[Ding dong--Congratulations to the host on the birth of a daughter. The system has specially sent a gift package. Please check the host!]

In Yuxuan Pavilion, Ying Yu, who was teasing Little Bubbles, was slightly stunned, and then a hint of joy flashed on his face.

I didn’t expect the system to be so smart and even know how to send gifts, which is great!

"The system opens the gift package!"

[Ding Dong--Congratulations to the host for gaining reputation: 100 million!]

[Ding Dong--Congratulations to the host for getting a copy of "Iron-eating Beast Taming Manual"!]

"sure!"

Originally, Ying Yu thought that the system was just perfunctory, and even if it gave him a gift package, it would not give out good things.

It seems that I have misunderstood. What Ying Yu lacks most now is reputation. This 100 million reputation came just in time.

As for the "Iron-eating Beast Taming Manual", isn't that the national treasure giant panda?

Although it is not as practical as the police dog training tips given last time, it is still a good reward.

It seems that I have to catch a few Yuangunguo back when I have time. If I can successfully tame them and make them humane, they will be very good as pets for the little guys.

The cute and powerful cat is a world-famous star even in later generations, and he has many loyal fans.

I think it will also be liked by my own little Paopao and another little one who is about to be born.

Ying Yu opened the system panel with satisfaction.

【Host: Ying Yu!】

[Identity: Prince of Da Qin! 】

[Combat Power: Human Limit (As long as you are a human, I can’t beat you!)]

[Reputation value: 220 million!]

[Items: Red tripod with dragon pattern, Fangtian painted halberd, red rabbit horse, Xuanwu armor, sun-shooting bow, Zhonghua brand cigarettes, lighter, mineral water, etc.]

[Lottery chance: 2 times!]

[Followers: Shen Wansan, Zhao Yun, Yang Zaixing, Jin Yiwei, Yan Yun Shibaqi, etc.]

[Reputation Mall: Opened!]

[Evolution function: turned on!]

"Yes, the reputation value has exceeded 200 million, and another blueprint can be evolved."

Ying Yu thought for a while and finally decided to use 200 million reputation points to evolve the hot air balloon blueprint.

The first test flight of a hot air balloon brought a sensation to the entire Daqin, and even the entire world, but I still vividly remember it.

However, the hot air balloon is only the initial aircraft after all, and in Ying Yu's opinion, it is still quite crude.

First of all, it can only rise and fall independently, and move laterally, completely depending on the wind direction. It is fine for short and medium-distance flights. For long-distance flights, there are too many uncertain factors because Daqin's current climate measurements are still relatively primitive.

Moreover, due to the limitation of lift, it cannot be made too large, so the structure of the passenger compartment is relatively simple.

Although hot air balloons can theoretically lift up to five thousand meters or even ten thousand meters, the cold at high altitude is not so pleasant.

If the hot air balloon can be upgraded to an airship, the above problems can be greatly improved.

[Ding Dong--Congratulations to Su for successfully upgrading the "Hot Air Balloon Manufacturing Blueprint" to the "Improved Helium Large Flying Blueprint", please check it out!]

"Sure enough, our Xiner is our father's lucky star!"

Ying Yu lovingly kissed her little daughter on the face.

There are actually many types of airships. The most primitive airships use hydrogen. Although it is easy to obtain, it has a relatively high risk factor due to its flammability.

Because of uncertain factors such as lightning, hydrogen airships can be said to be relatively limited.

The helium airship is an upgraded version of the hydrogen airship.

As an inert gas, helium has an extremely high safety factor. Combined with the previously obtained flame-retardant coating, it can make the airship safer.

Moreover, the system also comes with a helium production method. In addition to being used to inflate airship airbags, helium is also very useful for other scientific research projects.

The only disadvantage is that the cost of helium is much higher than that of hydrogen.

But for Ying Yu, anything that can be solved with money is not a problem.

Ying Yu continued to study the "Improved Helium Large Airship Blueprint".

This is a hard-shell airship with a complete skeleton. It is a large airship that can maintain its basic shape even if it is not inflated. The specific parameters are as follows:

Total length: 120 meters.

Number of air bags: 200.

Total volume of air bag: 108025 cubic meters.

Airship height: 35 meters.

Maximum diameter: 28 meters.

Maximum load capacity: 12 tons.

The length of the crew cabin is 15 meters.

The width of the passenger compartment is 8 meters.

Cruising speed is 120 kilometers per hour.

Maximum speed 150 kilometers per hour.

The maximum flight altitude is 6500 meters.

The maximum flight distance is 2,300 kilometers.

"The product produced by the system is indeed a high-quality product. The 200 million reputation is well spent."

Ying Yu is very satisfied with all the data of the helium airship.

If such an airship could be built in Great Qin, it would definitely be as big as a Big Mac.

With a load capacity of 12 tons and a passenger cabin area of ​​nearly 100 square meters, it is enough to accommodate dozens of people at the same time.

The flight distance of 2,300 kilometers is enough to fly from Xianyang City to any county in mainland Daqin, replenish fuel, and reach Tianzhu and Persian counties.

As a result, Xianyang City's control over the newly incorporated land will directly increase countless times.

Even if Ying Yu and Ying Zheng cannot go there in person, the airship only needs to patrol the skies over each county every month to bring enough shock to the local area.

Although the flying speed of more than 100 kilometers is far from that of an airplane, it is several times faster than a hot air balloon.

Moreover, the flight of the airship can be controlled independently, which is incomparable to the hot air balloon.

Although airships are slow, they can stay in the air much longer than airplanes. Even in later generations, airships have unique applications and have never been completely eliminated.

For today's Great Qin, it is even more like an artifact that governs the country.

After truly mastering airship technology, scientific research institutes and engineering academies can try to build some miniaturized manned airships so that Daqin's special forces can truly gain wings and travel to any place in the world at any time.

By then, the world's first air force will also be born in Daqin.

Once it appears on the battlefield, not to mention how powerful it is, its intimidation alone is enough to demoralize the enemy and cause chaos.

Coupled with the investigation and assassination of special forces, as well as Da Qin's already far superior military strength, it was enough for Da Qin's soldiers to sweep across the world.

As soon as the Suez Canal is opened, the Great Qin Navy can enter the Mediterranean. Rome and Carthage will definitely not be able to stop the Great Qin's pace.

Thinking of this, Ying Yu couldn't help but think.

Nowadays, the Qin Navy does not have many combat missions for the time being, and it will take time to open the Suez Canal.

Is it possible to consider setting up some small teams to start exploring the New World?

Whether it is the American continent in the north or the Australian continent in the south, they are both rich in resources, extremely fertile, and extremely suitable for reproduction and development.
