This underground river is nearly a hundred feet wide, and the water flow is not very turbulent, but looking at the river water, it looks extremely deep, and there are large clusters of underground magma floating inside.

The river water rustled, and in places with large magma, there were still turbulent mist.

"This place is actually full of lunar attributes and yang attributes, and the energy of the two systems seems to surge from here and overflow into the hot spring mountains."

Sister Gu was also very cautious. She took Xiao Lingyu and Ling'er downstream and said, "The two energy systems are obviously coming up from the downstream, and the two strange fire spirits have also run downstream."

"In addition to the abnormal energy fluctuations of the two systems of Yueyang, I feel that there is also an obviously very powerful abnormal energy fluctuation downstream. There may be dangers ahead, so why don't I go to explore the way forward first." Ling'er said.

"Okay, you have to be careful. If something is wrong, turn around immediately." Sister Gu nodded.

Ling'er accelerated forward and concealed her figure at the same time.

Half an hour passed, Ling'er came back. After revealing her figure, she frowned and said, "There is no danger ahead, but the scene looks terrifying."

Under Ling'er's leadership, everyone accelerated their speed and walked along the underground river.

Not long after, everyone arrived at the abyss.

The abyss is the end of the dark river. The dark river continues to move forward, and the flow goes down, forming a waterfall with a roaring sound of water.

When you are on the bank at the end of the river and look down at the abyss, you can see that the abyss is only a thousand feet high, and at the bottom of the abyss is a surging river of magma.

Looking down from a high place, the entire magma river is like a fiery red dragon.

After a closer look, Xiao Lingyu and Sister Gu both felt numb in their scalp. In this section of the magma river, there was a huge body lying across.

The corpse was human-shaped, but it was more than a thousand feet long and nearly three hundred feet wide. It was wrapped in a black iron armor that looked like it was already ragged, and it was stuck in the magma river channel, with white and black light all over its body.

And the black and white fire spirit was hovering on the body of the thousand-foot giant corpse, looking reluctant to leave.

Monsters with great strength emerged from time to time from time to time from the magma river. They opened their bloody mouths to eat the corpse, but they bit them down in one bite. Not to mention tearing off a piece of flesh and blood, even if they could not even hurt the corpse.

The black and white fire spirit kept surrounding the giant corpse, and drove out the monsters in the magma river.

No wonder Ling'er said that the scene here is a bit terrifying.

"I guess he was an extremely powerful man during his lifetime." Sister Gu said.

"The black and white fire spirit should be the true fire he had during his lifetime. Because the year and month of his death were too long, the power of the true fire was reduced too much." Xiao Lingyu continued.

"No wonder the fire spirit is so fast, and the power that burst out in the moment of fusion is terrifying." Ling'er nodded and said.

"What should we do?" Xiao Lingyu asked.

"You can take the relics away, so let his body be left here." Sister Gu said calmly.

Xiao Lingyu knew that Sister Gu did not want to touch the body itself, and she respected the strong and the dead.

"The fire spirit will definitely not escape again."

As Ling'er said, she jumped to the bottom of the abyss and hid in halfway.

When Ling'er appeared again, she had reached the bottom of the abyss. The boundless nebula and mist suddenly spread out, instantly covering the river section where the corpse was located.

The black and white fire spirit was anxious. Although it rushed out of the nebula again and again, it rushed in without hesitation.

"Let's go down too."

After saying that, Sister Gu also fell down.

Xiao Lingyu followed Sister Gu closely, and after a while, the two of them also came to the nebula.

With the cover of the nebula and mist, Xiao Lingyu and the other two continued to attack the black and white fire spirit.

The Black and White Fire Spirit was obviously too anxious. It kept rushing in the nebula and mist. Unfortunately, under Ling'er's intentional control, the thick nebula and mist kept rushing towards its body, causing it to completely lose its direction and unable to see the target clearly. It could only rush around and crash, unable to cause any damage.

After continuing to attack for a while, Sister Gu took out special materials and began to arrange formations around her, while Xiao Lingyu cooperated to form a series of prohibitions.

Just a hundred breaths passed, Sister Gu and Xiao Lingyu jointly set up an extremely powerful forbidden array. With Ling'er's nether clouds and mist cooperation, the black and white fire spirit was not only blocked, but also had a smaller range of movement.

After the forbidden formation began to show its power, Sister Gu came to one of the palms of the huge corpse and said calmly: "His storage ring is still there."

There is a ring on the ring finger of this palm. The ring is simple and simple in shape, and it should be a very high-quality storage magic weapon.

Xiao Lingyu did not move, while Sister Gu released her skills and soul power to surge towards the ring.

The finger ring then released a stream of energy with a little starlight, wrapping up Sister Gu. After only twenty breaths, the finger ring suddenly trembled, automatically fell off the ring finger of the big palm, and flew into Sister Gu's finger.

The storage magic weapon has been obtained, and the rest is naturally to fight the black and white fire spirit with all its strength.

The black and white fire spirit was trapped by the forbidden formation. Sister Gu frowned and said, "This fire spirit is a fusion of two true fires, which is only suitable for you. Only you can refine it among us."

"Fortunately it is a fire spirit rather than a real real fire, otherwise this real fire alone can easily kill us."

Xiao Lingyu nodded and then said, "Let it sleep for a while, and when it becomes desperate and gentle, it should be much easier to refine it."

Sister Gu did not raise any objections. The three of them continued to cast spells to block and attack the black and white fire spirit. Sister Gu began to check the collection in the storage ring at the same time.

“These stones should work for you.”

Sister Gu brought a storage bag to Xiao Lingyu. Xiao Lingyu sank his divine thoughts into it and looked at it, and his face was stunned.

"These are chaos rough stones!" Xiao Lingyu said in surprise.

In that storage bag, there are countless gray stones, which contain a very thick Chaos Force.

"It's the Chaos Heavenly Crystal." Sister Gu corrected.

"It is indeed useful to me, but there are so many Chaos Heavenly Crystals, which is enough to prove that this strong man was a Chaos Cultivator like me during his lifetime." Xiao Lingyu said calmly.

"Haha, this doesn't matter. What's important is that these Chaos Heavenly Crystals are really useful to you."

Sister Gu smiled and said, "He has a lot of collections, but there are no finished products, only many high-quality materials, one of which is one of the important materials I lack when refining the Star Dome Pill. In this way, among the materials needed to refine the Star Dome Pill, there is only one rare thing that has not been obtained yet."

All Sister Gu needed was the material to refine the Star Dome Pill, so she then transferred most of the materials in the storage ring to Xiao Lingyu.

As for the ring, although it is obviously of high-grade grade, it is just a storage magic weapon. Everyone is not short of storage magic weapons, so Sister Gu did not give it to Xiao Lingyu.

Xiao Lingyu then checked the materials one by one, but did not find anything he needed very much.

More than a month passed, and the black and white fire spirits trapped by the seal seemed very weak, and were already suspended in the forbidden formation and motionless.

"The time has arrived!"

Xiao Lingyu released his Chaos Nirvana True Fire and wrapped it with the black and white fire spirit. His essence, blood, spirit and chaotic force also continued to penetrate into the forbidden formation and began to continue to sacrifice and refine the fire spirit.
Chapter completed!
