Perhaps those mysterious energy information that cannot be seen, touched, or perceived with the divine sense is a special form of legal manifestation, and sleeping and dreaming seem to be able to assist in understanding these information.

A few days have passed, and after absorbing a lot of information, after a few sleeps and dreams from time to time help to understand, I know something related to the rules of time and space.

Maybe in the long run, with the help of Qiankun Ding and the mysterious spearhead, one day you will be able to fully understand the rules of time and space, and then you will be able to travel freely through time and space, without being led by the nose like now.

It's another night of fragmentary dream fragments, but it's like an enlightenment, sorting out miscellaneous information, but there seems to be some flaws in this dream, and it may consume a lot of mental power, anyway, every time you wake up in the past few days is more uncomfortable than staying up for a few nights without sleeping.

It took a few minutes to slow down his mind before he regained a lot of mental power, and he habitually unfolded his divine sense and glanced around.

When no one disturbs to concentrate on expanding the divine sense perception, it can easily borrow the Qiankun Ding's mysterious energy field, and even expand the perception radius to two kilometers away.

It seems that Feng Qingyang is practicing the volley void again, of course, Ren Xing is also trying to exercise, but although his internal strength can also achieve the degree of volley void, the control is much worse than Feng Qingyang.

Therefore, although you can go to the sky, you will fall down from time to time, and the blue nose and swollen face of the fall will cause the onlookers to chuckle quietly, but the personality of the changed let me do not mind this at all, just patted the dust on my body, jumped up again and continued to trample the air to the sky.

There are also Xiang Wentian and the non-precepted monks who are also exercising, but they can barely step on the air three or four times to borrow power, and they can't go to the sky at all.

Of course, you can borrow power in the air three or four times, and the height of the jump and the distance of the vertical jump, of course, can be increased a lot.

As for the other little girls, because of the internal force is of course only for the sake of onlookers, they can't release their true qi at all, and if they want to really go to heaven, they have to work hard for at least ten years to be possible, so they can only watch others go to heaven with envy.

Of course, what they don't know is that in fact, Zhang Tiancheng has been using pneumatic thrusters in the past few days to make a flying sword weapon that can carry people, and he is going to give one to each person before leaving, which can be regarded as the last gift for everyone.

Retracted his divine sense, and floated up directly from the bed with a slight leap, the Northern Hell suit that was like a robot standing on the side dissolved in an instant, and it was equipped on his body in the blink of an eye, followed by a teleportation to the laboratory.

The dozens of WeChat pneumatic thrusters have completed the electroplating of the formation materials, carefully checked it, and determined that there is no problem with the formation that can make the air flow, so they put away the electroplating solution.

And the sword embryo of the flying sword on the other side has already been prepared, so there is no waste of time, and the final installation of this special flying sword that can be manned directly started.

This time, I made nine flying swords in one go, and I was going to give one to each person, and even that Zhu Houzhao would give one.

The basic material of the sword embryo is a carbon fiber plate with light weight and high strength, which is brought from the real world, and the comprehensive strength is several times higher than that of steel, and even in order to further improve the comprehensive strength of the flying sword, a layer of super alloy is wrapped around the outside of the flying sword.

In addition, in order to make it easier, these flying swords are all of the same size: the sword is 120 cm long, 12 cm wide, 3 cm thick at its thickest point, and weighs 4 kg, of course, after adding 5 micro pneumatic thrusters, the total weight should be about 5 kg.

The maximum thrust that five pneumatic thrusters can provide is 100 kg, so the theoretical load of the flying sword after the completion of the equipment is about 95 kg, and as for the speed of manned flight, it should be able to reach a speed of 400 kilometers per hour without afterburner.

This speed is actually almost the same as the original Northern Hell suit, of course, the formation materials are not bad recently, of course, the Northern Hell suit has also been transformed, and the pneumatic thrusters have increased by as many as four.

Two of them are still added to the shoe, the other two are connected to the palm of the hand through a portal, and of course these two are devices that can be replaced at any time.

As long as you change the position of the corresponding portal in the space backpack, it is a weapon when it is attached to a weapon, and it is a thruster when it is connected to a thruster.

With the addition of pneumatic thrusters, the sound barrier can barely be broken during afterburner flight, and theoretically, of course, the thrust of the thrusters can continue to be increased.

However, the current aerodynamic layout of the North Hells suit is not very good, the flight speed is too fast, and the vibration is very strong, even if the strength of the suit is very high, it will not be shaken apart, but the bump and vibration of the body is really unbearable.

……

Shen Nian was extremely proficient in controlling various tools, and quickly assembled pneumatic flying swords, a few points faster than the fully automatic mechanical arm, but in just half an hour, the nine flying swords were all assembled, and then a teleportation arrived in the square.

"Master, why haven't you gone to the palace today?" Seeing Zhang Tiancheng appear, Qu Feiyan ran to say hello as soon as possible, and several other girls also finished their workouts and came over.

"The swordsmanship of the adult is becoming more and more exquisite, and he can control so many giant Xuantie flying swords at the same time." Seeing Zhang Tiancheng surrounded by several very huge flying swords, he praised him from the bottom of his heart.

"This is not an ordinary flying sword, don't go, Lao Feng, send the flying sword, everyone who comes to see it has a share." Seeing Feng Qingyang and the others deliberately walking towards the distance, he hurriedly greeted.

"Brother Zhang is polite, the old man's method of controlling the sword with qi is really not good, so don't waste your Xuantie Sword."

"Old man, this is not an ordinary Xuantie sword, but a pneumatic flying sword, which can carry people and fly thousands of miles a day, do you really not want it?" As soon as Zhang Tiancheng's words fell, the wind cleared and suddenly turned back, and a vertical leap floated to his side.

"Is that true?"

"Of course, this flying sword can fly 1,600 miles in one hour."

The other few were originally not very interested in flying swords, because they were worse at controlling swords with qi, but when they heard Zhang Tiancheng's words, they were no longer calm, and rushed to Zhang Tiancheng's side in the blink of an eye.

"What the door master just said is true, and those who see it have a share?" The one who asked was the non-abstaining monk.

He thought that since he came to Phoenix Villa, he had always taken advantage, and he had taken advantage of too much to make this thick-skinned monk feel a little embarrassed.

He has neither the diligence of asking the sky to help take care of the construction of the villa in the villa, nor the talent to really participate in the heavenly plan, nor the few little girls who are cute and cute......

"Of course, you are also the honorary elder of the Carefree Sect now, and of course you have a flying sword to show the grade of my Carefree Sect."

"Thank you master, in the future, the big monk I will be the number one thug of the free faction, if anyone can't get along with the free faction, the big monk I will be the first to go first." The unprecepted monk patted his chest and promised, but Yilin on the side lowered his head in great shame, this father was really embarrassed in front of Brother Zhang. However, he found that a flying sword had floated in front of him, and Zhang Tiancheng also began to explain the use of this pneumatic flying sword, and he also held the hilt of this flying sword with a red face.

"Everyone runs your true qi to the palm of your hand, and there is an induction loop on the hilt of the sword, which will record the fluctuation of your true qi."

"My lord, this flying sword has always needed to be driven by True Qi to fly?" Narin asked, a little puzzled.

"Senior sister, you are really stupid, if you always need to be driven by true qi to fly, then how can the master say that you can fly more than a thousand miles in an hour, just like our little true qi, we have to fall down if we can't fly half a mile." Qu Feiyan answered first.

"Then what kind of power do you say this Qi Flying uses?"

"Of course, it's the infinite energy between heaven and earth, do you think that just this bit of our true qi can make Vajra Zhuo reflect and divert all attacks?"

Seeing everyone looking at him, Zhang Tiancheng could only nod and confirm Qu Feiyan's statement, there was really no way for this smart little apprentice, and he couldn't pretend to be forced if he wanted to.

Several people couldn't wait to input a trace of true qi energy on the flying sword, and the energy induction loop of the hilt quickly recorded the true qi fluctuation information, forming a special life field binding pattern. (True Qi contains unique life field fluctuations)

Of course, this binding is not meant to be bound forever, in principle, it can also be cleared by formatting the record data, and before the record data is not formatted, others can't use the flying sword that has been bound.

Of course, this flying sword can also be picked up and slashed, but it is very bulky and not easy to use, so this thing can basically only be a means of transportation.

Zhang Tiancheng quickly finished explaining how to control the flying sword, and everyone jumped on the flying sword with great interest, performing the flying sword that they had imagined countless times.

One by one, they are all masters who have mastered the internal force of true qi, and their reaction ability is extremely fast, and the flying sword is also equipped with an auxiliary balance system, so as long as they don't die on purpose, they don't have to worry about falling.
