In the most glorious period of the arcane Empire, large enigmatic locks were not only used for protection, but also had strong attack power. For a period of time, the highest defense command of the enigmatic lock of the high elves was "if a real dragon creature enters the range, it will automatically release the stored high-level spell sequence to attack the target."

During that period, dragons were rampant in the multiverse, and the high elves only survived under their residual power.

The definition of Enigma lock by elves and arcane masters is basically the same. It is a masterpiece of high-level magic skills, woven with magical energy. It is a powerful enchantment covering an extremely wide range. It has a simple consciousness and needs to use legendary magic to create a permanent enchantment or field.

Riddle lock has four main functions.

The first is the protective barrier. The enigma lock has a powerful protective barrier to protect the area inside the enigma lock from damage outside the enigma lock.

The second is the magic blessing. This kind of magic blessing can be activated or closed automatically, and the target can be selected. However, this kind of magic will not be activated all the time. After all, the magic consumption is too high. The mystery lock created by the ancient high elves can be opened for a long time because they once controlled a magic energy, Arcane enigma locks have this effect only after they have a miser core.

The third is to disable spells. Within the scope of this puzzle lock, you can't use spells prohibited by the puzzle lock, which is actually equivalent to banning demons.

The fourth is the start spell sequence. This is a spell stored in the puzzle lock in advance. You can start the spell by using specific gestures or specific words. The number of times of starting the spell is unlimited. Of course, the puzzle lock maker can limit the number of times of activation to reduce the price required for the effect. A spell with a limit on the number of uses can only be used several times in 24 hours.

The fifth is the resident effect. This effect cannot be directly described by spells. It can only be divided into three levels. The primary effect is equivalent to level 1 to level 3 spells or low-level spell wonders, the intermediate effect is equivalent to level 4 to level 6 spell effects or intermediate spell wonders, and the high-level effect is level 7 to level 9 spells or high-level wonders.

Hathaway has almost mastered the mystery lock technology now, but it is still difficult to make a complete mystery lock. Making a mystery lock requires the cooperation of several legendary wizards. There is only one legendary wizard, and the amount of work is too large.

At present, there is only Hathaway, a legendary wizard in Zhenbei city. If you want to build a mystery lock, you can only take your time. There are several spell casters at the level of big wizard in Zhenbei city. However, except Alex, both Karina and grace prefer warlocks. It is not easy to promote legends. As for the little demon Chris, who is also a warlock, you don't have to count on it.

Alex is a part-time wizard like Hathaway, but compared with Hathaway, Alex's knowledge is not solid. After all, she originally lived in the underground world and basically had little contact with the outside world. All kinds of knowledge are inherited from her blood. After coming to Zhenbei City, she began to learn all kinds of magic knowledge completely and systematically. If you want to master the mystery lock weaving skills, you also need to wait until she becomes a legendary wizard.

Making mystery lock has a special legendary spell of composing mystery lock. This spell needs to be made according to your own ideas.

High elves have far more talent than human beings, but they still can't avoid the fate of turning from prosperity to decline. Their blood ability began to deteriorate for unknown reasons. The former elf Empire also collapsed. After the decline of the elf Empire, human beings began to rise.

Before the rise of mankind, the languages needed to cast spells included ancient elf language, dragon language, celestial language, devil language, etc. However, after the continuous improvement of human sages from generation to generation, they finally successfully replaced them with human language. It is these people who opened the brilliant era of human magic, the era of the arcane empire.

Hathaway did not make the mystery lock after mastering the making method. After all, making the mystery lock is a huge project, which requires the joint efforts of several legendary wizards. All the mystery locks built by ancient magicians were built by a large number of magicians.

If it is a small mystery lock with a coverage of only one or two hundred meters, Hathaway can still build it in a little time, but the north wind tower needs to be upgraded into a floating tower and floating city. Naturally, this small mystery lock is not suitable.

Hathaway temporarily put aside the mystery lock production and began to study some other materials brought back by sulun - element fission and element fusion. The earliest research on this technology was in the early days of the arcane empire. At that time, the arcane masters wanted to find a way to provide more energy sources. This technology brought a new energy core, [element furnace].

The energy provided by the element furnace was 100 times or even 1000 times that provided by the element pool with the same volume before, but this technology was soon replaced by a new technology, that is, miser energy core.

Misser nuclear can clean and stably provide huge energy, even more than the capacity provided by element fission, so the element furnace technology is sealed. Misser nuclear has achieved a brilliant era of the arcane Empire, but this misser nuclear technology is mastered by those great arcane masters, and the gods are involved.

Misser energy core needs the help of magic net to obtain almost endless energy. After the war between the arcane Empire and the gods, this kind of thing will not be made again. Later arcane masters searched out the technology of element fission and element fusion from the pile of old papers and wanted to make a more powerful element furnace to replace misser energy core.

The theoretical knowledge of element fission has been available for a long time, but it is very difficult to turn the theory into a real object. It is not difficult to detonate this force at one time, but it is difficult to control the stable and continuous release of this force.

If one is careless and releases quickly, it will not be an element furnace, it will be a catastrophe. It's nothing to destroy a city, so we must be cautious. Element fusion is more difficult than element fission, and the energy released is thousands of times that of element fission.

If we really master element fusion successfully and make an element furnace for element fusion, we can directly solve the problem of building the energy core of a large floating city. Moreover, element fusion has many advantages over element fission. Element fusion is almost pollution-free, and element fission has strong radiation pollution.

It's just that it's not generally difficult to realize element fusion. With the current technical reserves of Beifeng tower, there is still a long way to go before mastering element fusion.

In addition to the element furnace technology, Hathaway began to try to repair the high-level legendary magical statue that sulun brought back from the desert ruins.

The strongest magic image in the north wind tower is the steel magic image, which is seriously inconsistent with the identity of the legendary wizard. If the legendary wizard does not deserve several legendary magic images, he is embarrassed to say hello when he goes out. In addition to those precious materials, legendary soul spar is also needed as the soul core of the legendary magic image. There are several pieces of legendary soul crystal stone in Su Lun's hand, which is enough to make several legendary magic statues.

There are many materials needed to make the legendary magic statue, especially a large amount of precious metals. If the north wind tower had not controlled an underground world and had rich mineral support, the north wind tower would have gone bankrupt. The cost of a rock magic statue is 100000 jinnars, the price of Obsidian Stone ghost statue is 150000 jinnars, and the price of steel magic statue is 500000 jinnars. As for the legendary magic statue, Suellen estimated that it would need 3 million to 5 million ginals.

Even Su Lun has some pain at this price. Sure enough, what he said is good. The wizard's strong combat effectiveness is completely hitting people with money.

North wind tower, astrological observatory.

Sulun and Hathaway are studying the element furnace together. They have mastered the theoretical knowledge of element fission for a long time. Now they are trying to design an energy core drawing of element fission.

But at this time, the voice of Tallinn Galaxy suddenly sounded: "master! Mrs. Chris has something important to report to you!..."

"Let her in!" Su Lun said with his head raised.

"Yes!"

As the voice fell, the closed door of the laboratory slowly opened, and the little demon Chris walked into the laboratory.

"What happened, Chris?" Suellen put down his notes and got up to meet him.

"Master, I just got the news that those grey dwarfs found a gold mine with refined gold when exploring minerals!" Chris said excitedly.

"Refined gold!" Su Lun's eyes brightened. It was actually a refined gold mine. You should know that the value of refined gold was no less than that of secret silver. Before, part of the refined gold used in the north town was rewarded by Su Lun, and the other part was purchased with money. The quantity was seriously insufficient. Unexpectedly, a refined gold mine was found this time. The underground world is rich in resources.

"Hathaway, I have something to leave! [element fission] you have to design it yourself!" sullen turned and said.

"Go ahead, I can finish the design by myself!" said Hathaway without raising her head.

After putting the data away, Suellen left the laboratory with Chris.

"Have you found the gold deposit and calculated the approximate reserves?" sulun asked.

"Not yet. The grey dwarves who found the gold mine said that the gold mine was occupied by other monsters, and they couldn't get too close." Chris didn't know much. When she found the refined gold, she came to tell Suellen at the first time.

"Some time ago, a small-scale earthquake occurred in the underground world, but it did not cause too many casualties. Only some mines in the mine collapsed, and the casualties were not large. However, after the earthquake, we found a new crack channel, and the gold mine was found in the underground cave behind the channel."
