The sea of fire that the divine fire turned into engulfed the Purgatory King in an instant.

"Ahh

A terrible scream came from the sea of fire, and it was clear that the Purgatory King could not resist the burning of the divine fire.

Seeing this, Lin Fang and Yuan Mingda, who had already prepared, almost did not hesitate at all, a dragon roar resounded through the heavens and the earth, and the divine dragon phantom was added by the golden seal, hovering around the sea of fire, just waiting for the sea of fire to fade and give the Purgatory King a fatal blow.

As the sea of fire faded, Lin was relieved to move, and the Divine Dragon Phantom quickly rushed towards the Purgatory King in the next moment.

The Purgatory King was already hit hard by Fang Fengting's taboo killing move, and his body was pitch black and unrecognizable.

The sudden powerful impact of the Divine Dragon Phantom, he didn't have time to defend at all, and his body was instantly pierced back and forth by the Divine Dragon Phantom, and his vitality finally came to an end at this moment.

"Peng!"

The body of the Purgatory King, who followed him, fell to the ground weakly.

Seeing this, the purgatory king's subordinates who were not far away immediately dispersed.

"Feng Ting, how are you!"

Lin Fang ignored the evil people who escaped, and came to Fang Fengting's side as soon as possible.

Fang Fengting performed a forbidden trick, and she also suffered a serious backlash, her face was pale, and she was injured inside her body, and she couldn't heal in a short time just by relying on ordinary pills.

"Quick, this is the Dragon Tiger Pill!" Lin Fang handed over a pill, this Dragon and Tiger Pill could at least stabilize Fang Fengting's injuries and speed up the recovery of internal injuries on his own.

After Fang Fengting swallowed the pill, she showed a smile and muttered, "It seems that this Purgatory King is nothing more than that, and he was killed by us like this!" ”

Hearing this, Lin Fang didn't know what to say. If they even used the forbidden trick and couldn't kill the Purgatory King, then they probably wouldn't have much chance to kill the Purgatory King, and they might even die here.

"Sister Feng Ting!"

Han Xiaoqing and Yuan Mingda also came over, looking at Fang Fengting with concern, neither of them went to chase and kill the purgatory king's escaped men.

"I'm fine, now that the Purgatory King is dead, let's hurry up and find the Holy City Key!" Fang Fengting said to Lin Fang and the others.

"Good!"

Lin Fang nodded, and then said to Han Xiaoqing, "Xiaoqing, you take care of Feng Ting." ”

"Well, leave it to me!" Han Xiaoqing felt that she was the only one who didn't contribute in this battle, and Fang Fengting was injured in order to kill the Purgatory King, of course she was willing to take care of Fang Fengting, and she should have contributed.

Soon, Lin Fang found the Holy City Key from the Purgatory King. Other than that, Lin Fang didn't gain much, especially the elixir that Lin Fang wanted to find to treat his injuries.

"This Purgatory King's strength is extraordinary, but he has so few belongings?" Lin Fang frowned slightly, in addition to the Holy City Golden Key, the black long sword on this Purgatory King was worth hundreds of thousands of high-grade spirit stones, and the others together were only hundreds of thousands of high-grade spirit stones.

This bit of belongings can't stand his identity as a four-elephant celestial, not to mention that he still has so many younger brothers under him. No matter how you look at it, it looks like a hegemon.

"Brother Lin, the Purgatory King's underground palace is here. Perhaps, all his good things are left in the treasure house of the underground palace. Yuan Mingda also felt a little strange, and then pointed to the underground palace not far away and said.

At this moment, with the death of the Purgatory King, those little brothers had already gone for their own lives, so the huge underground palace was actually empty, and no one guarded it.

"Let's go check it out!" Lin Fang nodded, but he didn't have much hope. For a strong person like the Purgatory King, the best thing is, of course, to be able to feel at ease by carrying it close to him, and most of the things that are placed in the treasure house are inconsequential objects!

"Good!" Yuan Mingda nodded, and then followed Lin Fang towards the underground palace.

"Sister Feng Ting, let's go in and have a look!" Han Xiaoqing said to Fang Fengting, Fang Fengting nodded, and with Han Xiaoqing's support, the two also walked towards the underground palace.

This underground palace is indeed resplendent and extremely luxurious. There are a lot of precious materials in it, if it is placed in Daqin, such a palace is definitely no worse than the nest of any of the four major families.

However, Lin Fang couldn't look down on these things, and they didn't have so much spare time to disassemble these materials. So, go straight all the way and walk towards the depths of the underground palace.

Shuttle all the way, all kinds of underground palaces emerge in endlessly, but from the perspective of the pattern, from the external decoration, you can distinguish the light and heavy.

"That central hall should be the palace where the Purgatory King lives." Yuan Mingda pointed to the tallest and most extravagant palace in the center in front of him and said.

"Hmm!" Lin Fang nodded, and then walked into the palace.

The four of them walked through the front courtyard of the palace and came to the small courtyard where the Purgatory King lived his daily life. Finally discovered the Hellmaster's treasure trove. The door of the treasure house was locked, but it was easily forced open by Lin Fang.

There are a lot of treasures placed in this treasure house, but the value of these treasures is really not flattering, although the combined value is hundreds of thousands of high-grade spirit stones, but Lin Fang is not very happy.

Just when Lin Fang was about to return in disappointment, he suddenly heard a shocked voice from Yuan Mingda: "Brother Lin, hurry, come and see!" ”

"What's wrong?"

When Lin Fang heard this, he hurriedly ran over, but when he walked over to take a look, his face suddenly changed greatly.

"It's ......"

Lin Fang was shocked.

"Brother Lin, this is the Netherworld Spring!"

Yuan Mingda said excitedly.

"That's right, it's the Nether Spring!"

Han Xiaoqing and Fang Fengting, who came later, also looked at the spring in front of them in surprise, the spring water had a rich black gas, but it was full of aura.

"Brother Lin, what should we do? For us, this Netherworld Fountain will not only not work, but will do great harm. Yuan Mingda looked at Lin Fang and asked what Lin Fang meant.

Lin Fang stared at the Netherworld Springs in front of him, these springs had magical effects, and they were much more precious than the Ten Thousand Spirit Water. However, this kind of spring water was not suitable for Lin Fang to cultivate, because such a power would have a great conflict with the power in their bodies.

According to the lineage, the Netherworld Spring can only be used by those who have cultivated the evil law, or who have cultivated to the realm of Infinite Celestials, and can make their cultivation twice as effective with half the effort. Moreover, if you can form a Netherworld Spring, then there will probably be Netherworld Source Stones underneath this spring.

The Netherworld Source Stone, its preciousness, was even more precious than the Xuanyin Liquid that Lin Fang had encountered at the beginning. They are all legendary treasures that were only recorded in the Flood Era, and even for the Infinite Celestials, they have certain benefits.

Of course, the Netherworld Source Stone is also extremely evil, and ordinary people who take it are likely to be controlled by the Netherworld Source Stone, and eventually become an unconscious monster. Such a treasure, those who have the ability to take it, the weakest are the strong people in the realm of the unity of the four elephants, so that they can control the evil power in it and not be eroded by it.

"No wonder the Purgatory King was able to raise so many strong people, it seems that it is inseparable from this Nether Spring. It's a pity that this Netherworld Spring is destroyed, and I don't know if I can take it away. If you can't take it away, destroy it! Lin Fang said.

"Okay, I'll try!" Yuan Mingda nodded, and then prepared to take all the spring water away.

But soon, they found out that they couldn't do it. As soon as these Nether Springs leave, they will turn into a puff of black gas and dissipate into the air.

"It looks like I can't take it away!" Yuan Mingda said helplessly.

"Then destroy it!" Lin Fang said without hesitation: "I don't know, under this Netherworld Spring, there is no Netherworld Source Stone. ”

As he spoke, Lin Fang instantly cast the Divine Dragon Phantom with all his might. A powerful force burst out, and the entire spring was shattered in an instant, followed by those nether springs flowing around, and as soon as they left the range of the spring, they would immediately dissipate.

Obviously, this Netherworld Spring cannot leave the spring, and once it leaves, it will leave and dissipate if it is not preserved by a special method.

In the blink of an eye, the originally full spring water dissipated in a short period of time, turning into a rich black gas, which continued to rise. Soon, the bottom rock of the spring was revealed.

"Break it for me!"

Lin Fang struck again, bombarding the rocks below the spring.

"Peng!"

The power burst out, and the rock was torn apart, and a huge hole was blasted. Among these rock fragments, a black crystal stone the size of an egg shines exceptionally among the surrounding cyan rocks.

"Nether Source Stone!"

"There really is a Nether Source Stone!"

When Yuan Mingda and others saw this, they were all overjoyed. Such a legendary treasure is of immeasurable value, which is the biggest gain of their trip. If this thing falls into the hands of someone who cultivates the evil method, as long as he has enough strength to control the evil power in this Netherworld Source Stone, he will definitely have a huge harvest.

"Fortunately, the strength of the Purgatory King is not enough, otherwise this Netherworld Source Stone would have been taken away by the Purgatory King long ago!" Lin Fang also felt that it was a fluke, the Purgatory King knew that his strength was not enough to refine this Netherworld Source Stone, and if he forcibly refined, he would only be eaten by it, and finally become an unconscious murderer.

Lin Fang's figure flashed, and he took the Netherworld Source Stone. As soon as the Netherworld Source Stone came into contact with Lin Fang, an evil aura quickly drilled towards Lin Fang's body. Fortunately, Lin Fang had already taken precautions, and the power in his body had already been activated, forcing all his breath out.

Lin Fang didn't have time to take a closer look, so he put it into a storage ring that didn't contain anything. This Netherworld Source Stone, if it is in one place for a long time, any item will be contaminated by the evil aura, and thus demonized.

The Netherworld Spring just now is actually the evil qi of the Netherworld Source Stone, which was finally formed after years of accumulation. Therefore, the Nether Spring generally cannot be too far away from the Nether Source Stone, otherwise it will automatically dissipate.

After collecting the Netherworld Source Stone, Lin Fang and the others searched for it in the dungeon again, but they never found anything. The group of four people was not in a hurry to leave here, but planned to accompany Fang Fengting, and only left here after Fang Fengting's injuries had fully recovered.

And Fang Fengting also understood everyone's thoughts, and wholeheartedly began to recover from her injuries with the help of Lin Fang and others. She knew very well that a long delay would not be a good thing for them.
