……

Bai Yunpan sat on the ashlar stone and looked at the slowly disappearing image in the bronze mirror, a little helpless, and cut off the communication before he could tell where Uncle Xuanqing was, so where did he go to help Xuanqing!

"Alas! Forget it, I'll have to go back and pack my things later! I'll ask later! ”

"Now let's test the power of the Lightning Rush Fist first!"

Speaking of which,

Bai Yun shook his head, abandoned the distracting thoughts, and held his right hand in front of him, and suddenly blue-white thunderbolts slowly appeared in his hand, and he kept trying to poke out, but he was restrained by an invisible force to prevent it from escaping.

He raised his palm to his eyes and looked at it carefully, muttering to himself:

"The thunder and lightning seem to be several times stronger than a month ago, but I don't know how powerful it is!"

When I think of it, I have to try it,

Looking at a pine tree ten meters away the thickness of an adult's wrist,

Several electric arcs the size of chopsticks converged into a stream of thunder and lightning the thickness of a baby's arm in Bai Yun's hand.

With a wave of his hand,

The thunder shot away like an arrow from a string.

The speed of thunder and lightning is very fast,

It's so fast that it's almost impossible to react,

As soon as the lightning came out of his hand, it had already crossed a distance of more than ten meters, hitting the pine tree as thick as a baby's arm.

Bang~

The place where the lightning struck was suddenly blackened and sawdust scattered.

Click~

The pine trees fell in response,

Seeing this, Bai Yun struck another thunderbolt on a tree with a bowl mouth,

This time, however, it failed to break it, only blasting a hole the size of a baby's fist in the trunk of the tree.

Although the tree crumbled in the wind, it did not fall.

"It seems that the current lightning is not very high for the physical damage of unrestrained!"

Bai Yun shook his head, such a powerful thunderbolt obviously couldn't satisfy him.

"However, I didn't expect the Lei Fa I just cultivated to be very powerful at first."

After all, you can't expect the introductory thunder method you just mastered to be able to destroy a mountain with a single blow, and it has the power to destroy the world!

This... Unrealistic.

Although the damage to the entity from this grenade method was not strong, he had expected it for a long time, and he was not disappointed.

I also thought of a solution for this, that is, to use lightning as an energy source, use metal as a shell, and use the ampere force generated by the electromagnetic field to accelerate the metal shell, so that it can reach the kinetic energy required to hit the target, and the traditional gunpowder driven cannon, the electromagnetic cannon can greatly improve the speed and range of the projectile.

In the 21st century, the electromagnetic cannon can accelerate a 3-gram metal projectile to 11 kilometers per second, and a 300-gram projectile to 4,000 meters per second.

You must know that the firing speed of ordinary artillery is only about 0.8 kilometers per second, and the firing speed of rifle bullets is only about 1 kilometer per second.

The electromagnetic gun can achieve ultra-long-range strikes and can hit targets up to 200 kilometers away.

With such a powerful skill, as long as he masters it, even if his thunderbolt doesn't have such a high power now, he can still walk sideways in this era.

And it's an ability that can grow, the higher the power of the lightning, the larger the projectile can be launched at a faster speed, and the more powerful it is.

Unfortunately, in the 21st century, there is no small energy storage device that can provide the high energy density required for electromagnetic guns, and if the development of batteries had not been delayed, all countries would have put this weapon on airplanes and naval warships.

Even the electromagnetic railguns in the space-based weapons envisioned by the United States are to deploy 100 railguns in orbit at an altitude of 2,000 kilometers in space, accelerating the shells to a speed of 25 kilometers per second to intercept intercontinental ballistic missiles in the ascending stage.

This weapon has a very high ceiling, and as long as the quality and energy of the projectile increases, it can be upgraded from an electromagnetic rifle to an electromagnetic cannon and an electromagnetic railgun mounted in space orbit.

This series of ideas fell through the cracks because there was no small energy storage device to provide enough energy for the electromagnetic gun, leaving it in the experimental stage and unable to fight.

But none of this is a problem for Bai Yun, because he is a mobile battery himself, and as long as his mana is not exhausted, he can use this ability at any time.

Of course, all this can only be achieved on the premise that he has mastered electromagnetic technology, otherwise everything is just empty talk.

Thinking of this, Bai Yun dissipated the thunder and lightning in his hand and took out a handful of things that had been prepared long ago from his arms, a total of ten pieces of iron in the shape of a bullet the size of a tail finger, which was the projectile he intended to use for experiments.

Clamp the projectile with the index finger and middle finger, and the lightning extends two currents from the upper and lower ends of the bullet, and the mana forms the barrel to make the bullet travel in a stable trajectory.

Everything is ready to go,

Bai Yun's expression was serious, and he ran the lightning and thunder fist with all his might, and the huge current flowed through the bullet body from the upper guide rail and then back from the lower guide rail.

Shout~

When a near-inaudible sound sounded, the projectile in his hand had long since disappeared.

Scattered the thunder and lightning in his hand and looked at the direction in which the projectile was shot, but because the target was too far away, Bai Yun couldn't see it clearly, so he could only walk over to know how powerful it was.

The toes touched the ground, and the whole person swept towards the landing point of the projectile like an arrow from the string.

The speed of the white clouds is very fast,

In a moment, he had come to the place where the projectile hit, and watched a fist-sized hole in the trunk of the big tree that could barely be enclosed by the two hugs penetrate,

Bai Yun went around the back of the tree and followed the trajectory to find the projectile that penetrated the trunk of the tree, hit the stone not far away, and left a two-centimeter pit in the stone before stopping.

Stretched out his right hand and rubbed it on the stone for a moment, before pulling out the projectile with force, looking at the projectile that was deflated and could no longer see what it looked like.

The corners of Bai Yun's mouth rose slightly, revealing a satisfied smile.

The projectile that was fired spanned more than 2,000 meters and pierced a large tree hugged by two people, and after it could make a two-centimeter crater in the stone.

Such power has greatly exceeded Bai Yun's expectations, although the ceiling of the electromagnetic cannon is very high, but he has just tried to have such power, how can Bai Yun not be satisfied.

"Alright, the experiment is over, let's stop for today! I have to go back to the master and ask Uncle Xuanqing where he is! ”

After speaking, Bai Yun jumped and rushed towards the Nine Heavens Ten Thousand Blessings Palace.

……

In less than a cup of tea, Bai Yun returned to Huayang Temple, and when he opened the door, he found that the master was not in the view.

Bai Yun thought for a moment and knew where the master would be at this time, so he closed the door again and came to the Yuan Fu Guan where the real person in charge of the sect was.

Sure enough, as soon as I entered the Yuan Fu Temple, I saw the master Yuanchen Zhenren and Master Xuanxin sitting in it, chatting with each other.

Both of them stayed in Maoshan for a long time, and Bai Yun only noticed Bai Yun's arrival when he walked into the hall.

"Master, Master!"

Bai Yun stepped forward and saluted respectfully.

The master looked at the disciple in front of him, stroked his beard and nodded, seemingly quite satisfied.

And Xuan Xin seemed to be a little puzzled as to why Bai Yun came here, and wondered: "Didn't you rush to help your Uncle Xuanqing as soon as possible?" Why are you here? Should a manly man say goodbye like a woman? ”

Secretly said, when did my apprentice become such a mother-in-law?

"Master, you forgot to tell me where Uncle Xuanqing is!" Faced with Master's question, Bai Yun replied truthfully.

"Ahem~

Xuan Xin coughed lightly with a little embarrassment and said:

"Didn't I just say that?"

"Didn't say it!" Bai Yun replied definitely.

"Alright! According to the news he came back, he said that he was in Wenxian County, and he had been injured and hidden, you have to arrive as soon as possible, otherwise I am afraid that he will not be able to survive. ”

"Yes! Master! I'll go back and pack some things and I'll be off right away. ”

"Uh-huh......! Go ahead! ”

"Bai Yun, wait a minute!"

Just as Bai Yun turned around and was about to leave, Yuanchen Zhenren stopped him.

Bai Yun turned his head and looked at the master:

"I don't know what else the master commands?"

Yuan Chenzhen's gaze stopped at Bai Yun, he was also very curious about the apprentice in front of him,

How could a person think of simplifying the Heaven Shaking Returning Array to transform the aura and break through to the Foundation Building Realm in just one year, you must know that the entire cultivation world has not seen such a young Foundation Building Monk for many years.

"You refined that round mirror? How difficult is the refining? Can it be refined on a large scale? ”

This round light mirror is inspired by mobile phones, based on round light technology, can do video communication, send messages, video, and real-time positioning and other functions, it is not difficult for him, but he does not know whether others are difficult or not.

After Bai Yun pondered for a moment, he stretched out his index finger to draw a circle in the air, and used the circular light technique to display the rune prohibition required to refine the round light mirror as a two-dimensional model.

"It's so difficult that I think it's okay! I just don't know what you guys think? ”

Yuanchen Zhenren and Xuan Xin looked at the dense rune prohibition in the air, and immediately felt their scalp tingle, and couldn't help but sigh how to engrave such a large and complex rune prohibition on a bronze mirror?

The two of them had not worked hard together on the refining weapon, and now their heads hurt when they saw this rune.

"Ahh

Or find a professional to practice!

Yuanchen Zhenren looked at it carefully for a while, although he was not very good at refining weapons, but he had practiced for decades, and he could be regarded as well-informed.

He seemed to recognize the function of some runes, so he pointed to some of them and said, "Isn't this piece the rune of the Yuanguang Technique?" In addition to this part of the Circle Light Technique, how can there be so many rune prohibitions? ”

Hearing this, Bai Yun looked at the side of his finger:

"Oh...! Because in addition to the circular light technique, I have also added real-time positioning, sending messages, video recording, and other functions on it! ”

"What is real-time location? What does it do? ”

This time, Yuanchen Zhenren was even more confused, he could understand the recording and sending messages, but he didn't know what this real-time positioning was!

Bai Yun didn't speak, because he knew that it would be difficult to explain clearly for a while, so he took out the bronze mirror from his arms and entered the mana, and said to the bronze mirror: "Request the position of Master No. 2 Mirror!" ”

As soon as the words fell,

Xuan Xin took out the bronze mirror in his arms, and after inputting the mana, a voice recorded in advance by white clouds sounded in the bronze mirror:

"No. 1 Mirror Baiyun requests real-time location, is it authorized?"

Xuan Xin glanced at Bai Yun a little overwhelmed like an old man just starting to play with his mobile phone, and only when he saw Bai Yun nodding tentatively: "Authorize!" ”

Bite...

Two spots of light appeared next to each other on a rough map in the bronze mirror in his hand.

Xuan Xin could vaguely see from the mountain range trend on the map that this was the terrain of Maoshan Mountain.

Yuanchen Zhenren and Xuanxin stared at the bronze mirror for a long time before they raised their heads and looked at Bai Yun ecstatically:

"That's what you call a real-time map?"

Bai Yun looked at the expressions of the two of them with some incomprehension, this function will be rotten in a hundred years, and it is nothing special! Disappreciatively, he replied, "Yes! It's a pretty ordinary feature! ”
