Time flies, and half a year has passed in a blink of an eye.

In the past six months, Zhang Sen completely abandoned his practice and immersed himself in the vast knowledge of the Book of Truth.

His life was so fulfilling that his brain was like a sponge constantly absorbing sea water. Finally, he found that he couldn't understand what was going on, so he stopped reading.

Wizards have always been knowledgeable and remembered.

A wizard who has lived for thousands of years is basically equivalent to a mobile library. A wizard who has lived for thousands of years is synonymous with horror. Even a scholar-type wizard has unimaginable means and trump cards until this year.

Zhang Sen did not have a teacher's teaching, so he embarked on the path of a wizard entirely through self-study. The only thing he could use as a reference in the past was the dead undead wizard, so his path was very wild.

Now that he has obtained the Book of Truth, he is like getting a regular textbook and finally has truly entered the world of wizards.

Zhang Sen carefully closed the Book of Truth and put it in the dimensional safe, then he left the study and went to the laboratory.

To be honest, he has been exposed to too much theoretical knowledge in the past six months, and now this knowledge is in his mind. All he needs to do is transform it into strength.

The first thing he had to do was prepare the materials. There were many special spells that did not have much learning value, but the process of using them greatly improved the personal realm.

For example, phonic art is just a level 1 spell, which can build a mana channel to transmit sound to the designated object.

The problem is that this mana channel can be easily intercepted by the enemy, so no wizard can use this spell at all, but this spell is the basis of the True Word Technique. If you can learn this spell, it will be much easier to learn the True Word Technique.

There are many similar situations, even combining several completely useless spells together, but forming powerful spells.

Zhang Sen already knows how to learn these spells, but to use these spells, it takes some materials to consume, so he has to find a way to get the materials.

After entering the laboratory, he took out a piece of space debris and then took out a full-body mirror.

He quickly used the space fragments to arrange a special mirror space on the full-body mirror, and then he drilled into the mirror and constantly made magic marks in the space inside the mirror, each mark containing different coordinates.

To be honest, if he hadn't read the Book of Truth, he would probably have known how the wizard traded a long time later.

Wizards usually live alone. The stronger the wizards, the more they like to live alone, and often hate dealing with various interpersonal relationships.

Although there are a few wizards who like to drill into the crowd, at least most wizards are lonely explorers. They will only step out of their wizard tower when they need to collect experimental materials.

Later, several god-level wizards felt that doing this was too wasteful, so they created a spell together, that is, the Mirror Realm Trading Technique.

The so-called mirror world is the time in the mirror, which reflects the real world. Every wizard can use the mirror world trading technique to build his own shop in a mirror, and highlight the coordinates and wait for the guests to visit.

Because many of the wizards are bloodthirsty people, these god-level wizards used three god-level spells in the mirror world, forming three major laws: to eliminate identity spying, to eliminate mutual attacks, and to eliminate coordinate spying.

In order to ensure the effectiveness of the spells, they were said to have invited a terrifying powerful man to strengthen these three spells in the mirror world. So when it comes to transactions between wizards, it can be said that the safest place in the mirror world.

Because the monster jaw wizard was originally a wild path, he did not know the information about the trading technique of the Mirror Realm. Naturally, the dead necromancer did not know the trading technique of the Mirror Realm.

If Zhang Sen had not obtained the Book of Truth, it would probably take a long time or even a lot of money to know the existence of the Mirror Realm.

Therefore, Zhang Sen was actually lucky to meet Huangdi.

Zhang Sen built his mirror world space into a grocery store, then took out a door and installed it on the space barrier, and continued to cast spells to connect the door and the mirror world.

The Mirror Realm is actually a very long road. Anyone who sets a realm space with a wizard, the road will extend ten meters, and these ten meters belong to the facade of the wizard.

In fact, there was a charge for setting up a storefront in the mirror world. Later, the terrifying existence took the initiative to strengthen the three major spells for free, so that the charge was exempted. Zhang Sen didn't know what was going on, but this was good news for him.

After setting up the door, he put on a mask and put on a black cloak, opened the door and walked out.

On his left is a twisted space, and on his right is a long road with no end to see.

There are many doors of different shapes on this road. If they open, they will automatically open as soon as they get close to the past, while if they do not open, they will still be closed.

Zhang Sen took a deep breath and walked towards the road.

Obviously, all the shops close to his shop were newly opened, and they were not ready. The door was not open at all when he passed by.

He kept walking forward and gradually began to see people who were dressed similarly to him, wearing black cloaks, either wearing masks or using spells to cover up. Some were even more weird, and seemed to be completely unwilling to reveal their true faces, but their true faces made Zhang Sen feel like human skin and masks.

As more and more people were coming, Zhang Sen finally saw a shop that opened the door to do business.

He walked into a shop and it looked very dark, and the whole shop was filled with all kinds of weird things.

“Guest, what do you need?”

At this time, a frog asked at the front desk of the store.

Zhang Sen noticed the frog and said, "I need some spell casting materials, I don't know how to trade it?"

"Is the guest coming to the mirror world for the first time?" The frog asked with two scarlet eyes staring at Zhang Sen.

Zhang Sen nodded and said, "It's indeed the first time I'm here. I wonder if the rules here have changed. Do you still use magic stone to settle the settlement?"

"Use magic stone to settle? The guest is talking about several things from the past of the Celestial Chronicle. Now everyone uses the common currency of the nine major worlds, "The Frog looked at Zhang Sen and said.

Zhang Sen nodded and said, "Is it acceptable to barter?"

"Sorry, this store does not accept barter, but you can get things to sell in this store." The frog replied.

Zhang Sen nodded, then politely expressed his gratitude to the frog, and turned around and left the store.

He then visited several stores and finally figured out the current trading model of the mirror world.

The so-called nine worlds are actually super-large countries born before the five universe eras. It is said that a powerful and unimaginable powerful integrated these nine worlds and established a country based on these nine worlds. The name of this country is Yongyuan Country, and the common currency in China is Yongyuan Coin, abbreviated as Yongyuan.

There is a world that all practitioners dream of, with countless resources for practice and unimaginable strong people.

Nearly nine out of ten wizards in the multiverse moved into the Eternal Kingdom, and naturally the trading model of the Mirror Realm also changed, gradually changing from charging only magic stones to charging only Yongyuan.

Yongyuan is a currency similar to gold coins, with a handsome man engraved on it, and a dragon is carved on the other side, and the word "forever" is in the middle of the dragon.

This currency itself has no special purpose. Unlike magic stones that can assist in cultivation, it has one feature that can be guaranteed to be imitated, and that feature is that it cannot be destroyed!

No matter how many means, it is impossible to destroy Yongyuan. Some local tyrants even used Yongyuan to make an armor, which had amazing defense. If there were no gaps, it would be an invincible armor.

Zhang Sen basically only looked at it but not bought it along the way, and kept asking for various information.

This information is not confidential, it is common knowledge that most wizards know. Although the clerks in these shops all saw that Zhang Sen was a poor man, they were still willing to tell Zhang Sen this information. After all, wizards have a long lifespan, so who knows what level Zhang Sen will grow to in the future.

Zhang Sen also found that these stores basically won’t meet the owner.

The shop owners here are all wizards, and most of the time they spend in the laboratory doing experiments. How could they waste time looking at the shop?

So generally speaking, the shop is either a wizard or an apprentice or an alchemy puppet, and there are even an undead.

Although the necromancer is a person who is called to beat everyone, the mirror world can block identity and spy, and most customers can't do anything even if they know that the store was opened by the necromancer. When the transaction is made, there will be no change because the other party is the necromancer.

There is also the store purchasing items, and the price is really bad.

Zhang Sen saw that the price of space debris in a store was 10 Yongyuan, while the price of recycling in the store was 1 Yongyuan.

Finally, he made up one thing. If he wanted to buy materials for experiments, the first thing he had to do was to make money!

If he sells the goods to the store, it will be useless even if he throws his entire fortune in it.

But now he is not in a hurry. Since he has decided to stay in the mirror world, the first thing he needs to do is market research, understand the rules, and also understand the prices.

The streets of Jingjie have a characteristic. Zhang Sen discovered as he walked, that is, the more people they walked forward, which means that the higher the shops, the greater the advantages.

Then the question is, how should a store like his survive? You must know that no one went to the location of his store!

Finally, he thought of a solution, which was to unite with other shops.

If the customer wants to buy something that he does not have these shops, he can introduce his shop. If he sells the goods, he will give the introduced shop a 10% profit.

He returned to the castle to make a plan. After confirming that there were no loopholes, he took the plan and came to the mirror world again.

But the result hit him a lot, and basically all the shops rejected his plan.

The only thing that made him feel a little bit excited was news.
