Chapter 72 The Flywheel Catapult!
Thinking of this, a confident smile reappeared on Mo Tian's face.
He looked at Zhang Fan, his eyes once again filled with contempt.
Won!
……
at the same time.
On the city wall.
Ying Zheng could no longer remain calm.
He was restless and paced back and forth on the city wall.
But he forced himself to suppress his anxiety and pretended to be calm.
He stared intently at the few lonely pieces of wood in front of Zhang Fan, his heart filled with confusion.
What exactly is this thing?
He finally couldn't hold back any longer, turned his head to look at Marquis Wang Ben of Tongwu beside him, and asked in a deep voice:
"Minister Wang, in your opinion, what... is this thing?"
Wang Ben bowed, his expression equally solemn.
He hesitated for a moment before slowly answering:
"Your Majesty, judging from its shape, it bears some resemblance to the catapults used in the army."
"But...it's completely different!"
"A typical catapult requires a huge counterweight stone or a torsion rope that dozens of people work together to twist in order to launch a stone projectile."
"But this thing... has a simple structure, no counterweight, no winch, and I... cannot see through it!"
After listening to Wang Ben's analysis, Ying Zheng's heart sank even further.
Even Wang Ben couldn't see through it?
What on earth is this kid up to?!

Beneath the city wall.
Zhang Fan finally finished stretching his muscles and bones.
He took the heavy bronze ball handed to him by a maid.
He weighed it in his hand and casually placed it into the groove at the top.
That's right!
This is no ordinary catapult!
This is a team of top experts from Bureau 749.
Working through the night to design and overcome challenges, we finally achieved a perfect replica!
Flywheel catapult!
It does not require a heavy counterweight arm or a laborious manual winch!
Its true core is those few seemingly insignificant giant flywheels!
The kinetic energy applied by human power is transferred through levers and gear sets.
It is stored little by little in the high-speed rotating flywheel!
Once released, that terrifying angular momentum will instantly transform into unparalleled projectile force!
Just then!
The phone in Zhang Fan's arms vibrated slightly.
He glanced around.
Everyone's attention was focused on the crude catapult, and no one paid any attention to him.
A slight smile played on his lips as he brought the phone to his mouth and spoke quickly:
"Reporting, sir!"
"Target: earthen slope directly ahead, 117 meters away."
He looked up at the sky, then plucked a blade of grass from the ground to feel the wind direction.
"Wind speed at the scene: southeasterly, approximately 2.3 meters per second; humidity..."
Less than ten seconds.
The moment Zhang Fan finished announcing the data!
On the other end of the phone was the highest command center of Bureau 749.
That supercomputer, whose computing power rivals that of the Milky Way, has already completed all the ballistic simulations and parameter calculations!
Zhu Feng's calm and powerful voice immediately came through the earphone!
"receive!"
"Flywheel pre-acceleration, 12 laps!"
"Adjust the projectile arm angle upwards by 3.7 degrees!"
"Base azimuth, 1.2 degrees to the left!"
"Repeat! 12 revolutions of the flywheel! Angle 3.7! Orientation 1.2!"
A glint of light flashed in Zhang Fan's eyes!
Without making a sound, he placed the seemingly simple wooden frame.
I made minor adjustments based on the instructions transmitted through the headphones.
The movement was as fast as lightning!
To onlookers, he simply fiddled with it casually a couple of times.
Nobody knew about this rudimentary war machine.
At this moment.
It's all set to launch!
After doing all this.
Zhang Fan raised his head and looked at Mo Feng and Mo Tian, who were sitting opposite him with smug expressions.
He smiled.
"Are you ready?"
"I'm going to begin."
Upon hearing this...
The Mohist disciples all wore undisguised sarcasm on their faces.
"Let's begin! Let's begin! We can't wait to see you make a fool of yourself!"
"Hurry up and let your broken piece of wood do its thing! Don't keep us waiting!"
"Ha ha ha ha!"
Faced with the overwhelming ridicule.
Zhang Fan didn't care at all.
His face still held that calm and composed expression.
He reached out and groped the smooth bronze sphere for a moment.
Then, finally, they found something.
His finger gently hooked and pulled at an inconspicuous protrusion!
"laugh--"
He pulled a thin wire out from inside the bronze sphere!
A wisp of white smoke rose from the tip of the lead wire!
Having done all this, Zhang Fan no longer hesitated!
He gripped the hand crank on the side of the catapult with both hands and began to spin it violently!
"Crunch... crunch... crunch..."
The heavy flywheel, under his power, began to slowly accelerate!
One lap!
Five laps!
Ten laps!
As the flywheel spins faster and faster, the ear-piercing friction sound becomes increasingly sharp!
An invisible current of air spread outwards from the catapult as its center!
"What is he doing?!"
"This thing... it's hand-cranked?!"
"That's hilarious! How much strength could he possibly have all by himself?"
"Could you throw that bronze ball ten paces?"
The people pointed and whispered, their faces filled with even more mockery!
however!
Just as the flywheel was about to reach its speed limit, the entire wooden structure began to groan!
Zhang Fan's eyes flashed with a sharp light!
He suddenly raised his foot and aimed it at an inconspicuous latch at the bottom of the catapult.
He kicked it down hard!
"Snap!!!"
A crisp, almost deadly mechanical sound rang out!
That terrifying kinetic energy compressed to its extreme.
In this instant, let go completely!
"Buzz—!!!"
The launching arm swung upwards with a speed too fast for the naked eye to perceive!
The heavy bronze ball was thrown out with tremendous force to everyone's horrified gaze!
call out! ! !
It tore through the air, whistling through the sky, and headed straight for the small hill in the distance!
quiet!
The entire venue fell into a deathly silence!
Everyone's mouths gaped open involuntarily, their minds went completely blank!
fast!
too fast!
This speed has completely exceeded the limits of their understanding!
Sumida suddenly sprang up from his seat!
His cloudy old eyes were fixed on the bronze ball.
His mouth was agape enough to fit an egg, and his face was filled with utter horror and disbelief!
"This...how is this possible?!"
He gasped in shock, his voice trembling!
"This speed...this speed far surpasses even the most sophisticated counterweight catapults!"
"How...how did he do that?!"
"No counterweight! No torque! Where...where does that force come from?!"
He couldn't understand it!
He just couldn't understand it!
Angular momentum!
That terrifying angular momentum was not wasted in the slightest.
It was perfectly converted into projectile kinetic energy!
This...this is such an ingenious design!
What a terrifyingly ingenious idea!
At this moment, for the first time, a crack appeared in the rock-solid confidence in Sumida's heart!
Everyone's eyes were instinctively drawn to the trajectory of the bronze ball!
Under the breathless gaze of everyone!
The bronze ball traced a perfect parabola.
then……
"Thump!"
A dull thud was heard.
It crashed onto the ground, a dozen steps or so away from the small mound...
It bounced twice and rolled a few times.
Then, it just lay there quietly.
There was no further movement.
