Chapter 857 Complete the air fortress? (3 for support)

After the "morning exercise", Liu Feng was eating breakfast with Mina and others in the restaurant.

The girls didn't ask much about where Liu Feng went all day yesterday, but just froliced ​​and grabbed food as usual. After eating, they went to do their own business.

Instead, An Li came down today and followed Liu Feng and Mina to the study.

"crunch..."

"It's been hard work for you these past few days, and it's rare for you to be free. Why don't you go around the city?" Liu Feng opened the door, sat down in his seat, and looked at En Li.

"Don't go, it's still comfortable for the young master here. It's enough to run around outside these days." En Li flicked her fox's tail and chewed the small dried fish she snatched from Mina's hand.

Mina stared at the small dried fish that she just took out and hid it again.

"You can rest for a few days, it's not a big deal, just tell them to go down and let them do it." Liu Feng opened the drawer and took out a box of lollipops from the side of the earth yesterday.

There are a total of twelve sticks in a box, each of which is transparent and has a starry sky inside. It is a starry sky lollipop unique to the earth.

"Wow, take a good look, thank you young master." An Li took the lollipop, her brown eyes no longer had eyes, and she turned to the west.

Mina glanced at the side, curled her lips, and said nothing, because after her 'morning exercise' this morning, she also got a package of small dried fish, cumin-flavored, which she had already hidden.

"Bang bang bang. Brought here. There was a sudden knock on the door.

"Sir, I'm Yuffie." The voice of the dwarf Yuffie came from outside the door.

"Yuffie, is that something progressing?" Liu Feng guessed, and then said, "Come in. There is no room for other things..."

"Tap tap..."

After receiving Liu Feng's response, Yuffie opened the door and walked in.

"Sir." With a look of excitement on Yuffie's face, she saluted Liu Feng..." The room has progressed, is it already done?" Liu Feng looked at Yuffie with a smile, this was her The second time I took the initiative to find myself.

The first time I came here, I gave myself a big surprise and discovered a new alloy, so this is the second time.”

"What about crunch?

"Sir, the outer shell of the air fortress is ready, please give me some advice." Yuffie said excitedly. There were traces of red blood in those eyes. It seemed that she was working overtime during this time. .

"It seems that Feng Feng was surprised. After seeing the red blood in Yuffie's eyes and the exhaustion on his face, he didn't know why it was so fast.

"It's just the shell, the gondola and steam engine have not been installed, and the helium gas has not been solved yet. Will there be another surprise? I lowered my head slightly.

"You've done a good job. As for the helium problem, leave it to me to solve it." Liu Feng praised Yuffie. The completion of the shell was much shorter than he expected.

​​

"So fast?" Liu Chong's gas can actually be filled with hydrogen, but hydrogen is flammable and explosive. Helium will not. Although helium is more expensive than hydrogen, Liu Feng finally chose helium as the filling gas for safety.

. "Yuffie seemed a little embarrassed and had to wait for Liu Feng to return to Earth to order the machine before it could be produced.

"Let's go, let's go and have a look." Liu Feng stood up, a little curious about the airship shell that Yuffie made.

And helium, in fact, is the filling of the airship, and they are also curious and a little excited.

They knew what Yuffie was doing, it was the Sky Fortress, and they could take them across the Forbidden Mountains and back to the Kingdom of Brutus, whether it was hydrogen or helium, to the carriage of the scientific research department, along the way. Yuffie is a little nervous. This is the first time she has completed a research independently, and it is the Sky Fortress she most hopes to research. She does not want to make mistakes.

Liu Feng: "Okay." Mina and Anli nodded, they only knew the result after seeing the real thing.

"Ta Ta Ta..."

Twenty minutes later, the carriage stopped in front of the gate of the scientific research department.

"Sir, here we are. Side.

The group walked out of the castle, got off the carriage with everyone, and walked towards the Sky Fortress Research Institute in the Scientific Research Department.

As soon as he entered the door, Liu Feng's sight was filled with an object. In front of him, a large figure looked at Yuffie's hand grasping the corner of his clothes, not to mention that the body was made of new alloys.

And this behemoth is the outer shell of the sky fortress, which is the core part of the airship, at a rough glance, it must be forty meters in length," Zink's voice came from outside the carriage.

Liu Fengxiang, there is a small propeller at the end.

Mina and Enri are also eating 'rugby' and are placed in front of many wooden frames supported by many wooden frames. They don't understand how this thing can fly. Is it like a hot air balloon, it needs to be ignited and fueled?

"Maybe it's a bit big." Yuffie looked at Liu Feng and the others with a diameter of eight meters and four tail wings to control Fang Xiao. "Liu Feng doesn't think it's big, it doesn't matter if the first trial is small.

"Master, can this really fly?" En Li asked suspiciously.

"Can you, startled, stare at this 'big football' and turn around. After all, this is the first time to build an airship, and I have no experience in the past, only a lot of theoretical knowledge.

"Oh." An Li nodded and didn't ask any more questions. Since the young master said his expression, she was a little embarrassed.

"It's not big, it's a little...

"Sir, this is the air release valve, and here is the place where the hanging basket is installed. You will know about the steam engine in about two months." Liu Feng had no idea in his heart. Started talking nonstop.

The entire airship, in addition to the shell, the most important thing is the deflation valve and the propeller, you will know in a month or two, then wait another two months.

It is an essential thing for airships.

"The remaining part can be completed within a month and a half, but the adult's helium gas is missing." Yuffie's pink eyes are filled with the installation here, which drives the propeller at the tail to rotate..." Yuffie gas should be able to solve it." Liu Feng figured out that he would go back to Earth to find someone to buy the equipment, and then disassemble it and ship it in batches. It should be almost two months.

One is to prevent the expansion of the filling gas from breaking the outer shell, and the other is to control the airship to move down. Don't worry about the rest. "Liu Feng pretended to be serious.

"Yes, my lord." Yuffie nodded quickly. She really didn't have a good rest during this time, and she was also bright. This was what she wanted to accomplish in her dreams.

"In two months, the helium room will not be good." Liu Feng couldn't help suggesting that Catherine and Lucy were staying in the castle during this time.

"Okay, my lord." Yuffie "That's great." Yuffie got excited.

"Okay, you should take a good rest and respond.
