Chug tug tug——
The propeller wrapped in the breeze talisman accelerates and rotates, generating wind force and driving the model aircraft to fly diagonally into the sky.
Li Ang raised his palm, released his telekinesis, and connected it to the fine gold thread on the model aircraft.
The fine gold wire tightened and contracted under the action of telekinesis, causing the flaps and ailerons of the upper and lower wings to expand, increasing the area and increasing the overall lift. It flew up and down in the air, going around and around.
It actually, really, flew...
The freshmen, who had already demonstrated their swords before, all raised their heads, opened their mouths, and looked at the flexible wood and silk model airplane in the sky in amazement.
Even Yang Yu and Li Wei put their palms in front of their foreheads in disbelief, blocking the sun and staring blankly.
Next comes the turn.
Li Ang gently raised his palm, and the fine gold wire responded immediately, adjusting the direction of the wings, driving the aircraft model to slowly turn, and draw a perfect arc in mid-air.
Sprint acceleration,
Slow down,
Li Ang only tightened or relaxed the four fine gold wires to easily control the flight speed and direction of the entire model aircraft
""Mozi·Lu Wen" says: Gongshu cut bamboo wood into a kite, made it fly, and did not set down for three days..."
A freshman whispered something, Xi Yangyu glanced at him and said calmly: "Essentially, the breeze talisman is used to drive the blades to rotate and generate wind force. When the spiritual power of the talisman dissipates, it will naturally fall.
What's more, it relies on a few fine gold threads to act as the soul of the sword and control its direction.
There is no need to hit it with a flying sword, as long as the mind power in the hiding place interferes with the connection with the sword, it can cause it to crash.
It’s a good idea, but I’m afraid it’s not practical.”
"Xi Siye can give it a try."
Li Ang turned to look at Xi Yangyu and said with a smile: "This 'Flying Sword' should not be afraid of interference."
"..."
Xi Yangyu glanced at Li Ang coldly. In front of Her Majesty the Queen and other Dr. Si Ye, he would not really release the disturbance of mind power to control the 'Flying Sword'.
Seeing that Xi Yangyu didn't take the bait, Li Ang curled his lips with regret, and actually put down his hands on his own initiative, cutting off the connection with the adamantine thread.
The model aircraft that was hovering in mid-air lost its guidance. The nose of the aircraft rose, and the wings dropped to one side beyond the critical angle. The overall lift dropped rapidly, stalled suddenly, and fell in a circle.
Many freshmen looking up below subconsciously exclaimed,
Fu Xuesi Ye Tantai Leshan raised his palm, ready to release the talisman to rescue this strange and interesting ‘flying sword’.
However, the next second, the tail rudder of the model aircraft, which lost its telekinesis control, automatically deflected with the airflow.
As a result, the aircraft model loses its heading stabilizing moment, causing the aircraft to slide inward in the downward spiral direction, and the upper and lower wings automatically return to normal under the action of the moment.
At the same time, due to the enlarged area of the horizontal tail, it is subject to greater air flow pressure, causing the aircraft model to automatically tilt forward, press the nose of the aircraft downward, accelerate and dive downward, and escape from stall.
Li Ang took a few steps back, looked at the direction of the model aircraft, raised his palm, and caught the model aircraft lightly and accurately.
This is the power of the Wave 2 aircraft - its structure is simple and its design is exquisite. Although its speed is slow and its flight height is limited, it has excellent maneuverability.
Once stalled, the pilot only needs to lower the control column, and the aircraft will automatically escape from the stall spiral state.
Therefore, in Li Ang’s memory of another world,
Only the Wave 2 aircraft was used as a trainer, liaison aircraft, ambulance aircraft, night bomber, and raider for novice pilots in the war. It is the second most produced aircraft in history.
Tear.
Li Ang regretfully pulled off the Qingfeng Talisman whose spiritual power gradually dissipated, and looked up at Emperor Yu who was silent.
"Leon."
Emperor Yu thought for a moment and asked: "How big can your flying sword be?"
Coming.
Li Ang smiled slightly. Emperor Yu Li Shun was a disciple of the mountain chief. He studied in the academy when he was still a prince. Although he was not a powerful monk, he could roughly tell.
The power source of the model aircraft is talisman paper, not the telekinesis commonly used by flying swords.
What is the biggest feature of talisman paper?
It can be stored, released at the right time, and... used by mortals.
What Emperor Yu and his ministers were thinking about were:
If the aircraft model is enlarged, can it carry people? Can it transport cargo? Can it be controlled by ordinary people, cross difficult terrains, and even travel thousands of miles in a day?
"Your Majesty, it's hard for me to say."
Li Ang cupped his hands, and as expected, he saw wonderful expressions on the faces of Emperor Yu, Empress Yu, important ministers, and Dr. Si Ye, "Disciples are only in the Qi state at the moment.
The power of the written talisman is weakening and does not last long.
In order for the flying sword to fly, it can only be so big.
If you switch to the Xunyun realm, the power of the talisman written by the Zhuxiao realm talisman master will naturally increase significantly, and the flying sword can also be enlarged.
But other factors of Feijian must be taken into consideration.
As the saying goes, pulling one hair affects the whole body.
To enlarge the volume, reinforcement materials are needed.
Reinforcement materials will increase the weight.
Increased weight will slow down the speed...
The specific actual operation remains to be further studied.
But one thing is certain, this model can carry people when enlarged.
It can even carry ordinary people."
As soon as these words came out, the expressions of everyone including Xi Yangyu changed again, especially those generals - they came to the Academy today to accompany His Majesty on vacation.
When I heard the news that model aircraft can carry people, I immediately started thinking about it.
Can it carry people?
How many people can it carry, how far can it go, how much cargo can it transport, and can it shorten the supply line for foreign expeditions?
Before troops and horses move, food and fodder must go first. Logistics is always the first factor that determines the outcome of a war.
The 'Flying Sword' only uses cheap materials such as wood and silk cloth. Even if it is completely replaced with steel, it is still within the acceptable range.
As for Tantai Leshan, who has a PhD in Engineering and Fu Studies, his thoughts are different.
symbol.
The power source of the 'Flying Sword' in Li Ang's hand is the talisman. Even though the 'Flying Sword' is simple in shape, as long as it is covered with iron and replaced with a better wind talisman, it can be transformed into a real flying sword that can travel at high speed.<
/p>
More importantly, it can carry things and is very cheap.

If you store a dozen offensive talisman papers inside and control multiple flying swords to hit the opponent, the talisman master can defeat the enemy from a distance of 300 feet without having to worry about himself being damaged——
The sword master cannot put powerful talismans on the flying sword, because if the flying sword is damaged and the sword soul is damaged, it will also cause mental damage to the sword master.
The wooden model in Li Ang's hand does not have this shortcoming at all and can be used as a one-time powerful weapon.
This is an invention that can change the battle pattern of monks and even the war patterns of all countries in the world.
Tantai Leshan made an instant judgment and subconsciously wanted Li Ang to put away his flying sword, but the next second he looked around at the crowd, and immediately realized that there were too many important people present, and it was no longer possible to keep it secret.
"Huh..."
Tantai Leshan let out a heavy breath and shook his head helplessly. From the corner of his eye, he accidentally caught a glimpse of Su Feng, Ph.D. of Science, who heard the noise and got into the crowd.
"Your Majesty."
Su Feng's eyes were attracted by the model aircraft in Li Ang's hand, and he reluctantly saluted Emperor Yu, then hurriedly asked Li Ang: "Risheng, why is the upper wing of this sword designed to be flat instead of flat?"<
/p>
"Dr. Su Feng, I call this part the wing. The wing is designed to be streamlined and flat, which is beneficial to reducing wind resistance and increasing lift."
"Wind resistance, wind resistance?"
Su Feng instantly understood the meaning of the word and immediately asked: "Is it the same as the design of the boat bottom into a fusiform shape?"
"That's right, the bottoms of most ships in the world are fusiform, and few are square - because a square bottom will resist the current, making the hull difficult to maneuver. The principle of wind resistance is also roughly the same."
Li Ang and Su Feng discussed and found that the latter already had experience-based understanding of concepts such as speed, acceleration, force, air pressure, pressure, gas density, viscous fluids, flow fields, vortices, etc., and his thinking was quite quick, and he could draw inferences from one example to other cases.
.
The rest of the people soon couldn't understand the conversation between the two,
When Emperor Yu had to interrupt, Su Feng's eyes were still shining, muttering to himself "ship propeller blades", "flowing boundary layer", "wind tunnel" and other words.
"Okay, there are still students waiting."
Emperor Yu turned to look at the forging workshop. The remaining freshmen in the workshop had prepared their own swords, but under Li Ang's background, they all looked so... monotonous.
A group of people including He Fanshuang, Ji Linglang, Qiu Feng, Li Leling and others forged the flying sword, although the quality of the flying sword was not inferior to Pei Jing's Canghai Sword.
This inspection course came to an end. As soon as the class ended, Li Ang, Doctor of Science Su Feng, Doctor of Engineering Tantai Leshan and others were invited by the palace servants to inquire about politics.
What Emperor Yu asked about was naturally about the aircraft. He hoped that the academy could do more research and the expenses would be borne by the Yu State court.
Li Ang pushed the matter to Su Feng and Tantai Leshan without hesitation. A real aircraft needs a more powerful engine and a more reasonable layout.
This research consumes too much time and energy, and will seriously slow down Li Ang's own practice progress.
On the other hand, Li Ang also wanted to see what kind of sparks the combination of talismans and aerodynamics could produce.
‘Three hundred years since the academy was founded, countless smart minds have been born. However, most of their energy was used to pursue the path of talisman, magic, sword, mind, and body.
In other words, the Academy has lit up another technological tree.’
Li Ang thought silently: "Different starting points of the technology tree will lead to huge differences in scientific and technological achievements.
Just like in the memory of another world, human civilization finally chose electricity instead of steam power."
Maybe, the doctors from the academy can research something new.
At the end of the political inquiry, Emperor Yu wanted to reward Li Ang with something, but after much deliberation, he still rewarded him with gold and silver in a vulgar way - there was nothing he could do if he didn't reward money.
Li Ang's age determines that it is inappropriate to reward him with a title now,
And the posthumous gift to Li Ang's parents is too... conspicuous.
The wood that is beautiful in the forest will be destroyed by the wind. The matter between Jun Qianzi and the assassins of the Southern Zhou Dynasty has not yet been resolved.
As for the marriage grant... Judging from Emperor Yu's expression, he may have had this idea, but he still didn't say it out loud this time.
The noble daughter of the Li family is really getting married. It’s hard to say whether it will be a marriage or an enmity.
Su Feng, Tantai Leshan and others respectfully sent Emperor Yu off, and Li Ang also returned home after completing the afternoon course.
Today it can be said that Qin Shihuang touched the electric wire - he won (win).
Not only was Xi Yangyu so shocked that he almost couldn’t get off the stage,
I also set up a personal setting for myself. In the future, I can naturally use a self-destructing aircraft equipped with talismans as a long-range attack method to prevent the enemy from getting close.
If you are not touched by others, you will naturally not expose the fact that you have Mosi.
In addition, he received 500 points, a gold and silver reward worth 5,000 guan, and a patent for the aircraft.
Five hundred points is already a lot of credits. If you save another hundred points, you can exchange them for precious metals such as orichalcum and black iron.
I don’t know what changes will happen after Mo Si is swallowed.
