The lightest ones that can be counted as rail guns are over 30 tons, and can only be installed on warships over six generations. This is also the reason why warships of the fifth generation level have been eliminated one after another.

As for the top-level rail guns of hundreds of tons on both sides, neither side can streamline them at present, so they are trying to redesign them.

However, as of now, it seems that both sides will not be able to achieve results in a short period of time. By the way, Rome has not followed up on the idea of ​​naval guns, because as of now, Rome has not realized how far the Han army and the Kushan navy have evolved.

It is estimated that after the observation team arrives, it will not take long for Rome to push the naval guns like a mad dog. After all, the navy has developed to this level. The army that is near the sea is almost the same as playing. After the kinetic energy weapon is opened, even with cloud protection, a large pit of more than ten meters in radius can be created with one shot, which is almost far beyond the army's understanding of conventional strikes.

The problem is that attacks of this level are just like Ping A for the Navy. Zhou Yu's entire ship's volley can be counted as the turret, and the starting power of this level is the power of this level.

Therefore, after the Roman observation team finished watching the new version of the naval battle between the Han Dynasty and the Kushans, they would probably follow it. After all, if the empire does not take the initiative to roll it up, they will be killed by others.

Rome was a little bit aware of danger in times of peace. Seeing the terrifying caliber of the Han army and the Kushan, I would probably develop the fort at a loss. After all, the Han Dynasty and the Kushan can be said to be continentalism, but the Mediterranean bathtub in Rome...

Seeing the terrifying attack method of the Han army and Kushan Ping A being able to blow up a camp directly, the Roman Empire would not have been worried that these two sides would kill the Mediterranean and use the Mediterranean as a battlefield. As for allies, nonsense, the empire’s alliance letter was maintained by strength, not by paper.

Accompanied by Meng Kangbu's order, a single shot of energy-beating arrows was soon filled into the turret. After the elite backbone was operating the turret, it fired towards the direction of the Han army when its power was accumulated to its maximum.

This time the spear that was shot out turned into a light spear as soon as it broke off the track, and it blasted fiercely at the frigate behind the hall with a ball of light.

"Boom!" With a series of roars, the Kushan crossbows' strike technology was very problematic, and the hit rate was basically less than 20%. Therefore, many light spears fell directly into the sea, and blasted out water columns dozens of meters high...

生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生生�

This terrifying power was learned by the Han army's secret reconnaissance technique, and was quickly entered into the secret magic mirror, and then transferred to the accompanying personnel to quickly obtain the power of the Kushan new artillery shells based on their experience and calculations. Without waiting for the calculation results to arrive at Ganning, a huge roar appeared behind.

"The frigate No. 4 was hit, and the outside was damaged. The overall deflection was 16°, and there was a danger of a shipwreck." Huang Gai's centurion loudly notified Gan Ning.

"Use the main gun to suppress it and order the crew of the frigate No. 4 to transfer." Gan Ning ordered with a calm expression. The worse the situation of him, the calmer he was.

"The main gun has been filled, but the hit rate cannot be guaranteed." Cheng Pu personally flew over to notify Gan Ning, "More importantly, after using the main gun, Mengkangbu may continue to chase us, and we do not have the ability to fight against Mengkangbu now."

Although Cheng Pu has a bad temper, he has recognized the reality after fighting so many naval battles. These days, Selian and Zhou Yu are T0, Mengkangbu T0.5, Gan Ning and Sesi Sagli T1. The remaining young people from the Sesi family can rank in the number, and they can only be considered deputy.

Therefore, when facing Meng Kangbu, Nikaya, Bebto and Aruno, Cheng Pu also rationally chose to run away. There was no way. Without Zhou Yu's combat power, everyone had to kneel down when they met such a large group. Half of the reason why they could withstand it was because Meng Kangbu did not do his best, but just held the idea of ​​the Han army he met.

But if the electromagnetic-Tiandi Essence Hybrid Rail Cannon is exposed, Meng Kangbu will definitely choose to chase and fight.

Because the Han Dynasty equipped with main guns of this level are definitely flagships. Although Zhou Yu is very rich and powerful, all the seventh-generation ships have been developed, not every seventh-generation ship is equipped with main guns of this level.

Although the situation in the Han Dynasty was not as scarce as that of the Kushans, with only six super main guns, Zhou Yu was not rich enough to install a super gun that could only several rounds of hammering and blowing a full defense seven-generation ship.

Therefore, after hitting this thing, Meng Kangbu on the opposite side was basically sure that the fleet he encountered occasionally contained the flagship of a Han army fleet, and was sure that there must be big fish in it. At that time, Meng Kangbu would never fight with a hammer to death.

"Let Sun He go, General Cheng, you use your legion talent to cover Sun He, so that he can maintain his peak performance, overload the main flagship, and shoot continuously." Sun Ce glanced at Cheng Pu and directly issued an order on behalf of Gan Ning. Although the naval battle between Sun Ce was not good, Sun Ce's intuition told him that even if you don't use the flagship's main gun, Meng Kangbu would never let this fleet go.

"Yes!" Cheng Pu did not say a redundant word when he received Sun Ce's order, and rushed directly to the deck. After Sun He received the message, he also rushed straight to the main gun position.

"Boom!" Another loud bang, two luminous spears hit the frigate behind the fleet at the same time. The already-destroyed frigate could not withstand this time. A huge crack was made at the waterline. As the sea water poured in, the frigate obviously tilted and began to sink.

"Activate the observation technology of the middle cabin and show me what is going on with this frigate that is about to sink!" Seeing that the frigate sank one, Meng Kangbu ordered decisively.

You should know that the attack weapon is such as betting and arrows. Although it is not as good as the main gun, it can also cause a high-destructive weapon to cause certain damage to the Han army flagship after Zhou Yu fully activated the group's defense.

As a result, a mere small boat was sunk after several bets of arrows. Meng Kangbu was surprised if he was confused. As for the time he came to salvage the wreck, to be honest, Kushan was really unable to do the depth of the Indian Ocean.

Soon, the observation secret technique of the middle cabin relied on the high-level Xintong to pass on the details they saw to Meng Kangbu. When he saw the broken gap of the shipwreck, Meng Kangbu fell into silence. Even though the Kushan generals and schoolmen had seen this small boat blocking a lot of shelling, due to reality, most generals and schoolmen did not dare to think about the steel structure.

However, when they really saw the materials used by this soon-to-sinking frigate, all the Kushan generals who were qualified to see this thing understood why this thing could block such a bombardment.

The ordinary ship's volley can be carried directly by the small boat on the opposite side. The reason is very simple. This thing is all steel structure.

Just like when the previous dreadnought encountered the dreadnought, it directly opened up the generation gap. The Kushan was able to explode this frigate. It can only be said that the displacement of this frigate is too small. If it was replaced by the same level of displacement, it would be a joke to use all means.

The captains who were qualified to see this scene were all silent at this moment.

There were no special secret techniques they thought of, nor were there any hard wood that they cherished. It was not because the Han Dynasty's cloud defense structure had made great progress, but because there was enough simpler and more direct steel.

Mengkangbu was silent for a long time, and even Aruno, who was standing beside him, stopped commanding. Fortunately, the group's defensive style had been arranged. Relying on the special defensive structure, the Han army's not too high hit rate did not cause much damage to the Kushans.

"Chasing." After a long silence, Meng Kangbu finally reacted.

Aruno nodded, but both sides were no longer as confident as before at this moment.

Warm-raising can greatly strengthen the material. After warming, ordinary wooden weapons can even catch up with and catch up with the top steel that has just been released without warming.

In this way, the meaning of steel seems to have completely lost its value. However, steel can also be warmed. The so-called warming cannot change the essence of the material. It is just a kind of strengthening. Materials with high strength will have higher strength under the action of warming.

The wooden gun does not penetrate the plate armor, and the wooden guns of the same level of warm-up cannot penetrate the plate armor. The wooden ships cannot collide with the steel ships, so the sail battleship fleet with a defensive structure attached to the warm-up cannot collide with the dreadnought with a defensive structure attached to the warm-up.

The navy is a kind of vehicle-eating military. When there is a significant gap in vehicle, the commander cannot disobey the general trend. What's more, speaking with his conscience, everyone knows that Zhou Yu is truly invincible in the sense of the world.

The Kushan Navy can still fight now, because it is because there are also the backbone of the Sisi family, the veterans left by Selyan, as well as enough skills and special cloud air secret techniques, but the frigate that the Han army appeared on the ocean this time completely made Meng Kangbuma.

At this moment, the naval commanders such as Monkamp, ​​Aruno, and Bebto, who were on the front line of the world were like seeing Zhou Yu defeating Selian and completing the alternation between the old and new kings.

At this moment, Aruno, Bebto, and Nikayaya also understood why Mengkangbu called Zhou Yu the devil of the new era, rather than the brave one who defeated the great devil, because the rule brought by each generation of devil kings is completely different.

Cellian is a cloud gas architecture, a cloud gas solidification path, a group defense, and a technology and tactics.

Zhou Yu is a giant ship and cannon, a super-large-scale enemy hunt, and a dreadnought, which is a tactical innovation.

"He may really be the devil." Aruno said with silence.

Starting from Aruno following Selian, he witnessed the rise of an invincible commander. Even if he lost before, Aruno believed that it was not Zhou Yu's strong, but Selian was old. Having seen Selian who was traversing the Indian Ocean when he was young, Aruno knew very well that Zhou Yu had not surpassed him.

However, when he saw the Han army's frigate being sunk by Kushan, Aruno finally realized that Zhou Yu and his fleet were definitely qualified to fight against Selyan's peak.

"Even if it is the Demon King, we can't look back." Meng Kangbu said in a breath, "After I go back, I beg your Majesty to try to advance..."

However, as he spoke, Mengkangbu was silent because of steel production and shipbuilding technology.

Both of these are unsurpassable gaps. Not to mention the steel output, the Kushan picked up the Brahmins' caste division of labor. After arming the army, the steel output could barely squeeze out thousands of tons.

The problem lies in shipbuilding technology. Chen Xi admitted that Kushan's shipbuilding technology is definitely the best in the world. Even if the Han Dynasty is working hard to develop in ordinary wooden large ships, it will be difficult for him to distance himself even if he catches up and surpasses Kushan.

After all, the peak of wooden warships is actually sail battleships. In history, the displacement of this thing can reach nearly 10,000 tons. After reaching this level, it will become extremely difficult to make every point of increase.

Structure, frame, material strength, counterweight, etc. will all become extremely fatal.

Just like when the efficiency of a steam engine reaches a certain level, it is difficult to improve, and when the piston engine reaches a certain level, it is difficult to break through a certain efficiency point. Many things are already close to the upper limit after a period of rapid development, and it is difficult to have qualitative changes.

This is true for wooden sail battleships. Even if the Han army is developing for life, the upper limit cannot be tied to the Kushan level. The opponent can still rely on weaker technology to fight against each other, and there is no obvious generation difference.

If it is replaced with a steel warship, it would be different. Even if it is the most flawless ship, it is a dreadnought, and it can crush the warships before the fearless.

More importantly, there are no opponents on this road, and the Han Dynasty is the absolute first start.

Even if Kushan discovers it now, it is impossible to catch up. Just a qualified steel plate resists rust and deformation, is enough for Kushan to collapse rationally.

Chen Xi spent countless resources and failed countless times. Finally, he improved the theory of the seventh-generation ship little by little by little with repeated verification.

Lu Jun made the model and thought that he could just zoom in year-on-year with the model, but in fact, whether a certain structure uses riveting, casting, brazing, spot welding, forging welding, or other methods, is enough.

And this is just a very small point among countless problems.

To be honest, the keel that Gan Ning saw for the first time at Donglai Shipyard had already collapsed. To put it bluntly, the entire seventh-generation ship was a repeated trial and error process.

Lu Jun has a stubborn side and really wants to create such a thing. So after failing hundreds or thousands of times, when Chen Xi went to Donglai Shipyard for the last time, the seventh-generation ship really had hope of being built two years ago.

It is no longer a progress that stays on paper forever, but a real hope.
