Haize Yushu saw four Chinese airships escaped, and he couldn't catch up, so he immediately returned, and when he returned, he happened to pass through Macao, at this time Macao has been developed and built under the rule of Lin Fei for more than a year, although it is not as prosperous as Dayu City, at least it is much stronger than the Qing State across the street, from the sky, Macao and Qing Kingdom are simply two worlds.

Yuki Hayazawa looked at Macau below, a vicious light suddenly flashed in his eyes, and he ordered with a wicked smile: "Aim at Macao below, shoot cannonballs at me, and use up all our cannonballs, and kill as many pigs as you can." ”

The deputy captain hurriedly persuaded: "Captain, it's not good for us to do this, launching an attack on the civilians in Macao will greatly irritate China." ”

Yuki Hayazawa said nonchalantly: "What are you worried about, our air attack on Macao, this account will eventually be calculated on the head of the Qing State, and we will not have anything at all." ”

The deputy captain suddenly realized, and Yuki Hayawa shouted excitedly: "Imperial warriors, let go and slaughter the Chinese pigs, the revenge of the Nanyang World War will be avenged today!" ”

The crew of the Japanese airship broke out into a burst of cheers, aimed the muzzle of the Grimm Gun downward, pulled the trigger, and the shell shot to the ground, right on the heads of the Chinese people.

How could the Chinese people have thought that the cannonballs fell from the sky, and a large number of people were killed in an instant, and the others scattered and fled in all directions, hiding in the house, but the cannonballs falling from the sky were extremely fast, and the thin roof could not stop them at all, and the shells pierced the house, killing all the people in the house.

The Japanese soldiers on the airship laughed loudly while firing the cannons, saying "all the pigs are going to die", turned the muzzle of the cannon, and chased the fleeing people with cannonballs, as if driving away a large flock of chickens and ducks.

The Japanese airship ran out all the shells, and then returned to the camp, the camp of the Japanese airship was in an open space on the outskirts of Guangzhou, because the Japanese airship was not transferred for a long time, so there was no time to build a garage, so the Japanese airship was stored in the open air, and when it was stored, it was fixed on the ground with a few anchor chains.

Because the gas filled in the airbag of the Japanese airship is hydrogen, so the Japanese airship does not dare to release the gas after landing, once it is released, there is no place to replenish, in this era to produce pure hydrogen, it still costs a lot, the airbag of the Japanese airship then floats in the air, and it can be seen from afar.

Although the Japanese airship did not shoot down the Monkey King's airship, it drove the Monkey King airship away (at least that's what Hiroki Izawa and Yuan Shikai thought), Hayazawa Yuki thought that they had made a great achievement, so they rested after landing, and held a celebration party in the evening, which was full of jubilation.

The Japanese army was jubilant, and Lin Gecheng and everyone were depressed, although they did not lose the battle, but the appearance of the Japanese airship brought them a different kind of shock, they had always thought that the Monkey King airship was the most powerful airship in the world, but today I saw the Japanese airship, and saw that the Japanese airship was equipped with ten Grimm fast guns, and an unprecedented sense of frustration hit instantly.

After several hours of sailing, the Monkey King airship finally landed at the Hainan base, and Lin Gecheng sent a message to Lin Fei while letting his subordinates rest, reporting the news that the Japanese army had dispatched airships to participate in the battle.

At this time, Lin Fei was dealing with the air raid in Macao, which killed more than 200 Chinese people, injured more than 300 Chinese people, and damaged more than 300 houses to varying degrees.

With the help of the wind, the fire burned down all the buildings on three streets of Macao, and the direct economic loss was as high as more than 5 million Chinese dollars, and if other losses are included, this figure will be even greater.

Lin Fei was furious when he heard the news, and ordered the Ministry of Foreign Affairs to summon Kang Youwei, the Qing ambassador to China, and asked the Qing government to explain the matter.

Lin Fei instructed the General Information Bureau not to report this matter for the time being, so as not to anger the people and ask Lin Fei to conquer the whole of Guangdong, and Lin Fei had already determined the direction of the next march, that is, Sichuan and Guizhou, both of which were in the remote areas of the Qing State, and the defeat would not excessively stimulate the foreign powers.

Lin Fei also learned from the report that the Qing Kingdom was attacked by airships in Macao, which made Lin Fei very surprised, how could the Qing Kingdom also have airships, Yuan Shikai also showed rockets a few days ago, and now there are airships, what is going on!

Lin Fei was wondering about this matter, Lin Gecheng's report arrived, Lin Gecheng was talking to Lin Fei by phone, and after he told the whole story, he exclaimed: "Your Majesty, how can the Japanese airship be so advanced?" ”

Lin Fei thought for a moment, "Don't be surprised, according to what you just said, the size of the Japanese airship airbag is about the same as ours, and the size of the pod is three times the size of ours, which shows that the buoyancy generated by their airbag is much larger than ours, and the only reasonable explanation is that the Japanese airship uses hydrogen as a filling gas." ”

"The Japanese are crazy about using hydrogen as a filling gas, everyone knows that hydrogen is in danger of explosion."

"It's not crazy, can it be Japanese?" Lin Fei teased, and then changed his words, "It's just my guess to say that the gas they are filling with is hydrogen, you need to verify my guess, so you can immediately contact the secret service and ask them to immediately go to reconnoiter the Japanese airship." ”

"The Japanese airship appeared when you left the port of Guangzhou, so their station must not be far from the port of Guangzhou, let our agents look near the port of Guangzhou, we will definitely be able to find the Japanese airship, and then observe whether the gas in the airbag of the Japanese airship is released, if not, the filling gas is likely to be hydrogen."

Lin Gecheng replied: "I understand, Your Majesty, if you are sure that the gas filled in the Japanese airship is hydrogen, wouldn't it be much easier?" ”

"Why do you think it's easy to fight?"

"Since the Japanese airship is filled with hydrogen, won't the Japanese airship explode with a light hit with the Green Quick Cannon shell?"

"How is that possible?" Lin Fei smiled bitterly, "Use our existing artillery shells to hit the Japanese airship filled with hydrogen, the Japanese airship will not explode, the shell will pass through the airbag at a very high speed, and then leave two small holes in the airbag, to hit the Japanese airship filled with hydrogen, we need to improve the shell." ”

"Improve the shells? How can it be improved? ”

"The shells you are using now are all high-explosive shells, and the cloth of the airbag is very soft, not enough to trigger the fuse of the shell, so it is difficult for the high-explosive bomb to explode, even if the high-explosive bomb explodes, it is not enough to detonate hydrogen, because hydrogen has no oxygen to help combustion, so we don't think about making the high-explosive bomb explode, so we use it as an armor-piercing bomb, first punch the airbag out of a hole, and then the air enters the airbag, mixes with hydrogen, and then we shoot another shell - incendiary bombs."

Lin Gecheng asked in surprise: "Molotov cocktails?" Is it the kind of cloudburst bomb used by the Army? It's too big for our Grimm cannon to fire. ”

Lin Fei said with a smile: "Of course, the incendiary bomb I am talking about is not a cloud burst bomb, but a shell filled with aluminum powder, which can be burned to emit huge heat, which is enough to detonate a mixture of hydrogen and oxygen." ”

With the establishment of the non-ferrous metal processing center in Southeast Asia, Lin Fei's electrolytic aluminum industry is moving forward steadily, but at this time, Lin Fei's electrolytic aluminum technology still has some insurmountable shortcomings, that is, high power consumption and low output, but this is also a matter of no way, after all, the electrolytic aluminum industry has just started.

The aluminum produced by the electrolytic aluminum industry is all used in the military industry, including aluminum alloys for airships and airplanes (at this time Lin Fei was conducting pre-research on aircraft), aluminum powder for incendiary bombs, and so on.

Lin Fei explained these things to Lin Gecheng, and asked Lin Gecheng to act, and Lin Gecheng then informed Lin Fei's instructions to the agents in Macau, and the agents immediately entered the port of Guangzhou to reconnoitre.

Because the Japanese army had just arrived, there were no strict defense facilities and secrecy measures in place, and the Huaxia agents easily saw the details of the Japanese airship and reported the situation of the Japanese airship to Lin Gecheng.

Lin Gecheng saw the agent's report, and his heart was secretly happy, first of all, the report said that the Japanese airships were floating, which showed that the airbags were filled with hydrogen, and secondly, there were as many as six Japanese airships, and Lin Gecheng was also worried that there was only one Japanese airship, which was not enough to fight.

Aluminum powder incendiary shells have long been produced at the military factory in Hanoi, and this new type of artillery shell is about to become the main artillery shell of the Huaxia artillery, and under the mobilization of Lin Fei, this kind of artillery shell was quickly transported to the Sanya base on Hainan Island.

Lin Fei instructed Lin Gecheng to mix aluminum powder incendiary bombs and ordinary high-explosive bombs into the bomb bay, and every five high-explosive bombs were followed by an aluminum powder incendiary bomb.

Lin Gecheng followed Lin Fei's instructions, reloaded the shells, and then formulated an attack strategy, that is, the four Monkey King airships were all dispatched to smash the nest of the Japanese airships, if the Japanese airships took off to fight, then they would explode them in the air, and if they did not take off, they would be destroyed directly on the ground.

On December 13, four Monkey King airships, under the leadership of Lin Gecheng, flew to the base of the Japanese airship, which was between three mountains, and it was very obvious from a high altitude, so there was no problem with the target designation.
