"I'm sure!" Kurohime affirmed.

Lu Fan frowned, Hei Ji's affirmative tone would not be fake.

However, there is no passage here, how can it go down?

After thinking for a moment, Lu Fan took out two harpoons from the dragon scale ring, which were the two keys that opened the undersea Dragon Palace.

These two keys made of unknown materials are extremely sharp, just enough to be used as chisels.

So, the two of them began to do manual work.

This can't help but make Lu Fan regret a little, he didn't bring the crab big, and he is an expert in this area.

In this hot cave, Lu Fan looked at Hei Ji's soaked and close-fitting clothes, which also made this boring project a little fun.

Fortunately, the two of them were not ordinary people, they were probably busy for more than half an hour, and when a stone was chiseled and fell down directly, Lu Fan was shocked and knew that he should be in the place.

But before he could rejoice, a wave of heat came up from below.

"Fertile grass!"

Lu Fan screamed, and quickly pulled Hei Ji out of the cave and escaped.

The temperature below is too high for the two of them to withstand at all!

"Kurohime, you go to the entrance of the cave first, it's cooler there. Lu Fan said to Hei Ji.

The temperature at the bottom has come up along the entrance of the cave, and even this stone cave can't stay.

"Good!"

Kurohime herself is a monster in the water, and fire is her nemesis.

After Hei Ji walked out, Lu Fan's heart moved, and the black spirit battle armor covered his whole body, revealing only two eyes.

In order to prevent accidents, Lu Fan directly took a harpoon and jumped down the hole dug out.

After landing, Lu Fan took a look, this is also a passage, and the exit at one end is actually a volcanic crater.

"Grass! ”

Lu Fan complained and walked to the other end of the passage.

Although the temperature was very high, with the black spirit battle armor body, Lu Fan felt a little cool.

"It deserves to be a treasure. Lu Fan couldn't help but appreciate.

At the end of the passage was a stone door, but there was no mechanism, and Lu Fan pushed it open with a force.

"Crunch!"

Suddenly, an even more terrifying heat wave hit, and the black spirit armor was a little hot.

Lu Fan raised his eyes and saw that it was a stone room, and the air inside was distorted.

In the middle of a cracked flaming red crystal floated a small golden flame.

"It's ......"

Lu Fan's breathing was a little short, and his eyes stared at the flame without blinking.

He could feel the good energy contained in the flames, and if it was released, he was afraid that this stone chamber would melt immediately.

Lu Fan hurriedly searched in his memory, and the Heavenly Dragon Treasure Book had a detailed description of the five elements of heaven and earth.

Soon found the same name as the description of the flame in front of me:

The Earth's Core Fire, born from the underground magma, is the essence of the highest temperature magma.

"That's not right!"

Lu Fan was surprised, feeling that the temperature description of this flame was a little different from that of the Earth's Core Fire, and it was obviously much lower.

Glancing at the piece of fire spirit crystal under the flames, Lu Fan suddenly realized:

"It turned out that the energy was running out. ”

The cracked hedron below was a fire spirit crystal, which was supposed to provide it with energy, and it had run out of energy in the endless years.

"It's better this way!" Lu Fan chuckled.

If it was the geocentric fire in its heyday, Lu Fan would have to turn around and leave even if he saw it, because it was not something that he could touch in this realm, and if he went to refine, it was estimated that there would be no slag left to be burned.

After filtering the method of refining the spiritual fire in his mind, Lu Fan tried to wrap the flame with dragon qi.

To his surprise, the whole process went unusually smoothly, and the flames did not resist at all.

"Doesn't it mean that these heaven and earth spiritual fires have a trace of spiritual intelligence, does it also want to leave here?" Lu Fan was stunned.

Take this flame directly back to the stone chamber above.

A formation was arranged at the entrance of the cave to prevent the real Dharma Protector from coming in suddenly, and asked Kurohime to stay outside to help him protect the Dharma.

After arranging everything, Lu Fan turned into a ten-meter-long blue true dragon and swallowed the Earth's Heart Fire in one gulp.

……

Magic City.

The most prosperous city in China is the economic center of the country.

Towering inside the building.

An old man with gray hair said respectfully to a man in his forties and fifties:

"Chairman, did you read the advertisement for the beauty mask a few days ago?"

The man, who was known as the chairman, glanced at the old man in surprise and said:

"The effect of this beauty mask is really good, it seems to have sold crazy in China, and it is said that it was developed by a master in the field of traditional Chinese medicine. ”

The old man shook his head and said, "I'm not talking about the mask, I'm talking about its boss." ”

"What's wrong with its boss, did they find you and want to cooperate with us?" said the chairman unexpectedly.

His family's business covers all fields of the magic capital, it is a wealthy family of hundreds of billions, and there is a martial arts master in charge, and there is an endless stream of people who come to seek cooperation every day, if someone does not stop it, I am afraid that the threshold will be broken.

The old man smiled and continued to shake his head, then took out a tablet from behind him.

found a video, clicked on it, handed it to the man, and said, "You take a look at what you're talking about first." ”

The chairman took it in surprise, watched the video for a while, and his eyes widened:

"It's ......"

"Does it look like it?" the old man asked the chairman with a smile.

"The face is similar, but more beautiful than her, more temperamental. The chairman seemed to be stuck in a long memory.

It was next to Qingshan Lake, a young girl in a white dress......

After a long time, the old man said, "She is also in Ninghai." ”

The chairman was shocked and said excitedly: "Have you confirmed it?"

"Not yet, you also know Madame's temper, if you do, I'm afraid it will be upset again. The old man was embarrassed.

The chairman put his hand on his forehead and said with a headache: "You try to send a trustworthy person to confirm." ”

"Okay! I'll do it. ”

The old man said with a sigh. This chairman seems to be beautiful, but he can't be the master in many things.

After the old man left, the chairman walked to the window and muttered, "Are you really my daughter?"

……

In a flash, a month has passed.

On this day, the bored Kurohime was leaning against the stone wall of the cave, playing the most popular chicken game on her mobile phone.

Suddenly, a golden flame rose from the blue dragon, which had been silent for a month, and the air in the cave crackled.

After a while, the color of the blue dragon's body began to change, slowly turning purple, and the dragon's body began to elongate, until it reached twenty meters before stopping.

The dragon's eyes, which had been closed for a month, slowly opened their eyes, shooting out two fine lightning rays, and the dragon's head was raised, spewing out a raging flame at the entrance of the cave.

"Boom!"

There was a roar at the mouth of the cave, and the rocks collapsed and burned to a pulp, rolling down into the crater and disappearing.

"Ahh

Kurohime, who was playing in a trance, was startled and looked up to see this scene.
