The facts once again proved Xiao Letian's bad taste, and it was actually a hot air balloon that rose from the south of Osaka Castle!

The history of human use of hot air balloons can be traced back to the 18th century, and after more than 100 years of development, hot air balloons have begun to be used in the military field.

During the American Civil War and the Austro-Prussian War, hot air balloons were used as a means of battlefield reconnaissance, but because the impact of hot air balloons on the weather environment was too strict, the army did not use them on a large scale.

Xiao Letian was the first person to bring the hot air balloon to Asia and show it, at the Forbidden City Dynasty Meeting, the secret weapon that finally appeared in the finale to deter the entire Sijiu City was the hot air balloon, that is, that flight, which made the heart of Emperor Tongzhi completely wild.

At that time, the well-informed masters of Jing in the entire Sijiu City were all dumbfounded, kneeling on the ground and kowtowing desperately, thinking that the gods were coming.

At this time, the Japanese people were even more ignorant than the people of the Qing Dynasty, and when the huge hot air balloon began to approach Osaka Castle in the air, everyone knelt on the ground and shouted the names of gods and Buddhas in their mouths.

"What is this? What kind of god is that in the sky! Look, the gods are smiling at us......

That's right, there was a strange creature smiling at everyone in the hot air balloon, it was a blue tanuki with a round head and belly, and even round hands and feet.

There was a brass bell around his neck, and there was a big pocket on his white belly.

Xiao Lotian couldn't laugh straight, this is a joke that only he can understand, because the planet on the hot air balloon is the famous Doraemon in later generations!

Bad taste, it's really bad taste, today Xiao Lotian is going to make Doraemon a nightmare for the Japanese, and Doraemon will become a god who punishes Japan.

Two intelligence officers in the gondola are looking down from the sky, one of them adding coal and shaking a blower, while the other intelligence officer is waving red and yellow flags and sending flags to the fleet.

The flag handler on the Roma quickly translated "due north at eleven o'clock...... The muzzle elevation angle is forty-five degrees...... Triple Burst Intensive Bombardment ......"

With the order, all the guns on the right side of the Roma began to adjust their angles, and the high-explosive shells were loaded in the barrels, and with the pull of the ropes, the muzzles rumbled, and smoke and fire sprayed on the sea.

The Tokugawa ministers in the castle tower of Osaka Castle watched the cannonballs whizz overhead, drawing a perfect parabola, and exploded directly into the military formation of the Tokugawa New Army.

"No...... What's going on? What the hell is going on? They can't see the situation on the battlefield, but why did they blow up so accurately?" Tokugawa stumbled and fell to the ground.

On the distant plain, although only twelve shells of twenty huge explosion points fell into the crowd and caused effective damage, the power of the high-explosive shells was too great, and after twelve violent explosions, the formation of the three companies was completely destroyed.

The telescopes of the Sieduo and the French minister on the southern hill fell to the ground, "What? Xiao Letian actually has such an elite gunner? Damn, these Asian yellow-skinned monkeys, when did they learn trigonometry and calculus?"

It is not wrong at all, when artillery technology developed to the age of rifled guns, the flight trajectory of the shell was not parallel, but rotating. This way of flying makes the trajectory of the shell very stable, and the accuracy increases exponentially.

In the past era of smoothbore guns, there was always a small gap between the shell and the barrel, and when the gunpowder exploded, the strong thrust made the shell collide back and forth in the barrel, so that it would produce an unpredictable deviation at the moment when the cannon was discharged, that is, a deviation of one or two millimeters.

When the millimeter deviation of the muzzle of the gun is on the battlefield, it is an error of ten or even tens of meters, so the ballistic trajectory of the smoothbore gun is not measurable.

But rifled guns solve this problem, the rifling is like a small cutter to cut into the skin of the shell, so that the shell forms a rotating force, such a way of flight ballistics is very stable, since it is stable, then there is a place for mathematicians.

Artillery does not need to look at the battlefield visually, they only need the forward observation post to provide them with a variety of data, and then after a simple trigonometric calculation, people can adjust the muzzle attitude.

Now Xiao Lotian is playing this trick, the Japanese can't understand it, but the French are all human spirits, and they know at a glance that Xiao Lotian has mastered the most advanced artillery technology in the world at that time.

"Oh my God! Why did you let such a monster appear in Asia, it's only been a few years! He can catch up with this, what can he do in the long run? Europe's advantage will be gone!"

Minister Rosh has already made up his mind that when he returns to Europe, he must visit the kings of various countries, he will tell the interests and harms, and he will unite the whole of Europe to destroy Xiao Letian, the great enemy.

Xiao Letian laughed enough, he stretched out his hand and pointed to the hot air balloon in the sky and said, "That is our battlefield observation post, as long as he is there, even if our fleet has a pair of God's eyes, we don't need to use the Marine Corps at all, and today's battle artillery can be rounded!"

Next to him, Luo Huo said sourly, "Hey...... The credit was taken away from them...... If I had known this, I might have signed up to join the Navy in the first place!"

Xiao Hexin glanced at him, "It's just you, the navy is a technical branch, if you are not proficient in Western arithmetic, even if you are given a warship, you will not be able to command it, you will have to read more books a long time ago, you just don't listen......"

Xiao Lotian didn't have time to take care of his subordinates' bickering, he climbed the high platform behind the Second City, and used binoculars to observe the battlefield, and at this time, on the sea, the three battleships of the Roma, the Lyra, and the Wave Breaker had already adjusted their attitudes, and there were forty-six guns roaring in every salvo.

Matsudaira Rongbao in the distance was already stunned, he couldn't understand how the cannonballs on the sea were like eyes looking for his own military array bombing, what was that blue balloon in the sky, what was that terrifying and grinning monster?

"Heavenly punishment! This is heavenly punishment...... The order is to speed up the pursuit and entangle with the enemy, or we will be blown up sooner or later......"

However, no matter how fast the two legs were, the number of destroyed companies skyrocketed, and the morale of the Tokugawa New Army was on the verge of collapse.

Xixing Longsheng and Shan County Youpeng have now converged, they have looked stupid, everything in front of them is beyond their imagination, this new battle mode is something they have never imagined.

"Did Xiao Lotian do this? How did he do it? Why didn't I see a single Ryukyu soldier? Saigo-kun, what the hell is going on?"

"I don't know, I don't know what's going on, but there is only one person who can walk and create such a miracle, and that is Xiao Letian...... We had tried our best to guard against it, but in the end, we let him intervene, and once this strongman stopped in Japan, it would be difficult for us to send him away......" Saigo Takamori thought for a moment and suddenly shouted.

"Please Ryoma-kun Sakamoto come here, please!" After a while, Ryoma-kungfu Sakamoto ran all the way with gauze hanging from it.

"Ryoma-kun, please tell me what it is, and what happened on the battlefield?"

"Hai ......" Ryoma Sakamoto bowed slightly and said, "The sky should be flying in a hot air balloon, I heard about it when I was in the Ryukyus, this is a Western aircraft that can carry people to the sky, please see if there is a hanging basket under the balloon, there are people on it!"

The two took a closer look at the afterglow of the sunset, and sure enough, there were really two people busy with something under the terrifying hot air balloon.

"Judging from the density and direction of the current artillery fire, these shells are all pouring from the Ryukyu battleship, and it should be the Roma, Lyra, and Wave Breaker captured by Xiao Letian, as expected......"

"That's enough! To get to the point, I want to know why Xiao Letian's artillery can bypass Osaka Castle and hit so accurately!"

"It should be the people in the hot air balloon who send a signal to the fleet, and then the gunners of the fleet aim in the direction according to the signal...... That's all I know, this should be the latest war technique in Europe, and it should be an unpassed secret in the hands of Prime Minister Xiao Cheng!"

"The secret that is not passed on?" Shan Youpeng's eyes erupted with flames, and his right hand unconsciously held the handle of the knife, full of murderous aura.

"Don't pass on the secret! This is Xiao Letian's attitude towards his allies? Would you rather watch us fail than hide your secrets? I think he deliberately wants us Japan to lose both! And after all, you Sakamoto Ryoma has his Xiao Letian's blood on his body, no wonder you will give Tokugawa Qingxi what eight strategies in the boat, you just want to profit from both sides, and in the end you and Xiao Lotian became the last fisherman!"

Sakamoto Ryoma never imagined that his loyalty would be exchanged for such a big suspicion in the end: "Yamagu-kun! My loyalty to the emperor is visible every day, you can kill me, but you must not insult me!"

"Yaga!" Yama Prefecture Youpeng drew his sword and was about to attack Sakamoto Ryoma, but Sakamoto Ryoma was not the commander of the light pole, and the members of the sea aid team immediately rushed up to protect him. "Yaga, do you want to fight? The battle situation has reached such a difficult point, and you still have to fight among yourself!" Saigo Takamori was furious, his forehead was bruised, and his anger suppressed everyone present.

Yama Prefecture Aritomo and Sakamoto Ryoma both realized their gaffes and quickly bowed and admitted their mistakes and took a step back.

Saigo Takamori bowed to Sakamoto Ryoma at this time and said very sincerely, "Ryoma-kun, the current battlefield is no longer something I can understand, I hope you can teach me!"
