Because of the more and more runes mastered, it is no longer necessary to deliberately make a special electromagnetic circle to ionize the air, so as to immortalize the thrust.

The current rune array is much more refined, directly attached to the fitness, with the activation of the multiple rune array, it will generate a special dynamic magnetic field and geomagnetic field around it to form electromagnetic repulsion, so as to counteract the problem of gravity.

The forging speed of the flying sword can only be used incredibly fast, and it was originally known that Qiu Yiye had already done it and had to finish watching this magical flying sword forging process without sleeping for a few days.

However, the real situation is that after a mass of alloy was quickly melted, it quickly condensed into four different sword embryos, and while the sword embryos were condensed, they also left dense lines for inlaying runes.

The forging of the sword embryo only took two hours, and the process of adding the rune array was even faster, but in only two quarters of an hour, those very precious high-grade formation materials were melted, and quickly attached to those reserved lines to form many rune arrays.

Finally, after wrapping a layer of extremely stable platinum alloy on the outside, and completely covering those rune lines, the four flying swords were created in less than half a day.

"That's it?" When the three onlookers saw that Zhou Bufan had received the mental force field, they also asked in unison.

"Sort of, but it can't be used yet, the energy storage center in the flying sword has no energy, and these flying swords can absorb enough geomagnetic force."

"Brother Zhou, can't this flying sword use its own true qi to replenish energy?"

"Of course you can, you just need to hold the hilt of the sword and input the true qi, but the true yuan power of the sixth layer of qi cultivation is far from feeding the energy storage center in the hilt."

"How much True Yuan Power can that thing store?"

"It should be possible to store all the true yuan power of the twelve layers of Qi training."

"Brother Zhou, how much true yuan power is there in the twelfth layer of Qi training?"

"About 120,000 kilowatt hours."

"What's that 120,000 kilowatt hours?"

"Well, it's about the same amount of energy as 130,000 ordinary horses running for half an hour."

Zhou Bufan explained that several people suddenly realized, and they had an idea of the 120,000 kilowatt hours, but when they thought of the small sword hilt and the galloping of hundreds of thousands of horses for half an hour, they suddenly felt a little incredible.

“…… Oh my God, it's unbelievable that so much energy can be stored in this small hilt. Yuechi, who came back to his senses after a long time, said with infinite emotion.

"Don't make such a fuss, if you release all the mass energy contained in one of your hairs, it will be more than ten times greater than this energy." touched the other party's hair and said casually.

"It can't be." Yuechi is really imaginative, Zhiqiu and Qingfeng are also full of incredulity, and they really can't imagine how there can be so much energy in a hair.

"Yuechi, you can't directly deny the unknown, you have to make bold assumptions and be careful to verify, so that you can discover the truth of the universe, if you deny all unknown things from the beginning and don't explore and verify, then human beings will not be innovative? Development will also stagnate......"

Leaning lazily back in that simple rocking chair? Explaining some basic knowledge of modern science, how many people listened to it with relish? But it seems to be heard as a myth.

In this regard, Zhou Bufan can only express his helplessness? It's not that I want to teach these scientists to be the world, but this immortal search is actually a process of constantly exploring the unknown? So it's really important to be open-minded.

Otherwise, those who encounter a little bottleneck or something will only know how to drill the horns of the bull, and finally be completely trapped by that bottleneck.

——

Time is ticking by? Unconsciously it's still nightfall? After dinner, if the moon pond and Qingfeng are usually escorted by Zhiqiu Yiye, they will go back to their residence in the city.

It's just that today I have newly obtained a flying sword with an artifact, and the flying sword is replenishing energy in that special formation? Don't want to leave this magical flying sword? So I stayed in a makeshift camp in the wilderness.

At the unanimous request of several people, Zhou Bufan finally ended the popularization of scientific knowledge and began to explain the details of the functions of flying swords and how to control them.

"These flying swords have a total of three large combination arrays and four small combination arrays, the large array is to provide a flying magnetic repulsion array, an air breaking array to weaken air resistance, and a storage array that automatically absorbs radiation and geomagnetic energy and stores energy storage ......"

As he was talking, Yuechi handed over the brewed tea, took a sip and continued

"That small array is a solidification array used to strengthen the sword body? Easy to step on and control the miniature space confinement array, and there is also a lightning array for combat? When encountering an enemy, it can unleash a bolt of lightning to damage the enemy, and finally an air power array to assist in accelerating flight. ”

"Brother Zhou? What we want to know is how many people this flying sword can carry, how fast it can fly, how far it can fly, how high it can fly, and how high it can fly. ”

Seeing that Zhou Bufan always doesn't pay attention to the point? Yuechi also pulled his sleeve to remind him.

"Huh? The maximum theoretical load is about 300 catties? Of course, it will actually be a little lower, so standing on a big fat man of three hundred pounds, this flying sword will not be able to fly, and the flight speed is indeed not fast. ”

"It won't be slower than my chasing horse, will it?" Zhiqiu Yiye asked curiously.

"That's not it, although this flying sword can only fly about 400 miles in an hour, it is still a lot faster than a horse."

"Can you fly 400 miles in an hour, is it called slow?"

"Of course it's slow, but the current conditions are limited, so let's use it." Zhou Bufan's answer made Zhiqiu very speechless, the Venerable Celestial Venerable in the division, the sword can only fly for four or five hundred miles for an hour, and this speed is still slow.

I really want to ask, the speed of many pieces is called fast, but I was pulled down by the breeze next to me and immediately shut up.

Zhou Bufan didn't notice the small movements of the two, but his attention was involuntarily attracted by the moon pool leaning on his shoulder, which looked really charming under the reflection of the firelight of his face.

"Why didn't Brother Zhou say it?"

"Oh, yes, there is another problem, when this flying sword is carrying a weight of one hundred and fifty catties, the energy will be consumed when it flies for about five hundred miles, so it will land on the ground to recover its energy after flying five hundred miles."

"If you forget to detect the lack of energy, will it suddenly fall?"

"The amount of energy [black rock] does not disappear suddenly, when only the last layer is left, it will decay a little bit, the flight speed and altitude will automatically decrease, and the speed will automatically slow down a lot, which is easy to find."

"That's good, if you fly and suddenly fall down and die, then it's not worth lifting."

"Well, in fact, it is indeed not absolutely safe to foresee the flight, in case you are taken by some monster on top, a gust of demon wind will sweep you up and make you a lady of the village." casually ridiculed, but was punched by Yuechi.

"Don't talk nonsense, talk about this flying sword."

"Well, I know, I know, if this flying sword is exhausted of energy, I don't have the true qi to accelerate the recovery, and I don't have the support to assist in recovering the large formation, it will take a day and a night to fully recover the energy."

"As for the height, in principle, as long as there is a geomagnetic field, it can be borrowed, but with the increase in height, the geomagnetic force will gradually weaken, resulting in the weight of the flying sword will also weaken, and it is difficult to continue to climb when the weight of 150 catties reaches a height of about 30 miles."

"What if it's 95 pounds?" Yuechi also deliberately asked about his weight.

"You can probably climb more than 40 miles, but you must not try it, or you will get frozen popsicles."

"How can I be so reckless, okay, I understand the basic situation of this flying sword, sister let's go to sleep late at night." As he spoke, he directly pulled the breeze and went to a simple house in the distance.

"Brother Zhou, you have refined so many flying swords, let's go and rest quickly, I'll just keep vigil."

"Forget it, it's not raining anyway, so it's the same to sleep here." As he spoke, he casually covered himself with a blanket, and fell into a deep sleep in a blink of an eye, but after falling asleep, he had many bizarre dreams.
