[Modern large ships do not seem to need keels, but in fact, the keel has been changed into longitudinal reinforcement members at the bottom of the ship, less than six or seven, more than a dozen or even more, reinforced by ribs, combined with watertight cabins. But it's not that there is no keel. 】

At night, the port of Dayang Group is busy. To be exact, it's been so busy.

There are only seven days left before the end of the protection of the Xuanzhen Sect. Just when the Dayang Group held a general meeting of shareholders, the Xuanzhen Sect announced the results: in the early morning of seven days, the Hongyunzi of the Xuanzhen Sect will leave the country of Qixia, and the protection of the country of Qixia by the Xuanzhen Sect will officially end.

The news spread, and there was an uproar.

And the Ocean Group responded - start preparing for war now!

The battleship was equipped overnight, and in the early hours of the morning, Ding Kui arrived with 180 Yuan Infant Corps and boarded the ship overnight.

At noon the next day, under the watchful eye of the public, the battleship set off. According to the plan, the battleship would first sail south, completely out of sight from the ground, and then turn to the north, drifting on the sea for six days.

By the early morning of six days later, that is, the moment when Xuanzhen Sect Hongyunzi left, the battleship would rush to the shore of the Yanyun Country, and the master would begin to land and fight.

This time, it was a surprise.

Killing the country of Yanyun would not have imagined that the country of Qixia would have such a crazy strategy. Six days in advance, it was floating on the sea.

At noon, watching the battleship leave the port, everyone subconsciously thought that the battleship continued to go south and continue to go to the Taotu Continent to do business.

In fact, no one thought that in full view of everyone, Dayang Group was acting!

Putting everything in the sun creates the effect of darkness under the lamp.

Even Lu Xuanyu, the warship leader of the Xuanzhen Sect next to the port, didn't expect it. He also greeted Dugu Junjie and Shu Bennan, the head of the royal fleet of the country of Qixia. Still asking: Where are you going this time?

"I'm going to go to the place of the Heavenly Demon Sect again. Dugu Junjie responded without blinking.

And on the battleship, there are Liu Dingshan, Chen Yansong, and Fu Yun. As for the couple of Sword and Sword Heroes, they stayed in the country of Qixia just in case.

At the same time, the country of Qixia also began to deploy troops on the border, and when the moment came, they were ready to take the initiative to attack - only if the country of Qixia made the appearance of taking the initiative to attack, they would not think much about it.

In the evening of that day, in the barracks, Wu Fanghai received a batch of brand new artillery. This is a batch of 160 mm caliber guns. In the past, the rapid development of the Zhangjia and Dayang Group also led to the shortage of artillery calibers, which seriously affected the flexibility of the army.

At that time there were only three calibers, 100 mm, 300 mm and 460 mm. Among them, 100 mm and 300 mm can be used on land. And 300 mm is already very bulky.

Today, the production of 160 mm caliber has finally begun. The power is impressive.

And most importantly, the new artillery range reaches: 40 km!

Wu Fanghai looked at the technical data and looked at the engineers of the Ocean Group with some surprise, "The range is 40 kilometers?

The engineer smiled, "General, rest assured, the maximum range of our practical tests, up to 46 km." 40 km is the recommended range. After more than 40 km, the shells will drift. ”

Wu Fanghai looked at the information and said for a while, "The first artillery has a range of 10 kilometers, and the second has a range of 20 kilometers. This third almost 40 km is an improvement. So the next artillery range, is 80 km?"

"This ...... I'm afraid not. We plan the next generation of artillery range, which is planned to look at 60 km. The range of 40 km is already approaching the temporary technical limit, and it is difficult to double it.

However, the theoretical limit is said to be up to 120 km. (Note (1))"

"The difference between the actual distance and the theoretical limit is so big?"

"General, the actual range of shells is associated with a lot of factors. For example, weather conditions, wind direction and speed, such as air density, and the design of the artillery itself.

Also, new artillery technology, increased formation and aura capabilities. How far the cannonball can fly is also related to the formation and aura.

At present, the aura and formation attached to the cannonball can only run for about a minute. In one minute, the shell can fly exactly 40 kilometers or so.

Beyond 40 km, the formation will fail, and the shells will begin to drift.

So the new artillery, I need to explain something.

The medium-grade spirit stone inlaid on the barrel is used to stimulate the formation of the cannonball. Due to technical limitations, the formation needs to be activated manually before the shells are fired. At least six layers of cultivation in the Qi refining period are required.

A medium-grade spirit stone is expected to fire 100 cannonballs. It can be replaced with a high-grade spirit stone, the effect is better, but the improvement is not large. It is not recommended to replace the lower grade spirit stone.

New shells also need to be moisture and waterproof. ”

............

When the country of Qixia was preparing for war, the withered Qianlong Port port of the country of Canglan, the emperor of the country of Canglan saw the steel battleship slowly approaching with the support of everyone.

This was the first time the Emperor had seen a steel battleship with his own eyes, but he was hooked at first sight.

"Good!" the Emperor excited.

Because of the technological upgrade, the battleship's artillery adopts a simple turret and a single turret, which is not the mature twin turret of the Dayang Group. However, a single turret is sufficient.

And in the bow there are two 460 mm and two 300 mm guns. Powerful. Depth charge towers and ballista installations have been added to the ship's side. But there were no guns.

When the agreement was signed, it was the technical level of the 'Iron Duke', and the Ocean Group upgraded the lower fort and added a depth charge launch tower, which was enough to be righteous.

Not to mention, it also helped train the navy. A steel battleship with a total of 1,200 people. The captain of the ship and the future commander of the navy is Ning Hu, who is the blood of the royal family.

From afar, I saw that on the bow armor of the battleship, there were three large words of "Revenge" shining brightly, milled with a machine tool.

The Great Emperor boarded the battleship, inspected it for a long time, and finally asked Ning Hu, "How is the combat strength now?"

"Your Majesty, Dugu Junjie of the Ocean Group said that our current combat effectiveness is comparable to the combat effectiveness of the Ocean Group when it went to sea for the second time. ”

The Emperor thought for a moment and asked, "Then how about attacking the country of Langya now?" We are close to the country of Langya here, and we will run away after the fight." On the sea, our Transformation Period will pass to intercept their masters.

In a few days, Hongyunzi of the Xuanzhen Sect will withdraw from the country of Qixia and come to us to assist us in the battle with the country of Langya.

You rest for a few days. Get ready for battle!"

"Yes!" Ning Hu's eyes brightened. Now that this powerful steel battleship has been bought, it must be used!

............

At this time, the five western countries (the country of Yanyun, the country of Zhoushan, the country of Zhongshan, the country of Jinyang, the country of Danyang), plus the country of Qingyun, began to be restless.

It is said that the country of Qingyun does not belong to the series of the six western countries, this country is located in the northeast of the country of Zhongshan, east of the country of Yanyun, north of the country of Taihua, and the war of the six countries in the west has nothing to do with his country of Qingyun.

But there are also smart people in the land of green clouds, and they are ambitious and greedy:

The prosperity of the country of Qixia caused them to be vigilant - they were worried that once the country of Qixia accidentally killed the rest of the countries, the country of Qingyun would be angry;

In addition, they are also greedy for the technology of the country of Qixia and the wealth of the country of Qixia.

Therefore, the country of green clouds quietly joined the other five countries. Invisibly, the country of Qixia needs to face the pressure of the six countries. And the power of the country of green clouds is comparable to the country of canglans!

As night fell, in the main hall of the country of green clouds, the monarchs and ministers were discussing the war situation.

Everyone is full of confidence, and they all think that even if the country of Qixia is strong, but under the joint efforts of the six countries, it is just an egg in front of the stone, which is a goose egg!

In the main hall, there were also representatives from the other five countries. Before the war began, everyone was discussing the division of interests. As for tactics...... Is it still necessary to discuss, several countries sent troops on all fronts, and there was no need for tactics at all.

"Technology can be replicated. Talent is divided according to the contribution of each country in the war. ”

"The empress of the country of Qixia is good, I want the country of Yanyun. ”

"I heard that Zhang Hao's fiancée Zhou Xueyao is very beautiful, and there is Xinglintang behind her. If you can take down this woman, it will be equivalent to taking down half of Xinglintang. I have booked the country of green clouds! Maybe I can give her a crown princess in the future!"

"The alchemists of Xinglin Hall, we want to divide them equally!"

......

The Emperor of the Land of Qingyun sat above, smiling and watching everyone arguing.

Now among the six countries, the country of Qingyun is the strongest, the country of Yanyun is second, the country of Jinyang is again, and then the country of Zhongshan. As for the country of Zhoushan and the country of Danyang, they were both crippled by the previous war, and the two countries together can top a country of Jinyang.

Now the legions of the Qingyun Country have begun to prepare, and they may send troops and enter the battlefield of the Qixia Country at any time.

The Emperor was smiling, as if he had seen a brilliant future.

While they were discussing, a Praetorian guard came quickly, holding urgent information with black skins in both hands. Black, extremely dangerous!

The emperor's heart jumped, and when he took the information, his face changed instantly.

The hall fell silent for a moment.
