Amid the uproar in the world, another week passed in the blink of an eye, and the East China Sea Fleet finally returned to its 18th branch.

After getting off the warship, Li Yan went directly to the west of the island, where the airship was built.

When he saw this thing in front of him, which was completely unrelated to the style of the pirate world, Li Yan was also a little excited.

Although it was just a test airship, Levine and the others did not build it very big, but it was still more than 78 meters long.

Of course, the 78-meter length refers to the rigid frame structure airbag above it, not the pod below.

However, this has also made it as big as a naval medium-sized warship.

"Levin, when will the test start?"

"You can do it at any time, General!"

"Ain, find ten people who are proficient in using Moon Steps to accompany you during the entire test session to prevent accidents!"

"Okay, I'll go right away!"

Although Li Yan was very confident in the technology provided by the system and Levin's ability, after all, it was the first time to test this kind of thing, so it was better to be careful.

At least...

Bringing a group of sailors who can walk on the moon, even if something happens, they can save all the scientific researchers involved in the test, right?

A few minutes later, Ain was back.

Following her back were ten elite marines from the branch, all of whom had learned the Moon Step and were relatively proficient in its use.

"Everyone is boarding the boat. Each person is responsible for protecting a researcher from the Science Department. If any accident occurs during the test, they will immediately use the moon step to protect the safety of the people in the Science Department. Do you understand?"

"Yes, General!"

Counting Levine, there were a total of ten scientific researchers participating in this first flight test, so Li Yan also mobilized ten sailors for one-on-one protection.

Soon, after all the people from the Science Department and the navy entered the pod, Li Yan also walked in with Ain and Nokigao.

The pod was not big, with a length of less than ten meters and a width of less than 3 meters, but it was enough to accommodate more than 20 of them.

To be honest, even though Li Yan came from that era, he only had a rough idea about airships and didn't know much about them.

After all, ordinary people usually don't have access to this kind of thing.

Therefore, Li Yan was very curious about everything in this airship.

"Levin, before it starts, can you give us a brief introduction?"

"Yes, General!"

The preparation work was all busy by his own men, and he did not need to participate. Levin also nodded.

"According to the technical information provided by the general, this type of airship should be classified as a rigid airship. Compared with soft airships, rigid airships use a frame structure in the airbag, allowing them to be built larger!"

"Theoretically, we can use this design to create an airship comparable to the size of a battleship!"

"Of course, the main volume of the airship is in the airbag. Even if it is made larger, the number of people it can carry at one time is still very limited. This is a flaw!"

"However, this defect is not unsolvable, and our Ministry of Science has prepared several solutions, pending further testing for confirmation."

"In addition, according to our design parameters, the theoretical ceiling of this test boat can reach 12,000 meters, and the theoretical speed can reach a maximum of 57 knots!"

Li Yan and the other three listened carefully.

And when Levine talked about the theoretical ceiling and speed, Li Yan's expression became weird.

With a ceiling limit of 12,000 meters, doesn’t it mean we can go directly to the sky island?

Speaking of which, there are a lot of good things on Sky Island...

It's not that Li Yan hasn't had the idea of ​​​​an empty island, but there are only a few people in the entire branch who can directly land on the empty island by moonwalk.

Therefore, even if we go up to kill Elniru now, it will not make much sense to capture the empty island, because ordinary sailors cannot go up at all.

We can't let them go up in those dangerous ways, right?

But with this airship, it's different. I can continuously transport troops and some things that are inconvenient to reveal to the air island, thereby minimizing the possibility of leaking my secrets.

The key is...

There is still Shantara on this empty island!

Look at the original work, Luffy and the others just packed up some small things and sold them for 300 million beli after returning to Qinghai.

Think again about that huge golden pillar carried by dozens of machines...

I'm afraid it's worth at least tens of billions, right?

Not to mention, there is the big clock and the golden ship built by Enel.

Therefore, as long as the empty island is captured, no matter what major projects you want to carry out in the East China Sea, you will no longer be short of money.

Once this idea appeared, it could no longer be suppressed.

After all, the gold in Shantora and a perfect location like Sky Island are very important to Li Yan...

The temptation is too great!

"Minister, all preparations for takeoff are completed!"

"general?"

While Li Yan was thinking about this, a researcher from the Ministry of Science came to Levin to report.

Levin looked at Li Yan.

After all, with Li Yan here, the order for the first flight would naturally come from him.

"Let's get started. You are a professional in this area. I, a layman, will not give you orders!"

"Yes, General!"

After nodding, Levin came to the operator's seat at the front of the pod.

"Bleak the air out of the passenger air bag!"

"Yes, the auxiliary airbag is being exhausted... After the exhaust is completed, the airship has obtained sufficient lift!"

"Unlock the rope!"

"It has been released. The airship has begun to rise. It is currently 0.7 meters per second and is accelerating slowly!"

The huge airship, without the restraints of fixed ropes, immediately left the ground and continued to rise slowly.

However, this speed of increase is not very fast. Even if it reaches the maximum speed later, according to Levine's theoretical data, it should only be seven or eight meters per second.

"It's really flying..."

Unlike Li Yan, Ai En was really shocked.

After all, people in this world are still very unfamiliar with flying.

This is just like everyone's shock after Li Yan's first airplane was built in his previous life.

Not only him, but all the sailors who participated in this test also had their eyes widened at this moment, looking at the scene outside the pod.

They really didn't expect that they could go to heaven without relying on moon steps...

Unlike the surprised expressions of these marines, the people in the Science Department were all very serious and busy.

"Pay attention to the attitude of the airship and don't be careless!"

"Yes, Minister!"

"Has the current acceleration been measured?"

"It has reached 2.7 meters per second and is still slowly improving!"

"Continue, wait until the altitude is one thousand meters, then inflate the auxiliary air bag immediately and stop rising!"

"clear!"

At the front of the pod, Levin was still giving instructions.

The first part of today's test is to climb to an altitude of 1,000 meters, and while maintaining this altitude, try to fly smoothly at more than 30 knots.

As for the ultimate altitude and ultimate flight speed, those are not things that should be tested on the first flight.

A few minutes later...

"Minister, the height is one thousand meters!"

"Stop rising, adjust the attitude of the airship and start the thrusters, and try to fly smoothly!"

"yes!"

When the airship stopped rising and started flying using the propulsion device, Li Yan also came to the front of the pod and asked a question out of nowhere.

"Levin, what is the propulsion device of the airship powered by?"

"General, this is the latest Coca-Cola power system developed by Carrera Company!"

"Is it a pure power system, not the hybrid power used on warships?"

"Yes, not steam power, but a pure cola power!"

Hearing this, Li Yan was also speechless.

Okay, should I say that he really deserves to be Frankie?
Chapter completed!
