Yun Lao paused and then spoke: "This spiritual fire is not simple, it's just behind that stone wall! I'll go and prepare it first, and I'll tell you what kind of spiritual fire it is later!"

Lin Feng was speechless for a while, why do you like to play dumb riddles? Wouldn't it be nice to say it clearly?

"If you break open that stone wall, you can see that spiritual fire!" Yun Lao said after a while.

Lin Feng followed what Yun Lao said, and punched towards the stone wall. "Why is it so hard!"

"Bang~Bang~" hit the stone wall with two more punches, and the stone wall cracked a crack in the middle, and the sand and stone kept falling.

"Bang~" "Boom~"

Lin Feng made up another punch, and the stone wall collapsed!

There was magma everywhere, and Lin Feng's eyes widened, feeling that this was an underground magma! In the middle of the magma, on a rock.

Lin Feng felt two strange energies, cold and fiery! Ice and fire can coexist? Lin Feng looked at the flickering flames! One side was dark blue, the other was fiery red, and it was constantly swaying on the rock!

"Master, what kind of spiritual fire is this? How can two mutually exclusive forces coexist as one?" Lin Feng finally opened his eyes today!

"What's impossible about this? It's just that your vision is too low, you haven't seen it, the world is full of wonders! This is the Netherworld Spiritual Fire! The Netherworld Spiritual Fire gathers the water spiritual power and fire spiritual power of the five elements of heaven and earth! It belongs to the mutated category of heaven and earth spiritual fire!" Yun Lao said slowly.

"Eh, what Five Elements Spiritual Power?" Lin Feng was confused when he heard it!

"Heaven and earth are divided into five elements, and the five elements play yin and yang, and yin and yang turn chaos! The foundation of heaven and earth spiritual energy is the spiritual power of the five elements, and the spiritual power of the five elements is divided into gold, wood, water, fire, and earth!" Yun Lao explained again.

Lin Feng is still confused, I don't know why!

"Forget it, I told you so much that you don't know, when your strength reaches that level in the future, you will naturally understand, now let's devour and refine this ghost fire first!"

"Brother Lin Feng, why are you in a daze?" Xia Mu saw Lin Feng stay where he was, his little hand shaking in front of Lin Feng's eyes.

"Well, I'm thinking about how to subdue this spiritual fire! This is the Netherworld Spiritual Fire, one of the spiritual fires of heaven and earth. The coexistence of two different forces is a bit troublesome to subdue!" Lin Feng explained.

"Well, this flame looks like a nuisance! It's in the middle of the lava, so it's hard to get close to. Why don't you forget it!Let's come back when the strength is strong!" Xia Mu frowned, not wanting Lin Feng to take risks.

"Don't worry, I won't come here if I'm not sure!" Lin Feng directly spread his light wings behind him, "You forgot, I still have wings!" As he spoke, the light wings shook, and Lin Feng slowly approached the rock in the center of the magma!

"Alright, just stop here!" Yun Lao reminded when he was still ten meters away from the rock. "Generally, the Heaven and Earth Spirit Fire will have a guardian spirit beast, I estimate that the guardian spirit beast is hidden under the magma, and I haven't sensed its existence yet!"

Lin Feng stopped in mid-air, vigilant in all directions, there is an unknown existence waiting for him, he must be careful!

"Lin Feng, it's coming! right under your feet, get ready!" Yun Lao suddenly reminded.

Lin Feng stared at his feet intently!

"Danger!Brother Lin Feng!" Xia Mu shouted.

Caught off guard, a pillar of fire shot from behind Lin Feng! Lin Feng broke out in a cold sweat, his wings shook, and he avoided the pillar of fire!

"Xiao Feng, you have to be careful! This guardian spirit beast has a lot of spiritual intelligence, and its cultivation is still at the level of a martial king. It's hiding under the lava, and you'd be hard-pressed to find it!"

Lin Feng used his spiritual sense, but the magma under his feet was full of fiery red, and he couldn't tell where the guardian spirit beast was. "How can you fight this? That guardian spirit beast is hiding under the magma, and it will give you a blow if it is cold!"

"Xiao Mu, you keep attacking under the magma, I'll go and subdue that spiritual fire!" Lin Feng suddenly thought that there was still a person at the level of a martial king like Xia Mu, his eyes lit up, and he thought about it.

"Okay, Brother Lin Feng. Xia Mu kept shooting ice arrows under the magma. However, the ice arrow melted as soon as it touched the lava.

Lin Feng was speechless, this little girl, there is really no way!

"Xiao Mu, don't you know any other moves?" "There is another trick, which is the hole card taught to me by the master, and it is said that it is easy to use!"

"Brother Lin Feng, be careful under your feet!" Another stream of magma shot towards Lin Feng!

"I'll go, what the hell is this, and I won't come out! As soon as Lin Feng finished speaking, dense magma shot towards him, and there was no hiding place at all!

"I'm scared to death baby!" In the blood coffin space, Lin Feng patted his chest and said. "Brother Lin Feng, are you okay?" Xia Mu opened his eyes wide to look around for Lin Feng, and just now Lin Feng suddenly disappeared!

One by one, the magma lost its target, and turned the spearhead to Xia Mu, and another burst of dense magma shot towards Xia Mu! In the blood coffin space, Lin Feng released his spiritual sense, and when he saw the situation in the outside world, he couldn't help but worry for a while, and was about to go out.

An ice shield appeared around Xia Mu's body, resisting the magma!

"Xiao Feng, it's a good opportunity, take advantage of the moment and receive that ghost spirit fire into the blood coffin space, then it won't be able to escape!" Yun Lao said to Lin Feng.

Lin Feng appeared directly, and the light wings behind him shook hard, and instantly appeared on the rock where the ghost fire was.

"Close!" Boss Yun shouted, and the ghost fire disappeared directly!

"Xiao Mu, you go and wait for me outside! Hurry up!" Lin Feng disappeared after speaking!

"Okay, Brother Lin Feng!" Xia Mu finished speaking and ran out the same way.

"Hiss~" In the underground magma, a roar came out, with an abnormal anger in the roar! The magma kept rolling, and the underground cavern was constantly eroded by the magma.

In the blood coffin space, Lin Feng stood beside the spirit pool and looked at the ghostly spiritual fires that were scattered everywhere. There was a burst of joy in his heart, but he had a great headache! The ghost spirit fire was strung around, and Lin Feng only felt that it was cold for a while and hot for a while, it was simply two heavens of ice and fire!

"Master, what should you do next?" Lin Feng looked at Yun Lao.

"The Spectral Flame hasn't fully grown yet, and now it only has a crippled consciousness. You have to go and devour it with the fire of chaos that you have obtained!Directly suppress it with soul coercion, and then wrap it in the fire of chaos, and retract it into the sea of consciousness to let the fire of chaos slowly refine itself!"

"Eh, Master, what is the soul coercion?"

"Soul coercion, wait a minute, you can take a good look!" After Yun Lao finished speaking, the whole person suddenly changed, and a momentum emanated, which made Lin Feng almost out of breath!

"Master, is this the coercion of the soul?

"Quick, now, summon your Chaos Fire!"

Lin Feng summoned the Chaos Fire from the Sea of Knowledge, and then controlled the Chaos Fire to envelop the motionless Netherworld Fire in that corner! Lin Feng wrapped the Netherworld Fire tightly, so he dared to take the Chaos Fire back into the Sea of Knowledge!

It's done! Lin Feng breathed a sigh of relief! If it weren't for the presence of Yun Lao, let alone refining the spiritual fire, it is estimated that he would be burned to ashes by the spiritual fire outside!

"Now all you have to do is wait for the Chaos Fire to swallow up the Nether Spirit Fire, then you will have the Chaos Fire with the special effect of the Nether Spirit Fire, and then the Nether Spirit Fire will no longer exist in this heaven and earth, and each Heaven and Earth Spirit Fire will only come out once in 10,000 years! By the way, you can solve the guardian spirit beast outside! Now it is in anger!"

Lin Feng stood in place, and suddenly, a small head appeared in the spirit pool!Hmph~ A small beast appeared directly on Lin Feng's shoulder.

"Xiaobai, you're awake!I miss you!" Lin Feng hugged Xiaobai for a kiss! Lin Feng was so bored when he was cultivating, he used to have Xiaobai by his side when he was cultivating, accompanying him!

On Xiaobai's face, he made a very humane expression of contempt for Lin Feng! Yes, it is contempt!

Lin Feng was stunned, when will Xiaobai be so humane? and still despise himself!"Xiaobai, when did you learn to despise people?"

"Xiao Fengfeng, this divine beast has always been!" the little white milk voice made a milky sound.

"I'll go!" Lin Feng almost threw Xiaobai out!, "When will you be able to speak?"

"It's all said, I'm a great divine beast!" Xiao Bai said with a look of anger.

"Rub, you shameless Xiaobai, you still have a divine beast, tell me, what kind of divine beast are you?" Lin Feng was a little puzzled about what kind of divine beast descendant Xiaobai was!

"I'm a descendant of the Ancient Heavenly Winged Divine Tiger, the only one!

"Tianyi Divine Tiger, haven't you heard of it? It can't be that you made it up, right? I think you're just a little tiger!" Lin Feng looked at Xiao Bai with disdain!

"Xiao Fengfeng, you still don't believe it! The level of this divine beast is now higher than yours, have you ever beaten this divine beast?" Xiao Bai directly exuded the coercion of the Martial King level.

"Yohe, you have the ability now, right? Your wings are hard, aren't they?" Lin Feng grabbed Xiaobai's tail and hung it upside down in mid-air.

Xiaobai's four claws kept scratching, but he couldn't catch Lin Feng. "Xiao Fengfeng, hurry up and let go of this divine beast, it's not good for you to abuse this divine beast like this, let it go!"

"Your uncle, I saved you in the first place, and besides, this is my territory! Don't forget where you are! By the way, call me big brother, don't call me Xiao Fengfeng! I'm your big brother!" Lin Feng corrected.

"Little Fengfeng," "Huh, big brother!"

"Just scream, hum! Wait!" "Big brother, let go of me!" Xiao Bai's two little front paws were put together, very funny! Lin Feng was amused, and as soon as he let go of his hand, Xiao Bai fell directly to the ground!

"Ah, Xiao Fengfeng, tell you to pull the tail of this divine beast! I'll kill you!" Xiao Bai shouted, scratching around Lin Feng!

"Don't make a fuss, there is still business to do now!" Lin Feng grabbed Xiaobai and got out of the blood coffin space!

"What kind of place is this, there are so many magma!" Xiao Bai stood on Lin Feng's shoulder, his two big eyes full of curiosity!

"This is underground!" "Hehe, I'll go down and take a shower first!"

"Be careful!" Lin Feng was about to act, but he saw Xiaobai scurrying in the magma! A hanging heart suddenly let go!

"It's not good, Xiaobai, let's go, that guardian spirit beast is out!" Lin Feng's face changed, and he shouted at Xiaobai!
