The dean's office was already a mess. Lin En quickly stopped the supply of magic power. The storm immediately dissipated, and fine iron sand fell to the ground, making a series of "clicking" sounds.

"The magic power consumed is about 6 scales!" Lin En sensed the magic power reserves in his body and immediately came to a conclusion.

This is the case when there is ready-made iron element, but if it relies entirely on magical mimicry, the magic consumption will probably be more than thirty magic scales, which is a relatively standard fourth-ring spell.

That is to say, with his current status as a three-ring wizard, under the best condition, the limit is to release three four-ring spells, and this is when the intelligent brain takes on part of the computing power and magic power consumption.

This is when the magic power he possesses far exceeds that of wizards of the same level. If he were an ordinary three-ring wizard, he might not be able to successfully cast a four-ring magic even if he exhausted all his magic power.

It can be seen that there is a qualitative gap between formal wizards and great wizards...

Lin En shook his head. Although his strength had improved quickly enough, with the help of mental fusion and the fusion potion of "Eye of Death", it only took him about a year to skip levels and become a three-ring wizard.

But this is obviously not enough to deal with the increasingly complex situation.

The fastest record in the entire Wizarding Land for being promoted from an official wizard to a great wizard is four years!

However, the record holder, August, has been proven to have cheated and his reputation has been ruined, so he cannot be used as a reference at all.

Fortunately, Lin En has his own "cheating" method. With the help of the computing power improvement brought by the magic network, he can do many things that only great wizards can do in advance, such as casting four-ring magic and using magic to mimic metal elements.

This is an unprecedented training for mental strength. In the past three months, Lin En's mental strength assessment and the total amount of magic power have increased a lot. Most importantly, after adapting to this state, there will be no obstacles to the promotion to a great wizard! What he lacks now is accumulation, and he doesn't know if he can catch up with the day when the war between the wizard land and the church breaks out.

Lin En quickly adjusted his mindset and began to study how to further improve the lethality of these spells.

Among the magic he now possesses, the most destructive one is [Space Vibration]. However, without Aurora's magic blessing, it can only be used against enemies within five meters of him. Otherwise, its power will be greatly reduced and it will no longer be able to threaten a great wizard.

The [Iron Sand Storm] is a supplement to the medium-range attack methods. There are many variations of this spell. In addition to turning it into an iron sand meat grinder like this, it can also create a large amount of iron thorns like Hellram. In the final analysis, it is just a means of controlling the iron element.

There are subtle differences in everyone's spell models and constructed spell slots, it all depends on how they are used.

The only things that can work well with metals like iron and copper are electricity and magnetism! If you can use it with lightning magic, you should be able to greatly increase the power of [Iron Sand Storm]. The feeling of being caught in an electrified meat grinder must be very painful! You can also use the electric and magnetic fields created by the current to control the iron sand and perform a second or even third strike, making it hard to defend yourself...

Isn't that Magneto?

Lin En immediately thought of a character in a movie from ancient times, and then looked at a small generator placed in the corner, which was replicated using the magnet Cody gave him.

Compared to people like Abel who can only store the high-voltage lightning during thunderstorms and weaken it through protective magic, he can generate electricity on his own and control the intensity, so he will not be in any danger when he is electrocuted...

Under the temptation of controlling electromagnetic force, Lin En hesitated for only a few seconds before using the [Mage's Hand] to lift up the generator.

Over the next few days, Lynn spent his time practicing magic and receiving electrotherapy. He occasionally entered the magic realm to explain difficult calculus problems to Anthony, and also learned a lot of tips on practicing thunder magic from Anthony.

Normally, it would take three to four months, or even more than half a year, from receiving 'electrotherapy' to initially mastering magical mimicry of lightning, but it only took Lin En four days.

Because he was electrocuted dozens of times a day, he was trembling all over! According to the data in the intelligent brain, the safe current that the human body can accept is only 10 milliamperes, and the safe voltage it can withstand is 36 volts.

However, after personal experience, Lynn discovered that wizards have very strong physical fitness, coupled with the resistance brought by the magic power in their cells, they can withstand hundreds of volts of high voltage electricity almost without damage.

Not only that, his resistance to electric current continues to increase, which means that magic is gradually becoming familiar with this new power of lightning.

Various industries in Yieta Port are also developing rapidly. Every three days, the airship will transport batches of scarce ores to the square, and then they will be pulled by alchemy vehicles and distributed to various workshops.

The entire Yieta is like a huge war machine, with each person acting as a part, continuously assembling and producing war supplies.

With sufficient materials, the musket workshop expanded several times and produced a total of 1,500 finished muskets in one month, which was three times his previous estimate.

When Lin En heard Philip's report, he was completely stunned. He almost suspected that the other party was fooling him, or that the Alchemy Research Institute had developed some new magic.

For example, putting the materials needed to make a musket into an alchemy array, and then clapping your hands, the thing will be made!

It was not until he personally visited the workshop that Lin En realized that he had underestimated the enthusiasm of the poor people for work. These people worked almost sixteen hours a day without any rest. They worked whenever they woke up.

You have to know that each workshop can only recruit a limited number of people, and there are countless poor people outside who want to replace them and get the job.

Lin En hesitated for a long time, and finally just forced himself to sleep, eat and rest for ten hours a day, with one day off every half a month, so as not to be overwhelmed by the high-intensity work.

With the current productivity of the Iyeta Port, it is still far from being luxurious enough to consider human rights.

Having food to eat, a place to live, and security is the greatest happiness in this era! (End of this chapter)
