled into Zhou Tianlong's body, the sight here gradually became clearer. Zhou Tianlong suddenly found that at this moment, in front of him, there was actually a middle-aged man.

The man looked to be only in his forties, with thick eyebrows and big eyes, a straight nose and a square mouth, and he was wearing a royal blue shirt, and his skin was faintly shining with blue light.

"Are you a Yin Fire senior?" Zhou Tianlong remembered that the last time he came here, Yin Huo had told him that as long as he had the Fire Pill, he could turn into a human form. But now that he saw it with his own eyes, Zhou Tianlong still felt a little shocked, he didn't expect that a flame could also have life and turn into a human being.

"Why? You don't know me anymore?" Yin Huo asked.

"How is it possible?" Zhou Tianlong hurriedly smiled, but secretly said in his heart: "There is no one else here at all, even if you think with your ass, you know that it is you, how can you not know the reason?"

"Yin Fire senior, your strength ......" Zhou Tianlong was secretly surprised, because he could clearly feel an extremely powerful aura from Yin Huo's body at this moment, and this aura far surpassed the martial artists of the Emperor Martial Realm such as Nanqi and the Fire Refining Demon Bear, and even surpassed the top Emperor Martial Realm masters such as Yu Qianyu and Shishi.

"This feeling ......" Zhou Tianlong's eyes lit up suddenly, and he remembered someone. That person was Elder Zou who had rescued Yi Tian from the graveyard of the dead. He is the strongest person Zhou Tianlong has seen so far, of course, in a sense, he is not a person, just a skeleton.

Zhou Tianlong felt that the aura of yin fire at this moment was basically on the same level as that Elder Zou.

"Could it be...... This is the realm above the Emperor Martial Realm!That is, the legendary Immortal Martial Realm!" Zhou Tianlong's eyes widened suddenly, and his heart was full of shock. You must know that the martial artists of the Immortal Martial Realm, in the entire Holy Martial Continent, are all top-notch existences, and they are beyond the reach of the vast majority of martial artists.

"What kind of characters are there in this underworld?, or what kind of things?" Zhou Tianlong was secretly surprised. Because he knew that Yin Huo was just guarding the entrance to the underworld, and to put it mildly, it was just a gatekeeper. And a gatekeeper can have a strength close to the peak of the entire Shengwu Continent, Zhou Tianlong really can't imagine how powerful the people in the underworld, or rather the ghosts in the underworld, have.

"Hmm!" Seeing that Zhou Tianlong was surprised by his strength, Yin Huo just nodded, and then said lightly: "As long as the Fire Pill returns to my body, my strength will be restored!"

As for its specific strength, Yin Huo did not tell Zhou Tianlong in detail.

"Zhou boy, this time thanks to you, I have recaptured the Fire Pill, this friendship, I have written it down!" Yin Huo smiled and said to Zhou Tianlong: "Although you also became a three-attribute martial artist because of me, later you subdued the Flame Demon, and your strength has also been greatly improved." But after all, I still owe you, because if there is no fire pill, my strength will never be restored, and you are equivalent to saving my life!"

As he spoke, Yin Huo suddenly raised his hand, and Zhou Tianlong saw that on the palm of his right hand, a blue sphere suddenly bulged, as if a blister had emerged in the water.

"Bang!" came a muffled sound, and the blue orb seeped out of Yin Huo's palm, and then levitated directly above his palm.

"It's so weird!" Zhou Tianlong was secretly surprised, not knowing what this blue sphere bulging out of the Yin Fire Body was and what kind of effect it had.

Yin Huo grabbed the blue orb, then put it in Zhou Tianlong's hand, and said to him: "You put this thing away! When your life is at stake, you can crush it, and it will naturally be able to save your life!"

"It's so amazing!" Zhou Tianlong nodded, and then without asking more, he put the blue sphere into his spatial storage bracelet.

Seeing that the fire pill had been delivered and the Yin Fire had turned into a human form, Zhou Tianlong knew that his mission had been completed, so he said goodbye to the Yin Fire again. And Yin Huo didn't keep it, because it knew that in this place where ghosts cry and wolves, as long as it is a normal person, it will never want to stay here.

Yin Huo found another skeleton and asked it to throw Zhou Tianlong out along the passage. It's just that this time is different from the last time, the place where Zhou Tianlong landed was not in the Red Flame Valley, but in the black prison of the Wunan Sect.

"This underworld is really weird!" Zhou Tianlong was puzzled, and didn't understand why he left the underworld twice, leaving from the same passage, but would appear in different locations on the ground.

Of course, Zhou Tianlong didn't have the heart to think about these things carefully now, because he knew that he still had a very important, even urgent, thing to do.
