"Everyone, thank you for your hard work!"

When Liang Ming, the second-class craftsman, heard these words, he was frightened and felt that all the grievances and sadness were worth it.

Honestly.

Both he and his master were marginalized figures in the Tiangong Palace, and they were subjected to all kinds of exclusion and suppression, both covertly and covertly.

Although the House of Internal Affairs informed Tiangong Hall and asked Tiangong Hall to try its best to meet all the requirements of Special Envoy Cheng, he and his master still encountered a lot of hidden difficulties.

For example, when I go to the warehouse to collect materials, I often get inferior products.

Another example is that applying for funding resources is always delayed.

There are even more unpleasant rumors.

Words such as "I don't do all the good work and just build these useless toys" are relatively polite words.

Rhetoric such as "A master craftsman, in order to please the special envoy, does not do his job all day long, causing other craftsmen to work overtime every day, it is really shameless." This kind of words are everywhere.

In a word, these days are really difficult.

Now Liang Ming hopes from the bottom of his heart that the internal combustion engine designed by the special envoy can come out as soon as possible, and bombers can soar in the sky as soon as possible.

At this time.

Cheng Han walked around the testing machine and nodded with satisfaction: "Very good!"

Liang Ming smiled cautiously.

Although Cheng Han had specifically stated before, he just wanted to do a few simple experiments and didn't need to spend too much energy on making a prototype.

But this testing machine is extremely finely made, and every detail is handled meticulously.

Just give me an example.

There is a layer of metal skin on the surface of the wing, which looks smooth and smooth without any dents, showing extremely superb craftsmanship.

Cheng Han walked to the nose of the test machine and turned the propeller hard.

"Huh~"

The whistling sound started.

The propeller begins to spin rapidly.

The appearance of this test aircraft is highly consistent with the metal monoplane fighter in the simulation.

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

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

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

A group of apprentices had no idea they were witnessing history.

They just watched this scene curiously, secretly guessing how to play this big toy.

That’s right!

It’s just a toy!

Within Tiangong Hall, almost everyone believed that this was a big toy that the special envoy forced Tiangong Hall to create in order to satisfy his own strange habits.

But for the talented Xuanshi who caused a sensation in the entire Xuan Palace and was especially favored by the palace owner, Tiangong Palace could only let it go and at most complain a few words in private.

"Snapped!"

Cheng Han snapped his fingers.

"Wow~"

The spirit oak demons immediately started shaking and responded positively.

A large canopy of branches quickly extended over and instantly formed a soft ladder, erected between the ground and the cockpit.

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

This situation cannot help but make the apprentices envious.

Cheng Han held the rudder, stepped on the pedals with both feet, and shouted softly: "Get up!"

More spirit oak demons suddenly started to move.

Thousands of branches swam over and formed a giant net underneath the body, lifting the entire test machine half a meter high.

The apprentices became even more curious.

What does the special envoy want to do?

next moment.

"Whoosh!"

Only a roar was heard.

The spirit oak demon suddenly threw up the giant net of branches and threw the test machine high into the sky.

It was originally as planned.

Fighter planes use agile mysterious formations to take off and land, converting source energy into kinetic energy and reaching takeoff speed instantly, without the pilot feeling the acceleration.

But the test conditions are limited.

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

"Oh my God!"

"Oh my god!"

A group of apprentices exclaimed.

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

The craftsman knew very well that this was a test machine specially designed by Special Envoy Cheng based on the inspiration of the "paper airplane".

Liang Ming had heard about this from his master at first, and had also thought about designing a so-called bomber in this way.

Later, the master and apprentice saw the design drawings sent by Cheng Xuanshi, especially the ingenious propeller drive method, and were greatly impressed by it.

What a genius!

Even the craftsmanship skills are so amazing!

at this time.

In the sky.

Cheng Han stepped on the pedal so hard that his legs almost left an afterimage.

No internal combustion engine?

It doesn't matter!

Every physically strong warrior is a humanoid engine.

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

Just push it and it’s done!

"Woo~"

The propeller turned rapidly.

The test machine was pushed by the reaction force and flew out quite smoothly.

And the altitude is flying higher and higher.

below.

"Wow~"

The spirit oak demons waved their branches together, seeming to express their joy.

The apprentices all raised their necks and opened their mouths wide.

Oh My God!

An iron shell can actually fly?!

Special Envoy Cheng is really good at riding horses!

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

Flying!

Judging from the flight attitude, the test machine showed strong stability, and such a complex design was actually successful in the first try!

It’s really amazing!

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

In the sky.

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