Let's start by analyzing the sun

"Everyone, you've worked hard!"

Hearing these words, Liang Ming, a Grade B Artisan, felt that all the grievances and hardships were worth it, amidst his trepidation.

Honestly speaking.

Both he and his master were marginal figures in the Heavenly Crafts Hall, subjected to various forms of open and covert ostracism and suppression.

Although the Internal Affairs Hall had informed the Heavenly Crafts Hall to do its best to meet all the requirements of Special Envoy Cheng, he and his master still suffered a lot of subtle difficulties.

For example, when going to the warehouse to collect materials, they often received inferior goods.

Also, the funding and resources they applied for were always delayed.

There were even more unpleasant rumors.

Words like "Instead of doing proper work, they insist on making these useless toys" were considered relatively polite.

Remarks such as "A grand artisan and an artisan, they don't do their jobs properly all day to please the Special Envoy, causing other artisans to work overtime every day, they're so shameless" were even more common.

In a word, life was really difficult.

Now, Liang Ming sincerely hoped that the internal combustion engine designed by the Special Envoy could be launched as soon as possible, and that the bomber could soar in the sky as soon as possible.

At this moment.

Cheng Han circled the experimental machine, nodding with satisfaction: "Very good!"

Liang Ming smiled with restraint.

Although Cheng Han had specifically instructed him earlier that he only wanted to do a few simple experiments and did not need to spend too much effort to manufacture a prototype.

But this experimental machine was made with exceptional care, with every detail handled meticulously.

Just to give an example.

The metal skin on the surface of the wing looked flat and smooth, without any dents, demonstrating extremely superb skills.

Cheng Han walked to the nose of the experimental machine and vigorously turned the propeller.

"Whoosh~"

A whistling sound rang out.

The propeller began to rotate rapidly.

The appearance of this experimental machine was highly consistent with the simulated metal monoplane fighter.

In order to adapt to vertical take-off and landing, the landing gear had been greatly simplified. Since the internal combustion engine had not yet been developed, a power device similar to a bicycle was installed.

Cheng Han smiled and said: "Then let's conduct the first verification."

Only he understood that this was a historic experiment, and also an experiment that foreshadowed the rise of ordinary people onto the stage of history.

A group of apprentices did not know that they were witnessing history.

They just watched this scene curiously, secretly guessing the gameplay of this big toy.

That's right!

It was just a toy!

Inside the Heavenly Crafts Hall, almost everyone believed that this was a big toy that the Special Envoy had forced the Heavenly Crafts Hall to make in order to satisfy his strange hobby.

But for the genius Xuan Shi who had caused a sensation throughout the Xuan Palace and was particularly favored by the Palace Master, the Heavenly Crafts Hall could only listen and let him do as he pleased, at most complaining a few words in private.

"Snap!"

Cheng Han snapped his fingers.

"Whirr~"

The Spirit Oak Demons immediately shook and responded actively.

A large bunch of branches rapidly extended, instantly forming a soft ladder, erected between the ground and the cockpit.

Cheng Han leisurely stepped on the soft ladder, quickly climbed into the cockpit, and sat on the driver's seat.

This scene could not help but make the apprentices envious.

Cheng Han gripped the rudder, stepped on the pedals, and shouted softly: "Rise!"

More Spirit Oak Demons moved at once.

Thousands of branches swam over, weaving a giant net under the body, and lifted the entire experimental machine half a meter high.

The apprentices were even more curious.

What did the Special Envoy want to do?

The next moment.

"Whoosh!"

Only a whistling sound was heard.

The Spirit Oak Demons suddenly and forcefully swung the branch giant net, throwing the experimental machine high into the sky.

Originally, according to the design.

The fighter's take-off and landing used the Spiritual Kinetic Xuan Formation, converting source energy into kinetic energy, which could instantly reach take-off speed, and the pilot would not even feel the acceleration.

But due to the limitations of the experimental conditions.

For the time being, only a simplified version of vertical take-off and landing can be used.

"Heavens!"

"Oh my!"

A group of apprentices exclaimed.

Liang Ming clenched his fists, his face full of anticipation.

This artisan knew very well that this was an experimental machine specially designed by Special Envoy Cheng based on the inspiration of "paper airplanes".

Liang Ming had heard about this from his master and had also pondered about designing the so-called bomber in this way.

Later, the master and apprentice saw the design drawings sent by Xuan Shi Cheng, especially the cleverly structured propeller drive method, and admired it greatly.

As expected of a genius!

Even the skills of a craftsman are so amazing!

At this time.

In the sky.

Cheng Han vigorously stepped on the pedals, his legs almost creating an afterimage.

No internal combustion engine?

It doesn't matter!

Every physically strong warrior is a humanoid engine.

With just two legs, he can easily output a hundred horsepower.

Just use force!

"Ooh~"

The propeller spun rapidly.

Driven by the reaction force, the experimental machine flew out quite smoothly.

And the altitude flew higher and higher.

Below.

"Whirr~"

The Spirit Oak Demons waved their branches together, seemingly expressing their joy.

The apprentices all raised their necks, each with their mouths wide open.

My God!

An iron shell can actually fly?!

Special Envoy Cheng is really too good at playing!

Liang Ming was so excited that he couldn't control himself.

It flew!

Judging from the flight attitude, the experimental machine showed strong stability, and such a complex design was actually successful in one go!

It's really amazing!

Liang Ming couldn't help but turn his head to look in the direction of the Heavenly Crafts Hall, and murmured in his heart: "Master is right, the bomber is not a fantasy, but a completely achievable concept!"

At this time.

In the sky.

Cheng Han looked down at the scenery on the ground, and slightly grinned: "This can be regarded as the first step in changing the world."

He roughly sensed it and murmured: "The speed is close to two hundred kilometers per hour, barely passable."

Converted, it's about fifty meters per second.

In comparison, it's only equivalent to one-third of a Xuan Shi's wind-riding flight.

Cheng Han silently said: "Deduction!"

Stars appeared in the sky.

A halo appeared with it.

A large amount of information flashed across the screen.

This was precisely the huge amount of data collected by the All-Knowing Eye from this experiment.

After more than ten seconds.

Cheng Han said again silently: "Optimization!"

In the very center of the halo, a new stream of information immediately surged.

This included knowledge of aerodynamics, as well as various optimization schemes for aerodynamic shapes.

This was the core purpose of this experiment.

Since there was no wind tunnel to blow, he would just fly directly.

This was also something that couldn't be helped.

Because this world did not have this set of knowledge system.

The All-Knowing Eye could not search for relevant information, and must accumulate data through actual experiments.

Cheng Han manually adjusted the rudder, and controlled the experimental machine to fly towards Heavenly Ring A.

The Xuan Palace stipulates that Xuan Shi below the Xuan Shi level are prohibited from wind-riding flight in Heavenly Ring A.

But it did not prohibit aircraft from flying.

Cheng Han smiled: "Playing a side ball, no one can say anything."

If other Xuan Shi played like this, they might be reprimanded.

But geniuses have privileges, what are they afraid of?

Cheng Han muttered in his mouth: "Today, I will first leave an initial impression on the Xuan Shi of the Xuan Palace, although it will not be a good impression.

He chuckled: "In the future, when the real fighter is launched, it will be much faster than Xuan Shi's wind-riding, and I will surprise you all."

Heavenly Ring A.

Heavenly Enlightenment Hall.

Since the sudden emergence of Special Envoy Cheng, the Xuan Shi of this hall have paid special attention to him.

This is very normal.

This genius Xuan Shi had not been in the Xuan Palace for long before he brought down a managing Xuan Shi of this hall and sent him to the alien battlefield.

This matter left a very deep impression on everyone, and it was difficult for everyone not to pay attention.

At this moment.

A small black dot that flew up from the Spirit Oak Demon Forest was quickly noticed by the Xuan Shi.

When the small black dot flew towards here, the Xuan Shi whispered.

"I've inquired, that's the toy that Special Envoy Cheng asked the Heavenly Crafts Hall to make."

"It can actually fly in the sky, this thing is quite interesting!"

"What's interesting? Xuan Shi can catch up effortlessly by riding the wind, and destroy it with a single blow, it's useless at all!"

Everyone stood behind the huge glass window, watching the experimental machine fly into the edge of Heavenly Ring A, circled in the sky, and flew back to the Spirit Oak Demon Forest.

The Xuan Shi withdrew their gazes and discussed in a low voice again.

"During this period of time, I remember that Special Envoy Cheng has only been to the Inheritance Hall twice, and the rest of the time he stays in the Spirit Oak Demon Forest every day.

"Is this how you comprehend the Xuan Seal?"

"People are geniuses who attract spiritual tides, and they have the qualifications to be capricious!"

"Yes! Even the Palace Master wouldn't say anything!"

*

Jinshan Palace.

Xuan Palace Master Yun Changtian also learned of the news of the experimental machine.

As the Palace Master, he knew more information than the Xuan Shi.

Palace Master Yun muttered with some doubt: "Bomber? It flies so slowly, it has almost no practical value, is this really feasible?"

Xuan Du hesitated for a moment, and immediately made a decision in his heart: "Looking at the face of the genius, let's make a small bet."

He showed a sly smile: "Even if there is no result, it's just a waste of a little material, if it really succeeds, this is a merit!"

*

That afternoon.

Liang Ming learned a piece of news from his master.

"The Palace Master has just issued an edict, deciding to establish a research institution, managed by Special Envoy Cheng, and we have been transferred to this institution."

This Grade B Artisan was stunned for a moment, not quite understanding the significance of this.

The Grand Artisan said more specifically: "The funding and materials of this institution go directly through the channels of the Internal Affairs Hall, and there is no need to deal with the Heavenly Crafts Hall."

Liang Ming finally understood, and his face was deformed with laughter: "In that case, we don't have to be restrained by the Heavenly Crafts Hall?"

The Grand Artisan nodded heavily, his tone sweeping away the depression of the past: "Let's follow Special Envoy Cheng to do something big, and in the future, this research structure can swallow the Heavenly Crafts Hall."

As long as the bomber is built and its practical value is truly demonstrated, the Xuan Palace will definitely give people and resources, and merging the Heavenly Crafts Hall is not a big deal at all.

Liang Ming burst out with a strong fighting spirit, and said fiercely: "In the future, I, your father, will definitely sweep those old dogs out of the house."

The "old dogs" in this guy's mouth were a group of grand artisans in the Heavenly Crafts Hall who ostracized his master and apprentice.
