"There is actually a fire vein in the center of the earth here, why didn't you sense it before?"

When Lian Tianhuan heard Cheng Qian's surprise, he put away his smile and said with a stern face.

"Okay, it's just the fire vein in the center of the earth, don't make any fuss!"

Lian Tianjie cut her hair, and her interest was greatly lost. It's no wonder that the two of them have been in this underground space for hundreds of years, so much so that they have a great interest in anything.

Seeing that her sister had lost interest, Lian Tianhuan was also speechless, took her sister's hand, and returned to her stone house.

Cheng Qian looked at the backs of the two of them leaving thoughtfully, and when the figures of the two completely disappeared from sight, Cheng Qian withdrew his gaze, and his figure flickered directly to the edge of the pillar of fire.

Looking at the pillar of flame in front of him, Cheng Qian suddenly stretched out his palm and pointed at the void. Immediately, a small line of fire split out of the pillar and swirled in the palm of his hand to form a fireball.

Shen Nian swept up on it, and his brows furrowed: "It turned out to be the vein of Yin Fire, this is an excellent flame for refining the Soul Treasure!"

Everything in heaven and earth is divided into yin and yang, and those earth-centered fire veins found in the human world are pure yang fire, necessary for refining magic weapons and treasures.

The underworld here is different, although it is similar to the ordinary Earth Core Fire Vein God, but it is very different.

In this small group of flames, although it had an extremely terrifying high temperature, it could still be seen that there was a faint yin qi diffusing from it, which could be described as two heavens of ice and fire.

"This thing is good, it's a pity to waste it!"

As soon as Cheng Qian grasped his five fingers, the fireball in his palm immediately disappeared, and then the mana in his body was urged, and a sinking three-color flame ignited on the surface of his body, and the temperature around him dropped sharply.

"Go!"

He pinched his hands for a trick. The three-color cold flame on the surface of the body immediately rose sharply, and it turned into a three-color firebird with a tumbling down.

As soon as the firebird spreads its wings, it soars into the air. Hovering around the pillar of flames, as if looking at something.

The Zhanjing Extreme Fire cultivated by Cheng Qian had not absorbed new flames for a long time. And this yin-attribute earth-centered fire vein is a great complement to the cold flame of Zhanjing Extreme Fire.

Since he met Cheng Qian, he naturally would not be violent with heavenly things, his hands flew like butterflies wearing flowers, and after the tricks were played.

"Gah!"

Suddenly, the three-color firebird let out a high-pitched scream, and after circling around the pillar of fire for a week, it immediately opened its mouth at the pillar of flame and sucked it up.

I saw the pillar of flames that went straight to the sky, as if it had been pulled by something. It began to twist and turn, but immediately dozens of thin lines of flame dispersed, and were sucked into the belly by the three-color firebird.

Half an hour passed like this, and the color of the crystal extreme fire, which originally exuded a strange cold power, became darker, and in addition to the power of the strange cold, it gradually began to exude a creepy aura.

Cheng Qian silently watched the changes in Zhanjing's extreme fire, and there was no discoloration on his face.

As time passed, the power of the flames that spewed out from the pillar of flames that soared straight into the sky gradually weakened. It was as if it was going to disappear in the next moment.

Witnessing this scene, Cheng Qian suddenly had a bold idea, and he was covered in mana. The flame power of the fire spirit bead in the body immediately gushed out, and the body was immediately enveloped.

The next moment, Cheng Qian's sleeves rolled up, and the whole person turned into a rolling high-temperature fireball and went straight to the pillar of flames.

The three-color firebird, which was greedily devouring the Yin Fire, seemed to have received some order, and its whole body suddenly exploded, turning into pieces of broken small flames, and rolling towards the fireball in the sky.

Then the fireball spun around, carrying a three-color cold flame like a meteorite falling to the ground. Crashed down and went straight to the big hole that had been opened before.

"Boom!"

With a muffled sound, a pillar of flame that soared straight into the sky. Immediately, the flag died down, and the three-color fireball disappeared into the crater.

Meanwhile. Cheng Qian turned into flames at an incredible speed and shuttled wildly underground, but in the blink of an eye, his body was already hundreds of feet deep underground.

The further down he went, the more frightened Cheng Qian became, he didn't expect that the pit that he had blasted out by casting the Nine Heavens Divine Thunder was so deep, no wonder it took half a day for these ground sparks to reach the ground.

On the ground, the Lian sisters suddenly flew out of the cave, and with their cultivation, they naturally clearly saw Cheng Qian escaping into the hole.

The two of them came to the edge of the pit in a flash, and glanced at it suspiciously, although the pit was still emitting a high temperature that distorted the air, there was no trace of flame in sight.

And this pit is bottomless, even Cheng Qian's figure is gone, and only a faint light can be seen from the ground.

"Senior brother, what's crazy, why do you have to go down now?" Lian Tianhuan and her sister looked at each other, not understanding what Cheng Qian was doing at all.

"How do I know that the temperature of this earth's core fire vein is extremely high, even if it is the two of me who are in the transformation period, they may not be able to be intact in this high temperature!"

"He should have his own grasp in doing this, he should be cultivating some kind of fire technique!" Lian Tianhuan sighed, said leisurely, and at the same time slapped his palm, and a small black fruit appeared in his hand, and when he bit into it, the fruity aroma was juicy and crunchy.

Lian Tianjie looked at her sister with a stunned expression, pointed at her and said, "No wonder I found that your divine sense has become so pure, I didn't expect you to eat this fruit as a meal." ”

"Uh, what's there?" said Lian Tianhuan as he chewed on the flesh of the fruit.

"You're going to have a big incident, Master said that although this fruit is a good thing, you can't eat too much, be careful that your consciousness is solidified and you can't release it!" Seeing this, Lian Tianjie was a little angry, and said angrily.

I snatched the black fruit that only half of the bite was left, and took a look.

"What are you doing! What's the big deal, isn't it okay now? Give it back to me!"

The elder sister snatched her fruit, and the younger sister was furious and wanted to snatch it back.

"No, Master said you can't eat too much!"

"I really thought you were my sister, so I was afraid of you, give it back to me!"

"You have the ability to take it yourself!"

In this way, the two of them came and went, hugged each other directly, and fought unceremoniously for half of the fruit.

The two women are like wolves. I don't pay attention to the slightest image at all, you punch, I slap. It's a lot of fun!

......

In the blink of an eye, three days later.

The Lian sisters stood in the big courtyard of the valley with blue noses and swollen faces. It seems that something is waiting for.

The two glared at each other, as if they had a great hatred.

At this time, a blue rainbow suddenly broke through the void, and after a few flashes, it landed in the compound.

After the blue light faded, Shi Fengchun's figure appeared.

"Master!"

Seeing that the old guy was coming, the two girls didn't dare to make a mistake, so they hurriedly saluted.

"Hmm. What's wrong with you?" Shi Fengchun was stunned when he saw the two of them with blue noses and swollen faces, and he didn't know what he had missed.

However, I already knew in my heart that these two sisters, in the past few hundred years, fights and brawls have been common.

remembered that when the two of them had blue noses and swollen faces for the first time, Shi Fengchun didn't know what the reason was, and he immediately became furious, thinking that it was the corpse king's person who didn't give him face and bullied him in vain. The result can be imagined, and he directly went to the territory of the three corpse kings to make a big fuss.

"Humph!"

Hearing this, Lian Tianhuan snorted and did not answer Master's question.

But Lian Tianjie smiled bitterly. A little aggrieved: "My sister is disobedient and eats a lot of Void Yin Fruit, but Master said that you can't eat too much of this thing." ”

"You also said that I obviously didn't eat a lot!" When Lian Tianhuan heard this, he was immediately unhappy, what did he call me disobedient, and suddenly jumped out.

The two rolled up their sleeves and began to chatter and quarrel again, Shi Fengchun had a headache when he saw it, and the two apprentices didn't know where to learn the character. Extremely eccentric.

Even the old guy himself couldn't see through it.

"What about Cheng Qian?"

When the two of them quarreled, they didn't know if they would fight again. Shi Fengchun immediately snorted coldly and asked.

The sound exploded in the ears of the two sisters like thunder. The two of them immediately became honest and looked at the old guy in horror.

It's not fun for this old guy to get angry, but they've seen Master get angry with their own eyes, and it's going to be a river of blood.

"Inside that hole, it hasn't come out yet!"

Lian Tianhuan didn't look at her sister, and directly pointed to the pit in the distance and said.

Shi Fengchun was stunned for a moment, hurriedly walked over and took a look, and seemed to see something in the doorway, and said to the two sisters, "Are you ready?"

"The apprentice is ready, and he can leave at any time!"

The two women spoke one after another.

"Okay, then wait!" Seeing this, Shi Fengchun didn't say anything, but sat down cross-legged directly next to the pit, as if waiting for Cheng Qian.

......

At the same time, at a depth of 7,000 zhang, large swaths of magma flowed underground.

And Cheng Qian is like a fish of flames, shuttling and frolicking in the magma like a fish in water.

Sometimes he emerges from the lava, and sometimes he dives into the lava.

If you look so closely, you can find that Cheng Qian's whole body exudes a terrifying cold aura at this moment.

After half a cup of tea, a strange scene appeared.

Bursts of white smoke suddenly rose from the surface of the entire flowing magma, and after a while, there was a continuous 'click' sound.

I saw that the magma was freezing at an incredible speed, and pieces of crimson ice floe were condensed on the surface of the magma.

"Seal!"

The next moment, Cheng Qian suddenly broke through the ice, and his figure flew over the magma in a flash, and his palms pressed down, and suddenly a strange cold force erupted from his palm.

Suddenly, a layer of frost enveloped the area. It didn't take long for the entire flame stream to be solidified by a layer of hoarfrost, and it was completely frozen for thousands of miles.

"The Yin Fire Essence Gold in this place has been absorbed by me, even if I don't freeze the magma, this core fire vein will gradually evaporate and disappear, in this way, it can be regarded as preserving this fire vein, and I hope that it will re-derive new Yin Fire Essence Gold after thousands of years!"
