The time is inadvertently more than three months, the weather is already cool, and the fields are full of busy farmers.

Zhang Hao pulled Zhou Xueyao and stood under the lighthouse, overlooking the sea and the brand-new port. More looking at the busy and excited crowd down the hill.

More than three months have passed, and so many stories have happened.

The country of Qixia rose strong and dominated the West - except for the country of Zhongshan. After all, half of the country of Zhongshan was swallowed by the country of Taihua, and the relationship between the country of Taihua and the country of Qixia also began to be tense.

In this case, the country of green clouds also swallowed the other half of the country of Zhongshan. And between the country of Qingyun, the country of Taihua, and the country of Qixia, there is a three-legged posture.

It is true that the country of Qixia, which is busy rectifying the country, is not capable of continuing the war, and now the country of Qixia is the largest of the three kingdoms, but the country is in ruins, and the newly occupied areas need to be consolidated. Therefore, the posture of the three kingdoms is stalemate.

There are also the countries of Canglan and Langya, and now the war between the two countries is flourishing.

The two steel battleships that Wang Ruiyang took away were indeed sent to the country of Langya. The two warships were named respectively: Hailonghao and The Hague.

However, the ownership of these two warships still belongs to the Easy faction, and the masters on the battleships, and even many soldiers, are designated by the Easy faction.

However, the country of Langya can imitate these two warships, plus the technology obtained from the Ocean Group, and redesign and build its own warship, the Xuantie warship.

However, the country of Langya is not easy. In the past three months, the country of Canglan has ordered two steel warships from the Ocean Group again - the Ocean Group has sold two old warships, so that the country of Canglan has three steel warships. Except for the original 'Revenge', the rest were named 'Dawn' and 'Thunder'.

Relying on three steel warships, the Land of Canglan finally opened up the sea route again, trading directly from the southern part of the Emerald Sea, directly with the Continent of Torrential Earth, and indirectly with the Eastern fleet. In this way, the country of vicissitudes has finally come out of the trough.

Also, if there is a problem with the warship of the country of Canglan, you can directly ask the Ocean Group for maintenance. And something is wrong with the warships of the country of Langya...... Figure it out for yourself!

However, behind the country of Langya stands the free faction, so the country of Canglan is not easy.

In addition, the biggest thing in the past three months is the strong rise of the country of Shaoze, and the country of Shaoze, which has just risen, has picked a soft persimmon - the country of Langya!

The poor country of Langya was occupied by the country of Canglan for more than a thousand miles in the west, and there was a life-and-death duel with the country of Canglan on the ocean, and the domestic strength was already stretched, but I didn't expect a tiger to suddenly appear behind it, and the northern front suddenly collapsed.

The soldiers of the country of Shaoze have been sharpening their swords on their own land for more than 30 years, and with the secret support of the Ocean Group, the combat effectiveness of the legions of the country of Shaoze is beyond imagination.

In just a few days, the northern defense line of the country of Langya retreated more than 600 miles.

In the end, it was the direct intervention of the Xiaoyao faction that allowed the country of the Southern Tang Dynasty and the country of the Northern Tang Dynasty to jointly send troops, which temporarily curbed the madness of the country of Shaoze.

But in the war of the Land Legion, the country of Shaoze is too strong. The allied armies of the Southern Tang Dynasty and the Northern Tang Dynasty could only shrink back on the defensive most of the time.

Fortunately, the country of Shaoze has just been unified, and the country is empty, and Nangong Zhi's attack is actually to attack instead of defending, so he will accept it when he sees it.

But the sudden rise of the country of Shaoze still made the surrounding countries panic. The last thing that everyone wants to see is finally reunited again. And as soon as it appeared, the country of Langya retreated 600 miles! If it weren't for the effort, the country of Langya would have been driven into the sea to swim.

And the biggest impact is - industry and commerce, blooming everywhere!

Three months have passed, and the original information has already been spread everywhere. In the end, Dayang Group simply established a publishing house. The first printed publications of the publishing house were not newspapers, but technical materials.

Uniformly printed by Dayang Group, very exquisite technical information, a set of only one high-grade spirit stone. Including black iron smelting technology, steam turbine technology, shipbuilding technology, simple machine tool technology, sealing the sky and locking the earth array, and so on.

In these materials, new, standardized units are used.

However, in these materials, there is only finished product, raw and cold data, and there is no research and development process.

But even so, demand still outstrips supply.

After the Dayang Group re-established contact with the East, Hua An, the young master from Kunlun Zhizhou and the contradictory trading house, after seeing these materials, actually bought a whole shipload of materials, and did not ask for Xuantie, steel, etc., so he left in a hurry.

In short, in just three months, the technology has completely spread. In the south, the sea ships from the Ocean Group were sent to Storm Point, the southernmost part of the Turbulent Continent and belonging to the Heavenly Demon Sect, and naturally it was also sent to the Heavenly Demon Sect.

The easternmost has spread to the Kunlun Continent.

And in the Fertile Continent, at least in the West of the Fertile Continent, almost every country has established its own military industrial system - simple machine tools, dark iron production lines, and most importantly, artillery production lines!

The country of Qixia has changed the most, and the railroad has spread to the whole country - Liu Xinyu is keenly aware of the significance of the railway to rule. In addition to railways, there are also roads. Today's highways are still dominated by rammed earth. But there is already a little asphalt pavement.

The current country of Qixia has basically consolidated the territory of 15,000 miles, and Liu Xinyu has become the most powerful emperor in the history of the country of Qixia.

And large and small workshops, enterprises, groups, etc., are also blooming everywhere in the country of Qixia.

Especially the Red Mansion, almost all of the first-generation production equipment of the Dayang Group was bought, and a total of more than 100 million high-grade spirit stones were spent - almost all the family funds were emptied.

Now, the Red Mansion is happily carrying out its own large-scale construction - a complete industrial chain of Xuantie, artillery, and warships.

Under Zhang Hao's planning, under the guidance of Zhou Jue and others, Red Mansion was ambitious to complete an industrial system alone.

But the biggest change is the Ocean Group.

There is a way that the old does not go, the new does not come, and the current Dayang Group is thriving. I don't see the impact of the disaster at all.

At the beginning, the biggest impact was the port, the warship in the port, and the dock. Among them, the battleship is Xuanzhenjiao, and the dock and port are a little old, and they have long wanted to be dismantled.

Today, Zhang Hao is looking out over his shipyard. No one knows that in the new dockyard, the technicians and engineers of the Ocean Group, are building new warships - with a displacement of 20,000 tons!

The maturity of welding technology has made all this possible.

Huang Mingshan and others have now developed a new kind of power machinery -- the internal combustion engine!

But today, Zhang Hao and Zhou Xueyao are here to watch, and the main items are...... Balloon!

After nine months of preparation and exploration, the first real hot air balloon that can carry people has finally appeared.

Today is the date of the first public test of the hot air balloon.

Zhang Hao and Zhou Xueyao stood side by side, and countless people around them were looking forward to it. Those who are here today are all insiders - at least they are told that something new is coming up today, an object that flies without relying on spells.

In a world of practice, if you tell someone how something works without spells, that's quite eye-catching! It's the same as the concept of a sudden spell in a world of technology.

Although the Ocean Group has had many miracles, the flying things still attract many eyeballs.

How can you fly without relying on spells? Is it like a bird?

In the midst of all the attention, Murong Shan, who had just joined the Dayang Group for three months, came with a group of people, Murong Shan took the lead, and everyone behind them carried various tools, and even a two-meter diameter large frame made of steel bars and wires, sandbags, rolled up colorful airbags, and so on.

Further back, there were several young men in white, simple robes, led by two eighteen-year-old girls.

These two girls are the maids beside Zhou Xueyao, Xiaozhu and Xiaoyue. But now, these two girls have become scientists of the Ocean Group.

The two daughters were originally young daughters sold by poor families, and they were bought by Xinglintang. Now he also has the surname Zhou, which can be regarded as having a complete name.

studied chemistry with Zhou Xueyao, and by the way, he came into contact with physics, etc., and finally took on Zhang Hao's appointment and research hot air balloons.

Finally, it's time to make a name for yourself.

Suddenly, more than 200 people flew in the direction of the Zhang family's compound. These people are dressed in different ways and styles. These people have all joined the Dayang Group one after another.

Some of them were attracted by the theory of the circle of the earth, some by science and technology, some came for the great voyage and the legendary overseas Nine Immortal Mountains, and some came because of astrology......

These people come from all over the world, but they all have some real skills, and most of their cultivation is above the Yuan infant stage, and there is no shortage of late and peak ones; Zhang Hao has selected more than 200 people after repeated selections. More of them, for the time being, they can only live in the country of Qixia.

Everything was ready, Xiaozhu and Xiaoyue came to the center of the field that had been demarcated and began to command.

Murong Shan, a great master and general, was turned around by the two little girls, and things were assembled in a short time.

A dozen meters long airbag crawls on the ground and extends down the hillside to a high place - this makes it easier to inflate.

Xiaozhu Xiaoyue commanded, Murong Shan and Murong Shan's men (brought from the north) poured naphtha into the burner according to the command of the two little girls, lit it and then the burner spewed out flames. After adjusting the distance, the hot gas of the flame rushes into the air bag.

Gradually, the bottom of the airbag began to inflate and bulge. As the speed increases, more hot gases enter the airbags, which expand and float at a speed visible to the naked eye.

There was a sound of 'oh ......' around the area, and everyone was very curious but surprised...... But not much. In the world of cultivation, there are too many strange things that everyone has seen.

The colorful airbags gradually became round and rolling, the flames were burning, and the hot air entered the balloon.

Suddenly, the basket moved.

"Throw sandbags!" shouted Xiaozhu.

Murong Shan began to throw sandbags, and the hot air balloon swayed gently and began to rise. And Murong Shan had two more people, standing in the basket.

This time, exclamations erupted all around.

Really didn't use spells to fly?

How does this work?

The balloon flew higher and higher, surpassing the first layer of white clouds and the second layer of white clouds. until the thin, sturdy rope that pulls the hot air balloon is taut. At this time, the mark on the rope is - 20 km!

From the ground, the hot air balloon at this time has only a small black dot left, which is obscured by the white clouds in the sky from time to time.

On the ground, Xiaozhu explained in a loud voice: "This is the new technology of the Ocean Group, which we call a hot air balloon." The principle of its lift-off is to take advantage of the phenomenon of upward smoke gas!"

Well, don't expect the Ocean Group to disclose the real principle, it's definitely not worth your life. But then again, smoke rises...... Nothing wrong!

Xiaozhu continued, "At the moment, this is just a technological exploration. In the future, we are ready to build super-large hot air balloons. We envision that the balloon will be more than a kilometer in size, and it will be able to transport hundreds of tons of cargo at a time, directly through the sky.

Compared to a flying boat, it will be slow and bulky. But it's going to be very low. The volume of transport is higher, and even the army can be transported!

Do you know how much this hot air balloon costs?"

After a short pause, Xiaozhu said, "The cost of this hot air balloon is 300,000 yuan! If the technology is mature, we are confident that it will be compressed to less than 150,000 yuan!"

300,000 yuan is the price of 30 medium-grade spirit stones!

And the cost of a flying boat is tens of thousands of top-grade spirit stones!"

The eyes of many businessmen around lit up in an instant! They saw the value of the hot air balloon!

(Finally rushed out of the fourth shift before the early hours of the morning.) Thank you for your support, Tianya has worked hard...... ）
