Iron Wings finally let out a long breath and sighed:

"That's it, if you don't succeed, you will become benevolent, and we will gamble. ”

Tie Yizi also took out ten fire source stones from his arms and handed them to Zhou Lu, driven by these two people, the others hesitated, and finally including the hedgehog head, all handed the fire source stones to Zhou Lu, and the form forced them to such a situation, they couldn't help but fight against the water.

After everyone had finished their discussion, Tie Yizi went out to find someone to study the energy source of the Black Ice Crossbow, and the bearded old man and Lian Lao Wu followed Zhou Lu curiously, wanting to see how he studied Thunderbolt.

Zhou Lu took the two out of the cave and went straight to the cold qi wall in the distance.

The turquoise cold mass is like a big wall standing on the top of the sky, the cold is condensed but not dispersed, like a substance, and the temperature outside the cold mass is dozens of degrees lower than elsewhere.

Zhou Lu walked to a distance of dozens of feet from the cold group and stood still, these colds were like the warm night breeze blowing through in late spring for him, except for a faint coolness, there was no other feeling.

However, the bearded old man and Lian Lao Wu in the back were frozen miserably, the two of them tightened their animal skin robes, their faces were blue and tight, and their upper and lower teeth kept chattering, they really didn't know what Zhou Lu wanted to come here to suffer this crime.

Zhou Lu's mind moved slightly, and the elemental power between heaven and earth turned into a large lilac hand, like a copper spoon pierced into jelly, and the lilac big hand reached into the cold demon mass out of thin air, grabbing a turquoise cold energy.

The large lilac hand retracted again, and the chilling energy twisted and struggled in the big hand like a living thing.

The bearded old man and even the fifth child were stunned.

The two of them stared at the miracle staged by Zhou Lu with wide eyes, and at the same time gasped.

The bearded old man put his beard around his neck as a scarf to keep out the cold, and he glared at him and muttered incredulously:

"There is something that can enter the cold and not be frozen, and it can also catch a cloud of cold, my God, my eyes are not flowered, how is this possible?"

In the concept of the bearded old man, anything, including any energy, will immediately freeze into countless particles and collapse when it enters the cold group.

Even Lao Wu's eyes suddenly lit up, and he was stimulated by one of his own thoughts, and he ran over in ecstasy, and shouted out breathlessly:

"Baby, baby, Zhou Lu, you can catch some of this kind of baby for me, I have a jade bottle here, you help me catch a cold demon and hold it up, in the future, out of the black ice field, I will refine this cold demon into a magic weapon, how good it is"

Lian Lao Wu took out a jade bottle in his arms and stretched it forward.

The bearded old man's heart was pounding.

If it is really feasible, then a cloud of cold evil is indeed an incomparable wonderful material for refining magic weapons, and if a cloud of cold evil is collected, then they will send it.

Zhou Lu smiled, waved his hand in the air, and the lilac energy big hand grabbed the cold and poured it into Lian Lao Wu's jade bottle, Lian Lao Wu slammed the cap of the jade bottle tightly, and laughed with joy holding the jade bottle.

At this moment, there was a bang, and the jade bottle suddenly burst into flames, and the cold inside twisted and writhed hard, flying towards Lian Lao Wu like a small blue snake.

Even Lao Wu's frightened whole body was upside down, and he jumped out in a flash and hugged his head, and the cold writhing in the void like a psychic, chasing after him like a blue light.

"Help. ”

Even the old five screamed hoarsely.

The bearded old man was surprised and amused when he looked at it from behind, it turned out that it was so dangerous to collect cold, and it turned out that this kind of treasure was not something that anyone could touch.

Zhou Lu waved out that lilac big hand, volleyed into the void, and grabbed the chill writhing in the air again, Lian Lao Wu looked at the thing in Zhou Lu's hand, and was frightened and retreated, he didn't dare to covet that kind of thing anymore.

Even the strange screams of the fifth child alarmed the others, and the tiger and the hedgehog head also ran over to this side, and when they saw that there was nothing wrong, the tiger ben let out a long breath, and the two of them also endured the cold and stood beside them, curiously watching how Zhou Lu behaved.

Zhou Lu used his divine thoughts to extract the heat energy in the hundred fire source stones at the same time, and turned into a small fiery red snake, the fiery red little snake chased after the turquoise snake that was transformed into a cold and blue snake, and under Zhou Lu's divine thoughts, the two beams of light spun faster and faster, turning into a blue-red light in the air.

The four in the distance watched dumbfounded.

They didn't know that at this time, Zhou Lu was actually running extremely hard, the power of cold and evil was really difficult to control, if you want to achieve a delicate balance between this kind of cold and heat energy, it is tantamount to a thousand shots, Zhou Lu found that something was wrong as soon as he got started, it was too difficult to control, it was countless times more difficult than he expected, Zhou Lu was a powerful realm of the lower gods, so he could control these two light clusters without collapsing.

If it was a bearded old man who had just entered the realm of the Xuan level, I am afraid that in an instant, those two rays of light would explode.

Zhou Lu forcibly controlled the two light clusters more and more condensed, and the volume became smaller and smaller.

The smaller the size of the light cluster, the more you can feel the incredible explosive energy contained in it.

The four bearded old men opened their mouths widely, and they were dumbfounded when they looked at this scene, and even the fifth man muttered to himself:

"It's done, it's almost done, I guess Zhou Lu is about to succeed, you see, the light has reached the size of a fist, and if it shrinks a few more times, it will be about the same shape as the thunderbolt we saw. ”

Hu Ben's eyes were full of solemnity, and he slowly shook his head and said: "I don't feel that it's such a simple matter, now Zhou Luquan is relying on his personal strength to maintain those two light clusters, I am afraid that without external force to maintain them, those two two clusters will not last." ”

Lian Lao Wu hummed unconvinced:

"Didn't you see that Zhou Lu was constantly debugging the balance of the two light clusters, once the debugging was successful, let the two energies stabilize down, wouldn't it be possible to maintain them without external force. ”

Tiger Ben stopped talking.

The hedgehog head snorted weirdly there:

"I hope he can succeed, otherwise, a hundred fire source stones will be wasted in vain, and I won't spare him. ”

Zhou Lu felt more and more wrong, he felt that he couldn't control it anymore, he shook it with all his strength, and the two light clusters were thrown into the cold wall over there, and the two light clusters exploded, blowing up the cold wall violently, and a boiling cold air overflowed, making the four tiger ben in the distance take a few steps back at the same time.

"Failed?"

The faces of the four of them all changed.

Even if a hundred Fire Source Stones were all thrown in vain. The failure of the experiment is not only a matter of losing the fire source stone, but also a question of whether they have the confidence to call for the Black Ice Sect in the next step, this matter is too important, the bearded old man knows how powerful it is, and he feels that his heart is about to stop beating.

The hedgehog's head and face were swollen and red, and he was about to scold angrily, but Hu Ben covered his mouth, lowered his voice and said, "Don't speak, look, what is he doing there?"

The four of them looked towards Zhou Lu.

Zhou Lu stood in the cold air like a rising tide, his eyes closed tightly, as if he had fallen into an epiphany, and he didn't open his eyes for a long time.
