Song Dynasty's Ignorant Prince

However, in Zhao Ji's opinion, this is not easy. These are fanatical religious people. As long as they have a unified command, they can bring a lot of trouble to the Song Dynasty.

It seems that it is only necessary to pay attention to both kindness and prestige. Those who are obedient are hello to me, hello to everyone, and those who dare to show their teeth must be resolutely attacked, such as those in Sanjar!

Those slaves all stared blankly at the busy people of the Song Dynasty. They didn't know what the black liquid could do, but they despised it in their hearts. They already knew that kind of thing, it would burn, but it only smoked a lot. It seems that the people of the Song Dynasty are really ignorant, and a faint sense of superiority has arisen!

At this time, a piece of good news came, the airship has made great progress, and an airship has been produced.

When Zhao Ji heard this, he was immediately happy, and he had been out for a long time, for nearly half a year. Although there are dozens of beauties here, he still misses Ling Bingyu and the others. They are the real wives in his heart, and they are just tools to vent his physical desires.

I also flew back several times during this period, but this time Zhao Ji plans to go back for a while. There is basically nothing to do here. Several surrounding countries are deploying troops to attack their holy city. Zhao Ji took the initiative to give up the road for hundreds of miles and let them fight each other.

The golden eagle was summoned, and Zhao Ji returned by the wind.

After going back, I went to the university first. Zhao Ji saw the finished airship. It was very ugly! It seems to be a feature of this era, and everything is not very beautiful. Not big, only ten meters long.

"Your Majesty, the helium gas rushed in here, and natural gas is used as fuel, just waiting for your Majesty to ignite it!" Zhang Shuye said.

Now Zhang Shuye has been transferred to Yanjing University as the vice president and concurrently the mayor of Yanjing City.

Zhao Ji laughed, "That's good, then I'll start this, I hope our airship can be successful!"

In fact, Zhao Ji just pressed it twice, there is an automatic ignition device.

With a bang, the flames started to burn, Zhao Ji retreated, special personnel began to debug, and hot air began to fill the gas tank.

There is a hanging basket under the airship, because the airship is relatively small, so it can only accommodate two people.

The two students were so excited that the first airship test flight would go down in history!

"It's not easy, it's been more than three years since the preparation started, and it's finally made!" Zhao Ji sighed.

Zhang Shuye also nodded. He also understood the production process of this airship. There are many things in it that need to be experimented. If there is no golden finger like Zhao Ji, it is impossible for the airship to appear.

"Your Majesty, there are still some Wei ministers who can't believe that we can really make things that fly to the sky? In the past, everyone thought that this was the realm of the gods, and people who saw that they could fly to the sky would worship them. Today's people, they are all excited and happy, but they don't have the slightest idea of ​​worship..."

Zhao Ji nodded with a smile, yes, that's true, "This is a kind of progress, because everyone knows what's going on. If you still bow down stupidly, wouldn't you be laughed at?"

"To open up the wisdom of the people and educate the people, the university opened by His Majesty is truly a great achievement!" Zhang Shuye said sincerely.

"Now my Song Dynasty has undergone earth-shaking changes. There are two railways in the north and south, two railways in the east and west, as well as criss-crossed highways. Now the power of machinery has been greatly utilized, and the people live and work in peace and contentment, not only can they eat and drink enough. , I can also raise livestock to improve my life. I am satisfied when I see these! Zhao Ji came back this time and saw more changes.

As long as steam engines and internal combustion engines come out, people will see their great role, and they will flourish even without the impetus of the imperial court, let alone Zhao Ji's vigorous promotion of development. Nowadays, trains, large trucks and horse-drawn carriages exist at the same time in transportation. Because the speed of horse-drawn carriages is too slow, it is not allowed to go on the main road.

In the Song Dynasty, several main roads and some secondary roads were built, and there were no restrictions on secondary roads.

As the speed increased, the exchanges between the north and the south accelerated, and various goods began to circulate. Even some fresh vegetables could also be transported from the north to the south, which greatly prospered the economy of the Song Dynasty.

While talking, the airship lifted off.0

The airship flew higher and higher, and countless people in Yanjing City were cheering, watching the airship fly to a height of several hundred meters, and then flew towards the distance. At this time, the airship can not only rely on air drifting, there are two propellers behind the airship, which can push the airship to fly and change its direction.

When the airbag is filled with helium gas, the airship rises slowly. With the increase of altitude, the atmospheric pressure gradually decreases, and the helium gas in the airbag expands. Fortunately, they were also alert, and they quickly stabbed a small hole in the airbag with a knife before the airship safely landed on the ground.

After coming down, the two of them were still a little weak in their legs.

After several attempts, the airship must be deflated as soon as it rises to prevent the airbags from inflating and bursting. But after the gas is released, it can no longer rise.

Zhao Ji laughed when he knew about this situation, he had heard of this situation, and it had been resolved in later generations. So he said, "You can make a balloon with an air chamber like this.

Shaped like a spindle, this kind of balloon has a large silk capsule on the outside and a small air sac on the inside with a gas valve above it. The outer bag is filled with helium, so that the balloon rises into the air by buoyancy, and the inner bag is used to inflate air. This little air bag is called the "air room"

Before the balloon lifts off, the "air chamber" is filled with air. When the balloon rises to a certain height 3.2, the "air room" is opened to release a part of the air. In this way, after the outer bag is inflated, the "air room" shrinks due to being squeezed, so that the inflation pressure of the outer bag is reduced, so as to ensure that the air bag does not burst.

Wouldn't the problem be solved in this way?"

Saying that, Zhao Ji also drew a picture to help them understand.

These students have been troubled by this problem all the time, and they are all looking for a solution. When they saw this picture, they suddenly realized one by one, and they all looked at Zhao Ji in amazement and admiration.

"Your Majesty is wise and martial, we worship!"

Zhao Ji touched his nose. In fact, how could he figure it out? This is the common wisdom of many people. But, forget it, it can't be said.
