Are you addicted to fairy? Just give it a try!

To be precise, Zhang Wei has no plans to delve into the formation.

But just like learning alchemy, learn a skill just in case.

In order to avoid being trapped by formations when he traveled to various countries in the future, Zhang Wei carefully studied the formation inheritance of Master Luoxia, a third-level formation master.

In the past few years, Zhang Wei can be regarded as a half-assed formation master. However, compared to other orthodox formation masters, Zhang Wei has great limitations in deploying formations and his methods are very rough.

But there is no problem in setting up a formation to control the wind and rain.

For this reason, Zhang Wei even used the entire eastern suburbs of Luyang County as a place for the array formation, and spent money to buy several areas as the eyes of the wind-calling rain array.

In each formation, Zhang Wei buried hundreds of taels of spirit stones as energy supply, and then used thousands of taels of gold and tens of thousands of silver as energy running patterns.

That's right, gold and silver can also be used to set up formations in addition to drawing charms and refining weapons! Zhang Wei felt that these two brothers were capable of anything!

Moreover, this formation still needs maintenance, because every time it is started or even operated for a long time, it will consume the two uncles. Therefore, if Zhang Wei wants to start the formation again, he has to dig into the small vault for maintenance.

This made Zhang Wei have to sigh.

No wonder the formation mage is the most difficult to achieve among the four major professions. With this starting cost, it is not at the same level as the other three!

This is just a first-level formation, and it uses so much silver and gold. How much does it cost to protect the formations of foundation-building families and large sects?

Zhang Wei no longer dared to think about it.

As each formation eye was lit up by spiritual stones, the spiritual energy between heaven and earth slowly changed. As the water vapor surged, the originally clear sky gradually became cloudy.

"Is it going to rain today?"

In the farmland outside Luyang City, several old farmers looked up at the gloomy sky and muttered.

As soon as he finished speaking, there was only a rumble, and a muffled thunder resounded through the sky, shocking the hearts of several people.

Someone sighed: "Oh, the rain looks quite heavy."

"It's good to have rain. Since the beginning of spring, it has rained only a handful of times in Luyang County. I'm still afraid that God will cause a severe drought." A man said while carrying farm tools on his shoulders.

"Brothers, let's take a rest on the roadside and see if it rains. If it rains, go home quickly. Don't get caught in the rain and get cold."

Upon hearing this, several other farmers also put away their farm tools, and those who could afford it took the lead in putting on raincoats.

One person walked towards the roadside and said, "It's still a severe drought. Don't you know that the east side is about to be flooded?"

Someone immediately replied: "I know that. What about the tsunami? The immortals figured it out. Now many people from the East China Sea have begun to run to our side, which has caused the price of food here to rise. few."

"But no matter how they are flooded, it's not our turn. We in Luyang are thousands of miles away from the East China Sea! Just live your own life, and it's not our turn to take care of things over there." The old farmer sneered disdainfully.

At this moment, there was another muffled thunder in the sky, and then drops of rain fell, dyeing the ground almost in the blink of an eye.

The farmers who were still working in the fields hurriedly braved the rain and rushed towards their homes.

"Hiss--the rain is quite heavy..."

On the other side, on the top of a mountain outside Luyang City, a strange-looking iron tower had been quietly erected at some point.

The style of the iron tower is very strange. It is built entirely of metal pipes, with a hollow center and only a ladder for people to climb up and down.

Below the tower is a newly built red brick house, which is surrounded by a circle and includes the entire bottom of the tower.

The room is filled with a bunch of equipment that is incompatible with the current era. The most eye-catching thing is the circular iron cage about ten feet in diameter placed in the center of the room.

At this time, Zhang Wei was standing in the center of the iron cage, placing pieces of spiritual materials.

Zhang Wei placed several pieces of spiritual gold, spiritual beads, spiritual wood, and even raw materials from the monster beasts, filling the iron cage to the brim.

Then Zhang Wei walked out of the iron cage and made final adjustments on a pile of crude instruments next to him.

Zhang Xiong, the elder brother, and Zhang Ping, the nephew, were watching from the side. For these era-changing equipment, they could only watch their younger brother (uncle) work hard, and they could not help in any way.

Zhang Xiong felt a little dizzy when he looked at the pile of instruments in front of him. He couldn't figure out what was in his brother's mind.

But he still asked: "Can this be used to refine the essence of heaven and earth?"

Zhang Wei shook his head while adjusting the instrument and said with a smile: "I don't know, but I have to try. I have a hunch that I am very likely to succeed."

Zhang Wei is not aimless. Based on the information he has read over the years and his interactions with Xiao Yunshan and others, Zhang Wei feels that he has a high probability of success.

The most important thing about the spiritual essence of heaven and earth is the ray of Taoist rhyme contained in it. This ray of Taoist rhyme comes from many sources, but the spiritual essence of heaven and earth is all born in various strange places.

This is mainly due to the spiritual veins occupied by the major forces.

In addition to the birth of spiritual veins, the birth of other spiritual essences living outside the world is often related to the region and surrounding environment where they are located.

For example, in the sea of ​​​​fire in the volcano, which is difficult for ordinary people to enter, it is possible to find fire spiritual essence; in the deep sea secret places, it is very likely to breed water spiritual essence.

The main reason why the thunder essence is hard to find is that there is no suitable place to gather the corresponding spiritual energy between heaven and earth for a long time and turn it into the rhyme of Tao.

Maybe Zhang Wei could try to charge the battery every day for hundreds of years to see how it goes, but that time is too long, even if Zhang Wei is young, he can't afford it.

So Zhang Wei remembered that when he was in Linglong Xianfang, the middle-aged cultivator who introduced him to the Heavenly Thunder Refining Method half-jokingly said that he would let Zhang Wei be struck by lightning to try to enter the Tao.

Even the "Heavenly Thunder Refining Method" records several cases of being struck by heavenly thunder and not dying, but instead nurturing thunder spiritual roots, and thus worshipping Yunya Xianzong and soaring into the sky.

This shows that there is also the rhyme of Tao in the heavenly thunder! It's just that the power of heavenly thunder is extremely violent, and even a Jindan cultivator cannot extract that wisp of the rhyme of Tao from the heavenly thunder.

If most cultivators are struck by lightning, they are more likely to die directly, so how can they have the ability to turn heavenly thunder into the essence of heaven and earth?

Only a few lucky people can turn this disaster into an opportunity, absorb all the Dao rhyme in the thunder, and turn it into the foundation of their own immortality.

And now, what Zhang Wei is doing is to do what ordinary people dare not think of, to intercept the Dao rhyme in the magnificent heavenly power!

And his confidence is the cage in front of him!

This cage had a resounding name in his previous life.

Faraday cage.

Although it is said that the Faraday cage is not absolutely safe, for example, the Faraday cage cannot protect against the counter-attack overvoltage caused by the increase in ground potential caused by the lightning current entering the grounding device, but it should be enough to deal with the current situation... right?

As for the spiritual materials in the Faraday cage, they are the carriers used by Zhang Wei to carry the Dao rhyme of the thunder system. What he has to do next is to weaken the power of the lightning and thunder through the magic weapon of the magic saint, and then infuse it into these spiritual materials.

This step depends on luck. If you are lucky, you will succeed in one go. If you are unlucky, then Zhang Wei can only experiment slowly.

Boom... Boom...

Seeing the rain outside getting heavier, the gloomy dark clouds turned the whole world into night, and only the blue-purple thunder that occasionally passed by illuminated the world for a moment.

Splits————

At this time, a soul-stirring thunder roar suddenly sounded outside, followed by a crackling sound. It turned out that an old tree was hit and was directly split by thunder.

However, Zhang Wei knew that the time had come!

"Here it comes!"

Boom————

Another thunder exploded, and under the effect of the lightning rod, a lightning bolt struck directly to the top of the lightning tower. The terrifying current was transmitted along the line, covering the entire Faraday cage.

In an instant, Zhang Wei and Zhang Xiong, father and son, only felt a whiteness in front of their eyes, and their vision was deprived by the electric light, which hurt their eyes.

Even with protection, the three of them still felt a little numb.

As the only one among the three who had the deepest knowledge of lightning power, Zhang Wei's perception was even clearer at this time.

In his perception, he seemed to have entered a brand new world at this moment. The concentration of lightning attribute spiritual power around him exploded in an instant, and even poured a lot into his body.

However, it was only a moment. This tide of lightning attribute spiritual power came and went quickly. When Zhang Wei's vision was fully restored, the rich lightning attribute spiritual power also disappeared completely.

And in the Faraday cage after the lightning current surged, at least half of the various spiritual materials carefully selected by Zhang Wei began to break.

It is conceivable that if Zhang Wei really stood in it, what would happen to him.

Zhang Wei couldn't help but be amazed, thinking: "It is indeed worthy of the thunder of the world of cultivation. It turns out that the knowledge of the previous life cannot be moved as usual..."

Just when Zhang Wei was disappointed, he suddenly caught a glimpse of a bright purple light from the corner of his eye. Zhang Wei immediately looked and saw that the surface of one of the spiritual woods had actually emerged with blue and purple lightning patterns!

However, this lightning pattern has not been completely formed and is fading at a speed visible to the naked eye.

"Not enough, we have to do it again..."

Boom————

Boom————

Another thunderbolt struck, and the familiar feeling came again, and this time the feeling was even stronger, so that Zhang Xiong and his son standing behind Zhang Wei felt a sense of paralysis.

"Get out quickly!"

After the vision was restored, Zhang Wei immediately shouted at the trembling appearance of Zhang Xiong and his son, and then pushed the two men out of the room.

Even though Zhang Xiong and Zhang Ping were worried about their younger brother (second uncle), they could only leave the house at this time to avoid holding Zhang Wei back, and prayed that Zhang Wei would succeed.

Boom————

Boom————

As if a switch was turned on, when the thunderbolt fell, one after another lightning bolt struck the lightning tower again and again as if it had found its target, and the dazzling lightning light almost never stopped.

Crack, crack———

Bang, bang, bang———

Pieces of spiritual materials and spiritual woods could not withstand the power of thunder and broke apart, and the demon materials on the monsters were directly carbonized.

The raging electric current was even destroying everything in the room, and several instruments that Zhang Wei had worked hard to make began to emit black smoke!

When fifteen thunders surged, only three pieces of spiritual materials that Zhang Wei had put into the cage were left, two pieces of spiritual gold and a piece of spiritual wood.

Each piece of spiritual material has several vertical and horizontal thunder patterns on its surface, like cracks, and it is constantly emitting a coquettish blue-purple light.

However, Zhang Wei felt a strong attraction in it, just like a person who wants to eat when he is hungry or drink water when he is thirsty.

Daoyun!

Yes, this is Daoyun!

It's just that these Taoist rhymes are still very superficial and cannot be regarded as the true essence of heaven and earth at all.

But this also shows that Zhang Wei’s conjecture is correct!

There is nothing wrong with his experimental ideas!

"continue!"

Thinking of this, Zhang Wei tried to seduce Lei Luoxiao again, but this time, he felt a sense of sluggishness.

After listening carefully, I suddenly found that the rain outside seemed to have become lighter...

"The spiritual stones have been used up..."

Thinking of this, Zhang Wei's expression was a little bitter. You must know that in order to prepare for the Longmen Tide, many of his spiritual stones were used to replace them with equipment. For this experiment, he invested all the remaining spiritual stones in his hand!

However, judging from the current situation, the production of Lei Lingcui still has a long way to go.

"Try again!"

Zhang Wei gritted his teeth and tried his best to use his spiritual consciousness to communicate with the power of thunder that was about to disappear, thinking of taking a gamble at the end!

What if it happens?

Boom————

Another bolt of thunder struck down, and this time the power of the thunder and lightning was obviously much smaller. However, after the lightning that blocked his vision disappeared, Zhang Wei found with embarrassment that the last three pieces of spiritual material also shattered...

Gan!

Didn't this experiment gain anything except experience? !

Zhang Wei punched the instrument in anger, and the surface made of fine iron instantly sunk into a pit. As the instrument was damaged, a residual electricity instantly poured into the cage.

Then, Zhang Wei was surprised to find that the ground scorched by lightning fluctuated, as if a stone was thrown into the calm water, causing ripples.

"Um?"

Zhang Wei was stunned, walked to the cage, squatted down, stretched out his hand and touched the ground.

"This is……"

Zhang Wei's eyes suddenly widened and he looked at the layer of black sand on the ground in disbelief.

Is this...iron sand?

"Is the iron in the ground brought up after being electromagnetized by lightning?" Zhang Wei murmured, but suddenly thought of the strange appearance of the iron sand after the current surged through.

"wrong……"

Subconsciously, Zhang Wei grabbed a handful of iron sand, and with a crackling sound, as Zhang Wei released the electricity, the iron sand in his hand seemed to be alive, dancing in Zhang Wei's hand.

Zhang Wei's eyes widened, and then, the electricity stored in the three major dantians was released one after another!

Wow————

After the current surged through, the iron sand under Zhang Wei's feet automatically gathered towards Zhang Wei's body, flying around him like an elf.

Then the electric light burst out from Zhang Wei's hand, and the Yang Lei curse seal was activated. The iron sand around him quickly gathered, adhered to Zhang Wei's wrist and extended outwards, following the direction of the release of Yang Lei, turning into a winding A long knife with "black flame"!

Then Zhang Wei swung out violently, and the black flame instantly extended several feet in length, cleanly crossing the wall of the laboratory.

then……

Click————

The wall slowly slid down, and then crashed to the ground, splashing mud all over the ground, turning Zhang Xiong and the two waiting outside into mud monkeys!

Zhang Xiong wiped the mud on his face, looked at the neat and smooth cross-section, and then looked at Zhang Wei who was playing with black iron sand in the room, and asked: "Zi... Zijie, did you succeed?"

"No, but it hasn't failed. We still need to continue experimenting!"

Zhang Wei said, waving his hand at the same time, and all the iron sand flew into his mustard bag.

In the past, Zhang Wei could also use electricity to control a series of metal objects such as iron sand, but that required a lot of electricity, and it was completely uneconomical to install Magneto to play with metal. He could only use electricity-magnetized magnets to change his battery to improve his battery life.

But only this time, after being smelted by Tianlei, Zhang Wei found that he could move half a square of iron sand with only a small amount of electricity, and then play with it into various tricks.

This can no longer be regarded as simple iron sand, but should be regarded as a magic weapon!

It can be seen from the performance that the sand-iron sword formed from these iron sands is not inferior to the second-level magic weapon in sharpness, and it is even more weird and changeable. It can be regarded as a strange magic weapon.

And that's not all. After all, these iron sands have their own magnetism, and the magnetism is very strong, but they can be easily pried by themselves.

Electricity can generate magnetism, and magnetism can also generate electricity. If used properly, the iron sand can also recharge itself!

However, this will inevitably consume the magnetism of the iron sand, causing the iron sand to slowly return to mortal matter.

But this does indeed add a hidden energy source to Zhang Wei's back, greatly increasing his combat endurance.

According to Zhang Wei's estimation, if the magnetic force of this half square of electromagnetic sand was converted into electrical energy, it would be able to fill him at least dozens of times!

"Although I didn't succeed in creating the Thunder Spirit, I did get a good magic weapon and a refining method. It's not a huge loss."

Zhang Wei patted the mustard seed bag and thought to himself: "Let's call it You Electromagnetic Divine Sand..."

"However, whether you want to obtain more electromagnetic sacred sand or refine thunder spirit essence, you need more spiritual stones..."
