Although Alvin tried to use special insulation materials in the underground space, it was still unbearable to be insulated and cooled down above the rushing magma.

In the center of the space, a transparent container was soaked in a girl in the nutrient solution. It was the juven that Alvin used his own genes to add the genes of the Magic Girl, Wolverine and Darwin to continuously integrate more mutant genes and create a juvenile body. However, there was a certain connection with the Earth's magnetic field. Alvin suspected that the Earth's consciousness was fused and was absorbing the energy in the nodes. At this time, he had grown to the age of twelve or thirteen, but he had not yet matured and should wake up after he developed.

Evan stared at the little girl curled up in the culture medium and murmured: "If you are really Earth-conscious, then you are qualified to be a contract notarized. As long as you are on Earth, the contract will be valid. Let me check your quality now."

Under Alvin's control, a metal tube penetrated into the culture tank, but at the front was a needle tube, which was accurately inserted into the blood vessels of the little girl's arm, and a tube of red blood was drawn out.

During the blood draw process, Alvin stared at the little girl's changes and was careful. If an accident occurred, he would run away immediately without any hesitation.

Fortunately, everything went smoothly, except when the blood was drawn at the beginning, the sleeping little girl frowned, and seemed a little uncomfortable, but she quickly returned to her calmness and fell into a deep sleep again.

It was not until the blood was drawn that Ai Bian got the tube of blood that he breathed a sigh of relief, returned to the ground as quickly as possible, arrived at the laboratory of the castle, and began to make his favorite magic props.

Alvin had a draft of the magic props from the beginning, and there was no hesitation in the production.

Alvin took out all the magic metals and various rare materials he had collected over the years, chose the most suitable one, and directly used his own abilities to decompose and reorganize them, and each part appeared one by one. Alvin also burned dense magic runes on it.

Finally, when Ai Wei assembled all the parts, the scale that was more than one foot long was presented in front of him.

The scales made by Alvin are extremely exquisite, and the magic circles composed of magic runes look like a mysterious pattern, giving people a mysterious feeling.

Alvin is very satisfied with the work in front of him, but this has not been completely completed. The next step is the most important one.

Alvin held the information about the origin of the trading rules with silver light in his hand. He gently tapped the pointer close to the level of the day, and the origin of the transaction immediately merged into the pointer of the balance. Then Alvin quickly poured a tube of freshness onto the balance.

A wonderful thing happened. The magic runes on the balance lit up one by one, as if they were coming alive, connecting with each other, forming strange magic circuits. A magical energy was flowing along the magic circuit, and the light became brighter and brighter, wrapping the balance in. With Alvin's mental power, he could only faintly feel that the balance in the light ball seemed to undergo some magical change.

The dazzling light lasted for more than ten minutes, then slowly converged and finally disappeared completely, leaving only a faint magic halo surrounding the balance. This magic rune has disappeared and completely hidden inside the balance. The overall balance looks golden yellow, with a sense of sacredness than before.

"It's really successful!" Alvin walked over, stroked the balance with his hand, and murmured.

As the maker of the scale, Alvin quickly understood the function of the scale. As long as Alvin stimulates the ability of the scale, and then under the testimony of the scale, both parties who sign the contract can get the witness of the earth consciousness. The contract will preserve the energy of both parties and the earth consciousness. After signing the contract, it must be done. No matter who is destroyed, it will be erased by this energy.

"Then we need to see how the effect is. We also need to prepare some paper for contracts. Ordinary paper is not good. Use paper with magical effect. By the way, when I was reading books at the Hogwarts Library, there was a method of making magic potions. After soaking parchment paper with it, it would form a paper with magical effect."

"However, the contract written in parchment can only restrain ordinary people. For those powerful wizards, it is best to use dragon velvet paper. There are wizards who specialize in selling materials on fire dragons in the magic world. Bojin Boke can help me collect some. However, for some higher-level existences, contract paper with stronger contract effect is also needed. It seems that Smaug can only be wronged. It has now stimulated the bloodline of the ancient dragon clan. It will not take a little dragon skin from it to recover in a long time. It should be nothing."

Alvin has many magical magic items, high-tech equipment and various strange things in his hands. However, after Alvin has studied them, he has figured out their principles and it is not very useful to keep them in his hands. It is better to use these to exchange for some other things. However, there was no effective exchange method before, but now he finally found a way out. Alvin seemed to have seen countless numbers, and various magical items rushed towards him.

The more I thought about it, the more excited I became, and I couldn't wait for a moment, but the most important thing now is to try out how effective the trading balance is?

He said to Honghou and soon sent the magic materials that Alvin needed. He only took more than ten minutes to configure the magic potion he needed and soaked a few pieces of parchment paper. Soon Alvin got the magic contract paper he needed. Next, he had to find a little white mouse for experimentation.

"Mr. Red Queen, let Shanshan pick an elf couple from Skull Island."

Not long after, the domestic elves Shinzhang brought two elves to the castle. At this time, the elf couple had no idea that they were going to become Alvin's experimental lie mice. They were looking at the towering and tall castle. They were shocked by this magical building when they came here for the first time.

"There is a contract here. You can check it out. If there is no problem, you can sign it." Alvin did not say nonsense and threw a parchment contract in front of the two elves.

After saying that, Alvin began to fiddle with the golden balance on the table in front of him, and he didn't look at the two elves directly, as if the two house elves were irrelevant at all.

Although Alvin's attitude is not bad, it is definitely not liked by people, but the elf has no intention of complaining, because the slavery of the house elves has penetrated into their bones. In their opinion, serving the master is an honor, and even if they are asked to die, there will be no resistance. The elves' curses can affect their hearts.

The two elves were frightened by Aiwen's inexplicable request, but they had no intention of resisting. Of course, even if they wanted to resist, they could not resist. They were the ones who were the ones, and I was the ones. Although I didn't know what Alvin was doing, I still honestly grabbed the parchment contract and started to read it.

When a couple of elfs saw the contents of the contract, they couldn't help but breathe a sigh of relief. The contents of this contract were not harsh, nor were they asking them to do any dangerous tasks. They were just a love contract. The contract stipulated that they could only love each other in this life and could not fall in love with other elfs anymore.

This was not a difficult task for the two elves, so immediately cut off their dirty claws and wrote their names on their thoughts according to Alvin's request.

A magical scene happened. When the two elves wrote down their names, the golden scale suddenly projected a golden light into the parchment contract. Then the two names on the contract seemed to burn and merge into a ball, then split into two, and drilled into the foreheads of the two elves.

"How is it? What do you feel? Tell me quickly!" Alvin, who had been observing the two elves, asked impatiently.

"Ah? Uh..." The two house elves were touching their foreheads, feeling strange about what had just been burying into their minds, and were wondering if they were confused. At this time, they heard Alvin's questioning and did not react for a moment.

"What, what do you think? Just say it, don't talk too much." Alvin added angrily.

The elf then realized, and one of them hurriedly said, "It doesn't feel anything special, it seems that there is something in my mind. It's a wonderful feeling. The content of the contract is like it is printed in my mind. It's easy to understand the content of the contract. I know very clearly that if I violate the contract, I will be punished severely and even lose my life."

Another elf nodded in agreement, and it also felt the same.

"Hahaha! Success, I really succeeded, I am such a genius, wow..." Alvin laughed loudly, and a burst of crazy words came to his mouth.

"That... Master, are you okay? Do you want me to call you a doctor?" The two elves were so scared that they almost hugged each other. They suspected that their owner had some crazy illness, and maybe they should take some medicine to treat it.

Alvin's laughter stopped abruptly. Even if he had no use to sense the two elves' thoughts, he could guess it just by looking at their expressions. He suddenly felt in a good mood and stared at them with his eyes tightly. He said angrily: "Okay, there is nothing you have to do here, get out of here! There is also what happened here today. Don't tell anyone, otherwise you will be killed."

"Okay, master!" Two elves spitted with difficulty. Facing Alvin's threatening eyes, he agreed without hesitation. At the same time, he turned around and walked out the door and ran as fast as possible. The two small figures quickly disappeared.

Alvin stared at the balance on the table, looking left and right, it was always not enough. Now that we have a trading balance, we can pretend to be a devil and make a deal with people, but Alvin can't go and sell his things to ordinary people, it's too arrogant.

"It seems that I have to create a magical item, a place specifically used to trade with people. It must be magical, unique, and mysterious. I have to package it well so that I can give the people who trade confidence and improve my own personality."
