Under the cover of night, Jiang Mu left the head of Lingyu on the Tinglei platform, laid down a ban, and made it look like he was in retreat and did not disturb.

Then, he wrapped his whole body in liquefied dark iron, took out a hidden spirit rune, and flew up to the clouds silently, leaving from a flaw in the mountain protection array.

Well, this mountain protection array must be replaced, otherwise anyone can enter the mountain gate of the Floating Cloud Sect.

Looking back at Fuyun Mountain again, Jiang Mu slowly injected the sword yuan force into the flying sword, and in an instant, this flying sword was like one of his arms, and there was no delay at all.

With this alone, his sword yuan power was much more than mana.

It's just that there is no light flowing above the flying sword, and there is no sword aura rushing into the clouds, black and dull, not at all inconspicuous.

However, if you use your divine mind to sense it carefully, you will notice that after the sword force is injected, the flying sword is not unresponsive, but there is a force circulating inside, so it forms an inward pulling force.

Therefore, it is not that it does not emit light, it is not that it does not have sword qi, but it will devour the light and converge the sword qi.

This point has been proved when Jiang Mu manipulated the flying sword to continuously pull upward.

Although he didn't have a natal flying sword before, he had also seen it, the kind of natal flying sword that was driven by mana, when it was excited, it would form a brilliant light, and at the same time, there would be extremely obvious sword qi fluctuations, the faster the speed, or the more complex the flashing and moving, the more terrifying the sword qi fluctuations would be, and even form a terrible sword howling cloud, which could be sensed hundreds of miles away or thousands of miles away.

Jiang Mu had also been fortunate enough to see the appearance of the old monster urging the flying sword to cross the sky, it was really a kind of whole sky exploding, the sun was falling on the world, and everywhere he looked, there was a dazzling rainbow, like a doomsday cloud!

And this terrifying sword qi calamity cloud can be sensed from tens of thousands of miles, if it is within a thousand miles, mortals will die, and within a few hundred miles, low-level immortal cultivators will also be seriously injured, and even the Yuan Infant Realm immortal cultivators dare not approach within dozens of miles.

Jiang Mu used to be extremely envious, but now he has learned to look at things from another angle.

The old monster can control the flying sword like this, so how much should the waste of mana and the consumption of mana be?

Even if their mana is profound, how many times can they release it?

"So far, I'm afraid I can't beat the old monster of the gods, no, don't even think about it, just the fact that the old monster can master the Dao is incomparable, the characteristics of the sword yuan force are introverted and economical, but it is not used to fight the law."

Jiang Mu warned himself in his heart that he could not forget his original intention.

At this time, the flying sword has been pulled up to a height of tens of thousands of zhang, and the wind is cold, and under real-time induction, a total of 5 wisps of sword yuan power need to be consumed before and after this step.

This loss is a bit large.

However, when the flying sword flies steadily at a fixed altitude, the consumption is visibly reduced.

Jiang Mu injected a wisp of sword power, and the flying sword could fly forward quickly and silently, and he calculated this speed, which was about five thousand miles a day, which was more economical than flying close to the ground.

However, as long as you choose to adjust the direction, you must inject additional sword power.

Next, Jiang Mu continued to inject sword yuan power into the flying sword, and in just a dozen breaths, the speed of the flying sword exceeded his previous flying magic weapon, the flying boat that could travel thousands of miles a day, and the injected sword yuan power at this time was 20 wisps.

If he didn't continue to inject it, these 20 wisps of sword yuan power would be enough to support him to fly out of 10,000 miles, or even more.

Converted, it is twenty spirit stones.

At the same distance, the price of using the teleportation array is 1,000 spirit stones, of course, that speed is much faster, and it can be reached instantly.

As for the use of the Flying Boat, the consumption of traveling thousands of miles a day requires about 100 spirit stones.

Of course, before the aura of heaven and earth has not disappeared, this consumption of mana can be recovered with only a stick of incense meditation, and no one should take it seriously.

But in the era of the end of the law, this is very important.

Jiang Mu is still slowly accelerating.

When the sword element power injected into the flying sword reached 50 wisps, the flight speed was completely different, more than three times faster than the flying boat.

But this is not the point, but at this speed, the flying sword is still dark and heavy, and it will not bring up the slightest streamer, and the fluctuation of sword qi is only scattered in a radius of a few zhang.

This kind of concealment really surprised Jiang Mu, he didn't pursue how fast and strong the flying sword could be.

Saving, safe and concealed are the best choices.

Unconsciously, the flying sword had flown out for nearly a thousand miles, and there was a faint spiritual light in front of it, but it was passing by the mountain gate of the Iron Mountain Sect.

As the culprit who destroyed the Floating Cloud Sect in his previous life, Jiang Mu has been reborn for more than half a year, and he has to refrain from thinking about how to retaliate.

But passing by here at this time, the old hatred in his heart was inevitably aroused, so he stopped flying his sword and stopped to take a few more looks.

As a result, the next moment, a sword light swept up from more than a hundred miles away, heading towards the Iron Mountain Sect Mountain Gate, and that rough, irritable sword qi fluctuation was like a big catfish in a dung pit.

Jiang Mu wasn't a tricky and mean person, but he couldn't find a better description, especially after testing his own flying sword.

The speed of the opponent's flying sword was twice as fast as his flying boat, and the speed was about the same as that of the second senior brother Xu Yi, but the fluctuations of this sword qi were transmitted to a hundred miles away, which was a huge consumption of mana.

Almost one breath has to consume fifty spirit stones.

This distance of more than 100 miles, that guy has to consume a thousand spirit stones, if the aura is full between today and today, it naturally doesn't matter how he wants to toss, but if there is no aura, tsk, he has to scrap ninety percent of his ability.

His mind changed, Jiang Mu slowly rose to height, he had no intention of starting a war with the Iron Mountain faction for the time being, everything was based on the overall situation.

After more than twenty breaths, the sword light had already come to the front, and Jiang Mu was not found at all, but the other party did not have the slightest idea of entering the mountain protection array, but pulled the sword light and surrounded the mountain protection array of the Iron Mountain Sect for a week, and the strong sword qi fluctuations were so agitated that the mountain protection array was activated, and countless runes were like ripples, which looked very good-looking and majestic, in fact, this wave of heaven and earth aura equivalent to at least 5,000 spirit stones was consumed.

"It's him!"

Jiang Mu recognized the other party, it was Dong Yushu, the number three person of the Tieshan faction, and in his impression, he was a cultivator in the late stage of Jindan, and he was the same generation as his senior brother Yao Cheng.

In his previous life, it was this person who took the lead in leading the team to break through the Floating Cloud Sect.

At this time, when the enemies saw each other, Jiang Mu had to control himself not to blush.

I don't want that Dong Yushu to suddenly scream,

"He Fangxiao is small, dare to covet and peep at my Iron Mountain Sect Mountain Gate!"

Jiang Mu thought that he had been discovered, but not only was he not nervous in his heart at the moment, but his thoughts were clear, and he no longer hesitated, and with his divine thoughts, a full 500 wisps of sword yuan power were injected into the flying sword, and he only heard a buzzing sound, and with one sword, he crashed into the mountain protection array of the Iron Mountain Sect.

Oops, he forgot that he was not good at fighting in his two lives combined, and this attack that was supposed to lock on Dong Yushu actually failed.

"Boom!"

Attacked, the Iron Mountain Sect's mountain protection array erupted directly, and countless runes flowed aura, turning into mountains to lock on Jiang Mu in an instant, and smashing down with the momentum of wind and thunder!

At this time, Jiang Mu was really a little panicked, and subconsciously wanted to escape, but the flying sword was locked and suppressed by the mountain protection array, like an old cow trapped in a quagmire, and he couldn't break free at all.

In a hurry, he could only frantically inject sword yuan force into the flying sword, but the force was too strong, and in an instant, the originally dark and heavy, restrained sword qi, like an old cow, suddenly shined at this moment, and a terrifying sword qi cloud exploded, not only destroying the mountain protection array like a decay, but also flying out like lightning with a terrifying sword qi Changhong!

However, because Jiang Mu still didn't control the direction, this sword rushed towards the main peak of the Iron Mountain Sect.

He only faintly heard a roar, as if someone was ......

In the next moment, more than half of the hundreds of feet high mountain was cut off!

The grass, trees, rocks, buildings, or living creatures on the mountain were all shocked and killed by the fluctuation of sword qi, even the mountain peaks that were cut down.

Even so, this flying sword still had unabated momentum, and it rushed out hundreds of miles away in a few breaths, until Jiang Mu reacted and hurriedly withdrew the sword yuan power, otherwise I was afraid that the next one to suffer would be the Mingshan Sect Mountain Gate.
