Li Ang dipped some dew from the weeds on his thumb, raised his thumb to face the morning wind, and felt the wind speed, wind direction, temperature, humidity and other factors.
Everything is appropriate.
He turned to look at Yu Feiyu and said with a smile: "The special envoy can check this aircraft to make sure that no threads or talismans are used on it."
Yu Feiyu frowned slightly, took half a step forward, released his spiritual consciousness, and scanned the "work" shaped aircraft.
Indeed, as Li Ang said, the metal wires, masts, propellers, transmission devices, etc. on the aircraft are all made of ordinary metals and light wooden boards, which are not the best carriers of telekinesis.
As for the skin of the aircraft...
"Is this the skin of a raccoon rabbit?"
Yu Feiyu asked.
"It's paper made of raccoon and rabbit skin."
Su Feng nodded and said: "Peel off a layer of rabbit skin into five pieces, tan them, dry them in the shade, soak them in water and crush them, and fuse them with the red bamboo fibers to make a whole piece."
Bian Chenpei's eyes lit up and he immediately said: "The raccoon rabbit is a fourth-class monster. Materials made from its skin are naturally alienated materials and are considered contraband!"
"I'm afraid not."
Su Feng glanced at him and said calmly: "The raccoon rabbit paper is very light in weight and extremely tough. It will not be damaged when being torn or exposed to water.
It can be used as a high-quality leather armor lining, or as paper to record important information.
The raccoon rabbit paper that our academy used again in the third year of Zaiqian was the raccoon rabbit paper.
It is already a common item in the Yu State, and a part of it is provided to Taihao Mountain every year - the books carried by the envoys. Among the classics, there may be paper made of raccoon and rabbit skin."
"..."
Being set up.
Bian Chenpei's face turned ugly again.
Taihao Mountain has concentrated all the resources in the world, and the students' food and clothing expenses are even more "lavish" than ordinary royal children, and they don't care about the daily necessities at hand.
If he said raccoon rabbit skins were contraband, how would he explain it if the academy found related items from them?
You can't offer wine in front of the academy or in front of foreign students.
You insist that the contraband in the Academy is contraband, but the contraband in Taihao Mountain does not count, right?
"If there are no problems, then I will start."
Li Ang smiled slightly, opened the cockpit's skin door, and sat on the seat.
Calling it a cabin is actually quite reluctant.
There is not much redundancy in the narrow space. The crankset, chain, etc. are all exposed. You need to be extra careful when pedaling to prevent scratches and injuries to yourself.
To outsiders, this aircraft seems particularly weird and crude, but in Li Ang's eyes, every part of this aircraft is the crystallization of human wisdom.
It has a very beautiful name in the memory of another world - Gossamer Albatross.
It was designed and manufactured by American aerospace engineer Mike Creedy, and uses human muscle power to drive gears, chains, and propellers to fly.
And on June 12, 1979, driven by Brian Allen, it took 2 hours and 49 minutes to fly 37 kilometers across the sea and flew across the entire English Channel.
All kinds of information flashed through Li Ang's mind, and he looked out through the cockpit skin.
Under the command of Su Feng, everyone around them dispersed and cleared a runway in the open forest.
Everyone's eyes were focused on this strange-looking aircraft and Li Ang in the cockpit.
"Can this fly?"
"It looks so bulky, completely different from the previous model aircraft."
"And it's made of wood, so it really won't fly apart and fall apart?"
The surrounding discussions reached my ears with the breeze,
Li Ang smiled slightly, looked back, put his hands on the handles, and slowly stepped on the pedal.
The high-precision transmission device manufactured by Tantai Leshan itself has no harsh metal friction sound. The pedal drives the crankset and drives the flywheel to rotate from slow to fast.
The chains flowed at high speed, driving the propeller blades behind the aircraft to rotate slowly.
The propeller blades generate wind, pushing the aircraft forward slowly and accelerating.
The pulley under the cockpit rotates across the lawn until it breaks away from the ground.
Amidst the disbelieving looks, the aircraft left the earth.
The huge horizontal wings are shrouded in the morning light, like the wings of a giant beast, spreading shadows.
"It actually, really, flew..."
Students from all over the world subconsciously opened their mouths.
Yu Feiyu's eyes narrowed slightly, and his profound spiritual consciousness that was incompatible with his age swept into the sky and enveloped the aircraft.
There is no telepathy, no talisman, not even the slightest fluctuation of spiritual energy.
This aircraft is indeed, as Li Ang said, a flight driven purely by human power.
"How...possible..."
Bian Chenpei looked livid and murmured to himself,
It is difficult for ordinary people to even lift heavy objects equal to their own weight.
And with such an aircraft, it can break away from the constraints of the earth?
"Nothing is impossible,"
Ou Zhiyuan looked at the aircraft and said with emotion: "Do you remember that lift formula that you abandoned like a worn-out shoe?
Lift is equal to the lift coefficient, times one-half, times the speed times itself, times the air density, times the wing area.
