Now that the decision has been made, and the money is not bad, the next thing is simple.

Qin Feng sent fifty tons of Mithril the next day, and Barroso deposited it in his own name in the empire's largest royal royal Rose Bank, and obtained a credit guarantee worth 200,000 high-purity magic crystals issued by the person in charge of the bank.

With his status, no one doubts his creditworthiness and ability to repay. Although this huge amount of money is quite a lot of money even for an empire.

As a high-level member of the Magic Guild, and in accordance with the procedures, the human and material resources that Barroso can call on are extremely considerable. In less than a month, materials and equipment worth 50,000 high-purity magic crystals were successively sent to the imperial capital from all over the mainland.

In addition, a huge construction team composed of more than 3,000 professionals, tens of thousands of high-level slaves, and many alchemical construction machines has been formed, including more than 20 legendary mages, as well as many great astrologers, senior alchemists, great rune masters, legendary master craftsmen, etc., and there are more than 400 talents at the Sanctuary level.

Inside the Magic Guild, a large remote space portal has been built, through which these people will reach the half-plane of the void and begin construction. Their lodging and salary were also staggering, and they had to be paid for by the half-dimensional masters.

Barroso took the time to take Qin Feng to visit the National Alchemy Experimental Base of the Grossas Dragon Empire, which was also a giant half-plane located outside the void, with an area similar to Qin Feng's.

On the floating island of the void shrouded in a beautiful pale blue light curtain, there are twelve magnificent magic towers with a height of 500 meters, countless outbuildings, as well as an arcane tower area, an elemental pool area, a space portal area, a large number of alchemy golems, and so on.

It covers an area of several hundred square kilometers in a half-plane, with mountain peaks, rivers, lakes, plains and other terrain, although it seems to be a little small in size. The air is fresh and fragrant, and the free magic elements are extremely abundant, which is not inferior to those in the high-level meditation room, and the effect of cultivation here is undoubted.

There are many rare plant medicinal materials cultivated on the plains, and some rare small animals are also kept in captivity, which are all raw materials used to prepare high-grade magic potions and alchemy potions.

In the center of the plain there are three lakes with a radius of several hundred meters, and the liquid in them is all magical springs.

Qin Feng tasted it and confirmed that the legendary mage could use it to directly replenish mana, or after bottling, it could be sold as a high-quality powerful magic recovery potion.

At the bottom of the lake, you can clearly see a large number of solid high-purity magic crystals, which are the products of the precipitation and solidification of the magic spring water.

On the other side of the lake, there are several small mountain ranges, and the whole is also completely composed of magic crystals, all of which are derived from the giant magic array laid out in the half-plane, which has been running for many years, absorbing the energy of the infinite void and gradually transforming it.

“…… The empire began to build this half-plane two hundred years ago, and it took decades for the Ministry of Finance to allocate a large amount of special funds every year, and with the participation of many powerful members of the royal mage group. ”

"This is an important strategic asset belonging to the empire, and some important large-scale magic experiments, high-risk alchemy equipment research, and batch training of high-level professionals can all be carried out here."

"See the portal area over there, right? There are a total of 25 permanent spatial portals, leading to the imperial capital and the 17 most important frontier towns of the empire, which can quickly mobilize high-end combat power and materials to support the front line at critical moments. ”

"The remaining seven portals lead to three other giant half-planes, as well as four special Peerless Realms, which are extremely dangerous and have some special resources, which are the most important exotic mines in the Empire......"

"Such a mature giant half-plane can generate huge wealth and income for the empire every year, and is an important part of the empire's powerful national strength. In view of its important value, there are two super powerhouses and a number of veteran legends in it at all times, and in the event of an emergency, the support of the imperial capital will arrive in a very short time. ”

"At present, the empire is considering the construction of the fourth giant half-plane, and other countries on the continent with conditions will almost consider making one or two half-planes, even if it is not that big, and they can get a lot of benefits after they are operated."

Barroso patiently explained to him that in this era, the size and number of common half-planes are also one of the important criteria for measuring the comprehensive strength of a country.

Qin Feng smiled secretly in his heart, isn't this the space base and synchronous orbit workshop equivalent to the doomsday world? Each base is like a cash cow, and as long as it is in normal operation in the sky, it can continue to generate huge wealth for the empire.

The space exploration and development of the main world has not yet reached such a stage, but the International Space Station, as well as the Tiangong Laboratory in Huaguo, have achieved a lot of results every year.

In the future, after he establishes a country in the Xingmeng World, he can't be stingy with his investment in this area.

"How long will it take for my half-plane to be completed?" He asked.

Barroso said, "About half a year. However, to keep this giant half-plane functioning normally, you'll have to prepare the alchemy golem at that time. ”

Qin Feng was quite satisfied with this answer. With it as a backing, his cultivation speed will inevitably soar again.

As for the problem that it takes decades for the empire to build a half-plane, it is not difficult to understand that the empire has a great cause and there are too many places to spend money, so the amount of money invested in the construction of the half-plane every year must be limited. And Qin Feng didn't have such trouble, as long as the resources were smashed in place, no matter how many half-planes could be built quickly.

Barroso thought for a moment, and then said, "After the half-plane is completed, you should transfer it to a safe void as soon as possible, and don't reveal it to anyone. ”

This kind of giant half-plane that is no different from Jinshan is not available to most demigod-level powerhouses, and if it is known that its true owner is Qin Feng, it will definitely cause countless troubles. Therefore, the construction of the half-plane, Barroso has always been carried out in his own name, and outsiders have no idea what happened.

It costs a lot of money to move the half-plane, so many legendary mages will choose the calm void as the mooring area of the half-plane, which is rare to move once in a hundred years.

However, this brings up another problem, as some races that excel at stealth and can roam freely in the Void are specifically fond of finding and stealing half-planes for a living. A careless man can often bring a terrible loss to the owner of the half-plane.

Legendary mages hate such half-plane thieves, but they can't stay in the half-plane forever. Therefore, it is better to arrange more magic contract guards, alchemy golems, strengthen the defense of the half-plane shield, and so on.

When the two returned to the imperial capital, they continued to handle the construction of the half-plane.

This kind of project is not trivial, and it is even related to Qin Feng's future god-sealing plan, so it is impossible for him to be the shopkeeper, he must often watch on the spot, and some key issues can only be decided by him how to deal with them.

So in the next half a year, in addition to the indispensable class cultivation, Qin Feng basically stayed in the half-plane, so busy that he couldn't find the north, and the slaves he bought were also involved in the project.

Of course, no one knew that he was building his own half-plane except for Barroso and the five soul guards, and when Lorilan and Aaron came to him, he only said that he was helping the teacher.

Over time, twelve giant magic towers were built one after another, followed by large-scale terraping, laying magic arrays throughout the entire half-plane, building elemental pools, magic laboratories, alchemy laboratories, barracks, warehouses, portals, and more.

During this period, he successfully crossed the threshold of level 22, of course, it is still kept secret from the outside world.

When the last facility on the half-plane was completed, Qin Fengdang even controlled it to have a spatial teleportation, consuming hundreds of millions of gold coins worth of magic crystals for this, after all, this thing was too big.

When he and Barroso finally settled the accounts, they found that the various expenses had added up to an astonishing 580,000 high-purity magic crystals, more than double the normal cost.

This is not surprising, Qin Feng is asking for high efficiency, not to mention anything else, just that large spatial portal sends tens of thousands of people in and out, and the cost of magic crystals is not a small amount.

There are still more than 10,000 magic crystals on the account, Qin Feng thought about it for a while, and simply gave it all to Barroso, this big guy has helped him a lot, there must be more places that need his support in the future, and it is appropriate to give him some benefits.

"The news of my promotion to the legend will be released to the public tomorrow."

Qin Feng said, after completing this major event, he has no worries, even if the people of the Mage Alliance want to kill him, it will not be so easy.

Perhaps, I should go back to the apocalyptic world now and bring some weapons and equipment that I can use.
