To the Bone Demon, the crystal ball is as small as a grain of sand, but it does not hinder the Bone Demon's soul observation.

This skull demon was obviously shocked by the wizard's leverage of the rule, which amplified the insignificant energy to infinite magical abilities.

"Okay, take advantage of this time, my time and space communication altar has some residual energy, and we will conduct a regular transaction. What do you need, Lord Bone Demon?"

Green raised his head, and the elemental eyes under the face of truth looked at the bone demon. Just now, the exchange of tokens between the two sides consumed a lot of altar crystal energy.

The Bone Demon Soul laughed out loud during communication.

"Hahahaha, I need the bones of powerful creatures, such as... this skull in your hand!"

The bone demon actually fell in love with the skull of the world of Green's Horned Skull magic wand, which was the medium used by the Hesota Holy Scar wizard to seal the shadow of the nightmare!

The skull, the master of the world, this skull demon has vision.

Green sneered in his heart, but said calmly on the surface: "I want my magic wand? So, what can you give?"

Green did not think that the other party could take out something that would allow him to abandon the magic wand of the Horned Skull. In Green's thinking, the skull of the world's master skull and the magic wand of the Horned Skull are connected, and the value of the magic wand of the Horned Skull...

Although he sneered in his heart, due to the basic etiquette of equal communication with creatures in foreign worlds, Green did not immediately refuse to refuse the other party before the other party took the price code.

Distant foreign space-time transactions often represent the different rules of the two sides to learn from each other's strengths and weaknesses. Perhaps something without any value in this world is priceless in the other's world, especially when low-level creatures conduct transactions.

Maybe the other party can take out a higher-level treasure that is more moved by Green and is willing to abandon the magic wand of the Sheep Horn?

After thinking about it, the Bone Demon "vapies" and a ball of soul fire was spit out of his mouth.

The flame was purple-black, about two meters high. After falling into the bone hand, it squeezed hard and was immediately compressed to the size of a crystal ball. At the same time, a ball of purple-black aura dissipated and turned into an extremely pure transparent soul fire.

"This soul fire has a total of 250,000 Boluns, and in terms of wheel value..."

Green was extremely disappointed. For Green, who frequently participated in the World War, collecting souls was really simple. Perhaps for the Bone Demon World, souls were their standard currency and important materials for hoarding, but they were of no value to most wizards in the Wizard World.

This skull demon seems to be an existence that has been interacting with creatures in foreign worlds all year round. He was extremely sensitive to Green's unhappiness and hurriedly said, "So, what do you need in exchange?"

After thinking about a few breaths, Green said in a deep voice: "Materials that are more conducive to energy-guided, or... knowledge!"

"Knowledge?"

The Bone Demon murmured to himself for a moment, slowly shook his head, and the other bone hand suddenly pulled out of his eye socket and took out a large piece of blue ice?

"This is a world master who broke into the world of bone demons. After being killed by several powerful bone kings, the materials I picked up from the battle ruins should meet your conditions."

Under the truth, Green's eyes grew apart the moment when the Bone Demon took out this piece of blue ice.

"Extremely cold crystal!"

Green recognized the materials that the Bone Demon took out at a glance.

Among the legendary alchemy materials of some ancient wizards, the extreme cold crystal is an advanced alchemy material of the same level as the alienated marrow of the Green Truth.

The higher the alchemy material, the more prominent the ductility requirements are. In this way, the witchcraft can be large or small and change endlessly. It has many wonderful uses, and the melting and condensation ductility of the extremely cold crystal is almost comparable to that of the alien marrow, and it also has high energy use of ice attributes.

Now the extremely cold crystal held by the Bone Demon's palm is like a hill for Green.

Even if these extreme cold crystals are completely released, they will expand infinitely until the end of their own cold power condenses energy. At that time, its size will not be determined, as if it is a real mountain.

This is the extension performance of extreme cold crystals.

And if it collects its cold power, it is not surprising that this small iceberg of more than ten meters shrinks to the size of a fist.

Green fell silent, and the energy from the altar under his feet was consuming and passing by bit. Suddenly, Green seemed to have made a decision and shouted in a low voice: "Trade!"

Losing the Horned Skull Magic Staff will indeed reduce Green's combat power at this time, but if he obtains this extremely cold crystal, Green will have the basis to make a higher-level magic Staff!

In the skull's eye sockets surrounded by purple-black poisonous breath, the soul fire jumped excitedly. Then the extremely cold crystal became smaller and smaller in its palm, shrinking to about the same size as the Green crystal ball. On one side, Green slowly pushed the sheep-horned nightmares into the time and space vortex, and on the other side, the Bone Demon handed over the extreme cold crystal from another world.

Almost at the same time, the two got what they wanted.

"Hahahaha, the cooperation is pleasant, the strong man in the foreign land, I hope we have a chance to cooperate next time. I am the head of the Three Soul Bone. What is your name?"

The moment the huge bone demon got the magic wand of the sheephorn, he pulled out the magic wand with his other hand, took a look at the metal material and stuffed it into his eye sockets. Then he couldn't wait to throw the skull into his mouth and swallowed it into his stomach.

"Shadow of Despair!"

The extremely cold crystals of the crystal ball-sized crystal in Green's hand were surrounded by blue cold air, but they gradually gathered under the constraints of the rules of the Green's World Clothes. Then the extremely cold crystals of the crystal ball-sized crystal in his hand shrank again, gradually turning into the size of a fist, and were thrown into the dimension gap by Green.

“Happy cooperation.”

With Green's words, the crystal energy on the magic altar was exhausted, and the communication between time and space ended, Green also restored his half-step perception of three-eighth second.

call……

After a light breath, Green was in a good mood.

"It's really interesting. No wonder those creatures who can communicate with foreign worlds in the demon hunting world are regarded as prophets, saints, and wise people in the world..."

While murmuring to himself, Green once again became invisible under the robe of appearance, temporarily forgot about this matter, and continued to look through the collection of old wizards in the underground secret room.

About five hourglass time passed.

The old wizard brought cappuccino back to this underground laboratory again. The old wizard buried his head in the experiment on the experimental table, as if he was still looking for the cause of yesterday's failure, thinking that he had done something flawed.

On the other side, the little girl hummed a song, jumped to the laboratory and ignored her grandfather. When she arrived at the center of the laboratory, she was suddenly stunned.

Cappuccino slowly walked to the altar and observed it carefully for a while, and then looked suspicious, then turned his head and began to look around the room, as if he had noticed something different.
