In order to kill Li Qianqian, all night, Du Bian was racing against time.

After Xuan Qi awakened, he immediately entered the study of the Vortex Sword Technique.

The original cheats about this set of swordsmanship were gone, but it took Great Grandmaster Ning Zongwu half an hour to rewrite the entire cheats.

After Du Yan saw it, he sighed again.

This is really not a set of swordsmanship, but more like a combination of science and martial arts.

The core point is to control the oscillation of the internal force of Xuan Qi and create an energy vortex.

The whole process is really complicated to the extreme, and the whole cheats book is not like a martial arts cheatbook, but more like a collection of mathematics and physics.

There are thousands of various bands and various mathematical formulas.

This kind of cheats makes people's scalps tingle at a glance, and it can be said that in addition to Du Bian, there are definitely not many people in this world who can understand this cheats.

For Du Bian, it is not difficult to understand this cheat, but the difficult thing is to master it all and actually fight it.

Because even if the whole set of swordsmanship is wrong in one link, a certain piece of data will be wasted, and it will not be able to cast an energy vortex at all.

Fortunately, there is a dream system, otherwise even with Du Chang's comprehension, it will take at least a few months to master this set of cheats.

After quickly flipping through the entire cheatbook, Du Bian closed his eyes and entered the dream in the fastest time.

Suddenly, Du Chang seemed to be a different person.

The development of the brain domain has increased tenfold, and the previously obscure and difficult cheats have become simple again, and the full two hundred pages of cheats can be completely memorized in just one day in the dream realm.

This so-called vortex sword technique is not a one-move style at all. It's about understanding the principle before you can put it into practice.

The legendary trick of winning without a trick is shown here in an alternative way.

Next, Du Yan realized in a dream.

The process is very long, a few hours, dozens of hours, a few days......

Until every band, every formula, and every principle are fully understood, then gather their own tendons and veins, and figure out how to use it.

In the dream, for six days and six nights, Du Chang completely comprehended this set of "Vortex Sword Technique".

Next, the actual combat drill begins.

It's been countless failures again, because the whole process is too complicated, it doesn't look like a set of swordsmanship at all, it's more like a project, or a program, the cheats are software, and the body is hardware.

Even if one detail is wrong, it won't succeed.

Tried over and over again.

Dozens, hundreds, thousands, tens of thousands......

About five hundred times, Du Bian had already successfully performed this set of "Vortex Sword Technique" and successfully created an energy vortex.

But it's far from enough, because his Xuan Qi is too weak, so the energy vortex created is also very small, and it can't include two people at all, and it is likely that it can't attract thunder and lightning in the sky.

Xuan Qi cannot be improved, so it can only improve the utilization rate of Xuan Qi and minimize waste.

After countless adjustments, streamlining, transformation.

Even later, Du Bian made drastic changes to this set of cheats.

Eventually, he was finally able to use his weak Xuan Qi to create a vortex that was more than twenty meters tall and more than three meters in diameter.

In this way, Du Bian and Li Qianqian can barely be wrapped.

Not only that, but it should also be enough to draw thunder and lightning from the sky.

Du Bian opened his eyes and woke up, and it was almost dawn at this time.

"How?" asked Grand Master Ning Zongwu.

Du said: "It's done." ”

Ning Zongwu's eyes lit up, and then he handed over a sword.

This is a Xuantie Sword, which has been specially handled by Grand Master Ning Zongwu, and has a powerful magnetic nature.

Du Chang took the sword, took a deep breath, and then began to use the "Vortex Sword Technique".

This set of swordsmanship has no moves at all, just holding the sword and drawing a circle.

Du Chang's faint Xuan Qi was continuously released through the Xuantie Sword, forming a whirlpool with layers, like a tornado.

It's just that this whirlpool can't be seen or touched.

Because his Xuan Qi penetrated the Xuan Iron Sword, the energy released was also full of magnetic power.

Just a few seconds later, a vortex of magnetic energy two meters in diameter and twenty meters in height formed, constantly spinning, constantly devouring the air around it.

Ning Zongwu closed his eyes, and he could clearly feel this energy vortex.

There is no doubt that Du Chang's vortex sword technique is finished.

Suddenly, he took a long breath and said, "Geniuses can really do whatever they want. ”

He couldn't help but be amazed, he couldn't help but sigh.

This "Vortex Sword Technique" is not a real sword technique, but it is more difficult, and it is more than twice as difficult.

That kind of complexity and profundity is not comparable to normal swordsmanship at all.

Converted to other people, he couldn't even understand this set of cheats, but Du Bian still mastered it overnight, or in the middle of the night.

"Master Ning, is the secret gold powder ready?" Du Bian asked.

Ning Zongwu took out a porcelain bottle, which contained about dozens of milliliters of secret gold powder. Du Chang discovered that the secret gold powder was actually transparent, and it looked like water was flowing.

"This secret gold is extremely precious. Ning Zongwu said: "It is specially used for sword veins." ”

In addition to being sharp and tenacious, the most important thing for a superb sword is that it can transmit sword qi. Ordinary metal can also conduct internal force and transform into sword qi, but it is very wasteful.

Just like iron, it conducts electricity, but the resistance is very high.

And this kind of secret gold is like a superconductor on the earth, which can perfectly transmit the internal force of Xuan Qi, and the waste is not more than ten percent.

Therefore, every superb sword must use this kind of secret gold, and half a tael is enough.

It is also a near-perfect conductor of electricity, because it is extremely thin and transparent, so it is completely invisible to the naked eye, and it will drift away when the wind blows gently, once it is filled in the vortex energy array, then the entire energy array will become a huge space conductor.

However, this thing is too precious to allow Du Bian to experiment.

"Now everything is ready, only the thunder and lightning are owed. Grand Master Ning Zongwu said: "If you don't know when and where there will be thunder and lightning, then everything will be wasted." ”

Du Bian smiled: "I'll ask the immortal to see if he will tell me." ”

With strong expectations, Du Bian closed his eyes and entered the dream again.

......

The dream is different from what Du Chang imagined.

Not on the top of a mountain somewhere, but on a boat on the sea.

The weather conditions are very complicated, and the sun is setting in the distance, and half of the sun has already set below the surface of the sea.

And here the sky is full of dark clouds, and the whole dark cloud is like a whirlpool, which has very significant characteristics.

And there is an island in the distance of the sea, which is all stones, and it is colorful stones, without any vegetation.

Du Chang knew that this was an island and reef.

"Hmm, hmm......"

At this time, there was a cute dolphin cry near the coral island.

A few seconds later, a dolphin leapt out of the water.

Meanwhile!

"Bang Bang Bang ......"

A bolt of lightning burst out from the dark clouds in the sky and slashed down.

This lightning came very suddenly, very suddenly.

The sun was setting in the distance, and there was a swirling cloud in the sky, but the clouds were not big or thick, and they did not look like the weather conditions that formed lightning.

But Du Chang knows that the ocean climate is ever-changing.

It's just that this lightning is not big enough, it can even be called very small, can it be killed by Li Qianqian?

Du Chang continued to wait.

However, there was no more lightning.

After the lightning struck, a few drops of rain fell, and then the swirling clouds simply dispersed.

In other words, there is no second lightning bolt in this dream.

Du Bian hurriedly memorized all the key information.

Lightning time: Around half past six in the afternoon, the sunset is halfway down the sea.

Lightning occurred near a five-finger-shaped coral reef, below a whirlpool cloud.

Characteristics before the lightning strikes: Three seconds before the lightning strikes, a dolphin chirps on a coral reef, and then a dolphin mischievously jumps out of the water.

In other words, Du Bian must run the magnetic energy vortex in advance, and shoot the sword at the moment when the dolphin jumps out of the water.

The opportunity for lightning is fleeting, and there must not be a slight error, otherwise the previous efforts will be wasted, and death will be assured.

......

Du Chang woke up again, and it was already morning.

"How?" Ning Zongwu said, "Did the immortals tell you when and where there would be lightning?"

When he asked this, he thought it was a little ridiculous.

Immortal dreams have existed since ancient times, but the immortals dream tells when and where lightning will appear, which is also too ...... Bizarre.

However, Du Yan nodded.

Then he took a pen and paper and drew the contents of the dream.

On the sea, the sunset is halfway down, and the five-fingered coral islands and reefs not far away, the dolphins jumping, the whirlpool dark clouds in the sky, and the fine lightning that falls.

"Does Master Ning know where this is?" Du Yan asked.

Ning Zongwu said: "I know, this is Wuzhi Island, one hundred and ninety miles southeast of Lianzhou Mansion. ”

This location is quite famous, because of the special shape of these five-fingered coral reefs and their forced style, so many of the master's peak duels are held here.

"Maybe it's fate, maybe it's fate. Ning Zongwu sighed: "Twenty years ago, the first battle between me and Li Daozhen was fought on these five finger islands and reefs, and it is today. ”

Du Yan was stunned for a moment, maybe there is really a providence in the dark, someone should die in that place, hoping that person is a slut.

"Then it's decided, go to sea today, near the Five Fingers Coral Island and Reef, and kill Li Qianqian. Du changed his way.

Ning Zongwu said: "It's still too dangerous, although your plan is extremely mysterious, but even the slightest error will definitely die." Li Qianqian can kill you in an instant!"

Du Bian said: "Master Ning, this is a game with the god of death. Don't say that you are 60% sure, even if you are 30% sure, you have to do your best!"

Ning Zongwu looked at Du Bianliang for a long time and said, "Child, I believe that you are a person with great luck and will definitely be able to create amazing miracles." Such a mysterious killing game, using the right time and place, is just right to sacrifice Li Qianqian's life. ”

Du Bian gritted his teeth and said: "Yes, today I will kill the slut and sacrifice to the sky!"
