The mountain peak is very high, but it climbs very quickly at the speed of everyone, and none of those who can survive until now are weak, as they continue to rise, the temperature becomes lower and lower, and gradually there is hoarfrost all around, and everyone doesn't care, they haven't paid attention to the little change in temperature, only Lin Tianluo is vigilant in his heart, along the way, too many people have died, and this secret realm is definitely not a good place.

Sure enough, what are you afraid of, as you climb higher and higher, the temperature is dropping at a straight line speed, and in the end, even if they are cultivators, they also feel a chill, and they have run demon yuan to fight, this mountain peak they have climbed at least a few thousand meters, but when they look up, they are still not high.

I don't know how tall it is. Everyone muttered secretly in their hearts, but the city lord of Cloud City did not stop advancing, they could only grit their teeth to keep up, as time passed, they could no longer see the vegetation, the surroundings were full of ice, and the temperature had dropped to the extreme, even if there was a demon yuan resistance, they still couldn't make ends meet.

Just when everyone was about to hold on, the voice of the Cloud City City Lord came, "It's here." ”

Everyone looked up, sure enough, the top of the mountain was in front, the distance was not far away, everyone hurriedly cheered up, and after a while, they finally went to the top of the mountain, and the top of the mountain turned out to be a very large platform, all made of ice, standing on this huge platform, the individual has become very small. There is an altar in the center of this platform, and a stone ball is floating there on the altar, and the city lord of Cloud City takes the lead, and all the people come to the edge of the altar. In addition to the stone balls floating directly above it, there are pillars around the altar in a circle, leaving only a path to the top of the altar.

"This is a stone ball?"

Lin Tianluo touched the stone ball on his chest through his clothes, and felt very incredible, there was an identical stone ball suspended there, "Could it be that this is the core of the secret realm?"

With doubts, his face was silent.

At this time, the city lord of Cloud City spoke, and I saw him say loudly: "The stone ball on the altar is the core of the secret realm, I need you to inject the demon yuan into the surrounding pillars to help me activate the stone ball and refine the core." After speaking, the Cloud City City Lord directly ascended to the altar and sat cross-legged under the stone ball.

Everyone was very interested in choosing a pillar to sit cross-legged, surrounding the altar like the stars holding the moon, Lin Tianluo also chose a pillar to sit cross-legged, and the Cloud City City Lord, who was surrounded in the center, said loudly: "Begin." ”

With an order, everyone ran the demon yuan into the pillar, and with the injection of the demon yuan, the pillar gradually emitted various colors of light, and the light became thicker and thicker, and finally rushed towards the stone ball in the center of the altar.

Seeing this scene, the city lord of Cloud City nodded slightly, and then also ran the demon yuan, wrapped the stone ball, and silently refined the stone ball.

With the refining, the stone ball was slowly cracking, no, it should be a layer of stone shell on the outside that was slowly falling off, revealing a crystal clear bead inside.

Lin Tianluo secretly looked at the stone ball in his arms, and found that the stone ball in his arms was also slowly falling off, the same as the stone ball on the altar, I don't know if this change is good or bad, but he didn't dare to make the slightest move, if the city lord of Cloud City found that he still had a stone ball here, it was estimated that he would not be able to eat it and walk around.

As the stone shell fell off, the beads inside became more and more dazzling, and it was about to be completely peeled off, when the mutation suddenly happened, and I saw two people suddenly rushing from far away, and they came to the edge of the altar in an instant, and without saying a word, they shot directly at the cloud city lord in the center of the altar. The surging demon yuan surged out, and the city lord of Cloud City sensed the danger, but he couldn't make a move to fight it at the critical moment of refining.

The demon yuan came in an instant, and directly hit the city lord of Cloud City, the city lord of Cloud City's body trembled, and a stream of blood went straight to his throat, but it was swallowed back hard, and the two people saw that the city lord of Cloud City had resisted the attack, their faces changed, and then they pounced without hesitation, ready to attack again.

Seeing this, the city lord of Yuncheng jumped with his eyelids, he had already been injured by resisting two palms just now, if he let these two people pounce again, it would be difficult for the perineum to capsize, at this time, he couldn't care about refining the stone ball, and hurriedly put away his hand to seal it, and the demon yuan came out in an instant, spreading out in a circle, and the two people who pounced instantly collided on the circular enchantment, and then were knocked out at a faster speed, and took many steps back before barely standing firm.
