Chapter 919

Soon, after half an hour, they finally stopped what they were doing.

"Well, don't you witness this great moment with me?" , Yang Feng was so busy that he was excited to invite Zhao Fengnian.

Zhao Fengnian hesitated when he heard Yang Feng's words, and then said with a smile: "ha ha, really? It's a great honor! "

Zhao Fengnian hesitated, of course, because he was afraid of his own safety problems after the spacecraft fell.

But think of Yang Feng and himself together, their own security should not be a problem.

Then they boarded the spaceship, and Wang Fenglin and others below opened the ropes to fix the spaceship.

"Well, here we go Yang Feng rubbed his hands excitedly. One hand moved the switch at one end of the boiler.

"Hula Lala..." "Gudu Dudu..." "Click, click, click..."

With the switch on, the boiler made a sound of boiling hot water. With this sound, a sound of gear rotation sounded slowly and quickly on Zhao Fengnian's head.

Zhao Fengnian looked up and saw that the huge propeller above his head was turning a little bit.

Zhao Feng still can't see the success of the first few years. However, it's not enough to see the first step up.

As Zhao Fengnian expected, the propeller was spinning faster and faster, bringing gusts of wind.

However, two minutes later, the speed of the propeller did not increase any more. It seems that it has reached the limit of fire power.

Can't help but, Zhao Fengnian looked at Yang Feng who was still satisfied.

Now Zhao Fengnian wants to have a look at what medicine is sold in Yang Feng's gourd.

"Hehe, it's about to start! Watch it When Yang Feng saw Zhao Fengnian and looked at him, he said with a smile that Zhao Fengnian should not worry.

Then I saw Yang Feng's right hand sticking to a piece of iron on the boiler.

It's black and shiny. Obviously, it's made of meteorite!

"Ah! So it is Seeing this, Zhao Fengnian suddenly realized!

Zhao Fengnian has never had a good way to smelt materials above refined iron. Before, he could only use the fine array of Tianlei gold.

But after Yang Feng came to yongfengling, he brought a new way of smelting, which was to transport Reiki to special furnaces.

In the last generation, adding oxygen to the flame could raise the temperature of the flame, which Zhao knew.

But Zhao Fengnian didn't know much about Reiki. He didn't expect that Reiki had the same effect as oxygen, even more domineering and rapid than oxygen.

Now yongfengling meteorite iron forging, is generally used in this way, so Zhao Fengnian can see at a glance.

If the temperature in the boiler rises sharply, the pressure will continue to increase. After the increase, there are two results: one is to provide stronger power to the propeller; the other is to explode directly!

However, Zhao Fengnian is not worried about the second result, because he believes that the boiler system Yang Feng must also have undergone special treatment.

It seems that today we really have to witness the birth of the first manned aircraft in the world!

"Hoo Hoo Hoo Hoo..." At this moment, the speed of the propeller increases again, making a rapid and continuous wind sound.

"Ah! Look! It's flying! It's really flying

Then Zhao Fengnian felt a shake at his feet and heard the excited voice of Wang Fenglin and others below.

Gradually, the scope of the spacecraft shaking reduced, steady speed toward the air.
