The whole crack of the earth is only one kilometer long and one hundred meters wide. If it was not Song Fei's luck, he would not easily feel that such a crack would be hidden under the fire cloud.

"You follow behind me and keep a twelve point alert." Song Fei warned again and again, feeling the breath that frightened his soul from the crack of the earth in the flame cloud.

At this moment, in addition to Song Fei himself, there are only five Yang people, including Yue Xiaxia, ziri and Yangxia mountain.

"Father, don't worry, I will protect myself." Yue Xiaxia squeezed her pink fist and expressed her determination very firmly.

The little beast has been raised by Jun wanshuang since childhood. He has dealt with fierce beasts since he was born in the original valley. I don't know how many times he has been chased by fierce beasts. Because of these experiences, Song Fei can rest assured that she will stay.

The group of people fell slowly, and the closer they were to the crack, the stronger the burning breath. As they fell completely under the horizon, Song Fei suddenly felt that the surrounding temperature had increased by at least three times, and the more downward, the higher the temperature.

They practiced the ultimate skill of fire. They were not afraid of the hot temperature, but became more comfortable in the fire.

At this moment, people have already been surrounded by flames, as if they were in a furnace. In addition, their divine knowledge is limited, and their visibility becomes very low.

"Follow me." Song Fei said in a deep voice. There was light in his eyes from time to time. Song Fei showed his thousands of miles' eyes and planned to see through the whole rift valley.

However, Song Fei was disappointed. Although Qianliyan played a level of more than ten times his eyesight, it also had a great impact in the rift valley. The hot flame had burned and distorted the light. Where he was more than ten times his sight, he could only see a piece of fiery red.

Therefore, several people did not dare to fly at high speed. After flying for more than ten minutes, they felt down-to-earth. They finally reached the bottom of the rift valley.

A long river of flames came from the depths of the earth and crossed the rift valley. I don't know where it extends.

The river is about 100 meters wide, as wide as the crack when it came in. The "water flow" flowing inside is actually the red flame of liquid.

In everyone's impression, the flame is a flame, and there will be no liquid flame, but at the moment, what breaks people's understanding takes place in front of people. Every drop of "water" here is composed of a burning flame, and the flame seems to be eternal and eternal.

Song Fei and others stood by the river and looked shocked at the flowing river. Yangxia mountain even couldn't help squatting down and picked up a handful of river water from the river.

A handful of red liquid flame slowly flowed in the palm of the hand, reflecting the red face of Yangxia mountain.

Soon, Yangxia mountain closed his eyes and silently realized it for a while. After a while, his face suddenly showed a thick surprise and said, "supreme, this is the immortal flame."

"I know, it's called immortal fire." Song Fei said faintly, "This fire will last forever. It's between water and fire. You can also see it as a kind of water. Although this immortal fire is an immortal flame, it has a wide range of uses. In addition, it is mild in nature. It is the most precious treasure of many flame friars. Even an Alchemist can improve the success rate after adding immortal fire. As for the actual effect, I don't know."

Song Fei once coveted all kinds of flames in the God level exchange system. This immortal flame was one of the flames Song Fei coveted, but he never thought that there was an immortal river flowing in this place.

Yangxia mountain was stunned and whispered, "water? So supreme, can it be used to cultivate the sun's true fire?"

"Naturally, it's a gentle flame that doesn't extinguish the sky fire. I'm afraid it's the most suitable flame for cultivating the sun's true fire among the earth fairy level flames. Originally, it's a little troublesome for you to refine the earth fairy level flame, but refining it without extinguishing the sky fire can be much smoother." Song Fei threw a small porcelain vase to yangxiashan and others, "Collect some as soon as possible. I feel a dangerous smell approaching."

Several people quickly nodded without Song Fei's warning. They also felt that there was a danger approaching, but they didn't know where the danger came from.

Everyone, including Song Fei, was holding a small porcelain vase. As mana poured into the small porcelain vase, a strong suction suddenly appeared at the mouth of the small porcelain vase. The immortal fire in the fire river was sucked up by distance and quickly poured into the small porcelain vase.

Feel more and more immortal fire in the small porcelain vase, and everyone's face is filled with thick surprises.

Every drop of this immortal fire is very rare, not to mention that it can now be sucked into small porcelain bottles. Song Fei roughly estimated that the amount of water sucked in in a second can be worth tens of thousands of immortal stones.

The speed of immortal stone is simply faster than picking it up.

Song Fei moved in his heart and immediately squatted down and put his hand into the flame river.

"Ding Dong, if you find that you can't extinguish the sky fire, you can exchange one trillion points. Do you want to exchange it?" unexpectedly, there are only one trillion points, which is equivalent to the amount of immortal sky fire inhaled every second?

Song Fei thought he could directly exchange the water in the long river of fire. Now it seems that he is wishful thinking.

However, a small porcelain vase can exchange 10000 immortal stones per second much faster than a small porcelain vase.

"Ding Dong, if you find that the sky fire cannot be extinguished, you can exchange one trillion points. Do you want to exchange it?" "exchange!"

"Ding Dong, if you find that the sky fire cannot be extinguished, you can exchange one trillion points. Do you want to exchange it?" "exchange!"

"Ding Dong, if you find that the sky fire cannot be extinguished, you can exchange one trillion points. Do you want to exchange it?" "exchange!"

"Exchange!"

"Exchange!"

"Exchange!"

..

In Song Fei's heart, he kept shouting for exchange. This frequency is much faster than the absorption of small porcelain bottles.

One trillion points, two trillion points. Before long, Song Fei had hundreds of trillion points, and it was increasing at a terrible speed.

"Daddy, something's wrong!" Yue Xiaxia suddenly pointed to the river and shouted.

Needless to say, Yue Xiaxia said that everyone had seen that "bubbles" appeared in the flame River, and the areas with bubbles kept rippling layer by layer.

"Supreme, there is something coming out below." Yangxia mountain eagerly said.

"It's a group of fish!" Song Fei's eyes flashed, and then his face changed slightly, "a lot of fish!"

Suddenly, from the red flame River, a fish creature the size of an ordinary crucian carp rushed out. In addition to having the shape of an ordinary fish, there were sharp spikes around their bodies with dark barbs. The fish's head is very big, occupying most of the body. The fish's mouth is open, revealing two rows of pure white teeth.
